 Thank you Mike. My name is Graham Moss. I'm from the Australian Building Code Board. Today I'll be taking you through the technical content for the changes for NCC 2019. As Mike said this is the first amendment since going to a three-year amendment cycle, the first scheduled amendment, and so we have a lot to get through today. We're going to do it this way. What we'll do is we'll go through volume one first and as we go through volume one we'll pick up the changes that are also the same for volume two. After we've been through volume one and picked up those same things for volume two we'll go through the content for volume two that has been that we haven't covered on the first pass through. That's the changes to the NCC that we'll cover. Alison Scotland from Standards Australia will cover some of the changes to reference standards and after that there's a wrap-up session. I'll provide a few more updates and in all this there's opportunity for questions as well. So if you do have a question please wait until we call for questions and that's the same for Alison's session as well. Please jot them down as we go through and when we call for questions make opportunity to ask you questions then. I do ask however that the questions do cover content of the seminar. You might have a project back at the office you got a question about that's fine. Come grab me in the break or after the seminar and we can talk about those particular questions then. While we're working through the changes there'll be these icons on the screen to indicate the volume that that particular slide applies for. The blue one for volume one the red one for volume two and the green one there for volume three the plumbing code of Australia. Now today's seminar is not about the plumbing code of Australia this is about the building code of Australia volumes one and two. However there's a number of changes which are also contained in volume three that are changes that we're going to be covering today for volumes one and two. So for that reason you'll see that green icon there as well. On your seats there was some material there you've got some information you've got the lovely Z card which folds in and out like a Z. That's an update but we've also got the lists of amendments for each volume. Stands Australia provided some information there as well and we've also provided a specific list of amendments for reference documents. So follow those away but if you have colleagues back at the office abcb.gov.au forward slash abcb forward slash seminar all these documents except for the Z card because your screen doesn't do that on your computer at least not yet. All those documents those informative documents are available at that website and if you like to use electronic copies well of course then you can use that as well. Now of those documents I need to draw your attention to the lists of amendments. Now the list of amendments are an appendix to every addition of a new NCC and they're very handy you can see what changes occurred that year but I really want to draw your attention to it this year because and we've provided an extract for you on your chairs and at this website. This year it's important because today's seminar is not going to cover every change. There's three years worth of change at the end of today's seminar. You're going to be aware of the majority of changes but you're not going to have a detailed look at all of the changes. There's even going to be changes there that are important to you but probably haven't been mentioned in this seminar so do when you get back to the office have a look at that list of amendments and see what else has changed. Now these are all sellout shows so you might have some colleagues that aren't here today. Fear not there's going to be a video on the internet of this particular seminar so you can grab that through our website or straight on the YouTube. Now the so you say colleagues who have missed it can can can download that on the internet and also if you want to do a refresher on this seminar or if you want to keep some of that content that on this on the screens it's all going to be available on the internet in a webcast that should be out sometime in May and also the plumbing colleagues they're going to have a plumbing seminar also available by webcast on a website also in May. These are the adoption dates for NCC 2019 so first May this year is the adoption date it's when the NCC 2019 becomes the current code however it's hard to talk about adoption dates for NCC 2019 without noting those other dates on the screen. The first there is the energy efficiency transition so all the energy efficiency transitions sorry all the energy efficiency provisions receive a transition period they come in and they on the first of May next year until the first May next year you can use both so up until the 30th of April next year you can use NCC 2016 or NCC 2019 for energy efficiency but after then can only use NCC 2019 after the 30th of April so that's that transition period and also talking adoption for NCC 2019 we can't talk about that without noting that the fire safety verification method is not enacted until the first of May next year. Talk about that more later but those are our adoption dates for NCC 2019. As Mike said we're going to touch on a lot of content today some of these changes come out of our deregulation work so for example the battery protection there in C212 that's that's an example of our deregulation work some of these amendments we're going to talk today are clarification changes so there's D115 measure method of measurement that's a clarification change which has come in this year. We're also going to touch on the changes for sprinkler protection with NCC 2019 class two and three buildings greater than four stories in height require mandatory sprinkler protection under the deem to satisfy provisions so you're probably aware that's a big change usually it kicked in at 25 meters effective height except for other circumstances such as fire protected timber buildings but 2019 rising stories four or more sprinkler protection kicks in under the deem to satisfy provisions we'll talk about that today. You might have also heard of our performance project there's a lot of work done about the performance solutions and some of these changes come out of that as well so we've got some quantified performance requirements and a number of verification methods. There's also condensation for other things we're touching on a number of changes in volume two and a lot of these have come out of our acceptable construction practice review project or the ACP review project and volume two has been worked through using great project officers using working groups to find opportunities to make the content better and so a lot of those changes are reflected in NCC 2019. I have to say also that there's a lot of content that actually isn't going to be covered today that came out of that project for instance our pine areas does anyone here do work in our pine areas? If only the same response happened in birth so yeah we're not going to touch on our pine areas and there's some changes to the code in case you do find yourself doing in our pine area unlikely up here but that's an ACP review change that isn't going to be a part of this seminar. Another project we've had is readability now it's been said very often correct me if I'm wrong that the NCC is not a good read doesn't doesn't make good reading yeah you know it's right there next to Harry Potter on your bookshelf not really it's a complex document it's full of long sentences it's hard to understand so what we've been doing is been rewriting it to make it a lot easier to understand and already the volume 3 the plumbing code has been entirely rewritten under this readability project using much simpler language and also for NCC 2019 you'll find that section A of volume 1 and part 1 of volume 2 have been rewritten under this readability project now it's not just about the language making the language easier it's also about the structure we've been making changing the structure to make it easy to understand because it was found that this the three different volumes with their three different structures was made hard to understand so we're making a first step towards a common structure with NCC 2019 and that's reflected in the governing requirements on the left of this screen you'll see the current structure for section A for volume 1 and part 1 for volume 2 now they're very similar at the moment you know there's some changes volume 2 doesn't have united buildings and things like that but we're moving towards a common structure as you can see on the right a lot of the content's been moved to the new governing requirements some of it's been moved to the new common schedules but this is a step towards a common structure for the NCC because this section A or this this governing requirements on the right is going to be in volume 1 and volume 2 for NCC 2019 here are the schedules so again the contents come out of 2016 and been moved across to these common schedules the first schedule of the appendices for each state and territory the second schedule are the abbreviations and also the the symbols so these have always been there as an appendix so that's scheduled to right now definitions and reference reference documents make up schedules 3 and 4 schedule 5 is what used to be spec A 2.3 in volume 1 and schedule 6 is what used to be spec A 2.4 in volume 1 ah the first phone get that on to silent please by the way do you know that that's one of the standard ones you can change it doesn't that for that make it more exciting thanks mate and the 7th schedule the fire safety verification method the 7th schedule that's that's because that covers so much of the code of volume 1 that's been given a schedule there in the common schedules now I said it's all common and so here is a zoom in on part of schedule 3 the defined terms and you'll see that you've got plumbing terms right next to building terms so backflow prevention devices right there next to average specific extinction area it's it's part of the the common schedules that we're moving to and I mentioned the language so here's an example of a 6 which is about classification of buildings part of this rewrite is to use these sorts of exemption boxes and limitation boxes and what these do they take a concept about classification of building and it pulls that concept apart into the different parts so that instead of having one concept all in a big sentence which might go across a sub cause maybe into the next one it's been pulled apart into different ideas to make it easy to understand it's the same content as just expressed more simply you'll also see a new numbering system especially volume 2 users that is now a volume 2 numbering system right there that numbering system could be what you see for NCC 2022 throughout to make it common through all volumes now what we're talking about readability and changes it's hard to go past this one here now a lot of tables in the NCC look like this there's titles which stretch across various columns because that title is relevant to all the columns in these merge cells and this arrangement of tables can't be read by technology so technology reads codes but technology can't read tables like that so for this reason and we have an obligation as the Australian government to make our content accessible so we're replacing tables like that with tables like this the merge cells disappeared again it's the same content this one's from volume 2 for attachment of hard board cladding it's the same content just expressed in a different way we're now going to work through the tech content of volume 1 and like I said before we're also going to pick up the changes to volume 2 which are common to both volumes and so we'll be covering those as well verification methods there's a few new verification methods in volume 1 quite a number most of these come out of that performance project I mentioned earlier but some of these are from other works such as the energy efficiency work and also condensation management that's a new verification method my first type that should be FV6 I do apologize FV6 condensation management now we're not going to cover all of these in detail some yes not all of them but what we do have for you are handbooks now every verification that most sorry most of the verification methods here will have a handbook which will accompany so if you're going to find yourself using one of these verification methods jump on our website there's likely a handbook to help you in applying that verification method and of course verification method is always an option you can use the dean to satisfy you can use another performance solution or if your project suits you can use one of these verification methods now we'll move into section B and into the structural reliability verification method this one came in in 2015 and it's recently had a review and that review has changed a few things in the verification method most notably the target reliability indices have increased so you can see a few of those there from 3.8 have been bumped up four or more we've also included an option in that verification method that you can derive your reliability index from an equivalent dean to satisfy provision and there's a few other little changes as well in there the formulas remain the same same idea just a few little reviews in that verification method so if you use the structural reliability verification method be sure to have a look at that and of course the handbook has been updated to suit that as well so that's BV1 and in volume to also V2.1.1 now we move into section C and the first change I'm going to mention is C1.9 there's a few changes in C1.9 C1.9 sub clauses A and B line out set out some circumstances where parts of a building need to be non combustible and that includes external walls and shafts and a few other things when I say external walls of course that's external walls of type A and type B buildings at C1.9 A requires to be non combustible sub clause D lists some things that don't have to be non combustible in those circumstances it's a concession and what we've done is we've grown that list in 2019 to include termite measurement systems glass and thermal brakes in associated with glazing because these are commonly found in external walls and they're also low risk there's another change in C1.9 non combustible building elements and that's in E so E is the sub clause that sets out when wherever in a building you have to have something non combustible doesn't have to be non combustible in sub clause those items listed in sub clause E don't have to be non combustible we've added to that sarking which is thin no more than one mil thick and also if it has a spread of flame index of five or less again this is a low hazard a low considered to be low hazard therefore acceptable to put that in as a concession particularly because everything around is going to be non combustible next change is to C1.10 fire hazard properties so sub clause C is another concession it lists the items that don't have to comply with the fire hazard properties of specification C1.1 and for a long time C Roman 5 here applied the concession to timber faced solid core doors and timber faced fire doors for NCC 2019 2019 the privilege changed to bring in all timber faced doors because timber faced hollow core doors again a low hazard and so it's appropriate to extend the concession to their also back in 2016 we introduced a number of timber we introduced the timber mid-rise provisions as they're called this is where you can you construct a building out of fire protected timber up to an effective height of 25 meters the fire protected timber could is usually this cross laminated timber as indicated on this diagram here and of course there's a few things that had to happen to your building to make that work including sprinkler protection now the big change for NCC 2019 is that while previously it only applied to class two three and five buildings now the concession apply now sorry not the concession these provisions apply to all classes of building covered by volume one there's a few other little changes such as how specification a 1.1 which is about the which is one of the specifications that goes with this content has been moved to c113a so if you're working with timber mid-rise buildings do jump on the list of amendments and have a look at the changes that have occurred to these parts mainly in c113 now i said that these buildings have to be sprinkler protected very soon i'm going to be talking or later in this presentation i'm going to be talking about a new classification of sprinkler system as specified under some technical specifications the fpAA specifications you can't use an fpAA sprinkler system for a timber mid-rise building if you remember nothing else today remember that you can't use an fpAA system for a timber mid-rise building i'm also going to draw your attention to that website woodsolutions.com.au because wood solutions they've already got on their website a number of handbooks to help with the the current timber provisions they've been busy and they've been creating handbooks for to to suit these changes to assist in the use of these provisions for buildings other than class two three and five so if you're going to do a fire protected timber building have a look at woodsolutions.com.au c212 that's the provision in volume one that requires separation of some hazardous equipment and currently batteries in there require separation if they're both 24 volts and 10 amp hours now that requirement has ridden way back when lead acid batteries were the norm and we did some research and found that battery technology has been changing we're seeing more lithium-based batteries in buildings and we also found that the old provisions were were were a burden and they were were overly burdensome so we've amended the triggers as a result of that research and as you can see for 2019 the provisions kick in at 12 volts and 200 kilowatt hours now to give a bit of perspective when you have a battery which is connected to your house solar system that's about 10 kilowatt hours so it's a pretty significant battery system that we're talking about to be protected by c212 and you also see a new defined term battery system there so that batteries that that's a new defined term for 2019 it aligns with the defined term found in the relevant Australian standard for the batteries that you'd find used in buildings and it means either one battery or a number of batteries that have been joined together parallel or series moving to spec c25 and a small change there's a small change in the specification that happens throughout this is how it appears in ncc 2019 and where it reads zone pressurisation system that used to say zone smoke control system this one's a clarification it was it's intended the concession to not have the smoke reservoir above the door applies only to zone pressurisation zone pressurisation systems rather than all smoke control systems so that clarification you'll find in ncc 2019 we're up to section d now and that brings us to two new verification methods for access dv2 and dv3 and of course access for people with a disability dv2 is a whole of building modelling system type of verification method and dv3 is about ramps now dv2 you compare a hypothetical reference building deemed to satisfy with the proposed building and you check to see if there's equivalent levels of access it's sort of like a jv2 for energy applied to access for people with a disability dv3 is about ramps and under dv3 you can verify that a ramp is satisfactory after calculating the pushing force required to go up the ramp the braking force required for coming back down the ramp at a suitable speed and to make sure that these these forces are within certain parameters there's also other requirements there about the time taken and a few requirements about the crossfall on the ramp the surface of the ramp and things like that you'll also notice a blanket rule you can't use this verification method to create a ramp that's deeper than one in eight now of course this is a verification method and like all verification methods there are only options you don't have to go and get the calculator out and do the do the do the the formulas in order to derive whether the ramp's okay you can still use another performance solution or you can use the deemed to satisfy and create a one in 14 ramp which is inside all those parameters found in one in nays 14 28 point one now dv2 and dv3 get a handbook as well so if you're going to use either of these verification methods please also grab our handbook one of the changes this year is a clarification and here is the confusion that we're clarifying as shown on this hypothetical floor plan so on this floor plan we've got a required exit down the bottom left and a required exit on the bottom right a couple of fire isolated stairs in this scenario the yellow dot there is representing the point of choice the point of choice is determined under d1.4 or volume one this is where in that room up the top left there you can only go in one direction in order to get to an exit once you get to that yellow dot you have a choice of turning left or right in order to get to your exit so that's the point of choice as established in d1.4 you turn to d1.5c and that requires us to measure the distance between the required alternative exits down the bottom left and the bottom right and the maximum distance for that distance between the two is usually 60 meters however for class two and class three buildings and also the patient care areas in a class 9a hospital the distance comes down to 45 meters so that's the existing requirement in d1.5c we have to measure the distance between these required alternative exits but how do we measure it so this is the confusion that we're seeking to clarify so some people in this room would measure it along this path the most direct measurement between the two exits however some people in this room would measure it this way they'd take in the point of choice the reason some people here would take in the point of choice is because they'd be reading this provision in d1.15 d1.15 is that provision which sets out how you go about measuring your distances for exit purposes in in d1 and we've always had d1.15e here which talks about how to measure between alternative exits required alternative exits what we've done is introduced these words this year for the purposes of d1.5c so this is clarifying that when you're making that distance but when you're measuring that distance the maximum distance between required alternative exits that you must take in the point of choice as established in d1.4 so going back to a hypothetical floor plan this is the correct method of measuring the distance between alternative exits d2.21 in volume one is the provision that sets out requirements for operating door latches we've made a couple of changes to d2.21 this year the first change is a new subclause that provides some parameters for the manual controls that are not located on a power operated door so think of your sliding doors or your auto doors there's a minimum requirement for these operation controls they have to be at least 500 millimeters from an internal corner so that so the wheelchair user can come up and use the button and there's a few other requirements there including some proximity requirements believe this or not it is possible under the current ncc that if those doors at the back of this room were power operated the button used to open it could be right here it's no proximity requirement so we've introduced that here for ncc 2019 and of course the intent of these requirements is to ensure that evacuation is straightforward and orderly the new subclause also mentions when you need to have braille and tactile signage to identify the the manual control so so that occupants can use the doors easily in an emergency the second change to d2.21 is to provide some clarification to subclause d2.21 b4 this is the subclause it's in there at the moment that requires a door to automatically unlock on the activation of a detector or a sprinkler system has to automatically unlock it doesn't have to automatically open and that's fine but if you read the current provisions it actually doesn't clarify that you need that door needs to be readily open or so we've adjusted that and ensured that the door is readily open and of course this would mean providing appropriate door hardware so the door unlocks so to unlatch the door would have to have the correct hardware you leave a handle or a crash bar in 2016 the Australian government commissioned or undertook a review of the access to premises standards and some of the recommendations from that review led to some changes in volume one most are quite minor and here are some from d3 the first one excuse me the first one is a clarification in subclause d of d3.5 this is the one that says existing existing provision for a small car park where you have five or less car spaces you don't have to put a sign to say that this is used only or exclusively for a person with a disability and you don't have to mark it in that way now it's always been the case except the text was a bit hard to understand people were doing it in different ways so that provision has been clarified there's signage exemptions there in d3.6a this one's about signage for sole lock units for your class 2 class 3 and your class 1b boarding house so think of it if you're a wheelchair user you ring up the hotel you book a room you book an accessible room you go to that room you don't have to have the door on the sign on the door that says this is a wheelchair accessible facility I know that already I booked the room and the same applies for the class 1b now the amendment here is a bit of a clarification bit of a fix because it was recognised that there's also class 9c buildings where it was not necessary to put the sign on the door to indicate that this is a wheelchair accessible facility and another small clarification in there comes about how in a class 1b you don't necessarily have a sole occupancy unit you could have a bedroom so the the provision's been amended to take that into account d3.8 there you may recall that in an aged care building you can use a dome button on the handrail instead of the tactile ground surface indicators so the requirement for dome buttons is always sitting in it sits in AS 1428.4 the specifications for that at the NCC 2016 there's no direct reference to 1428.4 you have to go through and find 1428.4 as a secondary reference what we've done the premises standard review recognised that a direct reference was more appropriate so that's a little amendment there in d3.8 cinemas this one's a correction because under the current NCC you need to provide range representative wheelchair seating in all cinemas range representatives seating so you've got the premium the business class premium economy and the economy it happens in cinemas you have to have range representative seating currently in all cinemas now it was always the intent that this would only kick in where cinemas sat more than 800 people so that's a correction that's been found that you'll find in NCC 2019 and pools there's that point in d3.10 there was a double up in the spec as well as the provision we've just removed that double up from the provision so the requirements the technical requirements found in the specification of d3.10 that brings us out of section D into section E and we come to firefighting equipment and we come to hydrant provisions under E1.3 of volume 1 this is a change that came from the reg reduction project the first change is to do with how you measure if a fire brigade station is available to attend a building fire this is how it appears in the current NCC you have to have a fire brigade available to attend a building fire how do you measure that we've put some numbers in NCC 2019 50 kilometers and of course the station needs to be have equipment the station within 50 kilometers measured by road has to have equipment which can use a fire hydrant these changes also appear in H3.9 for farm buildings so continuing on to sub clause B this one there's some changes that came out of some common performance solutions that we found being applied across Australia so because they're so common and they were able to be replicated we put them in the code and these are two new concessions the first one's in sub B which is emitting requirements of the standard some requirements of the standard when you're building a sprinkler protected and also in C there we've given greater flexibility for when you protect a booster assembly so currently you've got the the large protection that has to happen when your booster is anywhere between 0 and 10 meters what we've done is put an intermediate level of protection when you're between three and a half and 10 meters so a few common performance solutions found themselves into the pages of the NCC for 2019 the office we at the ABC be commissioned a risk assessment to determine if fire extinguishers in class five buildings so those are your office buildings of course a class five office building used for professional purposes we commissioned this risk assessment to determine if fire extinguishers could provide an acceptable level of life safety compared to fire hose reels the outcome of that risk assessment was that the fire extinguishers actually do provide at least an equivalent and in some cases a better level of life safety than fire hose reels net result is that in NCC 2019 you no longer require fire hose reels in class five buildings you provide portable fire extinguishers instead so here's e1.4 explaining that that this provision about fire hose reels does not apply to a class five building and here's e1 and here's e1.6 which is setting out the portable fire extinguishers must be included in the class five building to find that change in NCC 2019 residential care buildings now residential care buildings this is a new concept it's a new defined term but it's a lot like an old one that you'd be familiar with which is the aged care building what we're doing is we're taking the aged out of residential aged care building and the reason for that is because aged care buildings extra attract requirements such as sprinkler protection for on account on account of the fact that the occupants are vulnerable but occupants can be vulnerable for other reasons than being aged there can be people with a disability or it could be the very young so you'll find a change in NCC 2019 all under the title of residential care buildings here's a brief summary of the different types of class three and class 9a and class 9c buildings that you could expect to find the first row there is not a residential care building that's your common class three building where the level of care provided is none or low and there's no need to provide assistance for evacuation but you'll find other types of buildings which are all class three or class 9a or class 9c below that row and those are buildings where some level of care and some level of assistance in evacuation is required and that includes the aged yes that's the the last row there the 9c aged care building but it also includes other buildings where people are required people do require a level of care on account of being young or on account of being having a disability the NCC already requires sprinklers in class three class 9a and class 9c aged care buildings but now NCC requires sprinkler protection for residential care buildings be it class three class 9a or class 9c we do maintain provisions for aged care buildings which are appropriate for aged care buildings such as we talked about the dome buttons instead of the tactile ground surface indicators in as in d3.8 there earlier those those still apply to the residential aged care building which is a type of residential care building but there's also the residential care buildings which are class three class 9a and class 9c sprinkler protection we're still in e1.5 and we have some significant changes this year for class two and three buildings and we discussed this already most would be aware that the for class two and three buildings apart from a subject of other provisions such as for timber mid-drives the requirement for sprinkler protection doesn't kick in until 25 meters effective height under NCC 2016 in the deemed to satisfy provisions it is an option you can still install sprinklers you enjoy a level of concession but for NCC 2019 that's changed if you have a rise in stories of four or more that's your top left box there rise in stories of four or more for a class two or three building so that's your your apartment building your hotel building if the rise in stories there's four or more a form of sprinkler protection will be required three-story walk-ups and anything lower no sprinklers required but rise in stories four or more ask yourself that question if it's yes move into the next question is my effective height 25 meters or less if you exceed 25 meters effective height then of course you go down the right hand side there and you end up with sprinkler protection as currently is the the requirement under the NCC 2016 but if my 25 meter if my effective height is 25 meters or less and my rise in stories four or more I need to provide some form of sprinkler protection you can still use the AS 2118 systems part one part four part six whichever is applicable or you can use new reference documents these FPAA ones that I've got listed there the FPAA 101D or the FPAA 101H these are new reference documents for NCC 2019 and they outline a sprinkler system which is more cost-effective than your regular AS 2118 system I do have an asterisk there and that asterisk of course says subject to other requirements such as the timber mid-rise provisions I mentioned earlier however most buildings four stories or more 25 meters effective height you're likely going to be using these FPAA technical specifications and here they are the D in FPAA 101D stands for domestic water no prizes for guessing where you get your water for the system from the taps off the domestic supply and of course that's a lower grade supply than what the AS 2118 series requires the H stands for hydrant water supply and that's a system that taps off the hydrant system of course and these specifications technical specifications are outlining systems which are lower grade than an AS 2118 system on account of their water supply and other you could call them concessions found inside that technical specification these specs published by fire protection authority Australia sorry fire protection association Australia and for a copy you can go to their website fpAA.com.au I'm also told that FPAA are developing a handbook to cover these technical specifications I'm also told that they're going to be putting a seminar series out on these technical specifications so keep an eye on their website for that information now because they're more cost-effective systems or a slightly lower grade system there are some limitations to when they can be used besides how they can only be used in buildings that are less than 25 meters effective height and some of those limitations are set out in this table now you can see that there's situations where there's multi classified buildings so the provisions do note that multi classified buildings are class two and three buildings and you can also notice that the D system with its lower grade water supply can be used in less scenarios than the H system and it comes it comes down to how much of the building is another class of building amongst a few other little things like that so these rules are all set out in specky 1.5 course two about which system you can use but now that we've got these mid-rise buildings less than 25 meters effective height with mantry sprinklers we also get some concessions these are the concessions or some of the concessions for the D system you get some reduced frls you also get increased travel distances you get some concessions over your smoke alarm or your smoke detection alarm systems and the system the level of concession of course correlates with the level of system all the way from the FPAA-101D system through to an AS-2118 system and all these concessions are set out in a brand new specification specky 1.5A and the concessions and requirements and provisions around the smoke detection alarm systems are set out in speck e2.2D that's also a new specification for 2019 and speaking of concessions you may recall that throughout the NCC there's a number of concessions which apply to sprinkler protected buildings now here's here's an example this is c2.6B from the from the spandrel provisions separation prevention of fire from on switch next now this is just one example of many however most of those concessions for sprinkler protected buildings are not appropriate for an FPAA-101D or FPAA-101H system so for that reason you're going to find exclusions like this dotted throughout the NCC where the sprinkler system concession is there where that concession is not appropriate for an FPAA system some are however a lot of them aren't which is why you find these throughout the NCC the next change is also relevant to sprinklers and you may recall that under NCC 2016 in a lift machine room in other similar areas you had to have a dry system that was found on our reg reduction project to be a bit onerous and so what we've done is we've reduced burden and we've made some simpler included some simpler to achieve requirements it doesn't have to be a dry system anymore it just have to be able to you just have to protect the heads and be able to isolate those sprinklers for the lift machine rooms and the lift shafts etc from the other sprinklers in the building there's also some amendments to table e2.2a and spec e2.2a which are clarification amendments we've included some changes to clarify that when we talk about zone smoke control we're actually talking about zone pressurization systems which are vertical pressurization systems where the fire compartments are listed above them are found above and below one another now this clarification is all throughout the NCC but here's a hypothetical example from table e2.2a it's a class 9a hospital it's more than 25 meters effective height and it's made up of fire compartments as shown by each box now the zone pressurization that we're talking about is for a story so those blue ones up the top there there's stories which are fire compartments above and below one another they're vertically separated fire compartments therefore they're provided with zone pressurization for some reason we've got two fire compartments on the ground floor there those do not need to have zone pressurization while we're in spec e2.2a it's worth mentioning that we've made a few clarification changes the technical requirements are still the same what we've done is done some restructuring and a bit of rewording to make this provision of the specification easy to understand and so for example there's a lot of class 2 and 3 buildings that can use a combined clause 3 and 4 system combined smoke alarm and detection system and when you're doing one of these it's a bit hard to keep track because you've got to get bits from clause 3 you've got to get bits from clause 4 people found it a bit hard to keep track so for NCC 2019 your combination system gets its own clause a clause 5 system in spec e2.2a so next time you're in e2.2a just have a look at the spec you'll find a few changes that would make it easier to understand now the next change is to do with emergency warning and intercom systems and for a long time e4.9 has required an eWIS system for the residential parts of a school now a school is a defined term and a school for the purposes of the NCC includes a university so technically when you provided your so technically for a long time it's the case that when you have an eWIS system you have to provide that to your primary school your secondary school but also your university student accommodation block even though your university student accommodation typically won't have fire wardens and things like that you'd expect in a in a boarding boarding school so for this reason e4.9 has been amended to limit eWIS systems only to primary and secondary schools no longer a DTS requirement to put them in university student accommodation now if people are still awake you'd probably notice another change on that screen can anyone see it no one's found it this is an oh that's a scratch not a hand no one can see this other change that's on the screen e4.9 in NCC 2016 the title of this provision is sound system and intercom system for emergency purposes or SISAP oh yes I knew that everyone says yep I knew that it's it used to be the SISAP it's changed for NCC 2019 to emergency boarding and intercom system or the eWIS and the reason for this is that the reference document to do with these systems AS 1670.4 that's been updated and we've referenced the updated document and the title in 1670.4 used to be SISAP now it's eWIS so we've just changed to keep track with the Australian standard and that change also appears in G3.8 for atriums section F we've had some deregulation work and some of the changes in section F fall into the deregulation category and that includes the wall floor junctions in laundries and WCs NCC 2016 has to be waterproof NCC 2019 you only have to have it water resistant and also we've had another dereg job there in facilities for employees when you have your class two with 10 or more solar units that's what I like to call the janitor's facility and so many times I bring up the architect and say you forgot your janitor's facility whereas I don't have to make that call anymore because that requirement has been removed for NCC 2019 you no longer have to provide another sanctuary facility for employees where you have 10 or more solar units. In NCC 2019 we now have requirements for facilities for adults with a profound disability who require a change table. Now these are different to your usual accessible wheelchair facilities or your ambulatory facilities and they're also in addition to those existing facilities. You may have come across these before there's a a scheme in Australia called changing places and under changing places building owners are able to put an accessible adult change facility into a commercial building and have their facility excuse me have their facility verified by the changing places scheme. These new provisions in the NCC volume one so that's F2.9 and specification F2.9 reflect the changing places specifications. It works like this the clause F2.9 is the trigger clause. It sets out the buildings which require an accessible adult change facility. If you require it then you go to the specification to find the details about that facility. So here are the buildings in F2.9 which are required to have a facility. You've got shopping centres with three and a half thousand or more occupants so that's going to be a shopping centre of four and a half thousand square metres. You've also got class 9B sporting venues where you have more than 35,000 spectators so it's a large sporting venue. You've got your museum your gallery your theatre those sorts of class 9 buildings we've got more than one and a half thousand patrons and also airport terminals are triggered by these new provisions. So F2.9 sets out that you need a provision you go to the specification need to provide the facility you go to specification F2.9 for the requirements of that particular facility and as this diagram straight from the specification shows you're going to need a change table a change table which as I mentioned in the dimensions they're in specification F2.9 to make it suitable for an adult. You need an electric hoist above the change table. Now about that hoist that hoist has to be able to carry 180 kilograms so when you're specifying the ceiling for these rooms you might want to be sure that that ceiling can also take 180 kilograms. You also need a toilet with the fold down grab rails a basin circulation spaces all these things as detailed in specification F2.9. We moved now to natural light and this is where the quantification of performance project has quantified some performance requirement. Currently the requirement for natural light is that you have to provide an adequate level of illumination that's been replaced with this with an average daylight factor of two percent. Now this is an established measure it's not something new there's a lot of design software which uses this ADF average daylight factor but if you design software if you don't have means of measuring that available to you we haven't left you in the dark that's a joke we haven't left you in the dark there's a new verification method that you can use thanks Luke there's a new verification method with the formulas to calculate your ADF. Now of course you don't have to use this you don't have to come up with an average daylight factor you can still use your 10% window in order to achieve the requirements of that provision. We've made a change also in artificial lighting just like natural light it's an appropriate level of illumination and this is both volume one and two currently the forms of requirement shows that appropriate level of luminance we put a number on that that's 20 lux and you'll recognise that that comes straight from AS1680.0
