 Good afternoon. This is Martin Despeng, whoops, no, this isn't Martin Despeng. This is Martin Despeng's substitute. Martin has to teach a super duper class at UH architecture this afternoon, and he has subbed for me, so I'm subbing for him. My name is Howard Wiig, I normally host Code Green for Think Tech Hawaii, so you are on the Think Tech Hawaii site, and we have as our distinguished guest today Mr. Sean Mosley, Territorial Manager for Breezeway. What in the world is Breezeway for those who are not heartened sold into the construction industry? Breezeway is a jealousy window manufacturer out of Australia, yes, still in Australia, yeah. The jealousy windows that we are seeing today, not just Breezeway but competitors, are way way way superior to the jealousies that I grew up with and any other local people grew up with. If we went to Auntie's house and Auntie wasn't in and we wanted to get in, we'd simply go around to the back, and I think even without pliers, we would just detach the louvers just a little bit, take out a few jealousy blades, crawl in and we were at home at Auntie's house. We could actually reattach the louvers with our hands. Those were the old louvers, believe me, you know all technology is improving at six miles a minute, well not six miles a minute, a hundred miles a minute, and jealousy windows are no exception as we are about to see. We're gonna see how durable they are and they're if not totally burglar proof, very largely burglar proof and they seal very very nicely. When you get them sealed there's not a whole lot of air leakage as was the case. So without further ado let me introduce Sean Mosley welcome to the program. How are you today? I am doing very very very excellently. Thank you. Thank you for having me on the show and just as a introduction this is IECC 2015 what in the world is that? That is the energy code coming to a county near you and it includes, this is a Hawaii specific amendment to the national code, it includes specifically jealousy windows. Why? Because the energy code is intended to maximize energy efficiency and in many many homes that have air conditioning the the inhabitants don't use the air conditioning all the time because it's absolutely not necessary because we have a beautiful climate. Why not on cool days and nights turn off the AC and open up the windows? What are the best windows to open up? Jealousy windows so we put them in and they are a huge huge energy saver or maybe with the given the new president we will have in a couple of months a huge energy saver. So well on that very very cheery note why don't we go to our first slide and you know Sean Lee I was born and raised here and that looks really really familiar. Yeah so this is actually a true jealousy window in the essence of its form and this is what a typical jealousy from 1950 to 1970 will look like you'll see a handle on the right that's a crank style you'll see a white handle on the left that's a replacement and you'll see all the clips bent and this is actually a renovation job I took a picture of where the blades were falling out about three stories and injuring cars and possibly people you know there's a big distinction between jealousies and louvres because jealousies are the old style where they both when they're open they you know they offer absolute ventilation but when you close the jealousy you still have air leakage 1.2 CFM or greater the Cfm being cubic feet per minute yeah so with the louver when you close it you actually get better sealing than you would get with your front door so huge improvements in that the old jealousies that you saw in that slide there they were dissimilar metals you had zinc rivets you have aluminum frames and then when you have the electrolysis which is created its electrical reaction between salt and moisture and you get dissimilar metals it causes them to swell so the rivets start popping off and then the other thing is because like you talked about they want to break into the house once you bend that aluminum it's so thin it never bends back so you every time you take that blade out you actually destroy in the window it's the only way again I used to do it I just gave the example of my aunt's house because sometimes she wouldn't be there and the house would be locked and I would literally I didn't even need a screwdriver anything perfect it's perfect I mean if you're trying to escape from somewhere it's even better but if you're trying to make a house secure it's very very questionable because when the windows close you can still open it so yeah that's the old style yeah yeah I have a lot of people that get upset at louvers because they can they cannot break into them when they're closed without breaking the glass nobody wants to do that is this the appropriate time to talk about the difference between louvers and yeah yeah so they both go up and down okay so a jealousy goes up and down you lift and go up on the crank or you crank it this way but essentially the hardware is just going like this a louver actually properly designed that actually the hardware will spin and it pushes the clip against the jam on the window and seals it and what that does is it pushes the glass really tight so instead of it just touching it actually pushes it in so you create a good glass on glass contact what you get with that is hydrostatic pressure if you've ever taken two pieces of glass put water between them and you try to pull it apart you can't I remember you have to slide it off but with a jealousy because they don't totally tighten to each other you never get that hydrostatic pressure that's why if you take a hose and you spray the house down clean the windows grandma's gonna get upset with you because water is getting the house that's a big issue with a louver you can actually hose or power wash it down and everything will come down and go where it's supposed to go ahead so it's really the same concept in design but an improvement in the style jealousies started back you know 30s 40s and from the 50s and 70s we have a lot of the jealousies in Hawaii which are great when they're open because we get all the passive trade winds we got all the natural ventilation but once you close it and you got a storm you pray that nothing to get damaged and you can see with all jealousies there's damage on the wood on the walls there's always seems to be an electrical outlet right under the window single wall construction so on and so forth so the real definition between the two based in Hawaii standards and I will note that breezeway is originally Australian and we still have factories in Australian New Zealand and throughout the world but the Louvers we manufactured Hawaii are manufactured here in Halawa and have been for over seven years and we have provided product to Hawaii for over 40 something years so so there is a little an employment oh yeah yeah they're locally made they're definitely locally made and they're don't they're locally geared I mean I grew up with jealousies and truthfully after being in windows myself for all 28 years now I never liked jealousies as a kid or in the window industry until I came into the breezeway family because they never performed when they were closed so everyone just leaves them open and that was great absolutely perfect you know I'm thinking of my house and that's exactly what goes on yeah and then plus my grandmother make me take every blade out and clean everyone to get all the dirt out of the spots and so operated again I have to fix all the rivets and it was it it was an eyesore it felt like braces on the house and but the the trade-off was that it was an affordable window and offered full ventilation and didn't required air conditioning so if you leave any window open all the time it was fine and that that's the case in my house and I suspect in the case of many of our visitors current visitors our audience yeah yeah and that and that's great but there's a level of standard and safety you showed the energy code you know as days get hotter and whether you believe in climate warming or not as irrelevant the fact is when you have a hot day and it's just too hot to have and there's no trade winds and the corner winds are coming and you want to turn the AC on you don't want it all going out your window I mean you'll go to houses and see people who run AC all the time on jealousies and they got tape over every blade or they're gluing them shut yeah I mean that's an egress nightmare right there you know firemen don't like that too much yeah and I've seen the same thing our beloved public schools the temporary classrooms they used to be jealousy cooled now they're a sequel yeah they're having a huge challenge with that because of all the heat abatement they want to you know they want to air-condition when it's necessary and that makes total sense but when they want you know like my children go to public school in kanioi and on hot days they're going to run the AC where they can when they can on the cool day just open it up there's no reason for it in fact building occupancy health with natural ventilation and proper life cycles reduces sickness by 48% it's a proven fact worldwide if you run AC 24-7 in a scholastic environment your absent team is higher you actually have less kids showing up because they're living in recycled air getting more allergies more challenges the mechanical system gets more time because you have built we speak in terms of air exchanges yeah and when you have openings on this side and openings on that side you're going to get a tremendous air exchange yeah and I mean I grew up here I remember loving when the windows were open to be able to see the koala in kanioi Bay I mean it was just like that made me want to go to school yeah why don't we go to the the next slide here because this is quite a spectacular one we go up what in the world is all this color about here yeah so this is one of our projects that we did this is out of Australia and you see different greens in the glass so there's a lot of with a well-built louver there's a lot of aesthetic options for architects and designers in this case you actually have a color splash with the grass accident so it feels good when you walk into it but that's actually a solar shade too for the windows behind so you have a reduction of solar heat gain and you have an open air environment but it's completely protected from the environment for you know bad weather and so forth and it just has a good splash of color so that would be obviously more of an upscale but you can see the height of the louvers on that that's a consistent run and those are large blades and it's a testament to the quality of the hardware you know those blades are not going to be falling out and you're not going to be able to remove them without knowing how to do it and pulling them out up on a lift there yeah and you can see the way it's angled in you know that the tilt is so that it allows the air to scoop into the facade and into the building so it increases it obviously green glass is not extremely common in Hawaii it is a color that breezeway offers because in overseas and in foreign markets you know Australia New Zealand and whatnot outside of Hawaii architects like to throw into the different splashes of color for you know to show that it's not just the same old stuff I've never seen that jealousies as in facade and they they do block the the heats absolutely sun's radiation so that doesn't transfer into the building and in cases of that being that open area will block the wind when it's too strong that's actually important and some buildings have all louvers in them and if it's all open people are sitting and trying to grab the paper on their desk you have to be able to control the directional wind flow as well yeah that is comfortable and not oh my goodness shut that window and then it gets hot you know well let's take a look at the the next slide and we oh this is beautiful yeah so it's yeah here's another home obviously a luxury home a little more upscale but you can see the height of the louvers in it it's open air it's got natural fan ventilation for those days that are hot there's no air conditioning whatsoever you can see the little flat screen TV and then fireplace to the right and it's got a sliding door system so this is really indoor outdoor living which a lot of people try to strive for because it this is pretty much aside from the farm which is very low voltage I mean DC you're not chewing up a lot of energy but you're comfortable in the home and quite happy with it yeah we have suing fans in our new energy code yeah so suing plan plus great cross route ventilation moving a little air across the body with some evaporation you feel great you know kind of really hot days it's a different story but we'll get into that right and yep and on that cherry note we need to take a break this is not cold green this is Martin this spang human architecture I believe is the name of his program I guess Sean Mosley of breezeway we will be back in a minute hello this is Martin this spang I want to get you get excited about my new show which is humane architecture for Hawaii and beyond we're going to broadcast on Tuesdays 5 p.m. here on think tank Hawaii my name is Richard Emory and I host condo and cider we talk about issues facing the condo association throughout Hawaii and talk about solutions when you think about it about one-third of our population lives in some form of common interest real estate we broadcast every Thursday at 3 p.m. please to end tune in and thank you aloha aloha I'm kawi Lucas host of Hawaii is my mainland here on think tank Hawaii every Friday at 3 p.m. we address issues of importance for those of us who live here on the most isolated landmass on the planet please come join me Fridays at 3 p.m. mahalo aloha my name is reg baker and I'm the host of business in Hawaii with reg baker we're a show of the broadcast live every Thursday from 2 to 230 we highlight success stories in Hawaii of both businesses and individuals we learn their secrets to success which is always valuable I hope to see you on our next show aloha good afternoon again Howard wig human architecture I'm sitting in for Martin the Spang and my guest is Sean Mosley territorial manager for breezeway I'm thinking I shouldn't say jealousy windows I should say louvert windows that's correct yeah jealousy louvered windows and we made the distinction first part between the old jealousies that don't do so good and the new ones and look at this Sean we are in the factory in our factory that's for sure yeah but you give us a little walkthrough of okay so if you look over here right there is the raw extrusions that we bring in basically everything is assembled and made to order here in our factory in halava you can see that there's no air conditioning it's a high ceiling factory the venting is also louvers as well and fans everything is made to order I don't like the word custom because it makes people scared of the expense in this case we just every house is different in Hawaii all the concrete structures are different so we just cut everything the size make them if you've got five different size windows we can make five different size windows and you just see in the raw extrusions in the factory off to the right over there you can see this is where they're doing the cutting of the long extrusions that we bring in there's other yellow round circular guy there is the punch press where we punch the holes and handles for everything so from start to finish aside from extruding the raw aluminum everything is handcrafted and handmade here in the valley those guys must work rather fast yep yep the nice part too is it means we stock all of the parts so something breaks you're not waiting four weeks from good place good point yeah you can call us up and there's something to fix a bit and I think the next slide we're gonna get some detail about how the parts go together here yeah oh we there's the stronghold system so this is a louver window that we don't recommend you try this at home because if you're standing on this window and you had a jealousy the glass would have broken by now into a bunch of big shards or as my children like to sometimes do it they want to crawl up the glass thinking it's a ladder well with our glass and the louvers we have the stronghold where we temper the glass and the tempering actually cooks the glass again you have initially float glass is which what breaks in the shards and that's what you can cut and buy from you know the local hardware store and fit to size tempered glass is cut to size and then cooked in an oven which is hiding behind your back there which can kind of seem the orange a little bit the tempered glass increases the strength so that the dead load weight allows up to 185 pounds or in a float glass you'd have maybe 75 pounds and it'll break away on you when it's closed you have an impact weight of about 360 pounds so it actually acts as a guard you know let me interject there in terms of the building codes we're looking more and more at hurricane resistant correct yeah and because we know that it's not if it's when it's gonna hit us with with global warming so we're trying to ensure we know that there's gonna be these objects flow just roaring through and hitting yep and the worst thing you can imagine is hitting a say a two by four yep hitting a window yeah yeah because all the glass very important I didn't go at you I mean the hurricane windows are not cheap they usually laminate a glass with a louver you can't do laminate because it's a round blade but we actually have tested our louver for hurricane standards you have three elements of a hurricane stand and you have wad water wind and impact now if a two by four hits a tempered piece of glass it's gonna break so there are hurricane screens that we place insect screens and serve the purpose of an insect screen but also serve the purpose of hurricane and also security yeah so that you have impact resistance you have water resistance and you have air resistance you can achieve that while getting full ventilation like a would have offered yeah it's called the disaster relief and it's coming to building codes near near us what in the world so so what you're seeing here is the stronghold system put together so on the far right of the screen you're seeing the hole in that blade so what we do is we take the glass blade and we drill a hole in it first then we wash the blade and run it through the tempering oven and that blade seats inside the clip and you see that pin that's got a little dotted line that goes through the clip and through the blade and secures to the other side and then when it goes together it locks the blade in what that means is you cannot remove that blade without removing that pin or breaking the glass we designed this specifically for high rise elevations because we don't want blades falling down 20 stories or somebody taking things out the side effect has been as a security window in so many terms and we don't sell it as a security window but it does increase security in the home because you can't just pluck the blade out from the outside you'd actually have to get at those pins and remove each one or break the glass at that point so what you have here is a much safer window for sheer faces and elevations first story and so forth it sounds like breaking the glass would be a bit of a chore it depends breaking tempered glass there's different ways to do it but it's probably best not to reveal that in public. Basically when you're using tempered glass and you're gonna use the stronghold if you have a requirement for egress where you need to get out in case of a fire you would not use that window in that scenario yeah because you wouldn't have part of the definition of egress is no special tools required yeah and that's why dialysis have been allowed to be used so long if you use a pin in there you're gonna have to have a tool or the components to get it out so you're gonna want to make sure that if in a bedroom or somewhere where egress is required that you're using a window that meets egress requirements absolutely safety first yep I sit next and the what you build a cold console I sit next to the deputy fire chief so yeah very I don't want to mess with those guys yeah they do they work hard enough and have many friends in the department mm-hmm so what else do we have in the way of slides this looks like a beautiful residential setting here yeah so what's neat about this house is all the blades that you see are actually aluminum blades and when that house closes up it gets very dark but when it opens you can see there's only one light on above the sliding door and there's one on the picture for the artwork but everything else is naturally lit and that whole place is breathing I mean so much so that they close the door because there's too much air the benefit of aluminum is total blackout if you say you have an entertainment room and you want to get it dark turn the air out and watch movies all day you can do that and when you open it the aluminum actually reflects good light so it brings in sometimes more than the glass because the glass would absorb the light and when when they're open there's that and the windows there's something called daylighting correct and as opposed to artificial lighting correct and we homo sapiens are about 200,000 years old yeah and we didn't get artificial light until 130 years ago but the mass of people didn't get it until 70 80 years ago so our human eyes and our DNA are completely adapted to daylight we perform better when we perform under daylight so you're letting that in there yeah there's a few slides if we can just kind of roll through a couple I can touch on what you're seeing in that so over here on the top left you have a power louver and you have a manual louver on the right side and that's all natural daylighting that power louver actually integrates with the building management system where when it gets a certain temperature it opens up and allows the heat out to keep the place cool before the air conditioning might kick in if you don't mind going in the next slide so here's all naturally daylight that's an indoor pool this house is actually up in my kiki area and you can see a lot of concern with people with pools and windows is the balustrade requirements that nobody wants to run into when they'll get hurt well obviously all that glass is tempered tempered is often called safety glass so you you know if you get out and you slip and you fall into it it will break into little tiny pieces like a windshield and the worst you'll get is a scratch I would guess but you won't have these big shards coming at you you can see a couple lights on there around the pool but not much the rest is all natural this is a full house this one is actually in New Zealand I believe could be Australia but you can see louvers all the way around you've got tin roofs on the top very modern classic architecture between the two you've got an outdoor pool you got some balustrading for the pool rail there obviously that house is not difficult to live in it's probably very comfortable when you're inside and the lighting is that minimum and it's you know afternoon and could we go back about three slides to yeah yeah I want to talk about controls because the again the building energy code can requires controls controls controls yeah including daylighting controls yeah there's a whole again in this code here there's a whole daylighting section yeah and so I'm intrigued by by that slide in your you had you use controls to shut the windows and turn on the AC because if you don't have controls people if you have a seat people are going to turn it on right in the school or office there's a lot of just let it run there's a lot of different control types like right here for example this is our head office in Australia the windows are all tied into the building management system and the air conditioning as well and you know you have different levels of control options whether you want it to just control airflow and cooling or lighting or even there's control systems that do condensation and humidity based on human you know that factor the level of controls is dependent on the level of engineering and design of it our basic power louver that we have a switch called the activate controls the room based on temperature and timing and we'll open and close based on that if you want to step up into lighting and daylighting then you're getting into a little bit more of a sophisticated system which in a commercial facility would be beneficial like if you go right here Sinclair library and at UH this is unique place because this is a mixed mode library in this case this is the little study room over there all the windows actually on the interior fixed all the louvers on the exterior are solar shades and the louvers on the top are fully operational and the air conditioning system is above that lattice work so should the power go out they have air ventilation there too and you can see all of the solar saline sorry solar shading that is accomplished by having those blades at the right fixed position interesting thing about the position is we had to find one where pigeons wouldn't roost classic Hawaii problem of course but you can see all in the upper part of the louvers you can see the air conditioning ducting and the mechanical systems running through so in that case the daylighting is all LED this is a online I this is the line elementary and you actually this is a classic school room example of a mixed mode you can see the air conditioning system running in the middle you have LED solar tubes down the center and then you have louvers on the sides with security windows on the outside for hurricane impact and so forth so you have a secure facility naturally ventilate ventilated facility and one if it gets too hot can be cooled down and it's kind of very low electrical load on the building we've actually found with stuff like that you your electrical load usually goes down 4850 percent and again if the AC is controlled yeah right by sensors yeah the two work I mean you you set the benchmark of humidity or you set the benchmark of temperature and you say okay now the window opens first and the AC so goes and then it cools the room down so the AC works less hard and the compressor works less hard reducing the energy load it may still be running but the ventilation is not going out versus being stuck inside and the AC have to process the heat yeah and on that very very cheery note and that extremely energy efficient note we are already at our close this is Martin the Spang substitute Howard Whig for humane architecture with my guest Sean Mosley territorial manager of breezeway thank you so much for being with us Sean thank you for having me Howard I appreciate it thank you Martin
