 Good afternoon everybody I'll be as quick as I can Call me flash for nothing Tabula IHR energy services. We're a building energy consultancy company. We've grown out of energy action Energy action are the Irish partners in tabula, which is an intelligent energy Europe project Energy action has a history of European research programs come back over 20 years primarily focusing on building energy And fuel poverty long before the acronym be your existed energy action was involved in research in this area We've been very inspirationally co-funded on this project also by Dublin City Council Sustainable energy 30 of Ireland and ESB electric Ireland So what's the purpose of tabula? It aims to create a harmonized structure for European building typologies Focusing mainly on residential buildings though some countries are looking at non residential buildings We were just focusing on residential buildings Typology basically really represents typical buildings So we really wanted to have a look what are the typical Irish buildings in terms of their energy performance There are 13 countries involved the project leaders are from Germany from the Institute vonen und umfeldt based in Darmstadt as Stefan may know them excellent project leaders in The background to it all is basically building typologies existence in various countries sometimes on a national or regional level But what was we what we found when we had our first project meeting was that there was really no common or definitions of public buildings The frequency or the actual numbers of the various building types in different countries really weren't known the first project meeting People were asked to present what have you got in your own country and largely there were huge gaps all over the place and people I actually had very little information that could get their hands on and of course. It's not easy to understand The methodologies that people adopt in different countries and through different languages Everything in tabula is done through English as most European main programs are so most countries. There really are no typologies defined until now What is it building typology? Effectively you're looking at common characteristics of buildings and in this for tabula what we're looking at is energy consumption You're looking at building size classes and also looking at you know terraced houses Detached houses apartments etc. And looking at their energy performance and common characteristics The outputs that you're looking for are particularly for looking for sample buildings to give advice Applications in the form of energy advice to householders to energy consultants to policy makers and To many people in the construction industry while a lot of people here may have an in-depth knowledge of it And some of us know what inside out at this stage. I'm kind of Everything related to how energy performance in buildings the vast majority people out there having to clue and the people most people Who are going to make investments don't really know what the impact of individual measures will have on their houses So this is one of the main aims of tabula to get that information out there It also produces sets of representative buildings so you can model Your whole building stock and look at the impact and simulation of all these refurbishment strategies So kind of feeding into national retrofit programs The expected results from each national partner is to get the typical values for the building energy performance for heat loss through all the various elements and looking at particularly the frequencies again of all the building types in the country and also looking actually the calibration factor between Measured energy use which is the asset rating which is what the be your search is based on and the actual consumption I think there's quite a lot nearly everybody is presenting paybacks based on asset ratings But how does that really represent the way that people are actually Saving energy saving money after works have done So that's more research is needed on that and some of that's been done through tabula Within tabula. We're also looking at the energy saving measures for two stages of refurbishment a standard and advanced Can be decided is being decided for each individual country themselves The main deliverables from tabula will be a national type typology brochure or leaflets So I'll explain that later on and also a building typology web tool more on that and on I'll show you the results of all of that to date The Irish tabula project. So we were presented with a challenge How do you identify typically 25 to 50 national house types? Now some of you out there may say there's hundreds There's thousands of house types. Yes, there are but when tabula we had to try and identify the ones that were most typical Even the German partners have identified. They've restricted it to just 40 kind of building types in Germany So presented with that challenge. We had to model it then for both standard and refurbish and advanced measures of refurbishment and Present an overview of the tabula web tool and for the brochures We were also then looking to model the Irish housing stock So how would we get how what kind of statistics do we have nationally? We had we've a national advisory group in place at the moment with representatives from the government departments Three of the local authorities in Dublin ESB the ESRI and some consultants So which house types how do we actually go about what do we select? What can we use our existing typology information is formal data is very limited if somebody Times people have come to me from academic institutions, you know Can you give me the report which demonstrates all the Irish house types over the ages of residential or commercial? And I'm saying doesn't really exist. You won't find it There's pretty good anecdotal stuff out there Be your assessors have lots of information SCI's quite a lot of information, but there's it's really not all put together in any one place We've sensed this data. It's a bit limited and we don't have a national house condition survey I wish we did they have one in Scotland where they take a snapshot of 3,000 properties every year Across a scientific base from across a range of ages geographical areas And they can get they can pick up the refurbishment levels both from grant related work and Work that's on outside grants So that's something we could look at the be your database is growing But it's not a scientific sample It's slightly skewed as well because a lot of the be your certs are actually as a result of energy efficiency upgrades So they're less representative of the entire stock, but very valuable resource at the same time. We do have it So if you look that you probably won't be able to read this too well But this is the Irish census from 2006 the same census data same table actually will come out for 2011 I noted it when I was filling in my form earlier this year Which is actually for those of you be our assessors will know that the age bands down the left-hand side Don't actually correspond to anything that's relating to energy performance to building regulations So there's a mismatch there that maybe should be looked at for the next census, but again, it's a resource that we have That's the same one just built up in in block format graph format So defining the Irish topology tabulate tabulate on XLS It begs effectively is the master engine in which all the European building typologies are being entered into So what we did was we said Given our own experience We said we would start as the basic basis point from the appendix s which is for the deep methodology Which is the Irish energy rating calculation method SCAI very kindly provided us with the breakdown of the 115,000 be your search that were produced in September 2010 at that stage of the project So appendix s from the deep methodology for those who are not familiar with it down the left-hand side You've all the different types of wall construction and across the top Then the the columns across you have the different age bands and you can see that way the u value Which is the rate of heat loss through the wall changes and for us? This was a very good starting point in which to actually start to identify the main Irish clusters of Irish house types SCI also then gave us the stats at that stage of those 115,000 be your search for existing buildings. Where did they fall? So within that we could look at the same table by percentages And then we could start to rule out various areas because obviously there was no really no timber frame houses built in the You know in the 1930s 40s 50s this kind of thing So we started to piece stuff together to see could we cluster the house types and make sense of it all The outcome of it is that we basically have 29 Irish house types We five Irish apartment types. We're doing some further work on that There's a subtle difference in that in Ireland We have be your search for individual apartments in the whole apartment block where's in nearly all continental Europe They treat the apartment building as a single entity as for building energy rating purposes They also have centralized heating systems main heating systems group heating systems where we end up with most of our apartment buildings We have individual heating systems in flats. So anyway, we're getting around that The buildings from all the EU countries are entered into this tablet out XLS Now I'll just go through some coding stuff and I will flash through this because it's it's kind of nerdy stuff But it's just to let you know that what we've done is as well as analyzing all of these house types in the Irish deep methodology We've also coded them all and put them into this master European Calculation engine So first of all we have five distinctive Irish age bands everything up to 1977 We had no installations was within build any building regulation up to 1977 So we clustered everything together before up to 1977 and similarly from there on it was always based on changes in Basically you values in the building fabric that came as a result of building regulation changes We then built up a whole range of codes for everything that went in in terms of the building construction the wall types I'll should be shot for showing a photograph of a hollow block But the ubiquitous hollow block which is the enemy of Irish energy efficiency is out there folks and we had to code it and We then built up a whole coding structure for again all these Irish house types that we that we developed and identified This is again hollow block half brick front 1977 before 1977 And back to that appendix S table we then kind of cross-referenced it back to that epestic appendix S table of our 29 house types So so I say we ended up with a scatter matrix of Irish house types. This is just a sample of them The whole idea ultimately retabulous you go on to a website You see an array of photographs you say that's very close to my house Click on it and you can go in and get a whole range of energy efficiency information relating to your type It's just getting information out there We did similar coding for all the hot water systems I won't bore you with all the details, but basically we ended up with huge Extended codes of all the Irish heating systems one of the things that was important as we were doing this is we had to You say what's a typical Irish building? What's a typical Irish house say a solid block house from the 1940s? So what kind of heating system does it have? We had to make some decisions when it was built in 1940. It wouldn't have had a central heating system So our typical 1940s house we would say maybe you've had a central heating system that went in the 1970s or 1980s and really hasn't been upgraded much But a very simple control so we to make a lot of these kind of decisions As we went about it So again, I won't go through all of these but we just we coded in the all the entire heating systems as well The next thing we had to look was to identify two stages of improvement and analyze all these 29 house types for two stages of improvement So our first stage was largely based on SEI's kind of better energy homes program We've added in on top of that for example replacing of wooden floors where possible You find in the no flowers suspended wooden floors, particularly in the greater Dublin area houses built in the 50s and 60s And also windows for example, which wouldn't be part of better energy homes or say cylinder insulation Then our stage two which was advanced measures here We were now going to basically get all the building fabric up to the 2011 building regulation standards and starting to introduce renewable technologies heat pumps and and and solar thermal as well So for our friend 29 types in terms of the deep analysis, we were basically bringing them Through the second stage mostly kind of somewhere between a be a b1 and an a3 rating So what's the common coding process in tablet? Basically what we did was we entered all the building types into tablet xls all the heating system types into tablet xls All the standard and advanced improvement measures went in as well This enables basically all of the systems to be analyzed in this come through a common European methodology in this common tabula web tool So what does it look like? It is in development stage at the moment. It will be ready first of November is the launch date But within this you can basically click on your Irish house types and get full details on your Irish house type You can select your Polish buildings. You can select check buildings or whatever country you wish You then select on your heating system And you have a whole range of options all the variants that we've entered in for the Irish heating systems And then you you get a whole there's a whole plethora of calculation data behind this here They kind of it's provided for the three stages of refurbishment in terms of energy needed for heating You then get the energy balance statement again for this particular combination of building and heating system in its existing state The same data again is then produced through the web tools showing it in for the standard refurbishment measures You can get again There's bundles more information there in terms of the details of the heating system for the proposed for standard and advanced measures and There is a whole range of calculation data deep into in in in the web tool but it is there particularly for researchers and and and Those who are interested in those inner workings and all of this will actually be within what's called the standard version of the web To there will be even an advanced version of the web to which goes into deeper detail So there's plenty of stuff if anyone is for researchers There's plenty of work there to keep them busy for a long time if they want to when this goes live We've also produced national each country is required to produce national brochures and this idea is to produce straightforward Either paper electronic brochures that can be got out to the to the mass public so that they can understand what this is all about This is an example of of a brochure we have for a 1970s house in rural Ireland with cavity wall construction What we've done in all of the brochures is we show that the house in its existing state with the first stage of refurbishment and the Second stage of refurbishment you'll see that the costs Associated with the refurbishment measures the improvement in the obviously the technical performance of the property The paybacks associated with those refurbishment measures the energy saved in the co2 saved Sections are shown of wall construction and roof construction again Many of you here in the room will say I sure I know all that stuff already But it it's that standard householder who really is coming to this for the first time Last year I was in a house of a guy in Malahide had a very nice Detached bungalow built in the late 1960s. He'd very good double glazing and he had very telling me very proudly of all the work He'd done on his floor He'd got external wall insulation done. He had his attic insulation the 300 millimeters of insulation And so he was telling me how proud he was he was going to get his house to really high standard So as I was finishing the survey, I said, where's your boiler went outside boilers 20 year old boiler and he said my Plumber says geez don't change that boy. It's the best thing. You know, they don't make them like they used to So I knew when I was going to do the be your sir I said I'm gonna have to break this to him very gently So I had to call him up and say listen You've really improved an awful lot, but you're now up to a D1 rating Well, the guy was going I've just spent 15 grand and I'm at a D1 rating He was on I could see his face hitting the floor So I kind of said to me you just have to do the second part of the thing Which is get your boiler change and get your heating controls up great But you know a this kind of brochure for all these different house types will will help get the information out there so we've a whole scatter of them ready and We're moving on shortly to the Department buildings in terms of national statistics The be your database is an excellent resource. I say it's not a scientific sample But we're doing a lot of work with seai to to work with it at the moment to for all for all this Analysis across the different house types to actually look at what are the minimum the maximum and average scores Compared to as we have them from tablet compared to the national Database so it's been a very good learning curve for us and and for seai I Think they've actually had to develop advanced query tools on the national be your system as well in order to answer Some of the queries we've put to them We look in all that work where we're cross referencing this is actually the the residential be your search Which have issued since the 1st of January 2009 needless to say the the the the larger one in green is the existing buildings and You can see here the spread of the be your search for existing buildings again from the 1st of January 2009 again I think it's somewhat skewed by the fact that a lot of be your sorts have actually issued for refurbished buildings, so Under various grant programs So in terms of the next stage for tabula the web tool will be live from the 1st of November, so The address will be on the final slide our brochures will be ready to go out kind of in about six to eight weeks time Not more work will be done on the national statistics and linking tabula into the national be your database And a full scientific report on the entire project with technical details will be available by the end of the year I think we are now Probably nine months from the end of the project and one of the most important things is that Is really that the work on the project? I really ought to continue after the formal three-year program is finished It's this is this is something that really shouldn't just stop at a point in time And I think all of the member all the partner countries involved are saying as as they're get the more work They do on the program the more they have to kind of reiterate and go through lots of iterations because they're getting better information all The time but that's where tabula is right now, and it is a resource I mean it's our role to get the information out there and We'd be delighted to hear from you after today if you've any thoughts on that Thanks very much
