 Good afternoon from me. I'm very glad to be here the first time in Ireland and I enjoyed very much And I hope I can tell you some experience of our German efforts in energy efficiency First I want to tell you about Dana the German energy agency Deutsche Energie Agentur. It is a private corporation established about ten years ago in Berlin about 150 employees and It is a private company, but shareholders are 50% the German state and 26% the KW bank that is the state promotional bank Which provides the financial promotion for the projects in Germany tasks are obtain the lasting improvements in saving energy and more energy efficient use and of course The promotion of the renewable energy in all sectors The targets for the energy consumption energy concept in Germany is the same as in Ireland, I think 20% primary energy demand Saving till 2020 and Establish a nearly Climate neutral Building stock till 2050 The primary energy demand is very ambitious. It shall be reduced till 2050 about 80% We have to do a lot of efforts to reach this and the retrofit rate is as in Ireland about 1% now in Germany 0.9 to 1% and that is not enough to reach to reach these ambitious targets it Shall be 2% but better is to set the target a bit higher than we can reach the point and Therefore we are setting a roadmap to reach these point and we see it is not very easy To get this target the situation in Germany is Not very good the building stock needs too much energy The German energy Performance Ordinance is Says how much energy the buildings are allowed to need and it is about 80 Kilowatt hours per square meter per year and a lot of a lot of the building stock needs more than this The average in the residential buildings in Germany is about 225 Kilowatt hours per square meter and year and that's that must be reduced Very quickly Here I show you how the history of the Efforts in Germany for the for the energy Saving ordinance were made it started in the 70 years 77 after the oil crisis the first heat saving ordinance was made in Germany and every few ever few years the requirements are getting stronger and Now we are at the point. Oh Yeah Where's the pointer this one? Yes? Well now we are here at this point. This is a Slightly elder graphic and this shows the stairs from the Official requirements by law and it's going down and down in the future 2012 a new Ordinance will be made and it's going down a bit and in the end We reach the aims of the EPVD and I think this will be the end of this staircase It is not Useful and it's not necessary to go more down to to make more a stronger requirements for the energy efficiency and These these line is the every average lines of the new buildings Which are built which are a bit lower than these steps, but not very much and this line are these are the pilot project which are built and developed over the years and the minimal or low energy houses Were in the 80s and 90s built in Germany and then the three liter houses Which three liter oil means means 30 kilowatts per square meter and now we are developing the Zero emission houses or the plus energy houses and we are having a model project which Contains 40 very ambitious Refurbishments and new residential buildings Which shall be planned? until now it started to 2011 and then show how to make this aim of the EPVD in the future That's our program in Germany how we can Put this into the market first as I mentioned the ordinances the legal requirements We work together with the German ministries, especially the ministry for housing and of course with the KFW Bank the promotional Bank which provides the financial promotion and these financial promotion there are a lot of programs, but the main programs is energy efficient Building of new houses and energy efficient retrofit and the system works The people get a loan And the loan is restricted until 75,000 euros per Dwelling or poor apartment After the retrofit if the retrofit is successful and proved by an expert Then is a grant Given to the people and the grant is about five till twelve point five percent of this loan the people don't have to the owners don't have to pay them back and This is a very good Grant and if you if the people have Take part in a model project from Dana they get 20 percent grant and Now we are at the third column The market instruments it is very important to get it into the market and it is not so easy as We thought ten years ago it's a lot of information necessary and We do pilot projects to show how it works and to show that it is possible and that it is economical feasible What has been achieved with these three columns First the model project the pilot project in Germany we started them 2003 2004 and till now we have 400 residential houses and about 100 non residential houses mostly schools in the refurbishment some of them are ready and We are evaluating the data which we get from these houses This is a long process. It is during a long time and Because the building needs time and then getting the data needs time the evaluation and we Evaluate the consumption of energy three years after the refurbishment so that we can see is the aim achieved the is the Energy saving reached as it was planned once and this process is not ready We have these evaluation about at the beginning of 2012 of the first about 200 ready refurbished residential buildings and We hope it won't worse and it won't be worse these these datas But I tell you later about the economical evaluation Well, the system works so we make these pilot product projects set standards which we developed together with the Ministers ministry for housing and other experts in Germany and Try it in the pilot projects then if it if they are Done in in the in the practice the KfW Bank takes these standards and Takes it as the normal promotional final financial promotional program and The standards in Germany are in the way that we don't say a certain kilowatt hour per square meter Has to be reached we say The standard for a new building is fixed in the energy performance ordinance and From this standard the buildings has to be better the first programs were 30% better as the energy saving ordinance says and then 50% better and Now we are at a standard new buildings 60% better than the energy saving ordinance and and retrofit It is 45% better and then in 2009 These standards from the pilot projects were then the promotional programs and then they Are getting we're getting the legal requirements in the NF the energy saving ordinance well With this program from the KfW Bank Have been retrofitted a lot of buildings Um But I can say from our view from Dana. It should be more financial program promotional programs in the sum in the year 2011 950 million euro The German state gave to the KfW Bank to promote the pilot projects and To promote energy efficiency in the building sector we think that is much too less it must be five times as high To reach the aims of the government of the climate protection well a very important market instrument is the energy performance certificate This energy performance certificate is necessary for every building for every flat if it is sold or if it is rented new and You'll see at the right hand side the system The system of this there is this this is Oh This shows the primary energy red is bad green is good and There are two arrows the one arrow shows How much energy? Is allowed for a new building to consume and the other one is the situation of the actual building and In energy efficient retrofit the buildings are retrofitted at a standard where they need about 30 kilowatt hours to 50 60 kilowatt hours per square meter and this Certificate was not easy to get into the market But now if a house is sold in the newspaper the advertisement advertisement says The the figures shown here and this is a great success It is it makes clear for the people how good is this building and how much have Have I have to pay for the for the heating? The next one is a label which we are giving for Residential houses first it is developed even for non-residential houses is a certificate how good is my house and Here you see this label and This number here shows how good is the house 55 means that it is 45 percent better than And and new building Well model projects I Talked about this topic and I have I think I have not so much time So I want to proceed to the economic situation But that is Slide which shows the average of the model project the factor 10 is possible You can reduce the energy demand about the factor 10 and that is no big problem We have a lot of buildings which are built in this way and as it was mentioned in other presentations today it is It is very Important to regard the building as one system first the quality of the building envelope Then use renewable energies if you want to get into the standards of the epi BD where nearly do you do your mission is Is obligatory you can't use Oil or gas anymore. It would not work and then of course a good heating system and What is very important for the humidity in the house a ventilation system with heat recovery with heat recovery? That is additional very important well These are standards Which comes from our model project here at the left side Low-energy building a best practice building like our model projects and at the right hand side passive house or dear dear mission nearly dear mission building and that are The building envelope in a very good quality The passive house was developed in Germany from Professor Feist from the passive house Institute together with Swedish experts And it was a very successful building system for new buildings as well as for retrofit We have in the model project a few passive house retrofit which are very good and One of them Is so good that the people the who the tenants of the dwellings don't have to pay any costs of heating and now a Very important topic the financial situation the payback system For both tenants and landlords is There's a situation so that the energy prices are increasing and I think we have a Context that the energy prices will rise in the future Even it is going up and down a bit but The cold rent is not as much increasing as the energy costs and we Evaluated our model projects For the rental housing stock and these are The examples for that We have to divide the costs of a full renovation Which you see at the left-hand side into three parts. This is very important for the landlords for the Calculation of the costs first you have in a retrofit normally improvement of the living value of the value of the dwelling to put Lifts inside or to renew the bathrooms or so on This costs has nothing to do with energy efficiency Then you have to the costs for maintenance and to repair If the facade is not okay if the background is Falling down or so on and these things has to be done in any way in any way and these costs the Landlord has to take from the money. He gets as a cold rent from the from the tenants and Then there are the energy related costs that are the windows and Well, not not not the whole window Just the part of the costs, which is not necessary to repair the window The part of the cost which is necessary to take it to a better standard and these are energy related costs and these three items make the full costs of the renovation and so It is not proven that people say all costs of the building site are related to energy efficiency and It is very important that a lot of costs Provide the conservation of the building and improving the living value and not the energy saving this analyze you must have in mind if you talk about this topic and Well another Thing is the lifetime period and there you'll see the most houses as we have seen before in some slides are built between 1950 and 1980 the situation is in Germany more and in this way because of the world war was very much destroyed and these old buildings Are refurbished in these years About once or twice and now is in a lot of buildings a full renovation necessary and this must be used to put energy Efficiency in this house to renovate it in an energy efficient way and then it is fit for the future and the next renovation cycle is done about 2050-2060 but in this period it needs a very low energy and This is an Evaluation of our model project In the direction of the payback rate We operated in this evaluation with fixed terms energy costs 6.5 cent per kilowatt hour In these calculation has not been Calculated an energy price rising it is with constant energy costs calculated So if the price is rising the situations of the situation is better Then the return of investment the payback is a fix of 25 years and The interest is is fixed with 4.6 percent nowadays is better, but it's the average and There you see the columns that are the different standards which Were reached in the pilot project enough is the Is Now the requirement for a new building The efficiency house 100 is a hundred percent of the Energy Saving ordinance is nearly the same and this is 15 percent better 30 percent better 45 percent better and The columns are the necessary rent increase for the costs of the landlord Scrameter and The red columns are the achieved energy savings of the tenant So this different difference is good for both In these cases where this gray column is Lower than the red one It is It is Good for the tenant and good for the landlord and you see the difference is getting closer and in this Energy standard 55 the costs of the refurbishment is More than the energy savings and this is the point the financial support from the financial Promotion from the state is necessary. So we say Houses with a very low interest of Refurbishment a very low standard Must not be Promoted by the by the state bank But to do very deep retrofit it is necessary to support and Important for the tenant is this The warm rent Must not increase You see the part of the cold rent Unrefurbished is lower in after refurbishment is of course higher But the difference of the cost for heating and warm water is there Not so much and the model project has showed it was not necessary to increase the warm rent for the people Well, I don't know if I have to time I I see I have no time To show some examples Then you can read it. I think in I have a lot of projects and you can read it in the PDF if you'd like to and I thank you very much and Looking forward to the discussion
