1 Ecofys VII U-Values for Better Energy Performance of Buildings Quantifying the potential I II III IV & V VI Climate Protection Regulation Cost Effectiveness Enlarged EU Price Scenario

2 Key figures from Ecofys studies 40% Energy 270 billions/y 3.3 millions barrels/d 460 millions tons CO 2 /y jobs (based on Eurima estimate) Energy price ref: 70$/barrel Trias Energetica "the most sustainable energy is saved energy" 1st: minimise energy loss 2nd: use renewable energy sources 3rd: efficient use of fossil energy sources 1 /

3 Objectives of the study TO DEFINE the optimum U-values base on economic criteria, and environmental criteria, for all countries in Europe. TO INVESTIGATE whether there is room for improvement in reconsidering national requirements (U-values) for building components. TO IDENTIFY the impact of insulation on cooling energy demand in hot climate regions. Starting point EPBD Energy Performance of Buildings Directive EPBD whole building energy performance National or regional whole building requirements Energy performance requirement per building component in practice + U-values either as design criteria or component requirement Economic optimum Environmental goals

4 U-value - coefficient of heat transmission Watt/m 2.K low U-value = low energy transfer Climate conditions CDD, or outdoor t.d > 18.3 C HDD, or outdoor t.d < 15 C

5 U-value - coefficient of heat transmission Insulation & cooling demand in Seville ENERGY DEMAND FOR COOLING - SEVILLE SFH; standard package: wall 0,6 / roof 0,5 / floor 0,5 Wm 2 K 60 kwh/m 2 a reference no shading high int.gains no night vent. low thermal mass without insulation with insulation

6 U-values - economic optimum Economical parameters: Energy mix Energy price scenario WEO 2006 Peak Price (oil: $70 / barrel) Investment costs & Interest rate Today: > $98 Energy performance of existing buildings stock Residential buildings: Single & Multi Family House Climatic conditions for 100 cities characterized by HDD and CDD Life cycle costing over a period of 30 years U-values - climate change To limit temperature increase below 2 C vs. pre-industrialized time, the IPCC reports tell us that global GHG emissions should decrease by 50% by 2050, compared to 1990 In this perspective, EU commitment is to reduce GHG emissions by 60% to 80% in 2050 compared to 1990 Buildings, the highest energy consumer the most cost effective CO 2 mitigation measure (Mc Kinsey), with technical solutions available, should contribute above average. It has been assumed that building contribution should be a reduction of 85% of GHG emissions by 2050 compared to 1990

7 Savings from heating and cooling for one element of the construction Costs + Insulation thickness* Energy cost cooling + heating = Costs - A negative cost represents a SAVING *Indication of the thermal performance of the element. Linear investment for one element of the construction Costs + Investment costs Insulation thickness Total costs cooling heating Costs - A negative cost represents a SAVING Energy cost

U-value -low for roof exist.required. U-value -high for roof 0,20 0,15 0,10 0,05 0, HDD 10 /

10 How blue are U? Present U-values U-values based on WEO2006 price < 0,14 W/m²K >0,59 W/m²K U-values based on peak-price U-values comparison 0,6 U values STOCKHOLM WEO 2006 Peak price Post Kyoto Buildings reg U values AMSTERDAM WEO 2006 Peak price Post Kyoto Buildings reg 0,5 0,6 0,4 0,5 0,3 0,4 0,3 0,2 0,2 0,1 0,1 0 Wall Roof Floor 0 Wall Roof Floor U values WARSAW WEO 2006 Peak price Post Kyoto Buildings reg U values SEVILLA WEO 2006 Peak price Post Kyoto Buildings reg 1,4 0,6 1,2 0,5 1 0,4 0,8 0,3 0,6 0,2 0,4 0,1 0,2 0 Wall Roof Floor 0 Wall Roof Floor

11 Conclusions (1/2) In 2007, most requirements for U-values for wall, roof and floor in new buildings are far from the economic optimum. This means that cash is being wasted for households as well as for society U-values recommended in the study are valid for new as well as for existing buildings. While regulations for new buildings are changing, not much is happening yet for existing buildings. From cost optimum to U-values EXISTING HOUSING STOCK Costs + Present NEW BUILDING REQUIRE- MENTS More comfort More sustainable U-value? Minimum BEST PRACTICE* STATE of the ART Example 1,00 0,70 0,55 0,40 0,30 0,20 0,15 0,12 *Based on oil price study hypothesis

12 Conclusions (2/2) Almost identical recommended U-values, whether calculated base in cost effectiveness or post Kyoto target. If we want to meet our environmental objectives by 2050, with milestones in 2020, we better start NOW! Insulation (especially roof and wall) reduces energy demand for cooling of residential buildings, in Southern and Central Europe. Much is to be done in these warm climate regions. THANK YOU!
