1 Headline District Heating and Cooling + EPBD Implementation via standardization Boris Lubinski Frankfurt am Main AGFW Energy efficiency association for heating, cooling, CHP

2 What is the primary energy approach / holistic approach? Insulation Technical Building Systems energy carrier primary energy demand (kwhpe/m² a) subject of EPBD implementation national regulation page 2

3 primary energy factors of energy carriers Energy carrier f Pnren f Pren f Ptot f CO2 1 solid 1,1 0 1, fossil fuels liquid 1,1 0 1, gaseous 1,1 0 1, solid 0,2 1 1, bio fuels liquid 0,5 1 1, gaseous 0,4 1 1, waste residual fuel 0,2 0 0, fuels from multioutput systems sewage sludge land fill gas mine gas, coke oven gas page 3

4 3 types of primary energy factors A B C A energy source in nature 1 total primary energy B upstream chain of energy supply 2 non-renewable primary energy C consumer area, point of delivery 3 renewable primary energy 4 non-renewable infrastructure embedded energy 5 renewable infrastructure embedded energy 6 non-renewable energy to extract, refine, convert and transport 7 renewable energy to extract, refine, convert and transport 8 delivered non-renewable energy 9 delivered renewable energy f P,tot = f P,nren = f P,ren = f P,tot = f P,nren + f P,ren page 4

5 What is a primary energy factor of district heating? primary energy extract fuel convert heat refine transport distribute upstream chain of fuel DH-System efficiency primary energy factor page 5

6 What is the basic principle of the district energy standard? option 1: use default values 1 Energy carrier f Pnren f Pren f Ptot f CO2 solid fossil fuel 1,7 0 1, liquid fossil fuel 1,6 0 1, heat from boilers a gaseous fossil fuel 1,5 0 1, solid bio fuel 0,4 1,4 1, liquid bio fuel 0,7 1,4 2, gaseous bio fuel 0,6 1,4 2, solid fossil fuel 0,8 0 0, liquid fossil fuel 0,7 0 0, gaseous fossil fuel 0,7 0 0, heat from CHP a solid bio fuel 0 2,0 1, liquid bio fuel 0 2,4 1, gaseous bio fuel 0 2,4 1, nuclear power plant 0,6 0,0 0, waste heat from b industrial process process-related component district heating component + process-related component 0,4 0 0, waste-toenergy incl. CHP 0,1 0 0, without CHP 0,2 0 0, environmental heat (geo-, aero- and hydrothermal) a b Values are conservative and calculatedincluding losses of a distribution system. Values are based on conventions. option 2: calculate with system specific data page 6

7 What is the basic principle of the calculation? district heating system as a black box primary energy heat heat system boundary primary energy factor = primary energy delivered heat page 7

8 The energy performance of a building shall ( ) include an energy performance indicator and a numeric indicator of primary energy use, based on primary energy factors per energy carrier (EPBD Annex 1) efficient district heating and cooling means a district heating or cooling system using at least 50% renewable energy, 50% waste heat, 75% cogenerated heat or 50% of a combination of such energy and heat (EED article 2 No.41) CERTIFICATE Central District Heating system of GreenCity operated by EnergyEfficiencyCompany energy performance indicators primary energy factor non-renewable renewable total emission factor f Pnren f Pren f Ptot f CO2 a) 0,72 0,25 0, g/kwh all values are based on NCV a) CO2 emissions excl. fuel upstream chain and other greenhouse gases. energy source indicators Renewable Energy Ratio Waste Heat Ratio Cogenerated Heat Ratio RER WHR CHR 26% 0% 64% The calculation is based on EN :2016 measured energy data 2013, 2014 and Frankfurt, Boris Lubinski page 8
