Free application that supports the (Flemish) Energy Performance Legislation for Buildings. EPB=software is based on a large number of building and installation characteristics and calculates the U-values, the average insulation level and the E-level (Primary energy consumption) of newly built or renovated residential and non-residential buildings and controls compliance with energy-efficiency and indoor climate requirements. It also checks the compliance with the minimum ventilation requirements for all types of buildings.
EPB-software Vlaanderen 1.0 has been public since March 2006. A French test version was made for the Brussels region and will be made for the Wallon region. Screen Shots
EPBD implementation, Flemish region, primary energy consumption
A large number of manually calculated cases are implemented as automatic tests and compared with the results given by the software.
General knowledge about the (Flemish) Energy Performance Legislation for Buildings (EPB).
Flemish region: for regulatory purposes - All EPB-reporters, architects, building contractors, students, …(1500)
Brussels region: no regulation yet, test phase
Wallon region: no regulation yet, in framework of voluntary actions
EPB-reporters, architects, students, energy agencies, research institutes
Building characteristics: Walls and windows, Thermal mass, Ventilation and Heating zones, Shading, Adjacent non heated spaces.
Installation: Heating (incl. heatpump and external heat supply), Cooling, Humidification, Hot tap water, Lighting, Ventilation system (energy), Auxiliary energy and Thermal and photovoltaic solar energy
Ventilation system (IAQ): Room characteristics, Supply openings or supply rate and Exhaust openings or exhaust rate
All building components need to be defined in a library (characteristics and product-ID). Besides detailed input, a large number of default values are incorporated.
What: E-level, Primary energy consumption, K-level (general insulation level), U-values (component insulation level), Room Ventilation (IAQ), Overheating (only for residential buildings).
Form: GUI, pdf, Energy performance certificate (generated by Flemish energy performance database)
PC (Windows XP/2000), Mac (Mac OS X)
Quite complete energy calculation for newly built or renovated residential and non-residential buildings, a large number of detailed calculations, the application has been tested intensively and by many users, strict conformity with legislation, EPB-software is available free.
The application can be improved with graphical representations. Output module to be further developed.
For free in Flemish region (can be downloaded from web site. Flemish region (version 1.1), Brussels region (test version 0.9), Wallon region (test version 0.9 – in the near future).
