Abstract [en]

The European Parliament Buildings Directive (EPBD) obliges Sweden to develop plans to

enhance the amount of NZEB. Define what NZEB for them exactly constitutes - technical

definitions and system boundaries for energy performance calculations. The National Board

of Housing, Building and Planning in Sweden has received an assignment from the Swedish

government to propose the definition and quantitative approach on energy requirements for

NZEB. NBHBP suggest the system boundary should be the delivered (bought) energy. The

delivered energy divide into two different energy form. The set system boundary to calculate

the specific energy performance with the introduced weighted factor. Makes it possible to

compensate the specific energy performance by using renewable energy generators on site.

The risk is inefficient buildings can use renewable energy technologies on site to compensate

the delivered energy to achieve the 80 kWh/m2, year (the proposed energy requirements for

NZEB). This results to high energy cost along with large investments in renewable

technologies on site, or the need to add fossil fuels to make up the high-energy demand. The

both reference houses Circuitus and Bright Living are NZEB, per the Swedish definition

proposal of NZEB from NBHBP. The most significant difference is Circuitus has better heat

exchanger and building envelope than Bright Living.
