Defining the Polish nearly Zero Energy Building (nZEB) renovation standard

Szymon Firląg

Abstract

The paper describes the process of defining the requirements for renovation of single-family residential buildings to the nZEB standard in Polish conditions. According to the survey results the nZEB renovation standard should include only two indicators: energy need for heating QH expressed in kWh/(m2 year) and percentage reduction of the primary, non-renewable energy QP demand. Process of defining the requirements was divided into two stages: calculation of cost-optimal heat transfer coefficients for renovated elements of building envelope, calculation of cost-optimal renovation standard of the two single-family model houses. The analysis was made for three Polish cities (coldest, medium and warmest) and for 5 different energy prices. As an optimizing criterion the minimum cumulative cost was used, calculated for the 30-year time-scale for different variants of renovation.
