The influence of building regulations on the efficiency and pollution level of the heating system

2010

Vol. 36, nr 3

5-14

In order to adjust Polish regulations to the Energy Performance of Building Directive, new requirements have been introduced to Polish legislation. The well known Polish Standard PN-B-03406:1994 has been replaced by new PN-EN 12831 which raises a lot of controversies especially regarding the final results of heat load calculations based on the described procedures. The paper indicates possible discrepancies in calculation results arising from imprecise guidelines and the consequences of relying on the results gained by the described method. Additionally, later aspects of the system operation and their negative influence on the estimated efficiency level and CO2 emission have been analyzed.
