EPL, the Dutch acronym for Housing Estate Energy Performance, is a measure of the total CO2 emissions associated with such an estate. Since 1999 the so-called ‘EPL monitor’ has been recalibrated at regular intervals for both newbuild estates and renovation projects and in 2008 this exercise was again performed. All in all, the EPL of over 80 newbuild estates and around 50 renovation projects was determined. By means of a written questionnaire it was also investigated what role the regional approach developed by SenterNovem has played in energy-saving on estates over and above the legal obligation. The respondents were satisfied about this support, stating that this approach has often contributed to additional energy savings.
