- To contribute towards a reduction in demand side energy use in Europe over thecoming decades, a key system that must be put in place, is a method of monitoringenergy usage trends in buildings. A basic premise for such monitoring is, that,across the continent, mandatory building thermal effi ciency standards have notlead to reductions in energy use in line with regulations. Germany, for example,has had building thermal regulations in place since the early 1970’s. Theoreticallythere should have been a 60% reduction in residential sector energy use there overthis time. The reduction has, however, been only 38%1 . A reoccurring problemis that, although applicants for building permits submit plans which include thethermal characteristics of the buildings they plan, compliance is rarely monitoredafterwards by authorities. This has implications for the energy saving initiativesthat have emanated from the EU in the last few years including the EnvironmentalPerformance of Buildings Directive (EPBD). In fact, and this certainly includesbuildings, the IPCC SRES2 states that there is an inadequate ability to capture thepotential for effi ciency improvement and the impacts of effi ciency programs.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- If the trends in energy demand for residential sector space heating seen inSweden from 1970 to 2005 continue, total demand is predicted to fall from52 TWh to 47 TWh by 2050. This fall will occur despite projected increasesin average dwelling size and population size. This is because the unit consumption(kWh/m2) of energy use for space heating continues to fall and itstrajectory will offset increases in demand attributable to increases in averagedwelling size and population size. These figures correspond to a reduction inunit consumption for energy for space heating from 125 kWh/m2 to between60 kWh/m2 and 74 kWh/m2. This fall can be amplified through higherenergy prices and increased energy efficiency, to reduce the total to 37 TWh(60 kWh/m2). However, the price elasticity of demand for energy for heatingin dwellings has been found to be very low (-0.16), which means that improvementsin energy efficiency brought about by direct regulatory intervention andincremental technical breakthroughs are of greater importance.
