The energy performance of a building (or building efficiency) is expressed in kWh/m2. This metric represents the annual average heating demand per unit of inhabited surface. The lower this value; the higher the efficiency of the building (irrespective of its size). In 2011 the Swiss building stock consumed an average of 92 kWh/m2 .
|Annual average heating demand [kWh/m2]|
|New energy policies||41||21|
|Political measures of the Federal Council||49.5||33|
|Business as usual||57||43|
Each scenario has a series of assumptions, as mentioned previously, one is the rate of refurbishment for buildings depending on their age.
|Buildings constructed before 2011 that will had been refurbished by 2035 or 2050 [%]|
|New energy policies||54||87|
|Political measures of the Federal Council||Not available in the report|
|Business as usual||36||53|
The efficiencies of refurbished/new buildings is also scenario dependent.
|Maximum heating demand for new and refurbished buildings in 2035 and 2050* [W/m2]|
|New energy policies||6.6||6.3||9.9||9.4|
|Political measures of the Federal Council||6.7||6.6||12.7||10.9|
|Business as usual||14.7||12.5||22.1||18.8|
The reader will find more information about assumptions and parameters for the different scenarios in the chapters 188.8.131.52; 184.108.40.206 and 220.127.116.11 of PROGNOS 2012 .
