Building programme

Key facts

The federal and cantonal building programme, financed through a partial earmarking of the CO2 tax, is divided into two parts. Part A encourages renovation of the building envelope and is fully financed by the CO2 tax. Part B supports cantonal programmes promoting renewable energy, waste heat utilisation and building technology in renovations and new buildings, with global contributions from the Confederation. The extent of such global contributions is determined by the individual canton’s promotional efficiency; this is calculated using an estimation model in the cantons’ harmonised model of financial assistance, which compares the energy and CO2 savings made with the incentive costs. The estimation model was devised in 2003 and has been adapted twice since together with the harmonised model.
