Consumer data are based on information from local energy suppliers and meter readings at the sites. The data were evaluated by the Center for Interdisciplinary Building Technology (ZIG) of the Lucerne University of Applied Sciences (HSLU). ZIG HSLU attests to the accuracy of the analysis.

To allow better comparison of the different sources of energy, heating energy consumption is reported in the form of primary energy and CO2 equivalents. Primary energy is energy contained in the original energy form or source; e.g. mineral oil or natural gas. CO2 equivalents show the amount of greenhouse gas released by energy consumption. These values were calculated using factors according to SIA 2040.
