As a result of the large amounts of CO2 emissions the built environment produces, it contributes immensely to climate change. Within the strategies developed to reduce anthropogenic CO2 emissions, getting buildings to an energy-neutral level is one of the main priorities. The blueprint for this altered energy-efficient building now seems to be ready: the heavily insulated outer shells of buildings have decreased the demand for energy and the necessary coolness and warmth are induced using low-temperature systems. Whether these changes are enough remains to be seen. The actual, measured energy efficiency of these environmentally friendly buildings turns out to be lower than their theoretical efficiency; they use more energy than was expected up front. This difference can partly be attributed to the increased complexity of and sensitivity to improper use of these buildings. Users simply do not understand them well enough. Improper handling then turns into energy loss. Rebound effects also play a role in the lower levels of energy saving. The rebound effect states that as a result of higher efficiency, energy will relatively be cheaper. Lower energy bills will lead to a more increased use of warming and cooling, or to extra activities – whether or not polluting – outside the building...
