Powerhouse Telemark is an office building that aims to be carbon positive by using whole life carbon calculations to estimate the carbon that the building’s construction and lifetime use will amount to and measuring that against the energy that the building will produce over its life from renewal solar energy.

Carbon positive house is a prefabricated micro-house that is available in Australia designed by ArchiBlox and claims to be ‘Carbon Positive’ by generating more energy than it takes to build it over its predicted lifespan.

The 200m² single family house is a CO₂-neutral demonstration project. VKR Holding, which is the mother company of VELUX and VELFAC, initiated the construction of eight demonstration houses in a number of European countries following the Active House principle.
