In the Netherlands, 27 social housing associations (HLM's) and a group of builders are refurbi-shing 111,000 houses to Net Zero Energy levels. Net Zero Energy means that the house annual-ly produces the same amount of energy that is used for heating, hot water, lights and electric appliances. Remarkably, the refurbishments take only one week; the builder provides a 40-year guarantee on the energy performance and the refurbishments are done without government sub-sidies. The best part is: the people living in these houses are very happy with their refurbished new homes. In 2015, these solutions are also brought to the private market. The deal is the same: A Net Zero Energy makeover, with no additional cost for the homeowner. It sounds too good to be true. How was this achieved and could this be done in France?
