Meer Met Minder (MMM - More With Less) is a joint initiative from federal government and the construction-, installation- and energy-industry in The Netherlands. MMM is the national approach to energy reduction in the built environment. Its goal is to increase the energy-efficiency of 2.4 million homes and other buildings by 20-30% in 2020. To achieve this goal MMM promotes the creation of a structural market for the reduction of energy usage, by convincing home- and building-owners of the profitability and necessity of the reduction of energy usage and by increasing the commercial opportunities for companies in the construction- and installation-industry.
