Eco­works is a young start-up following the vision, CO2-neutral housing for everyone. The company transforms old residential buildings into net zero energy buildings with a combination of Passive House quality deep refurbishment and photovoltaics on the roof, making for an annual energy and CO2 balance of zero. Similar to the Dutch Energiesprong, ecoworks is working with industrialised, prefabricated roof and façade elements to reduce construction time and costs to a minimum.
