2ndSkin, a sustainable renovation concept

The challenge

Sustainability is hot and happening, perhaps most notably in housing. However, the number of new housing development projects is limited. Therefore, a very large part of the current housing stock is left hopelessly energy-inefficient. The potential climate benefit is huge, but unfortunately, this comes with large investments that that have long payback times.

The solution

TU Delft, BIK bouw, Sto Isoned, Itho Daalderop and Kingspan have teamed up to create 2ndSkin®, an innovative renovation concept that improves the energy efficiency of existing homes. By placing modular panels on outside surfaces of the houses, 2ndSkin® keeps all indoor spaces intact. In addition, 2ndSkin® provides multiple options for energy provision and ventilation, while also enabling energy production through solar panels and heating boilers.

In 2017, 2ndSkin® transformed twelve homes into zero carbon homes in cooperation with housing association Waterweg Wonen. Thanks to a smart business model the housing association will get their return on investment without having to raise the rent for the tenants. Waterweg Wonen is now ready to adapt another 180 houses toward a zero carbon economy.

The impact

2ndSkin® improves the energy efficiency of the current housing stock, which reduces greenhouse gas emissions.

EIT Climate-KIC’s role

EIT Climate-KIC’s financial contribution gave partners the much needed faith in the 2ndSkin® pilot. EIT Climate-KIC used the strength of its community to support the start-up of 2ndSKIN® and kickstart its upscale.
