SBB initiates unique investment in decreasing CO2-emissions by 75%

Extract from pressrelease 2019-02-01


Samhällsbyggnadsbolaget i Norden AB (publ) ("SBB") is investing in a unique project with the aim of reducing energy usage by at least 50%, which together with use of solar energy will decrease CO2 emissions by around 75%. We expect to achieve this with the use of heat pumps and heat recovery from exhaust air and waste water. SBB is currently working in cooperation with the Swedish company Watts2You on developing a solution to enable the operation of heat pumps that produce electricity from solar cells. The electricity produced can also be stored in batteries to meet electricity needs even during the dark hours of the day.

"Sustainability is an integrated part of SBB’s business model. This investment and cooperation with Watts2You in using solar energy modules to achieve a 75% reduction in CO2 emissions is an innovative approach in addressing one of the greatest challenges facing both the businesses and society," says Ilija Batljan, Founder and CEO of SBB.

"SBB and Watts2You are both focused on sustainability and on finding solutions for climate change challenges. The solar energy modules from Watts2You will enable the buildings to be even more green and energy efficient. The project has the potential to significantly contribute to the transition of the Swedish energy system. Watts2You are proud and happy to be part of this effort," says Lars G. Josefsson, Founder and CEO of Watts2You.
