Solar energy

The new co-operation started on spring 2016 with Koillis-Satakunnan Sähkö Oy (electricity company operating on 5 municipality areas in western Finland). First steps were to mount solar energy plants to company office buildings, with real time monitoring systems of course. The co-operation in solar energy included turnkey options for electricity company customers.


e-buildings is working with ongoing project to monitor and optimise energy consumption in commercial buildings. These energy efficiency and management systems have improved conditions of the buildings and therefore lead to more satisfied end-user customers.
