We are interested in energy performance calculation tools.
We are a team of HVAC designers, energy and sustainable consultants and auditors.
Every day we are challenged with the question of whether it is possible to be independent of natural gas or other fossil fuels.
Well let's see and calculate together.
We created this site and tools for everyone and we will see if it is possible.
Independent companies, non profit organizations or company with know-how were involved.
Thanks for your effort and enthusiasm.
