Public housing is in need of energy optimisation. That will lead to lower electricity and heating bills, improve indoor climate and be a valuable contribution to the green transition of the Danish society. COWI's method for green screening and energy optimisation of public housing builds on years of experience with innovative projects in energy optimisation, digitalisation and renewable energy sources.
We use the tools PVT-BAT and Smart Autotuning, which use intelligent data about the buildings, the electricity and heating consumption of the housing association, the current interest level, financing, electricity rates etc. to determine which size of solar cells and battery storage can secure the best operating result for the residents.
The method provides an overview of the possibilities of optimising the total energy consumption and climate footprint of the housing association, while ranking possible investments based on their financial and climate advantages.
