Method for cost-optimal retrofitting

A two-step methodology that aims to select the cost-optimal solutions for retrofitting of buildings in large-scale renovation process (200-300 dwellings). From a set of different potential combinations of passive elements (e.g., adding different insulation materials with different thickness and/or windows) and active elements (e.g., heat pumps / multi-split air conditioning for heating, cooling and DHW […]

Heat pump system design

The aftercooling concept is an innovative district heating substation for large multi-apartment buildings where the domestic hot water preparation and reheating of the circulation flows are decoupled and obtained in two separate heat exchangers connected in parallel. The primary return temperature flow from the circulation heat exchanger is further aftercooled by the space heating system […]
