Delivering 15% energy savings to residential development renovation

The project covered a residential area with 30 buildings housing more than 230 families. The customer specified that the main objective was to increase comfort in the homes using energy efficient systems and equipment, thereby reducing heating costs for all tenants in the development.

TA Hydronics met with TF Service AB to develop an in depth understanding of the existing system and together they designed and built a system solution to achieve a fully balanced system through the appropriate use of balancing valves, including the STAD valve and differential pressure controller. Optimum room temperature control was achieved by making use of thermostatic radiator valves, such as the TRV 2. In addition to improvements in the heating system, further efficiency gains were realized through better control of hot drinking water and close cooperation with the pump supplier.

Continuous measurements have shown that not only have the changes increased comfort for the tenants but also significantly cut annual energy consumption by 15%.
