The building sector is responsible for more than one third of the emissions within the EU and roughly 75% of the building stock is currently energy inefficient. An estimation also shows that 85-95% will still be standing in 2050. This means that focusing on energy efficient new-build is not enough, we need massive renovation efforts in order to reach our energy and climate targets.
Improve energy efficiency
Offices are typically empty more than they are occupied. When rooms are not in use the ventilation demand is low, however - when the rooms are in use the demand for ventilation is very high.
By making use of these buildling occupancy trends we ‘open the doors’ to excellent energy savings potential. For example, installation of mechanical ventilation with a heat exchanger could recuperate around 90% of the heating/cooling energy in the building. By also choosing the right systems solutions for the mechanical ventilation, further savings can be made.
To take energy savings to the next level, the answer is to demand control the indoor climate. That means monitoring the actual needs in the room, and adapting the airflow, heating and cooling accordingly. In this way, the indoor air quality can be secured in the most efficient way. Studies show this brings energy savings of up to 80% of the fan energy and 40% of the heating and cooling energy.

Optimised water temperature gives lower energy consumption
Water optimisation is a function that is a part of Swegon's WISE-system which takes full control of a building's HVAC-system. The function optimises the inlet water temperature depending on the actual need at room level. The function ensures that the temperature difference is as small as possible between demanded and supplied inlet water temperature which will minimizes the energy required to heat or cool. It reduces the energy use for cooling and heating with up to 15%. For example, 3% energy can be saved for every degree the cooling water temperature is raised and 2,5% energy can be saved for every degree the heating water temperature is lowered.
Because our solutions have a direct and indirect impact on the people and the environment around us Swegon is always developing products and systems that are energy efficient and sustainable.
