The word climatizing means adapting the indoor climate to the need of the users - primarily providing comfortable temperature and air quality.
Technical instalations provide active climatizing by heating, cooling and mechanical ventilation.
Passive climatizing uses natural sources such as solar heating, night cooling, and thermic buoyancy for natural ventilation.
The 4D project is provided with mechanical ventilation with heat recovery. The ventilation system is only half the size of an ordinary office ventilation system.
In the winter, heat is recovered from the exhaustion and fresh pre-heated air is blown in behind the radiators. This provides a good comfort at makes regulation of the temperature easy.
The building has a very low need for heating - 2-3 radiators is suitable for a flat. Due to the limited loss of energy through the facade, radiators under the windows is not obligatory for a good comfort. Instead radiators can be placed close the the service duct. The result is short runs for pipes and simple constructions.
The energy efficient building envelope is more expensive than a tradional envelope but the cut-back in installation expenses compensate for this.

| Summer night: Coolness is absorbed by the thermal mass in the concrete construction (no suspended ceilings) |

| Summer day: During the day the construction gives off the coolness absorbed from the night air |
