New Case Study: New single family house in Greenland!

A new Swegon Air Academy Building Case Study is a new single family house in Greenland!

Recently, a brand new single family house in Sisimiut in Greenland was constructed as a wooden house typical for Greenland. However, some non-traditional measures were implemented in order to reduce the energy consumption and improve indoor air quality. Assessment of the influence of these measures is essential for their implementation on a wider scale. In particular, functionality of the state of the art ventilation system is of large concern as these systems have not been commonly used for their sensitivity towards the extremely cold climate. A detailed monitoring system was installed in the house. It enables the evaluation of the indoor air quality, as well as building’s energy performance.

The aim of this investigation was to evaluate the performance of the newly constructed house by and compare it with the performance of identical house built in a traditional way by using a computer model. The data obtained from the measurements in the new house were used to verify the model. Significant energy savings and improvements of indoor air quality were found in the new house when compared to the traditional one. Moreover, all the extra measures have a feasible payback time despite high prices of labor and transportation to Greenland.

Results from the investigation of single family house in Greenland

Increasing the insulation layer and using the mechanical ventilation system with heat recovery allows a decrease in the energy consumption for space heating by about 45%. However, the design heat load in the energy-efficient building is only slightly lower than in the standard one. Significant part of the reduced energy consumption comes from the heat recovered in the ventilation system. The investments are also economically justified, especially taking into account the uncertainties concerning future oil prices in Greenland. In both models there is a risk of overheating. In residential buildings it can be mitigated by opening the windows, but in buildings where it is not possible additional counter-measures should be taken.
