New apartments with low energy consumption<br />
Landskrona, Sweden<br />
How does one save energy and CO 2 emissions<br />
in new construction, using straight-forward<br />
solutions and existing technologies?<br />
The goal of the investments – both in new construction and<br />
refurbishment – is to create energy efficient buildings, which,<br />
at the same time, have a good indoor climate. The buildings<br />
must also remain energy efficient and have a good indoor<br />
climate over their entire service-life; this can be achieved<br />
through good management<br />
In Landskrona, in the Southern part of Sweden, the municipal<br />
housing company, AB Landskronahem, erected 35<br />
new rental apartments during 2003-2004. The apartment<br />
layout is quite traditional and the sizes vary between 70 and<br />
115 square meters of usable floor area. When compared to<br />
standard new single family houses, the energy savings in the<br />
35 apartments measure approximately 40-70 kWh per square<br />
metre per year.<br />
No conventional heating is used, that is, no radiators or<br />
under the floor heating systems (the costs saved were invested<br />
in thicker insulation and higher window quality, i.e. triple<br />
glazed with krypton, U-value approx. 0.90 W/m 2 K). This<br />
type of building is called a ‘passive house’. The energy needed<br />
comes from equipment, and is called process energy. There<br />
are mechanical ventilation systems with heat recovery. The<br />
apartments cost no more than conventional ones and the rent<br />
paid is less than for other apartments built during the same<br />
period.<br />
