Passivhaus School uses Thorn luminaires

As part of its commitment to meet the EU's target to increase energy efficiency by 20% by 2020, Landskrona Municipality has opened what it claims is the most energy efficient school in Sweden, Emilia School in Häljarp. Not only is the building constructed by a cost-effective, sustainable design solution, but the lighting is equally sustainable.

Emilia School is one of the first educational facilities built using the passive house technique. A passive house is a mechanically ventilated building that, with a highly insulated and air tight building envelope, uses minimal energy for heating - thus reducing its ecological footprint.

The term "passive house" (Passivhaus in German) refers to a set of voluntary criteria for an ultra-low energy use building and was developed by Prof Bo Adamson of Lund University, Sweden, and Dr Wolfgang Feist of the Institute for Housing and the Environment, Germany.

Extremely efficient lighting must be used in order to meet the primary/source energy targets (the total site energy target is <42 kWh/m2/yr), hence Thorn has delivered a total classroom solution, including the use of lighting controls. Among the many luminaires are Optus IV fluorescents, incorporating 35W T16 lamps and whiteboard options.

An outstanding feature of the lighting is the integration of lighting and heating controls. Bo Hall, Thorn sales representative, said: "Normally it is possible to control the intensity, the daylight and the presence in the rooms, but here the lighting also contributes to the heating of the building."

Emilia School principal Lena Johnsson says that everyone appreciates the good lighting and feels comfortable in the environment. She said: "The lighting solution has not yet been used to help heat up the building, but it is just a matter of time. Soon there will be cold nights again."
