ENERGY SAVING BY ADDING A GLASS-FAÇADE TO A BRICK BUILDING

Summary, in English

When exploring possible energy saving measures for existing buildings different technical solutions should be investigated. In Malmö, Sweden, a 1930s hospital in a park setting has been refurbished with a general sustainability goal. For one of the buildings a glass-façade has been added to an existing 80-year old brick building.

Measurements of relevant temperatures have been made including measurement of the temperature in the cavity, which is about 600 mm wide, between the glass-façade and the brick wall. The measurement period covers outdoor temperatures between -4°C and +18 °C. It can be concluded that the temperature in the air space between the glass and the brick wall is increased compared to the outdoor air temperature, this increase is between +5-20°C during 90% of the time. This means that this solution will reduce the building’s energy needs in several ways as both the transmission losses and the need for heating the ventilation air will be reduced. The energy saving in terms of kWh is also examined.
