SANIERUNGS-LÖSUNGEN
Außenwände
Solid masonry wall
80 mm of internal insulation was added to the wall. Sensors are installed in all external walls. In addition to the built-in sensors, some reference sensors are placed inside and outside. The sensors are somewhat focused in the northwest and southeast end of the building. Roof and first floor is not monitored. The built-in sensors measure relative air humidity and temperature in the interface between masonry and insulation to assess the moisture condition in the interface. Additionally, some practical measurements are carried out with Karsten Tube, Troxler and HF. 15 mm of insulation was installed in the window sills to reduce thermal bridges.
The existing external insulation (added in 1976) was removed as part of the renovation process, bringing the external facade back to the original look

Ground floor window
Skylight
The old wooden window has been renovated and reused as the wooden parts were in good condition. However as the building is situated close to the coast in an aggressive environment, the owner has considered to replace with Wood/Alu frames to avoid maintenance externally. The glazing bar has been partially removed making it possible to replace three smaller panes with one larger
Some parts of the window were maintained (e.g. frame)

Drain around the building Water proofing of foundation This was done due to the building being quite moist and smelly
This part of the renovation is not visible when finished, i.e. does not change the expression of the building
As part of renovating the roof a vapour barrier was applied
HVAC
HEIZUNG
LÜFTUNG
The building was heated with electric radiators and electric water heater. This is replaced by floor heating and a heat pump
The new heating system is less visible than the old one. Radiators was not part of the original building, i.e. the building has now a more original expression

As part of the renovation a mechanical ventilation with heat exchanger was installed to ensure a good indoor climate, also in periods with no one using the building. The ventilation was installed with a separate heating coil to make it possible to adjust the heat faster than allowed by the floor heating.

Kosten
The cost of the renovation is not public available. The cost for the energy saving measures is estimated to be about half the total cost.
