Short description of the pilot project
The municipality intends to built a new preschool. The construction process has progressed so far that it is the latter parts, monitoring and quality assurance that the project is activly involved. Early stages tested in joint discussions with other subprojects. Mountee will supply help with LCC-calculations and evaluation models using the Sveby-criteria. The building is going to fullfill minienergy-houses requirements, 69kwh/m2 and will use environment-criteria for building materials. MountEE will support the evaluation of these criteria.
Process and planning quality
The building follows energy criteria set in the municipalities energy – and climate plan.
Minienergyhouse standard for energy and Basta-standard for building material will be used. The project will help to assure the fullfillment of these criteria in procurement and construction process.
FTX-ventilation systems are being installed and the building is connected to the district heating system and and solar energy production of warm water. A special feature is the cooling-tunnel used to prewarm/precool ventilation air. LCC-calculations have not been used so far but will be introduced by the project
Implementation of service package
Mainly the later parts of the service-package will be used to evaluate the construction process and performance, using the Sveby-model. However even LCC-calculations will be performed and the planning process will be discussed together with the other pilots.
Energy and Utilities
c) Primary energy demand
The targe is 69 kwh/m2. The building is connected to the district heating system powered by renewable fuels. The building has a solar heating system for warm-water production and is going to install a cooling/warming tunnel for ventilation air. The use of LED-light will be evaluated but so far demands have been made only for outdoor lightning.
d) Renewable energy
The building is connected to the district heating system powered by renewable fuels. The building has a solar heating system for warm-water production and is going to install a cooling/warming tunnel for ventilation air.
Health and comfort
A FTX ventilation system will be installed and evaluated. A air-tunnel keeping the ventilation air on 5-8 degrees C will be installed.
Building materials and constructions
References to green building data bases have been made in the procurement. The builder has to fullfill these requirements. Measurements will be taken to evaluate how these requirements are being met. The builder has to use the databases BASTA, MILJÖBEDÖMNING or SUNDA HUS in order to be able to meet these requirements.
Test of special methods
- Sveby-model is used
- LCC-calculations are introduced
- Air – tunnels are tested
