Buildings itself are renovated or planned to be renovated. New buildings designed according to high energy standards. Willingness to implement new sustainable technologies, examples are:

• Utilization of geothermal energy heating of buildings. Planned to install heatpumpsystem for heating and cooling. Relatively shallow there is 70degress water in this volcanic area (there is a borehole made to find out depth/temperature)
• Planned use of solid biomass-fired heaters (e.g.. straw burning)
• Planned construction of heat recovery ventilation in classrooms
• There is a pound where fish & veggies are cultivated (aquaphonics)
