HVAC systems components
The decision for building heating could be hydronic heating systems, radiant heating or air heating. Also ventilation systems with recuperation, cooling and air conditioning systems decisions and components.
The operation of heating, ventilation and air conditioning systems must be combined with each other to reach comfort microclimate conditions.
Building energy sources
The A++ energy perfomance class building produces as much renewable energy as it consumes on average per year. As example, the solar energy collectors, solar glass modules, solar wall, solar roadways, solar landscape lighting, solar and wind hybrid systems could be used.
