Comparison of low-energy office buildings in summer using different thermal comfort criteria

Sustainable office buildings supply a high workplace quality (thermal, visual and accoustic comfort) with a low energy consumption. Lean buildings with passive cooling are suited for an economic solution and provide a high thermal comfort even without mechanical cooling or air-conditioning However, a certain room temperature cannot be guaranteed in naturally ventilated buildings as users may influence the energy balance by window opening, internal heat gains or sun control.
