Thermal and lighting behavior of office buildings in Santiago of Chile

▸ Solar protection, envelope's glazing ratio and glazing type to reduce energy demand. ▸ 288 office cases simulated on TAS to estimate heating and cooling energy demand. ▸ Complete glazed façades are not recommended due to a high cooling energy demand. ▸ Night ventilation is effective to reduce cooling demand in office buildings. ▸ Small windows with solar protection allow better daylighting than larger ones.
