Exploring the potential of combining diffuse ceiling and double-skin facade for school renovations

With the aim to offer an alternative renovation concept for schools and thus contribute a better indoor environmental quality reduced energy consumption, system combining diffuse ceiling double-skin facade with existing exhaust ventilation (I-DIFFER) was proposed in previous work by authors. The initial analyses of novel were promising, showing potential 11 % reduction primary consumption compared traditional where insulated, windows replaced balanced installed. Consequently, this further investigates performance I-DIFFER under different boundary conditions using BPS. influence orientation, thermal mass reflectance classroom facade, future climate change, extreme weather conditions, varying occupant densities are studied. results show that can compete approach all investigated orientations but north leads superior southern (SE, S, SW). It found high low is favourable facade. For forecasted climates mild winters hot summers, showed renovation. An equal seen density. study, be confirmed as competitive contributes improving not only efficiency also IEQ schools.
