“…Besides the traditional building materials, there are also advanced technologies for the building envelope such as advanced wall systems (passive solar walls, lightweight concrete walls, ventilated or double skin walls, walls with latent heat storage), advanced glazing (aerogel glazing, vacuum glazing, switchable reflective glazing, suspended particle devices film, holographic optical elements) and roof systems (ventilated and micro-ventilated roofs, solar reflective/cool roofs, green roofs, photovoltaic roofs) [15]. The traditional thermal insulation materials are vulnerable to humidity and perforations.…”
