Thermal Insulation of Building Envelope for Ecological Conservation

Abstract

Sustainability has been a rising concern for facility projects since the early 1990s. It is conscious that in terms of carbon emissions, energy usage, water use, utilisation of raw materials, waste production and many other factors, construction and operation of buildings have enormous direct and indirect environmental consequences. Increased economy and population will create more and more challenges for the design, construction and operational community to fulfil the newrequirements for infrastructure that are affordable, safe, resilient and sustainable while reducing their environmental impact. The building envelope’s key feature is to offer shelter, safety, solar and thermal control, control of moisture, control of indoor air quality, access to sunshine, and outdoor views, fire resistance, acoustics, cost-effectiveness, and aesthetics. This study seeks to promote awareness on the energy friendly design strategies which economically minimize operational expenditure, while enhancing comfort of the occupants in the building. Thisworkwould allowarchitects, engineers and builders to choose the most efficient or climate-reactive envelope alternative in order to improve thermal environment efficiency of the construction design being proposed.
