Abstract

Climate change and global warming are major issues in sustainable development, with the building sector being responsible for more than one third of global greenhouse gas emissions, and in many countries being the largest source of these emissions. It is believed today buildings are responsible for more than half of the energy consumption worldwide, significantly contributing with the carbon dioxide emissions they are responsible to the very cause of climate change. The knowledge gap that exists with respect to how emissions from built environments can be reduced and mitigated, how buildings and components can adapt to shifts in global and local climate must be filled (Altomonte 2008). A significant proportion of the energy consumed by the building over its life cycle is the embodied energy in building materials and construction processes. The intergovernmental panel on climate change estimated that around 30% of the base line carbon dioxide emissions in buildings projected for 2020 could be mitigated in a cost-effective way globally, at no or even negative costs, if bioclimatic principles were considered in material selection and construction stages of buildings, thus reducing their embodied energy. There are three major ways to reduce energy consumption: reducing building energy use, replacing fossil fuel with renewable energy, and increasing energy efficiency. Therefore, reducing embodied energy in buildings has come into focus as one of the issues in reduction of carbon dioxide emissions and global warming. Reducing embodied energy of buildings by using bioclimatic principles to achieve optimum embodied energy use can improve energy efficiency, and importantly reduce costs and lifecycle energy use. The paper discusses the use of bioclimatic design techniques to identify criteria that can be used to decrease the embodied energy used in building materials and construction processes. The criteria can assist with developing a model and checklist to apply for an optimum embodied energy of actual building which includes both pre-construction and construction stages.
