Buildings consume nearly 40% of all energy use and building construction and demolition generate huge amount of pollutants and wastes. Consequently, buildings and building products need to be more eco-friendly in order to minimize the impact to the environment. Eco-efficiency is one of the many concepts that designers can apply to reduce the environmental impact of designs. Several public agencies and private companies also offer a variety of ecolabels that validate the ecoefficiency of project, company, system or material. The research team integrates the concept of ecoefficiency with food labeling technique to develop a new ecolabeling concept that could potentially improve the communication of building eco-efficiency information at the design stage. The paper also discusses the potential hindrances and conflicts of the proposed ecolabel. The intention of this ecolabel is to convey the information of building design and product eco-efficiency accurately to the designers so that they could reduce the impact of their designs on the environment.
