Sustainable building services in developing countries: the challenge to find 'best-fit' technologies

摘要

Intelligent energy efficiency technologies in developing countries can be assessed on the basis of best-fit criteria (usable controls for occupants, minimum conflicts in operation, inherently energy efficient, and easy to build, maintain and operate). This article argues that ostensibly energy efficient solutions will not perform as intended unless they are appropriate for the climate, are well detailed, installed and commissioned, and are of a level of complexity that can be understood by managers and users of the building. Relevant low-energy technologies include greywater recycling systems, passive and active thermal storage, and ground-source heat pumps. Successful export of such technologies on a wide scale will depend on developed countries setting an example at home. For low-energy building design to have a lasting momentum, commercial clients and governments on both sides of the economic divide need buildings that broadcast a commitment to proven - rather than theoretical - energy efficiency.
