Literature review of technologies and energy feedback measures impacting on the reduction of building energy consumption

Abstract

In order to reduce energy consumption in buildings, there are a number of available technologies and measures that can be adopted. Energy feedback measures enable energy end-users (e.g. households) to recognize the need for energy reduction and change their behaviour accordingly. The effects of energy feedback measures have been reported on in most North American and European industrialized countries, though little research has been conducted in Korea. This paper presents case studies of energy feedback measures and their effectiveness on the basis of a literature review of academic papers, technical reports and website sources. Energy feedback measures can be as effective (10-20% reduction rate) as innovative energy systems which require substantial capital investment. In this paper, the design strategy of universal human interfaces is also discussed in support of energy feedback measures.
