This paper reviews electricity consumption feedback literature to explore the potential of electricity feedback to affect residential consumers' electricity usage patterns. The review highlights a substantial amount of literature covering the debate over the effectiveness of different feedback criteria to residential customer acceptance and overall conservation and peak demand reduction. Researchers studying the effects of feedback on everyday energy use have observed substantial variation in effect size, both within and between studies. Although researchers still continue to question the types of feedback that are most effective in encouraging conservation and peak load reduction, some trends have emerged. These include that feedback be received as quickly as possible to the time of consumption; be related to a standard; be clear and meaningful and where possible both direct and indirect feedback be customised to the customer. In general, the literature finds that feedback can reduce electricity consumption in homes by 5 to 20 percent, but that significant gaps remain in our knowledge of the effectiveness and cost benefit of feedback.

Purpose -Buildings, which account for approximately half of all annual energy and greenhouse gas emissions, are an important target area for any strategy addressing climate change. Whilst new commercial buildings increasingly address sustainability considerations, incorporating green technology in the refurbishment process of older buildings presents many technical, financial and social challenges. This paper aims to explore the social dimension, focusing on the perspectives of commercial office building tenants. Design/methodology/approach -Semi-structured in-depth interviews were conducted with seven residents and neighbours of the case-study building undergoing green refurbishment in Melbourne, Australia. Responses were analysed using a thematic approach, identifying categories, themes and patterns. Findings -Commercial property tenants are on a journey to sustainability. Tenants are interested and willing to engage in discussions about sustainability initiatives, but the process, costs and benefits need to be clear.Research limitations/implications -The findings, while limited by non-random sampling and small sample size, highlight that the commercial property market is interested in learning about sustainability in the built environment. Practical implications -The findings highlight the importance of developing a strong business case and transition plan for sustainability in commercial buildings. As sustainable buildings become mainstream, tenants predicted the emergence of a "non-sustainability discount" for residing in buildings without sustainable features. Originality/value -This research offers a beginning point for understanding the difficulty of integrating green technology in older commercial buildings. Tenants currently have limited understandings of technology and potential building performance outcomes, which ultimately could impede the implementation of sustainable initiatives in older buildings.
