“…CASBEE, an environmental assessment method for buildings, has become synonymous with the definition of sustainable building and its quality assurance in Japan. Unlike the case of European evaluation systems, the building environmental efficiency (BEE) is addressed in relation not only to the environmental load (L) but also to the quality of the building (Q) (Murakami et al, 2006). Environmental quality (Q) consists of the indoor environment (including acoustics, lighting, thermal comfort and air quality), service quality (including adaptability, flexibility and durability) and outdoor environment.…”

Despite the lack of mandatory thermal requirements in the housing sector, an average Japanese household consumes around one-third of the energy for heating and cooling compared with a UK or German household. Based on a policy analysis and interviews, this paper identifies the concept and policies for sustainable building in Japan considering the characteristics of the building stock and household energy use behaviour. Energy and housing policies are described in terms of regulations, fiscal instruments and labels, and visualized in the context of a market transformation. The research shows that the Japanese policy has a clear preference for market-based instruments. Thermal regulations are limited to large developments only (over 300m2 ) and exclude most of the residential sector. The market transformation is likely to work with appliances, and the Top Runner programme has proved to be an effective policy in making a current market leader a future standard, but the 'scrap and build' housing policy leaves little incentive for energy investments in the building sector; in 24years the resale value of a Japanese home declines to almost zero and the payback time of most environmental measures exceeds the life-cycle of a building. As the implementation of environmental policies is voluntary, and the insulation levels low, the low heating demand per household seem to be due to different behavioural culture. The research concludes the necessity of introducing mandatory thermal regulations in housing in addition to market based instruments in order to gain further savings in the housing sector.

“…Notably, the use of office equipment and lighting often accounts for more than half of a workplace building's overall consumption (Murakami et al, 2006), but much of this consumption is shared, which makes individual actions difficult. Individual energy use is likely to appear insignificant against the potential impact of collaborative reductions (Carrico & Riemer, 2011).…”

Building management systems are designed for energy managers; there are few energy-feedback systems designed to engage staff. A tool, known as e-Genie, was created with the purpose of engaging workplace occupants with energy data and supporting them to take action to reduce energy use. Building on research insights within the field, e-Genie's novel approach encourages users to make plans to meet energy-saving goals, supports discussion and considers social energy behaviours (e.g. discussing energy issues, taking part in campaigns) as well as individual actions. A field-based study of e-Genie indicated that visualizations of energy data were engaging and that the discussion 'Pinboard' was particularly popular. Pre-and post-survey (N = 77) evaluation of users indicated that people were significantly more concerned about energy issues and reported engaging more in social energy behaviour after about two weeks of e-Genie being installed. Concurrently, objective measures of electricity use decreased over the same period, and continued decreasing over subsequent weeks. Indications are that occupant-facing energyfeedback visualizations can be successful in reducing energy use in the workplace; furthermore, supporting social energy behaviour in the workplace is likely to be a useful direction for promoting action.

“…In addition, policies and programmes aimed at building construction, retrofits, and equipment/systems installations are addressed. This paper, which is based on the report by Murakami et al (2006) 1 , gives information on energy consumption and mitigation instruments of greenhouse gas (GHG) emission in Japan. In the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC)/WG4, there is little description for the situation in Japan due to the limited page space of the report.…”

This paper outlines the energy consumption and greenhouse gas emission trends in the residential and commercial sectors in Japan. The results showed that the increase in residential energy consumption in Japan is mainly caused by the widespread use of heating equipment, hot water supply apparatus, and other household electrical appliances. On the other hand, it was indicated that the increase in commercial energy use is mainly due to the increase of the floor area of buildings, particularly hotels, hospitals, and department stores. The paper also describes political measures to promote energy conservation, including the building energy conservation standard, Comprehensive Assessment System for Building Environmental Efficiency, top runner programs, financial incentives, and the dissemination of the Cool Biz concept. Finally, the projections of CO 2 emissions until 2050 are presented.Energy Efficiency
