Building certification Definition • A scheme to assess and disclose the environmental performance of buildings Annual energy consumption Efficiency of equipment Access to public transport Criteria Building orientation Indoor air quality How it works The performance assessment can be based on asset rating and operational rating Building energy certificate indicate the rating of building’s energy performance The certificate is published Strengths of building certification Reduces negative environmental impact, save energy Saves money for building tenants Increases the marketability of green buildings Guides further improvement efficiency Accumulates of data on the environmental performances of building for policy making Requires skilled professionals Upfront administrative Challenges Developers and building owners must pay for building certificate Differences approaches lead to different rating Lack of coordination among certification Cause confusion Limited impacts of voluntary basis Difficult to obtain voluntary participation without incentives Implementing strategies • Complemented with other initiatives such as financial and building codes Supplement Supplement • with supportive measures Build up technological and administrative capacity Require reliable data and continued quality control • A training strategy can be set at the planning strategy • Competent assessors should be ensured before launching a building certification scheme • Data should be collected in a comprehensive administration system and should be monitored • A comprehensive quality-assurance system should be established and related disciplinary procedures should be prepared • A certification scheme should be adapted to changes in policy and legislation Examples Examples Green rating for Integrated habitat Assessment in India • Promotes the use of solar energy • More than 100 buildings already registered for the green rating for integrated habitat certification Green Building Mark in Singapore • Aims to green 80% of building across Singapore by meeting this Standard by 2030 • In the end of 2010, 551 new buildings and 65 existing buildings had been certified Leadership in Energy and Environmental Design in the United States (LEED) • First developed in 1998 • Green building criteria: use of renewable energy, energy efficiency, electrical demand, water consumption, access to public transport etc • Certified buildings were on 25-30% more energy efficient
