Efficiency of equipment

Definition

• A scheme to assess and disclose the environmental performance of buildings

Criteria

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

How it works

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

Upfront administrative

Requires skilled professionals

Developers and building owners must pay for building certificate

Lack of coordination among certification

Differences approaches lead to different rating

Cause confusion

Limited impacts of voluntary basis

• 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

Implementing strategies

• Supplement

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
