    • Hitherto,
    • Construction industry is regarded as one of the major contributors to climate change.
    • According to the American Institute of Architects, the biggest source of emissions and energy consumption around the globe is the construction industry.
    • ….except China.
    • Hitherto,
    • According to International Investors Group on Climate Change, the cement sector alone accounts for 5% of global man-made CO2 emissions.
    • In heavily urbanized Singapore, where half the total land area is built up, the building sector account for approximately 16% of national CO2 emissions.
    • Singapore Building and Construction Authority’s (BCA) Green Mark Scheme was launched in January 2005.
    • It is a green building rating system that assesses buildings and rates their performance in the areas of energy efficiency, water efficiency, environmental protection, indoor environmental quality and other green initiatives.
    • Well, at least…
    • The scheme to promote the adoption of green building design and technologies that improve energy efficiency and reduce the impact of buildings on the environment.
    • Singapore has set a target of having at least 80% of its buildings attain the BCA Green Mark Certified rating by 2030.
    • The incorporation of green features to achieve Green Mark certification generally leads to higher construction costs.
    • It is important to construct in an environmentally sustainable manner because the construction sector emits significant greenhouse gases.
    • The construction sector is one of the main contributors to GHG emissions in Singapore.
    • Hitherto,
    • According to Fisk and Rosenfeld (1998) buildings with good overall environmental quality can reduce the rate of respiratory disease, allergy, asthma, sick building symptoms, and enhance worker performance.
    • $ But, most of them are still more concerned about economic performance.
    • Urban Ecology Australia (2007) define green buildings must make best use of the sun, wind and rainfall to help supply the energy and water needs of occupants.
    • Cost of buildings environmental friendly buildings will cost about 5% to 10% percent more! $ $ $ $
    • However, it is also said that green buildings could yield up to 30% savings in energy consumption through green features.
    • Reduce heat absorption, provide more day light, maximize natural ventilation, and use more energy efficient air-conditioning systems and light fittings.
    • Shendler and Udall (2005) argued that a significant portion of the additional costs of a green building derives not from the hard costs of purchasing green systems and materials but rather from the soft costs of design, certification, modeling and consulting.
    • Hitherto,
    • The general research approach Singaporean respondents were requested to base their responses on the new home that they would purchase in the near future.
    • Willingness to pay more for green homes 86.7% of Singaporean have knowledge of environmental sustainability.
    • Willingness to pay more for green homes 28% of them are not willing to pay more and would only buy a green home that costs the same as a non-green traditional home.
    • The statistical analysis revealed that 72% of them are willing to pay more for homes that incorporate green features.
    • Green features that home buyers would pay for public transport accessibility are buildings within walking distance of an MRT station.
    • Buyers also likely to pay more to know that contractors adopted sustainable practices during construction stage.
    • Poon (2004) claim, contractors do not always adopt sustainable practice, as their sites generate a lot of waste because they do not have detailed waste management plan.
    • Hitherto,
    • Third party financing of green features should be considered.
    • funding green features It is recommended to provide affordable low interest loans to end-users so that they can pay for green features by themselves and payoff the loans from the savings achieved from the green features used in the building.
    • Government should also lead by developing highly green public housing with low interest loans to end-users.
    • New York State Energy Research and Development Authority administers approximately 2,700 projects through its New York Energy Smart Scheme that the homeowners who qualify under the scheme can get low-interest loans to include green features into their homes through the New York Energy Smart Loan Program.
    • Homeowners could get up to US$20,000 as unsecured loans payable during a period of up to ten years.
    • Homeowners could get up to US$20,000 as unsecured loans payable during a period of up to ten years. = RM61,000!
    • The participating lenders offer the loans at up to 4% below existing interest rates.
    • The state also offers federal tax incentives to those who install energy efficient equipment and measures into their homes.
    • provide mandatory provisions standards to adhere policy makers and regulators involve ✓ ✓ ✓
    • Legislation
    • Hitherto,
    • Building Control (Environmental Sustainability) Regulations 2008 have mandatory provisions on the minimum environmental sustainability standards that construction projects must adhere to.
    • Policy makers and regulators may need to take into consideration issues.
    • Recommendation that potential home buyers be educated about lifecycle costs instead of focusing merely on upfront costs.
