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.

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.
