ANSWER FOR QUESTION 1

The Green Building Index (GBI) is Malaysia's industry recognised green rating tool

for buildings to promote sustainability in the built environment and raise awareness among

Developers, Architects, Engineers, Planners, Designers, Contractors and the Public about

environmental issues and our responsibility to the future generations.The GBI rating tool

provides an opportunity for developers and building owners to design and construct green,

sustainable buildings that can provide energy savings, water savings, a healthier indoor

environment, better connectivity to public transport and the adoption of recycling and

greenery for their projects and reduce our impact on the environment. The Green Building

Index (GBI) is Malaysia’s industry-recognised green rating tool. The GBI provides an

opportunity for developers and building owners to design and construct green, sustainable

buildings that can provide energy and water savings, a healthier indoor environment, better

connectivity to public transport, the adoption of recycling and greenery and reduction of

environmental impacts. The GBI rates six types of residential and non residential buildings as

Platinum, Gold, Silver or Certified. Buildings certified under the GBI are assessed in six key

criterias such as Energy efficiency, indoor environmental quality, Sustainable site planning

and management, Material and resources, Water efficiency and Innovation

Green building (also known as green construction or sustainable building) refers to a

structure and the using of processes that are environmentally responsible and resource-

efficient throughout a building's life-cycle: from siting to design, construction, operation,

maintenance, renovation, and demolition. In other words, green building design involves

finding the balance between homebuilding and the sustainable environment. This requires

close cooperation of the design team, the architects, the engineers, and the client at all project

stages. The Green Building practice expands and complements the classical building design

concerns of economy, utility, durability, and comfort.

The project that we referred as stated before, Encorp Strand is mixed commercial

development situated 12km northwest of Kuala Lumpur. Located in a fast thriving township

of Kota Damansara, it has a population of over 500,000 living within a ten minute driving

radius. The projects are tackling water conservation and protection through three distinct

activities: ensuring water efficiency of our developments, saving water at construction sites

and preventing pollution through run-offs at sites. With an annual rainfall of 300cm in

Malaysia, there is an opportunity to collect rain for non-drinking purposes. Designs of

commercial buildings incorporate a 30,000 litre rain harvesting tank which channel water for

the use of air-conditioning coolers, landscaping and external cleaning. Malaysians use an

average of 226 litres of water per person per day. This is more than double the usage of

neighbouring countries. To help customers reduce their consumption through installation of

GBI certified low flow sanitary ware which reduce the use of water by half. As GBI gains

traction in Malaysia, more GBI fixtures will be available in the market. Domestic water is

piped in from water mains to each construction site. Water is used for brick laying, tiling,

plastering and domestic use by workers living on site. Our concrete is delivered pre mixed

and requires no additional water. We maintain checks on hose pipes to ensure that water is

not wasted. The project do extract ground water on all our sites which we use for sanitation

and non-drinking purposes. Also do not currently measure amount extracted. Water used in

sanitation is discharged into a septic tank. Although to monitor surface water runoff from

sites by ensuring water leaving our site is free from silt by constructing perimeter drains and

silt traps at our site. Besides that conduct regular maintenance of construction machinery to

avoid oil leaks onto land and ensure emission within permissible standards. Waste from

construction sites can be classed as scheduled, construction or domestic waste. The

subcontractors are required to undertake the removal and safe disposal of chemical and

scheduled waste off site. Construction and domestic waste is removed and disposed of by

licenced contractor. We currently do not weigh the waste removed from our sites. However,

are able to calculate approximate weight of waste removed based on number of trips and

tonnage of waste skip. An estimated 956 tonnes of waste was removed from our Gardens

project in 2011. With an average temperature of 32˚C, a lot of energy is used to keep

buildings cool in Asia. Through incorporating design features and materials, we can reduce

the cost of operating and carbon footprint of our buildings. Designs to orientate buildings to

provide natural sun shading, sky gardens to provide heat insulation, use of low E glass and

maximise shading in open areas help to reduce heat island. Installation of LED light fittings

also allows customers to install energy saving lights and motion sensors.

ANSWER FOR QUESTION 2

Sustainable construction method also has some strategies as the way to achieve it

because it is not a simple and easy way to implement to each of the project team members as

it required many trivial criteria to fulfil. So, here are some strategies that has been

implemented in the project (referred to the above project) as to fulfil those sustainable

construction criteria method :

NO. STRATEGIES DESCRIPTION

1 Procurement Specific procurement strategies to ensure sustainable

construction requirements are addressed.

2Safe working

environment

Maintain zero accidents

Proper site management and give a safety talk.

3 Reduce Turnover Lowest turnover rate benchmarked against industry peers

4 Decent workplace for all Contractor compliance with ILO standards

5 Waste

7 Carbon Map and set reduction targets of carbon from

construction materials from a 2012 baseline

Installation of energy efficiency fixtures in new

developments

Measure and set a reduction carbon emissions from assets

owned

-

8 Biodiversity

All greenfield development undergo biodiversity

assessment by 2016

Biodiversity enhancement plan incorporated into all new

development by 2016

9Indoor Environmental

Quality (EQ)

Methods to ensure indoor environmental quality

measures during construction are managed and executed

properly.

This strategies also implemented in the project as to

achieve good quality performance in indoor air quality,

acoustics, visual, and thermal comfort. These will involve

the use of low volatile organic compound materials,

application of quality air filtration, proper control of air

temperature, movement, and humidity.

Energy Methods to ensure and improve the building’s energy

performance, reduce energy consumed during

construction, and identify opportunities to use renewable

energy sources.

Energy Efficiency (EE) is the way that the project to

achieve its sustainable construction method target which :

- Improve energy consumption by optimising building

orientation

- Minimizing solar heat gain through the building

envelope

- Harvesting natural lighting

- Adopting the best practices in building services

including use of renewable energy

- Ensuring proper testing

- Commissioning and regular maintenance
