GBI vs LEED

Concept meets the needs of the present without compromising the ability of future generations to meet their own needs. the construction process and

occupancy processes that are environmentally responsible and resource

efficient throughout a building's life-cycle from location to design,

construction, operation, maintenance, renovation, and demolition.

Sustainable construction should also:

• Enhance living, working and leisure environments for individuals and communities.
• Consume minimum energy over its life cycle
• Generate minimum waste over its life cycle
• Integrate with the natural environment
• Use renewable resources where possible

Is an environmental rating system for building developed by PAM (Pertubuhan Arkitek Malaysia) and ACEM (Association Consulting Engineers Malaysia)

Its develop specially for the Malaysian Tropical Weather, environmental and environmental context, cultural and social needs

Malaysia first comprehensive rating system for evaluating the environmental design and performance of Malaysia buildings based on

Energy efficiency

Indoor environment Quality

Sustainable Site Planning & Management

Green building (also known as green construction or sustainable building) expands and complements the building design concerns of economy, utility, durability, and comfort.

A Green Building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier space for occupants as compared to conventional buildings.

LEED – Leadership in Energy and Environmental Design

• Administered by the U. S. Green Building Council
• Voluntary, consensus-based system
• the second oldest tool was available in the year 1998 which was Developed by United States Green Building Council (USGBC).
• Up to date, there are 135 countries implementing LEED certification assessment tools.
• Similar to BREEAM, LEED has also been the earliest model that is being adopted and modified accordingly to one countries environment and nature (Reed et al., 2009).

OBJECTIVES OF GREEN BUILDING

STRUCTURE EFFICIENCY:

To minimize water consumption one should aim to use the water which has been collected, used, purified and reused.

Green Buildings are designed to reduce the overall impact on human health and the natural environment by the following ways:

1)Using energy, water and other resources efficiently.

2)By reducing waste, pollution, and environmental degradation.

SOME IMAGES OF GREEN BUILDINGS

• It is the concept of sustainable building and has largest impact on cost and performance.
• It aims to minimize the enviornmment impact associated with all life-cycles.

WATER EFFICIENCY

FUNDAMENTAL PRINCIPLES

WASTE AND REDUCTION

MATERIAL EFFICIENCY

ENERGY EFFICIENCY:

It is probable to reuse resources.

What may be waste to us may have another benefit to something else.

• The layout of the construction can be strategised so that natural light pours for additional warmth.
• Shading the roof with trees offers an eco-friendly alternative to air conditioning.
