QUESTIONS

Why we need to do building environmental

assessment?

How to do it?

Who responsible for this work? What is the significant of development of building

environmental assessment?



FACULTY OF ENGINEERINGSustainability and Environmental Assessment

Concept Definition- (Khamidi, 1997)-

3. SUSTAINABILITY CONCEPT 2 (Built Environment Scholar)

“Sustainable design recognizes;

The interdependence of the built and natural environments; it seeks to

harness natural energy flows and biological processes, eliminate relianceon fossil fuels and toxic materials, and improve resources and efficiency.

In the short run, the impact of these changes will reduce the

environmental impact of our designs. In the long run, the goal is to create

buildings that are not only not harmful but actually part of natural systemsand restorative of those systems.

Sustainable design is concerned with the quality of our environment as a

whole system”.




OUR RESPONSE: COP15 2009 has seen that Malaysia pledged toreduce up to 40% in terms of emissions intensity of GDP by the year

2020 compared to 2005 levels (Prime Minister Malaysia, 2009).

Background:

…“Malaysia today isfacing two of the world’s

most pressing issues,namely climate changeand energy security”… (Prime Minister Malaysia,2009;2010). disseminate

Issues - (Razak, 2009; KETTHA, 2009)

3. SUSTAINABILITY CONCEPT 3 (Government Policy)



Why we need building environmental

assessment?



BUILDING ENVIRONMENTAL ASSESSMENT

Why it is important?

Buildings are the single largest consumer of energy

produced by fossil fuel power plants, therefore the

biggest contributor to the carbon emissions

For example, in U.S., buildings account for 74% ofelectrical consumption, 39% of total energy use, 40%

raw material use, and 30% waste output

Inefficient building trigger variable operating

expenses (e.g., energy use, maintenance issues, and

cost to change (e.g., material, additional facilities,and etc)



PROBLEMS RELATED TO BUILDING

Solutions



Social aspects of welfare, health, safety and comfort

Functional and economic aspects of use incorporating

flexibility

Technical aspects of serviceability, durability and

reliability

Ecological aspects of biodiversity and resource depletion

plus air, water, and soil pollution

Sustainability design of building

must address :

Management of sustainability issues requires built environment

professionals to work through increasing complex problems while

instigating new systems/ideas to overcome difficulties in

gathering, analyzing and verifying KNOWLEDGE

3. SUSTAINABILITY CONCEPT 6 (Authority)

Low Carbon Green Building- (SEDA, 2012)



Based on 2 fundamental concepts

1. Life cycle consideration

2. 1st principles of green engineering

12 PRINCIPLES OF GREEN ENGINEERING

• Green engineering focuses on how to achieve sustainability throughscience and technology

• It provides a framework for scientist and engineers to engage in when

designing new materials, products, processes, and systems that are benign

to human health and the environment.

SOME IMPORTANCE ISSUES

To what extend Life Cycle Analysis

(sustainability assessment) could be integral to

building environmental assessment?

How are assessment tools viewed by various

stakeholders in the building industry (profit vs.building env. sustanability)



N ATURAL DISASTER AND BUILDING

S AFER STRUCTURES

Major natural disaster around the world

Earthquakes

Tsunami

Flood

Natural disaster could damage or destroyednumerous buildings, bridges, and other structures.

By monitoring how structures respond to this natural

disaster, and applying the knowledge gained,scientists and engineers are improving the ability ofstructures to survive major earthquakes. Many livesand millions of dollars have already been saved bythis ongoing research.
