Challenges Facing Construction Industry
Environmental impacts by construction industry in Korea
About 100,000 tons of GHG emitted Construction of 5 km
highway
About 47,000 tons of GHG emitted Construction of 100,000
m2 housing complex
About 20% of energy consumption
( 29% - USA, 33% - Japan)
Commercial and
residential buildings sector
Climate Change and Energy Consumption
[Ref.] MLTM (2010), press release
About 23% of energy consumption
( 41% - USA, 26%- Japan) Transportation sector

Commitment to
Environmental Management
Part II.
To minimize environmental impact throughout the life cycle of design-
procurement-construction-operation &
management
Campaigns and policies to cultivate eco-mind and engage into business practices and
daily activities.
Green Engineering Process Construction sites with green practices Green products
Green Design Green Procurement Green Construction Green Management

Implementation of
Green Engineering Process
[Ref.] Miguel Mendez (2007), The role of chemical engineers in green engineering, Chemical Engineering
Important to consider product life
cycle (PLC) in the
process design stage.
80% of the costs are committed by design decisions at early stage of engineering
98% of the operating costs are committed
-
Best Practice - Green Building
(1) Goal:
Construction of a high performance building through integrated planning and simulation at
design stage

Action 3. Target
The cost impact* by category
Q1
Sustainable Site (8.9%)
Water Efficiency (3.7%)
Energy (63.7%)
Materials (2.5%)
Indoor Environmental
Quality (16.3%)
Soft cost (Consulting) (4.9%)
Cost Impact* 70% 0%
Measurable targets with emphasis on energy consumption
* The proportion of
the incremental cost
How to reduce the incremental cost?
Q2
Simulation-based optimization for
performance enhancement
Data-based optimization for cost
minimization
Search and identify alternative
technologies and items
Apply knowledge from accumulated
database (cost vs. performance)
Optimization
Alternative items/technologies
Respond to related regulations
Set measurable targets and apply (cost) effective technologies
