Overview

What is a sustainable or green building?

What is LEED?

Why build green? How much does it cost?

Case Study: UBC Life Sciences Centre

Challenges Keys to Success


3/26

What is a sustainable building?

Uses key resources more efficiently

energy, water, materials and land

Reduces ecological loadinggreenhouse

gases, ozone-depleting substances, wastes

Creates healthier environments for people to

live, work and learn

Has lower overall lifecycle costs


4/26

What is LEED?

Leadership in Energy & Environmental Design

Rating system for developing high

performance, sustainable buildings

Voluntary, consensus-based, well recognized

Developed by US Green Building Council

Adapted by the Canada Green Bldg Council

Applications for LEED


8/26

Why use LEED?

Provides a common and consistent framework

for defining a green building

Is relatively simple to implement

Is not overly prescriptive

Can be adapted for local climates and standards

Provides legitimacy of 3rd

party certification Is gaining momentum as the accepted rating

system

Green Building Benefits

25-60% energy savings

30-50% water savings

CBIP financial incentive Improved worker productivitydue to

improved lighting and thermal comfort

Reduced sick time from allergies, asthma &respiratory illness

Lower life-cycle costs

23/26

Challenges

High expectations of building performance

Acoustics

Waterless urinals & dual-flush toilets Motion sensor activated lighting

Operating systems at optimal level


24/26

Keys to Success

Incorporate green principles at the beginning of the

design process

Involve operations staff early in the design process

Avoid unmanageable complexity in building systems

Undertake a thorough commissioning process

Ensure staff are properly trained in building system

operation
