This presentation outlines a proposal for the City of Kelowna's Design & Construction Services Department to initiate more sustainable practices. It defines sustainability and a systems approach to consider a building's economic, environmental and social impacts. The goals are to minimize resource use and waste while improving occupant well-being. Initiatives proposed include establishing sustainability baselines, evaluating options based on ease of implementation, costs and benefits, and supporting integrated design processes. Principles outlined are to choose simpler solutions when possible and evaluate consultants on sustainable design qualifications.

1. INTRODUCTION
This presentation outlines an option for the initiation of a new
sustainable practice to be used by the City of Kelowna’s Design &
Construction Services Department
hugh j bitz City of Kelowna - Building Design & Construction Manager Competition

2. DEFINITIONS
SUSTAINABILITY - values environmental integrity as well as economic
prosperity, and community well being (triple bottom line)
PROBLEM - how to make/facilitate informed decisions about sustainable
choices regarding building site, program, design and construction.
ECONOMIC – ENVIRONMENTAL – SOCIAL

3. DEFINITIONS
Systems Approach – consider a building as a system with ‘quantifiable’ inputs
and outputs. The building is part of a larger system defined by economic
environmental and social factors.

4. SUSTAINABLE SYSTEM
Goal- manage (minimize) system inputs and waste while increasing user
comfort, productivity, health & safety. Minimize buildings impact on the
environment while contributing to economic and social well being.

7. SUSTAINABILITY INITIATIVES
Initiatives to making/facilitating informed decisions about sustainable design
 Establish a baseline for sustainability
 Encourage a clear correlation with LEED even if certification is not
pursued. i.e. LEED silver

9. SUSTAINABILITY INITIATIVES
Initiatives to making/facilitating informed decisions about sustainable design
 Establish a baseline for sustainability
 Encourage a clear correlation with LEED even if certification is not
pursued. i.e. LEED silver
 Evaluate choices based on :
 Ease of implementation
 Capital cost relative to conventional
 Payback($, reduced inputs, reduced output)
 Lifecycle/ease of maintenance

10. SUSTAINABILITY INITIATIVES
Example
waterless urinals are easy to implement have no capital cost increase over
conventional urinals, and the payback - in terms of reduced inputs and
outputs - is immediate.
photo voltaics are currently more difficult to implement, require more
rigorous coordination with other systems, are more expensive than
conventional systems and thus require longer payback

11. SUSTAINABILITY INITIATIVES
Principles to making and facilitating informed decisions about sustainable design
 Establish a baseline for sustainability
 Encourage a clear correlation with LEED even if certification is not pursued. i.e.
LEED silver
 Evaluate choices based on :
 Ease of implementation
 Capital cost relative to conventional
 Payback($, reduced inputs, reduced output)
 Lifecycle/ease of maintenance
 Simplicity vs. Complexity

12. SUSTAINABILITY INITIATIVES
Example
Rainwater harvesting for irrigation use is relatively cheap and easy to install
and is a simpler system to maintain (catchment, storage, distribution)
VS
Rainwater harvesting for potable use requires a more complex system
(catchment, storage, treatment, distribution) cost more per unit of water and
is more difficult to maintain

13. SUSTAINABILITY INITIATIVES
Principles to making and facilitating informed decisions about sustainable design
 Establish a baseline for sustainability
 Encourage a clear correlation with LEED even if certification is not pursued. i.e.
LEED silver
 Evaluate choices based on :
 Ease of implementation
 Capital cost relative to conventional
 Payback($, reduced inputs, reduced output)
 Lifecycle/ease of maintenance
 Simplicity vs. Complexity
 Evaluate consultants on sustainable criteria :
 RFQ /RFP- request that consultant team outline their approach regarding
sustainable design. Weight this approach in evaluation of qualifications/proposals
 Support an integrated design process
