1 BUILDING COMMISSIONING & MONITORING

• Building energy models are just projections of

how efficient a building could be under a given set

of circumstances and assumptions. It omits add-

ins, installation errors, and human behaviour, etc...

1 BUILDING COMMISSIONING AND MONITORING:

Buildings Do Not Perform as Modelled

Stephen Carpenter - Enermodal Engineering

1 BUILDING COMMISSIONING AND MONITORING:

Measured Energy Performance of LEED Buildings

1 BUILDING COMMISSIONING AND MONITORING:

Models Don’t Work

1 BUILDING COMMISSIONING AND MONITORING:

Calibrating the Model

- Enermodal Engineering

1 BUILDING COMMISSIONING AND MONITORING:

Identifying Performance Issues

• Data Collection

• Upfront Investment

• Monitoring Behaviour

• Resolving Issues

1 BUILDING COMMISSIONING AND MONITORING: Challenges

2 INTEGRATED DESIGN PROCESS

2 INTEGRATED DESIGN PROCESS: What is it?

• IDP brings together all of the building

stakeholders early in the design process to align on

objectives and provide expertise.

3 WATER

3 WATER

• Water is the next carbon.

3 WATER: Headlines

• An E.P.A. study last year estimated that $335 billion

US would be needed simply to maintain the nation’s

tap water systems in coming decades. – NY Times

• In 2007, the government of Alberta approved the

withdrawal of 119.5 billion gallons of water for tar

sands extraction. – The Dominion

• Canada ranks a dismal 28th among the 29 nations

of the OECD in terms of per capita water

consumption. Only Americans use more water than

Canadians. - www.environmentalindicators.com

3 WATER: Challenges

• Individual Metering

• Water Pricing

• Water Rights

4 RESILIENT CITIES

4 RESILIENT CITIES

• Regardless of our ability to improve energy

efficiency and reduce carbon emissions, some big

changes are coming. Can our cities adapt?

4 RESILIENT CITIES: Threats

• Climate Change

• Drought

• Heatwaves

• Storms

• Population Growth

• Security

• Public Services

• Economic Opportunity

• Peak Oil

• Transportation

• Energy Prices

4 RESILIENT CITIES: Principles

• Carbon Dependency Reduction

• System Diversity

• System Redundancy

• Durability

• Flexibility

• Feed-Back Sensitivity

• Responsive to Natural Systems

• Local self-sufficiency

5 SMART GRID/SMART APPLIANCES

5 SMART GRID/SMART APPLIANCES

• Smart Grids allow for optimal use of energy

generated. Right now only 10% of energy extracted

makes it to the end user, so efficiency does not

address 90% of the energy loss.

5 SMART GRID/SMART APPLIANCES: Address Issues:

• Load Shifting

• Renewables

• Peak Shaving

• Power Vampires

5 SMART GRID/SMART APPLIANCES

- Zerofootprint

- GE

5 SMART GRID/SMART APPLIANCES

• Compatible Platforms

• Proprietary Data

• Privacy

• Infrastructure
