From Vision to Strategic Planning
• Create a vision
• Develop a strategic plan
– Achievable targets
– Timelines
– Implementation – Commissioning
– Measurement and Verification
• Create programs
• Attain partnerships/alliances
– Funding agencies
– Utilities and government

Integrated Design Process
• Series of workshops and design meetings
– Industry experts and utilities
– Government agencies
• Target energy efficiency of the homes/buildings
– Building envelope – Highly efficient appliances and technologies
• Mechanical
• Lighting
• Alternate forms of energy
– Renewable technologies
– Community energy systems

Natural Ventilation
• Operable windows
• Vertical and horizontal
ventilation
• No cooling requirement
• Thermal mass
• Performance exceeds
energy model!!

Determining Demand – Energy Use and Load Profiles
Baseline Model - Code
• Ontario Building Codeconstruction, HVAC systems
and lighting
• Typical process loads andoccupancy
Design Model - LEED
• “Best practice” construction,HVAC systems and lighting
• Same process loads and
occupancy as Baseline
• 10-25% improvement overbaseline
Load Model
• Same as Design
• Calculate hourly demands bysetting heating and cooling
plant efficiencies to 100%
• Assume identical pumpingenergy to Design model
