1. Identify unique opportunities
of location
2. Organize Program
(Occupancy Use and Time)
3. Analyze Actual Loads
(Right-size everything)
4. High Performance
Architecture
(Envelope, Sunshading,
Daylighting)
5. Decouple Thermal &
Ventilation
(Utilize the most efficient
systems and equipment
available / heat recovery)
6. Select Renewable Sources
of Energy

concepts: mechanical/architectural
• Automatically controlled passive night cooling
• Upgraded exterior insulation allows precooling of
thermal mass walls
• Ceiling fans extend comfort temperature range
• Custom operable skylights use prevailing
breezes to induce internal airflow
• High efficiency/ low cost rooftop package units
used only as needed (rarely)
• High performance glazing – no need for external
shades

concepts: financial
• Performance based lease provides carrot (and stick) for good
occupant behaviour
• Added construction cost = $44/sf including 32,000 sf PV array
• Drastically reduced reserve requirements for maintenance and HVAC
• Reduced operating expenses – utilities, landscape, etc
• Demisability to reduce churn costs
• Unanticipated cost reductions (e.g. no mechanical screen)
• IF actual energy use meets predicted, than the financial model is
more profitable than standard practice (build to code)
• Future projects – higher rents and lease rates
