“…North America’s most complex energy-efficient buildings is also sited in one of its most challenging climates.” GreenSource Magazine, March + April 2010 a new McGraw Hill publication edited by Architectural Record
100 % fresh air, 24/7 year round Reduction of 1.25 sick days / employee / per year = 1$ million+ in cost savings annually 
 50% reduction in thermal comfort complaints
89 kwh/m2/yr Over $7 million in energy savings savings in the past 10 years 2300 occupants An increase in staff commuting by transit, up from

Natural ventilation potential. From 25% to 80% of occupied hours Mechanical Ventilation. 
 Too cold outside

Mechanic al Ventilatio n. too warm & humid
Economic Considerations NEGATIVES - Higher embodied energy in double façade than single façade - Higher capital costs - Additional square footage - Engineering expertise / performance analysis is required POSITIVES - Downsized mechanical systems - Lower operating costs - Better control and access to daylight - Higher level of user control - Higher degree of comfort for occupants - Natural ventilation in buildings that typically wouldn’t

It is all about Process and the Team Passive first, then active. Define the supply and demand side reduction Architecture AND engineering, at every stage of the project Turn climate challenges into opportunities Simulation tools for decision-making and testing, - at all stages. Incremental-ness: let the solutions evolve step by step, iteratively. Empower occupants to control their personal space (shade, light, air) Invest in metering and verification. Invest in post-occupancy comissioning Every building is a legacy. Do the ‘right’ thing for the environment & the community Ignore LEED® (for a while) Architecture is dynamic: design it to breathe, think, and respond Think first about improved quality of space, not cost and savings The highest quality of space can also be the most energy efficient To innovate, Rethink rather than Reinvent
