Focus Lowest Capital Cost • Complex building technology • Airtight and lightweight envelope • Prescriptive energy targets • “All-Air” mechanical systems
• Combined temperature control and ventilation • Complex and fast acting controls
Technology • Multiple control network • Sub-optimal information • Lower performance
Result High Energy Use & Operating Cost
• 30% of commercial buildings have illness associated with them • Poor indoor air quality 18% lower productivity • 150 million person-days/year lost to absenteeism due to poor • indoor air quality • Estimated cost: $8.1 billion 21¢/sq. /year
TELUS Garden | North American Trends
• Focus Long-Term Performance • Passive and integrated technology • Massive envelope and operable windows • Energy performance target • “Hydronic” mechanical systems • Temperature control separated from ventilation • Simple slow acting controls • Stable IEQ
Technology Integrated approach Simple solutions Increased occupant control
• Result Low Energy Use & Operating Cost
TELUS Garden | European Trends
• Performance metrics for “productivity” are difficult to define and measure • Building energy cost ~ $2.00/ft2/year • Occupants are paid ~$200/ft2/year • Be careful when saving energy…
• A 25% savings in energy would be negated by a 0.25% drop in productivity! • Productivity costs are
100 times more important
