- Green building vital in global carbon pictureGreen building growing rapidly in all sectorsGreen building business case is provenBUT, many green buildings are not performing as predictedBuilding energy & water performance reports vitally neededBuildings must measure total carbon performanceZero-net-energy buildings feasible today
- Financial/economic returnRisk mitigationMarketing/public relationsProductivity/health gainsRecruitment/retentionEnvironmental benefitsSustainability concerns
- More than 2 billion sq.ft. certified projects, more than 7 billion sq.ft. registered (maybe as much as 9 million sqft), as of September 1st.
- Issue: Average savings is 35% vs. standard (Kats)BUT, about 25% actually underperformOne LEED Platinum building:Modeled at 61% savingsPerforms at 48% savingsUnderperforming buildings hurt validity of green building premise
- Every building should be beautifulEvery building LEED PlatinumEvery building should aim at “BSAGs”Achieve measured 35 to 45 kBtu/sq.ft. (EUI) performanceDon’t settle for less!BE WILLING to SAY: If it doesn’t perform, it’s not a green building!
- Where SHOULD WE be aiming? I decided to find out!LEED Platinum (or equivalent)Built since 2003>50,000 sq.ft. (>5,000 sqm)Non-residential useMust provide energy data for one yearWater data, as available
- European stretch goal: 100 kWh/sqm/a PRIMARY energy useEuropean site use median: 135 kWh/sq.m.; 43,000 EUIU.S. Average: 400 kWh/m2/a (2003)50% better than average still not good enough!75% (or more) required2030 Challenge (next slide)Solon: 34,000 Btu/sq.ft./year energy use
- Zero Net Energy Buildings are Feasible today; here’s an example:35,000 Btu/sq.ft./year (measured 2011)
- “What gets measured, gets managed”Without reports, we are flying blind/can’t fixWhy should governments put their faith in green building without performance reports?
- “What gets measured, gets managed”Without reports, we are flying blind/can’t fixWhy should governments put their faith in green building without performance reports?

- Traditional Automation does not scale, it’s a hardware model and is too complex, too expensive, too unreliable, too many versions of firmware to supportSwitch were interested in how to tackle the really massive sustainable cities developments in Asia, - developments with in excess of 250k residents – we knew our solution could not deliver for that and none of our competitors could deliver for that scale of projectSwitch made a decision that only the cloud could scale for those kinds of numbersOur experience taught us we had to deliver a solution that could scale with a strong emphasis on energy and environmental since the need to conserve energy will be one of the key drivers for buildings to implement automation

- If you want to score, run to where the ball is headed, not to where it is.Ask yourself and your clients: how green will the built environment be in 2015 to 2020?Non-performing green buildings will pay a penalty in that market!2010 FIFA World CupIf you want to score, run to where the ball is headed, not to where it is.Ask yourself and your clients: how green will the built environment be in 2015 to 2020?What will be the competing buildings over the next 5-10 years?Non-performing green buildings will pay a penalty in that market!
- Green buildings are vital for controlling CO2 emissionsMany buildings do not perform as predicted or as neededWithout reporting actual performance, the entire exercise will be wastedEnergy use best practices metrics are well known; make them your design standards
