Editor's Notes
- Show me a SINGLE US building with a carbon calculation & including embodied energy! We are not doing our job without that information.
- Importance of embodied energy; forms a barrier to further carbon reductions
- Importance of embodied energy; forms a barrier to further carbon reductions
- 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) required
- 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
- Here is a chart of actual performance of 15/19 buildings (no labs/hospitals)Median use = 138 kWh/sq.m. (EUI = 44,000)
- Here is a chart of actual performance of 15 buildings (no labs/hospitals)Median use = 135 kWh/sq.m. (EUI = 43,000)
- 75,000 sq.ft.98 kwh/sq.m.Waste heat recyclingNatural ventilation using atrium exhaustHeat recovery from computer serversWater-only (no chiller) cooling via trickle vents and heat exchangers
- 74 kWh/sqm/yearLake water heating/coolingDouble skin façadeNatural ventilation500 employees, 210,000 sq.ft.
- 92,000 sq.ft., 200677 kWp solar PV, 538 sq.ft. vacuum tube solar thermalPrimary/source energy demand: 103 kWh/sqm (with 23 kWh/sqm solar) with embodied energyAtrium buffer zoneActive louvers for shading
- Dutch Energy Rating: A+++GreenCalc score: 1,005185,000 sq.ft.100% sustainable energy on siteEnergy positive buildingBio-diesel 300kW CHP plantOffice: 114 kWh/sq.m./year
- Here is a chart of actual performance of 15 buildings (no labs/hospitals)Median use = 151 kWh/sq.m. (EUI = 44,000)
- 50,000 sq.ft. renovationOn the equatorFocus on daylighting without heat gain41 kWh/sq.m. building energy use45 kWh/sq.m. Solar production
- 816,000 sq.ft.59 kWh/sq.m.Corporate HQStack effect ventilationDaylighting integrationExterior louversVedic architecture
- 77,000 sq.ft.98 kWh/sq.m.6-Star Green Star Office Design5-star NABERSAlmost $3/sq.ft. annual energy cost savingsAutomatic louvers on west façadeActive chilled beamsComprehensive staff/facilities training
- National Cheng Kung University52,000 sq.ft.40 kWh/sq.m./year energy useForest land permanently set aside for meeting zero carbon goal
- Every building should be beautifulEvery building LEED PlatinumEvery building should aim at “BSAGs” – Big Scary Audacious GoalsEvery building should achieve measured 25 to 35 kBtu/sq.ft. (EUI) performanceDon’t settle for less!Retro-Cx or continual Cx to maintain performance levelsBE WILLING to SAY: If it doesn’t perform, it’s not a green building!
- 2030 Challenge:DOE Annual Energy Outlook; Business As UsualAEO (expanded codes)AEO (best available technology)Target is 80,000 BTU; about 32,000 BTU/sq.ft. site energy useBUT this is an average of ALL buildings; new/renovated buildings need to do MUCH better.
- 420,000 sq.ft. building89 kWh/sq.m. electricity use100 kWh/sq.m. total carbonBest tall building in Europe 2011
- ARE YOU WILLING to SAY: If it doesn’t perform, it’s not a green building?
