Green Building and Energy Efficiency

  2. 2. ©2017YudelsonAssociates US Energy Consumption by Sector, 2012, DOE/EIA
  3. 3. ©2017YudelsonAssociates US Electricity Consumption by Sector, 2012, DOE/EIA
  4. 4. ©2017YudelsonAssociates Why Start with End Use Demand? •  It’s much more cost- effec/ve to cut demand than increase supply! •  People want “energy services” not “energy” –  Hea/ng/cooling –  Ligh/ng –  Transporta/on –  Etc.
  5. 5. ©2017YudelsonAssociates We Once Thought Green Building Offered A Pathway to a Better Future
  6. 6. ©2017YudelsonAssociates Categories of Concern (LEED 2009): •  Land Use/Transporta/on (26%) •  Water Use (10%) •  Energy Use Reduc/on (35%) •  Materials & Resource Conserva/on (14%) •  Indoor Environmental Quality (15%) Results: LEED Cer/fied ~35,000 projects through 2016, ~20% outside the US (Canada, China, Brazil)
  7. 7. ©2017YudelsonAssociates •  Resource savings (energy, water, waste) – Average energy savings 15% - 25% vs. conven/onal •  Not well documented, however •  Improved building designs, materials & integrated design processes •  Healthier buildings (IAQ, dayligh/ng, views) •  Higher rents & sales price (commercial real estate) •  Produc/vity gains
  8. 8. ©2017YudelsonAssociates Source: US DOE/EIA; Architecture 2030
  9. 9. ©2017YudelsonAssociates •  Defini/on of a “good” building – changed •  Architectural educa/on & prac/ce - changed •  Building engineering prac/ce changed, esp. to reduce energy use – E.g., 60 kBtu/sq.e./year was the norm for offices – Now 30 kBtu/sq.e./year is achieved in common prac/ce – Net zero energy is achievable now in many projects •  Construc/on prac/ces – changed •  Policy makers & gov’t agencies - educated

  18. 18. ©2017YudelsonAssociates •  Exis/ng cer/fica/on systems, such as LEED, won’t get us where we need to go, EVER •  Building codes (e.g., CALGreen in CA) offer some benefits in “raising the floor” for all, but change in overall carbon footprint is limited •  Green building has failed to deliver enough business benefits at current costs to gain widespread adop/on

  25. 25. ©2017YudelsonAssociates •  Worthwhile goal for every new project – Hard on buildings above 4 stories •  Combine low energy use w/renewables –  Onsite solar •  Look for zero net energy retrofit opportuni/es Singapore BCA Academy Net Zero Retrofit, 2009
  26. 26. ©2017YudelsonAssociates •  Cincinna/ Police HQ •  40,000 sq.e., 2015 occupancy •  EUI: 27 kBtu/sq.e./year (first year) – 67% below conven/onal •  PV: 327 kW rooeop/ parking structure •  40 geothermal wells •  Design/build: no budget increase! Architect: emersionDESIGN LLC
  27. 27. ©2017YudelsonAssociates Rooftop Solar PV PV on Parking Canopy
  28. 28. ©2017YudelsonAssociates •  Radically cut carbon emissions – primary goal – 2030 goals: zero net energy on ALL new buildings •  Reinvent green ra/ngs as management tools for con/nuous improvement •  Set Big Hairy Audacious Goals (BHAGs): Increase uptake 10x in 10 years, from 4% to 40% of building area •  How can we do this fast and cheap?
  29. 29. ©2017YudelsonAssociates •  Technology megatrends push every tool and system to be smaller, faster, lighter, cheaper, denser, with more user engagement, etc. •  Green building can piggyback on these megatrends •  What we need are tech-enabled “smart” green buildings, with equally “smart” ra/ng and assessment systems
  30. 30. ©2017YudelsonAssociates
  31. 31. ©2017YudelsonAssociates •  Cloud compu/ng, Big Data analy/cs, Internet of Things, cheap sensors & algorithms •  Real estate opera/onal data is a key asset •  Most facility management will be outsourced – Centralize intelligence, but decentralize sensing •  Opportuni/es huge: Microsoe saves $8M/ year on energy at Redmond, WA campus

  37. 37. ©2017YudelsonAssociates •  Use Big Data analy/cs to streamline evalua/ons •  Leverage algorithms to assess sustainability – Self-driving cars •  Cloud compu/ng offers the chance to start cheaply, across mul/ple devices & proper/es •  It’s important to have a low-cost approach that makes sense to building owners and developers, as well as government
  38. 38. ©2017YudelsonAssociates The Edge, Amsterdam, 98%+ BREEAM rating, 27,000 sensors
  39. 39. ©2017YudelsonAssociates •  Can you hack cer/fying new sustainable buildings at 1/10th to 1/100th the current cost and 50x faster? –  Hint: You may have to audit results at random, like the IRS –  Using only input from design & construc/on documents? •  Can you come up with a credible program for massively improving exis/ng buildings’ energy use? –  Meet goal of 50% less energy use by 2030 –  Use drones to document energy waste via thermography? –  Use virtual/augmented reality to drive change?
  40. 40. ©2017YudelsonAssociates •  Most efficient Net-Zero energy approaches vs. climate zone and building type •  Benefits of district-scale energy vs. rooeop solar; integra/on of rooeop solar with onsite storage vs. “grid storage” •  Green chemistry for healthier building materials that are as cheap & effec/ve as currently used •  “80/20” rules for healthy buildings (e.g., what specific differences make the biggest overall difference?)
