Arch 2030 Presentation

  1. 1. Architecture 2030 Meeting the Challenge
  2. 2. The 2030 Challenge All new buildings, developments and major renovations  shall be designed to meet a fossil fuel, GHG‐emitting,  energy consumption performance standard of 50% of the  regional (or country) average for that building type. 60% in 2010 70% in 2015 80% in 2020 90% in 2025 Carbon‐neutral in 2030 (using no fossil fuel GHG emitting  energy to operate).
  3. 3. The 2030 Challenge These targets may be accomplished by implementing  innovative sustainable design strategies, generating on‐ site renewable power and/or purchasing (20% maximum)  renewable energy and/or certified renewable energy  credits.
  4. 4. The 2030 Challenge “You’ve got to eat your energy  efficiency vegetables before  you can have your renewable  energy dessert.” – Jeff Lyng,  Colorado Governor’s Energy  Office Photo provided by NREL
  5. 5. The 2030 Challenge Source: Energy Information Administration, 1995 Commercial Buildings Energy Consumption Survey
  6. 6. The 2030 Challenge Innovative Design Strategies Hierarchy Controls Mechanical Daylighting Envelope
  7. 7. Envelope Remember, code is the minimum allowed.   It won’t get you to your goal. Instead, start with ASHRAE’s Advanced  Energy Design Guides Use energy modeling early to determine  performance goals. Climate zones change requirements.   Breckenridge is different than Denver. Optimize window selections for  orientations. Look at new technologies.  SIPs, ICFs, etc.
  8. 8. At least they can’t say they don’t have any windows. Daylighting
  9. 9. Daylighting Building needs to be oriented properly. Need to aggressively target the use of  artificial lights. Artificial lighting should be tied into  daylighting, and should dim when  conditions allow. Windows need to a balance of thermal  performance, solar performance, and  visible light transmittance. Christa McAuliffe E.S. Direct light must be controlled! Take advantage of the 300 days of  sunshine a year in Colorado. 
  10. 10. Mechanical Efforts in envelope and  daylighting should reduce  mechanical systems sizes. Look at innovative  strategies: geoexchange,  natural ventilation,  evaporative cooling, energy  recovery, chilled beams. 220-ton heating/cooling “plant” Integrate HVAC  with  occupancy sensors.

  12. 12. Controls Can improve efficiency of  system, but won’t make up for  lost efficiency in envelope,  daylighting, or mechanical  systems. Need to be flexible for future  technologies Look at systems that integrate  all systems – lighting,  mechanical, and schedules.
  13. 13. Dilemmas Gas versus electric? Source Power:  Do we design for the now (coal burning plants), or for the  future (renewable energy)? Renewable energy sources – photovoltaic, wind. Supply has gone up, but so has demand (and cost). Limited control of the building performance after turnover. Energy  Star measures actual use.  Increase the education of our building users. Include ongoing commissioning.

  18. 18. Christa McAuliffe Elementary  Final Thoughts It reached the current (2008) goals of Architecture 2030. Need to monitor ongoing performance and compare to model. Projects started in the next two years will need to be even more  efficient to meet the 2010 requirements. Eventually, we’ll need to include on‐site renewable energy (or  purchase credits) to achieve the requirements.
