Energy Modeling 2009 Presentation

  1. 1. “ LEEDership for Sustainability” “ GREEN BUILDING” -Not the conversation of a decade ago <ul><ul><li>Accreditations: CHEERS, HERS Rater, Sustainable Building Advisor, CGBP, LEED AP </li></ul></ul><ul><ul><li>Members: USGBC Northern California Chapter, Emerging Green Builder, Architecture 2030, BOMA, RESNET </li></ul></ul>-Matt Macko
  2. 2. Energy Modeling <ul><ul><li>Lee Eng Lock – “Almost anything that uses energy needs to be looked at with a new pair of eyes” </li></ul></ul>
  3. 3. People Don’t Want Energy <ul><li>Hot Showers Cold Beers </li></ul>They Want:
  4. 5. AB 1103 <ul><li>Assembly Bill </li></ul><ul><ul><li>Requires electric and gas utilities to maintain records of building energy consumption </li></ul></ul><ul><ul><li>Moving the industry toward better building efficiency </li></ul></ul><ul><ul><li>California Wide – Existing Stock </li></ul></ul><ul><li>Portfolio Manager </li></ul><ul><ul><li>ENERGY STAR Score </li></ul></ul><ul><ul><li>Same as LEED EBOM </li></ul></ul><ul><li>2010 you will see the effect </li></ul>
  5. 6. Who? <ul><li>Who is modeling for? </li></ul><ul><li>Its for EVERYONE on EVERY project whether LEED or not </li></ul><ul><li>Numerous studies have shown there are no day lighting or energy benefits with window-to-wall ratios over 60 percent </li></ul><ul><li>25 and 40 percent is optimum </li></ul><ul><li>Yet we continue to build glass boxes </li></ul>
  6. 7. When? - Early <ul><li>When just 1% of a project’s up front costs are spent…up to 70% of its life-cycle cost may already be committed.” </li></ul><ul><ul><li>Joseph Romm, energy expert </li></ul></ul><ul><li>A couple thousand up front can pay for itself in the first couple months </li></ul><ul><li>Small 4 story Soma building – built 2001 </li></ul><ul><ul><li>Monthly spending $20,000 on energy </li></ul></ul>
  7. 8. What? <ul><li>DOE2 </li></ul><ul><ul><li>DOE2 1e-Visual DOE </li></ul></ul><ul><ul><li>eQuest </li></ul></ul><ul><ul><li>EnergyPro </li></ul></ul><ul><ul><li>HAP-Carrier </li></ul></ul><ul><ul><li>Trace </li></ul></ul><ul><ul><li>Energy 10 </li></ul></ul><ul><ul><ul><li>Weather maker </li></ul></ul></ul><ul><ul><ul><li>Energy Plus </li></ul></ul></ul><ul><ul><ul><li>TRYNSYS </li></ul></ul></ul><ul><ul><ul><li>Green Building Studio </li></ul></ul></ul><ul><ul><li>Its not just Title 24 calcs </li></ul></ul><ul><ul><ul><li>Studies show the most effective models come from outside 3 rd parties – and rarely from engineering firms </li></ul></ul></ul>
  8. 9. Graphical User Interfaces <ul><li>Makes energy modeling easy to use </li></ul><ul><li>We used to text edit for DOE Simulations </li></ul><ul><li>DOE – working to develop better GUIs </li></ul>
  9. 10. Energy Modeling Benefits in Each Phase?
  10. 12. Load Reduction Renewable Efficiency Water Waste Energy
  11. 13. Energy Modeling Basics Reduced Glazing Area Shading Landscaping Building Orientation Natural Resources Heat Island Reduction Mechanical Energy Efficiency Temperature Humidity Occupancy Plug Loads Lighting

  14. 25. Strategies <ul><li>Energy Efficient Measures </li></ul><ul><ul><li>Often an Existing Building term </li></ul></ul><ul><ul><ul><li>Need to be thought of in the same sentence </li></ul></ul></ul><ul><ul><li>www.eere.energy.gov </li></ul></ul><ul><ul><li>www.fypower.org </li></ul></ul><ul><ul><li>www.dsireusa.org </li></ul></ul><ul><ul><li>www.doe.gov </li></ul></ul><ul><ul><li>www.fishnick.com (Commercial Kitchen) </li></ul></ul><ul><ul><ul><li>3000 - only 800 have received a basic energy audit </li></ul></ul></ul><ul><li>Pacific Energy Center </li></ul><ul><ul><ul><li>Upcoming classes </li></ul></ul></ul>
