Phoenix Asu Stardust Ctr Green Bldg Presentation

  1. 1. HUD Workshop: Energy Efficiency, Renewables, and Green Building in Housing Programs September 17, 2008 Building Greener: Materials and Methods Daniel J. Glenn Design Director ASU Stardust Center
  2. 2. The Mission Through research, educational outreach, advocacy and design innovation, the ASU Stardust Center for Affordable Homes and the Family supports organizations, neighborhoods, and professionals in their efforts to improve the growth of quality affordable homes and sustainable communities.
  3. 3. There are over 76 million residential and 5 million commercial buildings in the U.S. Collectively, these buildings consume: 65% of electricity and 37% of primary energy 25% of all water supplies and 30% of all wood & materials Collectively, these buildings generate: 35% of solid waste 36% of CO2 and 46% of SO2 emissions 19% of NOx and 10% of fine particulate emissions (LEEDs US Green Building Council)

  11. 11. Advantages Ease of Use: •Lightweight – 1/5 weight of concrete •Easily shaped – sawed, drilled and shaped like wood w/ standard tools Of •Mortarless – Blocks are laid up with thin-set, not mortar. Navajo Durability: •No organic material FlexCrete •Not susceptible to termites or other pests •Non-allergenic •Highly resistant to mod and fungi Fire Resistant: •Meets ASTM E119 for four-hour rating Energy Efficient: 8” wall has an equivalent R-Value of 25 with no additional insulation Massive wall creates thermal lag for passive heating and cooling Reduces energy use by 40 to 50 percent over stick-frame construction Recycled Content: •Navajo FlexCrete is 60 percent flyash – recycled waste product from coal-burning electrical plants Locally Produced •Navajo FlexCrete is produced in Page Arizona on the Navajo Reservation by the Navajo Nation.

  29. 29. Insulated Concrete Forms Insulated Concrete Forms, or ICFs, are used as a means of energy efficient construction. A typical ICF consists of highly insulative foam combined with a reinforced concrete wall. Through the combined effects of continuous R-Value, reduced air infiltration and thermal mass qualities moderating indoor temperatures, ICFs provide a superior form of wall assembly. According to the Insulated Concrete Form Association, “homes built with ICF exterior walls typically require 44% less energy to heat and 32% less energy to cool than comparable frame homes. Benefits of building with ICFs include:
  30. 30. Insulated Concrete Forms •Outstanding structural integrity, withstanding hurricane force winds and earthquakes. •Energy efficient, with significant savings on heating and cooling. •Increased comfort with more even indoor temperatures and no drafts. •Lower insurance rates. •Quieter than conventionally-built wood frame houses. •Flexibility in the design of a home. Unique characteristics like curved walls are less expensive to build into an ICF home. •Lower labor costs than frame construction. Keep in mind the price of these high-quality materials are slightly more than stick frames. •The metal, concrete and insulating foam can all be recycled.
