  1. RenewAire is On the Move! New 35,000 SF facility

  2. LEED and USGBC Background Eric Truelove The Renschler Company Madison, Wisconsin

  3. US Green Building Council • Formed in 1993 • Nonprofit Consensus-based organization • Develop and administer the LEED Green Building Rating System • Reduce environmental impact of buildings • Use 36% of our total energy output • Use 65% of our electric energy output • Generate 25% of our solid waste stream • People spend 90% of their time indoors

  4. Why LEED Was Created? • Facilitate positive results for the environment, occupant health and financial return • Define “Green” by providing a standard of measure • Use as a design guideline • Recognize leaders • Stimulate green competition • Establish market value with recognizable national “brand” • Raise consumer awareness • Transform the marketplace!

  5. LEED NC- New Construction or Major Renovation

  6. LEED – NC Version 2.1 • Sustainable sites = 14 points • Water efficiency = 5 points • Energy and atmosphere = 17 points • Materials and resources = 13 points • Indoor Environmental Quality = 15 points • Innovation & Design Process = 5 points • 69 Potential points

  7. LEED-NC Certification • Certified Level 26-32 points • Silver Level 33-38 points • Gold Level 39-51 points • Platinum Level 52+ points (69 possible)

  8. LEED - NC Certification Process A three step process: • Step 1: Project registration • Site selection and document registration with USGBC • Step 2: Construction phase • Development of design criteria • Creation of LEED letter templates and required engineering documentation • Step 3: Building Certification • Building completion and submission to the USGBC for final review

  9. RenewAire Renovation • Registered with USGBC on December 20, 2004 • One of four LEED-candidate facilities in Madison • Only major LEED-candidate renovation in Madison • Only manufacturer in the Madison area to be in a LEED registered building

  10. Sustainable Sites • Built on previously developed site • Site is not in 100-year flood plain • Site is not near wetlands • Site is not considered good farm land • Easy access to public transportation • Encourages biking to work

  11. Energy and Atmosphere • High-efficiency cooling (30% beyond code) • High-efficiency heating (10% beyond code) • Six ERVs • Low lighting power densities • No chlorine in new cooling systems • Management may purchase green power

  12. Materials and Resources • Reused over 75% of existing shell • Recycled 75% of construction waste • Used materials with high recycled content • Over 20% manufactured locally • Over 10% mined/harvested locally

  13. Indoor Environmental Quality • Low- or No-VOC or formaldehyde • Adhesives, sealants, paints, and carpets • ERV units recover humidity • Protected HVAC during construction

  14. Status of RenewAire Renovation • Likely to receive 28 points • 26 points needed for LEED certification • 9 additional points possible • 33 points needed for LEED Silver

  15. Conclusions • LEED upgrades cost less than $1/s.f. • Anticipate a payback well under 2 years • Building has been published in March/April 2005, eco structure • RenewAire ERV on 2 other LEED-candidate buildings in Madison • WEEBF • Home Savings

  16. Attributes of Good Ventilation • Ample installed air flow • Pressure balanced – both exhaust and fresh air blowers • Quite operation • Energy efficient • An engineered appliance

  17. Attributes of Good Ventilation

  18. What is RenewAire? An advanced static-plate exchanger

  19. What does RenewAire do? 1. Transfers heat by conduction 2. Transfers humidity using hydroscopicresin

  20. How Does RenewAire Help Achieve LEED Certification?

  26. Manufacturing LEED BuildingRenewAire LLC

  27. RenewAire Production VentilationModelHE2X – 1,500 CFM Exhaust and Fresh Air Supply

  28. Environmental Benefits of an HE2X900 In One Year • Saves 2,500 therms of natural gas • Saves approximately $2,500 • Reduces CO2emissions by29,355 pounds • Equivalent to CO2 reductions from 44 trees • Equivalent to taking 3 cars off the highway • Reduced SO2, NOx, mercury etc.

  29. 2004 RenewAire Sales 3.1 million CFM Saving $4.3 million in fuel Providing efficient ventilation for over 200,000 people!

  30. 2004 RenewAire Sales Result in a Reduction of 25,000 tons of CO2/Yr. !! 5,000 Cars Gone Or 75,000 More Trees
