RenewAire is On the Move! New 35,000 SF facility
LEED and USGBC Background Eric Truelove The Renschler Company Madison, Wisconsin
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
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!
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
LEED-NC Certification • Certified Level 26-32 points • Silver Level 33-38 points • Gold Level 39-51 points • Platinum Level 52+ points (69 possible)
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
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
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
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
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
Indoor Environmental Quality • Low- or No-VOC or formaldehyde • Adhesives, sealants, paints, and carpets • ERV units recover humidity • Protected HVAC during construction
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
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
Attributes of Good Ventilation • Ample installed air flow • Pressure balanced – both exhaust and fresh air blowers • Quite operation • Energy efficient • An engineered appliance
What is RenewAire? An advanced static-plate exchanger
What does RenewAire do? 1. Transfers heat by conduction 2. Transfers humidity using hydroscopicresin
RenewAire Production VentilationModelHE2X – 1,500 CFM Exhaust and Fresh Air Supply
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.
2004 RenewAire Sales 3.1 million CFM Saving $4.3 million in fuel Providing efficient ventilation for over 200,000 people!
2004 RenewAire Sales Result in a Reduction of 25,000 tons of CO2/Yr. !! 5,000 Cars Gone Or 75,000 More Trees
