Worcester Art Museum:Green Technology Evaluation Travis Collins ECE Christopher Gowell ME Aaron Hall-Stinson ME Advisors: Professor William Baller Professor Stephen Bitar
Global Impact • Loss of Natural Resources • Reliance on Oil • Commercial Office Buildings Consume 18% of National Energy
Higgins Education Wing • Built in 1970 • Office space, studios, classrooms, and storage • Facilities Master Plan includes options to construct a third floor over the existing wing
Objectives • Perform an energy audit and estimate future office energy usage • Determine which green technologies will be most beneficial to the museum • Examine funding sources • Provide detailed recommendations
Energy Audit • Gathered energy bills for past 3 years • Office by office walkthrough • Evaluated electrical usage of each device with Fluke Meter • Evaluate Usage based on device operating hours and operational modes
Power Evaluation • Found heating and cooling to be biggest consumer • Followed by lighting • Due to large amounts of incandescent bulbs • Found museum employees to be conscious of energy • Lighting system reevaluation needed due to specific artistic needs
WAM Energy Usage (FY09) 380,000 kWh used annually in the Higgins Wing kWh
Green GoingGreen Possible Options • Photovoltaic Array (Electric Solar Panels) • Green Roof (Vegetative Roof) • Wind Turbine
Ruled Out • Wind • Required Footprint • Zoning • Green Roof • The Good • Triple Life of Existing Roof • Increase Drainage Efficiency • The Bad • Substantial Roof Weight Requirements • Very Long Payback Period • Minor Thermal Insulation Gains • Limited Funding Solutions Comparatively
Photovoltaic Overview Selection Criteria • Direct Energy Production • Funding Solutions • Best Payback Period • Best Applicable Advantages
Worcester State • 540 195 watt panels on ballasted docking station • Produces 140,000kWh annually • 33,000 sq. ft of roof space • Evergreen ES-195 series panels • Cost $825,000 • Funded $570,00 by MTC • $255,000 from CREB (clean renewable energy bonds)
Mass MoCA Solar • 51.6 kW electric PV array • ~48,000 kWh generated annually • Evergreen Solar (Massachusetts based) and SCHOTT Solar panels
Mass MoCA Funding • Project Cost: $ 709,500 • Solar Array: $ 391,560 • Educational Exhibits: $ 128,500 • Other Upgrades: $ 189,440
Museum Projection Option 1 • Installation of a ballasted photovoltaic system • 340 Panels Installed • 57kW Power Output • $427,000 Initial Install • 71,000kWh Produced Annually • Power 8 2-story homes or take 14 cars off the road annually • Save 44 tons of CO2 • $11,000 Annual Savings • (2 Free Months)
Future Possibilities Option 2 • 520 Total Panels Installed • 87kW Total Output • Total Cost $ 650,000 (additional $ 223,000) • 109,000kWh Produced Annually • Power 11 homes or take 23 cars off the road • Save 70 tons of CO2 • $16,000 Annual Savings
Projected Gains • Current Structure • 20% Electrical energy supplied • After Addition • 25% Electrical energy supplied of projected usage
Economic Impact • Locally manufactured components • Evergreen Solar and SolectriaRenewables • Local jobs
Recommendations • Apply to MTC for Green Building Initiatives Program • Install outlined PV array on Higgins roof • With extra MTC grant money execute a lighting survey and update as recommended
