  1. Installing Renewable DG in High Performance Schools in Connecticut Steven Weisman Peregrine Energy Group, Inc. April 10, 2006

  2. Project Objectives • Analyze current trends in construction and financing • Describe energy issues and opportunities • Identify ways to facilitate HPS and renewable DG • Determine major market barriers • Recommend strategies CCEF can pursue

  3. Methodology: Research • Best practices (Federal and State) • Current school construction in CT • Energy performance of CT schools • CT General Statutes & legislation • CT school reimbursement process (DOE) • CT life cycle cost analysis process (DPW) • CT Energy & Green Building Initiatives

  4. Methodology: Interviews • CT Dept. of Education • CT Dept. of Public Works • New Haven Schools Construction Dept. • Westmount Management, Inc. • Institute for Sustainable Energy at ECSU • Massachusetts Technology Collaborative • Massachusetts School Building Authority

  5. Connecticut Schools Today • Average age almost 50 yrs. (1027 schools) • Over 250 schools without major renovation for 20-plus years • CT spent $3.8 billion for school project reimbursements from 2000 – 2005 • Energy efficiency well below national average, with 60% in lowest quartile • Average energy cost per student more than 50% higher than national average

  6. Energy Use in CT Schools Source: Institute for Sustainable Energy: EPA Benchmarking

  9. High Performance Schools “People & Environmentally Friendly” • Oriented to maximize solar benefits • Integrated into community • Design optimizes thermal, visual, acoustic comfort • Focused on indoor air quality • Energy efficiency exceeds code by 20% or more (Energy Star) and design incorporates renewables • Conserves water, reduces waste water, limits run-off • Less expensive to operate and maintain

  10. High Performance Schools “Focus on Design & Construction Processes” • Recognize long-term impacts of decisions • ‘Life Cycle Cost’ more important that ‘First Cost’ • Take an integrated approach to design • Use building metrics and modeling to specify performance • Engage ‘commissioning agents’ ensure design compliance and provide quality assurance • Require ongoing performance measurement and • Provide for systems optimization

  11. High Performance Schools

  12. HPS in Connecticut:City of New Haven Program • 10 yr. program will result in 50 new or renovated schools • Since 2003, all meet combined LEED and Energy Star standard • Seek a minimum energy score of 75 (of 100) • To date, 8 new schools with anticipated annual savings of $400,000 and 30% of use • Equals 20-yr. savings of $10,000,000

  13. New Haven Keys to Success • Leadership • Long-term perspective • High Performance School Design Guide • Integrated design • Building modeling • Early and ongoing commissioning • Process and performance auditing for continuous improvement

  14. Renewable DG Case Study:Barnard Magnet School • 68kW PV rooftop system in New Haven • Integrated into environmental curriculum • $612,000 materials and labor cost • $361,940 CCEF grant • $238,000 CT DOE reimbursement (95% for magnet) • $12,503 net cost to City • 1.1 yr. payback ($11,616 savings/yr. @$0.13/kWh)

  15. Renewable DG in CT Schools:Extrapolated Economics “Barnard School” in Other CT Cities • 68kW PV system: $612,000 materials & labor • $250,060 cost after $361,940 CCEF grant • Net cost after CT DOE reimbursements: • Bridgeport: $50,012 / 4.3 yr. PB (80.00% DOE grant) • Middletown: $97,348 / 8.3 yr. PB (61.07% grant) • Rocky Hill: $144,685 / 12.5 yr. PB (42.14% grant) • Glastonbury: $167,890 / 14.4 yr. PB (32.86% grant)

  16. Barriers to HP & Renewables in CT Schools • HPS are new and unfamiliar in CT • Persistent ‘first cost’ focus at all levels • Local champions are needed • Specialized technical support required • HPS cost more to design and build

  17. Opportunities for HPS • Proposed legislation and related activity • New Haven projects • Potential collaborators • CCEF initiatives and funding • Utility ‘Energy Conscious Blueprint’ • MA Green Schools Initiative model

  18. Other Related CT Initiatives • CT Climate Action Plan • CT Green Buildings Council Initiative • 2006 State Energy plan of CEAB • Institute for Sustainable Energy • CCEF Renewable DG Program

  19. MA Green Schools Initiative Funds committed for: • School feasibility studies and modeling • Staff position at MA DOE • Design Standards development, based on CHPS • Project design and construction • Project evaluation • Local outreach and workshops

  20. MA Green Schools Initiative Results, based on study of 8 schools: • Green schools cost 3-4% more • Incentives (utility, DOE, MTC) on average cover 75% of incremental cost • Benefits over 20 yrs. exceed costs by factor of 6 to 8

  21. Recommended Strategies for CCEF • Policy Initiatives • Collaborations • Targeting • Education and Training • Technical Support • Financing

  22. CCEF Activities: Policy • High Performance Building legislation • CT DOE incentives for HPS construction • CT DOE support for commissioning • CT DPW requirement for whole building LCCA and modeling • Encourage New Haven-type city efforts

  23. CCEF Activities: Collaboration • Create a HP Implementation Task Force to lead and coordinate actions • Join with CEEF to get utility resources • Establish a HPS Coordinator position • Partner with Institute for Sustainable Energy • Collaborate with NGOs on outreach

  24. CCEF Activities: Targeting • Establish an “early warning system” for project opportunities • Identify districts where HPS and renewables would be attractive • Pursue the over 250 schools with no renovations for 20-plus yrs. • Find cities that can replicate New Haven

  25. CCEF Activities: Technical • Develop “Design Standards” for CT • Fund design charrettes for towns • Fund feasibility studies and modeling • Support creation of Energy Information Service to track and benchmark energy use by schools • Fund a HPS Coordinator position • Fund analysis of results

  26. “Top-down” vs. “Bottom-up” • With or without legislation, transition to HPS and renewables will be a challenge • New thinking is needed • Stakeholders must align and collaborate • Knowledge must be nurtured and shared • Support infrastructure must be built • Resources must be provided

  27. Straw Budget for CCEF HPSP • HPS Design Guide $70,000 • HPS Coordination ( for 3 yrs.) $270,000 • City Planning Grants (4) $100,000 • Outreach (for 3 yrs.) $45,000 • Trainings $20,000 • Design Charrettes (30) $150,000 • Feasibility / Modeling (15) $300,000 • Analysis and Documentation $45,000
