Dispelling Myths and Making Cents of Multifamily Green Building Certification

Green building certification is a great way to add value to a community for both owners and residents; however, it is often not pursued due to misconceptions that the process is too expensive and complicated. Plus, with so many certification programs out there, how do you decide which one to use? Join a panel of industry experts as they dispel some of the common myths about the complexity of certification as well as compare and contrast the costs and benefits of the most popular programs being used- including the National Green Building Standard (NGBS), Energy Star and LEED.

Dispelling Myths and Making Cents of Multifamily Green Building Certification

  1. 1. Dispelling Myths and Making Cents of Multifamily Green Building Certification
  2. 2. Meet Your Speakers Kate Hamblet KEPHART Architects Elizabeth Gillmor Energetic Consulting Engineers Jeff Slaugh US-EcoLogic
  3. 3. Session Description Green building certification is a great way to add value to a community for both owners and residents; however, it is often not pursued due to misconceptions that the process is too expensive and complicated. Plus, with so many certification programs out there, how do you decide which one to use? Join a panel of industry experts as they dispel some of the common myths about the complexity of certification as well as compare and contrast the costs and benefits of the most popular programs being used—including the National Green Building Standard (NGBS), Energy Star and LEED.
  4. 4. Session Learning Outcomes • Understand the value and benefits green certification can add to a multifamily property, the costs involved in obtaining and the design and construction best practices to maximize return on investment. • Learn how to shape the design process and documentation to reduce costs and ensure a smooth transition to construction. • Explore the requirements of each program, and the incentives available to help offset costs including tax credits, expedited permitting and reduced permit fees. • Learn how each certification program addresses building types, and how these differences will help you determine the best program to fit your needs.
  5. 5. Credit(s) earned on completion of this course will be reported to AIA CES for AIA members upon completion of the AIA/CES Session Participation Forms found in the back of this session room and online at www.BuildersShow.com. Certificates of Completion for both AIA members and non-AIA members are available upon request. This course is registered with AIA CES for continuing professional education.

  6. 6. Myth Busters “We don’t have time for that.” “Sustainability people just don’t understand construction issues.” “The process is WAY too restrictive.” “Certification is just too expensive.” “The builder will totally lose control of the project.” “Just meeting the energy code is hard enough.” “All certifications require solar panels.” “All materials would be more expensive.” “$$$$$.” “We would have to deal with the Green Police.” “$$$$$.” “$$$$$!!!”“Too many surprises!” “Too much risk.”
  7. 7. WHY CERTIFY?
  8. 8. Internal Drivers • QA for long-term owners / durability • Builder/owner recognition • Accountability and 3rd party review • Save energy and energy costs • Attract tenants • Add value to building
  9. 9. External Drivers • Municipality required • Special design agreements • Expedited review and variance potential • Impact fee reduction • Investors, purchasers and/or lenders • Tax credits and deductions • NEW: Mortgage insurance premium reduction
  10. 10. Preferential Lending for Green Multifamily Projects
  11. 11. Translation: $1,000,000 Loan 50  25 MIP Basis Points: Saves $208 per month = $2,500 per year $10,000,000 Loan 75  25 MIP Basis Points: Saves $4,167 per month = $50,000 per year
  12. 12. 179D • Up to $1.80/sf • Difficult for multifamily 45L • $2000 per unit LIHTC • Low-Income Housing Tax Credits • Additional state benefits 25D (Renewable Energy) • Solar, Wind, Geothermal 2016 Tax Credits For New Construction What will we see in 2017??
  13. 13. PACE • Property Assessed Clean Energy • Finance improvements MACRS • Modified Accelerated Cost Recovery System (depreciation) Residential Efficiency • Tax credit of 10% of cost for upgrades 25D (Renewable Energy) • Solar, Wind, Geothermal Other $$ Benefits For Renovations What will we see in 2017??
  14. 14. • Low/no cost = willingness to partner • Existing programs • Blaze the trail • Expedited permitting review • Variances in density or height • Impact fee reduction Talk to your municipality!
