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.
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.
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.

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.”
WHY CERTIFY?
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
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
Preferential Lending for Green Multifamily Projects

HOW TO CHOOSE (What is the best fit for you?)
• Project identity and target market?
• Demands of lender or preferential lending program, municipality, etc.?
• Experience: Programs done in past?
• TOD? Urban infill? Suburban? Greenfield? Competing Properties?
• Affordable vs. Market Rate vs. Mixed Use?
• Free points – what do you already have? (or be recognized for?)
• Townhomes, Garden, Wrap, Podium, High-rise?

Building Codes
Things to think about
• Residential ventilation requirements
• Building tightness requirements
• Blower door testing and duct testing (2012 and
2015 IECC requires BD for low-rise)
• Will local code drive your energy baseline? Can
you beat it?
Air Quality
Residential Ventilation Differences
• Natural Ventilation Only is permitted:• NGBS
• Only if tested air-tightness is ≥ 5ACH @ 50pa
• Mechanical Ventilation is required:• LEED for Homes• LEED BD&C (New for LEED v.4 for R2 occupancy)• Energy Star for Homes• LEED Midrise• Energy Star MFHR (footnote #20 is gone)• EGC
• Exhaust-only OK in some climates
Your local code requirements will be a big driving factor!

• AEE (Association of Energy Engineers) – BESA – Building Energy Simulation Analysthttp://www.aeecenter.org/directory/
• RESNET Qualified professionalshttps://www.resnet.us/directory/search
Timeline and ProgressWhen is it too late?
A Smooth Path to CertificationDesign• Meet as whole
design team• Involve
Consultants • Iterative Process• Echo decisions in
writing for owner/architect for their approval
Documentation• Supply
inclusions• Plan review DDs
CDs and provide mark-ups and/or comments
• Specifications
Transition to Construction• OAC meetings
with site staff• Buy-outs• Informal
guidance narratives
• Overview of verification process
Construction• Meet with Sub-
contractors and site staff
• Provide overview of verification visits
• Provide reports to all stake holders after each visit
Cost Management(Nobody likes surprises)
Managing and Predicting Costs
• How to answer “How much does it cost?”
• Decision making process
• How to avoid team members arbitrarily inflating costs
• How to plan properly (to avoid abuse)
• Trade-ability and iterative process
Efficiency doesn’t have to be expensive!
• Passive house design
• Exhaust cfm/watt
• Automation can be simple
• Variable or multi-speed systems
• Central fan – Energy recovery
