PREPARE YOURSELFWho Will Manage This For You?
What is their experience level? • Energy Conservation• Green Resources
Training opportunities• Florida Solar Energy Center• Green Building Certification programs
FSEC overview and comprehension
WHAT WERE WE THINKING?
Phase 1 - not “Energy Star”, just affordable– Weatherization training prepared us for proper sizing of HVAC
and optimizing or “gaming” the software.
Phase 2 - retrofitted to meet “Energy Star”.– Cost upgrades split with the builder, in return for his tax credits
Our first focus was low maintenance and quality construction. Low utility bills were important.
Our “Energy Star” education began with the energy rater who argued the importance of Cost vs. Value of Energy Star upgrades
- What were the simplest cost effective measures?
• Windows, HVAC sizing, insulation
- Increased marketability – low utility bills and indoor air quality- “verified”

PARTNERSHIPS ARE KEYSTRENGTHS AND WEAKNESSES
Who do you need? A builder with an interest in affordable housing An Architect- with similar experience Local government- How will they help? Energy rater, FYN representative Identify housing programs that will support your
efforts:1) At what stage can the program help?2) What threshold requirements from the
programs?

PARTNERS
Who leads the design discussions? Find a builder who is creative, has an interest in
affordable housing and a good business background - unless you do
Find community partners with related interests: – University of Florida Extension Service
– Pedro Menendez High School masonry program
– Local government Housing Office

WHAT’S IN IT FOR THEM? WHAT DO THEY EARN?
Ask yourself: What does each of the partners need?– Fee for service - inspection fees or construction earnings– Publicity - recognition of program services
What do they (including you) do for the partnership?– Who carries the risk of building? – Who is responsible for financial management of the
project? – Who finds and educates the home buyers? – Who makes final design changes?
ENERGY RATER Find an “Energy Star” rater who has a
background in construction– There is a learning curve. Must build trust with
the builder and subcontractors– Energy Star construction is at a higher
performance level - it produces a better product - but it may not be “the way we have always done it”
– Clarify potential benefits - for builder and buyer

ENERGY STAR BENEFITS
Energy Efficient mortgage - produces the form for your lender
1st Step in Green Building certification Training in construction techniques-long term
value for construction partners 3rd Party construction inspections- quality
assurance - “building to code” may not meet energy star- pre and post construction help
Possible tax credit for builder

BENEFIT TO BUYERS
Our Energy Star ratings adds $6,500 to the appraised value (with only a $3,500 investment from us)
Energy efficient mortgages help the buyer to qualify, if needed
Energy and Water Conservation - long term utility cost savings for the buyer
Improved Indoor Air Quality / Reduced Call Backs
Problem: Getting Appraisers to recognize green/or Energy Star
improvements- value must meet sales price

GETTING THE “GREEN” IS ALL ABOUT THE SCORE
The rater inputs your plans and related material choices
“It’s one big math problem” For Green certification (the Florida Green Building
Coalitions' checklist), we earn more points with lower Energy Star rating.
We experimented with various material changes ( and the respective cost differences)to see the impact on the energy score.
Sustainable Development- storm water design and FYN landscape score well

“FIRST GREEN CERTIFIED HOUSE
IN ST JOHNS COUNTY” “Green starts with Energy Star Blue" Affordable first. Low maintenance construction,
energy and water saving measures were all selected to keep the homeowners maintenance costs low.
With a strong HERS score, water conservation and hurricane shutters, we met our green score.
We used very little “green” products; no green paint, no green carpet, no green wood and no solar. If it would add more cost, was it necessary?

PRODUCT SELECTION
Windows:
House sitting (north/south/east/west) determines window specs: a higher solar co-efficient rating
Insulation: R-Value and installation techniques fiberglass, cellulose, or foam
Dual flush toilets/faucet aerators - for water conservation "Florida Friendly Yard” - drought tolerant landscaping NAHB (National Green Building Standard) -
Provides one list of acceptable (certified) products

IMPROVEMENTS
Downsizing our 2 ton HVAC system to a 1.5 ton with a variable speed motor- increases SEER
Move the ducts from un-conditioned to semi-conditioned space. 1st - Create an attic chase over the AC ductwork, 2nd - Open Cell foam under roof
Experimented with insulation - blown and batt fiberglass, open cell foam and blown cellulose. Installation technique was more critical than type
Installed Energy Star bath exhaust fans - improved humidity control
