WHAT WAS OUR GOAL?

Our initial focus was low maintenance and quality construction. Low utility bills were importantOur “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 KEY

Who do you need? A builder with an interest in affordable housingAn Architect - with similar experienceLocal 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?

STRENGTHS AND WEAKNESSES

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 doFind 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?

PRODUCT SELECTIONWindows:

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

IMPROVEMENTSDownsizing 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 AC ductwork or 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
