Florida Housing Coalition

Annual Conference

September 2012

NSP PROGRAM BACKGROUND

$ 3,296,917 in funding provided by Martin County

23 units of housing purchased

Average rehab cost/unit = $ 35,304.58

U.S. DEPARTMENT OF ENERGY

WEATHERIZATION PRIORITY LIST

1. Air Sealing and General Heat/Cooling Waste – seal openings to prevent waste. Addresses air-infiltration: weatherstripping, caulking, thresholds. Including other required measures such as Water Heater Tank Wrap, Water Pipe Insulation, Faucet Aerators, Low Flow Shower Heads, HVAC Filters.

2. Attic Insulation – installation of insulation (to improve to minimum R-30)

3. Dense-Pack Sidewall insulation – installation of insulation

4. Solar Window Screens – installation of solar window screen

5. Installation of Smart Thermostat for central heating and cooling systems

6. Compact Fluorescent Lamps (CFLs) – replace incandescent bulbs with CFL’s

7. Seal and Insulate Ducts – seal central heating and cooling system duct work

8. Refrigerator – replace inefficient refrigerators

9. Addressing heating/cooling system – repair, upgrade and or replace inefficient systems

10. Hot Water Heater – replace inefficient hot water heaters

STARTING SMALL

Upgrade all lightbulbs (indoor and outdoor)to CFLs

Average cost $ 100 per home

Projected savings based on average home (30 bulbs):

$ 1,124 over the life of the bulb (7 years)

$ 177 annual electric cost savings

WATER SAVINGS To reduce water consumption in the bathroom by up to 50%:

Total cost: $ 134

Annual Savings: $ 80*

Upgrade: Cost:

Install an aerator on the faucet, rated to 1.5

GPM or less

$ 4.00

Install a Low Flow Showerhead, rated to 2.5

GPM or less

$ 30.00

When replacing a toilet, upgrade to Energy

Star rated dual flush, 1.6 GPF

$ 100.00 upgrade

GPM = Gallons per minute GPF = Gallons per flush

MAKE SURE EVERYTHING IS SEALED

Have contractor inspect and seal AC ducts whenever new ducts

are not being installed. Improperly sealed ducts and connections

can result in up to 20% air loss

Inspect all windows that are not being replaced to determine if

they need to have new caulk applied

Inspect weatherstrip around all entry doors for replacement need

Insulate electric outlets and switch plates

Insulate the back of the attic access panel and weatherstrip the

opening

INCREASING EFFICIENCY OF WINDOWS

SHGC, or the Solar Heat Gain Coefficient, measures how well a window blocks heat

from the sun. The lower the number, the more efficient the window.

Option: Cost per window:

Replace window with impact window,

tinted, SHGC .27 or less

$ 500.00

Replace window with standard window,

tinted, SHGC .26 or less

$ 340.00

Install solar screens on each window $ 120.00

Install window tint with a maximum

FHGC rating of .45

$ 75.00

Caulk around existing windows $ 60.00

INCREASING EFFICIENCY OF DOORS

Option: Cost per door:

Exterior doors, Miami Dade rated $ 470

Apply weatherstrip to existing door $ 100

A pair of exterior doors with no weather stripping can

have an opening of ¼” where the doors meet

On a 6’8” high pair of doors, this is equivalent to a 20-

square inch opening

A 20-square inch hole could allow over 40 cfm into or out

of the building

This air infiltration could cost up to $54/year in heating

and cooling costs

APPLIANCE PACKAGES

Refrigerator (Energy Star): $ 905

Range/Oven (Self Cleaning): $ 595

Dishwasher (Energy Star): $ 473

Vent Hood (Energy Star): $ 239

Washer (Energy Star): $ 609

Dryer (Moisture Sensor): $ 593

Total Cost: $ 3,414

AIR CONDITIONING

Install a programmable Smart Thermostat on any system Lowers heating/cooling bills by up to 10% and costs under $ 50

Relocate air handlers from attic to conditioned space on the main floor where possible. Air handlers draw 30-60 CFM of air from their surroundings via leakage from the cabinet.

Upgrade from code required SEER 13 HVAC to a more energy efficient level. SEER is the Seasonal Energy Efficiency Ratio which indicates the relative amount of energy needed to provide a specific cooling output

*Upgrade cost varies by manufacturer and installer, but averages $ 300-500 per SEER

Upgrade to: Upgrade Cost*:

(2.5 ton system)

Annual Savings

(from FPL)

SEER 14 $ 400 $ 40

SEER 15 $ 800 $ 90

SEER 16 $ 1,200 $ 120

ATTIC INSULATION

Insulate Attic to R-38: $.76 per square foot

$ 912 for a 1200 SF home

A properly insulated home can reduce heating

and cooling costs by 20% and overall energy

usage by 10%

SOLAR HOT WATER HEATERS

Average Cost: $ 5,000

Savings: $ 420 per year

CHOOSING PAINT FOR ITS GREEN VALUE

Light Reflectance Value (LRV) represents the percent of light

reflected off a surface

Dark colors absorb light and make a home hotter - LRV of 0 (Black)

absorbs all light

Light colors reflect light and keep a home cooler - LRV of 100 (White)

reflects all light

Paint colors with an LRV value of 50% or higher are recommended to

reduce energy costs

Volatile Organic Compounds (VOCs) are present in some paints.

These are unstable, carbon-containing compounds which can affect air

quality and pose health risks

Choose low or zero VOC paint to reduce these risks

LANDSCAPING

Shade the walls and windows of the house to reduce solar heat

gain, especially on the south side.

A 6-8 foot deciduous tree planted near the home will begin shading

windows the first year and shade the roof in 5–10 years.

Slow growing trees often have deeper roots and stronger branches and are

less prone to breakage during a windstorm.

Shade on the A/C compressor will help it work easier

Use drought tolerant plants to reduce irrigation requirements

3 Oak Trees planted on south side, cost $ 400 each

CASE STUDY

Duplex in Stuart, FL

CBS Construction built in 2004

Each side is 1,131 SF of living area

Last full year of occupancy, unit used 13,960 kWh annually

Remodeled with NSP funds, including:

Increase attic insulation from R19 to R38

New energy efficient windows with tinting

Solar hot water heater

All new Energy Star rated appliances and ceiling fans

Light reflective paint both inside and out

Current annual energy usage: 9,288 kWh – 44% less

Annual savings based on current FPL pricing: $ 606
