2 - Blower Door Air Infiltration Testing

Blower Door Testing Air Leakage Rate: Overview of Blower Door Testing:

How a Blower Door Test Works:

A blower door can be used for air leakage testing or building thermal envelope testing. Blower door test equipment consists of a fan, an adjustable doorway block, a manometer, and hoses. The fan is set up in a doorway and sealed around the opening. All the windows, doors, flues, and vents (where applicable) are closed or sealed off during the test. The fan is run for a short period of time up to a certain pressure rating. At that pressure, the manometer will measure the amount of air moving through the fan in cubic feet per minute. A simple calculation with this number and the square footage of the home will give you the Air Changes Per Hour (ACH). The results of blower door testing will help determine whether air sealing of the home is recommended to help improve comfort and improve the energy efficiency of the home.

3.3.1 - Interior-Exterior Air Sealing

Can lights seal

Seal the recessed light fixtures in the home. The majority of the leakage present is occurring around the edge of the light, in the space between the drywall and the edge of the light can.  This gap needs to be sealed.  Seal around the edges with the trim and bulb are removed from inside the home, with an appropriate fire rated caulking.  The better alternative is to seal all these light fixtures in the attic, around the edges of the cans, adjacent to the drywall, where access is available in the attic.

OBSERVATIONS AND RECOMMENDATIONS:

The following items were Inspected and Observed, with any Recommended Actions noted:

Insulation and Ventilation Overview

The insulation is inspected where visible at basements, crawlspaces, attics, vaulted or finished ceilings, and at any wall or floor assemblies adjacent to the outside or garage spaces.  When not visible, some probing may be done, to try to determine cavity depth and whether or not insulation is present.  Infrared scans are also conducted, to ensure no significant voids or un-insulated areas are present.

Wall Insulation: No Concerns Noted

A basic inspection of the wall insulation was done using infra-red scans, and observing insulation levels behind outlet plates, where possible.  This limited inspection showed that the walls appear to be insulated well at this time.  No gaps, voids or missing areas were noted.

Garage Ceiling Insulation: No Concerns

The floors over the garage were viewed with Infrared and  appear to be adequately insulated, with no significant voids or gaps noted.

4.3.1 - Basement Insulation

Basement walls uninsulated

The concrete foundation walls are not insulated where visible.  This is causing the basement to be colder than the rest of the home.  I recommend adding fiberglass batt insulation, or vinyl faced fiberglass sheet insulation to the concrete walls where accessible.

4.4.1 - Crawlspace Insulation

Condition the crawlspace

Considerable air leakage is occurring at the crawlspace, and the floors above are noted to be colder than the floors in the rest of the home.  It is recommended that you consider converting this to become a conditioned crawlspace, which will improve energy efficiency and prevent moisture concerns.  To accomplish this, typically the following steps are taken: The vapor barrier should be installed to cover all of the soil, and the vapor barrier should be attached and sealed to the foundation walls along the perimeter, as well as sealed at all seams throughout the crawlspace.  Insulation should be installed at the rim joists and on the foundation walls to drape over the sealed edges of the vapor barrier.  Seal off the crawlspace vents to the exterior, and consider sealing at the exterior sill plates on the foundation where accessible to minimize air leakage.  An HVAC professional should also investigate installing a heat supply into the crawlspace, which will provide drying and air exchange. This will result in a somewhat conditioned crawlspace that will be less prone to air leakage and condensation occurring on the underside of the floor system from cold air entering in the wintertime.   Consult with an insulation or HVAC specialist to verify these recommendations and to determine other repair options.

8.3.1 - Temperature of Hot Water

Temperature setting

The water heater temperature setting is too high, and the water temperature was measured at >135F.   This will cause excessive energy use from the water heater. I recommend reducing the set-point to help reduce costs and save energy.  The Department of Energy recommends 120F as the optimum setting for efficiency.  See here for more details.

9.1.1 - Energy Efficient Lighting

Continue adding LED/CFL Bulbs

Currently, there are many LED or CFL bulbs in use in the home.  Continue to install LED's or CFL's in as many non-dimmed light fixtures as possible.  LED and CFL bulbs consume 1/4 the power of incandescent lights, and often last up to 10 times longer.  This will help to reduce your overall electric energy consumption.  For more information visit here.

9.2.1 - Fixtures, Switches, and Connected Devices

Smart strip

For entertainment center areas and computer system areas, I recommend that you consider using "smart-strip" power strips.  These devices use one device as the primary device, and completely remove power to all the secondary devices plugged into the power strip, when the primary or control device is turned off.  This removes the phantom or ghost loads that some devices have, where they continue to consume power even when turned off. Smart-strips are sold at local hardware stores and through on-line retailers.  An on-line resource for these products is www.tricklestar.com

10 - Appliance Review

Appliance Inspection Overview:

The appliances in the home are inspected to review their age and likely energy efficiency and performance.  General energy related recommendations are made to consider when replacing one of the appliances.

Refrigerator/Freezer: No Immediate Concerns
The refrigerator installed in the home is a newer style unit, and likely has acceptable power consumption.  No energy efficiency action is recommended at this time.
Clothes Washer/Dryer: No Immediate Concerns
The washer and dryer installed in the home are newer, front-load units and are in good condition.  No improvement action is recommended.

11 - Renewable Energy Options

Solar and Renewable Energy Options:

Opportunities exist with every home to add renewable energy products to help offset overall consumption.  We believe that the significant insulation, air sealing and equipment efficiency options to improve should be considered first.  After high priority concerns are addressed, options exist for installing renewable energy items, with specific recommendations below.
