Baseload Analysis

Baseload Analysis – High utility bills? Are you appliances ENERGY STAR rated? Do you use incandescent bulbs?

Utility bills are the scorecard for the energy specialist and the consumer. An analysis is completed based on the 12-month history for electric and gas usage to determine the baseload consumption. Baseload is defined as your energy usage from all sources except heating and cooling. These costs vary only slightly from month to month versus seasonal consumption that is dependent on the outside temperature for your heating and cooling. From the utility bill information and the interview process we can begin discussing what behavioral changes will benefit you from a money savings, comfort, health and safety standpoint.

Exterior Inspection

Exterior Inspection – Full sun exposure? Cracks or penetrations visible?

There are three categories to document information during the exterior walkthrough: Building Shell, Windows & Doors and Air Leakages.

The building shell is any part of the building that creates a boundary between the indoor and outdoor space such as walls, roofs, doors, and windows. Fenestrations, or windows and doors, are looked at as a source of heat gain or loss rather than a source of air leakage, which is a less important energy consideration. Air leakage is detected where conditioned air leaks out of cracks, openings, penetrations, etc. and unconditioned air seeps in.

The Energy Advisor will look at all of these areas to determine if there are any durability issues that may affect energy performance.

Interior Inspection

Interior Inspection – Do you have can lights? Are there cracks or penetrations visible?

The interior walk-through documents the air barrier, which is any airtight surface that stops moisture in the air from entering the building. Examples of good air barriers are stucco and plaster because they are continuous and airtight; drywall and plywood are also good air barriers. The vapor barrier is also documented; this is a material that resists water-vapor diffusion through the surfaces of the building shell.

Thermal Boundary

Thermal Boundary – Do you have missing or inadequate insulation?

The thermal boundary is defined as a line or plane where insulation and an air barrier exist to resist the transfer of heat and air leakage through or within the building shell. The Energy Advisor will document the type and existing condition of the insulation found in the building.

Cooling/Heating Performance

Cooling/Heating Performance – Is your home staying cool in the summer and warm in the winter?

According to the U.S. Department of Energy, heating and cooling account for 56% of the energy use in a typical U.S. home, making it the largest energy expense for most homes. The Energy Advisor will evaluate the heating, cooling and water heater performance for efficiency and durability.

Combustion Analysis

Combustion Analysis – Do you have any gas leaks?

This inspection covers the safety and efficiency of gas furnaces, water heaters, and appliances. The testing involved uses a Gas Leak Detector, a Carbon Monoxide (CO) Monitor, and a Combustion Analyzer. The health and safety of the occupants is our number one priority. If the ambient levels exceed 35 ppm, the testing is aborted and the home is evacuated. The problem must be corrected prior to completing the combustion safety diagnostic.

Building Enclosure Performance (Blower Door)

Building Enclosure Performance (Blower Door) – Does your house breath right?

Blower Door testing provides a diagnostic assessment of air leakage using a fan, removable panel, and gauges. Air leakage occurs when conditioned air leaks out of a home through cracks and openings and unconditioned air seeps in. For every 1 cubic foot of air that enters a building, 1 cubic foot of air must exit. The main goals of air leakage control are to:

  • Save energy
  • Increase comfort
  • Protect insulation’s thermal integrity
  • Reduce direct cooling or heating of people and building components by outdoor air
  • Avoid moisture migration into building cavities

Infrared Camera

*Infrared Camera – Would you like to see the problem areas in your home?

The use of an infrared camera compliments the testing by pinpointing problem areas that may not be detected by any other means. This camera can detect subtle differences in temperature; this helps identify missing insulation, air leakage around windows and doors, and other areas of infiltration.
