Comprehensive Home Energy Assessments (Audits) – For existing buildings; a detailed site inspection of the building is made to determine window/door performance, insulation levels and effectiveness, HVAC equipment evaluation, lighting and appliance evaluation, CAZ testing, duct blaster and blower door results.  When Rem/Rate modeling option is chosen a floor plan and field take off form are completed and this data is then analyzed for building energy consumption.  Costs for possible energy efficient improvement measures are obtained and an assessment can then be made to determine which of the considered improvements are cost effective and offer the greatest savings to investment ratio.  Using the test-in/test-out model ECG can provide a full analysis of building performance prior to improvements and post improvements to document overall impact of any energy efficiency retro-fits and the related savings realized.

Plan Review Analysis –  The  plan review process lets the builder know whether or not the proposed home meets the requirements to qualify for the Energy Star program as well as state energy code requirements and give us the opportunity to make recommendations to improve the homes energy efficiency.  Energy efficiency and savings can be determined and demonstrated through use of a performance based software program.

Diagnostic Testing – Thru diagnostic testing the energy efficiency of a building can be verified.  This testing includes envelope air tightness by means of blower door test, duct leakage by means of duct blaster test, air balance and flow verification by means of flow hood test and thermal envelope integrity by means of thermal imaging.  In, case of gas fired appliances being located in the conditioned space combustion appliance safety (CAS) testing can also be provided.

Field Inspections – Inspections including site verification of Insulation values, Window U-Values and Solar Heat Gain Co-efficient (SHGC), Appliance energy efficiency ratings, Mechanical Equipment energy efficiency and sizing, Verification of lighting efficiency and completion of the Energy Star Program required Thermal By-Pass Inspection Check list.  The referenced field inspections help determine whether the home truly complies with the Energy Star Program and assists the builder with quality assurance.

Education – Energy Conservation Group, LLC provides training for builders, sub-contractors, homeowners, material manufactures, etc. on energy efficiency methods and measures.

Energy Efficient Mortgage Certification – An energy mortgage is a mortgage that credits a home’s energy efficiency in the home loan. Homes in which the energy efficiency can be improved allows the money saved in monthly utility bills to finance energy improvements.  There are two types of energy mortgages:
•    Energy Improvement Mortgage – Finances the energy upgrades of an existing home in the mortgage loan using monthly energy savings.
•    Energy Efficient Mortgage – Uses the energy savings from a new energy efficient home to increase the home buying power of consumers and capitalizes the energy savings in the appraisal.

Weatherization Assessments –  Energy Conservation Group, LLC has many years experience evaluating existing single family homes and multi-family buildings for existing energy efficiency and assessing energy efficiency improvement measures as to savings to investment ratio, simple back, etc.

Air Leaks
Leakage accounts for the majority of your homes’ energy losses.  As part of a Comprehensive Home Energy Assessment a blower door test is performed on the building envelope to determine the volume of leakage in the building envelope.  This test will diagnose any problem areas of excessive leakage between the envelope and the outdoors, as well as identify any potential indoor air quality issues in the building.   A plan of action for sealing envelope leakage can be made.
Duct Leaks
Ductwork carries the air that you are paying to heat and cool throughout the house.  The national average for duct leakage is 30%.  Imagine if 30% of the gas that you pumped into your car leaked out onto the ground.  That is what is most likely happening in your duct system.  Our diagnostic equipment (duct blaster) can measure the amount of leakage and help track down where those leaks are occurring.

An independent Energy Assessment (Audit) will ensure an unbiased evaluation of your home.  Our goal is not to sell you a product but to help educate you about your home and help map out a plan to save money, increase comfort and ensure the health and safety of you and your family.
