SPI Go Green LLC is a nationally certified Home Energy Rating company that provides ENERGY STAR® certification for new homes, weatherization program for existing home, consultation for energy improvement in residential application and plan and layout analisys in pre-construction phase.
SPI Go Green LLC is a member of RESNET and can performe the following services:
ENERGY STAR® for new home
To earn the ENERGY STAR, a home must meet guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes are at least 15% more energy efficient than homes built to the 2004 International Residential Code (IRC), and include additional energy-saving features that typically make them 20–30% more efficient than standard homes.
With the help of SPI Go Green LLC as independent Home Energy Raters, ENERGY STAR builder partners choose the most appropriate energy-saving features for their homes. Additionally, SPI Go Green LLC conduct onsite testing and inspections to verify the energy efficiency measures, as well as insulation, air tightness, and duct sealing details
Weatherization Analisys for existing home
Weatherization Analisys are cost-effective energy efficiency measures for existing residential and multifamily housing. Under this definition, it includes a wide variety of energy efficiency measures that encompass the building envelope, its heating and cooling systems, its electrical system, and electricity consuming appliances. In other words, the full range of energy efficiency measures in buildings that apply to all homes and apartment buildings is included in the weatherization analisys.
Plan and Layout analisys
SPI Go Green LLC can perform an analisys of your plan and layout and conduct a project home rating before you build the house. After the projected rating, raccomandation will be privide to reach the goal and standard set by Energy Star program or your personal goal.
Onsite testing and inspections will be perform during the costruction phase to verify the respect of the standard and a final rating will be run to conferm the projected rating value.
Testing Services
Leakage in the HVAC system:
Duct Blaster Test: To address the hot and cold spots of your home, as well as any possible heating or cooling loss through the duct system, we perform a Duct Blaster Test. This test locates any problem areas and quantifies the extent of the leakage. Once the source of the leak has been pin-pointed, remedial actions can be undertaken to seal the duct system.
Leakage in the Building Envelope:
Blower Door Test: This test quantifies the amount of leakage in the home’s envelope. In short, it locates holes and leaks in the home by depressurizing the building. It also aids in finding air barrier and insulation flaws.
Consumer Information
Buying a home or investing in upgrades to an existing home involves is a series of critical, important decisions. The cost of heating and cooling a home is the highest cost of homeownership outside of the mortgage loan. Everyone wants a home that is comfortable and affordable. Knowing the home's energy performance is a critical piece of information you need when selecting or upgrading a home. A home energy rating will educate you about the condition of a home's energy performance.
Home energy ratings provide a standard measurement of a home's energy efficiency. Ratings are used for both and new and existing homes. In new homes, ratings often verify energy performance for the ENERGY STAR homes program, energy efficient mortgages, and energy code compliance. Homeowners who want to upgrade the home's energy efficiency can use the energy rating to evaluate and pinpoint specific, cost-effective improvements. For existing homes, homeowners can receive a report listing cost-effective options for improving the home's energy rating. An energy rating allows a home buyer to easily compare the energy performance of the homes being considered.
Choosing a RESNET rater member means that you are selecting someone you can trust to objectively provide you with a comprehensive analysis of the home's major energy systems and components.
RESNET rater members are trained and have demonstrated technical proficiency and have committed to maintain and improve their technical proficiency through continuing education.
Members are committed to conducting ratings in accordance with the RESNET Rating Standards of Practice; abiding by the RESNET Rating Code of Ethics, and disclosing any financial interest in the home being rated. Through their membership to RESNET, member raters demonstrate their commitment to technical and ethical quality.
What is a HERS Rating?
A home energy rating involves an analysis of a home’s construction plans and onsite inspections. Based on the home’s plans, the Home Energy Rater uses an energy efficiency software package to perform an energy analysis of the home’s design. This analysis yields a projected, pre-construction HERS Index. Upon completion of the plan review, the rater will work with the builder to identify the energy efficiency improvements needed to ensure the house will meet ENERGY STAR performance guidelines. The rater then conducts onsite inspections, typically including a blower door test (to test the leakiness of the house) and a duct test (to test the leakiness of the ducts). Results of these tests, along with inputs derived from the plan review, are used to generate the HERS Index score for the home.

The HERS Index is a scoring system established by the Residential Energy Services Network (RESNET) in which a home built to the specifications of the HERS Reference Home (based on the 2006 International Energy Conservation Code) scores a HERS Index of 100, while a net zero energy home scores a HERS Index of 0. The lower a home’s HERS Index, the more energy efficient it is in comparison to the HERS Reference Home.
Each 1-point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to the HERS Reference Home. Thus a home with a HERS Index of 85 is 15% more energy efficient than the HERS Reference Home and a home with a HERS Index of 80 is 20% more energy efficient.
