FAQ's
How long is ENERGY STAR certification?
Most products that have earned the ENERGY STAR label are certified for a period of two years. Some product categories have different certification periods. For example, computers and monitors must be recertified every three years to maintain their ENERGY STAR status.
What makes a building ENERGY STAR certified?
To earn the ENERGY STAR label, a building must perform in the top 25 percent of similar buildings nationwide for energy efficiency and meet strict energy efficiency performance standards set by the U.S. Environmental Protection Agency (EPA). ENERGY STAR certified buildings use an average of 35 percent less energy than typical buildings and generate 35 percent fewer greenhouse gas emissions.
Do you test each unit individually?
Yes—our team provides thorough testing and reporting for every unit and shared area, per code requirements. We will follow batch testing if the municipality of the project is in agreement with it.
What does it mean to be ENERGY STAR qualified?
To be ENERGY STAR qualified means that a product meets or exceeds the energy efficiency guidelines set forth by the Environmental Protection Agency (EPA). Products that are ENERGY STAR qualified use less energy, which can save you money on your energy bill and help reduce your impact on the environment.
How do you coordinate testing on large projects?
We collaborate with your superintendents and project managers to schedule testing efficiently and avoid delays.
Can you help us qualify for Energy Star Certification?
Absolutely—we handle all required inspections and documentation to help you earn certification and incentives.
