A comprehensive HERS rating, conducted by a certified rater from Home Energy Solutions, Inc. is the most in-depth energy performance assessment of a home that you’ll find. It consists of several inspections along the course of construction to address any potential issues, along with diagnostic testing using specialized equipment, such as a blower door test, duct leakage test, combustion analyzer and infrared cameras to determine:
- The amount and location of air leaks in the building envelope
- The amount of leakage from HVAC distribution ducts
- The effectiveness of insulation inside walls and ceilings
- Any existing or potential combustion safety issues
HERS Rating is required on new construction in many towns throughout New York and the entire Country. Home Energy Solutions, Inc. is certified and trained to perform ALL inspections and testing required to achieve a HERS rated house.
ACCA’s Manual J is the first step in the design process of a new heating and air conditioning system. By following the Manual J methodology and most up-to-date software, Home Energy Solutions, Inc. is able to accurately determine the exact size system needed that will cool and heat your home effectively and efficiently.
Manual S takes the load calculated by the Manual J and finds the specific Make and model of the Equipment needed to meet those loads.
Finally, the Manual D will design the entire ductwork to distribute the heating and cooling evenly and efficiently throughout the home. Including where each register will be placed in each room, and how much CFM of conditioned air is needed in each room to enjoy a comfortable home.
Home Energy Solutions has state of the art equipment to measure duct leakage commercially as well as residential. According to the upcoming 2015 Residential Energy Code, all new ductwork must be tested by a third party licensed technician. HES offers duct tests individually as a per-system-cost, or included as part of our HERS and Energy Star Packages.
Home Energy Solutions, Inc. offers a unique and invaluable service in infrared scanning. Advanced infrared technology allows for detection and identification of problems invisible to the naked eye. Additionally, infrared scanning provides physical documentation of problems that often go unseen during standard visual inspections. Infrared thermography can identify a variety of issues and deficiencies:
1. Roof Failures
2. Comfort Issues
3. Moisture Detection
4. Heat and Air Issues
5. Insulation Verification
6. Electrical Damage
7. Mechanical Equipment Hot Spots
Infrared thermography is an effective way to ensure the stability and longevity of a home and to protect against greater costs incurred by major building failures. A thermographic inspection is either an interior or exterior survey. The energy auditor decides which method would give the best results under certain weather conditions. Interior scans are more common than exterior scans because there is less interference from outside conditions such as the sun warming a surface or heat loss, which may not be the source of the problem.
Thermographic scans are also commonly used with a blower door test running. The blower door helps exaggerate air leaking through defects in the building shell. Such air leaks appear as black streaks in the infrared camera’s viewfinder.
Infrared scaling allows energy auditors to check the effectiveness of insulation in a building’s construction. The resulting thermograms help auditors determine whether a building needs insulation and where in the building it should go. Since wet insulation conducts heat faster than dry insulation, thermographic scans of roofs can often detect roof leaks.
In addition to using thermography during an energy audit, you should have a scan done before purchasing a house; even new homes can have defects in their thermal envelopes. You may wish to include a clause in the contract requiring a thermographic scan of the house. A thermographic scan performed by a certified technician is usually accurate enough to use as documentation in court proceedings.
