An instrument is used to measure the level of air tightness the house maintains, diagnose any air leakage problems, estimate natural infiltration rates, and gauge efficiency losses due to home air leakage.
The Blower Door Test is used to measure the amount of air a home may be leaking through exterior doors and windows, resulting in wasted energy and higher utility bills.
The Importance Having of This Test
The Blower Door Test test diagnoses and measures air leakage, estimates natural infiltration rates and efficiency losses, and certifies construction integrity. Having this test will ultimately ensure a home’s air efficiency and save the owner money. This test is the top choice for utility programs, energy raters, HVAC contractors, builders, insulation contractors, and weatherization professionals.
Testing Procedures
The Blower Door Test is performed with all of the home’s doors and windows closed. An expandable frame fits the door opening, with a light fabric cover to block off the doorway, except for the fan. Then pressure gauges are used to take measurements. With this test we are looking to measure how much air a home leaks at a specified reference pressure. When the recommended repairs are made, the result is tremendous energy and financial savings.
What We Provide
LgO will measure the level of air tightness a home maintains to identify possible leaks. Our inspection results are provided to the customer, and recommendations on how to correct any problems are made. Repairs are then made by a contractor of the customer’s choice. At the customer’s request, LgO will make a follow-up inspection to ensure the repairs are within the energy efficiency recommendations.
An instrument measures air duct tightness, diagnoses leakage problems, and estimates energy efficiency losses from duct leakage.
The Duct Blaster Test measures and diagnoses air leakage problems within a home’s forced-air duct system.
The Importance Having of This Test
Air leakage in a home’s duct system can greatly increase heating and cooling costs - sometimes more than 30% - and can contribute to comfort, health and safety problems. Finding hidden air leaks can be next to impossible without the use of a Duct Blaster. A Duct Blaster is a fan and pressure gauge that pressurizes the home’s duct system and accurately measures turning air leakage within the duct work.
Testing Procedures
The Duct Blaster is connected to the return grill or air handler. All of the registers and/or supply grills are covered in order to create a closed loop in the system. The fan is turned on to 25 Pascals to balance the pressure in the duct system. Once the duct system is pressurized, it reveals any air leakage around the plenum area, the joints, and the flexes. Any duct leakage represents heating and cooling energy loss.
What We Provide
LgO will conduct the Duct Blast Test in order to identify possible leaks in the home’s duct system. The inspection results and any repair recommendations are provided to the customer. Repairs are then made by a contractor of the customer’s choice. At the customer’s request, LgO will make a follow-up inspection to ensure the repairs are within energy efficiency guidelines. A second inspection is required if the customer is requesting any applicable rebates from CPS Energy.
The Flow Hood Vent test is used to measure, to diagnose, and to demonstrate air leakage problems in the duct system and Air Balancing Defined.
The Importance Having of This Test In its simplest form, Air balancing is the process of testing and adjusting your air conditioning and heating system to deliver the right amount of air to each room in your home. The actual Air Balancing process includes a number of related tests that determine the performance of your air conditioning and heating system.
Testing Procedures
Air balancing hood are use to measure the amount of air at each grille, Manometers measure system static pressures, Hygrometers will measure system temperature and humidity and the result of all these test s are compiled into a report to determine how well your system is functioning.
What We Provide
LgO will inspect the duct system in order to identify possible leaks. A report is provided to the customer with the inspection results and recommendations. Repairs are made by the customer using a contractor of their choice. At the customer’s request, LgO can make a second inspection to ensure the repairs fall within the energy efficiency guidelines. The second inspection is required when the customer is requesting any applicable rebates from CPS Energy.
Thermal imaging is now the most effective procedure used to diagnose a structure’s thermal performance and capabilities. Thermal imaging identifies temperature variations of a building’s surface. This reveals many problems with energy conservation that are directly related to the structure of your home. Problems in your home’s structure including air leakage and moisture content which leads to mold growth can be found through thermal imaging. It will show areas of missing, non-existent insulation in walls and ceilings.
These services allow the customer to learn the true cost attributed to their daily use of appliances. We provide customers with diagnosis and recommendations regarding how to maximize the efficient use of household appliances.
Knowing the energy use of one’s home can save money and give the owner peace of mind. Audits consist of a visual inspection of the home and appliances. We analyze the energy efficiency and make recommendations to improve energy consumption. After analyzing the energy audit, we make recommendations on how to put as many of our suggestions into practice as possible and keep a record of how much energy is being saved.
COST OF OPERATIONS
It is also important to know how much appliances are costing the home owner. This allows the owner to make better choices on how to operate them more efficiently and which appliances are best when replacement is necessary.
What We Provide
LgO will provide the customer with an Audit Report and List of Recommendations to assist in conserving energy.
