Standards and Test Procedures | Department of Energy
Standards and Test Procedures. The Department of Energy (DOE) establishes energy-efficiency standards for certain appliances and equipment, and currently covers more than 60 different products. Authority to undertake this effort was granted by Congress, and DOE follows a four-phase process when reviewing existing and developing new standards.
Residential HVAC Installation Practices
Key findings include: air-conditioner use in single-family residences currently accounts for 17–18% of peak demand, and improving equipment efficiency alone could save up to 205 MW, or 8%, of peak demand. The study estimated 31% of systems were oversized, leading to up to 41 MW of excess peak demand.
Preventative Maintenance for Commercial HVAC Equipment | Better Buildings Initiative

Home Energy Assessments | Department of Energy
Home Energy Assessments. A home energy assessment, also known as a home energy audit, can help you understand the whole picture of your home''s energy use, comfort, and safety. An assessment can help you determine how much energy your home uses, where your home is inefficient, and which problem areas and fixes you should prioritize to save ...
Residential HVAC Installation Practices
Duct leakage is the most common source of performance degradation of HVAC systems, with most studies finding 90-100% of systems tested needing sealing or repairs to the supply or return air ducts. Low airflow is found more than 50% of the time in all regions studied, while high airflow is a problem in 8-15% of systems.
Experimental study of R290 replacement R134a in cold storage air conditioning …
The optimal charging amount range of the R290 cool storage air conditioning system is 500–600 g, and the optimal value is close to 600 g. Under the condition of a similar cold storage effect, the charge of R290 is only 43–46% of R134a. 4.3. The system performance under the optimal charge amount.
Prediction of virtual energy storage capacity of the air-conditioner ...
Smart virtual energy storage system is developed by using demand response management • Regression based artificial neural network (ANN) model is proposed to predict the discharging capacity of aggregated air-conditioners. Stochastic gradient descent optimization algorithm is implemented in a back-propagation network to …
Energy storage
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential ...
