The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

bull502 Building Envelope ldquoUrdquo Factors and SHGC 50223
The U-value (or U-factor) more correctly called the overall heat transfer coefficient describes how well a building element conducts heat It measures the rate of heat transfer through a building element over a given area under standardized conditions
The Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from sunlight The SHGC is the fraction of the heat from the sun that enters through a window SHGC is expressed as a number between 0 and 1 The lower a windows SHGC the less solar heat it transmits

Code OverviewhellipOampMhellipestimated to save 5 to 20 on energy bills without a significant capital investment
In addition to energyresource savings a well-run OampM program will
bull Increase the safety of all staff as properly maintained equipment is safer equipmentbull Ensure the comfort health and safety of building occupants through properly functioning equipment providing a healthy indoor environmentbull Confirm the design life expectancy of equipment is achievedbull Facilitate the compliance with federal legislation such as the Clean Air Act and the Clean Water Act

Code OverviewhellipCommissioningCommissioning of existing buildings is critical to ensure energy efficient operation
Additional benefits include extended equipment life increased tenant satisfaction through improved space comfort improved indoor air quality and fewer OampM emergency calls
The reported average cost to recommission is usually in the range of $005SF to $040SF The simple payback period on these efforts is usually less than 2 years and quite frequently less than 05 year
