Mungo Homes was named the National Green Advocate of the Year in 2012 by Builder Magazine.

    Q

    What factors are considered when calculating Average Annual Energy Savings?

    A

    A blower-door test is performed on each and every new home by an independent third party to measure air flow throughout the home. Energy-efficiency is calculated based on the overall air tightness of the home.

      Q

      Can anything affect Average Annual Energy Savings?

      A

      Actual energy costs will vary depending on individual usage habits, number of residents in the home and fluctuation in rates by your utility company.

        Q

        What is a HERS rating?

        A

        The HERS (Home Energy Rating Systems) rating provides a standardized evaluation of a home's energy-efficiency and expected energy savings.  The lower the HERS rating the more energy-efficient.  The typical code-built home has a HERS rating of 100.  A home with a score of 75 would be 25% more energy-efficient than a code-built home.  The rating is calculated by an independent third party who inspects and rates each and every new Mungo home. 

        (Think of a HERS rating like a golf score: the lower the better!)



          Q

          Why does Mungo use HERS instead of Energy Star to rate new homes?

          A

          The HERS index allows comparison to existing and code-built new homes.  Energy Star is a yes/no certification rather than an actual score of a new home’s energy efficiency.  The HERS index rates actual energy efficiency and estimated annual cost savings.

            Q

            What is “Advanced Framing?”

            A

            With traditional framing, the 3-stud outside corner space is boxed in and cannot easily be insulated, resulting in energy loss.

            With “Advanced Framing", a "California Corner" is a simple L-shape corner that allows easy access to install insulation, reducing air flow throughout the structure resulting in greater savings on heating and cooling costs.


              Q

              Explain Air Barriers & Air Sealing

              A

              Air leakage is the single biggest loss of energy in a home.  Mungo Homes include extensive air barriers to seal gaps and block random air movement through the new home. Air sealing controls moisture, prevents dirt and pollen from leaking inside the home, and reduces airflow throughout the home, thereby increasing indoor air quality and energy efficiency.

                Q

                What are the advantages of a tankless water heater?

                A

                Tankless water heaters provide an endless supply of hot water at just the right pre-set temperature.  The flow of water activates the system’s heating device, instantly heating a continuous supply.  There’s no holding tank so energy isn’t wasted on storing and heating water when it’s not needed, and its compact size frees up valuable square footage.  (Source: SCE&G)

                  Who is the “independent third party inspector?"
