Building Efficiency Calculations etc

    I'm currently looking at calculations which can be done on my house to quantify different energy efficiency levels, both for the current state and a proposed state.

    I've grouped them into what I believe are logical sections;

    1. Air Pressure Testing - air changes per hour etc.
    2. Thermography - not so much a calculation, bit an indicator of changes or weak points in fabric, i.e. differing U-Values for details etc
    3. Heat Loss Calculations - heat loss from pipework?
    4 . U-Value Calculations - Fabric calcs etc.
    5. Energy Use Calculations - perhaps appliances, lighting etc.

    I'm just wondering if I'm on the right track, and what specific calculations can be done (i.e. UA Value etc.) to quantify best the inefficiencies of the fabric and heating systems and anything else I might be overlooking.

    Thanks

    why not employ an arch with PH/ BER experience, also see the following:

    you need a PHPP done. it will do all the important calcs allowing you to make the proper informed decisions for your build. There is some people here who do them.

    Probably should have said that this is for a report for college, and I'm basically looking for an idea on what type of calculations could be done for each of the sections outlined in the op.

    Nope, sorry but we dont do college projects, thesis, surveys etc etc etc.

    Thread locked.
