    Sammanfattning : Reliable evaluation methods is needed to ensure that investments in energy conservation measures (ECMs) and the construction of new energy efficient buildings lives up to the promised and expected performance.This thesis presents and evaluates a regression method for estimation of influential building parameters: transmission losses above ground (including air leakage), ground heat loss, and overall heat loss coefficient.

  2. 2. Improved building energy simulations and verifications by regression

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Jimmy Vesterberg; Umeå universitet.; [2016]

    Sammanfattning : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users. LÄS MER
