Abstract
Energy efficiency measures are different from energy
efficiency and cost effectiveness perspective. For decision
maker it is hard to make right decision about different energy
efficiency measure combinations in building. It is a complex
problem to choose the best energy efficiency measure
combination as decision involves many different factors that
should be taken in account. Decision on implementation of
energy efficiency measure implementation usually depends
on investment costs and pay back time. Standards like
Latvian Building Code LBN 002-01 can’t be used to achieve
reasonable expenses in renovation of buildings. Therefore, in
order to find the optimal energy-efficiency measures, it is
necessary to carry out optimization taking all the variable
parameters into account. In the paper target function was
presented that gives ability of the multi-objective
optimization approach to handle the problem of improving
energy efficiency in buildings. Case study is used to
demonstrate the feasibility of the approach. 104. series
soviet type dwellings was analysed to optimized insulation
thickness for external walls. Even if accord with the LBN
002-01 it is enough to use 7 cm thick isolation (λ-0,039
W/(m2K)) layers optimal insulation layer is 12 cm (λ-0,039
W/(m2K))
