Insulation protection studies for energy saving in residential and tertiary sector

摘要

Thermal insulation studies for a private residence, built before the enactment of the Thermal Insulation Code in Greece, is descried in this paper. Various insulation protection approaches for the same buildings envelop, which is situated in the city of Kavala in Northern part of Greece, are investigated. A performance compariosn of these technial approaches, concerning cost and energy saving issues, is given. The cost estimation is performed as a function of insulation material used, the labour and insurance cost. The energy saving is evaluated by comparing the energy consumption (in kW h) for space heating before and after the application of thermal insulation in the structure envelop. Finally, useful conclusions were also drawn regarding futher steps towards the rational use and energy save in newly erected buildings.
