Economic Analysis for Green Residential and Non-Residential Building Envelopes

Abstract

Renovating buildings is more useful than ever. Due to future rising energy prices, energy costs in poorly insulated buildings are an important component of operating costs. Another important point is the rapidly growing emissions from the combustion of fossil energy sources. Good insulation in buildings reduces the amount of primary energy and thus, less greenhouse gases are emitted. The renovation potential is high. A large part of the properties consumes more energy than would actually be necessary. Common construction without thermal insulation is responsible for this. It is advisable to invest in renovation, also, in thermal insulation. This will benefit you in two ways. The ancillary (additional) costs will be reduced massively, the living comfort increases and by today's state subsidies in many countries they will make a contribution to the investment costs.
