“…A far more comprehensive analysis is provided by Jakob (2006). While this refers to renovations in Switzerland rather than Germany, it is useful for comparative purposes because weather conditions, building infrastructure and building codes are similar in the two countries (though costs differ).…”

“…In contrast to Enseling and Hinz, who monitored the actual thermal performance of dwellings post-renovation, Jakob (2006) estimates performance using standardised thermal transmission values for the various techniques and standards of thermal renovation undertaken. Further, Jakob (2006) uses the measure of marginal, rather than absolute, costs. This enables him to make meaningful comparisons without knowing the pre-renovation energy consumption of the buildings.…”

“…Enseling and Hinz, 2006), though some studies estimate different lifetimes for different aspects of the renovation (e.g. Jakob, 2006;Großklos, 2008). Secondly, we need to decide how to value energy saved in future years, compared to that saved today.…”

“…While this refers to renovations in Switzerland rather than Germany, it is useful for comparative purposes because weather conditions, building infrastructure and building codes are similar in the two countries (though costs differ). Jakob (2006) brings together the actual costs of a large representative sample of thermal renovations of existing homes during the decade 1993-2003.

Terms of use: Documents in ISSN 0967-8875 AbstractOne of the cheapest ways to reduce CO2 emissions is thermal renovation of existing homes. Germany is a world leader in this project, with a strict building code, generous state subsidies, and an advanced renovation infrastructure. The effects of its policies are explored here in the light of progressive tightening of the building code, and the strict criteria for subsidies. Data on costs and outcomes of residential building renovations are presented from published reports on renovation projects, and cross-checked with projects investigated directly. Comparisons are made in terms of euros invested for every kilowatthour of heating energy saved over the lifetime of the renovations, for standards ranging from 150 (the lowest standard) to 15 (the highest) kilowatt-hours of primary energy use per square metre of floor area per year. It is found that the lowest standard is an order of magnitude more cost-effective than the highest, in terms of both energy saved per euro invested, and return on investment over the lifetime of the renovations, regardless of fuel prices. It is argued that this throws into question Germany's policy of progressively regulating for higher renovation standards, and offering subsidies only for projects that go beyond the minimum standard.

Assessment of the economic efficiency of energy‐saving projects, methodology based on simple and compound methods

Among different engineering projects, there are ones intended to improve the energy-saving properties of buildings. Both new and much older buildings undergoing refurbishment can be involved. Broadly understood energy-saving projects increasingly often entail renewable energy installations. Every implementation of such an investment project needs to be preceded by an assessment of its economic efficiency. Although the literature provides examples of methods which can serve this purpose, a coherent methodological approach seems lacking. In this article, the author proposes methodology based on several simple and compound methods combined into a schematic assessment procedure. The methodology is presented as applied in a case of typical photovoltaic roof installation to generate electricity for a single-family house. The assessment procedure consists of a few steps leading from a preliminary to a more detailed appraisal. The first stage is an How to cite this article: Szafranko E.
