WINDOW UPGRADING PAYS OFF WITH WARM GLASS: 24MILLION RESIDENCES NEED TOO MUCH HEAT ENERGY [ALTBAUSANIERUNG. FENSTERSANIERUNG MITWARMGLAS RECHNET SICH: 24 MIO. WOHNUNGEN BRAUCHEN ZUVIEL WÄRME-ENERGIE]Résumé : The owners of about 24 million old buildings can quickly contribute to drastically decreaseCO2 emissions in Germany because they consume much more heat <strong>en</strong>ergy than necessary, accordingto the Interpane Glas Industrie AG. With the introduction of an "<strong>en</strong>ergy pass" and str<strong>en</strong>gth<strong>en</strong>ed useof support programs for heat insulation of older buildings the ambitious goal of the FederalGovernm<strong>en</strong>t to diminish CO2 emissions in Germany by 25% by 2005 (a goal established at the 1992Rio de Janeiro confer<strong>en</strong>ce) will be attained. Today over 50 million persons in Germany live in about24 million old buildings (built before 1982) that require too much heating <strong>en</strong>ergy. This is about 75%of the stock of resid<strong>en</strong>tial buildings. If "old construction" is defined in terms of <strong>en</strong>ergy use, th<strong>en</strong>about 95% of the buildings assault <strong>en</strong>ergy use. The modernization of these old buildings is urg<strong>en</strong>tlyneeded since in contrast to the new construction, such as 480,000 resid<strong>en</strong>ces erected in 1998, the<strong>en</strong>vironm<strong>en</strong>t can be more quickly relieved. Modern warm glass can, for example, in contrast toconv<strong>en</strong>tional insulation glasses, achieve up to 60% b<strong>et</strong>ter thermal insulation values. The use ofmodern windows with warm glasses, such as iplus neutral, quickly provi<strong>des</strong> savings. Two-paneinsulation windows have reduced the k value (heat transmission constant) of windows from about3.0 watts/square m<strong>et</strong>er-K in the 1970's to 1.1 and less today.Mots-clés : Buildings; Carbon dioxide; Construction; Glass; Heating; Heat <strong>en</strong>ergy; Thermal insulatingmaterialsHLH Heizung Luftung/Klima Haustechnik, vol. 50, N°10, 1999, pp.46-, [No author name available]Source interne à FCBA : base de données Scopus4.27 – SELECTION CRITERIA FOR ENERGY-EFFICIENT WINDOWSRésumé : Windows are a weak link in the thermal performance of a building <strong>en</strong>velope, and repres<strong>en</strong>tan important investm<strong>en</strong>t in the construction or r<strong>en</strong>ovation of any dwelling. This paper outlines somefactors which affect a window unit's <strong>en</strong>ergy performance and introduces g<strong>en</strong>eral guidelines for itsselection, installation and integration into a Canadian domestic dwelling. Significant reductions inheat loss using higher quality windows can achieve a payback period of 3.5 years.Mots-clés : Canada; Compon<strong>en</strong>t life cycle; Costing; Energy; Guidance for <strong>des</strong>igners; Heat losses;Housing; Payback period; Selection criteria; Warmth; WindowsFriedman A., Cammalleri V.Building Research and Information, vol. 25, N°4, 1997, pp.234-238, Friedman A., Cammalleri V.Source interne à FCBA : base de données Scopus4.28 – MEASURES ANALYSIS OF ENERGY SAVING RECONSTRUCTION FOR EXISTING BUILDING WINDOWSJuin 2012Les Bâtisseurs d’Emmaüs187
