Page 1 of 30A c c e p t e d M a n u s c r i p t The building sector is well known to be one of the key energy consumers worldwide. The renovation of existing buildings provides excellent opportunities for an effective reduction of energy consumption and greenhouse gas emissions but it is essential to identify the optimal strategies. In this paper a multi-criteria methodology is proposed for the comparative analysis of retrofitting solutions. A c c e p t e d M a n u s c r i p t far from being optimal solutions. The required additional investment, which is needed to obtain an overall performance improvement of the envelope compared with the common practice to date, is relatively low (8%) considering the obtained life cycle environmental and financial savings (43% and 45% respectively).

Laburpena: «Birgaitze energetikoak gizarte-etxebizitzan: portaera termikoaren analisia» doktorego-tesia eraikinen birgaikuntza energetikoaren ebaluazioan datza, eta prozedura honek barne hartzen dituen atal ezberdinak kontuan hartzen ditu: datu-eskuratzea eta monitorizazioa, datuen tratamendua eta lortutako emaitzen analisiak, esaterako. Helburu horrekin, atal esperimentalean bi monitorizazio ezberdin barne hartzen ditu. Lehenik, hamar gizarte-etxebizitzen landa-azterketa bat aurkezten da hirugarren kapituluan; laugarren kapituluan etxebizitza adierazgarri baten monitorizazio zehatz baten deskripzioan arreta jartzen du. Estazio klimatiko bat kokatzeaz gain, etxebizitzaren monitorizazioa eginahal izateko hirurogei tenperatura-sentsore baino gehiago erabili izan dira. Monitorizazioa egin ondoren, atal esperimentalean lortutako datuen tratamendua garatzen da bi simulazio ereduren bidez. Azkenik, tesi honen azken atalak simulazioaren diseinuan eta aipatutako simulazioen bidez lortutako emaitzen ebaluazioan arreta jartzen du.

“…The results of their study suggested that building lifespan does not contribute to the optimum measures variation as much as the economic parameters. A brief review of several studies [16,20,21,23,25,27,28,31,[33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] is compiled and presented in Table 1, where the methodology, approach, some assumptions and the applicability of the studies can be compared. …”

The Implications of Climate Zones on the Cost-Optimal Level and Cost-Effectiveness of Building Envelope Energy Renovation and Space Heat Demand Reduction

Abstract:The cost-optimal level of energy performance for buildings shall be identified according to the European directive of 2010. The Swedish building stock needs comprehensive knowledge and an overall strategy for the cost-optimal level of renovation. This paper studies the contribution of Swedish climate zones to the cost-optimal level of renovation on a multi-story residential building in Sweden from the building owner perspective. The building space heat demand is simulated for four Swedish climate zones. The net present profit (NPP) method is defined and used in this study in order to analyze the cost-optimal level and the cost-effective renovation of building envelope components (e.g., attic floor, basement walls, exterior walls and windows). The implication of different discount rates is studied, as well. The results show that the optimum renovation of the building envelope offers 51% more energy savings for space heating when the building is in a northern climate zone compared to a southern zone. The study suggests that different renovation strategies for the building stock renovation need to be identified, separately, for each climate zone. The NPP analysis identifies the minimum required investment and maximum achievable energy savings that are needed to have a cost-effective renovation. The broad range of studied climate zones provides the opportunity to apply the obtained results to other climate zones by either interpolation or extrapolation of NPPs for the buildings with similar characteristics.
