Abstract [en]

The European building stock was renewed at a rapid pace during the period 1950–1975.In many European countries, the building stock from this time needs to be renovated, and thereare opportunities to introduce energy efficiency measures in the renovation process. Informationavailability and increasingly available analysis tools make it possible to assess the impact of policyand regulation. This article describes methods developed for analyzing investments in renovationand energy performance based on building ownership and inhabitant socio-economic informationdeveloped for Swedish authorities, to be used for the Swedish national renovations strategy in2019. This was done by analyzing measured energy usage and renovation investments made duringthe last 30 years, coupled with building specific official information of buildings and resident areacharacteristics, for multi-family dwellings in Gothenburg (N = 6319). The statistical analyses showthat more costly renovations lead to decreasing energy usage for heating, but buildings that havebeen renovated during the last decades have a higher energy usage when accounting for currentheating system, ownership, and resident socio-economic background. It is appropriate to includean affordability aspect in larger renovation projects since economically disadvantaged groups areover-represented in buildings with poorer energy performance.

Abstract [sv]

Byggsektorn står inför ett stort renoveringsbehov. Byggnader från miljonprogramstiden har nått en ålder då många olika byggnadsdelar når sin förväntade livslängd. Detta renoveringsbehov är inte jämnt fördelat bland Sveriges fastighetsägare. Det stora flertalet av de ännu ej renoverade byggnaderna från miljonprogramstiden ägs av fastighetsbolag knutna till SABO, men det finns även många privata fastighetsägare och bostadsrättsföreningar som har ett eftersläpande renoveringsbehov eller som har renoverat men fortfarande har en hög energianvändning och alltså troligtvis inte genomfört nödvändiga energieffektiviseringsåtgärder. Det finns också olika förutsättningar för att göra de investeringar som krävs, vilket beror på företagens soliditet, fastigheternas värde och möjligheten att få lån, utrymme för hyresökning etc. Detta gör att renoveringstakten inte kommer att täcka renoveringsbehovet och att vissa delar av fastighetsbeståndet kommer att vara mer eftersatt.

Abstract [en]

Many studies have highlighted the importance of retrofitting to mitigate the energy use of building stocks. An important step in the development of renovation strategy and energy conservation advising is to gather information of the energy performance of the existing buildings. However, renovation strategies must also consider the socio-economic challenges associated with the cost of energy retrofitting. This paper describes the development of an energy atlas of the multifamily building stock in Sweden for visualizing and analyzing energy use and renovation needs. The atlas has been developed using Extract Transform and Load technology (ETL) to aggregate information on the energy performance, building ownership, renovation status, and socio-economic status of inhabitants from various data sources. The atlas can visualize the energy use and renovation status of multifamily buildings in 2D maps and 3D models, displaying data for either individual buildings or aggregated data on spatial scales ranging from 250 × 250 m squares through district and municipality to county areas. A demonstration of its use on national and city scales indicates that energy retrofits of multifamily buildings reaching a service life of 50 years can reduce the energy use of the existing building stock by up to 50% relative to 1990. However, costs associated with renovation and energy retrofits of multifamily buildings can be problematic, especially in economically weak suburbs. A good understanding of past and future renovation needs and socio-economic consequences is important in the development of a sustainable national renovation strategy. © 2017

Abstract [sv]

Byggsektorn är inne i en period av mycket hög aktivitet. Över 700 000 nya bostäder efterfrågas, samtidigt som miljonprogrammets byggnader börjar nå sin förväntade livslängd. Detta är en enorm utmaning, men det är också en möjlighet, där vi kan nå energi- och klimatmål och skapagoda boendemiljöer till rimlig kostnad.
