Construction industry is one of the main contributors to the world's emissions and material footprints. Reuse of construction products is one way to lower the sector's embodied emissions and increase resource utilisation. The aim of this study is to identify the main drivers and challenges affecting...

Introduction. The ongoing urbanization trend makes local governments densify their built environment, hence stimulating construction and renovation works in urban areas. Construction intrinsically strongly relies on logistics activities, which in turn are the source of environmental nuisances. The...

...databases, and tools, one focused on travel behaviour and housing preferences (Landa-Mata et al 2018), and one on district-level tools and databases (Fufa et al 2019), were performed to fill in the gaps in the current approach and bring new insights to the project. The findings from literature review...

Present day European legislation focuses upon the reduction of greenhouse gas (GHG) emissions in buildings through better design and technological solutions, with a view to reduce operational energy use and embodied GHG emissions. Currently, environmental performance assessment tools for buildings...

For å kunne kvantifisere utviklingen av et nullutslippsområde er klimagassutslipp fra materialer og energibruk i drift viktige indikatorer. Det er utviklet en standard for metode for klimagassberegninger for bygninger – NS 3720:2018 som benyttes for å kvantifisere klimagassutslippene gjennom hele...

This report presents the results from a sensitivity analysis regarding the influence of using emission data from Norwegian EPD’s instead of the generic data from Ecoinvent, using different CO2eq-factors (for electricity in the operational phase) and electricity load from household appliances on the...

Denne rapporten er et resultat av at SINTEF Byggforsk og NIKU ble tildelt midler fra Riksantikvarens FoU-midler til å gjennomføre prosjektet MIL-ORG – Miljøvennlig Oppgradering og Rehabilitering av Gamle og verneverdige bygninger. MIL-ORG-prosjektet har tatt utgangspunkt i hvordan verneverdig...

The Visund office building is a pilot project with in the Research Centre on Zero Emission Buildings (ZEB) in Norway. The building has 2031 m 2 of heated floor area and is located at Haakonsvern, about 15 km from the centre of Bergen, Norway. The building is owned by the Norwegian Defence Estates...

Powerhouse Kjørbo, located in Sandvika near Oslo, consists of two office blocks from the 1980´s that have been upgraded to energy-efficient and modern offices. The Powerhouse goal is that the refurbished buildings over their lifetime generate more energy than they consumes. This implies that the...

Forprosjektet om utslippsfrie byggeplasser har hovedfokus på fagfeltene samferdsel og transport og skal bidra til at Oslo kommune kan stille bedre krav til utslippsfrie byggeplasser gjennom innovative offentlige anskaffelser ved å benytte resultater og metodikk fra FoU. Forprosjektet omfatter arbeid...

REBUS project vision and objectives: The research project REBUS – REuse of Building materials – a USer perspective started in 2020 with a vision of developing a knowledge platform to enable the wider and more efficient implementation of reusable building materials. REBUS aimed to address the main...

Denne rapporten er utarbeidet på oppdrag for Riksantikvaren og har som mål å gi et helhetlig bilde av den miljømessige betydningen av gjenbruk av eksisterende bygninger. Den anvendte metoden innebærer en systematisk kartlegging og metaanalyse av livssyklusanalyser ved reha-bilitering og oppgradering...

This report summarises the life cycle assessment methodology used to calculate the GHG emissions from a case study considered under "Utslippsfrie byggeplasser forprosjekt". The greenhouse gas emissions (GHG emissions) of Lia barnehage were calculated based on the Life Cycle Assessment (LCA...

This report has been commissioned by the Norwegian Directorate for Cultural Heritage with the aim of providing an overall picture of the environmental significance of the reuse of existing buildings. The approach used has involved a systematic assessment and meta-analysis of life cycle assessments...
