Ombruk av bygningsdeler kan bidra til lavere utslipp og mindre avfall fra byggenæringen. I denne artikkelen beskriver vi hva vi kan lære fra seks forbildeprosjekter i Norge, Danmark og Belgia. Rammevilkårene for ombruk varierer mellom landene, og vi vurderer prosjektene med hensyn på 1) type ombruk...

Materials production dominates the total Greenhouse gas (GHG) emissions in the construction industry. On the other hand, most existing building stocks are expected to last for the next 30 years, which can contribute to increasing resource efficiency, reducing environmental impact, and creating...

The building and construction industry is responsible for up to 25% of the total waste generated globally. Most construction sites in Norway on average generate 40–60 kg waste per gross floor area built and the average material recovery rate is ca. 46%. Existing requirements focus on waste sorting...

Launched in 2021, the EU Level(s) calculation method for Global Warming Potential (GWP) of buildings could get increasing attention and complement the standards that are currently used in Europe and Norway, EN 15978 and NS 3720. To understand the possibility and consequences of using Level(s) in...

Dette forprosjektet har fokus på delingsøkonomi og er basert på et ideverksted som ble arrangert av Prosjekt Norge. Forprosjektet redegjør for relevante definisjoner innen delingsøkonomiske forretningsmodeller, og peker på sirkulære tiltak i bygg- og anleggsnæringen og potensialet for norske...

Denne rapporten er en av hovedleveransene i prosjektet EE Settlement – Embodied Energy, Costs and Traffic in Different Settlement Patterns. Formålet med rapporten er å gi veiledning og anbefalinger som skal hjelpe myndigheter og fagfolk i arbeidet for en mer bærekraftig by- og regionutvikling...

Sammenlikning av åtte isolasjonsmaterialer med hensyn til energibruk, klimagassutslipp og -innhold og utslipp av helse- og miljøfarlige stoffer. Studien inkluderer utslipp fra råvarer, produksjon og transport til byggeplass i Norge. Rapporten kan brukes som beslutningsstøtte ved valg av...

The objective of this report is to provide a state-of-the art review on relevant existing studies and tools that could be serve as inspiration for tool development and guidelines in the EE Settlement project. The report summarizes the methodological choices and the outcome of two Austrian projects...

Over the last couple of years, research related to fossil free and emission free construction sites has developed rapidly in Norway, with an ambition to contribute towards global, national and regional emission reduction targets. Major public players are already demanding fossil free construction...

Reuse of construction materials and products has great potential to reduce the environmental footprint of a building. However, the way buildings are designed and constructed rarely considers closed loop materials systems and the implementation of reuse in building projects is associated with many...

The weathering performance of Norway spruce coated with acrylic water based paint mixed with TiO₂ and clay nanoparticles were investigated. Uncoated specimens and specimens coated with unmodified paint were used as references. This work describes the effect of the nanoparticles in general and...

The construction industry is one of the world's largest consumers of energy (ca. 40%) and natural resources (ca. 40%). Norwegian statistical data shows that waste from construction, rehabilitation and demolition is steadily increasing. Norway alone generated approximately 1.9 million tonnes of waste...

This work was an investigation of the effect of nanoparticles on the durability of wood specimens exposed to artificial weathering. TiO₂ and clay nanoparticles were mixed with preservative (Wolmanit CX-8) for improving the durability of Norway spruce (Picea abies). Impregnated and untreated...

Introduction. The purpose of MIMIC is to demonstrate how Smart Governance concepts can be used as an aid in the construction and city planning processes to facilitate and support logistics to, from and on urban construction sites to improve mobility and reduce congestion within cities and thereby...

New materials represent an important part of the strategy towards reduced emissions in the building industry. The relative importance of the embodied energy and carbon footprint from the material production in building life cycle assessment is a topic of growing interest. However, there is a...

The Norwegian construction industry is responsible for approximately 1.2% of national GHG emissions during the construction phase. Consequently, there is a growing interest in addressing construction emissions. Therefore, this article aims to comprehensively document and analyse construction phase...

In line with the Paris Agreement, Norway aims for an up to 55% reduction in greenhouse gas (GHG) emissions by 2030 compared to 1990 levels and to be a low-emission society by 2050. Given that 85–90% of today’s buildings are expected to still be in use in 2050, refurbishment and adaptive reuse of...
