The objective of this report is to provide a state-of-the-art review on relevant existing studies that could be used as a background for tool development and guidelines in the EE settlement project. The report investigates how different dwelling types and settlement patterns affect travel behaviour...

Forord. Dette notatet er første versjon til et merkeordningssystem for avfallsreduksjon på byggeplass og presenterer resultater fra forskningsprosjektet ConZerW (Construction Site Zero Waste). Målet med notatet er å tydelig definere systemgrensene for avfallsregnskapet for å sikre en korrekt...

Given that most of the world’s building stock for the next 30 years already exists today, renovation of existing buildings and infrastructure represent an important pathway towards a more sustainable future. The aim of this paper was twofold: 1) to evaluate potentials for waste reduction, efficient...

Accelerated climate aging experiments and cup measurements have been performed to investigate the effect of adding TiO₂ nanoparticles and nanoclay to acrylic stain coatings against the influence of weathering. The coated specimens resistance toward solar radiation and water spray was evaluated by...

This work examines the effect of wood specimens coated with water based acrylic coatings modified with TiO₂ and clay nanoparticles against weathering strain. The long-term durability of the specimens towards climate strain was studied within a relatively short time frame by accelerated climate...

Building renovation is a key measure to reduce energy consumption and Greenhouse gas (GHG) emissions, and ease the transition to a fully renewable energy system. This paper applies the IEA EBC Annex 75 methodology for investigating the cost optimal and environmental trade-off between investment in...

This document outlines the definition, key performance indicators (KPI) and assessment criteria for the Research Centre on Zero Emission Neighbourhoods in Smart Cities (ZEN research centre). This first version of the ZEN definition includes contributions from the ZEN partners. In total, around...

Various schemes are established to evaluate the sustainability of buildings during their life cycle. These schemes introduce a range of evaluation criteria and indicators and are periodically revised to align with current sustainability trends. This study reviews leading schemes in Norway, and...

SINTEF has carried out an analysis of emission reduction measures from the construction site activities for the renovation project Storgata nord in Tromsø. This involves a mapping of possible measures that can contribute to greenhouse gas emission (GHG) reduction in the construction phase for the...

This work summarizes the output of durability, reaction to fire properties, and environmental impact of wooden claddings subjected to treatments modified with TiO₂ and clay nanoparticles. The objective was to investigate the effects of 1 wt% of TiO₂ and clay nanoparticles in existing water-based and...

Denne rapporten beskriver definisjonen, nøkkelindikatorer og vurderingskriterier som benyttes i forskningssenteret for nullutslippsområde i smarte byer (ZEN-senteret). Denne andre utgaven av ZENdefinisjonen bygger på versjon v.1.0 av ZEN-definisjonen (1). ZEN-kategoriene klimagassutslipp, energi og...

In the building sector, various adhesive materials are experiencing an increased usage for sealing of overlaps and joints between most commonly used building materials, around penetrations, pipes and windows for increasing the moisture tightness and the airtightness of buildings. Among the adhesive...

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...

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...

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...
