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 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...
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...
Urban construction projects are essential in reducing the housing deficit of the latest urbanization trend (UN, 2015 & 2018). As such, construction projects contribute to more attractive, sustainable and economically viable urban areas once they are finished. However, construction work and...
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: Construction sites are among the major sources of greenhouse gas emissions (GHG) in the construction industry. Large quantities of construction materials and other resources need to be transported to, within, and from construction sites. Implementation of different construction...
Current European legislation calls for the abatement of greenhouse gas (GHG) emissions through better building design and technological solutions, in order to reduce operational energy use, embodied energy and embodied material emissions originating from buildings. Presently, environmental...
This second version (V2.0) of the ZEN definition guideline report builds upon version V1.0 of the ZEN definition guideline and series of ZEN definition reports. The ZEN categories for GHG emissions, energy, and power have been updated after having been tested in selected pilots. In addition, a...
Urban areas pay increasing attention to new construction and infrastructure works, mainly due to the rapid global rise in urbanisation. In the long run, these works have a positive correlation with the economic and social attractiveness of cities. Construction strongly relies on logistics activities...
The building and construction sector is responsible for 3.4% of total GHG emissions in Norway. Around 95% of these emissions arise from the combustion of fossil fuels for the operation of construction machinery and transport. This highlights the importance of transitioning to renewable energy...
This third version of the ZEN definition guideline report builds upon version 1.0 and 2.0 of the ZEN definition guideline reports and series of ZEN definition reports. This report gives further details on the ZEN KPI tool and on ZEN KPI reference, limit, and target values. A major change involves...
Off-site construction is considered as environmentally preferable to on-site due to the controlled environment for planning and production before assembly in the construction site. However, evaluating the actual environmental benefits and drawbacks from a life cycle perspective is important to avoid...
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...
The concept of emission free construction sites (EFCS) has emerged as a prioritised measure to reduce greenhouse gas emissions from Norwegian construction activities. EFCS have been evaluated through several pilot projects in Southern Norway, whilst none are found in Northern Norway. This study aims...
Preface. This report is a deliverable (D4.3) in the MIMIC project, under WP4, Task 4.3. The aim of WP4 is: • test the Smart Governance Concept 1.0 developed under the previous CIVIC project with an attempt to include construction logistics planning in city level planning (Task 4.1 Testing of Smart...
Construction site activities are one of the main contributors to GHG emissions in the construction industry. There are several on-going initiatives on finding low and zero emission solutions for reducing GHG emission from construction sites. The objective of this paper is to investigate the emission...
A relevant approach to limit virgin materials consumption and waste in the construction industry is to use reclaimed construction products. Their sustainability performance depends on various parameters, including the activities needed to reuse them. Currently, the life cycle sustainability...
