Residents complain about noise and pollution from building sites. Construction companies complain about the expense of sitting idle at night and at weekends when regulations are in place. By finding better methods we will help to improve life for everyone in the neighbourhoods and allow construction companies to make better use of the site, identifying low-impact methods and processes that can be performed at any time.
At AirScape, we are proud and excited to be a part of this lighthouse project. Our sensor network provides real-time monitoring of air quality and noise, on and around the construction site.
By measuring and documenting everything, there’s transparency for the company and for residents. It’s a win-win!
Project – The Green Construction Site of the Future
Project start: January 2021
Expected completion: December 2023
2030 climate targets and a large focus on pollution from construction sites near cities make it necessary to look at a green transition in the construction industry. Until December 2023, Per Aarsleff and the project Green Building Site of the Future will examine the effect of various measures on one or more selected construction sites.
The project establishes a data-driven, full-scale demonstration of the green building site of the future. The initiatives involve converting construction machines to electricity and other alternative fuels such as HVO or GTL. Some special machines that cannot be converted will have a particulate filter and SCR catalyst fitted. In addition, CO2-reducing energy systems will be established. For example, solar cells and digital tools will contribute to on-site logistics optimization and smart behaviour.
Sensors measure the effect
Sensors on the site, and on the individual vehicles, will measure the effect of the actions, which will be implemented individually. With the help of sensor technology and location data, among other things, a heat map shows where, for example, a tractor has run, what it does and how much it costs in terms of emissions of particles and CO2. The goal is to create a so-called digital twin that documents current driving, and where it is possible to see how logistics can reduce driving and thus emissions and CO2.
Solar cells and heat pumps are integrated
A further initiative is a smart energy infrastructure with solar cells and heat pumps on the scavenger trucks, supplemented by energy storage for balancing the load. The Danish Technological Institute will uncover and analyse electricity consumption to identify possible energy savings and increased flexibility.
Evidence for green initiatives
The purpose is to provide the industry with evidence of which green initiatives provide the most climate and environmental impact for the money. The vision is that the project will contribute to the sustainable society of the future, where the availability of sustainable alternatives causes more builders to demand more sustainable building sites.

The project is supported by the Danish Environmental Protection Agency’s MUDP program and is a so-called lighthouse project and is carried out in close cooperation with the client, Ejendomsselskabet Olav de Linde A/S.
