Leading consulting group with a 360° approach
A new EU-backed Smart City urban development project entitled READY (resource efficient cities implementing advanced smart city solutions) will in the next five years put new as well as known energy-efficient technologies to the test in homes in Aarhus, Denmark, and in Växjö, Sweden.
The project is to be seen as a demonstration project, says Project Manager Reto Michael Hummelshøj, where the cases in Aarhus and Växjö make up an out-set for a large-scale city transformation, which in turn will be used as an out-set for future urban development processes in cities all over the world.
"The project aims at achieving optimum interaction between, on one side, buildings and local, renewable energy systems and, on the other side, the overall power and heating supply systems," says Hummelshøj.
"We'll adjust consumption to match energy generation by storing locally generated power in used batteries, e.g., from electric cars. Rather than scrapping batteries that are no longer useful for transport purposes, we want to show how they can be used in stationary facilities where reduced battery capacity isn't an issue. In this way, residents are able to primarily draw on locally stored energy when the public utilities experience peaks – allowing the systems to be used in the optimum manner."
By joining forces with leading industrial companies (including Danfoss, RaCell, IKEA, Kamstrup, and local energy supply companies, universities and housing companies), unique solutions will be developed, tested and integrated into the business concept of the companies.
The project will test a palette of technologies in practice, ranging from smart solutions for low-temperature district heating and local storage, over new components such as PVT solar panels that generate power as well as heat, to ICT systems that send out command signals, which allow the project to test the flexible energy systems. The homes will also be fitted with new kitchen solutions that optimise power and water consumption and waste sorting.
"It'll be interesting to see all these solutions on a large scale, interacting, and not least get the residents' verdict after they've used them in their daily lives. With this project, we hope to show how the existing building stock may be renovated profitably to achieve a high standard in terms of energy efficiency," says Hummelshøj.

Financing: The Danish main actors include the City of Aarhus, AVA, Aarhus University, the Ringgården housing association, IKEA, Danfoss, Racell, Lithium Balance, Dong, E.ON and Kamstrup – COWI provides project management. In addition to DKK 143 million allocated by the EU Smart City initiative, which aims to develop and demonstrate future smart city technologies in practice, the project is financed as a public-private partnership (PPP) between 24 companies.
