Energy harvesting electronic locks used for sustainable construction project in Denmark

Esbjerg’s new “A Place To” housing complex focuses on sustainability, with the aim to maintain a green profile through its life-cycle by using energy harvesting locking with cloud management to secure the site.

Over 300 apartments are divided between three towers at A Place To housing complex in Denmark. These connect with common areas which offer multiple opportunities for social activity and “co-living”. There’s a cafe, fitness and yoga, a big screen, reading nooks and workstations, communal kitchens and more.

The developer is a Premium Member of Green Building Council Denmark — an organisation which promotes sustainable construction — and sought efficient access control in keeping with A Place To’s contemporary style and sustainable ethos.

The developers looked for an energy-saving solution which would operate without batteries or wires but also be able to benefit from cloud-based access management to give staff convenient, 24/7 control from anywhere.

Integration-readiness was another priority, to provide seamless operation with other building technologies, including online readers and door-phones, and inbuilt future-proofing, adding new features or capacity anytime.

Energy harvesting locking with cloud management

PULSE key-operated electronic cylinders from ASSA ABLOY Opening Solutions with energy-harvesting technology was chosen to secure the apartments: “We went for a future-proof solution which was maintenance-free and where we did not have to change batteries,” explains Peter Høpfner, COO and Founder of A Place To.

The devices are designed to be self-powered and run without any external energy source. The power generated on key insertion is harvested to energise encrypted electronic security. “It was a big plus with PULSE that keys and locks are battery and cable free,” he adds.

Access control at the site is managed in the cloud with Incedo Open software, which is designed so that the administrator can change anyone’s access permissions online; keys are quickly updated at integrated door-phones or online readers so that resident authorisations are always current.

This software is also designed to disable lost keys quickly, plus an administrator can see who has used a lock at any time, which helps to foster a sense of security among residents. The PULSE key is reported to contain an RFID chip, doubling as an access card for the entrance and communal areas, for convenience and efficiency.

The platform-based Incedo ecosystem is  “future-proof, so there is the possibility of future integrations with other systems” says Høpfner. When new needs arise at A Place To, the system can grow and adapt on demand.

Building Energy Award winner

In May, PULSE was awarded winner of the Building Energy Award 2022, organised by BYGGERI, Denmark’s largest construction fair. This award is given to energy-saving building parts and components for the construction sector.

The awards purpose is to celebrate innovative products and solutions within construction and to increase knowledge of climate-friendly building materials.
