The garage feels much safer

When Landskronahem needed to update the lighting in its garages, the switch to LED luminaires from Exaktor was a real bonus that reduced energy consumption by as much as 71 per cent. Sensor control cut consumption by a further 22 per cent.

The gradual phasing out of 17 million old fluorescent tubes in Sweden as part of the adaptation to new EU directives makes a direct difference to energy consumption where new LED luminaires take over. And cheaper electricity bills are not the only benefit.

– We have received great feedback from our tenants who feel that the garage is much safer,’ says Daniel Nordstedt.

Attendance management makes a big difference

Daniel is an IT and technology coordinator at Landskronahem and is a member of the company’s energy group where, like many others in these times, they have been struggling with soaring energy prices.

“We looked at how we could save and streamline our energy use and gradually got into this with lighting, especially in our garages,” says Daniel.

The housing company Landskronahem has seven garages adjacent to its properties and when they did an inventory on the lighting side, they quickly realised that there were major shortcomings, especially in the control system.

– We realised that presence control with sensors could make a difference, so we contacted Ahlsell for advice on choosing new luminaires,’ says Daniel.

Programming for lighting optimisation

As the leading technical distributor of installation products in the Nordic region, Ahlsell has a central department with specialist lighting salespeople. The lighting specialists carry out project planning at the customer’s premises and suggest suitable products that result in many customised and energy-saving solutions at the customer’s premises. The proposal that landed at Landskronahem was Exaktor luminaires from Proton Lighting.

Hans Malmros, regional KAM at Ahlsell, explains:

– ‘It has been a lot of Exaktor for us because it suits many of our customers’ purposes. In addition, we have received very good help from Rickard Bengtsson, who has become a bit of an extended arm for us.

Yes, Rickard Bengtsson, district salesman for Proton Lighting in the southern district, has definitely had a hand in it. In all the garages where the Exaktor luminaires have been installed, Rickard has assisted with programming for lighting optimisation. And Rickard has been in close contact with Daniel to go through all the technical solutions.

“Daniel is a bit of a technology geek and is extremely easy to learn,” says Rickard.

Upgraded to the latest system

It’s true that Daniel likes technology. The last garage where it was installed was able to use the very latest LED luminaires from Exaktor, upgraded with the Koolmesh system. Here Daniel gives an extra plus to the new control.

– ‘It’s so easy to programme. The whole system is very easy to keep track of and I have received good support from Rickard on how to manage the system after commissioning. I like that you can so easily see the energy consumption and adjust the lighting,’ says Daniel. The new, upgraded Koolmesh system has many advantages, says Rickard.

– Bluetooth 4.0 gives you a shorter range between luminaires and the system provides easy access to remote control of the installation. It’s simply much better. Daniel continues: I find the new system to be both more stable and faster at managing all the luminaires in the network.’

Before the installation, we were averaging around 49 kWh per day. With the new sensor-controlled LED luminaires, we’ve got down to as low as 4.2 kWh per day.

From 49 to 4.2 kWh per day

The last installation was so recent that at the time of writing you can’t see many statistics. But when Daniel goes into the system and looks at the hourly energy consumption for individual days, the figures speak for themselves.

– ‘Before the installation, we were averaging around 49 kWh per day. With the new sensor-controlled LED luminaires, we’ve got down to as low as 4.2 kWh per day,’ says Daniel.
The garage is divided into 12 zones where the lighting is adjusted based on movement and presence.

– ‘What immediately strikes you when you enter the garage is the new, improved lighting,’ says Hans. Hans and Rickard have seen similar improvements when collaborating on projects and installing LED lighting in schools, sports centres and other public spaces. For example, the classroom lighting at Sundsgymnasiet in Vellinge has been a great success, going from, at worst, 58 Lux with old fluorescent tubes to the current 1000 Lux with LED lighting from Exaktor.

– The right light has many psychological factors that not everyone is aware of. It’s great to hear how enthusiastic both teachers and students are,’ says Rickard.
