Lampemagasinet, the family business with 16 stores across the country, has received a green boost at its head office. Eiendomsspar has installed solar cells on the roof of Vollaveien 20 A and B, provided by Sunday Power, which leads Eiendomsspar's venture into solar energy. This initiative allows Lampemagasinet and the other tenants of the commercial building at Alnabru in Oslo to now use short-term, renewable energy.

“We are very pleased that Eiendomsspar has chosen to install solar cells on the building of our head office,” says Frode Eng, CEO of Lampemagasinet.

“Being able to use local, renewable solar energy is a good fit for our company. Sustainability is important and we look forward to many sunny days in the years to come.”

Tenants offered solar power

In addition to Lampemagasinet's head office, there are a number of other tenants in Vollaveien 20 A and B. Among them are Megaflis and NRK, which have costume warehouses here.

The installed power at the plant is of 517 kWp, and will provide an estimated annual production of 405,000 kWh. This corresponds to the annual electricity consumption of 27 households, and will provide an annual climate saving of approximately 53,000 kg CO2*.

Unique mounting system for pitched roofs

The peculiarity of this installation is that the building has both a flat roof and a pitched roof.

“This meant that we have used different installation methods on the different parts of the roof. We have done this to make the best use of the roof so that we can maximize value creation. On the flat roof, the panels are ballast mounted. This means that the plant is set loosely on the roof, and held in place by its own weight and ballast in the form of concrete bricks. This method can not be used on pitched roofs. In this installation, a so-called Aeroflat system from IBC is used. This is a unique assembly system that is held in place using weight and friction,” says Kjetil Laupsa Steine, Head of Deployment at Sunday Power.

The installation method used on the pitched roof is Aeroflat system from IBC. The panels are held in place using weight and friction.

Close collaboration between Eiendomsspar and Sunday Power

Eiendomspar has set itself the goal of being a leader in sustainable solutions to meet the current and future needs of their tenants.

” Solar energy is an important contribution to Eiendomspar's work with environmental responsibility. We have collaborated with Sunday Power on a number of installations, and in 2024 five of them will be completed,” says André Dalene, Environment Manager at Eiendomsspar.

The goal is to create more sustainable buildings, but also to maximize the value from the building - both for the building owner and the tenant. The solar cells are also a contribution to meet upcoming stricter requirements for sustainable buildings.

Rikard af Ekenstam, CCO of Sunday Power, looks forward to continuing the good cooperation:

“Real estate couples are leading the way as a good example of how building owners should take responsibility and offer sustainable solutions to their tenants. We look forward to continuing to deliver solutions that support their sustainability goals.”
