Entra received the award for a heat pump installation that made the Powerhouse Brattørkaia commercial building in Trondheim possible, Norway, as the first new building to achieve the Powerhouse plus energy standard, i.e. it produces more renewable energy over its service life than all of the energy required to manufacture, operate, renovate and finally dismantle the building and dispose of the building materials at the end of its useful life will . The competition entry: “Heat pump as a key factor for a positive energy building” took first place in the DecarbBuilding category. Skanska, a leading project development and construction group, was the prime contractor for the project.

“I congratulate Entra and Skanska for working on this project. We are proud to have contributed the technology and expertise that helped Entra gain recognition for the important work it is doing in environmentally friendly, energy efficient buildings performs “said Dave Dorney, Vice President and Managing Director, Europe, middle East and Africa, Johnson Controls Industrial Refrigeration. “Today the building and construction industry accounts for around 40 percent of total energy consumption worldwide. By changing the design and focusing on construction methods that transform buildings into renewable energy producers, the Brattørkaia powerhouse is making great strides towards net-zero intelligent buildings. “

The Heat Pump Award has been an initiative of the European Heat Pump Association (EHPA) since 2011, which honors the most energy-efficient, intelligent and sustainable heat pump projects worldwide Europe. This is the second year in a row that a Johnson Controls installation has been recognized by the EHPA.

Powerhouse Brattørkaia is the first new building of its kind in Norway for energy efficiency and green electricity generation. It’s also a breakthrough project in terms of technology with Johnson Controls’ OpenBlue digital solutions. The building is designed to be energy-positive from the ground up and the integrated photovoltaic system on the roof, south facade and upper part of the west facade generates more than 400,000 kWh / year of electricity.

In 2019, Johnson Controls installed a single seawater-derived heat pump with natural refrigerant in the 18,200 m²2, eight story building. The heat pump not only supplies hot water for heating to the powerhouse, but also to the adjacent BI Campus Trondheim Business School. The hot water is first sent to the commercial school for heating and then back to the powerhouse, which uses the remaining heat. Originally, the two buildings were to be built with two heat pumps each as required, but thanks to a clever system design they now achieve outstanding efficiency with just one heat pump.

In combination with many other innovative measures to achieve high performance, this enables the building to produce a significant excess of energy in summer. Much of this excess solar power is delivered to the bus stop and charging station next to the building, where an electric bus drives every 10 minutes to charge during the day.

“Winning the EHPA award is an endorsement of both our commitment to building an energy efficient building with zero energy technology that serves as a leading example for the Northern Hemisphere and our collaboration with Johnson Controls on cutting edge innovation and deep industry expertise in support of environmental protection through energy-efficient buildings, “said Rune Stene, Managing Director of Powerhouse. “The heat pump is the decisive factor in making the building ‘over the top’ and becoming a surplus energy building. This is a verified ‘best practice’ example that has been running successfully for two years and hopefully will inspire others to design similar buildings. “

Controlling energy consumption in heating and cooling buildings is essential if nations are to achieve global CO2 reduction and sustainability goals. Heat pumps play an important role in the decarbonization of buildings and industry.

Johnson Controls has heat pump solutions for more than a dozen district heating and cooling applications in. delivered Denmark, Finland, France, Germany, Italy and Norway.

In addition, through its OpenBlue building sustainability platform, Johnson Controls has helped its customers and future generations use less energy, conserve resources, and find ways to achieve healthy, carbon-free communities – and ultimately an environment for healthy and healthy people to create places and a healthy planet. Johnson Controls’ digital OpenBlue platform and building optimization services can improve energy efficiency and associated CO2 emissions by 50% and more.
