In Norway, the most common sustainability certification system for buildings is called "BREEAM NOR." BREEAM NOR stands for Building Research Establishment Environmental Assessment Method for Norway. BREEAM NOR is based on the internationally recognized BREEAM system but has been adapted to suit Norwegian building practices, regulations, and environmental conditions. It assesses the environmental performance of buildings across various categories, such as energy, water, materials, waste, pollution, and health and well-being. Similar to other BREEAM schemes, BREEAM NOR provides a framework for evaluating and rating the sustainability of buildings. It aims to promote environmentally friendly and energy-efficient building practices, reduce the environmental impact of buildings, and improve the overall quality of the built environment in Norway. BREEAM NOR assessments are typically conducted by licensed assessors who evaluate buildings against the BREEAM NOR criteria. Buildings can achieve different certification levels based on their performance, ranging from Pass, Good, Very Good, Excellent, and Outstanding. By encouraging sustainable building practices and providing recognition for environmentally responsible projects, BREEAM NOR plays a crucial role in advancing sustainability in the Norwegian construction industry and contributing to national and international sustainability goals.

RATINGS &
CERTIFICATION

14. WHAT ARE THE DIFFERENT BREEAM
RATINGS?
When it comes to the overall performance and rating
to BREEAM for a new construction project, a number
of different factors are considered, these are;
● The BREEAM rating level Benchmarks
● The environmental section weightings
● The Minimum BREEAM standards
● The BREEAM assessment issues and
credits
BREEAM RATING % Score
❖ Outstanding ≥ 85
❖ Excellent ≥ 70
❖ Very Good ≥ 55
❖ Good ≥ 45
❖ Pass ≥ 30
❖ Unclassified <30
BREEAM rating benchmarks enable a client and all other stakeholders to compare the performance of a newly
constructed building with other BREEAM rated buildings, and the typical sustainability performance of a stock
of new non-domestic buildings in the UK. In this respect each BREEAM rating broadly represents performance
equivalent to:
1. Outstanding: Less Than the top 1% of NORWAY new non-domestic buildings(innovator)
2. Excellent: Top 10% of NORWAY new non-domestic buildings(best practice)
3. VeryGood: Top 25% of NORWAY new non-domestic buildings(advanced good practice)
4. Good: Top 50% of NORWAY new non-domestic buildings(intermediate good practice)
5. Pass: Top 75% of NORWAY new non-domestic buildings(standard good practice)
An unclassified BREEAM rating represents performance that is non-compliant with BREEAM, in terms of failing
to meet either the BREEAM minimum standards of performance for key environmental issues or the overall
threshold score required to achieve at least a Pass rating.

24. The waterfront façade is the slimmest face of the building, allowing
the project to be read at a similar scale with its neighbors. Clad with
black aluminum and solar panels, the façade is reflected in the
adjacent Trondheim Fjord.
Location
● The Brattørkaia Power Plant is located next to the port of the city of Trondheim, Norway.
● Located 63º north of the Earth’s equator.
OBJECTIVE
TO STUDY?
It offers the
opportunity to
study and explore
how to generate
and store solar
energy in difficult
conditions since
sunlight in this
region varies
greatly according
to the seasons of
the year.

25. Introduction
● According to the World Resources Institute, the energy sector and the construction industry account for more than 40% of global emissions
and heat retention. As the world population and the severity of the climate crisis continue to grow, there is the challenge of thinking about how
to build responsibly, creating high quality spaces for people and at the same time reducing the environmental footprint.
● The Powerhouse Brattørkaia, as the world’s most energy efficient building in the world, aims to set a new standard for the construction of
tomorrow’s buildings: that they produce more energy than they consume during their useful life, including construction and demolition. This also
includes the energy incorporated into the materials used to build the building.
Concept
● Powerhouse Brattørkaia aims to establish a new standard for the construction of tomorrow’s buildings, one that produces more energy than it consumes
during its useful life, including construction and demolition.
● One of the pre-construction steps was the ideal choice of the site, a place that would guarantee maximum sun exposure during each of the seasons. Once
the challenge was found, it was to find the best architectural way to use and store this energy. With this concept and a triple objective: to maximize the
amount of clean energy produced by the building, minimize the energy required to execute it and serve as a pleasant space for its tenants and the general
public, the Snøhetta studio designed a building whose sloping roof and Pentagonal, together with the upper part of the façade, is lined with 2,867 m2 of
solar panels, strategically located to take advantage of as much solar energy as possible.
● This surface of solar panels produces a clean and renewable energy of 458,457 kWh per year making the building work as a small generating plant located
in the center of the city.
Powerhouse Brattørkaia

26. Spaces
● The building with 17,800m2, 13,500 m2 on the ground level divided into
8 floors and one mezzanine, has on the facade that looks at the sea the
narrowest face to show a scale similar to that of its neighbors. It also has
a mezzanine and underground parking.
● Inside, a large atrium that functions as a public garden is surrounded by
horizontal crystals that allow natural light to enter the bar on the ground
floor and the visitor center open to the citizens of Trondheim as an
educational resource for school groups and the general public.
● In turn, it allows natural light to enter the work spaces that open to this
atrium on each level. The visitor center explains Powerhouse’s energy
concept and supports public knowledge and discourse on sustainable
construction strategies for the future.
● In the building’s footprint a large space has been incorporated for the
storage of the energy it produces, allowing the storage of the obtained
during the summer, in which the daylight is almost total, 20 hours, to be
able to use it in the winter months when this is minimum, 5 hours.

FEATURES

29. Structure
● The structural system of the building
consists of a low-emission concrete
thermal mass that is exposed through
strategic roof cuts. The mass absorbs and
retains heat and cold and helps regulate
the temperature in the building without
using electricity.
● A massive “skylight” incorporated in its
polygonal roof with a steep slope, allows
sunlight to seep through the central
atrium. The roof is inclined to optimize the
maximum energy harvest and covered
with more than 2800m2 of black solar
panels that absorb as much energy as
they can during long summer days and
store it for winter. Within this illuminated core is an atrium that
functions as a public garden with horizontal glass
windows on the sides, providing skylight into the
below canteen.
This skewed lightwell allows daylight to enter the
building on every floor, and gives the people working
inside a great view of the city.
On average, Powerhouse Brattørkaia produces
more than twice as much electricity as it
consumes daily, and will supply renewable
energy to itself, its neighboring buildings,
electric buses, cars and boats through a local
microgrid.

30. Materials
● In its construction mainly low emission concrete,
steel, crystals and solar panels were used.
● Taking advantage of certain technologies such as
building insulation for maximum efficiency, installing
intelligent solutions for air flow so as to reduce the
need for heating, heat recovery solutions to ventilate
air and gray water (except for those coming from
toilets ), using seawater for heating and cooling and
implementing low consumption appliances, the
building is extremely energy efficient.
1. The Powerhouse strategies that balance its focus on fresh air and
thermal comfort with extreme energy-efficiency.
2. The ventilation system provides pleasant and clean air to the indoor
spaces.
3. The office landscape contains technical installations for air supply that
regulate ventilation.
4. The air is let out close to the floor at low speed, while the extraction
takes place centrally by suppression in the stair shafts. Further, the
building’s structural system consists of thermal mass – low-emission
concrete – which is exposed through strategic cutouts in the ceiling.
Ventilation and Heating Technologies

31. In order to reduce energy use on lighting, the
building employs a concept called “liquid
light”, which allows the artificial light to
smoothly dim up and down according to the
activity and movement in the building.
Taken together, these strategies allow
Powerhouse Brattørkaia to consume only
about half the amount of energy for lighting
than a typical commercial office building of
comparable size would.

32. Solar panels
● For solar panels to produce more
energy they must be at an angle of
90º towards the sun. As we
approach the equator this angle will
be more flat and if it is towards the
more inclined poles.
● With respect to the existing surface
under the roof, the more square
meters more surface covered with
solar panels is needed to meet the
needs of the building.
● For this reason in a skyscraper it is
very difficult for the installation of
solar panels to produce enough
solar energy for the entire building,
unless they are also placed on its
facade.
photovoltaic panels are key to repaying the
carbon debt created by constructing a
building

33. How does the building work?
● The south-facing building is equipped with almost 3,000 square meters of solar panels that
have converted the pentagonal-roof into a large area enabling the building to become an
energy-host. It's said to be capable of generating around 485,000 kWh per year and
consume 4.9 kWh/m2.
● The building's electricity can be generated by solar cells, heat exchangers and heat pumps.
Likewise, the sea, which is another natural resource, is used to heat and cool the building.
● The location of solar cells and windows are positioned to achieve maximum sun intensity in
order to optimize daylight conditions and reduce energy consumption.
● For instance, in the areas most exposed to the sun, the buildings internal solar-heating will
be turned off, until the building is longer exposed, whereby the solar-heating will be
resumed.
● The floors and offices of the building are designed to efficiently circulate hot and cold air, and
special concrete is used to help regulate the temperature.
● In order to reduce energy consumption on lighting, as another example, the building has
adopted a concept called "liquid light," which allows lighting to be dimmed up and down
according to people's activity and movement within the building's rooms, which is powered
by an artificial intelligence system.
● Sitting 63-degrees north of the Earth's equator, where the amount of sunlight significantly
varies by seasons, Powerhouse Brattørkaia stands for a unique opportunity to explore how
to harvest and store solar energy under challenging weather conditions.
● “Energy-positive buildings are the buildings of the future. The mantra of the design industry
should not be ‘form follows function’ but 'form follows environment' .
● This means that the design thinking of today should focus on environmental considerations
and reducing our footprint first, and have the design follow the premise," said Snøhetta
founder Kjetil Trædal Thorsen of design and architecture firm Snøhetta to Smart Cities
World.
Building as an
energy distributor
● The car can purchase
electricity from the
Powerhouse Brattørkaia
building using the digital wallet,
and therefore be certified as a
green energy vehicle.
● Car owners have several
opportunities to earn points
(digital money) while driving,
for spotting and reporting
potholes on the road to an
urban agency.
● Powerhouse Brattørkaia is
developed by Norwegian
property developer Entra,
construction company
Skanska, environmental
organization ZERO,
architecture firm Snøhetta and
consulting company Asplan
Viak.

34. ● Today, the Powerhouse
Brattørkaia is
energy-positive across
the entire building life
cycle, including
embodied energy in
construction materials
and end-of-life
deconstruction.
● Therefore, it is producing
more electricity than it
consumes daily,
supplying renewable
energy to itself,
neighboring buildings
and vehicles via a local
microgrid.
Certified quality Major achievements
1. Solar photovoltaic array produces
485,000 kWh annually, which is
enough excess electricity to charge
200 electric vehicles.
2. Seawater-sourced natural refrigerant
heat pump provides complete
cooling and heating for the office and
some neighboring buildings through
a district energy system.
3. Utilization of air-side heat recovery, a
super-insulated envelope, control of
thermal mass for heating and
cooling, and occupant-adaptive
lighting and ventilation systems
further enhance energy efficiencies.
4. Its high efficiency has earned it the
BREEAM Outstanding certification
for green building standards.
● These diverse global projects
demonstrate that focusing on
decarbonization,
electrification, efficiency and
digitization can deliver
net-zero buildings and
communities that are smart,
safe, sustainable and
affordable.
● At this critical juncture in the
climate crisis, fully
decarbonizing the world’s
buildings by 2050 is vital to
meet the Paris Agreement
Goals.
