Breidablikk Gården: A Norwegian Marvel of Energy-Generating Facade Design
The Breidablikk Gården office building in Haugesund, Norway, represents a pioneering example of how solar technology can be seamlessly woven into architectural design. Moving beyond conventional rooftop installations, this structure, a collaborative effort between Asplan Viak and SolarLab, showcases a facade where photovoltaic panels are not merely additions but fundamental components influencing the building's form, energy generation, and environmental performance. This innovative approach to integrating solar solutions sets a new standard for sustainable construction, demonstrating how aesthetics and functionality can converge to create truly eco-conscious urban developments.
Traditionally, solar panels are often viewed as separate energy-generating equipment appended to a building. However, the Breidablikk Gården project challenges this perception by integrating photovoltaics directly into the building's envelope. This strategic placement allows the panels to serve multiple architectural functions, such as providing shading and controlling sunlight, alongside their primary role of producing electricity. This design philosophy emphasizes that the orientation, position, and overall integration of solar elements should be considered an intrinsic part of the architectural design process, rather than an afterthought. The building's east and west facades, in particular, feature ingeniously angled panels that pivot towards the south, maximizing energy capture while simultaneously creating essential shading for the interior office spaces.
The climate in Haugesund, located in southwestern Norway, presents specific challenges and opportunities for solar energy due to its low sun angles during winter months. To address this, the design team at Breidablikk Gården opted for a facade where panels are angled to optimize solar production, forming a repeated zigzag pattern that extends up to 30 cm inward and outward at each window. This unique geometry not only directs the photovoltaic surfaces towards the sun but also generates shade for the windows, effectively reducing solar heat gain and the need for excessive cooling. This dual functionality highlights the meticulous planning involved in coordinating the photovoltaic system with the building's energy strategy, local climate, and urban context. The result is a facade that is both visually striking and highly efficient, contributing to a substantial annual electricity generation of approximately 100,000 kWh.
Beyond its innovative facade, Breidablikk Gården incorporates a range of sustainable building practices. It combines roof-mounted photovoltaics with the integrated facade system and efficient building services, collectively achieving a BREEAM-NOR Excellent rating. The construction also utilizes low-carbon wood with prefabricated wall modules, where the solar rainscreen acts as an external layer, protecting the primary structure while being part of a larger, integrated envelope assembly. Furthermore, the facade features an iridescent coating that changes appearance based on light and viewing angles, adding a dynamic aesthetic element that enhances the building's presence within the city. This project exemplifies a forward-thinking design process, facilitated by SolarLab's method of simulating potential electricity production using 3D models and local climate data, allowing for informed design decisions from the outset.
Breidablikk Gården exemplifies an exemplary urban renewal initiative in Haugesund, where architectural innovation meets environmental responsibility. The building's facade brilliantly merges multiple functions into a cohesive system: it optimizes energy generation through strategic orientation, provides crucial shading, offers robust weather protection via its rainscreen construction, and contributes significantly to the building's aesthetic appeal with its dynamic surface treatment. This holistic integration demonstrates that advanced solar technology can be seamlessly incorporated into urban architecture, enhancing both the energy performance and visual identity of a city.
