Ranheim School, Trondheim School work is child s play New Ranheim School has a wonderful waterfront location in Ranheim, where the Sjøskogbekken stream flows into the Trondheim fjord. The project is the result of a design competition won by Lusparken Arkitekter in partnership with HENT in June 2008. The location and character of the site served as a compass for the design of the school building. The school buildings act as a structural screen to the north/northeast and create a calm and sheltered courtyard area to the south for the schoolyard. The northerly side of the building has a rugged exterior cladding of vertical Kebony-treated wood, horizontal timber windows and large glass bay windows, while the southerly side has a more refined cladding of painted wood tongue & groove panelling, lacquered facade profiles and white-pigmented concrete. The south-facing concrete acts as a thermal store and shades the school from the climatic effects of the sun, while the timber screen to the north protects the school from wind and rain from the north and northwest. The use of contrasting materials also divides the building into zones. Most of the classrooms are on the northern side, giving fantastic views over the Trondheim fjord and Fosen mountains. The windows and large glass Facility: Ranheim School Place: Trondheim, Norway Construction year: 2010 Architect: Lusparken Architects AS Fabricator: Ratdal AS Forum Sapa Building System 2-2012 bays capture the magical light from the north and give the teaching areas a sense of light and space. This side of the building also has classrooms for art, handicrafts and ICT, as well as the catering kitchen and administration space. The north/west orientation protects the classrooms from sun and radiant heat from the south. The goods entrance and staff entrance are located on this side. On the southern side are the school s communal areas, main entrance and individual entrances for years 1 7, a separate dining hall/afterschool club for years 1 4, the library, diet and health area, classrooms for the music & arts school, a music room and the school s assembly hall. The alternation between heavy masses of concrete and large open areas of glass brings light into the building but also creates a feeling of solidity and acts as a climatic buffer. The schoolyard is a continuation of the south-facing side of the building. The use of glass has opened up the school to its surroundings, and at the same time helped to create light and pleasant places as well as making it easy to orient oneself. The light and the location provide a great setting for learning.

Olsbergs Arena, Eksjö In the heart of wooden town Architect s description Olsbergs Arena is a combined sports and events hall situated in the centre of Eksjö, a Swedish town known for its many timber buildings. The arena was the winning proposal in an invitation-only architectural contest. It was built next to an existing sports hall and the distinctively designed and characterful hall can accommodate just under 1,000 spectators in the stands and about the same number on the floor during stage events. Particular emphasis was placed on solving the internal logistics and the interface with the existing sports hall, in layout and level, as well as tai loring the building to the sloping site and creating a building that clearly states its place in the town. The design reflects a desire to give the large asymmetrical masses the character of a timber structure combined with a pure classical form that is enhanced by the use of strong graphic colours. The junction between the new and the old halls takes the form of a communal wedge-shaped glazed lobby with entrances from two directions. At the main entrance the lobby extends into a light and inviting café area with glazed aluminium-framed panels mounted on a glulam frame.

Behrn Center, Örebro Gateway to Örebro Architect s description The Behrn Center is situated at the north entrance to the centre of Örebro, where it stands like sentinels, marking the gateway to Örebro. The two tower buildings have a sibling-like relationship, the 16-storey apartment block having cutaway corners and a solid core, while the 12-storey office building has solid corners and a transparent core. Each building is thus the opposite of the other, yet is also dependent on the other. Between the two towers is a four-storey glazed entrance that welcomes visitors. The centre also includes a large, light and transparent three-storey car park, crowned by terraced housing with an intimate green courtyard. Building high-rise developments in a central location such as this is a process that involves taking many different views into account, and the KLARA architectural practice was involved from the conceptual stage right through to completion. The process was both complex and fascinating, and the work was carried out in close collaboration with Per Johan Behrn, whose involvement is clearly reflected in the design of the building.

Clarion Hotel & Congress, Trondheim Setting the standard for energy efficiency

Clarion Hotel was awarded the Norwegian Eiendomsprisen 2012 (Real Estate Prize 2012) on the grounds that it represents architecture that engages people. The building embodies innovative solutions in design and art, as well as setting a high standard for energy efficiency. It is one of a handful of buildings in Norway to achieve an A for its energy rating.

Sapa 4150 SSG with screen-printed glass creates a unique and exciting facade. Sapa 4150 is used in the facade that links the masses together. The choice of the stars The hotel at Brattøra redefines the classical atrium hotel typology to a new and strong identity. The rooms are arranged/organized in four highly rational structures all oriented towards the perfect view. The rotation transforms the atrium from an enclosed central space to a 3-dimensional star shaped lobby space. Unlike the classical American and Asian hotel atrium where everything is exposed in a centralized and vertical, magnificent but onedimensional experience under a glass cover - the lobby is here given a 3-dimensional and dynamic spatial experience with a programmed roof, and a sequence of shifts between glimpse and panorama, intimacy and spectacular exposure. The hotel bears references to the local city fabric of Trondheim in the combination between the large structural lines and the small intimate ally. The project is a new type of city block - transformed by two forces: the orientation of the private rooms in relation to views - and inside: the dynamic shape of the common/collective/shared/public space in between with glimpses and passages towards the harbor basin, the fjord and the park. The hotel becomes a landmark without front or backside - but oriented towards the city and the fjord for optimal views in all directions. A lighthouse by the sea and inviting from the city. The lobby area at ground level belongs to the city and the public space The hotel room structure is dissolved at ground level to increase the public accessibility at ground level. The openness secures good orientation from inside and out - and internally between reception, elevators, lobby bar restaurant, exhibition area and conference. Cross connections, shortcuts and moving of common functions into the adjacent squares are encouraged: outdoor dining at the south-west faced terraces by the Brattøra basin, pause areas in the park, exhibition and entertainment can turn towards an outdoor arena and representative red carpet entrance with fountain and stone garden are facing the city. SUPERSTAR LOBBY, the exceptional common space of the hotel connects all the public functions from ground level to the upper floors - spanning between the rational hotel room structures. In the 3-dimensional lobby, the fireplace room, conference facilities and sky bar with roof terrace are shaped in a free form to take advantage of unique attractions towards the park, the Brattøra basin and the free view above neighbor buildings. The internal crystalline shape fragmented, but vertical sacral - gives associations to dramatic ice formations with cliffs, rips and ice floes.

Attunda Tingsrätt, Sollentuna Modern-day courthouse Stylish corner solution with stepped glass in Sapa Facade 4150. Architect s description An efficient judicial centre that combines police station, jail and courthouse was the central idea behind the special remit of the new courthouse: to create a modern and distinctive courthouse building that has its own integrity. The courthouse had to convey transparency, legal certainty and dignity. This transparency gave us the freedom to model with light and to contrast openness with shimmering expanses of glass and solid exterior surfaces. The courthouse looks towards the centre of Sollentuna and the commuter train station through its large glazed main facade. Its openness extends around three sides, and shafts of light penetrate the entire depth of the building thanks to the large areas of glass and atriums finished in white. The facade is buttressed to the north and south by transparent stairwells with glazing that wraps around the corners. The solid areas of the facade (which reflect noise from the railway) dissolve at each end of the building so that glazing and walls merge into each other. The wall surfaces hover above the shimmering glass. The entire building has a logistical layout that focuses on security and judicial certainty. It is a three-dimensional system solution that separates different groups right at the various entrances to the building. The use of modern technology allows the courtrooms to be quickly transformed into a combination of studio for audio and video recording and stage for playing back audio and video The interior of the building has a light but restrained colour scheme with colour accents that are co-ordinated with the interior and artwork.

Kuna Group, Rosersberg Dazzling entrance The sky is reflected in the massive blue facade like a mirror-flat pond. Step inside and the immediate impression you get is one of purity. No visitor is left untouched. The entrance serves as a business card for the Kuna Group, a manufacturer of water purifiers of worldwide reputation. It was only natural that the entrance to the company s new building in Rosersberg should radiate this purity. Barely visible design details and the choice of materials and colours all work in harmony to create the desired result. A sense of space is created in the entrance and parts of the offices by the projecting glass facade, which formed a key element in the concept. To create the large expanse of blue on the outside and the exceptional transparency and unobstructed view from the inside it was essential to use slim and elegant aluminium profiles in the construction of the facade. The exterior glazing supports also needed to be as flat as possible, since the facade glazing is self-cleaning in order to keep the reflective blue exterior as clean as possible. The result is a dazzling entrance and a glass facade that meets requirements for thermal insulation and draught-proofing, while also helping to create a beautifully designed but economically viable industrial building.

Vojens Fjernvarme, Denmark Solar heating plant Architect s description Vojens Fjernvarme supplements its district heating plants with a new solar heating plant. A 17,500-square-metre array of solar heating panels is now used to heat water for district heating. It can generate up to 10,000 MWh each year and will reduce CO 2 emissions by 1.5 2 tonnes per consumer. An administration building and production building for heating pumps have also been constructed alongside the new plant. The buildings have a south-facing pitched facade. This is clad with 240 square metres of solar panels, which have already generated 4,200 kwh in the first three months (January to March) of operation. This means that the electricity consumption of the heating pumps is partially met by a carbon-neutral energy source. A thermal shield covers the south and north faces of the building, but does not extend all the way to the ground on the south side. The east and west walls are inset beneath the overhanging roof, adding a certain elegance to the relatively plain exterior of the building.

Photo: Laurent Andrzejewski Sapa Facade 4150 SSG with Sapa Door 2074 around the entire base of the building. Hammarby Sjöstadspiren The exterior is constructed from horizontal feather cladding. The glazing alternates in five different shades of green and grey, and shifts in colour are emphasised as reflections from the water and sky play on its surface. A café is housed in the base, surrounded by walls of transparent and opaque glass. The glass exterior is completely maintenance-free. We strived to create an impression of lightness and slenderness, despite the fact that this is essentially a concrete building. The narrow base and pillars contribute to this. The building is slightly wedge-shaped, narrower at the rear and wider overlooking the water. The front of the building slopes gently inwards, creating a softer impression and influencing the shape of the balconies, giving them more depth. Bay windows at the sides give added space to the interior rooms and give the facade a dynamic appearance.
