Introduction The Fatburen building is situated in the Sodermalm District in Stockholm. The building dates back to the early thirties, and was hailed at the time of its construction as a model factory in the functionalist style. The building originally accommodated a meat packing plant, a grocery storehouse, a coffee roaster, a garage, a dispatch and a purchasing office as well as the main offices of the owners.

The building is currently undergoing refurbishment again by BSK Architects. The current plan is to include a commercial area along with the office environment. The Architectural Lighting Design students at the Lighting Laboratory in KTH were requested to propose lighting solutions for the entrance, atrium and a space of choice. The students were introduced to the space. They were given a project brief and intitiated to the concept of the space and the future plans. The developmental process was for a total of five weeks. Thorough analysis and testing was done before the generation of the concept.

Extensive plans for redesigning of the building were laid down. Gert Wingårdh, who is generally considered one of the most renowned living Swedish architects, was in charge of the project. The Fatburen Building was completely transformed, and is now Sweden’s post modern office building. Fatburen is an elongated plaster building punctuated by air wells and characterized by a horizontal alignment created by rows of windows running around the entire volume of the building. While featuring uniform floor plans designed for office use, the longitudinal section reveals a high level of complexity in the form if terrace-like projections and set-backs.

Client Brief The Client: BSK Architects BSK Architects was established 40 years back. They are involved with the design of cities, buildings and furnishings. BSK Architects specialise in projects involving offices, housing, higher education, healthcare buildings and trade. Some of their projects include the ABB business centre, Södertälje City Hall and the Central Post Office. Project Brief The main aim of the refurbishment of the Fatburen Building is to introduce a commercial area for retail and shops in the ground floor. The rest of the building will continue to house offices. Since the building is located in an area where there is a high pedestrian flow, it is essential to create a solution to attract people into the building for the success of the retail segment. For this reason, it has been proposed to build a ‘glass box’ as the entrance of the building from the north. This entrance would serve as the main entrance as compared to the south entrance used at present.

North Entrance: Before

Bridges to be demolished

Stairs to change to escalator

Concept The Fatburen building is uniquely shaped like the outline of a fish. Considering this, and the fact that the aim of the refurbishment is to create a flow and impulses of users within the building, the architects came up with the unique concept “jellyfish”. They would like to use the special characteristics of a jellyfish and reflect this in the lighting design on the space while at the same time maintaining the industrial integral character of the building. Suggestions for choice of textures were also requested.

North Entrance: After Fatburen Building is fish-shaped

Presently the ground floor is divided into many sections, and has a series of entrances and areas. It is not possible for the users to move freely from one end of the building to another. To create a feeling of openness, all the obstructions in the main corridor will be removed. The users will be able to perceive a sense of flow in the building. The bridges across the corridor shown in the pictures will be demolished too. The staircase as shown in the picture will be converted into an escalator, thus keeping the functionality while providing more space. Client’s moodboard: jellyfish_industrial

Analysis_External Location

Daylight Analysis: Exterior

The building is located in the center of Stockholm, in the Sรถdermalm district. The Fatbursparken park is adjacently located in the north of it. The building is surrounded densely by buildings on the other three sides. It is easily accessible by underground metro and buses, as there are stations very close to it. Most of the pedestrian traffic is along the south road as shown in the picture.

Sun Path in Stockholm

The figure above illustrates the movement of the sun over different times in the year. While analysing the effect of the daylight on the building, it was found that since the main glass box is situated in the north, there will not be any direct sunlight at any time of the year. Hence it was considered necessary to not have any kind of shading or obstruction the design of the glass box and maintain the properties of the glass. The rest of the building has existing external sun shading in various areas. A simple nosky line analysis in the South of the building shows that there is not much penetration of sunlight in the space. This is because the building is surrounded with various urban elements in all sides. Hence, the aim was to optimise and highlight the daylight in the space.

Analysis_Internal Artificial Lighting The building has a wide range of fixtures used in different areas. Very often the fixtures were not coordinated, and there seemed to be a wastage of light and energy. No sense of orientation was perceived through the whole building. Measurements were carried out at different areas and it was observed that there was a wide variation in the lighting, and the natural lighting from the skylights were not utilized and did not seem to reach the ground. The light levels ranged from 238 lux under the skylights to 22 lux under the arcades. The measurements were carried out on an overcast day in February

Natural Lighting After analysis of the measurements, a virtual analysis of the variation of daylight over the course of a year was carried out using the software Relux. The renderings were calculated for three main dates: the equinox- March 21, summer solstice- June 21, and winter solstice- December 21. The results can be seen below.

March 21

June 21

Measurements

December 21

As can be seen above, the light levels under the skylights vary from 75 lux to 500 lux over the course of the year. Although there is a drastic variation in the levels, the distribution for the most part remains the same. This shows that the areas under the skylight retains its character for the most part of the year.

Analysis_Conclusion The building was thoroughly analysed from the interior and external aspects. As detailed earlier , effects of natural lighting in the space were taken into effect along with the variation over the course of a year. No se The users seemed to find it difficult to find a sense of direction to where to go and how to get to different spaces in the building. The circulation elements between floors could not be recognised, and needed to be emphasised. There were some interesting architectural features like different ceiling heights and skylights. These features did not seem to be highlighted. There was also no perception of height of the structure, and the different levels that existed.

Summary of the Analysis •

The luminaires used seemed uncoordinated and had different aesthetics and profiles. There were various colour temperatures in the same space, and this clashed with the overall perception of the interior space. There are arcades on either side of the main atrium that would serve as the entrances to the shops and can help continue the concept, and emphasise the openness of the atrium.

Many luminaires were placed directly in front of walls, were not visible to the users and did not seem to serve any purpose. This is a waste of precious energy and money. This aspect had to be changed. The light levels in areas other than the area under the skylights were very low, and were not uniform at all. This gave the users a sense of being in a ‘cave’. This is surprising as the building has a very open structure, with open air wells and skylights.

introduction

analysis

concept

The space also had very unique features that could be accentuated and highlighted. The skylights seemed to be the prime feature of the space, and they can be used to differentiate spaces or create ‘impulses’ or sections in the main atrium with the help of the natural light that reached the floor.

Orientation No sense of direction in the space for the users

• Height There is no perception of the height of the building and the structures within •

Light Levels The light levels from the artificial lighting varied on a large scale, and gave a wrong impression of the space.

Energy The lighting solution at present is not energy efficient as there are unnecessary luminaires

Colour Temperatures There were uncoordinated and very varied colour temperatures in the same space that gave a chaotic appearance

• Light Fixtures The light fixtures that are installed there are very different in terms of aesthetics and do not seem to match eachother or the concept of the space.

Concept_Vision

Balance between Formal and Playful To reflect the unlikely combination of offices and retail in the same space, there should be a balance between the formal and playful elements in the space. This would also indicate clearly the various areas in the same space implicitly.

Openness To take advantage of the feeling of openness created by the skylights and extend it to the rest of the space, so as to create the same impression throughout the building. This would also take into account the recent changes in the structure of the building such as demolishing the bridges between the airwells and accentuate it.

Energy Efficient Design To create a lighting solution that is energy efficient. Also consider the effect of natural lighting in the space, and complement it with artificial lighting.

Separation of Spaces Create a clear separation of the spaces utilised for retail and offices. Clearly define the retail areas, circulation areas and meeting points.

Orientation Make orientation and circulation easier for the users in the space. Provide vertical and horizontal directionality. Clearly accentuate and differentiate the spaces with different purposes, so as to clarify it to the users.

Highlight the Circulation Elements Solve the problem of lack of vertical orientation by clearly defining the escalators, elevators and stairs.

Attraction Attract pedestrians into the building and draw attention to the building. Make the building a landmark in the area.

Coordinating Colour Temperature The colour temperature of the lighting will be coordinated and correspond with the overall concept.

Concept_Detail The Fatburen building is renowned in Stockholm for being one of the earliest post modern buildings in the area. It is a prominent and prestigious location for offices. The renovation project being carried out by BSK architects serves to maintain this image in the minds of the residents while at the same time carve an identity that relates it to a premier retail destination. Keeping in line with the conceptual intention of the client, we want to create an iconic image for the building that is unique to it’s character and can be instantly recognizable. Glassbox Entrance The main feature of the refurbished building will be the ‘glassbox’ entrance at the north of the building. Since this is the main access to the building from the pedestrian flow, it will be the main highlight of the structure and will set the character for the rest of the interior of the building. The concept for the glassbox will draw from the glow and distinct colours of ‘jellyfish’. As mentioned earlier, jellyfish is the main idea for the building as described by BSK Architects.

introduction

analysis

concept

The glassbox lighting will be controlled to symbolize the upward movement of a jellyfish in the water. This animation will take place at dusk and will serve as a daily event that can be observed from the surrounding areas. The glassbox will glow and pulse in a variation of colours. This concept of ‘glow and impulses’ will be carried on through out the building.

Internal Lighting Circulation Elements The vertical circulation elements in the building will be highlighted to provide directionality and orientation in the space. The staircase, escalators and elevators will be emphasized by defining it with coloured lighting. The colour will be drawn from the glow illuminating the glassbox and will extend the concept inwards. The unique colour designated will specify to the users easily the circulation elements and reduce the lack of direction in the space.

Concept_Detail Atrium The main feature of the building- the skylight, will serve as the highlight in the internal spaces. The main atrium can be perceived as sections because of the spaces defined by the artificial and natural light. The sections that are defined by natural light can be identified as impluses repeated through the length of the corridor. The artificial lighting will be provided pendant luminaires that will complement the daylight. These pendants will also have uplighting so as to highlight the unique structure of the building. This solution will enhance the feeling of openness in the area. Arcade The arcades near the retail section will have a playful mood. Coloured spotlights will be used to create vibrant glowing areas on the floor. Users walking in this area will be able to participate in a game of colourful shadows. This unique effect will create an identity for the space and help separate the office areas from the retail areas. Different textures will also be used to highlight the separation.

To emphasise the glow of the arcades, they will be defined by dark walls and ceilings and light floors. This differentiation also serves to clearly separate the areas that are used for different purposes. Dark floors and ceilings help further the purpose and the idea of the concept. However, the perception of the space by the users is of utmost importance in the process of design. To understand the views of users in a darker space, surveys and observations were carried out in a similar space with a comparable purpose and interiors. The analysis was carried out in Mood Mall, Stockholm. The pictures below give a glimpse of the interior of the mall.

Surveys were carried out among the 35 users of the space. When asked to describe the space, the most common answer was ‘cozy’ and ‘luxurious’. It was found that not only do users like the darker atmosphere in a retail environment, they actually prefer it to the harshly lit environments in conventional malls. A pie chart showing the results of the survey is shown in the figure below.

Lighting Scheme_Entrances North Entrance

The main entrance of Fatburen building. The main purpose of the lighting design is to create an iconic image that is easily recognisable. Concept Create a glowing effect that pulses in the distinctive colours of a jellyfish. Also initiate the lighting at dusk with a rising effect imitating the vertical movement of a jellyfish. This daily event will serve to attract people from everywhere. Once the phenomenon is observed, it will be easily identifiable uniquely with the Fatburen building.

Glassbox in the day

Lighting Scheme This remarkable glowing effect will be achieved by placing an led strip directly along the edge of the pane of glass. This effect will not affect the transparency of the glass during the day and at night will give a completely different character to the same space.

Lighting Scheme_Entrances The lighting will also be controlled to gently pulse, fade and glow, giving an ethereal aquatic affect to the entire space.

During dusk, the luminaires will be controlled to imitate the vertical movement of a jellyfish. The colour gradient will rise from the ground to create a sensation of the building ascending.

For the interior of the south entrance, we propose suspended pendant luminaires that are used in the atrium to create a sense of continuity with the rest of the building.

Lighting Scheme_Entrances South Entrance Concept The main idea is to provide a sense of orientation to the users in the space. Lighting Scheme The south entrance will have ambient daylighting from the glass windows and entrances. The lighting in this space will serve to give direction to the core of the building where the retail areas are located. Dimming controls will be integrated to the lighting to complement the natural lighting, so that the system is energy efficient without compromising on the light levels.

The reception area will have higher levels of lighting to draw attention to it. The ‘game of shadows’ concept that will be elaborated later will also be the main element in this space.

Lighting Scheme_Circulation Elements Concept To orientate users within the space. Highlight vertical circulation elements and provide directionality in the space. The staircases, escalators and elevators in the space will be emphasized in a unique colour so as to be easily identifiable.

Escalators The lighting will be installed in the frame outside the actual escalator. The same solution of coloured LED strips will be used.

Lighting Scheme Use recessed led strips to frame the circulation elements, while at the same time provide ambient lighting.

Elevators The frame of the elevator will be highlighted to attract attention to the space, and to highlight the verticallity of the space.

Colour Chosen The colour chosen for the instalments is a shade of blue to keep in line with the aquatic concept and to create a sense of continuity from the lighting in the glass box. Staircases The staircases will use lighting that will be installed under the handrails. This will provide a glowing effect while at the same time distribute enough light levels for using the stairs. This solution is unobtrusive and is easy to maintain. The luminaire used will be coloured led strips.

Lighting Scheme_Atrium Concept The main concept of the atrium is to emphasize the feeling of sections or impulses brought about by the difference in lighting between the natural lighting from the skylights and the artificial lighting. This brings about an industrial feel to the space. The atrium consists of airwells with the office windows overlooking the space, and has a feeling of openness. The concept serves to utilize this perception by using uplighting and downlighting. The pendants will be hung at different heights to bring prominence to the different ceiling heights.

Luminaire The luminaire is custom made to serve the purpose of the space. It consists of two light sources placed at the bottom and top of a cylindrical construction. The aesthetics reflect the industrial concept of the atrium.

Lighting Scheme Pendant luminaires with uplighting and downlighting will be suspended at different heights. The uplighting emphasizes the different heights and shapes of the structure while the downlight provides ambient lighting to the floor.

Lighting Scheme_Arcade Concept The aim of the arcade is to create a ‘glow’ along the sides of the atrium. The arcade will provide playful elements on either side of the main corridor. The colours used for the glow will be a continuation of the colours of illumination of glassbox. The spaces will have darker textures to highlight the retail areas. Lighting Scheme The aim is to create a playful interactive effect on the floor using colourful shadows. This is achieved by using spotlights with different dichroic filters aimed at the same area. The interaction of the coloured lighting will give an effect of multiple shadows. The floor seems to come alive with the shadows, and provides a fascinating phenomenon that is memorable for the users.

Textures This effect is best observed when the flooring is light grey in colour and has a matte finish. Also it is suggested paint the walls and pillars till the first floor a matte black. This serves to separate the retail area from the office spaces. It is also advised to keep the shop windows at a height of 250mm from the ground level, so as to not disturb the effect of the shadows.

Lighting Scheme_Conference Room The conference room is situated in the southern part of the building in the fourth floor. The space consists of four meeting rooms and a lounge area along with a reception. The area also has ambient daylight from the windows. Concept The aim of the lighting design is to create an exclusive conference area that consists of lounge, reception and four conference rooms. The lighting ambience of the space would reflect the functionality of the space while complementing the ample natural light streaming in from the southern windows.

Conference Room The four conference rooms have similar lighting configurations. There are three main types of lighting that have been incorporated. Task Lighting: The task lighting is provided by a distinctive flexible luminaire that can be adjusted according to the user’s requirements.

Since the conference area has a plethora of functions, there are different solution for different purposes. The main conditions that have been considered are only daylight, lighting during a video conference, and task lighting during a meeting.

Reception The reception area is brought into focus for the visitors of the space by making it brighter than the surrounding areas. This is done by placing luminaires above the reception and emphasising the space so that the eyes are automatically drawn to the reception. Lounge Area The lounge area consists of seating areas, coffee tables and a display area for magazines and notices. The aim here is to create a cozy atmosphere in the space for users to rest, network and interact. This is achieved by using lighting in a warm colour temperature in the space. The luminaires used are a combination of pendants and recessed lighting. All the lighting is controlled to complement natural lighting, and incorporates timed dimming.

Flexible Task Lighting Accent Lighting: This lighting will be in use during a video conference or a presentation. It is provided by cove lighting installed vertically on two walls of the conference room. The cove lighting is basically high power flourescent lighting that can be dimmed according to the needs of the situation.

Podium Lighting: This is to bring the focus to the speaker at the end of the room. The area is lit up with spotlights placed directly above the podium to draw attention to the main presenter.

Testing_North Entrance Intention To create the concept of a glowing glassbox by experimenting with different types of glasses and light sources We finally achieved the effect we needed with a pane of glass that had a frosting effect.

Effect Desired To create an effect of ‘glow’ with glass and the light source. The main aim was not to have a visible light source but still have the lighting effect in the space. Physical Testing Process The process involved investigating different types of glass, and the kinds of widths that are available in the market. We decided to use an LED strip as our test light source to experiment with the different kinds of glass to achieve the effect we desired. It involved a visit to a reputed glass supplier and familiarising ourselves with the physical properties of glasses available.

Conclusion The experiments proved that a frosting effect was required in the glass to get the glowing effect that we required. We propose to use the glass solution Crimetal® by the renowned Spanish glass manufacturer Cricursa. We also contacted a few LED accent lighting manufacturers, and the most suitable solution was the Archibar luminaire by the Italian manufacturer Studio Due. The luminaire has RGB LEDs and can be controlled by DMX and DALI control systemsThe manufacturer suggested the luminaire as it has been used in similar projects worldwide, and will make a custom size for the specific lengths required for this project.

Testing_Circulation Elements Intention To determine the comfortable amount of light levels in staircases and lux levels. Effect Desired A coloured glow to indicate vertical directionality and highlight the circulation elements in the space without overlighting and creating a harsh environment.

Conclusion The analysis helped decide the kind of lighting that we would need for each circulation element. All the vertical circulation elements will be differentiated by the distinctive blue colour. Stairs: We will be using lighting integrated into the hand rail of the stairs. The solution that was most suitable is Viva from iRail with integrated LEDs in blue.

Elevators & Escalators: We will be using recessed lighting with coloured LED strips with a diffuser. The most appropriate lighting solution for this is the Minimal system by XAL which can be configurated according to the requirements.

Physical Testing Process We analysed different spaces across Stockholm to see the most ambient amount of lighting required for staircases and escalators. Measurements were taken for further analysis. The spaces studied are the Central Station, an arbitrary apartment building , a retail complex, and a university. The lux readings varied from 25 lux to 108 lux, with an average reading of 85 lux.

Testing_Atrium Intention To create an industrial feeling in the atrium space that will blend in with the open atmosphere. The lighting solution will integrate daylight and artificial lighting with the help of dimming options. The solution to this is to create a luminaire that has both uplight and downlight in the same unit. Effect Desired A minimal lighting fixture that provides both uplighting and downlighting and is compatible with dimming controls. Also should be able to be suspended at various heights.

Physical Testing Process: Uplight We needed to select a luminaire that had a uniform distribution at a distance ranging from 2m to 5m. We carried out testings with several beam angles of a 25W LED module from Xicato. We finalised on 60 degree, 30 degree and the 15 degree options.

Physical Testing Process: Downlight The process involved testing different kinds of lamps to achieve the distribution we want without compromising on the light levels and the energy efficiency. We concluded that LED lamps were the best choice for this. Next, different luminaires were to be tested to achieve the required light output at different heights required- 12metre, 8 metre and 4 metre. The luminaire that best fit these requirement was the 35W LED downlight from the brand LTS with beam angles of 15 degrees (for 12m) and 35 degrees (for 8m and 4m).
