Haikou Tower Competition Winner | Henn Architects

Henn Architects have won the first prize in the international competition to design the Haikou Tower in Haikou, .

Masterplan

Haikou Towers are projected to become the heart of the new Central Business District of Haikou, the capital city of Hainan, a tropical island in the in the South China Sea. The Masterplan comprises an ensemble of 10 Towers ranging from 150 to 450 meters height with an overall building area of 1.5 million square meters.

Two facing series of towers line up along the central axis of the new Central Business District and culminates in two landmark towers framing the central plaza of the district. On ground level the office towers are connected by a continuous undulating podium that accommodates the adjunct commercial facilities. The public realm between podium and boulevard expands with lush green spaces and water basins.

Haikou Tower

Form and structure of the 450m high tower have been directly informed by the program requirements of the building and the drive for an efficient structural scheme. The occupant needs for an office space and hotel room are distinctly different and have led to a shift in the structural system at the boundary between the two functions.

The shift in systems occurs at the hotel lobby area in the form of a large outrigger truss. This truss is purposefully exposed and integrated into the architecture to provide a clear distinction between functions and structural systems and is a key feature of the overall design.

The requirements for the office levels called for long span floors with column free interiors. This led to a megacolumn and megabrace solution in conjunction with a large core. In order to maximize the flexibility of the internal spaces, these megacolumns are pushed to the eight exterior points of the building, inclining and rotating with the form. Core and megacolumns carry the majority of the vertical loads. The large megabraces carry the horizontal loads due to wind and earthquake loading.

For the hotel floors there is a greater requirement for unobstructed views. To avoid any cross bracing on the perimeter of the building a structural system relying only on the core and perimeter columns is adopted. The perimeter columns are tied back to the core via a rigid connection at each floor plate and a large capping truss at roof level. The internal space of the core itself is designed as a full height atrium. To increase the openness of this space, the concrete walls employed for the office levels core are replaced with a steel diagrid.

The lower two thirds of the towers are reserved for office use with a total floor area of 185.000 square meters. The hotel lobbies are located on the 72nd floor with three floors of hotel service programs underneath. From the 77th to the 100th floors the hotel offers more than 46.000 square meters of floor space for guests. The sky lobby and the observatory floor are located on top of the tower.

Facade

The building height of 450m called for an intelligent, highly performative building envelope. The main requirement of the facade system is to react to differing sunlight conditions depending on the building’s orientation.

The proposed facade achieves this with a panel unit system which is divided into two parts – an upper opaque part that blocks sunlight and a lower transparent part. The opaque spandrel panels provide both external shading to reduce cooling loads and energy production by a photovoltaic coating on the south facade. The transparent glass facade in the lower part maximizes the use of daylight. The division in each facade units allows to fold in and out.

The folding angles vary according to the different sun-shading requirements, from north to south, from bottom to top. The increase of the folding angles allows for a smooth transition from the flat units on the north side to units on the south facade with a maximum angle of 30 degrees. The continuous differentiation of the facade harmoniously blends with the large-scale structure of the tower.

Greenland Zhengzhou Towers | Brininstool, Kerwin+Lynch

The Greenland  are unbuilt towers designed by Brininstool, Kerwin and Lynch in 2010.  According to the architect description, the unique forms are “rooted in cultural influence, in which the massing is identifiable with the mountain formations found outside of Zhengzhou. The expression is balanced between historical symbolism and contemporary innovation.”

With an area that exceeds 6.5million square feet, this massive mixed-development was proposed to house a variety of programs, including office space and a five-star boutique hotel that occupies the top floors of the shorter tower on the south site.  BKL was involved with the design of the complex on all scales, from the site considerations the lighting design of the hotel units.  In addition to the typical hotel amenities afforded by luxury hotels (ballrooms, lap pools, spa, fitness center, etc.), the complex is decidedly Eastern, with meditation gardens and outdoor terraces.

The tower is constructed of  and steel with a glazed curtain wall system.  The dynamic frame is complemented by the light and delicate skin, which alternates between low-e vision glass, opaque spandrel glass, and metal scrims.  This approach, in addition to light shelf usage and southern-facing PV panels, are huge components of BKL’s proposed sustainability strategy.  The building was to rely primarily on passive strategies of harnessing and shielding the sun for energy savings.  In addition to addressing the various proposed occupancy types, this also capitalizes on the sweeping views of Zhengzhou and capture necessary daylight.

China Diamond Exchange Center | Goettsch Partners

Architect: Goettsch Partners
Location: Shanghai, 
Project Year: 2005-2009
Photographs: 1st Image

The China Diamond Exchange Center is a 535,500 square foot office complex designed by Goettsch Partners of Chicago, Illinois.  Located within Shanghai’s sea of massive and often overstated high-rises, this modest-by-comparison structure is brilliantly detailed, appropriately scaled, and aesthetically beautiful.  The complex was completed in 2009 with the help of associate architects Zhong-fu Architects.  The Diamond Exchange Center is sited within Shanghai’s Pudong district, an international financial and commercial hub and houses both the Exchange and additional relative tenants.

In addition to office space on the upper levels, the building includes retail on the ground floor and a second floor that features the elevator lobby, exhibition space and a restaurant.  According to the architect description, the building was conceived as two rectangular office slabs joined by a skylit atrium.  One of the two office slabs is dedicated to the members of the China Diamond Exchange, while the other tower houses the remainder of the complex’s tenants.  The separation of tenants allows for secure transport for Diamond Exchange members within their own tower, thereby eliminating any potential security breaches for the high-profile office functions.  While distinct with regards to program,  both towers are clad with exterior  and contrast the transparency of the atrium.

The atrium is the undeniable focal point of the building, featuring a 66×230 foot cable-supported curtain wall.  The immense scale of the atrium is an impressive entrance to visitors and employees and provide access to the elevators that serve as the complex’s primary vertical circulation arteries.  Not only is the atrium an impressive architectural statement, it is also integral to the daylighting scheme of the complex and brings natural light to the relatively narrow 20m wide floor plate of its abutting towers.  The primary tenants’ core business inspired the design, with  diamond-shaped elements featured throughout the scheme — these elements includes the atrium’s glass skylight, the geometry of the entry canopy, and the main lobby floor pattern.

Story by Charles Moxham

Even in a substantial Grade A office tower, the potential reallocation of spaces can be a major design consideration. Together with clean, contemporary architecture, generous floor plates, and ergonomic pedestrian flows, there should be the option to repurpose the spaces as business needs evolve.
The China Diamond Exchange Center, designed by Goettsch Partners and commissioned by Shanghai Lujiazui Development Co, stands tall on Century Avenue – the main boulevard in Shanghai’s Pudong district and the city’s financial and commercial hub.
The 15-storey, nearly 50,000m2 building provides space for the China Diamond Exchange, which currently occupies one side of the building, as well as other related tenancies. In addition to office space on the upper levels, the building includes ground-floor retail facilities, with the elevator lobby, exhibition space and a restaurant on the floor above.
Partner at Goettsch, James Zheng says the building was conceived as two large rectangular structures connected by a central glass atrium, which looks like a giant sparkling diamond sandwiched between great slabs of coal.
“The core business of the major tenants inspired the design in other ways, too,” says Zheng. “Diamond-shaped elements can be seen in the atrium’s glass skylight, the structural geometry of the entry canopy, and the lobby floor.”
Essentially, the architecture of the China Diamond Exchange Center is a tribute to its stock in trade – an aesthetic that also helps it stand out from other, in many cases taller, structures nearby.
A colour palette of black, grey and red dominates the building. The two office blocks are fronted in black, which provides hard-to-read surfaces that disguise the intakes and exhausts of the mechanical systems. All building systems were pushed to the outer areas of the building in the pursuit of large, uncluttered floorplates that are both attractive to tenants and practical in terms of reconfiguring offices as required.
Exposed metal elevator cabs, stainless steel cables and other, more reflective surfaces lend a subtle contrast in grey. In addition, there are several splashes of red within the decor. With many positive connotations in Chinese culture, this colour brings a sense of warmth to the minimalist spaces.
“The translucent glass atrium and open elevator towers are the central focus of the building,” says Zheng. “Besides evoking the strength and sparkle of diamonds, the atrium creates a sense of business transparency. At the front and rear of the building, 20m x 70m net walls supported by cables admit maximum light into the cavernous central space.”
The three elevators, in the middle of the atrium, climb to sky bridges on all levels that lead to both towers. The activity of the elevators is not only visible from the lobby but also from outside, through the gleaming net wall. Similarly, activity on the street can be seen from within the atrium, further animating the ground-level spaces.
The architect and developer had far-sighted plans for this tower and the elevator banks are a clue to the ongoing viability of the building.
“With diamonds being such a valuable commodity, staff working in that tower enter through a screening room and then travel up to their floor on separate, secure elevators away from the public eye,” says Zheng. “So, while the central elevators appear to service both sides, in reality they currently only take people up to the multi-use tower.”
It is envisaged that in the future, the China Diamond Exchange will occupy both sides of the building, and at that time all levels and both towers will be accessed, via security, by the central elevators.
“We could have built separate elevator shafts for both towers, but the long-term view dictated that we build the central, feature elevators that could eventually be utilised by all,” Zheng says.
Topping the towers – and adding to their adaptive use – are upscale penthouse spaces that are likely to evolve into executive offices or exhibition areas.
“Everything about the China Diamond Exchange Center was designed with an eye on the future.”

Fabrikstrasse 15,Basel | Gehry Partners

Fabrikstrasse 15

Sunlight penetrates the protective glazing of Frank Gehry’s Fabrikstrasse 15 — even through the photovoltaic-cell panels of the roof — filling the interior with light. A skylight integrated into the campus grounds (center) brings daylight light down into the lower-level auditorium above the stage.

Fabrikstrasse 15

Completed in 2009, Frank Gehry’s Fabrikstrasse 15 is an icon on the growing Novartis Basel campus. In the evening its brilliant sculptural form is underscored by layers of light — all on the interior — that gently wash the facade, illuminate the workstations, and glow from within its core.

A central atrium brings daylight to interior Gehry-designed workstations and glass-enclosed “private rooms” at the heart of the office floors. Adjustable metal-halide up and downlights illuminate this space when necessary and reflect off overhead white lamellas (a radiator-like array that also diffuses sunlight from the glass roof and provides radiant cooling).

Photovoltaic cells are integrated in the glass roof surfaces to generate renewable energy for the electrical lighting and to provide an effective sunscreen against solar gain in upper levels of the building.

Below grade, a 600-seat auditorium can be divided into two sections. It features: a wood-lined acoustical wall perforated with a subtle graphic pattern by the New York–based graphic design firm 2×4; a flexible glass-ceiling system that evenly distributes the light of cool, daylight-quality linear fluorescent lamps; and amber LEDs that create an atmospheric glow into the room from under the seats.

Breaking the bounds of of Vittorio Magnago Lampugnani’s master plan, Fabrikstrasse 15 by Frank Gehry stands in a surprising juxtaposition to the serene array of rectilinear buildings that dominate the Novartis campus. It is located at the geographic heart of the campus, in full view of the company’s renovated 1939 Forum 1 International Headquarters building, and across the street from a refined stretch of porticoed offices and labs by Adolf Krischanitz, Rafael Moneo, Lampugnani, and Yoshio Taniguchi. The highly visible, independent site gave the architect freedom to exploit his expansive, free-spirited style.

Relieved from many of the constraints binding the other architects, Gehry and his team created a voluminous 209,896-square-foot building that manifests the Novartis commitment to an open and environmentally responsible workplace in its crystalline transparency and intricate sustainable strategies.

Anchored to a load-bearing reinforced-concrete skeleton that sits on a rigid 56-foot-deep basement box, the building’s structural steel shell supports an active triple-glazed envelope that is tied to its natural ventilation and lighting systems through a centralized building facility-management system. Like a finely tuned machine, the building performs unobtrusively to provide comfortable surroundings for its occupants. Sliding glass doors on the ground floor and operable windows discharge excess solar yields and facilitate the flow of outside air, aided by a mechanical fresh-air system around the perimeters of the upper levels.

Home to the human resources (HR) department, as well as to a top-floor campus reading room, a 600-seat multiuse auditorium and IT learning center (both below grade), and a ground-floor restaurant and café that spill out onto the campus green, Fabrikstrasse 15 is a hub of activity. The warm, wood-lined interiors feature whimsical LED-backed-veneer media-columns and modular Gehry-designed furnishings and workstations.

In accordance with Novartis chairman Daniel Vasella’s versatile “multi-space” office concept, the architects arranged the HR floors on the five upper levels with flexible, open-plan work spaces and glass-enclosed “private rooms,” bisecting them with a central atrium and serpentine stainless steel stair to bring light down through the core of the volume. A series of skylights strategically inserted into the floor and grounds around the building carry daylight to the café, the lower-level learning center, and the auditorium stage.

According to Gehry Partners project architect Kamran Ardalan, daylight is harvested and managed in several ways: The low-E glazing is articulated with ceramic frits on the facade to reduce direct solar gain; an orchestrated series of low-E-coated, saillike interior shades operate on sensors to minimize glare and additional heat; and sound-absorbing lamellas under the roof diffuse sunlight and further compensate for the thermal load by serving as cooling radiators filled with slightly chilled water. In addition, photovoltaic cells integrated into the glass roof panels not only generate enough power for the building’s electric lighting, they supply an additional layer of solar shading.

“The amount of daylight inside the building is consistently monitored,” says Ardalan. Electric lighting is used only when there isn’t enough daylight, he adds — and to illuminate the building at night.

Looking frosted and icy-white on a bright afternoon, the building assumes a brilliant clarity as the sun sets, revealing its inner workings like a child’s “visible engine” kit. This effect stems from a perceptive, energy-efficient electric lighting scheme by the New York–based L’Observatoire that balances program and architecture.

It was a challenge, says principal Hervé Descottes: “It’s such a transparent building that you could lose its sculptural aspects.” To achieve a soft, lanternlike glow, Descottes and his team layered the structure with light from within.

Initially, they created a layer by washing the mullions of the facade with metal-halide uplights installed inside the perimeter of the first level. Then they added a second layer of ambient and task lighting on the office floors, using compact fluorescent lamps. Here the lighting team kept the general light levels lower than usual to emphasize the glow of the fixtures at each desk, a tactic used to establish an intimate ambience for employees.

Next they installed linear fluorescent fixtures to wash the wood walls on all the levels, and inserted cool T5s above awninglike glass ceiling panels in the auditorium that create a seamless transition with the sunlight penetrating the skylight.

Last, they lined the atrium with adjustable metal-halide fixtures from the ground floor up to the roof, directing them up and down, and reflecting light off the white lamellas. This move, perhaps the most important, brightens the center of the building and underscores its voluptuous form.

During a recent visit on a warm and sunny summer morning, the offices were bursting with light — without a hint of glare — and wonderfully temperate minus the chill of air conditioning. A holistic tour de force, Fabrikstrasse 15 is illuminating in its transparency and ability to harness the aura and power of light — both generated and from the sun. Such a building defines the spirit of Novartis as an enlightened workplace.

Google HQ | Ingenhoven Architects

Google to Build Headquarters in Mountain View Google Mountain View © Ingenhoven Architects

The rise of Google Inc. Is a phenomenal success story that has just begun. More than 80% of all searches world-wide are done using Google. The growth of the company is mirrored in the growth of the Google Campus in Mountain View/California, the Headquarters of Google on Charleston Park. Google is proud of its corporate culture and offers attractive workplaces in order to attract the best talents from all over the world. Google wants to build a showcase sustainable building. On the adjacent site between Charleston Road and Shoreline Boulevard a large new building will be built for Google. The site demands a building with autarkic geometry. As part of an international selection process ingenhoven architects won the commission to design the new HQ. The client’s brief was simple: It should be the best and „greenest” building in the world! The new building will be home for 2.500-3.000 engineers and scientists as well as the Headquarters. The Google Headquarters is the first project for ingenhoven architects in the US and Google builds for itself for the first time. Google‘s success depends on engineers, inventors mathematicians, IT-experts and scientists of all kinds. The building should reflect their different approaches and enhance convenience and productivity. The building will be „lively, fresh, simple and flexible” and offer healthy, communicative and effective workplaces and have „buzz“. The architecture is an expression of the „corporate culture” and at the same time a model for sustainable architecture in the broadest sense surpassing the LEED-Platinum-Standards with its holistic concept. Construction will start in 2012.

Westraven, Utrecht | cepezed architects

In a world fixated on the sustainable possibilities of new construction, the far greater environmental benefit of upgrading our existing building stock is often ignored. Westraven indicates what is possible if we address this issue.

The Westraven Office Complex in Utrecht, the Netherlands, is a combination of a renovated existing building and a new extension for the use of several divisions of the Dutch Department of Public Works. The program includes office space, conference facilities, a national meeting center, a communications center, and a “future center” named LEF for the Department of Public Works. This existing 85-meter (279-foot) tall construction has been radically renovated and reorganized, and a stretched out four-story podium has been designed around the base of the building. Various functions and facilities are based in large, open spaces in the podium, which are inviting for both meeting places and casual encounters. Much attention has been devoted to obtaining perfect equilibrium between low energy consumption and an optimum working climate. The architecture, technical installations and construction physics are fully integrated, which significantly contributes to the overall sustainability of the complex.

The Original Westraven

Westraven is an area to the South of the centrally situated Dutch city of Utrecht, located between the Amsterdam-Rhine Canal and the intersection of two major motorways, the A2 and A12. It was built in the early 1970s, utilizing a so-called jack-block system, which at the time was a cutting edge construction technique of British invention. This method required that the roof had to be constructed immediately after the foundations and basement were completed. Once the roof was completed, the core, which was made out of prefabricated concrete blocks, was constructed. This means that the entire unit was jacked up to create the space needed for a new layer of blocks and the top floor.

Figure 2. Existing high rise tower

As a result, the construction of the building was gradually elevated at a rate of two floors every three weeks.

Regardless of its revolutionary construction, Westraven received a generally negative critical response, which over the years only became stronger. One reason was the strong winds at the main entry which frequently hindered people and an alternative entry had to be used frequently. Also, the monolithic office block appeared distant and the working conditions inside were below par. The substandard climate control and a dark, stuffy atmosphere also played an important role in this negative criticism.

Because of the negative feedback, but also its central location, it was decided that the building was to be renovated and that it would be expanded to accommodate additional divisions of the Departments of Public Works. In addition to improving climate and the working environment, the new complex had to be open and transparent while also reflecting a certain prominence in the city. Moreover, Westraven had to set an example as a landmark of sustainability.

Opening up

The tower has been stripped to its concrete skeleton, which has been completely reused. Five large voids, of 6 meters (19.7 feet) wide and 5 meters (16.4 feet) deep, were created by removing floor segments of three successive floors, alternatively along the western and eastern façades. Now users no longer enter a dark and nondescript space when they exit the lifts at the core of the tower. Instead, they are met with an abundance of light and splendid panoramas over the Utrecht area. This not only improves spaciousness and scale, it also helps users to orientate themselves. Moreover, because of the newly created voids, the different office floors are interconnected, which contributes to both internal communication and spatial diversity.

Figure 3. Transparency and daylight in the lobby

From the outside, the voids are large rectangles of solar-control glazing, which immediately grabs  attention because it visually stands out amidst the horizontal rhythm of the rest of the façade. As such, they serve as an important identifying element of the building.

The new thermal façades are made of floor-to-ceiling glass. This not only improves the views and the amount of daylight into the offices, but it also ensures that the occupants will always move towards light when they pass through the hallways. The interior arrangements are fully flexible, comprised of different types of rooms using a partitioning system that is largely transparent as well.

Textile Skin

In order to facilitate natural ventilation, façade panels are operable. This has been made possible because the tower has been given a second skin, which eliminates possible inconvenience caused by the wind.

At the time of the preliminary design, the idea was that this outer facade would be made out of silk-screened glass, but during development the architect came up with the idea of a light-weight and consequently more cost-effective skin of Teflon-coated and open-weave fiber-glass textile.The soft turbulence behind the textile would neutralize the forces of the wind, so that the cavity between the textile and the thermal façade would be relatively tranquil and would enjoy a constant supply of fresh air. As a result, it would become possible to ventilate the offices directly with fresh air from the outside without any wind pressure problems. But there would also be another important advantage as the textile skin would also function as a sun shade without impeding the views.

Figure 4. New textile skin

The façade screen was inspired by textile applications in horticulture and is extremely light-weight in comparison to other outer façade solutions. At Westraven, the textile is attached to steel balusters by means of aluminum tubes, sharing the existing construction with the window-cleaning equipment.
Because such a solution has never been attempted before, the façade screen has comprehensively been tested against a large number of technical and functional criteria. These showed that the screen reduces the forces of wind and the sun adequately, but it is also sufficiently transparent and translucent. The colorfast fabric is unaffected by water, grease and dirt, is resistant to the weather, fungus, rust and insects, and is easily cleaned if necessary. Moreover, the screen does not flutter or vibrate and has been extensively tested to address the potential icing issues of the system.

The translucence and transparency can be attributed to a combination of factors; the difference between the light intensities inside and outside, the color and degree of reflection of the textile, and the angle of the sun all play a role. In addition, the distance of the textile to the building, the mesh-size, and the thread thickness of the fabric in relation to the resolution of the human eye are also relevant factors. Because the screen is so thin, good views remain possible across a very wide angle.

Both the Government Buildings Agency and the Department of Public Works went along with the textile skin, but opted for alternation of the fabric with strips of glass at eye level. Because the textile façade has no sound-insulating properties, the building has an outer façade of glass on the north side, which is closest to the motorway.

Mechanical Installations

To further improve the interior climate, all stories have been equipped with climate ceilings. Since the construction was erected using the jack-block system, it was designed to be as light as possible at the time. Therefore, the floors were relatively thin and had been reinforced with concrete beams. The spaces in between these beams were perfect for accommodating climate-control units suitable for both heating and cooling the building by pumping hot or cold water, respectively, through the pipes. For Westraven, the supplier customized the units so that several other components, such as the sprinkler system, intercom speakers and light fittings could also be integrated; thus contributing to a tidy, clear and visually unobstructed atmosphere.

Figure 5. Section through offices showing junction of tower and low rise structure and double skin façade

Podium

New low-rise sections have been added on either side of the tower. This added 24,000 square meters (258,334 square feet) of space to the existing 27,000 square meters (290,626 square feet) in the tower. These extensions have a V-shaped floor plan with rounded edges and are enclosed by a conservatory made of transparent material.

The sections are linked by an intermediate zone, with a large entrance area and two indoor gardens, while their hallways form an extension of the entrance. As a result, the ensemble, as a whole, appears as an indivisible unit in which the transition from old to new is hardly perceptible.
The structure of the extension is nearly all steel and has been dimensioned as slender as possible for both aesthetic and sustainability reasons: a slender construction of steel provides both lucidity to the building and reduces the use of material. Moreover, because of its relatively low weight and its excellent thermal conductivity, it absorbs and emits warmth faster than the more traditional and heavier concrete structure. As a result, less energy is being used for heating and cooling.

Sustainable Climate Concept

As mentioned, much attention has been devoted to obtaining perfect equilibrium between low energy consumption and an optimum working climate. For this purpose, a sustainable climate concept has been developed. The high degree of transparency of the design, for example, is not only based on architectural and aesthetical principles, but also by maximizing the use of daylight so less artificial lighting is needed. Also, a dynamic lighting system has been installed, which automatically adapts to the color and intensity of the natural light available.

Figure 6. Diagram of the building’s climate zones

Four different climate zones have been developed in order to adjust the climate concept to the actual day-to-day use of the building. The offices and workspaces are provided with full service climate control facilities. The floors of the new office wings have been rendered thermally active by means of a water network system that has been cast in the concrete slab components of the floors. Through this network, the structure is kept at a constant temperature. In the long term, this system uses less energy than an ongoing alternation of heating up and cooling down.

Since each of the conservatories is used for completely different functions (such as the restaurant, gatherings or workshops), the standards for these particular areas are less demanding. The bulk of these enormous spaces are heated by return air passing through the edge of the office floors.

At the ground level, this is complemented by floor heating. Since the conservatories serve as a buffer between the new office wings and the direct influences of the weather outside, the demands upon the office façades are relatively low. Therefore, an indoor partitioning system could be used for these, which saves considerably on construction costs. Perforated panels in the façades also contain sound insulation and can be opened, which allows for extra ventilation through the atrium.

During the warmer periods, an opening is created in the conservatories through a sun screen system for which the same fabric has been used as applied in the greenhouse industry. When the temperature rises, the screens automatically come down. The warmth is retained in the cavity between the screen and the façade and is naturally ventilated. The same technique is used in order to obtain the warmth entering through the transparent roofs between the office wings. An additional cooling installation is integrated into the floor.

Recognition

The Energy Performance Coefficient (EPC), which is a figure used in the Netherlands to measure the energy efficiency of a building, was 33% better than required by the Dutch Buildings Decree for the tower and even 50% better for the podium. Westraven has won the Daylight Award for its exquisite balance between the use of daylight, artificial lighting and other architectural aspects and was granted the Dutch Construction Award with much praise for its sustainability on all levels. Recently, Westraven has been shortlisted for the Prime Property Award 2010, which is a European prize for sustainable real estate investment.

The Westraven was recognized as the Best Tall Building Europe Finalist in the 2009 CTBUH Awards Program.

The new office building of The Korea Teachers Pension Head Office was established to bring the unification of three bodies for the stability and efficiency of educational pursuits: Teachers, The Korean Teachers Pension Head Office and the country.  Tomoon Architects and Engineershave designed this facility with these three organizations in mind to achieve this goal in Naju,.

The podium that acts as the entrance to the building is an extension of the urban axis that extends the urban context of Naju into the offices.  This move accentuates the visual recognition of the urban landmark as an intrinsic part of the city.  The building stands at the intersection of two axes, configured to the street that offers the greatest abundance of sunlight and ventilation.

The main entrance is placed through the open square in the east of the site, where the landscape is well harmonized with the water. The lower levels accommodate a promotion hall, customer service room, multi-functional all and sports facilities, in connection with the outdoor space known as the harmony court and Green Culture Slope in the south. The higher levels are vertically arranged to satisfy both independence and continuity of the business facilities based on security. The continuous volume of the lower levels is transformed in lines and sections within the tower and becomes a part of the Eco Smart Skin.

 based, Lebanese architect firm Hapsitus has presented us their work for the BLC Headquarter Landmark high rise design competition in . Follow after the break for more images of their winning proposal for this highly visible project.

BLC Bank  began a new departure in 2007 with a different administration, an impetus that gave rise to rapid growth and imposed the need for a new headquarters. The competition design brief required a building that would be a landmark in the urban texture of .

The presence of the existing building at the corner of the site was an enigma. It occupied a key corner position of the site, and was required by the client to be incorporated within a new design. With the ‘landmark’ concept as a driving force, Hapsitus proposed a solution created by the cantilevering of a new structure above the existing structure to make an urban gate addressing the city.

German architectural firm Pysall Ruge Architekten has designed the office building and health centre - LTD 1 located in Lübeckertordamm, Hamburg, Germany.

The office building’s configuration, composed of four boomerang-shaped elements laid over each other, creates a representative entrance situation, an interior courtyard, and a transitional space to the residential courtyard in the rear. As a result of this building form, every office has direct sunlight and an unobstructed view.

Peter Ruge Architekten

In the context of the revitalising of the St. Georg district of Hamburg, an urban plot of 120 dwelling units and an office building has been realised on a site next to Hamburg St. Georg hospital.The design extends the historic urban structure of the hospital to the housing units, and conceives the office building as a solitary form. The spatial composition of these buildings generates a green courtyard for the residential blocks, an urban place facing a new high-rise to the east, and a raised plaza on the west, as well as a semi-enclosed interior court in the new administrative building. The goal was to achieve appropriately differentiated urban spaces and building appearances, a high quality of life, protection from noise, and an optimal penetration of daylight in both the residential and office buildings. The green space in the interior of the block thus benefits the offices and the dwellings in equal measure.

The office building’s configuration, composed of four boomerang-shaped elements laid over each other, creates a representative entrance situation, an interior courtyard, and a transitional space to the residential courtyard in the rear. As a result of this building form, every office has direct sunlight and an unobstructed view.

The fully room-high façade elements alternate in a relief, staggered motif: a tilting and swing-opening door with a glass weather and sound protection panel in front of it, a highly insulated sandwich panel, and a sheet of fixed glazing. The asymmetric façade assembly, running vertically over the three storeys of one wing form in one direction, and in the opposite direction on the wing form above it, emphasises the building’s concept and provides an ever-changing show of reflected sunlight over the course of the day.

For the office building, ecologically unobjectionable materials are used throughout. The new building is a condensed form, and its surface area is optimised. Two service and sanitary cores lie inside and allow flexible use and simple adjustments to future requirements of the users. The building’s materials possess the “Blue Angel” certification and are thus ecologically friendly. An innovatively staggered, highly insulating external glass skin, a naturally ventilated double façade, low energy heating and concrete core cooling, as well as an energy-optimised lighting concept reduce the primary energy requirements.

The building has received the gold certification for sustainable architecture from the German Sustainable Building Council (DGNB).

The seal of approval of the DGNB is a system of certification created by the German Sustainable  Building  Council together with the Federal Ministry of Transport, Building and Urban Development. The rating system consists of 61 criteria which evaluate the whole life cycle of a building project with regard to sustainability.

The rating system goes far beyond the ecological standards of a simple ”green building”. With its spe-cific qualities it responds to all aspects of sustainable building: to its ecological, economic, functional and technical objectives, as well as demonstrating sustainability in the final execution process.

Hamburg – about to become the “European Green Capital 2011″ – now got the first office building with the highest seal of approval for sustainable architecture.
