Smarter Skin

2010-05-14T21:57:00.008-06:00

University of California engineer Luke Lee and architect Maria-Paz Gutierrez are developing an advanced “skin” for buildings that would regulate temperature and humidity through the physical properties of the materials used, dramatically reducing the need for electricity. Their project, called Self-Activated Building Envelope Regulation, or SABER, would regulate how much light and temperature enter and the building and how much humidity escapes by way of a membrane made of alternating rows of cells activated by light from the outside or humidity from the inside. Says Gutierrez, “the material has become the system.”

Inspired by compound eyes found on insects, Gutierrez and Lee’s SABER system is composed of light-sensitive cells composed of micro-lenses and pockets of photosensitive gel. The gel contracts in the light, opening up tubes that, in turn, allow more air to flow into the building in stronger light. The humidity regulation models itself on nature’s water-moving mechanisms. A polymer expands with increased moisture, opening up tiny tubes to increase airflow.

So far, only the lenses have made it to the prototype stage, Gutierrez told Inhabitat. Part of the project’s innovation will be working with companies to get the technology out the door and available.

A team of designers have crafted a futuristic reuse concept for Melbourne’s ill-fated Southern Star Observation Wheel, envisaging the wheel as a tram depot in the sky for “flying steam powered punk trams”.

Featuring wind turbine blades and solar panels, the sci-fi windmill would generate power for a fleet of flying trams, alleviating congestion in the city. The adventurous reuse proposal for the “heat-damaged and conceptually flawed” wheel, which closed 40 days after it opened in 2009 when cracks appeared in the frame, features landscaped platforms elevated above a newly-greened Docklands.

The detailed visualisations were created by architectural photographer Peter Bennetts, multi-disciplinary design form Büro North and film and media production studio Squint Opera. Soren from Büro North says: “There are some serious ideas and questions amongst the madness. How to efficiently adapt, reuse and re-function outdated infrastructure as we move to a more sustainable future.”

Unused shipping containers have for some time been recycled as shelter. Although this can be "green" and inexpensive, many have not been successful in their attempt at a responsible architectural solution.

AnL Studio (Minsoo Lee) has created this observatory as a precedent for the prevalent ongoing usage of shipping containers in rural South Korea.

Sinosteel - Tianjin, China [MAD]

2010-01-01T23:11:00.001-07:00

I recently came across the model from MAD which has a simple and artful facade. Construction is underway and is planned for completion in 2012.

From their website:

The varied honeycomb also improves the building's energy efficiency. Although the façade pattern appears random at first, it actually responds to the climatic conditions of the site. By mapping the different air-flows and solar direction across the site, and positioning the windows accordingly, it is possible to minimize heat loss in the winter and heat gain in the summer.

The skin is also structural, freeing up the interior from columns.

Director Park - Portland, Oregon [ZGF/OLIN]

Visiting Portland, Oregon, I was able to get a view of the nearly completed OLIN design for the south park block 5 in Portland, Oregon.

From the OLIN website:
With the redevelopment of an entire city block - a former parking lot - a significant urban plaza, built entirely over structure, will be introduced into the heart of Portland this fall. OLIN’s design creates new open spaces with a range of microclimates, amenities, and places for activity that will become a unique destination and landmark for residents and visitors. A key feature of Director Park will be an open, glass and wood canopy, accessible from the adjacent sidewalk and sitting high along the street’s edge, offering views over the plaza. The canopy will incorporate innovative stormwater techniques to capture and reuse runoff on-site to support the irrigation of plants during the dry months.

The design allows light into the park but provides shelter in the rainy Northwest.

The canopy - 25 ft tall, 40 ft wide, and 150 ft long - will drain its stormwater into raised planters, mostly by means of gutters concealed in the columns but also by "rain chains," which will make the storm drainage visible in a playful way.

The rain is harvested by flowing down the shed canopy into a stainless steel gutter. The rainwater flows from the gutter down cables and into a planter that provides a seating edge to the park.

Overflow from the planter flows out of the spouts shown above.

Some attractive new urbanist strategies are implemented which benefit the experience of the pedestrians and make the vehicular traffic secondary. No curbs exist, but ground texture mark spaces along with bollards and trees. The planters also take on stormwater. Street parking is only on the business side of the park street.

Granite stretches from one end of the block at the base of the Fox Tower to the base of the buildings to the west.

Manitoba Hydro Place - Winnipeg, Canada [KPMB]

2009-12-28T12:16:00.005-07:00

The new headquarters for Manitoba Hydro Place by KPMB architects is under construction. KPMB and Smith Carter and Transsolar have launched a great website that details the sustainable strategies used. The project used 100% fresh air year round in a very cold climate. It also utilizes a tall solar chimney seen in the above image, a double curtain wall facade, one of the largest geothermal systems in North America, special humidifying water features, green roof...and the list goes on.

I suggest reading more about the project on the KPMB website.
A 115 metre (377 foot) tall solar chimney marks the north elevation and main entrance on Portage Avenue, and establishes an iconic presence for Manitoba Hydro on the skyline. The solar chimney is a key element in the passive ventilation system which relies on the natural stack effect. The chimney draws used air out of the building during the shoulder seasons and summer months. In winter, exhaust air is drawn to the bottom of the solar chimney by fans, and heat recovered from this exhaust air is used to warm the parkade and to preheat the incoming cold air in the south atria.

Thin-film product uses cylindrical module

2009-12-24T06:00:00.000-07:00

One of the newer thin-film products out there is Solyndra. Currently they are not manufactured for vertical application, but I wonder if these could be on a facade?

From Solyndra:

Solyndra's panels employ cylindrical modules which capture sunlight across a 360-degree photovoltaic surface capable of converting direct, diffuse and reflected sunlight into electricity. Solyndra's panels perform optimally when mounted horizontally and packed closely together, thereby covering significantly more of the typically available roof area and producing more electricity per rooftop on an annual basis than a conventional panel installation. The result is significantly more solar electricity per rooftop per year.

Amazon Court, Prague [Schmidt Hammer Lassen]

2009-12-23T08:00:00.004-07:00

This building by Schmidt Hammer Lassen Architects has an intriguing light filled atrium. Daylighting played a major role throughout the design. The key design element being the central void appears to modestly open up to the green space.

From e-architect:

The atrium in Amazon Court is 32m across, seven-storey high and 2000m. in size – a highly distinctive court, involving an innovative intervention. The roof is designed using transparent lightweight material which, dispensing with heavy beams, is supported by slender rafters on the underside of ‘mullionless’ sheeting.

From the shl website:

Throughout the design process, there has been close collaboration with engineers in order to reduce the building’s energy consumption. Amazon court is predicted to have approx 50 % less energy consumption than a standard office and approx 65% less maintenance cost.

Gardens by the Bay, Singapore [Grant Associates]

2009-12-21T23:31:00.007-07:00

Designs have been released for Gardens by the Bay (official site here) a major landscape project for Singapore at 79 acres (32 hectacres) in size. Grant associates won the competition in September 2006.

The Supertrees are particularly interesting as they display tropical flowering climbers, epiphytes and ferns while collecting solar energy and water in their canopies. The video on the Grant Assoc. website diagrams these trees.

From Grant Associates:
The Supertrees are magical vertical gardens ranging from 25 metres to 50 metres in height. These structures are an iconic landmark for the Gardens and Singapore. They are also the environmental engines for the Conservatories and Energy Centre, containing solar hot water and photovoltaic collectors, rainwater harvesting devices and venting ducts.

Elisabeth & Helmuth Uhl Foundation - Laives, Italy [modostudio]

2009-12-20T10:15:00.011-07:00

Modostudio has won the competition for the Elisabeth & Helmuth Uhl Foundation (a private art & science organization) in northern Italy town of Laives.

The building blends well into the hillside and will reduce the amount of resources by utilizing the same footprint as the existing buildings. The demolished building material will also be used in the new construction, which would appear to be comprised primarily of stone. Modostudio writes that "an innovative photovoltaic + solar system will be experimented for the first time," which is not clearly seen in the renderings.

The building hugs the landscape and has a circulation spine running through it that connects the earth to the sky

New developments in translucent concrete

2009-12-19T12:34:00.010-07:00

LUCCON has created a translucent concrete product that is thermally insulated. This might allow the material to be used on facades to allow diffused daylighting into the building where an opaque material would be used otherwise.

From the LUCCON press release:
Translucent concrete can be considered one of the most beautiful, noble and mysterious product innovations in the last years. Translucent concrete cannot be described, one has to experience this mystical material in order to understand it.

LUCCON Lightconcrete is a combination of modern concrete and embedded fiber optic cables. Fiber upon fiber light is projected through the construction element – for example images beyond a wall appear pointwise or digitized on the opposite side, regardless if they are shadows, light, colors, projections or displays. The dimensions of the construction element are basically irrelevant with one exception:
With increasing thickness the experienced image on the hidden side appears increasingly peculiar and strange.

Digital Media City - Seoul, South Korea [SOM]

2009-12-17T19:43:00.018-07:00

Construction is underway on the Digital Media City tower by SOM. The tower will be the tallest in East Asia when completed in 2014. The tower utilizes several sustainable strategies. First, I would applaud it for being mixed-use and containing a hotel, offices, retail, and residential units. At 133 stories there should be space for all this program. The supertall tower takes advantage of the ability of the building form to create a stack effect.

The turbines at the top of the tower assist in reducing the energy load of the building along with the shading photovoltaic louvers on the facade. The "crown" also collects natural light, which is free. One inventive idea is the green outdoor observation deck (look right below the crown). This is supposed to naturally clean the make-up air that the building will take in. A clever idea, I am curiuos to how effective this really is. I count three wind turbines that look like they are more of a gesture than really effective...unless that spire is a stylized helical wind turbine?

There is even a little green roof at the base, wonderful.

Dochodo Island Zoo, South Korea [JDS Architects]

2009-12-16T18:53:00.015-07:00

JDS Architects, offshoot of PLOT, have designed portions of a Zoo on the South Korean Island of Dochodo. The architecture firm said the project is a "case study to define a tourist region based on sustainable development only, where natures and structures function in equilibrium, symbiotically feeding one another."

The main architectural feat being the aviary, which is rendered with exceptionally clear glass? It is difficult to understand from the images what the building would look like, it will be interesting to see how it is upon completion. If it is a conditioned space, it would have an enormous heating and cooling load.

Its an exciting looking piece of geometry, reminiscent of the "Bird's Nest" by Herzog & de Meuron (are they still the only architecture group without a website?), but rather more organized structurally. It is a pretty image, but I am not sure if this will be a good piece of architecture once the details are finalized, or if it will achieve the sustainability it boasts.

See the story on Inhabitat:
"According to JDS, the zoo’s landscape of natural peaks and valleys is ideal for zoo development. The flat valleys could host animals, while more mountainous areas could be protected and treated as nature reserves. All transportation, energy sources and building systems would be housed in a so-called “infrastructural green belt” located at a height of 20 meters. Everything above and below would remain untouched.

The proposed zoo would be as low-impact as possible, with zero-carbon transport systems, renewable energy sources, rainwater collection sites, and all waste would be reused as either composted fertilizer or biofuel. Dochodo sounds like an ideal location for a low-impact zoo, but we have to wonder about the potential impact of tourists constantly shuttling from other cities to the island. To the architects’ credit, they did notify us that the island will be accessible by bridge, which is much better than having a location that is only reachable by plane."

Just recently, with the success of the wind turbine industry, T. Bailey inc., has decided to make an upgrade to their offices. Designed by the firm Olson Sundberg Kundig Allen (soon to be renamed Olson Kundig). It is an intersting take on the wind turbine as visitors will enter through the giant steel tube shapes used in the wind turbines support. It is interesting that there is no wind power used (there is likely low winds, possibly not a good display for clients), but solar energy powers a fan at the top of the vertical tube that ventilates the office.
Overall, I would say this is a good combination of passive and active strategies, and I like the usage of the wind turbine supports in a creative way.
The design did recieve an AIA honor award
