Carbon Footprint Issue

The world is in a constant state of flux and the environment is no different. Lately, it seems as though flash flooding, earthquakes, and hurricanes are occurring all too often.

The severity of them is seemingly unprecedented. Additionally, cities like Washington, D.C. – normally accustomed to mild winters – are experiencing record snow fall while those that expect heavy precipitation, like Syracuse, NY, are setting records for not having any of it. While this may or may not have anything to do with global warming, it certainly is a reminder that the environment is capable of a lot of unexpected changes and we should be doing what we can to balance our use of natural resources and minimize our carbon footprint. Otherwise, the odd, eyebrow-raising nature of weather patterns we’re currently experiencing may end up being catastrophic events down the road.

Proposed Solution – You Can Be A Part Of It

Yet, what can be done that isn’t currently being done? Cutting down on carbon emissions and recycling have been at the forefronts of the go green movement. However, some initiatives that target a completely new, green infrastructure have gone unnoticed but are essential to competitiveness, long term sustainability, job growth, energy independence and national security.

According to the Department of Energy, heating and cooling account for 50 to 70% of the energy used in the average American home. A large proportion of energy is lost through cracks in walls and ceilings. In terms of energy conservation, individuals can make immediate improvements to their energy profile simply by adding insulation to their home. Arguably, the best insulation for any green home is Cellulose which, according to the U.S. Green Building Council, requires less energy to make and is made of 75% recycled material. This is great for air quality in the home and also for the environment. There’s also renewable Cotton, abundant Fiberglass, and even Soy based foam insulation, which has the highest percentage of renewable resource ingredients in the industry with 60%. By doing this, any homeowner can add value to their home while conserving energy and reducing their utility bill. Long term savings outweigh upfront costs. The implementation of Smart Meters can help them find other areas of their home where energy can be used more efficiently. In some locations, local governments are providing residents with them for free. This seems to be the best strategy for getting residents the tools necessary to cut energy costs. The theory suggests that consumers will make necessary changes to their energy consumption if they can actually see exactly where it is being used inefficiently.

Aside from individual efforts, there are a lot of groups and organizations that people can get involved with that tackle larger projects. The University-National Park Energy Partnership Program (UNPEPP) is a great example. UNPEPP is a public private partnership (PPP) that puts federal grant money in the hands of young, impressionable university students eager to change the United States landscape one national park at a time. Universities all across America use the federal grant money to create internship opportunities for students to travel to a national park in their area and work with energy and environmental professors, experts and park personnel to perform energy audits, recommend energy conservation measures and implement renewable energy technology (RET) that ultimately save the parks thousands in energy costs and significantly reduce their carbon footprint. The UNPEPP 10 year Report is posted on the website. This type of partnership is a rewarding experience for everyone involved and similar PPPs should be on the forefront of the green energy movement.

A third component of building the green energy infrastructure involves business owners. While individual efforts generally result in relatively smaller improvements and PPPs sometimes get delayed by energy policies hung up by the legislative process, private businesses march to the beat of their own drum. They are in a position to tackle large scale projects that can create a large impact without delay. A lot of businesses see the potential for going green. Many of them have come on board. There is actually a scoring system that was devised in 1998, called LEED Certification to help gauge just how far a company has gone to incorporate green initiatives into their designs. Specifically, the Leadership in Energy and Environmental Design (LEED) Green Building Rating System provides a benchmark for the environmentally sustainable creation and use of buildings and neighborhoods. According to USGBC, 72% of electricity consumption and 39% of energy use come from buildings in the United States alone. LEED certified buildings use efficient resources to improve performance with energy conservation, CO2 emissions reduction, and water efficiency all while enchaining the ecosystems they are a part of – rather than diminishing them.

Initiatives – Green Design

One major company, Globetrotters Engineering Corporation (GEC), an architectural company founded by engineer and CEO, Niranjan Shah, is an example of a company that adheres to LEED certification. GEC is responsible for the management of many facets of modernization and expansion of O’Hare International Airport in Chicago (the first privately managed terminal in the United States). Niranjan Shah proved that implementation of green design can be successful, helpful to society and profitable all at the same time. An example of another company that earned LEED Certification is the Washington D.C. based mortgage company, Fannie Mae, which was responsible for the first-ever LEED data center. There are countless other companies that are earning LEED certification. Government incentives given to companies that earn LEED certification is a way to boost the number of participants and achieve the environmental sustainability results that environmentally friendly federal energy policies target but can’t necessarily get passed through legislation.

On a much larger scale, organizations like the Clinton Global Initiative (CGI), founded by Bill Clinton and counselor Doug Band are doing their part to bring the strongest political leaders together to tackle world problems.  However, small projects at home, public private partnerships and LEED certification are methods that combine to allow everyone a chance to get involved to curtail inefficient energy use. The necessity to highlight them cannot be understated. The planet is home to all of us and the best way to ensure sustainability is to live and work as environmentally friendly as possible.

Do you agree that the current situation is not what we can call pink? What do you think can be done by individuals?

World renowned architect Daniel Libeskind has announced that on September 29, he will unveil the prototype for his highly anticipated Libeskind Villa. The Libeskind Villa is a German-made, sculptural living space which marries the highest standards in design, craftsmanship and sustainability. The project has been realized in partnership with Berlin based proportion GmbH and the prototype has been built on the premises of Rheinzink GmbH & Co., the developer of the Villa’s zinc façade. More info and images after the break.

The Design
The Libeskind Villa, Daniel Libeskind’s first signature series home, creates a new dialogue between contemporary living and a completely new experience of space. It is unique at every turn, offering maximum insulation and durability, cutting-edge technologies and compliance with some of the toughest energy-saving standards across the world. The Libeskind Villa awakens the senses: light floods through glass expanses, clean lines invite calm, elegant halls and staircases offer seamless transitions. Symbolically and physically, the Villa’s connection with nature is uninterrupted, offering ample natural light and open spaces.

A trio of interlocking architectural bands envelops the Villa in striking angles, creating a dramatic, asymmetrical interior of spiraling, two-story peaks and smooth transitions to secluded terraces. The impressive entrance hall leads to an elaborate Grand Room which highlights the geometric space. Design details reveal style and functionality: A balcony adjacent to the master bedroom is adorned with elaborate metalwork; light wells direct daylight into a sauna; and recessed wardrobes streamline dressing spaces.

Sustainable Materials
Sustainable materials are at the heart of Libeskind’s design. While not apparent from the exterior, the Villa is largely constructed of wood, a renewable resource that is making a strong comeback as a key building material for the 21st Century, due to its impressive carbon-storing capabilities.

The wooden core offers maximum thermal insulation, and thus efficient operation. With more than 360 mm of recyclable wooden fibers and a heat transition coefficient of 0.11 W/m²K, the insulation of the Villa’s exterior walls matches that of passive houses.

Renewable Energy Sources
The Villa employs onsite renewable energy sources for heating, electricity and water. Its standard configuration includes a solar thermal system which is invisibly integrated into the zinc façade, as well as a geothermal system with a high-efficiency heat pump. In addition, electric power may be generated from photovoltaic thin film, while rain water can be harvested from the rooftop for use in the garden’s irrigation system.

Energy Saving Standards

As a result of its high thermal insulation capabilities and renewable energy sources, the Villa is classified as a low-energy structure. Indeed, it complies with some of the world’s toughest energy-saving standards, such as Germany’s KfW40 code, which indicates a thermal energy consumption of less than 40 kWh/m²a.

The skylines of the world´s most important cities (except for Dubai I guess) are shaped by the typical office tower. The reason is simple: it provides a flexible floor plan, with an economical structural system. “Bang for the buck” if you want to call it. To address lighting and cooling issues that these tower traditionally have, electric lighting and air conditioning were the solution.

But in times when energy is a big issue, we can no longer design buildings that depend on high consumption to provide a comfortable working environment, specially in tropical weathers. And this is what BIG had as a design principle for the Shenzhen International Energy Mansion competition they just won, proposing a tower based on an efficient and well-proven floor plan, enclosed in a skin specifically modified and optimized for the local climate.

Exterior render

We propose to enhance the sustainable performance of the building drastically by only focusing on its envelope, the façade.

We propose to make the Shenzhen Energy Mansion the first specimen of a new species of office buildings that exploit the buildings interface with the external elements – sun, daylight, air humidity, wind – as a source to create a maximum comfort and quality inside.

The Shenzhen Energy Mansion will appear as a subtle mutation of the classic skyscraper – a natural evolution rather than a desperate revolution.

More details on how this facade works, along with more information after the break:

Facade diagram 1

1.The traditional curtain wall glass façade has a low insulation level and leaves the offices overheated by the direct sunlight. This results in excessive energy consumption for air conditioning as well as the need for heavy glass coating that makes the view seem permanently dull and grey.

Facade diagram 3

2.By folding the façade in an origami like structure we achieve a structure with closed and open parts. The closed parts are providing a high-insulation façade, while blocking the direct sunlight. On the outside the closed parts are fitted with solar thermal heat panels that are powering the air conditioning and providing dehumidification for the working spaces.

Facade diagram 2

3.The folded wall provides a free view through clear glass in one direction, and creates condition of plenty of diffused daylight by reflecting the direct sun between the interior panels.

Facade diagram 4

4.Even when the sun comes directly from east or west, the main part of the solar rays are reflected off the glass due to the flat angle on the window. The reflected rays increase the efficiency of the solar thermal energy panels. The combination of minimal passive solar heating as well as active solar panels will reduce the building energy consumption with more than 60%.
