Creating “living buildings” requires a new approach to design and construction that recognizes the need to reduce our energy footprint. With this in mind the designers of  the Bullitt Center, a 6-storey headquarters for the Bullitt Foundation, intend to create a sustainable office building that minimizes its environmental footprint.

The new building being constructed in downtown Seattle, and opening in late 2012, uses 1/3 of the energy normally consumed by a standard office building of equal size. The building generates its own electricity using solar arrays, collects rainwater for internal consumption, and treats sewage and wastewater on site. Although still connected to the electrical grid the building systems send power back to the grid when producing beyond the needs of its tenants resulting in net zero electricity usage from utilities.

India’s Navigational Satellite On The Card

 First Indian navigation satellite will be launched this year, announced President Pratibha Patil, during the joint sitting of Parliament. The Indian Regional Navigation Satellite System (IRNSS) will be a constellation of seven satellites having all-weather, round-the-clock coverage over the Indian landmass with an extended coverage of about 1,500 km around it.
“Several major satellite launches are planned for 2012, including India’s first microwave remote sensing satellite (RISAT-1) with all-weather imaging capability,” President added. She said that the next flight of the Geosynchronous Satellite Launch Vehicle using the indigenous cryogenic upper stage was also proposed to be conducted this year.
Besides use in the agriculture sector, the all weather capability of RISAT-1 could also be used to keep an eye on the country’s borders round-the-clock and help in anti-terrorist and anti-infiltration operations.
The IRNSS, which will have a range of applications including personal navigation, will be India’s answer to the US-operated GPS, Russia’s Glonass, European Space Agency’s under-development Galileo, and China’s emerging constellation, Compass.
