CLOSED

The closure of Washington Avenue has moved all public and campus transit stops from Washington Avenue to Pleasant and University Avenue. Church Street will not function as a major north-south pedestrian connector until Washington Avenue reopens in 2014. This presents an opportunity to radically redesign and restructure Church Street.

exterior perspective at pedestrian mall

New exterior features include designated table seating, pervious paving, street trees, prairie landscape, integrated planters, and bicycle parking. An “active light wall” marks the main entry to the addition, incorporating the electrostatic friction technology employed by the van der Graaf generator to produce small low-voltage sparks in a double-glazed facade.

design proposal

interior perspective at addition

The addition provides a casual interior gathering zone that showcases the building’s new sustainable features, such as a living machine, rainwater storage bladders, biowall, and solar-heated thermacline. Adjacent renovated areas house a cafe, specialty bookstore, and public lecture room.

+ Upon completion of a water-pressurizationsystem, the treated wastewater is recycledback through the building for non-potablere-use.

+ Treats wastewater using asystem of engineered ecologiesthat include microbes, plants,snails and insects, and isdesigned to treat up to 2,000gallons of the building’swastewater daily in a beautiful,garden-like atmosphere.

case study absorption cooling

http://www.scribd.com/doc/39704858/TROX-Chilled-Beam-Design-Guide

+ The energy benefits by using water as a medium can in this way be fully utilised. In new buildings they offer low investment costs and high cooling capacity, and they are also the preferred option in retro-fit installations.

+ The heat is absorbed lifting the chilled water temperature and is removed from the space via the return water circuit. About 85% of the heat removal is by convective means, therefore the radiant cooling contribution of passive chilled beams is minimal and typically ignored.

- The ceiling area is limited as other services limit the degree of employment of the active ceiling surface such that their maximum space sensible cooling capacity is very typically less than 25 BTU per square foot of floor area.
