Overview   ..............................................................................................................

Given the particular configuration of the existing buildings on the Tempe site, we propose to take advantage of the opportunity to activate both sides of the larger structure. The new passageways encourage customers to move through the building as well as around it. With more exposure and storefront space between tenants, a mutual beneficial relationship develops between the tenants.

We also propose a re-programming of certain areas of the parking lot for weekend and evening events. The parking is also spread around the entire building allowing for all sides of the building to have frontage. A lightweight steel frame and fabric roof system will be deployed to ameliorate the parking, landscaped areas and buildings. This roof system will operate on various levels to improve the quality of the spaces, increase the mechanical efficiency and reduce energy consumption for the tenants and customers. First, it creates a shaded parking environment, which helps to reduce the heat island effect of asphalt as well as extends the viable time outdoor space may be used in the Southern Arizona climate. Second, it creates a solar barrier, providing shade over the existing buildings.

This second layer allows for the development of convection currents between the existing roofs and new shade layer. These currents help to reduce the solar heat gain on the existing buildings and improve the efficiency of mechanical systems. The roof will also be integrated with a series of roof ponds 12” deep that are strategically located throughout the project. The cool water stored in roof ponds act as “thermal sponges” conducting heat through the ceiling supporting them. The new roof has insulated panels which reflect the sun away from the pools in the daytime cooling cycle. At night, the panels are raised up, exposing the water to the cool night sky and breezes. The ponds lose heat by radiation to the night sky and convection through breezes. To further improve their effectiveness, the roof ponds link to hydronic trombe walls. Natural convection circulates cool water down from the roof ponds into the lower levels of the space and help to remove heat This system reduces the need for traditional air conditioning and saves energy.
