KING OF PRUSSIA, Pa.
The two-building First Avenue Corporate Center is being developed by Dallas-based Prentiss Properties to include many "green" features. Each 103,000-sf building will have sun-deflecting, energy-efficient glass; an air-conditioning system that brings fresh air into the facility as carbon dioxide levels rise, as well as "flushing" the building each night with fresh air. Recycled steel will be used in construction, and carpets and wallpaper will be made from recycled materials. Construction has already begun on the first building.
