Plaza del Rio
Southwest Corner of Friant and Fresno St. (Off of Freeway 41), Fresno
The design of this 65,750-square-foot, three-story office building in north Fresno focused on providing superior tenant comfort with the lowest possible energy costs while maintaining competitive construction costs.
Four different HVAC systems were analyzed before making a final selection. Several factors were considered: construction costs, anticipated energy costs, maintenance costs, water consumption, impact on other trades and impact on architectural features. The best solution was determined to be a rooftop variable volume system using a separate unit for each floor with two compressors in each unit.
This system allows the largest number of leasable square feet because the air conditioning units are on the roof. Another advantage is the fact that no tenants are disturbed during service and repair of the rooftop units. This type of system, working with a building management system, allows an unlimited number of zones to satisfy unknown tenant requirements.
Although constructed in 1994, it was awarded the EPA Energy Star rating in 2003. The rating is an acknowledgement that this office building is among the top twenty-five percent in the United States for energy conservation.
