Common use of Mechanical System Clause in Contracts

Mechanical System. a. The following criteria shall govern for the design of mechanical systems in remodeled buildings and in new buildings regardless of whether or not the features are required to meet the Design Energy Budget: (1) Except where potential funding sources may be put at risk due to higher ventilation rate requirements, it is recommended that one (1) CFM of air be exhausted from each square foot of laboratory floor area. This does not preclude higher rates necessary to offset exhausts from equipment located within the laboratory, or higher rates necessary to maintain acceptable space temperature. A laboratory is defined as a workspace where chemicals are used and/or stored. (2) The number of air handling units in a building shall be as few as feasible to serve the building. Each system shall be provided with a return air fan or relief fan to discharge air to the outside in direct ratio to the outside air being introduced into the system. The system shall be capable of exhausting 100% of the building return air when the system is on a controlled ventilation cycle. (3) On projects where generation of steam or chilled water for heating and cooling is part of the design of the building, provide life-cycle cost analysis to determine the most economical primary fuel to use, with consideration given for the anticipated availability of fuel during the life expectancy of the generating equipment. (4) All new and remodeled building projects shall conform to ASHRAE Standard 90.1. (5) The mechanical systems within the building shall be designed in accordance with this section and sections of the Design Guidelines unless more stringent requirements are indicated in the standards of the State Energy Conservation Office. (6) All projects utilizing campus chilled water, heating hot water, and/or steam shall be specified to have BTU meters, or flow meters and supply and return temperature sensors, depending on campus preference.
