NOISE LEVELS Noise levels inside occupied spaces generated by HVAC systems indoors shall not exceed NC 35. INTERNAL Occupancy: Use ASHRAE standards to calculate sensible and latent heat from people. In general, light/moderate office work is 73watts sensible and 45watts latent. Lighting: Provide 21.5 W/m2 maximum (however lighting levels meet minimum requirements and shall be accounted for in the heating and cooling loads based on the actual lighting design). Ventilation: provide outdoor air ventilation per ASHRAE Standard 62.1 with the exception of guard towers, guard shacks, and storage facilities. In general this requires 2.5 L/s/Person and 0.3 L/s per square meter of floor space; outdoor air requirements can be satisfied by opening windows and doors for facilities without a ducted system. Latrine/Bathroom Exhaust: Provide 85 CMH per toilet, urinal, or shower head. Building Pressurization: Provide 1.3 mm W.G. (0.05 in W.G.); Maintain negative pressure in latrine areas. This is only applicable for buildings provided with central ducted forced air systems NEW AIR COOLING & HEATING EQUIPMENT Environmental control of the facilities be achieved by HVAC equipment as listed below and approved by the U.S. Government. Unless otherwise noted, the Contractor may choose any combination of equipment to achieve the inside design conditions specified for the floor plans that is the most Life Cycle Cost Effective to the government. Contractor shall size and select equipment based on equipment manufacturer’s performance data at the project site elevation and ensures the equipment’s performance meets the design heating and cooling sizing requirements.
