New fuel fired equipment utilizing the more efficient performance option of <br />Section C405.14 shall comply with the more efficient HVAC equipment <br />performance of Sections C406.2, C406.2.3, and C406.2.4. A mechanical <br />compliance certificate demonstrating compliance with section C406.2.3 and/or <br />C406.2.4 shall be required for all HVAC and Service Water Heating equipment. <br />The efficiency shall be verified through certification under an approved <br />certification program or, where a certification program does not exist, the <br />equipment efficiency ratings shall be supported by data furnished by the <br />manufacturer. Where multiple rating conditions or performance requirements are <br />provided, the equipment shall satisfy all stated requirements. Where components, <br />such as indoor or outdoor coils, from different manufacturers are used, <br />calculations and supporting data shall be furnished by the designer that <br />demonstrates that the combined efficiency of the specified components meets the <br />requirements herein. <br />14. Section C403.4.1 Thermostatic controls, is hereby deleted and replaced in its <br />entirety and the following is hereby added in lieu thereof: <br />C403.4.1 Thermostatic controls. The supply of heating and cooling energy to <br />each zone shall be controlled by individual thermostatic controls capable of <br />responding to temperature within the zone. Where humidification or <br />dehumidification or both is provided, no fewer than one humidity control device <br />shall be provided for each humidity control system. Occupancy sensors shall be <br />provided on the thermostat to setback in accordance with C403.4.2.1 <br />Exception: Independent perimeter systems that are designed to offset only building <br />envelope heat losses, gains or both serving one or more perimeter zones also served <br />by an interior system provided that both of the following conditions are met: <br />1. The perimeter system includes not fewer than one thermostatic <br />control zone for each building exposure having exterior walls facing <br />only one orientation (within ±45 degrees) (0.8 rad) for more than 50 <br />contiguous feet (15 240 mm). <br />2. The perimeter system heating and cooling supply is controlled by <br />thermostats located within the zones served by the system. <br />15. Section C403.12.1 Duct and plenum insulation and sealing, is hereby deleted and <br />replaced in its entirety and the following is hereby added in lieu thereof: <br />C403.12.1 Duct and plenum insulation and sealing. All supply and return <br />air ducts and plenums shall be insulated with not less than R-12. Ducts, air <br />handlers and filter boxes shall be sealed. Joints and seams shall comply with <br />Section 603.9 of the International Mechanical Code. <br />7 <br />
