905.1 - Humidity Monitoring System (2 points)
A humidity monitoring system is installed with a mobile base unit that displays readings of temperature and relative humidity. The system has a minimum of two remote sensor units. One remote sensor unit is placed permanently inside the conditioned space in a central location, excluding attachment to exterior walls, and another remote sensor unit is placed permanently outside of the conditioned space.
905.2 - Kitchen Exhaust (2 points)
A kitchen exhaust unit(s) that equals or exceeds 400 cfm (189 L/s) is installed, and makeup air is provided.
Manufacturer’s literature showing cfm.
905.3 - Enhanced Air Filtration (2 points)
Meet all of the following:
Design for and install a secondary filter rack space for activated carbon filters.
Provide the manufacturer’s recommended filter maintenance schedule to the homeowner or building manager.
Review plans for location of secondary filter rack.
905.4 - Sound Barrier (1 SF / 4 MF)
Provide room-to-room privacy between bedrooms and adjacent living spaces within dwelling units or homes by achieving an articulation index (AI) between 0 and 0.15 per the criteria below.
Articulation Index 0 to 0.05 = STC greater than 55 (NIC greater than 47)
Articulation Index 0.05 to 0.15 = STC 52 to 55 (NIC 44 to 47)
Building plans should confirm the intent to have a sound barrier that meets the criteria above.
905.6 - Evaporative Coil Mold Prevention (2 points)
For buildings with a mechanical system for cooling, ultraviolet lamps are installed on the cooling coils and drain pans of the mechanical system supplies. Lamps produce ultraviolet radiation at a wavelength of 254 nm so as not to generate ozone. Lamps have ballasts housed in a NEMA-rated enclosure.
Confirm on building plans and check manufacturer literature to confirm lamp enclosure is NEMA-rated.
