905 Innovative Practices – Above Green

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.

Required Documentation

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.

Required Documentation

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)

Required Documentation

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.

Required Documentation

Confirm on building plans and check manufacturer literature to confirm lamp enclosure is NEMA-rated.
