    (a) Mixed-Fuel Buildings of Hotel, Motels or High-Rise Multifamily Occupancies
    1. Install fenestration with a solar heat gain coefficient no greater than 0.22.
    2. Design Variable Air Volume (VAV) box minimum airflows to be equal to the zone ventilation minimums.
    3. Include economizers and staged fan control in air handlers with a mechanical cooling capacity 33,000 Btu/h.
    4. Reduce the lighting power density (Watts/ft2) by ten percent (10%) from that required from Table 140.6-C.
    5. In common areas, improve lighting without claiming any Power Adjustment Factor credits:
    A. Control to daylight dimming plus off per Section 140.6(a)2H, and
    B. Perform Institutional Tuning per Section 140.6(a)2J
    6. Install one drain water heat recovery device per every three guest rooms that is field verified as specified in the Reference Appendix RA3.6.9.
    (b) All Other Nonresidential Mixed-Fuel Buildings
    1. Install fenestration with a solar heat gain coefficient no greater than 0.22.
    2. Limit the fenestration area on east-facing and west-facing walls to one-half of the average amount of north-facing and south-facing fenestration.
    3. Design Variable Air Volume (VAV) box minimum airflows to be equal to the zone ventilation minimums where VAV systems are installed.
    4. Include economizers and staged fan control in air handlers with a mechanical cooling capacity 33,000 Btu/h.
    5. Reduce the lighting power density (Watts/ft2) by ten percent (10%) from that required from Table 140.6-C.
    6. Improve lighting without claiming any Power Adjustment Factor credits:
    A. Perform Institutional Tuning per Section 140.6(a)2J, and
    B. In office spaces, control to daylight dimming plus off per Section 140.6(a)2H, and
    C. Install Occupant Sensing Controls in Large Open Plan Offices per Section 140.6(a)2I.
