Our project consists of the construction of a mixed-use building, predominantly residential to be located in a downtown area. There is a tower portion of the building, which is flanked on the south and east sides by mid-rise townhome suites. Five levels of underground parking will be located beneath the tower, with a typical floor area of about 34,500 ft2. The intent of this credit is to provide a high level of lighting system control, in both individual levels, and in multi-occupant spaces. Specifically, the requirements are to provide controls for 90% of occupants for individual tasks, and controllability for shared multi-occupant spaces. As the majority of the building is of a residential nature, we propose the following definitions for equivalency. Regularly occupied spaces would be deemed as living rooms or dining rooms, and would be equipped with switches and dimming. Workstations would be deemed as kitchens and bathrooms, and would be equipped with switches, dimming, and point lighting for tasks. Non-regularly occupied spaces would be deemed as bedrooms and hallways, with switching only. With these designations, would our lighting control design would satisfy the requirements of the credit?
*NOTE* 10/13/2007: The EQ TAG has revised the definition of "regularly occupied space" in residential applications. The definition to be amended in the LEED-NC reference guide is as follows: REGULARLY OCCUPIED SPACES --- Areas where workers are seated or standing as they work inside a building; in residential applications it refers to all spaces except closets or other storage areas, utility rooms, and bathrooms. (Bedrooms, living rooms, TV rooms, dining rooms, kitchens, media rooms, etc. would all be considered "regularly occupied" in residential applications.) --- Original ruling: Based on the residential nature of the project, the room designations, as described, would not satisfy the credit requirements. In residential type projects, regularly occupied spaces would most likely include bedrooms, living rooms, dining rooms, offices/study, den, etc. Non-regularly occupied spaces would include, bathrooms, storage, laundry room, kitchens and equipment rooms, etc. Depending on the size of the space, dining and living rooms could be defined as a multi-occupant space, while the other spaces, i.e. bedrooms, offices, could be considered an individual type space. To support credit compliance, a description of the individual spaces and their respective functions would need to accompany the calculations and LEED Submittal Template.
