The new Household Materials Collection and Training Center will serve the needs of many city residents with it's bi-parti building program. Located in a former animal incinerator facility, the structure incorporates a green vegetative screen and roof systems, a solar wall for heating the training facility, the maximization of natural daylighting through skylights and sensors, as well as the reuse of existing insulated metal panels removed from the building. The first or Southern half of the building will include a workforce Training Center to teach ex-offenders practical job skills. This half of the building regularly occupied spaces include a classroom, offices, and a training floor. For these spaces, operable windows and lighting controls servicing the perimeter areas of the rooms have been specified in attempts to meet or exceed the EQc6.1 and EQc8.1 requirements. The training room will utilize the group multi-occupant spaces definition as noted in CIR 0098-EQc6.1-120904 for LEED-NC v2.1 projects. In addition, existing skylights will be utilized to increase the natural daylight exposed to the interior of the building. The second or Northern half of the building includes the Household Materials Recycling Facility, which will give city residents a place to properly dispose of their household hazardous waste: paint, batteries, oil, pesticides, etc. In addition, cell phones, computers, etc. will be accepted for recycling. This portion of the project consists of three spaces - an outdoor yard for hazardous waste storage enclosures, as well as two indoors spaces - Collection/Process area and a materials storage Warehouse area. The Warehouse area, separated from the Collections area by a four hour fire wall, will be used mainly to store bundled materials prior to shipping and is not open to the public. The Collections/Processing area will be typically open to the public one day and two afternoons (equivalent of 2 full time days) a week. During the hours the Collections/Processing area will be open to the public, the two sets of double doors and two industrial garage doors will be opened to the exterior, signaling the facility's "open" status. These openings will allow access to the Collections/Processing area for the public to drop off of materials, as well as allowing employees to move materials around and out of the Collections/Processing area and to the exterior. The doors are to be open at all times of year in all weather conditions, when the facility is open and running. Due to the rough nature of the facility and the fire resistive requirements by building code for this hazardous portion of the building, windows are prohibited in the Collections/Processing area. Overhead lighting for this area will be controlled by wall mounted switches under a 200 sqft average coverage zone. Request: Interpretation of LEED 2.1 NC Credit IEQ 6.1 pertaining to "regularly occupied space" is requested here. Although an industrial (also possibly hazardous) building has been interpreted in CIR IEQc8.1-092403, should it be interpreted in a similar method for IEQc6.1 calculations? CIR 0098-EQc6.1-110901 does suggest some degree of interpretation for areas deemed regularly occupied, but it is not specific enough for our building type/use. We believe that in this case, the regular operation of large, overhead doors as a source for natural light and ventilation is an acceptable substitution for windows. However, our exact situation is presently beyond the scope of current definitions and interpretations. Please confirm if our situation will fulfill the requirements of this credit.
If documentation of official operations policy is provided stating the following, the Collections/Processing area may be excluded from the "regularly occupied spaces": 1. The Collections/Processing area will indeed be open to the public only for one day and two afternoons a week AND 2. None of the employees will be "stationed" in this space; apart from visits to move materials around and out of the Collections/Processing area.
