Cross Cutting Issues EXAMPLES OF SPACES THAT ARE TYPICALLY - PDF document

1/6/2017 Cross – Cutting Issues • EXAMPLES OF SPACES THAT ARE TYPICALLY UNOCCUPIED: • Mechanical and Electrical Rooms • Egress stairway or dedicated emergency exit corridor • Closets in residence (walk in closet is occupied) • Data center floor area, including raised floor area • Inactive storage area in a warehouse or distribution center • For areas of equipment retrieval, the space is unoccupied only if the retrieval is occasional. Cross – Cutting Issues • REGULARLY VERSUS NONREGULARLY OCCUPIED SPACES • Based on duration of the occupancy. • Regularly occupied spaces are enclosed areas where people normally spend time, defined as more than one hour of continuous occupancy per person per day, on average; the occupants may be seated or standing as they work, study, or perform other activities. • For spaces that are not used daily, the classification should be based on the time a typical occupant spends in the space when it is use. i.e. Computer Workstation • Non regularly occupied spaces are areas people pass through or areas used an average of less than one hour per person per day. Cross – Cutting Issues FLOOR AREA CALCULATIONS AND FLOOR PLANS • For many credits, compliance is based on the percentage of floor area that meets the credit • requirements In general, floor area and space categorization should be consistent across the EQ credits. • Any excluded spaces or discrepancies in floor area values should be explained and • highlighted in the documentation. SPACE CATEGORIZATION • EQ Category focuses on interaction between the occupants of the building and the indoor • spaces in which they spend their time. It is important to identify which spaces are used by the occupants, including visitors • (transients) and what activities are performed in each space. Depending on the space categorization, the credit requirements may or may not apply. • OCCUPIED VERSUS UNOCCUPIED SPACE • All spaces must be categorized as either occupied or unoccupied. • Occupied spaces are enclosed areas intended for human activities. • Unoccupied spaces are places intended primarily for other purposes; they are occupied • only occasionally and for short periods of time – inactive areas. 1

1/6/2017 Option 2 Requirements Choose four of the following strategies. Option 1 Requirements Lighting control must enable occupants to adjust lighting lighting to 3 different levels (on, off, midlevel) -Midlevel between 30-70% 22

1/6/2017 Option 2 Requirements Option 2 Requirements A. For all regularly occupied spaces D. Use direct-only overhead lighting use light fixtures with a luminance of for 25% or less of the total connected less than 2,500 cd/m 2 between 45 and lighting load for all regularly 90 degrees from nadir occupied spaces. Option 2 Requirements Option 2 Requirements E. For at least 90% of the regularly occupied floor area, meet or exceed the B. Use light sources with CRI of 80 following thresholds for area-weighted average surface reflectance: 85% for or higher ceilings, 60% for walls, and 25% for floors Option 2 Requirements Option 2 Requirements F. Select furniture finishes to meet or C. For at least 75% lighting, use exceed the following thresholds for light sources that have rated life of area-weighted average surface reflectance: 45% for work surfaces, at least 24,000 hours and 50% for movable partitions 23

1/6/2017 Option 2 Requirements G. For 75% of regularly occupied space, meet a ratio of average wall surface illuminance to average work plane illuminance that does not exceed 1:10. Option 2 Requirements H. For 75% of regularly occupied space, meet a ratio of average ceilling illuminance to work surface illuminance that does not exceed 1:10. 24
