Spaces with glazing above 10 feet in height may have difficulty getting sensors placed within 15 feet of the windows to function properly because of increased glare and
It makes sense to pursue this credit in open office applications with few interior partitions and access to exterior glazing that is between 2'6" and 10' in height.
Consider which kinds of controls, sensors, and automation systems are applicable and useful for your project. Refer to the Whole Building Design Guide webpage, which lists different space types with their most applicable controls or sensors. (See Resources.)
MERV ratings are measured by ASHRAE Standard 52.2 and range from 1–16, rating the filter’s ability to remove small particulates in the ventilation system. Sixteen is the highest level of filtration available as measured by ASHRAE 52.2.
Reduce energy use with lighting controls such as daylight sensors, occupancy sensors, nighttime setbacks, and dimmers, even though they don’t reduce lighting power and won’t help for this credit.
Lighting loads can be reduced through by using indirect lighting, lower ambient light levels combined with efficient task lighting, and efficient fixtures such as LED’s, T5 fluorescent lighting, and compact fluorescent lighting.
In spaces that are used primarily during the daylight hours, early design direction to provide daylight harvesting and to select high-efficacy fixtures can decrease the number of light fixtures. This can lead to significant reductions in installed lighting power, often in the range of 15%–20%.
Lamps that are high in powerdensity are halogen and incandescent—avoid these types of fixtures to lower your overall installed lighting power. Instead use high-efficacy lamps such as LEDs, T8 and T5 fluorescents, and compact fluorescents.
Project teams seeking pre-approval for an IO strategy may submit a credit interpretation ruling (CIR) explaining the proposed approach in as much detail as possible.
