Interior: Zoning is required for occupancy sensing, high-end trim, and daylight harvesting control strategies except for systems that feature luminaire level lighting control (LLLC) capabilities as defined in these requirements under “Reported Capabilities”, in which case zoning is only required for occupancy sensing and high-end trim control strategies. Daylight harvesting systems use daylight to offset the amount of electric lighting needed to properly light a space, in order to reduce energy consumption.This is accomplished using lighting control systems that are able to dim or switch electric lighting in response to changing daylight availability. Connectivity. 0000009356 00000 n Demand for daylight harvesting controls has grown dramatically in recent years, driven largely by sustainability initiatives such as LEED. 4. 0000034760 00000 n Two-step control, which is the minimum requirement in Standard 90.1-2010. In 2008, California set a goal to achieve zero net energy (ZNE) in new commercial buildings by 2030. The minimum requirements apply to both conditioned and unconditioned spaces that are: 1. 452 0 obj <>stream Have a ceiling height greater than 15 square feet 4.

Now the major energy standards—IECC and ASHRAE/IES 90.1—contain significant requirements for daylight harvesting control, signaling widespread acceptance and adoption of this control strategy in the future. Ensure good natural daylight and visual comfort, reduce lighting gains, and test how your lighting designs will look and perform. Open loop daylighting: Lights are adjusted based on natural light in … %%EOF Unit will gradually dim lighting in order to maximize energy savings while maintaining desired overall lighting level.

Additionally, perimeter lighting in parking garages is required to be automatically reduced in response to daylight, with some exceptions. Education 5. Another 2003 study, conducted by Heschong Mahone Group, found that daylight harvesting strategies can produce 50% energy savings in school classrooms. 0000003188 00000 n Is Daylight Harvesting Required? After dimming to low trim level, unit can optionally be enabled to turn off lights completely. 417 0 obj <> endobj Daylight Harvesting Systems Our advanced daylight harvesting systems are of highly creative and innovative designs that gather and inject natural smooth daylight indoors for longer hours while blocking heat and glare to greatly elevate mood and aesthetics in our everyday lives. Hospitality 5. Factors such as bi-level and multi-level switching or dimming capability as well as separate circuiting of luminaires in daylighted zones enhance both the usability of a space and energy savings. Further, the Green Interior Design & Construction version of LEED further awards 2 points for introducing daylight harvesting controls in all daylighted areas (1 point) and/or on 50% of the lighting load (1 point).

The “Daylight” credit under the Indoor Environmental Quality (IEQ) category has been updated in LEED v4 to incorporate new metrics. Show More Show Less. ASHRAE 189.1 is a green building standard. An EnOcean-based daylight harvesting system consists of a wireless relay controller LEDR, one or more energy harvesting wireless occupancy sensors, a light level sensor, and one or more wall switches as shown in the figure above. All of these codes and standards are different and yet have similar major themes. to have a minimum amount of daylight available. Ten Key Daylight & Electric Light Metrics .

Wired 1. on customer requirements in each space. First, they define daylight availability as zones around sidelighting (e.g., windows) and toplighting (e.g., skylights and roof monitors) daylight apertures. The controller communicates via the Its main purposes are to conserve energy and to provide people with healthy, natural light even when they’re indoors. 90.1-2010 or governmental energy code requirements such as Title 24 in California. Usability Allow for user adjustment and override. What is Daylight Harvesting? IECC 2009 offers a basic approach to daylight harvesting control by simply stating that general lighting in these zones must be separately circuited and controlled from other general lighting in the space. Because energy savings will be dependent on factors such as type of available daylight, control response and space and task characteristics, actual savings can be difficult to predict, although studies suggest strong potential. To reach this objective, new construction Area/Site Lighting Outdoor lighting improves the appeal of a property and plays a critical role in providing safety and security. Lighting controls also help meet daylight harvesting control code requirements. Outdoor Lighting 3. As with sidelighted spaces, more aggressive daylight harvesting control in toplighted areas is rewarded with power adjustment credits. • Integrated photocell with Adaptive Daylight Harvesting (ADH) • Vandal resistant lens • Fully meets NEC 2017 Section 404.2C neutral requirements - no current leakage to ground when connected to neutral • Ability to aid in IECC and ASHRAE Code Compliance WSX D Dimming Occupancy Wall Switch ORDERING INFORMATION Catalog Number: Date: Project: NOTES: 1.

Daylight harvesting is an advanced lighting control strategy used to minimize ongoing owner energy costs. Solar harvesting refers to the proper collection and management of incoming IR solar radiation from the façade components in order to enhance the thermal behavior of a building and achieve mitigation of solar loads or harvesting of solar energy to offset mechanical system requirements. Retail 5. Warehouse 5. Both IECC 2009 and ASHRAE/IES 90.1-2010 define daylight zones using formulas based on size of aperture and whether there are any obstructions blocking the light, with ASHRAE’s approach being similar to ASHRAE 189.1 and California’s Title 24-2008 code. Section 9.4.1.3 of ASHRAE 90.1 stipulates: Now the major energy standards—IECC and ASHRAE/IES 90.1—contain significant requirements for daylight harvesting control, signaling widespread acceptance and adoption of this control strategy in the future.
