  • Daylight Harvesting Methods and Practice by Bryan Palmer, ETC Architectural Controls Product Manager
    White Paper Daylight Harvesting Methods and Practice by Bryan Palmer, ETC Architectural Controls Product Manager Introduction Daylighting for energy savings and conservation has become common design practice. Daylight harvesting is something that is required by some energy codes, and soon to be adopted by oth- ers. Instead of being encouraged by energy programs, it’s becoming required. California’s Title 24, IECC 2012, and ASHRAE 90-1 already have daylighting guidelines; and they are likely to become more stick over the coming years. Most commercial buildings that have windows and skylights are required to have some type of daylight harvesting control in the adjacent area. Green sentiment and construction practices bring additional attention to energy saving practices like Daylighting, help to further acceptance of the practice, and grow the technology that makes it possible Daylight harvesting’s proposed value is simple: As natural light levels increase, electric light levels can be decreased to maintain an acceptable level of light in a space, and save energy (and mon- ey). Daylighting systems automate this process, removing the human element of control by using a light sensor that measures light levels and sends them to a controller that is connected to the lighting control system. The control system can then dim or switch electric lights in response to the measured level. The light sensor is typically small, and uses a light-sensitive photocell, input optics and an electron- ic circuit used to convert the photocell signal into a control signal. Light Sensors may be mounted on walls, ceilings and even as a part of light fixtures.

  • Daylighting Application and Effectiveness in Industrial Facilities
    Daylighting Application and Effectiveness in Industrial Facilities Brian McCowan, Energy & Resource Solutions, Inc. Daniel Birleanu, Energy & Resource Solutions, Inc. Natalie Hildt, Energy & Resource Solutions, Inc. ABSTRACT Historically, daylighting has been extensively used for the lighting of industrial spaces. Before the advent of practical mercury vapor and fluorescent lighting, the only available artificial lighting for industrial buildings was incandescent. The illumination of active industrial workspaces with incandescent lighting is difficult, so during the industrial revolution, architects utilized various daylighting strategies such as window walls, skylighting, monitors, etc. However, glazing technologies were also primitive compared with our modern glazing choices, and space conditioning and glare problems plagued day-lit spaces. When more efficient and effective artificial lighting became available, most older day-lit industrial buildings had their daylighting features boarded over. With modern glazing systems and sophisticated designs that minimize glare issues, daylighting for industrial buildings is making a strong comeback. Additionally, new controllable ballasts and automatic lighting controls make possible hybrid lighting systems that are able to provide optimal lighting under all environmental conditions. This paper will demonstrate discuss how the daylighting systems developed decades ago are being modernized to provide high quality, low-glare, uniform lighting, without the space conditioning penalties of the past.

  • Daylight Harvesting for Today's Buildings©
    Daylight Harvesting for Today’s Buildings© By: Sam Lallas ’ 310 Melvin Drive, Suite #19 Northbrook, IL 60062 I T: 312.376.0100 I F: 312.262.6390 I [email protected] _____________________________________________________________________________________ As technological advances facilitate much finer degrees of control over a building's internal Environment, the expectations of users for levels of comfort, controllability and energy efficiency have moved to take advantage of new possibilities. The result can be an almost symbiotic relationship, in which buildings are able to work with their occupants in a far more dynamic manner than has ever previously been possible. One aspect that is attracting great attention is in finding the optimum balance between natural and artificial light. The energy efficiency of a building and occupant comfort can be profoundly affected by the building's orientation to the sun. Sunlight falling on a building façade usually results in both heat and light transfer to the interior. While these may be welcomed during winter, they often cause problems through overheating and glare in summer. The focus historically, especially in hotter climates, has therefore tended towards mitigation strategies against the effects of solar radiation. Fixed shading can prove effective in this respect, particularly in terms of blocking solar heat, which would otherwise lead to the need for additional cooling and the requisite energy to provide that cooling. However, emerging green targets and occupant comfort factors have spawned a new appreciation for the benefits of natural light, leading to the practice now known as 'daylight harvesting'. This has shifted the focus towards building designs that are flexible enough to protect against the summer heat, while still able to embrace natural light and heat at other times.
