Excessive and unrestricted light from bollards, columns, and post tops can negatively impact people, animals, and the environment. However, fixtures that are designed to Dark Sky specifications can dramatically reduce the amount of sky glow and light pollution while saving energy and mitigating impact on the environment. This learning unit will explore the concept of Dark Sky and how architects can specify luminaires to help reduce light pollution and encourage a healthier and more responsible approach to lighting.
The Payback calculator will quickly scope out just what you can save based on wattage, hours of operation, number of fixtures and other parameters.
Low voltage distribution systems (LVDS) can offer an efficient and cost-effective alternative to traditional high voltage systems, but until recently were relegated to path lighting and decorative accents. With the advancement of LED technologies, LVDS can finally move inside and be utilized as the backbone for a general lighting strategy. LV lighting systems have voltages that are lower than 30 volts DC and use a Class 2 power source, and they are considered much safer during installation, maintenance, and use. Consequently, these systems carry different and more lenient electric safety code requirements.
This course will explain the background context of traditional and low voltage systems, including their common uses and code requirements, and will explore the benefits of combining a LV distribution system with LED lighting for general lighting systems. Also, this learning unit will address installation, insulation, maintenance, and potential cost savings associated with specifying an LVDS for general lighting. Finally, this course will look at how LV systems can be used effectively to address emergency lighting requirements.
Help keep operating and maintenance budgets in check – get a better understanding of how upgrading lighting in streets, public buildings, walkways, parking structures and common areas will help.
Lighting design for office buildings has focused largely on providing sufficient illumination for visual performance, minimal glare, good color rendering and energy efficiency. Little attention has been given to understanding how light affects the non-visual systems, including circadian regulation that affects sleep and mood. This course will discuss basic information about the importance of light and dark for entertaining circadian rhythms will be discussed. Findings from the field evaluation will also be presented with some “lessons learned” on how to maximize daylight and electric lighting in a space to increase circadian stimulation.
Expert panelists define circadian lighting and provide insight as to how it impacts the human body. Referencing the WELL Building Standard®, an evidence-based performance standard for measuring and certifying building features that impact occupant health and wellness, learn how to design for circadian lighting in different environments. What does a circadian smart space look like? Are there tradeoffs? Panelists will present examples of technologies that help accomplish these metrics, and show images of completed projects that have implemented circadian-smart designs.
The City of Los Angeles upgrades streetlights to Cree LEDway luminaries to achieve an estimated energy and maintenance cost savings of 10million annually.
This learning unit provides a general overview of how new technologies allow for greater control of LED fixtures, light quality, and lumens. This unit also illustrates the benefits of LED lighting compared to other traditional bulb types. Finally, architects will learn how LED fixtures offer new options and benefits specifically intended to create unique and functional interior lighting designs.
Daylighting Inside and Out: Unconventional Ways to Bring More Natural Light Into and Throughout a Building
Exposure to natural light is beneficial for building occupants on many levels. We all know it intuitively and we feel better in interior spaces with natural light. Plus, studies conclusively demonstrate measurable benefits for health, moods, learning, and productivity.
The time-honored method for allowing natural light into a building is, of course, through windows. However, there are many more strategies for bringing natural light into and throughout a building. This course explores the sometimes-overlooked strategies for the flow of natural light into and throughout a building, including light tubes in closets, French doors in interiors, natural-light-flooded stairwells, sliding glass walls, and more.
This course will cover the fundamentals of lighting, with a focus on light emitting diodes (LEDs). The course will cover ways to measure light, the visual perception of light, how different light sources can render color, as well as the production of LEDs and industry standards for LED products.
