Occupancy sensors are mounted in the ceiling or on a wall switch, available in passive infrared (PIR) or “dual-technology,” which incorporates PIR plus either a microphonics or ultrasonic sensor.The control requirements and devices are: Reference Chapters 6, 8, and 9 of ASHRAE 90.1 for more information, exceptions, and sequences of operation for specific space types. Exceptions should be cleared with the client prior to removing them from the design. There are many exceptions to certain control requirements including 24-hour operation and security or safety concerns, among others.

The following is an overview of the basic lighting control requirements and devices to consider during design and is by no means an exhaustive code review.

These added control measures force the designer to completely reimagine how to control lighting. The 2010 version introduced automatic receptacle controls, drastically cut down the LPD limits, added occupancy- and daylight-sensor requirements, and added bilevel switching requirements, effectively expelling line voltage systems. For example, when ASHRAE 90.1-2007 applies, one could comfortably use typical multilamp 28-W fluorescent tube fixtures, line voltage switching, and other basic controls and still meet code. As the LEED certification level goes up, so does the energy savings required in the building-wide energy model. To help cut building-wide energy usage, lighting designers can attempt to limit their LPD as much as possible by using more efficient fixtures to contribute to overall energy savings. If a building is pursuing LEED certification, the energy-model credit specifies a percentage lower than what is allowed in ASHRAE 90.1. Each version becomes more strict, lowering LPD limits on spaces and increasing control requirements all in the name of energy savings. Note that ASHRAE 90.1 has four versions listed above because state adoption of the standard varies and may reference one of those versions that are referenced. Unless the client has their own required foot-candle levels spelled out, they typically reference this as a source for lighting levels.ĪSHRAE 90.1, Chapters 6, 8, and 9, were developed to drastically reduce overall building energy usage by imposing strict controls to HVAC, lighting, and power.įor lighting, ASHRAE 90.1 provides required LPD limits and control schemes for several common space types. It’s a great source for everything from a dormitory bedroom to an outdoor mechanical yard at a manufacturing plant. The 2011 version of the IES Handbook provides recommended foot-candle levels for various indoor and outdoor spaces. Various state, city, campus or client-provided standards also must be considered. For military projects, the Unified Facilities Criteria (UFC) documents, such as UFC 3-530-01: Interior and exterior lighting systems and controls, with Change 3, also show requirements for what is expected in facilities. Two main standards driving the design of lighting and lighting control systems are the IES Illuminating Handbook (2011) and ASHRAE 90.1, Chapters 8 and 9 (2007, 2010, 2013, 2016). Three-dimensional-rendered models are not an option for all consultants. With minimal effort, adding some small details and color can look impressive.

Minimize glare from intensive computer screen areas by looking at indirect and direct fixtures with shielding on the downlight side of the fixture.With so many options for LED lighting fixtures, even obscure architectural fixtures can be used and still meet codes.Aim to be within +/-10% of the target foot-candles typically found in the Illuminating Engineering Society ( IES) Lighting Handbook. Overlighting a space can be as undesirable as underlighting a space.To meet the LPD limits of the new ASHRAE 90.1 edition, IECC, or California Title 24, you’ll most likely want to use LED fixtures instead of more energy-intensive lighting options.There are many control systems available that make design and installation easier. Most spaces now require more lighting controls than a simple on/off toggle switch.Here are some general principles to follow when reviewing requirements for a new construction or renovation lighting design project: It is no longer two, three, or four lamps that are easy to distinguish.

It is also an educational effort for installation contractors to verify that the fixture has the correct driver installed, as the fixture from the outside looks the same. It can be a delicate balancing act between meeting the required foot-candle levels, staying under the watts-per-square-foot LPD limits using an appropriate fixture, using the appropriate driver size, incorporating the required controls, and finally showing this in a clear and concise manner on construction drawings so a contractor can decipher what it is you’ve tried to design.
