LIGHTFAIR INTERNATIONAL SEMINAR PREVIEW If late one night, after everyone has gone home, you find yourself sitting on top of a 10 ft ladder with a can of spray paint and a roll of duct tape, you are most likely involved in an 11th hour fix. In some cosmic sense, you are probably being punished for sins committed earlier in the lighting project. Most of us love the design concept phase, tolerate the design documentation phase and delegate the project management phase. It is not surprising that things go wrong during the phase where we spend the least amount of quality time. Except for back luck, most of the things that can go wrong with a lighting project are identifiable and avoidable. Good communication and documentation throughout the project from concept to focusing will go a long way towards avoiding the things that can go wrong. Join Addison Kelly and David Apfel for an illustrated tour through a typical 11th Hour Fixes Preempting disaster, by learning to sidestep the pitfalls of construction during the design process can save time and money. David Apfel and Addison G. Kelly will help designers avoid 11th hour fixes. FRIDAY, JUNE 1, 2001, 2:00 - 3:30 PM lighting design project. We will identify the potential pitfalls and where they occur in the project schedule. We will review each problem area and indicate the steps that can be taken to avoid 11th hour fixes. Listed below are just some of the things that can go wrong during the construction and focusing phases of a project: Construction Phase • Contractor refuses to order lighting equipment in a timely manner, hoping that a delivery crisis will allow him to substitute. • Lighting equipment manufacturer cannot meet schedule. • Poor documentation or construction site conditions result in relocated ductwork, tight ceiling plenum conditions, and light coves not correctly built. • Lighting equipment installed in the wrong location. • Wrong lamps are installed in the luminaires. • Wall washers are installed lighting out into the room. • At a pre-completion walk-through, before the finishing materials and furniture are in place, the space feels too bright or too dark. Focusing Phase • No one ever notified the lighting designer that the project was complete and the lights needed to be focused. • The contractor has left with his ladders, lifts and scaffolds. How do you reach the lighting equipment? • The luminaires are too hot to touch. • The rotation and pivot mechanisms are locked in place and will not move. • Lamps have burnt out in 30 percent of the luminaires. • The local electrical union will not allow the lighting designer to focus the lights. • Your hands get cut because of rough, unfinished, metal edges on the interior of a luminaire. • The luminaires are installed according to plan, but the furniture and art have moved. Also included are illustrated stories of the things that went wrong and how they were fixed by some of the most brilliant lighting designers of our day. Of course, names will be changed to protect the innocent and the guilty. The accompanying illustrations are examples of specular materials interacting with light sources in a manner never intended by the interior designer or the lighting designer. Join us and learn how to avoid the 11th hour fix. David Apfel is the owner of David Apfel Lighting Design in New York. Addison Kelly is a principal for US Lighting Design Consultants, also in New York. 66 LD+A/May 2001 www.iesna.org
LIGHTFAIR INTERNATIONAL SEMINAR PREVIEW The Need for Control Deciding what types of lighting controls to use in an application is of primary importance. Harold Jepsen, Leslie North and Sandra Vasconez will provide help in making the decision easier. THURSDAY, MAY 31, 2001, 4:00 - 5:30 PM For most facilities, lighting systems management personnel value the are second only to HVAC systems in increased convenience in maintaining terms of energy usage. Controlling optimal building operations with automated controls. For occupants, the these systems is an inextricable part of the entire lighting equation. There are advantages of optimal lighting and some unavoidable reasons for controlling lighting, such as complying with comfort and satisfaction with personal adjustable light levels can lead to greater energy code provisions that require work environments. automated lighting controls in non-residential facilities. companies that are implementing light- While it’s clear to a growing number of However, beyond basic compliance, ing controls that there is great potential lighting control can provide a variety of for enhancing the operation of a facility, benefits for building owners, managers many also acknowledge that developing and occupants. For building owners and a lighting control project offers considerable potential for pitfalls. An inadequate managers, the potential energy savings involved with lighting control can be or ineffective controls system can create substantial — often 30 percent of total more obstacles than an absence of controls, as dissatisfied or frustrated electrical usage or even greater. Facility occupants may disable or destroy devices to resolve their concerns. “Control Me!” provides a roadmap through the design, selection, and implementation of lighting controls in a “real-world” context. Structured around real-life applications commonly found in commercial settings, this seminar provides attendees with a comprehensive overview about the entire lighting controls process, from a logistical perspective, as well as a results-oriented perspective. For instance, seminar leaders will explore common applications such as open office areas, private offices, conference/training rooms, restrooms, common areas and exterior lighting. In each setting, topics for consideration include what the needs of the user(s) are. This includes an assessment of who — if anyone — feels “ownership” of the space, as well as other factors, such as the presence of daylight. In addition to user needs, other topics include how to select a suitable control strategy, what application-specific challenges might appear, and results or insights gained from recent research or case studies involving similar applications. Before exploring each specific application, the seminar reviews some of the basics in beginning a lighting controls (left) In conference rooms, user needs include flexibility and ease-of-use for selected controls. Architectural dimming controls may be an appropriate solution. (right) In an open office setting, there is limited space “ownership” by occupants. There is a need for daytime lighting and the ability to override controls after hours. This is accommodated with scheduled control and the use of local “smart” switches. 68 LD+A/May 2001 www.iesna.org
