 The new 11-story, 422,000-square-foot, state-of-the-art Mount Sinai Center for Science and Medicine located on Madison Avenue in New York City is being designed to unite clinicians, scientists, educators and their colleagues in an interactive space while expanding Mount Sinai’s research and treatment programs. With high aspirations for collaboration in this joint clinical research and ambulatory care cancer center, Mount Sinai has designed education spaces, lounges and computer facilities, basic science research space, the Mount Sinai Brain Institute and Spinal Cord Injury Research Center, the Center for Translational and Molecular Imaging, the Cancer Center and a multistory lobby to maximize the organization’s ability to provide an appealing location for specialty outpatient care and clinical research. As a result, Mount Sinai selected GE’s lighting control products when designing and constructing the new building.
Brazill Brothers will be providing a GE LonWorks®-enabled ProSys LM Lighting Control System™ for the Mount Sinai Center for Science and Medicine. The ProSys LM Lighting Control System is composed of a network of relay panels and occupant control switches lined by a 4-wire dataline to form a reconfigurable, “softwired” switching platform that links occupant switches to relays and relays to lighting groups or zones. A network of ProSys LM panels can accept a virtually unlimited number of intelligent devices such as panels, switches or LonWorks-enabled lighting systems, ensuring seamless integration into building automation systems and reducing expansion costs over time.
GE ProSys panels installed on each floor of the medical center will work together to control lighting in various zones of the building, insuring that the diverse needs of different sections of the building are being met at all times, whether a laboratory or lounge. Built-in timers will provide easily customizable, automatic-timing functionality, allowing for lighting on/off scheduling for every day of the week and 32 holidays, as well as integration with daylight harvesting technology for maximum illumination efficiency. A web-based, front-end user interface will also allow for technicians to easily configure lighting schedules and monitor performance based on live usage reporting through a standard web browser, ultimately ensuring consistency and electricity savings throughout the medical center.
With the Mount Sinai Center for Science and Medicine scheduled for completion in 2013, GE Lighting, in conjunction with Brazill Brothers, will remain an important contributor to Mount Sinai as lighting systems are tailored to create an inviting location to visit and work over the next several years.

University of California Santa Cruz’s (UCSC) Science and Engineering Library is one of two campus libraries that serve over 16,000 students. The school was concerned that existing lighting was fully activated in the morning and remained on until the cleaning staff left nearly 20 hours later, leading to daily energy waste. Occupancy of the building varied greatly day by day and did not follow a reliable pattern. Facing time constraints and the potential high cost of conventional wired technologies, the energy team chose to utilize Leviton’s LevNet RF products using EnOcean’ s energy harvesting technology to achieve their energy goals.
The LevNet RF receivers were paired to wireless occupancy sensors and light sensors that control the updated and more efficient T8 light fixtures. The wireless light sensors control all perimeter lighting fixtures adjacent to windows and takes advantage of daylight harvesting. When there is an abundance of ambient lighting, these sensors will keep the lights off resulting in greatly reduced energy waste. The lighting upgrade at UCSC, combined with the introduction of Leviton occupancy sensors, reduced energy consumption by 50 percent in the facility representing an anticipated $48,000 annually savings in energy costs. The university was also able to make use of an energy rebate incentive for the replacement of the inefficient T12 light fixtures and an additional incentive was given for the occupancy and light sensors that further reduced the project cost. The project was also given the “Best Practice Lighting Award” at the 2011 California Higher Education Sustainability Conference.
“We are very excited to have our LevNet RF wireless lighting control used in this award winning and innovative project,” said Richard Westfall, Vice President and General Manager for Leviton’s Lighting & Energy Solutions. “Energy conservation has never been more important, from both an environmental and economic perspective”.
The EnOcean Alliance, a 250-member consortium of companies working to standardize and internationalize energy harvesting wireless technology for green intelligent buildings, has awarded the University of California Santa Cruz (UCSC) with its prestigious “Wireless Innovation Project of the Year” award. The award is designed to promote innovation and increase implementation of wireless energy harvesting green intelligent building technology.

This month, we will explore the role that sophisticated lighting controls play in typical rooms and suites at the Wynn Las Vegas resort and casino, which won an Award of Merit. Lighting design by Wynn Design and Development. Photography by Bradley A. Bouch. Control manufacturers/products: Evolve Controls.
This multi-million dollar resort hotel renovation upgrades finishes, furniture, amenities and the environmental control systems in all 2700 guest rooms and suites.
Requested by Hotel Operations, the lighting and HVAC systems in each room were upgraded from manual lighting and HVAC controls to an integrated guestroom control system operating all architectural and decorative lighting, room temperature, window coverings, doorbell and room service options. Requested by the Interior Design team, the control devices were manufactured in custom colors. The amber LEDs backlighting the control station buttons were customized to meet hotel standards. The control system turns on the lights, opens the drapes and sets the temperature when guests first enter the room.
This cost effective, wireless, environmental control system required no changes to the existing room electrical wiring. Guests now have total control of the room environment from tabletop, bedside and wall mounted control stations. Allowing guests to control their lighting, temperature and service needs from several locations within the room enhances the luxury atmosphere of this resort hotel. In exiting surveys, guests identify the new control system as the most significant upgrade to the guest experience
When guests are relaxing, the lighting controls provide three levels of lighting intensity. Shown above is lighting set at “High” in the living room.
Shown above is the medium light level.

This month, we will explore how designers tackled the challenges of upgrading the lighting and controls at a historic cathedral, the First Congregational Church of Los Angeles. This project won an Award of Merit. Photography by Anthony Masters Photography. Lighting control design by First Circle Design, LLC. Control product used: Unison Paradigm control system by Electronic Theatre Controls, Inc.
Upgrading the lighting and controls for this historic cathedral presented complex challenges. The existing sanctuary lighting control required manual switching at the breakers. The control systems needed to support the function of an active environment and also provide a dynamic event capacity via simplistic interfaces. Existing conditions offered no lighting control infrastructure, restricted electrical capacity, and limited conduit locations.
Multiple control locations, asynchronous recall of presets, and auto-preset settings for different times of day/days of the week were control requirements for Services. Holidays required an array of predetermined presets, triggered via a push-button. Finally, the system had to be capable of being controlled by an external theatrical console for events.
Wireless data distribution conserved infrastructural penetrations, while a new dimming system provides independent area lighting for Services. A wall-mounted control interface offers Entry presets and a wireless interface manages multiple-location scene selection during Services. A DMX port for an external theatrical console completes the system.
Standard operations run via astronomical time-clock. Entry presets trigger Day, Night, and After Hours scenes.
An access code at the interfaces grants access to further extensive preprogrammed scenes. These can be selected and custom-configured without external programming.
A password protected interface button releases control for theatrical productions.
The architecture and utilization of the Sanctuary determined zoning, providing multiple ‘zones’ for both small and large-scale controllability.
Control zones designated as follows: ‘Pulpit’, ‘Deacon’, ‘Choir’, ‘Reredos’, ‘Balcony’, ‘Gallery’, ‘Rose Window’, and ‘Congregation’.
To allow for specific needs of a speaker/signer, all key-lighting is individually controlled via virtual slider on the touch-screen.
The control system was designed to provide automated operational triggers and any-time, live-event flexibility, with minimal infrastructural impact. Utilizing wireless DMX in conjunction with LED technology
preserves the historic grandeur of the cathedral and also successfully addresses the complex challenges of a flexible and dynamic environment.

This month, we will explore the role that sophisticated lighting controls play at the City of Dreams Resort, Bubble Theater/ Macau SAR, creating an immersive virtual underwater experience with media and light. This project won a Special Citation Award for the use of controls in an entertainment lighting project. Photography by Jason Goldenberg. Lighting control design by Lightswitch Architectural Inc.
The design challenge was to make an asymmetric domed space, an immersive experience with media and light, pushing the possibilities of the built environment. The designers coordinated the addition of an interior skin that would be elliptical, and symmetrical, so projected images would not distort.
The dome becomes a seamless projection surface with 15, blended 30,000 lumen video projectors along with 10,000 LED’s interlaced within the perforated dome. The LEDs provide pixel mapped support of the content enhancing bubbles, sparkles, explosions and magical auras surrounding animated characters.
The elaborate control system is both DMX and video driven through a massive control network, in addition to relay control for afterhours shutdown.
Designing the lighting and lighting controls system, each of the thousands of lighting elements/luminaires are individually controlled with approximately 50,000 channels, and 80 universes.
The designers coordinated maintenance schedules and system training with operations staff, designed access to the equipment via elaborate multistory catwalks, and follow-up with annual site visits.
Designed with touch screen diagnostic checks, a clearly defined system criteria and creative intent keep the system operating per design intent.
Kinetic sea creatures fly in and out of the space, and did not allow for data to be run. So wireless access points sourced from the IT industry are used to transmit data for control.
Custom coral chandeliers house strobes and RGB LEDs, controlled via pixel mapping.
A true marvel of media and lighting design integration.
On-site to commission, coordinate, and program controls, the designers provided a systems integrator for a year, and an average of seven designers for five months.
Energy efficiency: The designers used only arc lamp metal halide and LED sources, and the system contains a total of 234 W/sq.ft. to accommodate the endless variety of environments.
Budget: The design team provided an $8 million installed lighting budget and came in 5% under budget.

This month, we will explore the role that energy-saving lighting controls play at the Cleveland Public Library Rice Branch, a new building that achieved a LEED Silver rating. Photography by David Joseph. Control manufacturers/products: Lutron Electronics’ Quantum, EcoSystem, Sivoia Shading Solutions, GRAFIK Eye QS. Lighting control design by Tec Inc Engineering & Design.
Multiple control strategies were implemented into the design of this new construction urban public library. At 14,000 sq ft, it became the first freestanding public library in the state to achieve a LEED Silver rating.
Direct-indirect luminaires float gracefully within the open space providing just the right amount of illumination to meet the targeted goals. Photosensors are integrated into the luminaire and wired back to DALI ballasts.
The lighting control plan shows the openness of the space and the minimized amount of circuits needed. The DALI system separates the control from the power, making the installation more flexible for the changing needs of the collection over time.
The one-line diagram illustrates the full system of strategies combined on this project, including: daylight harvesting, occupancy sensing, scene control and automated shading.
Ballast tuning was employed in the soft seating areas where a reduced footcandle level was desired. With a high-end trim set to 65% the LPD went 1.13 down to 1.06. This amounts to a savings of 19% compared to energy code 90.1-2004.
Highlighting the area seen above showcases the need for varied lighting levels over multiple task types within continuous linear runs of luminaires.
A close-up of the plan indicates the desired light levels of both the daylight harvesting and tuning. Without the DALI system, this would have proved a challenging wiring project for the Electrical Contractor.
Lighting controls were located at the main circulation desk and were also tied to an astronomical timeclock that could be triggered at each entry door for unexpected after-hours staff.
Full scene control was implemented into the meeting space seen here, with shades fully open for maximum daylight contribution.
An evening scene showcases the seamless integration of the varied light levels without detracting from the overall appearance of the space.

Inside Building 801 at the Boeing facility in Long Beach, California, there’s no shortage of big brains and high-tech marvels. That’s where the company is busy designing military aircraft such as the C17 “Globemaster III” transport plane for the U.S. Air Force.
The building houses a wide variety of impressive technologies, some of which have nothing to do with aviation. In fact, one of the latest additions is a brand new lighting system designed by Boeing facility engineer Jeff Haberman.
Haberman wanted to retrofit Building 801 with automated lighting controls that would significantly reduce the facility’s overall energy needs. Specifically, he wanted three things:
* To add photocells for daylight harvesting in all the offices and areas around the perimeter of the building where windows were providing natural light
* To install occupancy sensors in all corridors, private offices, break rooms, and conference rooms
* To set up an automated scheduler to reduce light levels at specific times of day
In order to design the new system, Haberman identified three different technologies that could provide him with the capabilities he was looking for: 0–10V dimming, DALI dimming, and DCL technology from Universal Lighting Technologies.
The first two solutions would force Boeing to install new control wiring throughout the building—an expensive prospect. They would also require a separate control system designed specifically for lighting. DCL, on the other hand, requires no additional control wiring. Instead, it communicates over the existing power circuits. Plus, DCL was fully compatible with the facility’s existing Building Management System (BMS).
As a result, the estimated cost of a DCL retrofit was 40% lower than either of the other two options—and only 5% more than the cost of a traditional lighting system! What’s more, the payback period for a DCL retrofit was less than 2.5 years, compared to approximately seven years for either of the other systems (including utility incentives).
 As you might guess, Boeing selected the DCL solution. According to Haberman, DCL required 90% less wiring than other systems, 60% less hardware, and 70% less programming. And he calls the installation “a piece of cake.”
The entire installation took place in November and December of 2010. All told, 2,050 fixtures were replaced. Each new fixture contains either two or three 32-watt T8 lamps attached to high-efficiency DEMANDflex ballasts from Universal Lighting Technologies. Each DEMANDflex ballast was “tuned” during installation to the optimal light level (ballast factor) for its specific environment, helping to eliminate the common—and costly—problem of over-lighting. These ballasts are specifically designed for DCL technology in order to communicate with the BMS at the circuit level.
Every night, the BMS signals the ballasts to cut power by 50% at 6 p.m. while the cleaning crew is in the building. At 7 p.m., the lights turn off. Of course, anyone still working in the building has the ability to override these commands and temporarily keep the lights on in his/her area. This can be done from any desktop computer or from a password-protected touchscreen display near the elevators on each floor. In addition, occupancy sensors reduce power levels to 34% in each office or common area when they detect that these spaces are unoccupied. And photocells automatically reduce unnecessary artificial light in areas near windows whenever they detect sunlight.
Haberman calls the control system “pretty darned simple” and reports that employee reaction has been “very positive.” And the results are outstanding: “We’ve seen a nearly 60% reduction in energy use for lighting,” said Haberman.
In real-world numbers, the lighting system in Building 801 previously required 950,000 kWh per year. The number now is approximately 400,000 kWh per year. That amounts to a 57% reduction in energy costs for lighting alone, or a 15% reduction in the building’s overall energy needs. “It works great,” said Haberman. “No other system comes close.”
As if that’s not impressive enough, Boeing also participates in a Demand Response Program with its local utility. This allows the utility to automatically reduce power to Building 801’s lighting system by 30% whenever the local power grid is near capacity. Not only does Boeing reduce its energy by 15.8 cents for every 1 kWh it saves through this program, but the utility provides Boeing with a $3 incentive for every 1 kWh saved as well.
How easy is it to reduce energy consumption and monthly power bills with DCL? According to Haberman, “Basically, it’s bulletproof.”
