Background

Rolls-Royce doesn’t just design and manufacture cars. They are a global company that creates highly-efficient integrated power and propulsion solutions, predominantly used in aerospace, marine, energy, and off-highway applications. The Engine Services unit in Oakland, CA provides maintenance, repair, and support services for military customers using Rolls-Royce engines.

Situation

Recognized as a global leader in sustainability initiatives, Rolls-Royce has continuously focused on understanding energy use to identify inefficiencies and opportunities for improvement across all their business units. Their Engine Services division needed to upgrade their lighting system to one that would allow them to reduce their energy consumption and improve their productivity through higher quality lighting quality throughout their facility.

Solution

Eco Engineering began this project with an audit to identify and design the best lighting solutions to meet Rolls-Royce’s unique lighting needs. Specifically, Rolls-Royce needed to ensure that the lighting system could withstand the extreme wind, heat, and vibration characteristics of an engine testing facility. Additionally, Rolls-Royce required lighting for their office spaces. While this interior lighting system had less demanding requirements, the retrofitted LED system still needed to be outfitted with occupancy and motion controls to regulate and reduce unnecessary light output.

The primary components of this lighting retrofit involved removing T8 fluorescent fixtures that were hot, inefficient, and produced poor light from the production areas, offices and exterior lighting, and replacing them with new energy-efficient LED lamps and ballasts. The longer-lasting LEDs were cooler and required less maintenance, as a result, Rolls-Royce not only saved on energy costs, but they were also able to find modest savings in both maintenance costs and lower air conditioning expenses.

Background

JBG Companies is an active investor, owner, and developer in the Washington DC metropolitan area’s real estate market – one of the most dynamic markets in the world. Their diverse portfolio encompasses millions of square feet of office, residential, hotel, and retail spaces, and includes many of the region’s most distinguished properties. JBG’s sustainability efforts are centered around creating value through the strategic design, development and management of properties that result in energy efficiency, resource conservation, and waste reduction.

Situation

JBG links sustainability to the core business of creating and preserving real estate values. The Renaissance Arlington Capital View, which opened in 2011, is a 300-room, full-service hotel located in the heart of Crystal City’s dining and business district in Arlington, Virginia. The hotel is Gold LEED-certified and boasts award-winning architecture inspired by motion and enhanced light. Despite the impressive energy efficiency of the property itself, the property’s parking garage needed to upgrade the outdated lighting system. This would not only yield operating savings with a direct impact on real estate value, but it would also add to the significant environmental impact JBG deems a priority.

Solution

The energy efficient lighting project incorporated new LED canopy fixtures to replace more than 270 metal halide fixtures. Additionally, almost 100 four foot fluorescent fixtures were replaced with new reduced wattage T8 lamps and electronic ballasts. LED wall packs were installed on the parking ramps and the lighting for the entire garage facility was standardized to maximize energy savings and reduce maintenance costs. Careful design and planning was undertaken to account for the traditional challenges associated with a lighting retrofit in an indoor parking facility – insulated ceilings, mechanical rooms, ancillary spaces, loading docks and the need to work around the potential issues of reduced parking capacity during installation.

Both the design/audit and implementation phases were conducted by Eco Engineering.

Background

One of America’s largest municipalities, the city of Cincinnati is steeped in tradition and history dating back to the 1790s. The city is home to some of the most unique architecture in the country, and preservation has long been a Cincinnati hallmark. In recent years, Cincinnati has turned to using modern technology to improve the overall community.

Situation

A community-wide green initiative was endorsed by the city council and a comprehensive contract was awarded to Honeywell Energy Services to design and implement energy savings projects among city-owned properties. Outdoor lighting, especially street lighting, was quickly identified as a significant opportunity to save energy, and with it came the potential to reduce city maintenance expenses. Beyond that, improved lighting quality also carried strong safety implications for the community.

Solution

Honeywell partnered with Eco Engineering to audit, design, and implement the outdoor lighting system. We retrofitted nearly 50 different types of outdoor lamps, using only 12, standardized LED technologies. This project included developing customized street lamps and components to fit historical, antique, and decorative fixtures throughout the city. The lighting project spanned parks, recreation centers, and overpass/underpass lighting. This aspect presented a notable challenge given that many of the spaces that needed new lighting systems were “always on,” and implementations needed to cater to that environment.

The LED solution deployed lamps rated for over 100,000 hours of use, with 10-year warranties that guaranteed enhanced brightness and more consistent performance from street lights over a longer period of time. The resulting maintenance savings were significant.

Background

Brookfield Properties, a fully integrated, global real estate company, renovated The Short Pump Town Center, a premier open-air shopping mall located in the West End area of Richmond, Virginia. The updated center offers more than 140 stores and restaurants, and was designed to be a “community within a community.” The entire mall is pedestrian-friendly, featuring lush landscaping, heated pavilions, beautiful fountains, intimate seating areas, and even play areas for children. Brookfield Properties wanted to make sure that The Short Pump Town Center was the type of place that everyone in the community could safely enjoy.

Situation

Given the purpose for The Short Pump Town Center, it was important to Brookfield Properties to ensure that the mall was as safe in the evening as it was during the day. However, safety wasn’t the only priority, it was also important to improve the night-time aesthetics of the center. Brookfield Properties needed to incorporate an upgraded parking lot lighting solution that would lower energy costs, reduce maintenance costs, and improve light output to ensure customer safety. They came to Eco Engineering to help.

Solution

Eco Engineering performed the design and implementation for Brookfield Properties’ new parking lot lighting system. The new system features LED fixtures which significantly improved the photometric light distribution compared to the existing system. Prior to the upgrade, the parking lot at The Short Pump Town Center contained 137 parking lot light poles, each with four HID fixtures. Eco Engineering replaced each HED fixture with two, new LED fixtures. Additionally, the design allowed each new light fixture to be intelligently controlled. This meant that each fixture on a single pole could be set to operate at a different time, for example, one could be on during the operating hours of the center, while the other would operate only during off-hours from midnight until dawn. The controlled functionality of this system both maximizes energy savings and extends the life of the fixtures.

Background

Cincinnati is one of America’s largest municipalities, and it is steeped in tradition and history dating back to the 1790s. The city center in Cincinnati is showcased by the Tyler Davidson fountain, a bronze statue gifted to the people of Cincinnati in 1881. The fountain and its surrounding square remain a central gathering place for the community. Recently preservation using modern technology has become a new municipal standard for the area.

Situation

When the city council endorsed a community-wide green initiative, the city began to evaluate ways they could improve their energy savings throughout all city-owned properties. Outdoor lighting, especially at Fountain Square, was quickly identified as a source where the city could both save energy and reduce city maintenance expenses. The fountain in Fountain Square utilized more than 65 high-wattage, incandescent flood lights. Aside from the energy drain of these lights, they output a tremendous amount of heat. As a result, the water from the fountain was needed to cool the fixtures. This meant that the display was inoperable during the winter months when the water was drained from the fountain to prevent damage from freezing. Moreover, since the floodlights were located beneath the water, they were prone to fixture corrosion, leaking, and electrical mishaps. Fountain Square needed a robust, long-term lighting solution that was not only energy efficient, but also maintained or improved the aesthetics of the surrounding area.

Solution

When the Cincinnati city council enlisted Eco Energy for this project, we quickly recognized that energy efficiency and aesthetics were not mutually exclusive. We replaced all existing lights with 90w LED color-changing floods with the ability to direct light – using fewer fixtures and less energy. Beyond that, we were able to address both their energy and aesthetic requirements with a single lighting system.

We enabled sixteen pre-programmed shows through the LED displays, changing colors for different seasons, holidays, and events. The LED solution deployed lamps rated for over 50,000 hours of use, capable of generating significant reductions in city maintenance expenses in addition to energy efficiency savings. The LED lights also maintained cooler temperatures so they could be used without the water, and by design, they were protected from leaking, corrosion, and electrical mishaps.
