Pike Research, a global consulting firm, has issued a new report noting that global revenues from building energy management systems are expected to rise almost 14 percent, year over year, through the end of the decade.
The term building energy management systems, or BEMS, refers to computer hardware or software systems which connect to, monitor, and regulate mechanicals like heating, air-conditioning, lighting and mainframes, or other operations that use energy. Building energy management systems can also be used to monitor water and other resource uses.
According to Pike, this means that actual revenues from BEMS are expected to reach slightly less than $6 billion by 2020 – a hefty sum even in what economists have predicted will be a "shrinking" economy. The information, available at no cost from a press release (and in-depth from a very costly report), highlights the expanding building energy management vertical within the building energy efficiency/LEED/EnergyStar marketplace.
LEED, or Leadership in Energy and Environmental Design, is one metric construction engineers and building efficiency retrofit firms use to certify their structures. These certifications are based on different parameters whether the building is new or old, but come in four categories: Platinum, Gold, Silver and Certified.
Operated under the auspices of the U.S. Green Building Council, or USGBC, LEED ratings represent what some feel is the "best of the best" in terms of building sustainability, since they measure across a broad spectrum: site sustainability and feasibility, water use, energy use, sustainable materials use, indoor air quality, and innovation in design, and encourage both awareness of and education regarding "green" building initiatives.
Energy Star, a building energy efficiency rating program operating under the guidance of the U.S. Environmental Protection Agency, or EPA, and the U.S. Department of Energy, or DOE – and representing an offshoot of the Energy Star appliance energy efficiency certification program – is another system which builders and remodelers use to achieve "green" building status; that is, Energy Star-certified buildings use less energy, produce fewer greenhouse gas emissions, and are less expensive to operate.
Building efficiency and sustainability are gaining increasing exposure as a perfect storm of rising energy costs, reduced energy supplies, U.S. energy security and the environmental movement all converge, with the help of Information Technology, to address issues never before so completely under the control of building managers.
Also known as Smart Grid innovations, or building automation, these IT innovations are helping to curb the vast amount of energy used by commercial buildings – an energy expenditure which was highlighted by President Obama in his 2011 budget proposal, which provided $28.4 billion for DOE policies, including mitigating environmental (climate) risk and maintaining national security.
Elsewhere, wireless sensor networks and software building energy management tools, being developed both in government laboratories and in private companies like Scientific Conservation, Inc. are also saving cash and energy in U.S. buildings, and this perfect storm couldn't be happening at a more perfect time, given a decision by Obama to boost energy efficiency in government buildings by nearly $4 billion between 2012 and 2014.

Hit Efficiency Out of the Park with Advanced Lighting Control
Energy efficiency is potential opportunity residing in commercial building systems. If tapped, it is profit that grows annually as energy prices rise. Yet for as long as this opportunity is left untapped, it becomes more costly to implement.
In October 2009, the average cost per kilowatt-hour was approximately $0.10 for commercial buildings, 42 percent higher than the average for the year 1999. Typically the largest and least controllable load in a commercial building, lighting accounts for 20 to 40 percent of the average business’ electric bill and 25 percent of an average building’s total energy use (including electricity and all other fuels).
A large portion of this rising cost is avoidable. According to the Lawrence Berkeley National Laboratory, about $130 to135 billion, or 57 to 59 percent, of the some $230 billion annual cost of global lighting could be saved by using commercially available energy-efficient lighting technologies – with 25 to 40 percent of those savings achievable in the commercial sector.
Within this context, advanced lighting control provides a platform able to accomplish a broad spectrum of integrated strategies for the purpose of energy management, such as smart time scheduling, occupancy control, load shedding, daylighting control, task tuning and personal lighting control. Good systems are simple to design, install and use. They adapt to future needs and lend themselves to both retrofit and new building applications.
Considering that November is the month the sports world completes its seasonal transition from baseball to football, this is an opportune time to focus on a case study involving the implementation of advance lighting control in a high-profile stadium – namely, Rogers Centre in Toronto, Ontario.
Employing a customized approach, the advance lighting control system at Rogers Centre was designed to accommodate needs and usage in a number of distinct areas. For example, in the parking garage - where the lights previously had not been switched off in 18 years – it provided for occupancy sensor based switching control on a zone basis. Additionally, the eight-foot, T12, 96-watt lamps were changed out with two, four-foot T8, 32 watt lamps and electronic ballasts.
In the concourses and stairway areas, a combination of occupancy sensing and time-scheduled switching (based on building events) was employed. The existing, 175-watt metal halide fixtures were retrofitted with two, 32-watt T8 lamps and standard electronic ballasts.
All office areas and lounges were equipped with personal lighting control, time scheduling, daylight harvesting and occupancy sensing technologies. Additionally, all existing fluorescent fixtures were retrofitted with new dimming electronic ballasts. The approach in the luxury boxes involved control of lighting and television circuits by time schedule, based on Rogers Centre’s scheduled events.

LED Spotlight With Ergonomic Handle
Designed to operate on a variety of voltages ranging from Capable 9 to 48 Volts DC simply by connecting the unit to a suitable power source, this industrial grade spotlight is equipped with a solid composite plastic handle with an ergonomic design for easy handling and a sure grip. Connection to power sources includes a variety of optional cords including 16 and 25 foot straight cords with cigarette plugs, a 21 foot cord with battery clamps, and a 16 foot straight cord ending in battery ring terminals or a cigarette plug. A single heavy duty tension hinge connects the lamp to the handle, and the lamp housing is constructed of heavy extruded aluminum for serious durability.
The LED and reflector assembly is protected by an unbreakable shatterproof polycarbonate lens and produces a tightly focused light beam reaching over 600 feet in length. Unlike other LED spotlights, the LED and reflector assembly on this unit produces a very tightly focused light beam with little of the spread or wide angle fade of other similar units. The LEDs in this unit are rated at 50,000 hours of life expectancy and run cool enough to touch during operation, removing the possibility of the accidental burns associated with incandescent lamps.
This LED spotlight is IP68 rated waterproof and dustproof and will withstand full submersion in water up to 3 meters, making it well suited for marine applications. The high output, low power requirements, and extreme durability and versatility of this LED spotlight makes it ideal for security, law enforcement, hunting, and cable/power/utility work applications where operators need an effective and well focused light source than can run for extended periods without draining a vehicles batteries.
“The HL-7LED-3C is a very tough, durable LED light with a focused spot beam,” said Rob Bresnahan. “This LED light with a cast aluminum head and watertight construction can be used for inspection in and around boats, vehicles and heavy equipment. You can drop this LED light into 3 feet of water, pick it up and get back to work. Plus, this handheld LED light is cool to the touch and can run 24/7 for 5.5 years straight without needing a bulb change. We really see this as a lifetime 12/24 volt LED work light that is completely maintenance free.”
Magnalight by Larson Electronics carries a wide array of LED spotlights, Law Enforcement spotlights, LED light bars, 12/24 Volt LED lights, and industrial grade work lights, and offers a comprehensive selection of the latest in industrial/commercial lighting technology.
