editor’s NOTEBOOK

Dropped, Not Broken A questions that pops into my head from time to time is, How many times do cell phones get dropped onto concrete or all manner of slop at construction sites?

(I know this seems like a made-up setup for what is to follow, but it’s the honest truth. That question has passed through my strange little mind on more than one occasion. I actually think about these things. I can’t help it.)

I’m confident the extended answer to that question is: More often than you think and the resultant damage to the phones has probably ruined more than one day.

This question revisited me about three months ago when I received an offer to try a Ballistic HC iPhone case manufactured by Ballistic Case Co., Sunrise, FL. I said yes. I wanted to experience the size, bulk, and weight of one of these militarygrade phone protectors. I was also curious about whether, once encased, I would actually be able to use my iPhone.

At least with this product, I have to say, I’m pleasantly surprised. The Ballistic product has a backing case with shockabsorbing “bumps” on all sides and at the corners. The front snaps onto the main case and has a window the same size as the phone screen. For extreme conditions, there is a “gel” jacket that covers everything but the screen.

I had no trouble operating the buttons or plugging in the power cord or headphones. The screen cover does not hinder The Ballistic screen operations in any way. The gel cover has “plugs” that keep HC case puts a dirt and debris out of all ports. Once you encase your phone with healthy shield this thing, you’ll have no doubt that it’s fully protected. of protection Dropping the phone? Yes, I did. I was scared to death, but around the iPhone.

I held the phone at chest height, gritted my teeth, and dropped it on concrete. It wasn’t planned, but it landed on a corner and bounced.

Absolutely no damage.

Bulk? Weight? I carried my phone in the Ballistic case for more than a month. The case is definitely bulkier than my regular phone case and I suppose adds a bit of weight. But I didn’t think it was noticeable and the design offers excellent grip and handling. I quit using it because my soft, pampered life doesn’t place my phone in harsh conditions, but if I were going to spend extended periods at jobs sites or in harsh conditions, the first thing I would do is put it in the Ballistic case.

This is the first time I’ve devoted this space to any kind of a product review but, given what you, our readers, do for a living, I thought it would be useful for you to know of my experience. The company makes a wide variety of cases for mobile phones. Visit their website at www.goballisticcase.com to learn more. The only benefit I received from this venture was a chance to play with the product. You may benefit by saving your phone from complete destruction.

The Green Angle

Energy Market Needs Construction Standards Development of industry-wide standards will drive consistency, efficiency, longevity, and cost savings.

Jelani Rucker, JMC Steel Group

S

olar construction isn’t good only for the environment; it’s great for the U.S. economy as well. The U.S. solar industry provides high-quality employment opportunities for 120,000 workers at nearly 15,000 locations in all 50 states. According to the Solar Energy Industries Association (SEIA), Washington, solar manufacturing will continue to expand in 2013 as a fast-growing, dynamic industry.

A stronger and more competitive U.S. domestic manufacturing base encourages this growth. The U.S. solar industry continues to be a bright spot in the economic recovery, which is why now, more than ever, it’s important to establish industry-wide solar-construction standards that will allow the industry to flourish and reach its fullest potential.

Why the need for solar-construction standards? A major component of the solar industry is the design, manufacturing, and installation of the infrastructure that supports solarpanel arrays. While panel technology continues to become more efficient, infrastructure solutions have evolved at a slower pace. This disconnect makes the case for the solar industry to develop its own set of construction standards to mitigate the customization of each solar project and establish a baseline process.

North America’s increasing demand for green energy and the development of industrywide standards will drive consistency, efficiency, longevity, and cost savings. Solar-construction standards will not only provide cost savings for contractors and solar-parts manufacturers but will allow the industry to innovate and maintain its level of integrity for long-lasting, green-building solutions.

As a whole, the lack of standards in the solar industry makes it difficult for manufacturers to compete in an apples-to-apples market.

Everything is customized or job specific. There is no standard or competitive edge for any project.

The standards for each project are plucked from other applications in which these products are used. However, when those outside standards are applied to solar, they don’t necessarily match up, resulting in product breakdown within 10 to 15 years. That gives the solar industry a black eye. In reality, the solar products aren’t to blame; it’s the lack of construction standards—regulated testing, rules of thumb, installation guidelines, best practices—that results in negative implications for the whole industry.

Let’s take connecting a mounting system to support piers, for example. When there’s no set of standards for these connections or joining methods, how do you build and manufacture a product to support the industry? As a contractor, how do you train your personnel so they know how to install and build the system? As an industry, how do you handle incurring all of the extra cost when every project is custom, which leads to more time and more money for every solar project? It’s not sustainable.

Development D l off iindustry-wide d id standards d d for solar-energy construction would drive efficiency, innovation, longevity, and reduced overall costs.

Identifying the problem Some of the specific obstacles facing the solar industry include: • Design, installation, and construction comprise 50% of total cost. The average cost of a completed PV system dropped by 17% in the first quarter of 2012 compared with the first quarter of 2011.

Overall, the average price of a solar panel has declined by 47% since Q1 2011. This indicates that the installation costs have not declined as fast (Data provided by SEIA.).

• Each solar project is custom. This leaves opportunities for widespread inconsistency within the industry and increases the probability for error, which increases costs. Because permit and licensing requirements vary with the location of the project, inconsistency within the industry (galvanizing or not galvanizing support piers, joining methods for connecting racks to support piers, electrical equipment/wiring solutions) is quite common.

Typical discrepancies that arise during the construction of a PV project include: – foundations not suited to ground conditions – discovery of hazardous or contaminated substances during excavation

Get free product information at www.cbpmagazine.com

– incorrect orientation of modules – insufficient cross-bracing on mounting structures – incorrect use of torque wrenches – damaging cables during construction/ installation.

• All risks are not the same. Reducing any of the risks mentioned above through a warranty has now become a necessity, allowing project managers to combat common objections to solar projects. However, the warranty supplied with support structures varies and may include a limited product warranty of as long as 10 years and a limited finish warranty of five years or less.

What’s more, products used in a solar farm require 20-year warranties on the PV panels. The structures, wiring, and other materials need to work for 20 years as well. Industry standards could increase stakeholder confidence by ensuring longterm viability of solar projects without requiring documentation for decade-long guarantees.

• Solar installations have an increasing impact on the U.S. economy. The SEIA projects that, over the next four years, the U.S. solar market will increase 40%, becoming the largest solar market in the world. With an increasing demand for solar projects, there is an equal pressure to reduce project costs. This balance is difficult to maintain without industry-wide standardization.

These obstacles make a clear case: To keep up with the growth and demand for solar energy, the industry must identify areas of inconsistency and develop concepts for standardizing solutions.

Solar construction standards must exist to ensure accuracy, safety, and proper installation through specific constraints. Standards help to reduce wasted labor and materials. If standards exist, personnel can be trained better and work faster with less downtime and fewer mistakes.

With no standards, there can be no innovation. Consistent quality maintenance and a set of industry standards will put the U.S. at the forefront of innovative green-energy solutions.

feature EDUCATION New lighting in laboratories contributes to a 50% overall reduction in electrical use at Towson Univ., Towson, MD.

Better Lighting A Sparks Better Grades Changes in lighting technology make it easier and less expensive for schools to reduce energy use while providing proper lighting that accommodates a variety of needs.

Tim Hogan, Acuity Brands

ccording to Energy Star officials at the Department of Energy, Washington, the nation’s educational institutions spend more than $14 billion annually on energy. What is even more shocking is as much as 30% of that energy may be used inefficiently or unnecessarily. In fact, the cost of that wasted energy is $4 billion more than what is spent to feed K-12 students in the National School Lunch Program.

In addition to a vast amount of energy consumption, many schools are operating with 50-year-old technology and building standards.

According to the California Energy Commission, Sacramento, in 2006 the average age of California schools was more than 40 years.

However, it is more than aging buildings that is pressuring educational facilities to upgrade.

Schools are faced with rising energy costs and more stringent energy codes and standards, all while overall funding and budgets are shrinking. Additionally, the way of teaching and learning is changing. Thanks to advancements in technology, classrooms today need to be multifunctional to support an integrated approach to teaching, group activities, audiovisual lessons, productivity, and beyond. Schools are using collaborative learning strategies, indoor and outdoor components, and more technology (video projectors, tablet computers, smart boards) during lessons, driving the good old

blackboard to the brink of extinction.

Reducing electricity usage from lighting is one of the simplest things U.S. schools can do to reduce energy consumption, upgrade facilities, and meet the needs of evolving technology. The good news is the lighting industry is changing too, making it easier and more economical to reduce energy use.

The 21st century luminaire Today’s electric luminaires are changing the way we think about lighting. Whether fluorescent or LED, new luminaires deliver superior illumination, improved aesthetics, greater flexibility, and reduced energy consumption. Advancements in LED technology are redefining light fixtures.

Choosing LED solutions expands lighting options, simplifies applications, and enhances capabilities as LEDs, luminaires, and controls evolve. LED sources are known for lower energy consumption and their long life, but the key is really how they can be controlled. Smart luminaires are equipped with plug-and-play controls and lumen-management systems that unlock the maximum potential of LEDs. If a new installation is not an option, there are also LED and fluorescent retrofit kits that can achieve similar results without installing entirely new fixtures. Modern retrofit solutions can deliver superior illumination, improved

aesthetics, greater flexibility, and reduced energy consumption. These kits can replace outdated parabolic or lensed troffers without ever having to break the ceiling plane.

Retrofit kits enable installation of component parts into the housing of old fixtures, maintaining their integrity and delivering the appearance and efficiency of a modern fixture. In addition to better light quality and aesthetics, retrofit kits are installed from below the ceiling plane for virtually no disruption to an organization’s productivity. This is helpful for educational facilities such as colleges and universities that do not close for extended periods of times, or for year-round K-12 facilities.

Clayton State Univ. in Morrow, GA, is one example of institution leadership and facilities directors taking advantage of advances in lighting technology. As part of a gymnasium renovation, the team recognized the need to upgrade their lighting system.

“We were faced with a lighting system that required lots of maintenance for lamps and ballast replacements,” said Darren Thomas, director of facilities management. “And the light levels were too low and uneven for high-level competitive basketball.”

The facilities team studied a number of alternatives and trial installations before adopting the I-Beam LED high bay from Lithonia Lighting, Conyers, GA, for its relighting. The project also benefited from a team that could handle the installation and from a rebate from Georgia Power, based in Atlanta.

The team was able to increase light levels from about 25 footcandles to about 100 footcandles while reducing electricity use. The new lighting system, which meets NCAA Class I performance levels, is a perfect example of reducing costs and improving the functionality of the campus environment.

Schools can achieve even greater efficiency by using natural light. Daylighting delivers efficient lighting with physiological and psychological connections to the outdoors. Skylights, windows, and tubular daylighting systems can capture, transport, and diffuse high-quality natural lighting into classrooms, which helps reduce the amount of electric lighting needed during the day.

“A substantial amount of energy can be saved by using daylight harvesting, but it also can positively influence student performance,” said Zachary Schneider of CMTA Engineers, Prospect, IN, designers of high-performance school buildings. “Studies show bringing daylight into a classroom is a very important component of a successful learning environment.”

Daylighting is always evolving. New tubular daylighting systems networked directly

with controls and electric lighting provide the ability to capture natural light but to also turn it “off,” dim it, and change the contrast ratios to complement electric lighting. The result is a more comfortable and flexible learning environment. Through digitally controlled louvers, tubular daylighting systems and skylights can be controlled to enhance classroom technology such as audiovisual presentations.

Controls for saving energy Smart sensors and controls increase fixture life, increase energy savings, reduce maintenance time and costs, and further tailor lighting solutions to complement classroom needs. Sensors and controls can be paired with electric lighting and daylighting solutions. They can be as simple as occupancy sensors and as complex as programmed control settings for classroom activities that may require different light levels, such as audiovisual presentations and testing. Integrated with lighting and daylighting, they keep the building illuminated appropriately for safety while providing simple control of building lighting, and, ultimately, a better learning environment.

“Controls can offer us many options for energy savings, especially with schools and their schedules,” said Schneider. “When designing a controls system, we evaluate the sequence of operations with the facility. In the case of schools, we can actually shut everything off at 4 p.m., when the teachers leave, and give the janitorial staff an override. We try to get very specific about the lighting controls for maximum energy savings.”

Now more than ever, lighting can be tailored to activities. School facilities can have elementary students in a classroom during the

day and adult education during the evening, easily converting the classroom to support different types of learning.

cost of about $200 to $300 per day, which amounts to more than $100,000 a year,” said Kolb.

The lighting ecosystem Integrated lighting solutions deliver Integration of electric lighting, daylighting, and controls provides a smart and simple lighting solution that improves the learning environment and reduces operational expenses. Whether in libraries, music rooms, science labs, or student centers, an integrated lighting system can meet the needs of students, teachers, and the facility alike.

Take, for example, Towson Univ. in Towson, MD. The school’s energy bills were nearing $10 million annually. An estimated 25% to 40% could be attributed to lighting. In the interest of achieving environmental and budgetary goals, the university decided that cutting its energy consumption was imperative.

For the campus-wide project, the university selected more than 15,000 Lithonia Lighting RT5 fluorescent fixtures in 2-foot by 2-foot and 2-foot by 4-foot configurations, in addition to a number of RT5 fluorescent retrofit kits. The university also installed integrated controls, including occupancy sensors and photocell controls for daylighting.

“Even though we decreased the number of lamps in most areas on campus from four to two with the new fixtures, we actually experienced improved foot-candle levels and achieved better light quality with fewer lamps,” said Steve Kolb, the university’s energy manager. “In most areas, we were able to reduce lighting energy by 50% or more.”

The university expects to meet all original estimates in money and energy savings. “In just the library alone, we have seen an actual reduction in

Creating a better learning environment in a fiscally responsible way should be a key priority in K-12 and higher-education facilities. Quality of light, the return on investment, building codes, and sustainability standards must be key factors in specifying a lighting system.

Light quality is what ensures occupants are visually comfortable. Integrated electric lighting, daylighting, and controls solutions deliver the right kind of light, and the right amount of light, exactly where it’s needed, and only when it’s needed, all at the lowest total lifecycle cost.

Certainly cost plays an important role when selecting a lighting upgrade. Specifiers should think past the initial cost and focus on the total lifecycle cost, including upfront equipment cost and energy and maintenance costs. LEDs, daylighting, and controls are all attainable options for implementing sustainable solutions.

Lighting systems can be compatible with controls that will leverage system performance and reduce the bottom line. These are sustainable, innovative solutions that will benefit schools for years to come and help prepare the industry for the next generation.

proven HVAC technology worldwide, variable-refrigerant-flow (VRF) zoning systems are poised for dramatic growth in all areas of commercial construction. Precise zone control, flexibility, and energy efficiency make VRF systems ideally suited for elementary and secondary schools as well as college and university buildings and residence halls. VRF zoning systems are sustainable, cost-effective HVAC solutions that offer many benefits, including energy savings, increased comfort, design and installation flexibility, lower maintenance costs, and quiet operation. For extra credit, VRF technology offers the ability to capture a significant number of points toward LEED certification.

VRF zoning provides comfort control to buildings with multiple floors and areas by moving refrigerant through piping to the zone to be cooled or heated. Regardless of time of day, sun or shade, season of the year, or special requirements, the systems provide personalized comfort to each room or space, simultaneously cooling some zones while heating others. The systems have many features, including:

Energy efficiency. Because its inverter compressor varies its motor rotation speed and capacity (the indoor units vary their capacity, too), the system precisely meets each zone’s load. Power consumption is reduced because the system operates only at the levels needed to maintain a constant, comfortable indoor environment. In addition, certain indoor units have sensors that compare air and floor temperatures and adjust the output as needed to optimize comfort.

Lighter weight. VRF zoning systems are 31% lighter than chilled-water systems, so they are easier to handle and less expensive to transport. Moreover, the load can be distributed across an existing structure or avoided altogether by mounting the units on the ground.

Lower life-cycle costs. The total installed cost of a VRF zoning system is less than or equal to the total installed cost of most conventional systems. The systems need much less maintenance and require no special trades to change or clean filters and outdoor condensing units.

technology is inherently quiet because it ramps up and down to meet the needs of the space served. Its outdoor compressor is encased in sound-dampening insulation to further reduce noise. Likewise, the indoor unit is designed for quiet performance.

Discreet indoor units. A wide variety of indoor-unit styles offer greater design flexibility. Styles include wall mounted, floor standing (concealed and exposed), and vertical concealed. Ceiling options include suspended, recessed, and ceiling ducted.

Design and installation flexibility. The compact air-source outdoor units, water-source units, indoor units, and other components can be installed in tighter spaces because they require less piping and duct space. They generally include two refrigerant pipes with a non-polar, two-wire control connection, which means faster installations.

Saving money during installation That fast installation, which requires fewer installers than conventional systems, lets schools

save money before the system is even turned on. “Given a tight budget, aggressive schedule, and our primary focus on sustainability, the VRF zoning system was the perfect choice,” said Kurt Haapala of Mahlum Architects, Portland, OR. “It met renovation and new-construction time crunches, such as [installation] during summer break.”

An added bonus is greatly improved indoor-air quality (IAQ) with virtually no pollutants and lower humidity. “Our indoor-air quality is greatly improved—so improved that one student with serious asthma issues was finally able to attend classes in the building again,” reported Lawrence Kicak, manager of HVAC operations and refrigerant compliance at Emory Univ., Atlanta.

n the surface, a school’s mission seems quite clear: to teach, nurture, and educate. Whether it’s an elementary school, a high school, or a university, schools are where students are free to explore and learn about the world around them. The tools needed for a school to be successful also seem rather obvious: teachers, books, and chalkboards, to name a few. But just as important is a safe and secure environment.

Though tragedies of the sort that have shocked the country in recent years remain anomalies, every school must plan for the worst. Government authorities and school administrators are tasked with the challenge of securing students and staff without allowing fear to dictate the atmosphere and attitude of a school. Access-control companies can couple innovative technologies with practical applications to address the needs of many types of facilities, including schools. Yet, until they’re needed, those solutions should not be top of mind for everyday users.

Specifiers for security and life-safety systems need to consider options to protect schools from the start of construction or renovation planning. A secure facility keeps unauthorized individuals from entering the building, protects from dangers within the school, and ensures ready or controlled egress

as necessary. However, each school is unique, and there’s no “one size fits all” security solution.

Despite invariably tight budgets for schools, there are a number of steps architects and school districts can take to improve shortterm security while mapping out a long-term plan. A school’s security system needs to do the following: • control and monitor access with traditional locking solutions and/or access-control technology • quickly secure a classroom from the inside through use of specially designed locksets • provide a safe means of egress from the building.

To accomplish these objectives, companies offer a wide range of solutions, from mechanical locks to networked access-control systems that provide an entire facility with real-time lockdown capability. Specifiers should consult with a certified security professional to ensure that they choose the best solution for the facility.

The basics The first order of business is to secure perimeter doors and critical interior spaces that can serve as areas of refuge, such as classrooms. Start with the fundamentals: • Do all doors easily close and latch?

• How does the existing hardware control and monitor access?

• If a master key and key-control system are in

use, what are the key-control policies?

• Does the key system have procedures to prevent unauthorized distribution?

Any gray areas in the system must be addressed immediately to conform with federal and local codes, including fire codes and the Americans with Disabilities Act. Before selecting hardware, specifiers should determine the best locking scenario for every door in the facility, which can include the following options: • The door remains locked throughout the day, limiting access to a single point.

• The door remains unlocked except in an emergency situation.

• All door locks are controlled from a central location.

Once specifiers identify the operating scenario for each type of opening, they can choose hardware that will achieve that scenario. Many companies’ products were developed specifically to allow teachers and staff to quickly and easily secure a facility in an emergency situation.

Locking up a plan Traditional classroom locks can only be locked by key from the outside. Today’s locks offer several functions that allow the classroom to be secured from the inside, reducing the chance of harm to students, teachers, and staff. For example, classroom-security intruder devices can be locked from the inside or outside and offer the additional assurance of visual indicators when the door is secure.

School systems should consider changing locks that are lockable only from outside to ones that are also lockable from the inside. On the other hand, exit devices should facilitate safe

egress while restricting access from the outside.

Typically used on perimeter doors, panic bars are the first line of defense against intruders.

Exit devices, such as electronic monitoring, can improve school security. An access-control system can monitor many elements, including the latch-bolts and levers, for security breaches caused by doors being propped open or vandalized.

closed, latched, and secured. Another major benefit of an EAC system is that it can provide a complete audit trail for every credential in the system. Records of the activity of every lock are stored in a central database, including which credentials were used to gain entrance and what time the user entered the room.

Building a system The fob is on the job Falling between a mechanical lock and an access-control system, stand-alone electronic locks use a keypad, card reader, or a combination to allow access. A radio frequency (RF) fob, similar to a car remote, is also available to lock down stand-alone electronic locks by pressing a panic button. From as far as 75-feet away inside of the classroom, the panic button secures the door and disables all user credentials to prevent entry by unauthorized persons.

This technology permits everyday access for those with a PIN or credential but secures the classroom quickly in an emergency. Stand-alone locks also provide some advanced features, including audit capability and temporary access codes.

For specifiers in search of even tighter security, electronic access-control (EAC) systems provide it with control and monitoring functions.

Their wired or wireless electronic locks are tied into the master access-control system, permitting configuration of every lock through the main system. Access codes can be changed almost instantly from a central location.

EAC systems also provide monitoring functions that enable precise tracking of anyone who uses a lock anywhere in the system, as well as the status of critical doors to ensure they are

If it is not feasible to add a full EAC system right away, a gradual approach may be helpful, starting with basic stand-alone electronic locks that operate with a keypad or credential to reduce the need for keys and their potential for theft and loss.

Wireless devices that interface with a school’s WiFi system and IT infrastructure are easier, faster, and more cost-effective to install than devices that require a hard-wired connection.

Although the pressure to make sure a school’s security is greater than ever before, it’s imperative to keep in mind that the quick fix may not always be the best fix. Implementing the wrong life-safety and security upgrades can be more harmful than no solution at all. The shortterm benefits of any changes to a system must be considered while ultimately looking at how they will fit into a school’s total security picture, now and in the long term.

ore than 8 million utility customers lost electrical power as a result of Hurricane Sandy’s devastating impact, according to David Sandalow, acting undersecretary of energy and assistant secretary for policy and international affairs, Department of Energy, Washington (see table, p. 24).

He described the storm’s damage during his presentation at the Columbia Univ., New York, Energy Symposium on November 30, 2012—one month after Sandy slammed into the East Coast of the U.S. “Sandy’s impact on energy infrastructure was especially devastating,” Sandalow said. “High winds took down power lines. Rising seas flooded electric substations. Within 24 hours of Sandy’s landfall, more than 8 million utility customers lost power. Fueldistribution networks were paralyzed. Critical terminals for petroleum and petroleum products were badly damaged. Many service stations lost power and couldn’t pump gas, leading to long gasoline lines in the New York/New Jersey area.”

Historically, Bellevue Hospital Center, New York,

has been at the top of the list to receive patients evacuated from other healthcare facilities when disasters— natural or not—strike. However, Bellevue, the premier trauma center in Manhattan, had to evacuate more than 300 patients due to loss of electrical power.

Although the emergency generators, which are located on the 13th floor, were operational, fuel issues prevented their continued operation. According to the New York Times, the fuel pumps that feed the emergency generators are located in the basement at Bellevue, which was still flooded after pumping out 17 million gallons of water. Of course, water and electrical equipment, such as fuel pumps for emergency generators, don’t mix.

More of a guideline Why are facilities that must operate to provide services during disasters allowed to locate critical electrical-system components in vulnerable areas? Although designs of this magnitude require a great deal of thought and planning, it’s difficult to include every

possible scenario. Even codes and standards, as extensive as they are, can’t cover everything.

According to NFPA 110: Standard for Emergency and Standby Power Systems, 2013 edition, Annex A, paragraph A.7.2.4, “EPSS [emergency power supply system] equipment should be located above known previous flooding elevations where possible.”

Also, according to paragraph A.7.2.5, “For natural conditions, EPSS design should consider the ‘100-year storm’ flooding level or the flooding level predicted by the Sea, Lake, and Overland Surges from Hurricanes [SLOSH] models for a Class 4 hurricane.”

The preceding are suggestions from Annex A: Explanatory Material. They are not requirements.

The body of NFPA 110 is less emphatic about flooding. In Chapter 7: Installation and Environmental Considerations, paragraph 7.2.4 states: The rooms, enclosures, or separate buildings housing Level 1 or Level 2 EPSS equipment shall be designed and located to minimize damage from flooding, including that caused by the following:

(1) flooding resulting from fire fighting (2) sewer-water backup (3) other disasters or occurrences.

Note that these flooding references appear in section 7.2.2: Outdoor EPS [emergency power supply] Installations. However, the previous section, 7.2.1: Indoor EPS Installations, doesn’t address flooding at all.

NFPA 99: Health Care Facilities Code, 2012 edition, echoes the language in NFPA 110. However, NFPA 99 is more specific in its Annex B: Additional Explanatory Notes, paragraph B.12.3.2.4: “Flooding into a facility’s lower levels where utilities are often housed results in a disruption of these services.” Paragraph B.12.3.2.5 states, “Power is lost typically as a result of high winds and flooding. Generators and transfer switches have been lost due to their location below the high water mark.” Again, Annex B offers observations and suggestions—not requirements.

NFPA 70: National Electrical Code (NEC), 2011 edition Article 517, is explicit in defining division of a facility’s electrical according to applicability: which loads are essential and which are nonessential. Of the essential electrical system, it defines the equipment system, critical branch, and life-safety branch.

However, as with NFPA 110 and NFPA 99, the NEC does not address flooding in great detail. NEC Article 517.35 (C) states, “Careful consideration shall be given to the location of the spaces housing the components of the essential electrical system to minimize interruptions caused by natural forces common to the area, e.g., storms, floods, earthquakes, or hazards created by adjoining structures or activities.”

NEC Articles 700 and 701 address capacity for emergency systems and legally required standby systems, respectively. “The sizing requirements of 700.4 and 701.4 say that emergency generators have to be able to handle all the loads, but do not apply to hospital generator sets,” said Tom Divine, senior engineer and project manager, Smith Seckman Reid Inc., Houston.

“Hospital generators in particular … have to run for extended periods. For hospitals, you may size according to prudent demand factors and historical data.”

While natural disasters are mentioned in these codes, explicit requirements are not. “The codes are not terribly detailed,” Divine said. “They suggest placing generators with an eye toward a list of possible disasters. But they just give you a list and don’t tell you much. Every segment of the country has its own kind of disasters.”

Location, location, location Do the codes go far enough to enable adequate emergency coverage? Ken Lovorn, president, Lovorn Engineering Associates, Pittsburgh, doesn’t think so.

“They talk about not putting life-safety branch and critical branch wiring in the same raceway [517.30 (C) (1): Separation from Other Circuits]. But they don’t talk about having physical separation that’s distant enough to really prevent a simultaneous outage.”

NEC Article 517, paragraph 517.30 (C) (1) states, “The life-safety branch and critical branch of the emergency system shall be kept entirely independent of all other wiring and equipment and shall not enter the same raceways, boxes, or cabinets with each other or other wiring.”

According to Lovorn, there are some references about having the normal switchgear in the same room as the emergency generator. “But there’s nothing to prevent you from having the generator, switchgear, and the paralleling gear in the basement,” Lovorn said.

“The industry needs more regulation, more codes.

“The location of the electrical equipment should be addressed,” Lovorn continued. “I have encountered many situations where facilities put the electrical switchgear in the lowest level and they get high water, a flood, or a pipe breaks. The electrical equipment ends up getting wet. And water and electricity are immiscible.”

Sandalow’s Columbia Univ. presentation included similar admonitions. “In flood zones, critical electrical

enerators sized to accommodate the anticipated maximum simultaneous load can result in testing problems using a live connected load. Actual building load is often insufficient to test large generators beyond a small portion of the generator’s rated nameplate loading. This situation can cause wet stacking, a condition in which unburned fuel condenses in the exhaust system.

Sizing the generator closer to the anticipated running load averts wet stacking and ensures that the base load exceeds 40% of the generator’s capacity.

However, this creates a scenario where generators have less capacity than desired. One solution is to use load banks to supplement the generator loading during testing. Another solution is to procure multiple smaller generators instead of using a single large unit. Although it requires more capital, this approach solves several issues: generator loading, power system redundancy, and power quality issues.

With a single generator, motor-starting currents, nonlinear loads, and various block loads can affect generator voltage, current, and frequency stability.

However, operating multiple smaller generators on an aggregate bus arrangement is more likely to provide stable steady-state operation, better power quality, unit redundancy, and spare generators, if necessary.

It also minimizes the chance of wet stacking by solving the 40% loading issue.

Hurricane Sandy significantly damaged the region’s fuel-distribution infrastructure. “The Northeast might look to the Gulf Coast for some lessons,” said David Sandalow, Department of Energy, Washington, acting undersecretary of energy and assistant secretary for policy and international affairs. “After Hurricane Katrina, refineries and other pieces of fuel infrastructure were hardened. Some power lines were put under-

ground; backup generators were positioned; in some places, fuel infrastructure was elevated or barriers erected.

Several years later, when Hurricane Ike approached, fuel storage tanks and pumping trucks were pre-positioned in key locations and priority was given to restoring power to the fuel infrastructure.”

“One of the problems with diesel generators: You have to count on them for an extended outage,” said Tom Divine, senior engineer and project manager, Smith Seckman Reid Inc., Houston. “But you can’t always count on the availability of diesel fuel and deliveries.”

Ken Lovorn, president of Lovorn Engineering Associates, Pittsburgh, said the codes “need to have something in place so diesel fuel for emergency generators can be replaced in a timely fashion—even if you have a disaster like Sandy.”

But how much fuel is enough fuel? In the summer 2011 issue of Pure Power magazine, an article titled “Keeping genset fuel flowing during disasters” written

by Robert M. Menuet, GHT Limited, Arlington, VA, said: “Identifying the amount of fuel needed to power your critical equipment during a reasonably predictable natural catastrophe is the first step. A rough consumption calculation for diesel generators is 7 gallons/hour for each 100 kW of generator rating; i.e., a 200-kW generator would consume 14 gallons of diesel fuel/hour. A typical goal for on-site storage is three days worth of fuel. A site requiring a 2-MW generator installation should have approximately 10,000 gallons of available stored fuel to provide a three-day supply.”

After Superstorm Sandy, however, some facility managers may want to increase that supply, at least when a major storm is predicted. Three days can be just the beginning of a long wait for utilities to be restored.

NFPA 110, Annex A, Recommendations For Long-Term Fuels Storage

T

he following text is from NFPA 110, Annex A, paragraph A.7.9.1.2. While this information makes recommendations based on industry best practices, it does not stipulate specific requirements.

To optimize the long-term storage of fuels for prime movers, the fuel tanks should be kept cool and dry, and the tanks as full as possible. Tanks that are subject to temperature variations can experience accelerated fuel degradation, especially if the tanks are outside and above ground or close to an extreme heat source if stored inside a structure. The more constant and cooler the tank temperatures, the less likely temperature-related fuel degradation will occur.

Tank ullage [air space] should be kept to a minimum.

Excess air space allows warm, humid air to enter the tank and condense moisture during the cool evening.

Also, prolonged exposure to ambient air, which is 20%

oxygen, can facilitate oxidative degradation of the fuel.

Fuel storage tanks should be kept as dry as possible and have provisions for water drainage on a regular basis.

The presence of water can lead to microbiological contamination and growth, which in turn can lead to general or pitting corrosion of steel tanks and components, possibly resulting in filter plugging, operational issues, or a hydrocarbon release to the environment.

Regularly scheduled surveillance of the fuel allows the operator(s) to evaluate the condition of the fuel and make important decisions regarding the quality of the fuel dedicated to reliable operation of the prime mover. Fuel maintenance and testing should begin the day of installation and first fill in order to establish a benchmark guideline for future comparison. Laboratory testing services should always be sought from a qualified or certified petroleum laboratory.

equipment such as breaker boxes and building connections should not be in basements or on ground floors,” Sandalow said. “This point may seem obvious, but this basic vulnerability is found in thousands of buildings in low-lying areas. Building codes in general do not address this. In the days and weeks following Hurricane Sandy, water damage to critical electric equipment dramatically slowed electric restoration in many locations.”

“We do a lot of thinking about disasters based on our experience here in Houston with Tropical Storm Allison,” Divine said. Tropical Storm Allison hit in June 2001, dropping more than 40 inches of rain in Texas. The worst flooding occurred in Houston, inundating the city’s downtown area and severely damaging hospitals and businesses.

“I’ve never [personally] had to recover from a natural disaster,” said Divine. “I did a project where we put 2 million sq. ft. in a better situation to cope with a disaster, but it was after the recovery. We took a reference level of 47 ft. above sea level as being the nominal flood plain. The medical center went to 48, and our hospital went to 49. Everybody pushed it a foot higher than the last guy.

“After we picked the nominal flood level, we looked

for anything [electrical] below it that served something above it,” Divine added. “For example, the main service entrance was at about 16 feet. That’s 30 feet deep in water if the 47-foot nominal flood level is reached. We elevated that service entrance to 49 feet. We elevated the second service entrance from 30 feet to 68 feet. We tried to get above what we saw as the 500-year flood plain.”

Lovorn has encountered similar situations. Typically, natural-gas engines are used to operate naturalgas compressor stations. “In this particular compressor station, they decided to put in an electrically driven gas compressor,” Lovorn said. “I went to look at the site and discovered a stream running beside the compressor station. When I learned that the plan was to locate the electrical equipment at the compressor station floor level, I told them it was a really bad idea.

I said, ‘There are no codes that say that I should do or should not do what you’re asking me to do. But I think it’s really poor design, and I suggest that we elevate the level of the electrical equipment to at least the level of the adjacent road.’

a call during a storm from the electrical contractor, who told him that the water was within 6 inches of the floor of the platform for the electrical equipment. “If we had put it down where they wanted to, they would have had 4 feet of water in the electrical gear.”

NFPA 110, Annex A, paragraph A.7.2.4 states, “EPSS equipment should be located above known previous flooding elevations where possible.” But again, this is a suggestion—not a requirement.

Capacity matters While the topic of healthcare facilities quickly comes to mind when disasters strike, other types of facilities, such as police stations, fire stations, emergency-management centers, emergency-call centers, and government facilities, involved in national security are also crucial to public safety and wellbeing and described in the 2008 edition of the NEC, Article 708.2: Critical Operations Power Systems (COPS) as “power systems for facilities or parts of facilities that require continuous operation for the reasons of public safety, emergency management, national security, or business continuity.” Article 708.1, Informational Note No. 1, states, “Critical operations power systems are generally installed in vital infrastructure facilities that, if destroyed or incapacitated, would disrupt national security, the economy, public health, or safety; and where enhanced electrical infrastructure for continuity of operation has been deemed necessary by governmental authority.”

The local authorities can require a designated area—or all of a facility—to comply with 708. If only a designated area, as opposed to the entire facility, is required to comply with 708, that area is labeled a Designated Critical Operations Area (DCOA). Data centers, telecommunications installations, weather-radar systems, and even banking and financial systems are within the scope of Article 708. These services glue our modern society together. While 708 provides a higher level of protection for these mission-critical facilities and services, does it go far enough to ensure capacity?

Article 708.22 (A) states, “A COPS shall have capacity and rating for all loads to be operated simultaneously for continuous operation with variable load for an unlimited number of hours, except for required maintenance of the power source. A portable, temporary, or redundant alternate power source shall be available for use whenever the COPS power source is out of service for maintenance or repair.”

However, 708.22 (B) allows the emergency power source to supply COPS emergency, legally required standby, and optional loads where the source has adequate capacity or where automatic selective load pickup and load shedding is provided as needed to ensure adequate power to (in order of priority): COPS and emergency circuits legally required standby circuits optional standby circuits.

Data-center owners and hospital managers may see the emergency-power capacity issue as a glass that’s either half full or half empty. While some may feel that emergency power must accommodate every load in the facility—even during extended outages—attitudes

tend to change when it’s time to find the necessary funding. However, many data-center owners expend the capital for generating capacity to keep their facilities alive. One reason for this disparity is that data centers have a narrow range of loads—computers, routers, servers, and the HVAC to keep them cool. On the other hand, healthcare-facility loads are extremely diverse, necessitating division and prioritization of loads.

NEC also addresses the duration of COPS operation. Article 708.22 (C) states, “(C) Duration of COPS Operation. The alternate power source shall be capable of operating the COPS for a minimum of 72 hours at full load of DCOA with a steady-state voltage.”

Note that the power-source capacity must be capable of handling the full DCOA load, regardless of whether that designated area is a portion of a facility or the entire facility. Also note that 72 hours is a minimum duration, with no mention of a maximum. Finally, the steady-state voltage must be regulated to within ±10% of nominal utilization voltage, regardless of load.

Telecommunications is another area protected

by Article 708. Data centers must be operational to provide availability. However, operational does not guarantee availability. During Hurricane Sandy, some telecommunications carriers maintained service, while others did not. NEC Article 708 offers the necessary protection.

NFPA 110 Annex A suggests from 48 to 96 hours as a minimum fuel capacity for emergency generators. It also offers suggestions for long-term fuel storage (see NFPA 110, Annex A, recommendations for long-term fuels storage).

Hurricane Sandy affected hospitals and other healthcare facilities, data centers, fuel providers, emergency agencies, and other critical entities. To prevent these vulnerabilities, code-making bodies and authorities must work more closely to ensure the public is protected. While much of the necessary language exists, there is really no widespread infrastructure to coordinate its execution.

“In 2001, our primary customers completely changed their minds about what readiness means [because of Tropical Storm Allison],” said Divine. “We all changed our minds about what a lot of water means.”

Sandalow agreed. “Hurricane Sandy was yet another reminder that disaster response is a complex undertaking that requires sustained partnerships engaging federal, state, and local agencies, the private sector and civil society, academia, and even community clubs and religious groups. Our work together must begin long before disaster strikes. There is always room for improvement, and Sandy has illustrated ways our energy systems are still vulnerable to disruption.” BP

he first of its kind in the western United States, the 45,000-sq.-ft. Virginia G. Piper Sports and Fitness Center, Phoenix, offers a variety of options to encourage healthy, active living for people with disabilities of all kinds.

From a weight room to rock climbing to team sports, the activities at this interactive facility provide clients with a feeling of inclusion from the moment they enter. The addition of colorful, safety-centered flooring from Mondo USA, Conshohocken, PA, brings a “wow” factor to the building, encouraging return visits.

The designers at award-winning Baldinger Architectural Studio, Tempe, AZ, were able to bring to life the vision for this new sports center.

“The entire focus of this project was to create a building that was completely dedicated to people with disabilities,” said Ilan Baldinger, principal. “Often, when sports complexes are built, having facilities or equipment for the disabled is somewhat of an afterthought.

However, at the Virginia G. Piper Sports and Fitness Center, it is the primary goal.”

Accessibility for all meant incorporating hospital-sized elevators and ramps, allowing wheelchair users to travel between the upper and lower floors. An accessible aquatic center

Rubber flooring at a sports and fitness center for people with disabilities handles the unique contact presented by rubber wheels and crutch tips while providing easy cleanup. with locker rooms and shower facilities was crafted to answer the needs of this diverse group.

The design team followed all regulations of the Americans with Disabilities Act to ensure users could enjoy the facilities to the fullest extent.

In some cases, the design team adopted more stringent design guidelines based on actual observation and experience gained from the first phase of the Disability Empowerment Center completed in 2009. “We wanted everything in the center to be as accessible as possible,” said Baldinger.

Safety meets aesthetics The Arizona desert landscape inspired the color palette with beige and terra-cotta as the principal colors. While the tones created a relaxing atmosphere for users of the center, the rubber flooring played a large part in the safety considerations.

“Before deciding on the flooring, we toured several other fitness facilities and realized that Mondo was what we needed,” said Baldinger. “We liked the look of it and Mondo’s reputation for durability is well-known in the sporting industry.

The low-maintenance factor means the cleaning staff only needs to use one product for all the rooms or areas. This results in a cost saving for the center.”

Several styles of flooring were used throughout the building, including Natura in the foyer and common areas, Bollo on the ramps and stairs, Sport Impact in the weight room, and Mondotrack for the 1/10-mile track, which is suspended above the basketball court. Natura was also incorporated into the trainers’ area and used on the front of the registration desk to give a millwork look.

Another reason why Mondo works is that it’s virtually odor-free. “The facility has members who are sensitive to smells. To be truly accessible, the products we used had to be free of scent,” said Baldinger.

The exercise-equipment area has a light birchcolored Sportflex floor with a gray border wide enough for wheelchairs to pass each other, according to Baldinger. This duo-tone design ensures that the heavy machines are only placed on the lighter-colored flooring, which can endure the weight.

Bollo ensures traction on the wheelchair ramps and safety for people using the stairs.

“Bollo is a great product because it has a tactile feeling, so people in wheelchairs know when they are on the ramp,” said Greg Wedge, project manager for Baldinger. “The Mondo flooring holds up very well to traffic, which includes everything from crutches to wheelchairs. Other materials that were used previously, such as carpet, showed the wear and tear and collected a lot of dirt.”

He said easy cleanup is very important when the weather changes. “When people come into the facility and their wheelchair has gone through dirt or wet areas, muddy tire tracks are left on the floor. Simple soap and water can be used for a quick clean.”

With a large variety of wheelchair styles used in the facility, it is essential that the flooring handle the ongoing pressure. “There are several types of wheelchairs, each with varying weights,” said Wedge. “The rugby wheelchair is lighter with slanted wheels. The power wheelchairs are significantly heavier, and we’ve been assured Mondo can take the directional change and other non-linear moves.”

Healing powers of camaraderie The Virginia G. Piper Sports and Fitness Center is not only a facility for members to develop and maintain a healthy lifestyle, it is also a gathering place for like-minded people.

“One of the things that we find very helpful to people who are new to their injuries is peer support,” said Amber Blanchard, manager, who has a degree in therapeutic recreation. “Just like people, all injuries are different. You can’t just give the same exercise prescription for the same injury.

“A lot of times people come in feeling like their life is over and they’ll never be able to do anything again. When they left rehab, they were often sure their life would be limited. Then they come in here and see people with the same type of injuries having a great time playing wheelchair basketball and rugby and rock climbing. They will learn how to adapt the equipment to work with their injuries.”

he first new elementary school in New Mexico’s Bernalillo Public Schools district in 30 years unifies two existing school campuses as part of the district’s reorganization and facilities master plan. Located about 20 miles north of Albuquerque, the new 64,500-sq.-ft. Bernalillo Elementary School was constructed on a compact site next to the existing middle school.

The Albuquerque-based building team included Fanning Bard Tatum (FBT) Architects AIA Ltd, Enterprise Builders Corp., and Southwest Glass & Glazing Inc. The site for the new school was split by an existing irrigation acequia (ditch) that restricted the campus’s buildable area. A two-story facility, however,

allowed a very compact footprint, enhancing the efficiency of the building in usable space and energy consumption.

FBT designed the $10-million elementary school as a high-performance school with building materials and system selection promoting a healthy, sustainable environment.

“Natural daylighting was very important to the design of the school,” said FBT project manager Jeremy Trumble, LEED AP. “Students and teachers were relocated from an existing facility that had very small windows, making the learning environment dark and stuffy, as well as limiting visual access for safety and security.”

The school’s teaching classrooms are

project WINDOWS arranged in three separate wings, corresponding to the three grade levels at the school. According to Trumble, “The library occupies an important corner at the middle of the second level, providing a central access point for each gradelevel wing and offering unrestricted views of the adjacent Rio Grande valley and surrounding vistas.”

Dealing with sunlight Providing natural views and light began with the school’s orientation. “The majority of the classrooms face north or south to help control the direct and indirect sun into each room,” continued Trumble. “Exterior sunshades were added to increase the controllability of the natural light.”

Max/Block sunshades by Tubelite, Grand Rapids, MI, maximize daylighting and minimize solar heat gain from the windows.

These benefits, coupled with recycled content and outside views, are key criteria for projects pursuing certification through the LEED rating system from the U.S. Green Building Council, Washington.

“The extrusions were produced from an industry-leading recycled composite,” said Mary Olivier, Tubelite’s marketing manager.

“Sunshades help significantly lower building cooling costs and energy use, while still letting natural light fill the workspace.” Olivier also noted that the Bernalillo Elementary School’s large expanses of glazing “not only enhance safety and security, but reinforce the transparency of the building.”

Green all over Optimizing strength and thermal performance at Bernalillo Elementary School, Tubelite’s T14000 series storefront and 400 series curtainwall accommodate a wide range of glass options and infills. The curtainwall relies on an exterior screw-applied pressure bar to secure the glass.

The storefront system offers the flexibility of glazing from either inside or outside, which reduces installation time and associated labor costs.

Linetec, Wausau, WI, finished the storefront and curtainwall systems’ recycled-aluminum framing members for the school by applying paint to the interior and clear anodizing to the exterior. This eco-friendly process sends 90% less waste to landfills than traditional anodizing.

It also gives the metal a matte finish, which helps hide small defects in the recycled material and on the aluminum surface of architectural products.

More commonly, painted finishes have been used to coat recycled aluminum. At Linetec, the paint is applied and controlled in an environmentally effective manner to minimize or even eliminate volatile organic compounds (VOCs). The painted and anodized architecturalgrade finishes minimize maintenance and further protect the material under the extreme heat and UV rays of the New Mexican sun, and daily high-traffic use from school children.

ive hundred upperclassmen began the 2012 academic year by moving into a new residence hall at the State Univ. of New York (SUNY)-Albany. Liberty Terrace, a 185,000-sq.ft., $60 million, all-precast-concrete dormitory complex, includes two wings, each five stories tall, with 250 bedrooms in each wing. All apartments include four bedrooms, two bathrooms, a kitchen, and a living/dining area. Also included in the complex is a community center with a fitness center, lounges, and meeting rooms.

With the school’s green tradition in mind, campus administrators chose precast-concrete building systems from Oldcastle Precast Inc., Selkirk, NY, because of a short-term construction schedule, limited construction budget, and energy-efficient attributes, thus maximizing their return by providing excellent life-cycle benefits.

Oldcastle was responsible for the design, engineering, manufacturing, and installation of the entire precast structure.

Precast beams, slabs, and lintels were placed, and hollow core slabs, used predominantly for floor and roof deck components, then spanned from exterior precast wall to interior precast corridor wall.

All of the precast components are integral to the overall structure of the buildings and provide an integrated exterior and interior finish specified by the university.

Jointing the precast exterior wall panels maintains continuous insulation and a fire-rated joint. This was achieved by insulating, caulking, and fire-safing each precast vertical and horizontal wall-panel joint. The interior-corridor precast wall panels had cast-in electrical boxes and conduit where required.

Insulated exterior load-bearing and nonload-bearing wall panels vary in thickness and

provide a steady state R-value of 21.49 and a performance R-value of 28.35, using 4 inches of polystyrene insulation. The exterior insulated wall panels were cast with rigid insulation sandwiched between two layers of concrete with a form-liner finish.

In addition, the interior and exterior precast wall panels were cast with either embedded weld plates or slotted inserts. Welded connections are designed for wind and/or seismic loads and to satisfy structural-integrity requirements.

The precast concrete hollow-core plank, stairs, landings, and beams were manufactured in accordance with Precast Concrete Institute (PCI) Manual 116. All of the precast components were fabricated in accordance with PCI MNL117, PCI MNL-120, and ACI 318 Building Code requirements for structural concrete, Building Code of New York State 2007 Edition, and provisions set forth in ASCE 7-02. Oldcastle crews erected installations of precast-concrete components according to PCI MNL-127 and 135.

project EXTERIORS fully formed. Therefore, no concrete is poured onsite, reducing construction time and significantly reducing the number of on-site workers. On-site waste is also reduced. Incorporating the architecture into the structure enlarges panel sizes, minimizing the number of joints. This prevents water penetration that can weaken a structure and cause unsightly staining and mold problems. The advantages benefit every member of the construction team—especially the owner, whose goals are always paramount.

In terms of energy efficiency, the integral insulating layer of sandwich-concrete wall panels produces several benefits: • superior insulating properties due to the high thermal mass of concrete are unmatched by any other material, including wood and steel, resulting in excellent R-values • no breaks in the thermal protection, compared with wood or steel systems • a thermal mass that reduces daily temperature swings • elimination of air infiltration at joints between panels due to a secure, consistent envelope.

Recognized Innovation and Proven Results Hardcast Spray-Seal Sealed for Life ™

Exterior load-bearing wall panels run longitudinally across the perimeter of the building. Interior precast walls form the building’s corridors.

Assets abound with precast concrete, especially in dormitory settings. Insulated concrete panels can be made moisture-free by sandwiching two layers of precast concrete with insulation, keeping interior temperatures stable while reducing energy costs. Precast panels provide sound dampening between rooms and keep outside noises to a minimum, providing quiet study space. Also, fire endurance is an inherent property of precast concrete. Using precast concrete contains a fire, thus providing sufficient time for safe evacuation.

Green concrete The use of precast concrete allowed SUNY-Albany to realize additional green benefits of precast-concrete construction, including the use of recycled content and locally sourced materials that contributed to LEED credits.

The entire construction project is environmentally friendly in a number of ways. It incorporates features such as permeable pavement, a green roof, rain gardens, daylight maximization, and the use of recycled and locally sourced materials. The buildings are heated and cooled with a geothermal system using the constant temperature of the earth to moderate cooling and heating energy needs.

The university is working with a grant from the U.S. Department of Energy, Washington, for the design and installation of the eco-friendly mechanical system. As a result of the design and the integration of precast concrete with other ecologically safe building applications, SUNY is expecting to attain the Gold level for Leadership in Energy and Environmental Design.

According to the CSTO, the façade re-skinning with Kingspan panels, along with air sealing, reduces Castle Square’s heating needs by 61% and cooling by 68%. The strategy originated with Elton + Hampton Architects, Roxbury, MA; Building Science Corp., Boston; Biome Studio, Boston; Petersen Engineering, Portsmouth, NH; and Pinck & Co., Boston, all familiar with deep-energy retrofits.

Applied to the original brick and concrete envelope with a liquid-applied air barrier and a layer of mineral fiber, the cladding provides an insulation value of R-41, twice what current codes require. The 5-inch panels accomplish the DER’s enclosure goals while furnishing the building with its beautiful and durable new facade. The insulated metal panels solved several challenges at once: adding exterior insulation and air barriers to greatly improve thermal comfort, allowing residents to stay in their homes during construction, and achieving a sleek, modern look that pleased residents and neighbors alike.

“Tenants tell us they’re now very proud of the multifamily building’s look,” said Kingspan’s Bertram. “But more importantly, the residents now tell us that they feel more comfortable and healthy, and their energy bills are coming down.”

Other benefits of the deep-energy retrofit continue to accrue. The retrofit construction work for the project created more than 200 jobs. The project was partly funded by the 2009 American Recovery and Reinvestment Act stimulus through the Massachusetts Department of Energy Resources High Performance Grant Program, as well as through the U.S. Department of Energy and Department of Housing and Urban Development, Washington, Green Retrofit Program.

In addition, the U.S. Centers for Disease Control and Prevention, Atlanta, have been studying Castle Square and other projects around the country to measure the effect of energy retrofits on air quality and, in particular, asthma rates in residents.

One brand.

One source.

One solution.

ClimateMaster® delivers complete water-source or geothermal heating and cooling solutions for every segment of the commercial construction market.

Because we can provide all the components required for most applications, you are assured a perfectly matched, perfectly controlled, perfectly installed system.

1. All the Heating and Cooling Required.

A ClimateMaster® system will provide both heating and cooling to the building, changing modes based on the building load. Heat can even be transferred from one part of the building to another. A single control system will manage all these functions.

You’ll need less equipment and have a completely integrated system.

4. vFlow™ Variable Water Flow. vFlow™ variable water flow technology represents a major advance in system performance. vFlow™ not only builds the major water circulation components into the unit for a clean installation, it also intelligently varies the water flow to minimize energy consumption and improve system reliability.

Get the entire ClimateMaster® system story by calling 1-877-436-6263 to connect with a ClimateMaster® Commercial Representative.

2. Multi-Protocol DDC Controls.

Factory-mounted Direct Digital Controls lower installation costs by reducing problematic on-site wiring. Implement a variety of building automation protocols through a PC, and read fault codes from any remote location.

3. Energy Recovery Ventilator.

Improved IAQ is achieved with an ERV, coupling outdoor air treatment directly to space conditioning equipment. Stand-alone and mated rooftop configurations are available to meet your design requirements.
