Keeping The Old Ones Alive As a photographer, one of my favorite things to do is photograph old buildings, such as the one shown here from the Soulard district of St. Louis. Old buildings have that extra something that is rarely seen in “modern” architecture. I don’t know what that “something” is, but I sure enjoy looking at it.

On the opposite side of that coin, I always feel a twinge of sadness when I see old buildings being destroyed to make room for the replacement of the day, be it a parking garage, park, skyscraper, or strip mall. (Don’t we have enough of those strip mall things?) My first thought is always, “Can’t we find a way to keep that old building, fix it up, and put those old ‘bones’ back to work?”

That’s why I enjoy hearing and reading about renovation projects, the primary subject of this issue. Today’s renovation environment is exciting because those involved are doing so much more than replacing windows and slapping on a new coat of paint.

As author Chris Sullivan points out in our lead feature (“Research Maximizes Renovation Projects,” p. 8), leading architects are taking a much broader view of renovation projects, doing some research, developing a thorough understanding about what a client needs, and renovating buildings so that they Old buildings, such as this one in the Soulard district of St. Louis, have a deliver a much-improved work environment, character that is rarely evident in save energy, and provide features that often modern architecture. the client doesn’t realize he/she needs. They are truly making those old bones live again.

I also enjoy the way technology is making it possible to keep that old look while providing needed amenities. That is particularly evident in Jayson Drake’s article about renovating the Mayo Hotel in Tulsa, OK, (“PEX Pipe Big Factor In Hotel Renovation,” p. 20). Were it not for the many advantages of PEX piping, renovating that historical structure would have been extremely difficult, much more expensive, and likely at the price of much of the original character. The renovation also might have never happened and another beautiful structure would have been lost forever.

There are lots of great old buildings that, with just a little effort, could be restored to their original beauty while providing the energy efficiency, indoor air quality, and creature comforts that we all would like in a work environment. I hope we continue this renovation movement so that the old buildings can shine once again.

The Green Angle

Analyze Before You Illuminate With LEDs Lighting a space with LEDs generally results in energy savings, but realizing maximum bang for your buck requires a little homework.

Brett Shriver, Global Lighting Technologies

T

he benefits of LED lighting are wellknown—no radiation, no flicker, long life, energy savings, instant on, no tubes to replace, and no ballasts to fail. The hazardous waste that accompanies today’s conventional light sources, such as the mercury in fluorescent and high-intensity-discharge lamps, is eliminated. However, replacing conventional lighting with LED fixtures is not necessarily a straightforward project. To realize maximum benefit from the technology, several factors must be carefully considered.

For one, what’s the ROI? That depends on the scale of the retrofit and the technology used. We retrofitted all of the spaces in our 16,000-sq.-ft. facility with LED fixtures. We used 2 x 2-foot downlights in the areas with a 2 x 2-foot ceiling grid, and 1 x 4-foot lights in the areas with a 2 x 4-foot grid. Since completing the retrofit in November 2012, our monthly kW usage has dropped from 896 to 303, and our electric bill has dropped by more than 65%. Actually, for lighting alone, excluding any other source of electricity consumption, our savings are in the 75% to 80% range. Based on our experience, ROI is approximately 18 to 24 months, at the most. Plus, there is additional ROI from providing employees a more pleasant working environment that has more attractive lighting with significantly less glare.

The cost What’s it going to cost? There is always a tradeoff between efficiency and cost. Component reliability and lifetime are also key issues. LEDs vary in price, and cheaper is not necessarily better. You’ll also be using power supplies, which last much longer than ballasts, and if you source good ones, they’ll eliminate the failures that are inherent with ballasts, not to mention the expensive visits from the electrician. Overall, on average, energy savings are around 75%, compared with a fluorescent system.

Another consideration: How much

are the lights on? The longer they are on, the more you save. An extreme example is a casino, where the lights are in use 24/7.

In this environment, LEDs are a no-brainer.

The dimming capabilities of LEDs darken gaming tables not in use in the wee hours of the morning. Hospitals also benefit from this capability by dimming areas not in use during nighttime operation. This maintains a more genial atmosphere and makes hospitals more, well, hospitable. LED lighting in schools provides a more comfortable atmosphere for learning, another example of ROI you can’t quantify but is nonetheless genuine.

Another option is occupancy and daylight sensors that will turn the lights on or off depending on whether anyone is in the room or if ambient light coming through the windows eliminates the need for artificial lighting. LED lighting can also be designed in a variety of sizes and colors.

Ask for the specs. What is the expected lifetime of the fixtures? 30,000 hours or better? Are they easy to install? What about a warranty? A reputable manufacturer will warrant its downlights for 2 to 5 years. What kind of technology are the fixtures using, and how efficient is it? Are they illuminated by LED arrays or LEDs spaced along the edges of a light guide, which typically uses fewer LEDs, lowers part count, and increases energy efficiency?

What about the optical performance? How uniform is the lighting?

LEDs, despite all of their advantages, do generate heat, which is emitted from the back of the unit. This problem requires a cooling solution, either active or passive, to properly dissipate the heat and ventilate the fixture. An adequate thermal heatsink solution to ventilate an LED system is vital for every lighting installation, especially recessed troffer/ceiling light fixtures. Watch out for high junction temperatures that can degrade LED performance. Every chip manufacturer tests and can provide junctiontemperature ratings for each of its products.

Power dissipation indicates the amount of power wasted as heat by a given device.

That is normally what is meant when an LED fixture is given a maximum power-dissipation rating. A power-dissipation rating of 46 W from an input of 100 to 240 VAC indicates low power consumption and high efficiency.

As always, comparison shopping pays off. Make sure the components and materials provide good efficiency, have the UL label, use long-life LEDs, and incorporate good-quality power supplies.

Energy savings with LEDs are around 75% compared with fluorescents.

Features to seek, mistakes to avoid There are a number of errors and oversights to avoid. Number one is selecting the wrong vendor. If you’re outfitting a commercial building, you need an electrician to perform the installation. Make sure you hire reputable contractors who use good-quality LED fixtures, are experienced, and charge a reasonable rate.

Installation should be relatively easy for a true professional.

Don’t overpay. Be cautious of companies who say they will work with you to get grants and tax breaks from the government and then double the markup on the lighting fixtures and components. Don’t base your decision on cost alone without considering the quality of the components, particularly the LEDs and power supplies, which are the two main causes of failure. There’s a lot of poor quality out there, so caveat emptor applies.

feature REHAB/RETROFIT CONSTRUCTION

Research Maximizes Renovation Projects Taking time to understand the owner’s business and goals for a space often results in a renovation project that does much more than simply upgrade equipment.

Chris Sullivan, C.C. Sullivan

T

he renovation universe comprises a wide variety of project approaches that span a spectrum from mere product replacement at one end to major reconstruction—additions, expansions, and other structural reconfigurations—on the other end. Yet even one of these categories involves quite a range of options: A product changeout can be relatively minor, for example, such as swapping LED lamps for existing halogen or incandescent bulbs, or it can be as extensive as a roof replacement, requiring new insulation board, waterproofing, membrane, and ballast.

Retrofits, which typically describe a system changeout (the roofing example straddles the line between replacement and retrofit), contrast with building renovations, which tend to be extensive, multi-system projects such as a gutrehabilitation of an old office building.

All of these terms describe the removal of existing building components and installation of new products and systems. The more complex and extensive the project, the further along

the spectrum it moves, where the designand-construction teams are bigger—and the bills can make owners turn pale. Toward the more-complex end, there are also more code considerations and regulatory hurdles to address.

Each project approach has its place and time, says Layng Pew, AIA, managing principal for WXY Architecture + Urban Design, which recently renovated a major museum in the firm’s home town of New York, adding a Drawing Center in the process. “It’s important not to take a boilerplate approach to project planning or material and system selection, which can cause you to miss opportunities,” he said. “The first step for us is to understand where the client is coming from and how they want to grow.”

Know the owner’s goals Some rules of the road may apply to any situation, experts agree. Replacement projects, for example, are meant to be tactical, simple, quick, and cost-effective, but in reality they may suffer from a lack of experienced oversight. Too often

they are driven by a single product vendor or specialty contractor whose sole aim is to make a sale. Of course, the seller may have the requisite knowledge to handle the work, and if the owner offers competent oversight of the project, it should all turn out fine.

Joshua Zinder Architecture + Design (JZA+D), Princeton, NJ, is currently leading selective renovations of 506 Carnegie Center, a building in a commercial office complex in Princeton owned by Boston Properties.

“For institutions and other owners that occupy or otherwise retain their buildings for the long term, any replacement project offering a good return on investment or life-cycle cost is worth consideration,” said Marlyn Zucosky, IIDA, partner and director of interior design at JZA+D. “Whether it’s durable flooring or LED lighting, we can review the ROI or conduct an LCA [life-cycle analysis] to weigh the costs and benefits from installation through the disposal, recycling, or reuse of the products at the end of their useful life.”

As an example, New York architect Lee H.

Skolnick, FAIA, describes the high ROI of signage and exhibit replacements, where everything from informational displays and entire museum installations are swapped out to better support the building-owner’s core mission. The same is true of educational presentations that reflect a school’s curriculum or a manufacturer’s product line, or a brand-boosting showplace simply meant to pull in more traffic to a cultural landmark.

For the Mohonk Preserve Visitor Center in New Paltz, NY, which reopened this spring with new signage, a topographical display, touch table, and other exhibits, the design team at Lee H. Skolnick Architecture + Design Partnership, New York, also adapted the gift shop for reuse as an orientation theater and added a handicappedaccessible sensory trail. “As opposed to schools, which tend to be curriculum- and standardsoriented, when you are developing highly interpretive exhibits and interior environments, a key to determining whether the investment is worthwhile is knowing the audience,” noted

Skolnick. “Research on their needs and interests allows us to create the best entry points for getting the visitors engaged with the subject matter.”

This market orientation is common among even institutional projects and a major driver for replacement projects and full renovations alike.

Beware conflicts of interest While product replacement may be undertaken by the sole vendor or by in-house facilities’ staff, system retrofits by definition tend to require design guidance by an architect, engineer, or specialized consultants, or a mix of these professionals. In some cases, the manufacturer of a retrofit system may offer in-house engineering and expediting of approvals at a relatively low cost.

For the energy retrofit market, the role of the 100 or so U.S. energy service companies (ESCOs) registered with the Department of Energy, Washington, has been a double-edged sword for building owners. ESCOs typically aim to provide an energy-saving upgrade opportunity with minimal capital investment. Anticipated energy

At The Drawing Center in New York, a museum specializing in works on paper, the firm WXY added 50% more gallery and programming space and a sophisticated lighting scheme that combines natural light and new, non-UV-emitting LED fixtures.

Joshua Zinder Architecture + Design (JZA+D), Princeton, NJ, is currently leading selective renovations of 506 Carnegie Center, a building in a commercial office complex in Princeton owned by Boston Properties.

The flexible, new spaces of the W-B 24 scientific research hub for Yale Univ.’s growing West Campus accommodate the newly formed Nanobiology Institute and its study of cell biology and biophysics.

The renovation project provides a strategic modular platform for customization to the unique needs of these recently announced interdisciplinary research groups.

The Mohonk Preserve Visitor Center features a topographical display, touch table, and other exhibits. The design team at Lee H. Skolnick Architecture + Design Partnership also adapted the gift shop for re-use as an orientation theater and added a handicapped-accessible sensory trail.

reductions are used to finance the new products, systems, engineering, operations support, and often even a warranty. That’s good news. But on the downside, many of the ESCOs are affiliated with utilities or product manufacturers, so they have a strong incentive to load up the retrofit with the product brands and fuel types that make them money, whether it’s lighting, HVAC systems, solar panels, or liquid natural gas.

Still, energy retrofits are a fast-growing segment of the renovation universe, and projections by research firm SBI Energy, Rockville, MD, show that by 2015 as much as 15% of the total market could be driven by upgrades to building MEP (mechanical, electrical, and plumbing) systems. The benefits of energy retrofits, however, depend heavily on proper operations and maintenance practices following the work.

Energy retrofits are only a fraction of the market for sustainability-focused green renovations. The trend took root in utility incentives for demand-side reductions and later the 2005 Energy Policy Act, which provided large

feature REHAB/RETROFIT CONSTRUCTION tax breaks for investments in energy-saving technologies. Then the 2007 Energy Independence and Security Act gave added impetus to the use of renewable energy systems.

The greenest renovations According to Michael Binette, AIA, NCARB, and principal of The Architectural Team, Chelsea, MA, in some projects it’s possible to recycle on a very large scale—redeploy entire buildings, existing materials, structure, and MEP systems—saving money and resources in the process.

Some of these adaptivereuse projects for historical factories open the door for adding modern cogeneration systems or even reviving hydroelectric capabilities. They can also accommodate renewable energy, using their large, flat roofs to support new photovoltaic panels and solar thermal collectors and by drilling geothermal wells below. Existing buildings usually can be reconnected to the grid more easily than most greenfield sites, too.

“When evaluating the best gains, look for simple answers first,” Binette said. “We work often with historic mills, where new insulation offers the biggest benefit at the lowest cost.

We have achieved thermal barrier values as high as R-23 with medium-density spray foams in combination with cellulose insulation on century-old masonry structures.” One such case was the Oliver Lofts in Boston, an adaptive reuse, mixed-income residential property that was formerly a brewery warehouse.

The return on energy-related upgrades is well established. For green buildings and sustainability retrofits, there is a growing body of information underscoring the financial benefits of upgrades focused on occupant health and well being, lower toxicity, and occupant productivity.

One study of hundreds of LEED-rated buildings by the Univ. of San Diego and the real-estate data company CoStar, Washington, showed rents increased by more than $11 and resale values jumped more than $170/sq. ft. for green buildings, compared with their non-green neighbors.

This value can be captured for long-term property holders, too. For example, the Haverford School, Haverford, PA, undertook a $28-million restoration and expansion for an upper school and administration building to meet the educational needs of information-age students within and adjacent to a historical 1903 hall. The 10

with a visioning session in the earliest part of the planning phase to establish a description of a futurestate based on shared values among the various stakeholders,” Brotman explained.

For WXY’s work on the Drawing Center, the client’s planned expansion strategy led to a feasibility study. The cultural group had long considered a highprofile new building at the World Trade Center site, and compared that with another site several blocks away.

The museum leadership eventually decided to stay at its existing, and iconic, location, said Layng, based on the favorable ROI of an extensive renovation including new gallery interiors, MEP systems, skylights, and stairs for the 19thcentury loft building.

Behind the decision was a careful accounting of organizational needs and longterm vision, followed by a detailed analysis of design options and associated costs. “From these granular details come the inspiration and foundation of truly great projects, where their unique attributes fully serve the core of each organization’s goals,” said Brotman. “But this is only the case if the planning phase has thoroughly nurtured these granular details to generate something larger from them.”

Kelley of MGA Partners, a firm that has expertise in university live-learn environments, agreed. “Often our challenge as the architect and planner is to help shape a new organizational system while adapting physical spaces to accommodate how they work.”

The many different approaches to successful renovation boil down to extensive planning that involves everyone with a horse in the race. That key element, however, may be just about the only thing any given group of renovations has in common. As the saying goes, if you’ve seen one renovation, you’ve seen one renovation.

Each project brings enough challenges and opportunities to keep the entire team on their toes for the duration.

For the Haverford School, MGA Partners restored the 1903 Wilson Hall, designed by noted architects Fred Furness and Allen Evans, and paired it with a sophisticated modernist expansion for a major new academic building certified LEED Gold.

JUL/AUG 2013

LEED Gold landmark facility is also a teaching tool for environmental responsibility, according to Daniel F. Kelley, FAIA, senior partner with MGA Partners, Philadelphia, and lead designer.

“The project incorporates many strategies to minimize the building’s carbon footprint and create a healthy environment for learning,” said Kelley. “It has launched the school’s heightened commitment to sustainable practice across campus.” One example: an array of specialized meters and controls that give students and teachers real-time feedback on energy and water usage.

More than mere looks Other retrofit and renovation projects are geared toward aesthetic and performance upgrades, such as exterior recladding and overcladding. A number of school districts and healthcare providers are adding continuous exterior insulation, or CI, to existing buildings by overcladding. In addition to a renewed look, it’s an effective technique for improving acoustics and the effective R-value while controlling condensation and air infiltration.

Yet some renovation approaches don’t work well. In many cases it’s because the old building can’t support the kinds of renovations envisioned, leading to costly added work. But usually projects fall short of expectations because the goals and the design vision are out of alignment, said Jay M. Brotman, AIA, a partner with the architecture firm Svigals + Partners, New Haven, CT. “We use a process of lab planning called Phusion that is ideal for these complex renovation projects,” said Brotman, who recently led the transformation of a corporate complex in New Haven, into the W-B 24 scientific research hub for Yale Univ.’s growing West Campus Integrated Science & Technology Center. “Phusion begins

The demand for blast-mitigation products is increasing in new and retrofit building applications, giving architects a unique opportunity to safeguard human lives.

Determining which fenestration solutions and systems to specify for blast mitigation is a formidable responsibility. Making the right decision lies in understanding how the products are produced and what they’re designed to do.

Developing high-performing blast-mitigation solutions involves several interdependent steps to ensure the effectiveness of the products.

Step One: Understanding Blasts.

According to the Oxford Dictionary, a blast is “a destructive wave of highly compressed air spreading outward from an explosion.” Hazards resulting from a blast include flying glass shards, building components, shrapnel, dirt, rocks, and debris, leading to possible structural damage and/or building collapse. Fenestration

products cannot provide complete protection from an explosion, but in the unlikely event of a blast in or near a building, products designed to address blast hazards can help reduce the damage.

When looking at the nature of a blast there are two elements to understand: the charge weight and the standoff distance. The charge weight is the amount of explosives used (TNT equivalent), while the standoff distance is the distance of the point of detonation from the target. Ultimately, the greater the standoff distance, the slighter the explosive threat to the building or target.

Step Two: Assessment and Testing.

According to the American Architectural Manufacturers Association (AAMA), Schaumburg, IL, the conditions for blastmitigating fenestration systems include limiting flying shards, glass preservation, frame support, and wall integrity. These criteria are all taken into consideration during product evaluation.

The first step to any blast-mitigation project is a thorough threat assessment by a third-party consultant to determine the estimated size and nature of the potential explosive device, as well

as the standoff distance. The consultant will evaluate issues such as the likelihood of an attack and how close a vehicle or carrier can get to a building. Risk-analysis software and site surveys help blast consultants determine the answers to those questions and more. Whatever the method, this step is critical and the results must go to the design team as the foundation for the project design.

After the initial threat assessment, several test methods that simulate the effects of an explosion can measure blast resistance. These methods include: • Static testing, an economical method that employs the conventional static-testing methods used to test fenestration products.

• Shock-tube testing, a moderate-cost method that uses a compressed-gas charge or a live explosive device to achieve the positive pressure of an explosion. However, this kind of test usually lacks negative-phase effects.

• Open-air arena testing in which an actual explosive charge is positioned at the projected standoff distance. The most realistic and costly method, it produces positive- and negative-phase blast effects.

The blink of an eye The blast duration of a large explosive device is typically in the range of 28 to 42 milliseconds, which is roughly an eighth of the time it takes for an eye to blink. Destruction can vary greatly based on distance and the size of the explosive, so thorough testing can provide vital insight.

The shock-tube and arena-test methods use a number-zoned “witness chamber” to help measure the effects of debris entering the room as a result of the blast. The performance of the glazing system is determined and given a performance condition or hazard rating relative to the testing standards.

Building blast-resistance requirements, known as blast mitigation standards (BMS), are driven by the size of the explosive device and distance to the target. The BMS is typically expressed in pounds/square-inch•milliseconds (psi-msec) of reflected pressure and psi-msec of impulse. Without these elements, the BMS is incomplete and the building is likely to be inadequately protected.

During this process, testers evaluate the building and wall assessment/reinforcement, addressing design and product options as

well as the blast resistance of the products and attachment methods. The evaluation and assessment must look at the products as a system and examine how the various elements work together. Key factors to consider include: • The glass can break but cannot send flying shards into the room.

• The glass lite must stay in the frame, along with all interior window components.

• The frame must remain anchored to the wall.

• The wall must resist the load and retain the frame.

Depending on building and construction methods, materials, and construction, several wall-anchoring options are offered: • Basic trim and clip, usually suitable for lowblast-load applications • Expansion and adhesive anchors • High-performance grout-filled anchors, particularly effective in retrofit applications where support for high blast loads requires tying together unrelated construction elements or deep anchoring.

Highly skilled glazing contractors and window installers are essential to the overall process and critical to assuring proper

Step Three: Security Criteria and International Standards. Today the design process for most government and military structures must take blast demands into account.

More and more, the education sector is also considering them. In addition to assessment and testing, architects are required to specify products that meet certain government and international standards. While no criteria or testing methods can promise total protection from explosions, government agencies designed these standards to consider the effects of explosive events on their facilities and offer steps to mitigate the extent or probability of damage.

Three common standards are: • Security criteria by the Interagency Security Committee (ISC) and the General Services Administration (GSA), both based in Washington.

Initially established to address glazing in all federal buildings after the bombing of the A.P. Murrah Federal Building in Oklahoma City, the GSA security criteria resulted in the increased use of blast-resistant fenestration products in federal courthouses and similar government buildings.

The ISC took it further by developing its own security criteria, which were approved for use in all new GSA buildings and major renovation projects. These criteria, intended to reduce potential hazards, require that windows be designed to mitigate the risk from flying glass fragments in the case of an explosion. These measures were designed with the understanding that not all fenestration products will survive a blast.

• ASTM International Standards: Similar to the ISC/GSA performance, West Conshohocken, PA-based ASTM International’s ASTM F 1642-04 Standard Test Method for Glazing and Glazing Systems Subject to Airblast Loading establishes a testing method that evaluates levels of protection. These criteria require that glazed-window products meet performance levels that correspond to specific levels of protection.

• Department of Defense (DoD): The Department of Defense, Washington, developed a blast-mitigation standard to minimize hazards caused by glazing to personnel. Know as the Unified Facilities Criteria (UFC)-DoD Minimum Antiterrorism Standard for Buildings, the standard applies to windows, skylights, and glazed doors on new and existing inhabited buildings. In February 2012, the UFC 4-010-01 was revised with several significant changes. These include expanding the applicability of the minimum antiterrorism standards to the purchase of existing buildings, visitor centers, museums and visitor-control centers and expanding the requirements for design submittals, calculations, test reports, and narratives.

Additionally, the revised standard redefined conventional-construction standoff distance based on the type of construction materials and structural systems, which enables a project team to evaluate the resistance and strength of the structure with the standoff distances at a given site. Other modifications to the standard affect the requirements for unobstructed spaces and identifying required access control at building entrances.

Step Four: Whole-Building Solutions.

Anyone evaluating products for blast mitigation must think about the building as a whole. Windows, curtain walls, storefront framing, and entrances are all tested for blast

mitigation to ensure a safe building envelope. A comprehensive building solution is critical for optimum protection.

A great deal can be accomplished with today’s glass and systems technology. As products are evaluated for blast mitigation, it is important to consider what other safety, sustainability, and overall occupant comfort features they may also have.

When specifying products for schools, for example, daylighting and thermal performance are often considerations right along with safety.

Many studies over the years indicate that natural daylight stimulates the brain more than artificial light. The same studies suggest that student performance increases where more direct daylighting is used. Natural ventilation and emergency egress are two more factors that architects have to consider when designing schools and educational facilities.

The combination of aesthetics, functionality, code requirements, and simple logic plays a major role in an architect’s desire to use glazed entrances, storefronts, curtain walls, and operable windows. However, some are suggesting that schools or government facilities should be windowless or have fewer glazed openings to be safe.

Plans put into practice Government and federal facilities identify security as a top priority and often consider whole-building solutions. One such example is the Sarasota Police Headquarters in Sarasota, FL. When architects from Winter Park, FL-based Architect Design Group Inc. were developing the six-story, $38-million building they designed a facility that would achieve high energy performance and daylighting while delivering security against natural and manmade threats, balancing sustainability and security. The harsh Florida environment and hurricane-prone location was another major reason designers considered a comprehensive building solution.

The building contains more than 40,000 sq. ft. of exterior glass and 6,000 sq. ft. of interior glass. The exterior of the building features an impact-resistant curtain wall with insulating, laminated, low-e, impact-rated glass as well as impact-resistant entrances. A high-performance framing system used on the interior and several doors provides strength and durability. The design also allows ample daylight, which is important in public or government facilities where people often spend a great deal of time indoors.

The police headquarters achieved Leadership in Energy and Environmental Design (LEED) Silver certification from the U.S. Green Building Council (USGBC), Washington. By selecting products that achieved performance, safety, and aesthetic goals, the design team was able to provide occupants with a secure facility as well as energy and daylighting benefits, which contribute to overall occupant comfort.

The human element Buildings can affect their occupants by enhancing moods, affecting health and productivity, and protecting them from natural or manmade disasters. Each product in a building plays a role in the overall influence on its occupants.

Incorporating any element into a building requires careful consideration, but when it comes to blast mitigation designed to safeguard human lives, thorough assessments, attention to regulations, and whole-building consideration are key elements in specifications. Protecting what’s inside is critical and selecting products with the highest levels of performance and defense help accomplish this objective. After all, it’s what–and who–is inside that matters most.

Touch-Free Fixtures Tap Into Hygiene Touch-free innovations offer a number of benefits to a facility, including increased cleanliness and hygiene, operational savings, and a level of sophistication to its restrooms.

ealth-conscious end-users are behind the demand for hands-free products in commercial restrooms. Today’s society is germ obsessed, with industry reports estimating that approximately 30% of people avoid using a public restroom due to their fear of germs and other bacteria that reside on the surfaces of fixtures they would touch. However, the public is more likely to use restrooms with hands-free fixtures instead of manual types. The result is that specifiers and building owners are incorporating an increasing number of touch-free products in new-construction, renovation, and retrofit projects.

In today’s restroom stall, there are two primary touch-free elements that help reduce the spread of germs and bacteria: • Automatic toilet-seat-cover dispensers: Industry studies on toilet seats found that in restaurants, gas stations, and other public places, 97% of toilet seats harbor micrococacceae, which can cause skin reactions. Installing automatic toilet-seat-cover dispensers separate the user from such bacteria.

•

Sensor-operated flush valves: High-efficiency flush valves increase water savings for commercial properties and can significantly reduce contamination in a restroom. These flush valves also promote energy savings with the help of an infrared sensor beam that activates a flush cycle only when a user is in range, ensuring optimal performance, efficient operation, and cost savings.

Visitors are also accustomed to touchfree elements in the sink area of a commercial restroom. When these products are used in combination, visitors can remove as much as 99.9% of germs, according to Richard DiPaolo, an expert in the janitorial/sanitation industry.

• Automatic soap dispensers: Dispensers automatically distribute a pre-measured amount of soap for hygienic hand washing, eliminating bacterial colonies left behind on traditional products. They also feature easy-to-use bag refills that further reduce contamination.

• Sensor-operated faucets: Hands-free electronic faucets are a smart choice to help reduce the

spread of germs in any facility. It’s no surprise that professional groups give these fixtures good grades. A joint statement issued in April 2011 by the American Society of Healthcare Engineers, Chicago, and the Association for Professionals in Infection Control and Epidemiology, Washington, praised electronic faucets because they “lessen the risk of recontamination of hands after washing.”

Sanitary control isn’t the only benefit offered by electronic faucets. They also help conserve water and reduce the chance of flooding. The plumbing-management team at Vanderbilt Univ.

Hospital, Nashville, TN, reported that the use of hands-free electronic faucets for the past seven years has been a great success. They install electronic faucets in public areas, so there’s no worry about visitors turning something on and walking away with it still running. In other words, these fixtures are a win for everyone.

• Automatic paper-towel dispensers and electronic hand dryers: While hands-free faucets play an important role in keeping bacteria off hands

in a commercial restroom, automatic paper dispensers are also an integral component. The Centers for Disease Control, Atlanta, recommends the use of paper towels over hand blowdrying devices. Research shows that end-users are more likely to choose paper towels, leading to less cross-contamination. Damp hands are 1,000 times more likely than dry hands to contract and spread germs.

Reliable, touch-free restrooms There’s no denying the popularity, demand, and need for touch-free products. However, if the products don’t perform properly on demand, it is frustrating for the end-user. Consider the following factors to limit operation issues, ensuring these fixtures perform reliably from the user’s entrance to exit.

• High-quality products: When specifying automatic fixtures in a commercial restroom, be sure to select high-quality products. Specifiers should be careful about selecting electronic products from unknown or obscure manufacturers just because prices are lower. Reputable manufacturers provide sensor-operated fixtures that feature durable, solid brass, chrome-plated construction to withstand constant use. Vandal-resistant features are also a plus, preventing tampering or damage that can render them inoperable. Higher-quality products also include more advanced and reliable electronic components that help limit over-flushing and false sensing, two of the most common complaints associated with touch-free restrooms.

• Select the right settings: For a touch-free restroom to receive high marks, the facilitymanagement team must be familiar with traffic and usage patterns. Observe the flow of the restroom and see where and why lines are forming. In high-traffic locations or during peak usage times and seasons, it’s important to adjust the settings on sensor-operated products accordingly. For automatic paper-towel dispensers, greater paper lengths and shorter delays between paper feeds will keep visitors moving through more quickly, whereas shorter lengths and longer delays work well in facilities where time is not as crucial.

In the stall, dual-flush valves adjust automatically, using advanced electronics to ensure that every flush uses the right amount of water. Dual-flush valves rely on the timing of the individual in the stall to determine the strength of the flush in commercial water-closet applications, automatically reducing water usage by as much as 37% without sacrificing performance. The sensor-operated valves allow the user to be in range for as long as 60 seconds for a reduced 1.0-gallon flush. After 60 seconds, a full 1.6-gallon flush is activated, potentially saving thousands of gallons of water each year.

Public restrooms of all kinds conserve water with touch-free technology installed.

Keeping things flowing Products that feature a mechanical manualoverride button ensure that systems are always operational. If a product lacks such controls, the only way to solve functionality issues is to replace faulty components. If the warranty has lapsed or the manufacturer doesn’t cover replacement parts, keeping products operational can be costly.

Since touch-free products are automated, it’s important to perform regular service and maintenance checks to ensure that batteries are not dead and dispensers are not empty, leaving products unusable until the issue is resolved. If a facility does not have the resources to keep up with battery checks and replacement on a regular basis, selecting products with optional AC power adapters will keep restrooms running smoothly.

Touch-free restroom technology will evolve and advance as available products, features, and equipment continue to improve. Ultimately, touch-free innovations offer a number of benefits to a facility, including increased cleanliness and hygiene, operational savings, and a level of sophistication to its restrooms. With the right products in place and appropriate maintenance, touch-free fixtures and devices will reliably provide these benefits for years to come.

Renovate!

PEX Pipe Big Factor In Hotel Renovation Using PEX-a piping makes possible plumbing replacement in a historical building without tearing out walls.

Jayson Drake, Uponor North America

H

istorical buildings restored to their original look and feel can be awe-inspiring on the outside and exquisite within. But getting to that point while meeting all of the codes and regulations applicable to this special type of project can involve numerous challenges for building designers and installers. Nowhere are these complexities more acute than in the modern mechanical systems that must somehow fit within the confines of structures designed and built long ago to accommodate something far simpler and smaller.

“There are lots of hoops and hurdles the owner of a historical building must jump through during the renovation process,” said Todd Ringgold of Palmer Mechanical, a Tulsa, OKbased contractor that has made renovations of historical buildings a major part of its business in recent years. High ceilings—“at least as high as the original building, if not higher,” he says—and plaster walls are musts, of course. While the interiors hearken back to an earlier era, all of the amenities must be thoroughly modern and efficient to attract buyers and tenants. Updates typically include larger bath and kitchen facilities equipped with the latest conveniences.

Proper performance of those amenities demands an equally modern infrastructure, none of which can be conspicuous or take up much space to avoid detracting from the authenticity of the restoration. The updated wiring, ductwork, conduit, and piping for the communications, HVAC, electrical, and plumbing systems usually must fit into the available air space between the floors of these buildings, Ringgold said. “Essentially, we must squeeze a lot of piping into a very small chase.”

The Palmer Mechanical portfolio contains five historical-building renovations in Tulsa over the past decade, including the Philtower Building, the former Tulsa City Hall (converted into a hotel) and—perhaps the most notable of all—the landmark, $40 million Mayo Hotel project. All were design-build projects that allowed Palmer to do its own system-design work to match the infrastructure to the radically altered configurations of the buildings after they had been completely gutted.

“In these buildings, the newly enlarged bathrooms and kitchens don’t line up from one floor to the next as neatly as they did in the older structures with their simple tub-sink-toilet layouts,” said Ringgold, who has served as Palmer’s project

manager on each of the jobs. “That’s because the new bathrooms usually include large, marble-andtile showers with whirlpool tubs, marble-topped vanities, and bigger closets.”

While carving out additional space for larger, better-appointed bathrooms, Ringgold and his crews still must leave enough room for equally well-appointed kitchens, living areas, and bedrooms. “The piping, wiring, venting, and so forth have to be completely redone,” he explained.

PEX-ability The design-build process gave Palmer Mechanical another advantage: more decision-making authority over the types of building materials used on the projects. This enabled the company to use a different type of plumbing pipe: crosslinked polyethylene (PEX-a) instead of copper.

PEX-a’s flexibility and ease of use are major labor-saving, stress-reducing improvements over the rigid copper and plastic systems of the past.

Just as the inherent characteristics of copper led to its replacing old-fashioned galvanized steel and cast iron, the significant benefits of flexible PEX-a have made it an ideal solution for meeting

bought it for $250,000. Their vision was to restore its special character and former glory. The final result is now an elegant mix of hospitality and residential spaces, with 102 hotel rooms and 70 apartments ranging from 450 to 1,200 sq. ft. and offering views of the nearby Arkansas River, the BOK Center, and downtown Tulsa.

In its own way, the Mayo’s refurbished infrastructure is as impressive as its restored interiors and exterior. Galvanized-steel mains deliver cold water to each floor of the hotel, with the run-outs to the living spaces made of AquaPEX PEX-a pipe furnished by Uponor North America, St. Paul, MN. Each residential space has its own water heater, although hot water for hydronic space heating is delivered by one of the boilers located in a basement mechanical room. This setup entails two piping systems on each floor–domestic hot water and space heating–each made of PEX-a and running from each residential unit to one of two nearby mechanical rooms on each level.

“We installed about 70,000 feet of AquaPEX for the plumbing system and another 51,000 feet of Wirsbo hePEX for the hydronic heating and cooling runs,” reported Ringgold, who led a 20- to 25-man crew during an installation process that spanned five months. It is important to note that the Wirsbo hePEX (also manufactured by Uponor North America), features a special oxygen barrier to protect ferrous components in the system from corroding through contact with oxygen in the water.

A lot of pipe

the demands of historical renovation.

Manufactured with the Engel method, which results in a very high degree of molecular crosslinking, PEX-a offers exceptional durability and flexibility. That flexibility, combined with the availability of PEX-a in long coils, eliminates many of the fittings and connections required in rigid metal- and plastic-plumbing systems. Fewer fittings means less material, less installation labor, and fewer potential leak points, all resulting in more efficient installs at lower costs.

Ringgold happily put these advantages to work in all of the renovation jobs he has managed for Palmer Mechanical in recent years. His own first encounter with PEX-a came eight years ago at the behest of the new owner of a hotel in downtown Tulsa. Re-piping that building’s entire plumbing system with PEX-a, Ringgold estimated his labor costs were half what they would have been had he replaced copper with copper.

“Once we got on the project, we discovered we could re-pipe the building at a faster pace than the rest of the trades could renovate the rooms,” he recalled. “By the end of the project, I was a true believer.”

With their special demands and limited space, the subsequent renovation projects he managed for Palmer only strengthened his conviction. Ringgold had previously done plumbing-service work in many of these projects, so he was familiar with their peculiarities and understood how a full-fledged gut renovation with a sharp eye on history would only lead to bigger construction hurdles.

The Mayo The most impressive example is the Mayo, also located in downtown Tulsa. Built in 1925 by brothers Cass A. and John D. Mayo, the original 18-story tower housed 600 guest rooms—each with its own ceiling fan, a major selling point— and served as a gathering place for Tulsa high society and visiting dignitaries and celebrities.

(Oilman J. Paul Getty once made the Mayo his full-time home.) In 1980, the venerable hotel achieved recognition on the National Register of Historic Places, even as it struggled to regain its fading, grand-hotel luster.

Following the last of several botched attempts at restoration, the Mayo sat idle for nearly two decades until 2001, when the Snyder family

All of this piping—nearly 23 miles worth—had to be stacked or racked with the electrical, fire-sprinkler, venting, and communications lines in chases concealed inside the 9-foot-high ceilings above the hallways on each floor. The dimensions of these overhead chases, Ringgold estimates, were only “three or four feet wide and four or five inches in depth,” hardly big enough for a grown man to crawl through, let alone one charged with making leak-free pipe connections.

“That’s where PEX-a really comes into play for us,” said Ringgold. Installing long, straight runs of PEX-a pipe of as much as 140 feet within these cramped quarters was challenge enough. The saving grace: The PEX-a pipe required no connections since the pipe comes in coils up to 1,000 feet in length. Using straight lengths of copper would have required soldering a pipe joint every 20 feet.

“Shoehorning an installer into those little spaces with a torch would’ve been just asking for trouble. Why mess with fire in tight spaces, especially one with hard, plasterboard ceilings?” asks Ringgold, who figures that using copper would have boosted installation costs by as much as 30%.

PEX-a perks The special characteristics of PEX-a pipe also deliver other time- and money-saving advantages

Bend instead of break. Ringgold recalled one especially difficult part of the installation in which the layout called for routing plumbing lines through an attic area above the hotel ballroom. This space was “jammed with electrical gear,” so his crews needed to circle the lines around the equipment. With copper, every change in direction necessitates cutting the pipe and soldering two connections. With PEX-a, which has the smallest bend radius of any type of PEX, it’s simply a matter of bending the pipe in the desired direction. In this instance, the ease-of-use advantage had benefits beyond speed, given the precarious location of the attic above a set of stairs.

“Instead of trying to sweat copper connections while perched 25 to 30 feet in the air over a stairwell,” Ringgold said, “we were able to maneuver a continuous length of PEX-a pipe through the hangers in much less time and with less hazard and cost.”

Swift, sure connections. In places where pipe joints are unavoidable, making them is relatively easy when installers capitalize on the natural ability of PEX-a to expand and contract, using an ASTM F1960 cold-expansion connection.

One of the simplest, strongest, and most reliable connections available, it involves four simple steps: 1. Cut the pipe with a plastic-pipe cutter.

2. Place a PEX-a expansion ring on the end of the pipe.

3. Expand the pipe and the ring with a Milwaukee ProPEX M12 or M18 expansion tool.

4. Insert the larger-diameter fitting.

The pipe and ring will then immediately and naturally begin contracting back to their original shape, compressing tightly against the primary and secondary fitting barbs with as much as 7,800 pounds of radial force. There’s no deburring, torches, flux, solder, cements, or curing or cooling time.

The resulting permanent connection holds tight in tests of as much as 1,000 pounds of pull force. In addition, since the pipe is expanded before the fitting is inserted, it’s impossible to dry-fit the connection, eliminating the possibility of incomplete fittings and the resulting blow-off leaks.

As Ringgold noted, “The flexibility of PEX-a gave us not only much more maneuverability for the install, but also far fewer chances for problems post installation.”

Superior heat retention. The Mayo project was Palmer Mechanical’s first experience using PEX-a pipe for heating and cooling lines, and Ringgold was impressed by the fact that his crews did not need to insulate the pipe. Not only does PEX-a resist condensation on coldwater lines better than copper, but it also offers superior heat retention in hot-water supply runs.

In Brief: The Mayo Hotel Architect: Built in 1925, the original hotel was designed by George Winkler in the Chicago School vernacular developed by Louis Sullivan.

The base of two-story Doric columns supports 14 floors with false terracotta balconies, a two-story stone crown, and a dentiled cornice.

Glamorous surrounding and advanced features, such as running ice water and ceiling fans in each room made the Mayo a wellknown local hangout for celebrity entertainers such as Bob Hope, Mae West, and Oklahoma native son Will Rogers.

Before and After: The Mayo Hotel originally had 600 guest rooms; the redesigned, renovated building includes 102 hotel rooms and 70 luxury loft apartments.

Try, Try Again: Six renovation attempts failed before the current owners purchased the property and successfully completed a refurbishment that restored its original look while delivering modern amenities to residents and guests—all while maintaining its place on the National Register of Historic Places.

“We did not buy this building planning on doing any of this with it,” said owner Macy Snyder Amatucci, who is director of sales at the Mayo. “That wasn’t the plan. That was a dream, but a very farfetched dream. We never thought it would end where it is today. We’ve come a long way.”

such that no insulation was needed. “That saved a lot of installation time as well,” said Ringgold.

The voice of PEX-perience Todd Ringgold offers some tips for plumbing and mechanical contractors looking to tackle a large historical renovation: Familiarize yourself with the relevant rules and regulations. A smart contractor becomes thoroughly familiar with what local authorities will allow and then plans the project accordingly, down to minute details. On occasion, these rules may seem to border on pure fussiness, but that doesn’t mean a contractor will have much luck arguing his way free of them.

“At the Mayo, for example, they told us exactly

Get free product information at www.cbpmagazine.com

where we could position cleanouts—and the hallways were definitely off limits!” Ringgold recalled. “They also specified the paint color for the windows. Sounds like small stuff, I know, but that’s how seriously they take the issue of historical authenticity. There were no cleanouts in the hallways of the original structure, so there mustn’t be any in the renovated building either.”

Leave yourself some “wiggle room” in your budgeting for surprises. In fact, a contractor can pretty well count on more than one close encounter with the entirely unexpected.

That comes with the territory when doing historical renovations, warns Ringgold. “You don’t know what you’re up against until you start opening up the building. Then it may be too late.”

Ringgold believes that PEX-a is the way to go for plumbing and heating systems. Although he embraced PEX-a quickly after his initial experience in 2005, he knows that some contractors, engineers, and owners remain unconvinced.

Among those working with the tools, the biggest objection he has encountered has been an aesthetic complaint: It’s not as pretty as copper—an objection that Ringgold finds bewildering considering the economic arguments for PEX-a, including the comparatively high and rising cost of copper. That cost, in turn, makes copper a prime target for jobsite theft.

Still, some of the trades remain skeptical of plastic in general for reasons beyond appearance.

Many of these professionals hesitate because of their long, negative memories of polybutylene (PB) and the problems failed PB systems caused builders and installers around the country in the early 1990s. But the problems of gone-but-notforgotten PB have nothing to do with PEX-a, which was first commercialized in Europe in the 1970s and came to North America in 1984.

Ringgold pointed to the length of the warranty for PEX-a versus copper: In Uponor’s case, that protection extends 25 years on AquaPEX pipe and the ProPEX fittings installed by a factorytrained professional. “What copper producer offers that kind of warranty?” he asked. “For me, it provides so much peace of mind.”

The most important assurance of all for Ringgold is the trouble-free performance of the systems. “We have seen no problems and no complaints with the PEX-a systems on any of these historical-renovation projects, including the very first one that served as our learning curve. Their system still runs like a top.”

project LIGHTING New induction high-bays illuminate the concourses under the stadium’s end-zone seats.

Historic Lambeau Field, home of the Green Bay Packers, is getting an energy-efficient upgrade using induction-lamp technology.

Induction Lamps Light Lambeau O

ne of the National Football League’s most revered stadiums, Lambeau Field in Green Bay, WI, home of the Green Bay Packers, features the only true retro look in the entire league.

Recently the structure has been transformed from a football stadium that fans used only 10 days during the season to a Packers cultural center that can be enjoyed throughout the year.

Lambeau Field managers also implemented a major lighting overhaul. Powrtek Engineering Inc., an electrical-engineering firm based in Waukesha, WI, searched for a solution that would meet building codes and decrease maintenance costs. The final choice: 200-W induction high-bay fixtures from EverLast Lighting, Jackson, MI. Designed to improve safety and visibility and meet emergency regulations, the induction high-bays offer 100,000 hours of lamp life and an efficacy of 85 lumens/W, making the technology very energy efficient and cost effective. The concourses under the south end zone received 71 induction high bays to supplement existing lighting.

Several hundred additional induction fixtures will

be installed throughout the stadium this winter.

“The manufacturer provided a color temperature that we needed as a custom blend at 3,000 K,” said Greg Sadowski, president of Powrtek Engineering. “Additionally, there were strict emergency-lighting specifications that we had to meet. The fixture had to be able to turn on within 10 seconds in the event of an outage.

The induction fixtures are doing double duty: They possess the required color rendition in

Induction technology is an electrode-less lamp that has been around for more than 100 years.

Due to recent advancements, it has become an effective lighting option for roadways, parking structures, municipalities, warehouses, and largescale facilities. With no electrodes, the lamp relies on the fundamental principles of gas discharge and electromagnetic induction to produce light.

Based on these principles, light is generated using gas discharged through magnetism. Rings with magnetic coils create an electromagnetic field

addition to the instant-on feature.

“HID [high-intensity-discharge lamps] cannot provide the specifications required,” Sandowski added. “Furthermore, with induction’s 100,000-hour lifetime on their fixtures, it was an easy decision. We would’ve been lucky to get 20,000 hours out of any other fixtures. Once we took the warranty and the lower maintenance costs into consideration, we knew that we wanted to go with induction.”

project LIGHTING using a high frequency generated by an electronic ballast. This field goes around a gas-filled glass tube. The discharge path induced by the coils forms a closed loop, accelerating free electrons that collide with mercury atoms and excite the electrons. As the electrons begin to reach a lower, more stable level, they give off energy in the form of invisible ultraviolet light, which converts to visible light when it passes through a phosphor coating on the surface of the tube. The lamp’s unique shape maximizes the fields generated during this process.

The system blends technology that was first discovered more than 30 years ago with new features that were not commercially practical until now. Induction has overcome the barriers of high cost and technological setbacks such as electromagnetic interference, lumen depreciation, and inability to dim. ”The induction high-bay fixture has been sought out especially in large facilities where lower maintenance costs have been deciding factors as a result of the long life span of the fixture and the 10-year warranty,” said Jim Fink, who covers the state of Wisconsin for Alternative Sales and Marketing, Forest Lake, MN, and worked with Powrtek on the project. “Once we began evaluating the new construction, it was obvious that was the direction that we would go.”

“The success of the induction fixtures in the upper Midwest region has been phenomenal for reasons such as engineering support, providing lighting layouts, custom modifications when needed, product stock, and a U.S.manufactured product,” said Fink. “The key successes in this market are the operation of the induction lighting in exceptionally cold weather.”

EverLast Lighting engineered its 200-W Huron aluminum high-bay unit to match the existing lighting temperature and protect the visual integrity of the historic stadium. Virtually maintenance-free for as long as 15 years, the fixtures are 50% to 70% more energy-efficient than metal halides. The fixtures provide a more natural, higher color-rendition light than traditional metal-halide fixtures.

In addition, induction lighting fixtures are available with a bi-level dimming option triggered by photosensors, providing even more energy savings when areas are vacant. Building codes often require large sports stadiums to have lights on all day or all night, regardless of the lighting need. Bi-level fixture controls present an opportunity to save energy by dimming light levels in unoccupied areas. They also can turn off perimeter lights in areas that receive sufficient daylight to meet lighting needs.

Artificial sunshine In addition to the savings from bi-level controls, replacing existing light fixtures with high-performance fixtures, such as induction, can produce significant energy and lifecycle cost savings. Fixture replacements and bi-level controls can create peak demand reductions (kW) and hourly energy-use reductions (kWh). Typical energy savings for parking lots and garages retrofitted with bi-level lighting are 20% to 70%, depending on the previous and newly installed equipment.

“Proprietary to the manufacturer, our bilevel option includes an advanced internal heatmanagement system designed for separation and airflow between the ballast and lamp. By isolating specific areas, the technology is able to ensure electronic components have a longer life cycle,” explained Justin Baldwin, EverLast vice president.

“When developing the technology, we took into consideration fixture maintenance and ease of installation.” The result is a lamp with a life span roughly equivalent to 100 incandescent, five HID, five typical fluorescent, or two LED lamp changes.

Because lighting technologies vary, the lighting specifiers considered visibility lumens for the Lambeau Field application. Metered footcandle readings—the intensity of illumination without regard for the contribution of the eye’s rods in color recognition and how the human eye works—only tell half the story. The more artificial light varies from natural sunlight, the less effective it is for visual acuity.

Induction is the closest light to the natural, full-color spectrum of sunlight. Visually effective lumens (VEL) are the measure of lumens factored to account for visual acuity. VEL reflects a combination of the color-rendering index (CRI) of a light source as well as the Kelvin temperature (K). Induction lighting combines very high CRI with 5,000 K, and the natural, full-color spectrum of sunlight. The result is excellent acuity.

However, management at Lambeau Field wanted to maintain the feel of their stadium, which is why they decided to pursue the custom 3,000 K blend, which emits a warm light that matches the history and character of the stadium. “Projects like Lambeau Field get us excited because we are lighting-solution providers, not just fixture manufacturers,” explained Brandon Marken, vice president of sales at EverLast. “When customers and/or our representatives come to us with a specific set of criteria and needs, we feel confident that we can deliver a customized solution that will exceed their expectations.”

Induction vs. LED Although LED technology has become a major force in the lighting industry, several factors drove Lambeau managers’ decision not to pursue LEDs as a stadium lighting solution: 32

According to county budget director Sherry Seright, there were growing signs that the building’s more than 30-year-old cooling and heating system needed to be replaced.

“We found water in the basement from the old boilers, and the pipes were starting to leak. The indoor units were loud, moldy, and fuzzy, and everyone disliked the huge, ugly condenser unit sitting prominently on the roof of our handsome … building, spoiling the view,” she said.

The County Board of Supervisors wanted to learn more about going green and knew it was time to replace the courthouse’s failing, outdated HVAC system. A proposal from Vic Amoroso, a 40-year HVAC design engineer and president of A&J Associates PC, North Liberty, IA, caught their attention.

Amoroso explained the basics of a closed-loop geothermal system and how smoothly it would work in tandem with a variable-refrigerant-flow (VRF) zoning system from Mitsubishi Electric Cooling & Heating, Suwanee, GA. Bruce Senti, an independent sales representative from Mitsubishi Electric, explained to Amoroso how the VRF zoning water-source system would interface with a geothermal field.

“Our new W-series modular units perfectly combine the energy effectiveness of geothermal systems with the excellent efficiencies of our VRF zoning technology,” said Senti. “These new units are 30% smaller than previous models and can be easily transported down the stairs into the basement of the courthouse. By connecting to the geothermal loop, backup heat would not be needed as it might with air-source units.” The system, which uses water instead of air as a heat-exchange medium, is superior to air-cooled systems, especially in Iowa, where it is not uncommon for winter temperatures to dip below –10 F. The system’s dry mode is effective for the months of July and August, which can make Iowa feel like a greenhouse.

Because of the hot, humid Iowa summers, Senti recommended another key VRF zoning product, a Mitsubishi Electric City Multi dedicated outdoor air system (DOAS). The DOAS would supply outdoor ventilation air to the courthouse, delivering the proper amount of fresh air to each room, and also provide ample dehumidification without excessive reheat. The DOAS would also increase the VRF zoning system’s energy efficiency because it pre-conditions outside air for introduction into the downstream HVAC units, reducing the load on the HVAC system.

The fact that the DOAS and the VRF zoning system were designed to work together was appealing to Senti. “The DOAS from Mitsubishi Electric was very convenient for us,” he said.

project HVAC “Because the outdoor-air system and the VRF system were manufactured by the same company, we didn’t have to cobble together a system with components from different manufacturers that might decrease the system’s energy efficiency.

Additionally, this system combination provided us with a one-stop shop regarding parts, warranties, installation, service, and repair.”

Amoroso was interested in the VRF zoning system because its engineering design would overcome the installation challenges posed by the 105-year-old building with its 24-inch-thick limestone walls. The gas-fired boiler supplying heat to the courthouse would be eliminated, providing the county with significant natural-gas savings in the winter. But Amoroso also saw something even more significant—the VRF zoning system efficiencies, coupled with the heat-sync exchange of the campus geothermal field, could serve the courthouse and the new jail addition across the street. The geothermal campus was a hybrid, closed-loop system with 60 vertical and 40 horizontal wells. Amoroso’s presentation to the board convinced the members that this was the right decision.

tion. Mechanical contractor Heath Allard, president of Climate River Valley, Eldridge, IA, said, “This smooth installation had a lot to do with the native intelligence of the Mitsubishi Electric VRF zoning system design. Because it’s the industry’s only two-pipe system, there are far fewer fittings on the refrigerant lines, which saved us a lot of labor and equipment costs. Because the

W2-series units are installed indoors, we did not have to drill through the thick limestone walls, which would have made quite a racket.”

“There are so many benefits to this new system it is hard to know where to begin,” Amoroso said. “First of all, there is the historic preservation accommodation of this technology, which is the least intrusive, less destructive factor

of this two-pipe system. There is the super-quiet aspect of all the indoor units, ideal for an office environment: It’s so quiet, people often ask if it is operating. There is the system’s remarkable ‘dry mode’ setting, which has great impact on indoor comfort during our humid summers. Then, there is the unique 100% inverter-driven compressor that varies its speed to match the indoor cooling or heating demand. This is great engineering.

When the system is operating at partial load, the energy efficiency is significantly higher than that of a standard fixed-speed system.”

Inside the buildings, the VRF zoning-system heat pumps recover excess heat and reuse it to heat cold spots and to warm water. When the building temperatures are satisfied, the excess heat is then shared with the second building served by the campus geothermal loop. The second building’s heat-pump system uses the shared energy to maintain the temperatures in the jail addition. If both building temperatures are satisfied, then the excess heat is transferred to the loop field to be stored for later use. This use of a single energy unit provides overall campus energy savings.

“We sized the geothermal loop field to handle 450 gallons/minute flow at the design heating and cooling load,” Amoroso continued.

adjust to what is needed in the overall campus balance. We have observed this past summer that the field can handle the campus system heattransfer requirement with just 20% of the design flow. The savings in pumping energy alone has been tremendous. This result is due in large part to the ability of the courthouse VRF zoning system to share and save heating and cooling energy for use in the other building and for storing for later use.”

Positive verdict “We are all thrilled with the performance of this technology partnership,” Seright said. “As budget director, I can tell you the clearest proof of the success of our decision came when the 30,000-sq.-ft. new jail addition came online and was tied into the campus geothermal field between both buildings. The energy bill did not move up one tick! That’s amazing proof of how this technology works.”

“Perhaps best of all, we were able to remove that hideous chiller on the courthouse’s roof that spoiled its classic lines,” she continued.

“The diminutive demands of this VRF zoning system have helped us bring back the grandeur of our courthouse.”

project INTERIORS One of the most popular exhibits at the Nature Research Center is the Daily Planet, a threestory globe of the earth.

the existing museum with a two-level pedestrian bridge. The upper story features a progression of handmade tiles, created by artist Barbara Page, positioned along handrails to represent the passage of geologic time. In a nutshell, one can start at one end of the bridge and see tiles portraying life forms dating back 542 million years.

By the time he or she gets to the other end of the bridge, the tiles impart images of living creatures that have evolved from back then until right now.

he North Carolina Museum of Natural Sciences’ new Nature Research Center wing, a state-of-the-art 80,000-sq.-ft. building with its cornerstone three-story globe of the earth, The Daily Planet, opened in late April 2012 in Raleigh. Its declared mission was to bring research scientists into the public eye, demystify what can be an intimidating field of study, and ultimately inspire educators and students toward a new generation of young scientists. According to the museum’s communications director, Jon Pishney, “Traditionally, museums show us more about what we know. Our new Nature Research Center gets visitors so involved they leave after learning via hands-on processes.”

Designed to meet LEED Gold criteria, the new wing offers highly visible research laboratories where qualified scientists conduct research projects while visitors are right next to them, observing and learning. Additional investigative labs offer visitors a chance to perform their own small-scale experiments and try their hand at using tools of the trade.

“This way, we’re able to get visitors more directly involved in the scientific process,” added Pishney. “It’s very possible at the Nature Research Center for a museum guest to use a high-powered microscope to look at plant or animal cells hundreds of times bigger than life.”

The Nature Research Center is connected to

“These exterior hand-made tiles were installed in a stainless-steel pan,” said Jason W. Banks, LEED AP, project manager, BD+C at David Allen Co., an NTCA 5-star contractor and CTEF certified installer with headquarters in Raleigh, NC. “We knew from the start that working with the museum would involve a number of very unique tile projects.

That’s why we trusted the Laticrete System for all installation materials. We used Latapoxy 300 adhesive for the handmade ‘time tiles’ due to its bonding strength. We caulked the entire perimeter and joints of these with Laticrete Latasil highperformance silicone sealant. Glass tile at the café was installed with Laticrete 254 Platinum. Before bathrooms were tiled, we protected all substrates by waterproofing them with Laticrete Hydro Ban. Each time, the outcome was perfect.” All products are from Laticrete International, Bethany, CT. The team from David Allen worked throughout specific areas within the new wing, primarily using Dallas-based Daltile products in the main bathrooms, kitchen, and café. Horizontal granite was specified for the main lobby entrance and as stair treads on the monumental floating staircase. “Great coordination work was done by the general contractor, Clancy & Theys Construction Co. of Raleigh, to get the main lobby and kitchen areas completed on time. The glass barrier around the edge of the floating stairs, for example, could not be put in place until the granite treads and landings were installed,” said Banks.

“When it comes to the selection of products, our hands are tied here a bit, as the architect dictates what tile materials they intend and specify as a basis of design,” Banks said.

“The architectural firm that designed the Nature Research Center, O’Brien/Atkins Associates PA [Durham, NC], did an outstanding job choosing products that were both beautiful and functional, while at the same time qualified for LEED points.

“With my knowledge as a LEED AP BD&C, I understand the LEED scorecard and thus can properly fill out the paperwork for the GC. This helps streamline the process a bit for them. It also helps when looking to collect LEED points within the materials selected. While the specification may indicate only a regional requirement for the product, I can research the product and perhaps add to the recycling content LEED point.”

▲ A series of handmade tiles represent the passage of geologic time. Visitors can follow tiles portraying life forms dating back 542 million years.

Granite serves as the treads on the monumental floating staircase. Despite the visual weight of the stone, the glass barriers around them create the illusion that the slabs are floating.

Rock stars One area where Banks had some leeway was the choice of setting materials used. He explained that the LaticreteSystem was a great choice for this project due to optimal performance and the convenience of the company’s Hamlet, NC, location. “That allowed most of the installation products used to contribute to the regional-materials LEED certification.”

Greene County granite and Virginia Mist granite were fabricated by North Carolina Granite Corp. in Mt. Airy, NC. Again, because the materials were shipped from their source location less than 500 miles from Raleigh, points were added to the project’s LEED scorecard.

For the museum’s 24-hour grand opening, more than 1,000 people stood in line, waiting 45 minutes for a chance to go inside the threestory globe that had gradually taken shape over the past year. Many were interested in the center’s philosophy of getting visitors interactively involved with scientists. “We’re taking scientists out of their lab coats and isolated labs and putting them into the spotlight,” said Meg Lowman, director of the center. “They are the new rock stars.”

The North Carolina Museum of Natural Sciences’ Nature Research Center has moved its tile-and-stone installation into a veritable spotlight position, as well. “Believe it or not,” Banks concluded, “there is a great deal of scientific know-how involved in these various tile projects. Maybe someday, a technical-services guru from Laticrete will be on hand in this building, offering cutting-edge information to a young, interested generation of potential tile-installation professionals about the correct ways to install tile and stone.”
