The wait is over. The premiere resource for HVAC products is ready! The new Titus Product Catalog is now available.

Titus takes a moment to reflect on the life of Bob Langmade and his impact on the HVAC industry.

The future is very bright in engineering with Trenton Yarbrough leading the way with fresh ideas and innovative concepts.

A New Direction for Titus My new role at Titus as VP of Sales and Marketing is the natural next step in a career of applied HVAC sales, engineering and marketing. I joined Titus after McQuay International where I served as the Vice President of National Accounts and Consulting Sales. While at McQuay I was responsible for strengthening key relationships with manufacturers’ representatives and large consulting engineering firms and their National Account customers. This experience with top tier manufacturers’ reps helped me learn the benefit of applied HVAC experts working with contractor, engineers and owner to find the best solutions for their buildings. We have the best reps in North America! My experience at Carrier Corporation and Johnson Controls helped me understand commercial building controls and mechanical systems. There is nothing like two weeks of pneumatic controls training in Milwaukee, WI in the winter of 1989 to teach a novice engineer about how VAV boxes and valves work. I hold a Bachelors of Science Degree from University of Illinois and an MBA from The University of Dallas Graduate School of Management, but my real education comes from learning from customers in their environments. Customers will always tell you what they want when you ask. It’s my job at Titus to be sure we listen well and respond with the absolute best service and solution.

Keith Glasch - Vice President of Sales and Marketing our dedicated application engineers for each of our main businesses: ◊ Grilles, Registers and Diffusers (GRD); including Critical Environments ◊ Terminal Unit applications including UnderFloor Air Distribution (UFAD) and Fan Coils ◊ Chilled Beam and Displacement Ventilation applications Our new facilities in Plano have increased the capability to apply our products in real situations and help engineers and their clients see firsthand how Titus can serve their needs. I am excited about the future at Titus!

While earning my LEED AP I gained a better understanding of Green Buildings and ASHRAE Standards 62.1, 55 and 90.1 as they relate to LEED certification. The importance of energy efficiency and human comfort in a total building HVAC solution works in conjunction with Titus’ offerings. We have so many directly applicable solutions to maximize LEED points, and are working directly on more every day. Combining my HVAC equipment and controls experience with the decades of Titus employees’ experience allows me to help Titus reach the highest level of Leadership in Air Distribution. Our new direction includes increasing

Woodgrain Finishes now Available Finally, the elegance of wood meets the durability of aluminum, as Titus introduces its new line of woodgrain finishes.

Aluminum has been a tried and true element of air distribution, because of its flexibility, sturdiness, and the fact that it is very light weight.

DECORATION Then, a preprinted film transfer with organic photosensitive pigments and cellulose resin is completely wrapped around the product. The profile is positioned on the surface of a movable trolley, and air is removed through a vacuum suction system. The result is a perfect thermoprint. The trolley is then placed in a special oven, where the decoration is effected, turning the ink pigments from solid into gas and back to solid inside the paint layer. After cooling, the film is removed. Combined with other breakthrough technologies we apply to the endeavor, this process accounts for why our system is a global leader in color coating quality.

These two ingredients can now be combined to create a truly singular aesthetic in our industry. The process is called sublimation.

Additionally, the process can produce either a textured or smooth finish for most woodgrain choices, which results in more than 40 new finish options for Titus.

PREPARATION AND COATING First, the raw aluminum surface receives a traditional pretreatment of a chemical conversion, creating a thin layer of amorphous oxide with coating. Electrostatic guns then apply a 2.5 mils layer of nonhazardous powder paint. The polymerization is done with a 400째F temperature for 20 minutes. The base coat ensures adequate hardness of the final product, and protects the aluminum from light, weather, abrasion, corrosion and humidity.

Initially, the woodgrain finishes will be offered on the CT product line only, because the process is conducive to coating a fully assembled product. However, once the logistics are refined, the plan is to expand the offering to other architectural products.

Wood has long been the symbol of sophistication and cultivated beauty in furniture, fixtures, and architectural accoutrements. It can bring a unique warmth and beauty to any space.

Our New Titus Catalog is Open for Business

t has been over three years since Titus last produced a product catalog. In that time, we have seen significant growth and change both internally and within the HVAC industry. Titus, now has new leadership and the world is more energy conscious and focused on Green Building design than ever before. We have also seen how the economy has impacted our industry as well. New product lines have been added that center around conserving energy and we’ve changed our focus to produce clever, creative, comfort solutions that are innovative and superior to the competition. With all this to work with, we put our best minds together and created the new Titus Product Catalog. The new catalog is now broken up into four different sections – Grilles and Diffusers, Terminal Units, Energy Solutions, and H2O (water side). Previously, we had announced that there would be five books, but we decided to include the Critical Environment diffusers with the Grilles and Diffusers book. Splitting our existing 1100 page book into four separate

On Air | WINTER 2012 EDITION

books wasn’t as easy as it seems. We also added Chilled Beam products and Displacement Ventilation systems to our existing product offering since the last time we printed a catalog. This process presented unique challenges that we overcame and now everyone benefits from that hard work. The individual catalogs are lighter and easier to take with you to visit clients. Another benefit is that as new products become available or data changes, it will be easier and quicker for us to update one or two books instead of waiting to update an entire catalog again. Also, by separating our products into different books, it makes it easier to sell or find a specific product. Most importantly, it is up-to-date with the latest and most accurate information related to our products which includes performance data, specifications and product descriptions. The design of this catalog was different as well. First, we switched from using product photos to using renderings for as many products as we could. The renderings are crisp and www.titus-hvac.com | www.titus-energysolutions.com

clean and allow us to emphasize special components of a particular product or display it in a certain perspective for viewing. Then we included several installation or product related photos in all of the books. A common request that we receive from time to time is for installation photos of various products. We viewed this as an opportunity to fill a need for information with this version of the catalog. The installation images vary from section to section and are spread out throughout the entire series of books. It is our hope that this small number of images assists you when you need access to a quick image for reference.

Section 1 - Grilles & Diffusers

The Grilles and Diffusers section contains all of Titus’ grilles, diffusers and other products that fall under this heading. Critical Environment diffusers, Chilled Beam products, Displacement Ventilation systems, and VAV diffusers are also featured here.

Section 2 - Terminal Units

The Terminal Units section contains all of Titus’ terminal units. This extensive collection of terminal units includes Fan Powered, Retrofit and Miscellaneous terminal units as well Accessories for the units. As an added bonus, we’ve also included our UnderFloor section.

Presently, the catalog is being printed and will be shipped to you soon. It’s quite possible that you will receive your shipment before this edition of On Air is available at ASHRAE. It is our sincere hope that this new catalog edition meets your HVAC needs and gives you the necessary tools to grow your businesses.

Section 3 - Energy Solutions

The Energy Solutions section is a new book for Titus. It contains our best energy saving products which include the EOS, the Plexicon, the DynaFuser, our UnderFloor product line and a whole host of Displacement Ventilation and Chilled Beam products.

Section 4 - H2O

The H2O section contains Fan Coils, Air Handlers and Chilled Beam products.

On Air | WINTER 2012 EDITION

The Patrick Heath Public Library in Boerne, Texas is a LEED Silver Certified building designed to meet ASHRAE Standards.

Designing for Comfort per ASHRAE Standards 55 and 62.1 The goal of a room air distribution system is to provide thermal comfort and a healthy living environment for occupants in the space. ASHRAE Standard 55-2010 Thermal Environmental Conditions for Human Occupancy and ASHRAE Standard 62.1-2010 Ventilation for Acceptable Indoor Air Quality provide designers with the guidance to optimize health and comfort in building spaces. Many codes including LEED 2009 require compliance with these ASHRAE Standards. This article will outline the goals of these standards and illustrate how to comply with these requirements. The occupied zone as defined by Standard 55-2010 reads: â&#x20AC;&#x153;the region normally occupied by people within a space, generally considered to be between the floor and 6 ft. level above the floor and more than 3.3 ft. from outside walls/ windows or fixed heating, ventilation, or air-conditioning equipment and 1 ft. from internal walls.â&#x20AC;? The space from the interior walls inward 1 ft. serves as a mixing zone where room air is entrained into the supply air jet and mixes to provide thermal comfort in the occupied space. When designing UnderFloor Air Distribution (UFAD) systems or Thermal

On Air | WINTER 2012 EDITION

Titus DVRI displacement ventilation diffuser shown in the Willard Elementary School in Concord, Massachusetts. Displacement Ventilation (TDV) systems, the occupied area around the outlets may be excluded to a boundary where the total air jet from the outlet contains velocities greater than www.titus-hvac.com | www.titus-energysolutions.com

50 feet per minute (fpm). These areas may also be known as the “clear zone”, “adjacent zone”, or “near zone”. Any design must also include an adequate supply of Ventilation Air to the breathing zone of the space. ASHRAE 62.1-2010 defines ventilation air as “that portion of supply air that is outdoor air plus any re-circulated air that has been treated for the purpose of maintaining acceptable indoor air quality”. The breathing zone is “the region within the occupied space between planes 3 and 72 inches above the floor…”. We will discuss additional requirements for ventilation air later in this article. The primary factors to be considered when determining conditions for thermal comfort in the occupied space are: 1) Temperature, 2) Air Velocity, 3) Humidity, 4) Clothing insulation, and 5) Activity level of the occupants. All of these factors are inter-connected when determining the general occupant comfort of a space. The ideal temperature in a space (operative temperature) is where the occupant will feel neutral to their surrounding neither feeling any heat loss to the space or heat gain from the space. While the range of acceptable operative temperature may vary depending on other conditions, ASHRAE 55 requires the “Allowable Vertical Air Temperature Difference-Between Head (67”) and Ankles (4”) is limited to 5.4 F (3.0 C)”. Ideal air velocity in the space can vary with other factors but in general the goal is to keep spatial velocities less than 50 fpm during the cooling mode and less than 30 fpm during the heating mode. For many years, Titus has recommended maintaining the relative humidity level in the space between 25-60%. ASHRAE 55 does not define a lower limit and requires the dew point temperature be less than 62.2 degrees (F). Another factor affecting comfort is the clothing insulation level of the occupant. In most office environments, occupants clo level is between 0.5 and 1.1, where 0.5 would be a person wearing no socks, sandals, short sleeve shirt or blouse, and shorts or skirt. The 1.1 clo level would include long pants, socks, long sleeve shirt and dress coat or sweater. The range of operative temperature where both a 0.5 and 1.1 occupants are in the same space is very narrow. The final item of consideration for design comfort is the intended activity level of the occupant in the space. In most office environments the metabolic (met. Rate) is between 1.0 and 1.3. This includes occupants who are sedentary to casual movement about the space. The three common methods of room air distribution used in commercial buildings in the United States are fully mixed, (e.g. overhead distribution); fully stratified (e.g. displacement ventilation); and partially mixed, (e.g. most underfloor air distribution systems). Since interior zones usually have adequate heat loads from occupants and equipment and few heat losses, the discussion for interior spaces will be cooling only. For the perimeter spaces, discussion will be how to meet the requirements for heating and cooling from the same overhead outlet. Design methods for cooling an interior zone and heating a perimeter zone vary with each method. www.titus-hvac.com | www.titus-energysolutions.com

For fully mixed systems, the pattern of the air delivered to the space must be considered when selecting an air outlet. Ceiling diffusers typically exhibit flow in a circular (radial) or cross flow (directional) discharge air pattern. The circular pattern usually provides shorter throw, higher mixing and tends to maintain ceiling effect to low velocity before turning back on itself. This pattern is ideal for variable air volume (VAV) cooling by providing less drop and more uniform temperatures in the space. The cross flow (directional) air pattern has longer throw but with less induction may lose ceiling effect creating drafts in the occupied zone. Plenum slot diffusers typically discharge air in a directional air pattern but some are available with “spreaders” to produce a more radial discharge air pattern. Sidewall grilles equipped with vertical deflectors can be adjusted from zero degree (directional pattern) to 45 degree spread (radial pattern). So, regardless of the desired type of outlet, the air pattern can be either radial or directional to best meet the comfort requirements of the space. Proper selection for comfort can be insured by using the ADPI selection program in TEAMS.

The Titus DynaFuser installed in the Virginia Tech Solarhouse. Typically for perimeter applications where the same outlet is being used for both heating and cooling, a linear slot diffuser or plenum slot diffuser is employed. When a fixed air pattern diffuser is used, it is typical to supply half of the air across the ceiling for cooling and half down the glass for heating. For perimeter heating, the requirements for table 6-2 of ASHRAE Standard 62.1-2010 must be considered. The intent of table 6-2 is to insure that the ventilation air supplied to the space be delivered to the breathing zone as well. For ceiling supply of warm air with a ceiling return, the requirements for heated air are to reach a terminal air velocity of 150 feet per minute (fpm) to within 4.5 ft. of the floor. To a terminal velocity of 150 fpm or more, air is temperature independent which means the distance air will travel will be the same for isothermal air (catalog values), warm air and cool air. This means that during heating, ventilation air will be pushed down into the breathing zone with enough heat energy to meet Standard 55’s requirement for a temperature gradient of less than 5.4 degrees. In addition, the differential temperature between warm supply air and space temperature with a ceiling return On Air | WINTER 2012 EDITION

must be 15 degrees or less. Thus the maximum supply air temperature for a 75 degree room would be 90 degrees. When the heating supply air temperature exceeds the 15 degree limit, the ventilation air volume for heating must be increased by 25%. Choosing an auto-changeover diffuser like Dynafuser or EOS does not change the Standard 62.1 requirements, but will lower energy cost and improve comfort in the space. Delivering all the warm air down the glass during heating will save energy. With a fixed pattern diffuser, half of the warm air will be discharged across the ceiling and with a ceiling return can be short circuited without reaching the occupied space level. Additionally, higher comfort will be realized in the space as the heated air can be designed to deliver warm air all the way to the floor. Comfort may be increased during cooling as well as the cool air will be projected across the ceiling eliminating the potential for drafts from the jet projected down the glass with a fixed pattern diffuser. For partially mixed air distribution systems (typically UFAD), the core area usually experiences even loading throughout the occupied area. The goal of partially mixed systems is to save energy by comfort conditioning the lower occupied

level in the space and allowing the upper level of the space to stratify. Occupant comfort is achieved by delivering cool conditioned air from the plenum under the floor through swirl diffusers or rectangular shaped outlets near the occupants work area. Individuals can enhance their personal comfort by adjusting the damper at the outlet near their workspace. For common areas such as hallways and break rooms, outlets can be equipped with actuators that are controlled by a common thermostat located in the space. Perimeter zones for partially mixed systems create a greater challenge as the loads are dynamically changing due to outdoor solar and air temperature changes. A common method for perimeter zone control is locating a low profile fan powered terminal unit under the floor near the perimeter supplying air to linear bar grilles. The fan powered terminal can be equipped with an electric or hydronic coil. Cool plenum air can be supplied to the outlets when cooling is required and the coil can be employed to warm the air as required during heating conditions. The design challenge is selecting outlets that will limit the throw of the air pattern so that air will not bounce off the ceiling and create drafts in the adjacent occupied area. www.titus-hvac.com | www.titus-energysolutions.com

Energy to operate the fan terminals can be eliminated and higher comfort can be achieved on the perimeter by using the TAF-L perimeter distribution outlets. With a 6” wide custom design TAF-L bar grille located along the perimeter of the space, the modular 4’ long TAF-L-V (cooling), can be attached to provide up to 225 cfm (at 0.07” plenum pressure) per 4’ unit of cooling. The TAF-L-V damper is controlled by a space thermostat to provide cooling as required. The special arrangement of bars in the grille is designed to limit the throw from the outlet during cooling. The 4’ long TAF-L-W or TAF-L-E heating module can be attached to the TAF-L grille to supply up to 3000 Btu heat to the perimeter. The heating units operate by combining the cool convection currents from the glass with the warm currents on the floor. The mixture is induced through the heat exchanger with warm air being discharged through the grille and up the glass. Space temperature is controlled by a room thermostat controlling the water flow or electric current flow to the electric heating element. The modular design allows the system to be custom designed for use in multiple climate regions. Fully stratified design (typically TDV), conditions a space by discharging cool supply air through an outlet located at floor level near or in a wall or may be centrally located in the open space. Low velocity air (< 80 fpm) is discharged horizontally across the floor. Air moves with little mixing across the floor

until it contacts a heat source such as an occupant or piece of warm equipment in the space. Cool air will mix with the radiant heat from the source and stratify toward the ceiling. The return is usually located at or near the ceiling. The area between the outlet and where the air speed reaches 40 fpm is the “clear zone” and should not be included in the occupied area. Titus provides units with adjustable air patterns so the clear zone can be controlled to meet project requirements for space occupancy. ASHRAE Standard 62.1 table 6-2 provides a 20% bonus for TDV systems. This means that ventilation air can be reduced by 20% or the 20% can be used toward the 30% required for an additional LEED IEQ credit 2. While TDV systems typically require a separate system for heating, Titus has introduced the Plexicon heating/cooling diffuser. A standard rectangular outlet is located near or mounted in a wall discharging cool air from the upper chamber. When heating is required, an internal baffle is moved to change the flow of air from the upper chamber to the lower chamber where it flows through a linear bar grille to satisfy heating requirements. Regardless of which type of system you are using on your project, studies have shown that occupants who are comfortable are more productive. Designing for comfort, keeps paying back dividends forever.

Titus Open House a 100% Certified, Grade A Success

ovember marked the one-year anniversary of the move to our new, state-of-the-art facility in Plano, Texas. To celebrate, we invited our customers to Texas for some 100% grade A certified Angus beef, a lab tour, and some valuable strategic planning.

facility. We spent most of the morning touring the building and lab, while explaining the thought process that went into each area of the office and lab. It gave us a unique opportunity to talk about where we are going and then showing how we will get there.

The first day included an intensive, all-day session with our newly formed Rep Council. Although it had been several years since the last Rep Council disbanded, we felt it was the perfect time to resurrect the group to allow us to gather input on our direction as a company from several of our key representatives.

The positive feedback we received was overwhelming and it really proved two very important things to us. First, we really do have the best customers in the industry and, secondly, these events are critical to our continued success and the success of our valued partners.

The new Titus Rep Council put together an impressive list of action items, which should contribute greatly to our mutual success in the short and long term. Our commitment to the Council is to provide periodic progress reports on the initiatives with the goal that we will have several of them completed by our next meeting in Chicago in April, 2012.

On Air | WINTER 2012 EDITION

James Gray, GRD & Displacement Ventilation Product Manager, briefly talks about the Solar Plexicon before demonstrating the heating pattern of the unit that comes from the bottom of the diffuser. Below Right - The heating pattern of the Solar Plexicon is displayed.

Introducing the Solar Plexicon - The Next Phase in Solar-Powered, Energy-Harvesting Products from Titus Displacement ventilation is growing in popularity as engineers and design professionals seek to use air distribution systems that are ultra efficient and occupant friendly. The benefits of displacement ventilation include energy savings, and the highest level of indoor air quality (IAQ) of any HVAC system in the market. An additional factor, the cost of the system, is also driving the decision process toward displacement. One reason cost has become so important is the fact that more and more designs with displacement ventilation are also calling for a supplementary heating system as well. Since heating from a traditional displacement system is not possible, providing a second HVAC system to heat the occupied space presents challenges on the cost, design, and installation sides. To provide a solution, Titus developed the solar Plexicon dual function diffuser. The solar Plexicon addresses the heating problem by incorporating two air distribution delivery methods - stratified and mixed ventilation, into one diffuser assembly with a single supply duct connection. The solar Plexicon uses displacement principles to cool and mixed airflow principles to heat the occupied space. The design features two separate internal plenums that provide separate air passage

14 On Air | WINTER 2012 EDITION

ways for cooling and heating. The front plenum is ducted to a DVRI face to provide displacement cooling. The rear plenum in the unit is ducted to a CT diffuser located at the bottom of the diffuser to provide heating from the floor level. Pattern controllers were added to the CT to provide additional spread in heating mode. The result is a unique dual function diffuser that provides an optimum level of cooling and heating per ASHRAE without the need for a secondary heating system. To power the auto-changeover action when changing to the cooling or heating mode, the solar Plexicon utilizes the same wireless, energy-harvesting platform that is found in the EOS solar diffuser. The energy-harvesting process that drives the auto-changeover function is achieved by using solar light energy to power the unit. Two miniature motor/actuator assemblies are mounted internally and connected to dampers. www.titus-hvac.com | www.titus-energysolutions.com

Each assembly is powered by solar panels mounted on the unit that gather sun and ambient room light and stores the energy on a capacitor. An internal circuit board houses the energy storing capacitor, temperature sensing device, and specially programmed algorithmic logic to regulate actuation changeover time and sequence. The unit “wakes up” every 10 minutes to check the room and supply air temperature and logs both. When an air temperature is recorded out of the pre-set dead band, the smart logic instructs the diffuser to change the blade position for either heating or cooling. If the temperature that is recorded calls for heating, the logic instructs the actuator to direct the airflow to the CT diffuser for mixed airflow heating. If the temperature that is recorded calls for cooling, the logic instructs the actuator to direct the airflow to the DVRI face for low velocity displacement cooling. The solar Plexicon is designed to operate with all types of HVAC systems in the market (single duct, dual duct, fanpowered, DX, etc.). To accomplish this, the unit was created with a narrow temperature band for the cooling and heating changeover actuation. The default values for the band are 78 degree F. for heating and 71 degree F. for cooling. In addition, the changeover set-points are adjustable. Each default set-point can be adjusted in one 2-degree increment up or down. This provides maximum flexibility by allowing www.titus-hvac.com | www.titus-energysolutions.com

the installing contractor to customize the band to fit any type of HVAC system they may be using. At the narrowest point, the band can be adjusted to 73 degrees F. for cooling and 76 degrees F. for heating. The band can also be expanded to 11 degrees or shifted up or down in 7 degree increments depending on system requirements. The benefits of the Plexicon unit can be seen throughout the building process. Design engineers don’t have to worry about designing and integrating a secondary system for the heating requirements. This saves valuable time and energy during the planning and design phase. Contractors can save time and money since they don’t have to install a secondary air delivery system that includes additional ductwork, diffusers and controls. The building owner doesn’t have to pay for the second system which saves money on the overall project. Finally, the building occupants can enjoy the highest level of thermal comfort and indoor air quality delivered by low velocity displacement cooling, or mixed airflow heating from the floor level. With the solar Plexicon, Titus continues to provide “Clever, Creative, Comfort” in a new and innovative way.

JAMES GRAY On Air | WINTER 2012 EDITION

Displacement Ventilation Selection Software Now Available in TEAMS Designing a displacement ventilation system comes with its own set of challenges. Bringing cool air directly into a space at floor level makes for new questions and problems to be solved if the occupants are to be comfortable and the benefits of displacement are to be realized. Titus is proud to now provide a tool to address these challenges – our new displacement selection software. The goal of our program is to quickly help the designer in finding the right product that will: ◊ Minimize the CFM required to provide cooling. ◊ Insure that stratification does not exceed standards for comfort. ◊ Maximize the comfortable or usable floor space. Our software accomplishes these goals using new calculations, data and features designed specifically for displacement ventilation (DV). ROOM AIRFLOW COMES FIRST With overhead air distribution, we often use a favorite diffuser based on the pattern and the air volume with little regard for what is happening in the room as a whole. But in DV, it helps to look at the room airflow holistically. Displacement Ventilation principles depend on setting up a proper stratification throughout the entire room volume. Our

16 On Air | WINTER 2012 EDITION

software reflects this principle by getting the room airflow properties settled first. The room-level properties include dimensions, desired temperature, CFM, cooling loads, supply temperature and gradient. These properties must be determined before any devices or specific models are considered or selected. To accomplish these room-level calculations, we offer up two distinct methods in the program: Airflow-based Calculation: this is the well-understood method of determining CFM and the delta-T required to match a sensible load. Load-based Calculation: Different types of loads in a space impact the occupied zone to differing degrees. ASHRAE research has provided a method for us to discount portions of some loads to the degree they don’t impact the occupied zone. An engineer can enter the room loads as determined from their load program. Our software will apply the proper treatment for each load type. This method often requires less CFM than the airflow-based method which adds up to energy savings. AUTO SELECT GIVES CHOICES Once the room airflow properties are settled, the Auto Select feature will display a list of various DV models and sizes. Each www.titus-hvac.com | www.titus-energysolutions.com

line item shows a different product option to accomplish the same task. Each will distribute the same total room airflow. This enables the user to quickly narrow down the models & sizes that make for a good application. The Auto Select results are sorted by the Comfort Area value. Comfort Area is simply the percentage of the room floor area that is outside of the adjacent zone(s). The higher the Comfort Area, the more floor space is useful for extended occupancy. DEVICE POSITION Clicking on one line in the Auto Select table will then switch the user to the Device Position panel. Here the user can drag, drop and rotate each diffuser diagram to match the desired layout in the room. Using this scaled diagram, the designer can use knowledge of occupant and furnishing location to best locate the individual diffusers.

ISOVEL VIEW Finally, the Isovel View shows the top view of adjacent zones for each diffuser in the room, all to scale.

ROB COPELAND On Air | WINTER 2012 EDITION

In Memoriam Bob Langmade July 4, 1924 - May 30, 2011

n May 30th 2011, the HVAC industry lost one of the greats, Bob Langmade, the President of the Norman S Wright Co.-SW, died at the age of 87 after a ten year battle with cancer. His last day of work was earlier in the month of May. Bob was born July 4th, 1924 to Pearl Louise and Robert Grover Langmade in Phoenix, Arizona. Robert attended Phoenix Union High School, graduating in 1942. He entered the US Navy in April of 1943 and served as an aerographer in the Aleutian Islands near Alaska. At the end of WWII, he married his high school sweetheart and embarked on an adventure that would last 64 years. He continued his education graduating from Phoenix Community College. Together, they enrolled at the University of Colorado, both graduating in 1949 with degrees in Architectural Engineering. Upon returning to Phoenix, Bob first went to work for Tucson Steel. In 1952, Norman Wright Jr. hired Bob to open an office in Phoenix and Norman S. Wright & Co SW was formed. In order to serve the Southwest, offices and warehouses in Tucson, Albuquerque, and El Paso were formed. In the late 1970’s, Norman Wright Jr. retired and Norman S. Wright & Co. SW became a separate organization from the original company in San Francisco. In the late 1970’s Bob completed the purchase of the Southwest Companies. The business became a passion for Bob, who poured his heart and soul into the company and the HVAC community. Today, under current principals Dianne Langmade (Daughter), Bob Schmidt, Tom Watters, Tim Murphy and David Gallegos, the four locations now have over 57 employees and over 77,000 square feet of warehouse space. Bob was also instrumental in starting both Metal Form Manufacturing, a manufacturer of HVAC products with worldwide distribution, and Longmeadow Properties. His children are now managing both of these companies. According to Leon Kloostra, Senior Chief Engineer at Titus, who knew Bob for over 40 years, “Bob behaved with honor and integrity throughout his life and never lost his sense of curiosity”.

Above - Don Titus (above left) poses for a photo with Bob Langmade (above right). The photo was taken back in 1979.

Norman S. Wright Co.-Manufactures Representatives and Titus have been partners since the early 1960’s, making Bob Langmade one of the longest Titus Representatives in the Company’s history. Throughout his life Bob, was an active part of the community, a member of ASHRAE, the Optimist Club, and a Leader of Boy Scout Troop 22. He was also an avid tennis player, an outdoorsman, and a dedicated father. His wife of 64 years, Beatrice, three children Dale, Dan, and Dianne all residing in Phoenix, and five grandchildren survive Bob.

Time for a Change, the New Website Launches Evolution is defined as a gradual process in which something changes into a different and usually more complex or better form. To be more specific, evolution is the process of development and that is the approach we have taken with the design of our new Titus website. The new look and feel of the website is a direct reflection of the growth, change and energy that is being felt throughout our company today. The feedback we have received since it launched in November has been overwhelmingly positive and we owe a great deal of thanks to our reps for their input in helping us create the website you see today. While keeping navigation and links virtually the same with only a few tweaks, we were able to build a faster and more efficient interactive resource to meet your needs. Compared to its predecessor, the new website offers a more advanced e-catalog interface that has high quality images of our products, installation photos and detailed information pertaining to each product. The interface at the model

level remains broken up into six main categories: Catalog, Performance, Literature, Submittals, Case Studies, and Multimedia. Instead of the menu being vertical, it is now horizontal which offers a plus. Now the user has everything in front of them and no longer has to scroll for documents. Within each category, documents and videos are loaded and associated with each product to provide you everything you need related to the product you have searched. Some additional areas within the site that received significant upgrades are Titus University, the Literature section and the Spotlight sections on the home page. Titus University is a frequently visited location on the Titus website. Training information, class schedules and objectives can be found as before, but this new website also contains extensive information about our new state-of-the-art lab. Each room is featured and provides a synopsis about the design and testing that can be done within the facility. One consistent piece of feedback we received was that we needed to improve the literature we make available online. This newly designed area www.titus-hvac.com | www.titus-energysolutions.com

The new Titus website launched in November of 2011. Faster search results, a new e-catalog interface and better installation photos are just a few benefits users experience. Future enhancements include: Social media presence, a Titus YouTube channel and so much more.

highlights the following: Catalogs, Presentations, Manuals, Flyers, Brochures and Case Studies. The majority of the literature is new and provides more details into the product. This section will always be updated with new and exciting information related to our products and services we offer. Finally, the enhancements made to the home page spotlight areas provide us significant opportunity to not only highlight a specific product, but also highlight a particular project that features our products. As with any new website, there will always be opportunities for improvement. We are aware that there are areas that we can enhance and make even better which is why we decided to roll it out in phases. Phase I, launched the website and laid the foundation for us. Phase II, will enhance and strengthen our interactive HVAC resource by making proactive adjustments and changes as needed. And finally Phase III, we complete our website and further cement Titus’s place as the true leader in the HVAC industry. For instance, one area that has been brought to our attention is the need for more social www.titus-hvac.com | www.titus-energysolutions.com

media on the website. Our social media presence is currently limited to Facebook and LinkedIn on the website, however in the coming weeks that will soon change significantly. We have been diligently working to correct this and have created virtually everything we need to implement this soon. It’s very possible that this area could be tweaked by the time this edition of On Air is printed. Additional enhancements include the following:

• • • • • •

A Titus YouTube Channel. Complete social media presence. PLOP search field. Titus Blog on several different topics. More Product smoke video demonstrations. And so much more.

The Results are in, RP-1335 Test Effects of Typical Inlet Conditions on Ceiling Diffusers and their Performance is Complete In our Fall 2009 Edition of On Air, we briefly mentioned that ASHRAE Study 1335 on the effects of typical inlet conditions on ceiling diffusers and their performance was underway at the University of Nevada, Las Vegas (UNLV) laboratories. The study was proposed to ASHRAE TC-5.3 (Room Air Distribution) research committee by me, and I also served on the project monitoring committee. The goal of this ASHRAE study was to test and determine the impact on manufactures catalog performance data for ceiling diffusers created by typical field-installed inlet conditions. ASHRAE Standard 70-2006, is the current “Method of Testing the Performance of Air Outlets and Air Inlets” used by manufactures to obtain catalog performance data. Standard 70 requires diffusers to be tested with a minimum of 3 diameter equivalents of straight duct ahead of the inlet with even flow throughout the duct. So the question is, “What happens when diffusers are mounted in buildings and how much variation in performance will we see with typical field installed conditions?” When building air distribution systems, designers and system installers require accurate quantitative information on how the installed system will perform to achieve optimum efficiency and comfort, and they rely on performance data from manufactures catalogs. But catalog performance reflects perfect inlet conditions. If field installations adjustments are required to the manufactures data due to typical field installation procedures, the extent of these adjustments to the performance data of throw, pressure loss, and sound will be shown in the results of this study.

26 On Air | WINTER 2012 EDITION

FlexRight - A brace designed to shape flexible ducts into highly efficient 90 degree elbows at the diffuser inlet. This study incorporated the performance data of multiple installations using six different types of typical ceiling diffusers. The data in this report compares the performance results of these various field installations to the performance data collected per ASHRAE 70-2006. All diffusers were first tested per ASHRAE 70-2006 to determine the base performance data and then various modifications to the installation were conducted. Full scale testing was done in the UNLV laboratory with diffusers mounted in various inlet conditions over a large range of flow rates with various duct approach angles, as well as: ◊ hard duct vs. flex duct ◊ various straight duct heights above the diffuser ◊ using an elbow attached to flexible duct ◊ close coupling duct installations In addition, the effect of various dampers connected directly to the diffusers with multiple inlet conditions was also studied.

www.titus-hvac.com | www.titus-energysolutions.com

SIGNIFICANT RESULTS SHOW DUCT CONNECTIONS Installations with flexible duct connections and tight bends affect diffuser performance significantly due to uneven air flow through the diffusers. THROW The throw from the diffuser is affected with elbows directly attached to the diffuser inlets. The throw from the a diffuser with an 90 degree elbow directly attached to diffusers of all types tested showed an average throw increase in the (forward) direction and a decrease in the (backward) direction. Dampers, depending upon the design, can reduce this asymmetry problem a significant amount. These dampers, however, also add a significant sound increase. PRESSURE LOSS The data shows that a flexible duct elbow to a diffuser as compared to an all metal elbow has a greater pressure loss. This data also shows that the higher the pressure loss of the diffuser, the less the effect of inlet conditions and damper conditions. The average pressure loss increase due to dampers on the face of diffusers is about 50%. This data shows that dampers directly mounted on the diffuser inlet should be avoided.

to those seen with elbows to diffusers. Another variable was also seen which deals with the main duct velocity and the pressure loss of the diffuser as related to the velocity pressure in the main supply duct. In general, as the main duct velocity increased greater than the diffuser inlet velocity, the sound from the diffuser increased. Once again, open dampers also increased the sound. DAMPERS In general, the data show that dampers should be mounted as far up stream form the diffusers as possible. Dampers directly mounted on diffusers cause high velocity air streams on the diffuser cones and can cause significant sound increases. RESOLUTION As part of the report, a set of tables were developed to easily predict how various installation configurations will affect diffuser performance. A set of three reports will be given at the Winter ASHRAE 2012 meetings in Chicago, and copies of this data may be purchased at the time of these meetings.

SOUND A very interesting group of information deals with the amount of straight duct required after an elbow to obtain the same performance data as shown in manufactures catalogs. This data shows that three diameters of straight duct downstream from the elbow typically resulted in the same sound levels as cataloged and tested by ASHRAE 70-2006. However, elbows directly connected to diffusers typically increase the NC. Dampers also contribute to sound increases. Dampers in the full open condition can add to NC levels. Flex duct elbows averaged higher than rigid duct. The sound data from plaque diffusers was interesting. This data showed that with a fixed diffuser face free area as we have with plaque diffusers, that the increase in sound is not as critical as compared to diffusers of this type with inlets having a greater free area than the diffuser face. CLOSE COUPLING OF DIFFUSERS Close coupling is when diffusers are connected directly below a ducting system. The length of duct between the supply duct and the diffuser was studied. The results were very similar www.titus-hvac.com | www.titus-energysolutions.com

At that time Titus recognized that Mussun was an exceptional rep in the Cleveland, Akron & Youngstown markets. Now 55 years later, after another record year, Mussun has again proven to be a remarkable partner and friend to Titus. Mussun currently represents the Cleveland, Akron, & Columbus regions. Per Terry O’Brien, Vice President of Mussun Sales, since our companies founding in 1951, “We have always prided ourselves on being the premier representative, representing

28 On Air | WINTER 2012 EDITION

the premier lines in the industry, and Titus has always been our #1 line.” Over the years, Mussun’s commitment to excellence has remained resilient while they have also adapted to the changing needs of their customers. In response to various business demands, Mussun moved in 1993 to a 50,000 square foot headquarters on Carnegie Avenue in Cleveland. They also have rep offices in Columbus, managed by Ward Weber II, and Akron managed by Jeff Stamler. They have grown their business to include many additional product lines and are currently one of the largest manufacturer’s representatives in Ohio. They offer a complete HVAC package to their market. The large capacity of their warehouse enables Mussun to offer same day pick up for a wide variety of HVAC products and is a staple of their success in their region. In addition to Mussun’s stellar reputation in the market and their record Titus sales for 2011, there is evidence of Mussun’s success virtually everywhere you go in their territory. Mussun has supplied material on most of the major buildings in their region. These include the Key Tower, the Rock & Roll Hall of Fame, the Great Lakes Science Center, the new Public Library, the Federal Reserve Bank, and the Federal Courthouse. In www.titus-hvac.com | www.titus-energysolutions.com

“We have always prided ourselves on being the premier representative, representing the premier lines in the industry, and Titus has always been our #1 line. - Terry O’Brien”

addition, they have provided materials for the entire Gateway Project including the Quicken Loans Arena and Progressive Field, the Cleveland Browns Stadium, the Nationwide Arena, and the Ohio Stadium in Columbus. More recently they supplied product for the Cleveland Museum of Art, the Cleveland Clinic, the University Hospital, the Cleveland State University, the Cleveland Playhouse, the Horseshoe Casino in Cleveland, and the Hollywood Casino in Columbus. Clearly, they have a very impressive list of prominent, renowned projects under their belt. In the 55 years that Mussun has been selling Titus, Jeff Andres, President of Mussun Sales, has provided exceptional leadership to the company for 48 of those years. Jeff has always considered his rep lines, customers, and employees as business partners, but also as friends first. It is safe to say when it comes to Mussun, relationships are their business. Mussun helps to establish their commitment to their employees through annual events like their Cedar Point celebration and their annual Christmas party for the employees and their spouses. They also host an annual golf outing called the Mussun Open and take part in various local events with their customers. When you meet Jeff and others from Mussun, you quickly find that they go out of their way www.titus-hvac.com | www.titus-energysolutions.com

to make you feel welcome. They have a wonderful group of sales representatives and staff that is very talented and professional, but also warm and friendly. It is no surprise that Jeff is known to say, “ I never knew what a wonderful deal I had when all I had to do was get up early in the morning and go call on my friends.” This is a message that rings loud and clear throughout the Mussun culture. Relationships certainly are their thing & no doubt a critical part of their success over these many years! Mussun continues to be one of our strongest rep firms. We are extremely thankful for the opportunity to continue our partnership with a firm of their caliber. We look forward to a successful partnership for many years to come. We thank Mussun, along with all of our loyal representatives, for their contributions to Titus over the years. It is with the support of our representative firms that we continue to have the honor of being the leading manufacturer for air distribution products in the industry!

THE OHIO STATE UNIVERSITY THOMPSON LIBRARY ARCHITECT -ACOCK ASSOCIATES ARCHITECTS / GUND PARTNERSHIP REPRESENTATIVE - MUSSUN SALES, INC LOCATION - COLUMBUS, OHIO LEED CERTIFICATION - NONE

ABOUT THE PROJECT In an age where new and technologically advanced buildings are being built everyday, The Ohio State University faced a difficult decision - to demolish their existing library or renovate it. The answer was renovation and it turned out to be the correct one. The new Thompson Library was recently reopened after a three year renovation and offers many amentities that patrons would expect at new libraries. With funding from the Athletic Department, the architects at Gund Partnership and Acock Associates were able preserve the rich history of the original library and infuse it with modern conveniances from today. The renovation and expansion transforms the original library into a 309,000 square-foot building. Places to study throughout this 11-story building have drastically increased. New computers and wireless access to the internet are definite upgrades. Other amentities include a cafe for study breaks, a gallery that houses special collections of art from the library and breathtaking views of the campus and Columbus, Ohio can be found on the eleventh floor.

THE TITUS SOLUTION Titus has extensive experience in renovating outdated HVAC systems into new efficient systems that help save energy. We were able to supply this project with an assortment of grilles and diffusers that not only blend well architecturally, but provide superior performance. TDCA diffusers handle an unusually large amount of air for a given pressure drop and noise level. Their pleasing appearance

It also has an adjustable air discharge pattern and maintains an unbroken horizontal flow pattern from maximum cfm down to minimum cfm. The TDCA is truly an excellent selection for variable air volume systems. The 50F is an Eggcrate grille that has one of the highest free areas of any return grille. These grilles are available with an aluminum border and aluminum grid; a steel border and aluminum grid; or entirely stainless steel construction. It is offered in ½ x ½ x ½-inch, ½ x ½ x 1-inch, or 1 x 1 x 1-inch core sizes. The 50F is also available as a filtered return grille too.

diffuser is also available in 1-, 2-, 3-, and 4-slot configurations. Finally, Titus’ 300 / 350 series grilles define the standard for the HVAC industry. With high quality and competitive pricing, these grilles form the back bone of a standard offering that will meet any application requirement.

THE END RESULT The new William Oxley Thompson Library is now a library that students, faculty, and staff can be proud of for quite some time. This renovation begins a new era of learning for the university.

The Titus ML Modulinear diffuser is a high performance, high quality linear slot diffuser. Its unique “ice tong” deflector blades allow for both changes in air volume and direction from the face of the diffuser. Modulinear diffusers are designed for variable air volume systems. They project a uniform blanket of air that adheres to the ceiling even at low flow rates. This www.titus-hvac.com | www.titus-energysolutions.com

Adjacent Zone vs. Clear Zone - the Real Debate Begins

n page 8 of this edition of On Air, the article on ASHRAE Standards 55 and 62.1 summarizes ASHRAE’s standards for thermal comfort and minimum ventilation and explains how to apply air outlets to comply with each of these standards. Even though the article also references the definition of the ‘adjacent zone’ that exists in close proximity to Thermal Displacement Ventilation (TDV) diffusers, it’s also important to understand how Titus displacement ventilation products differ from the competition with respect to occupant comfort. To briefly recap, displacement diffusers used in fully-stratified systems deliver low velocity cooling directly to the occupied zone. Since the supply air is cooler than the room air, it cascades down the face of the diffuser and travels across the floor in a thin layer generally no more than 4 inches deep. The ‘adjacent zone’ is defined as any portion of the room where discharge velocities exceed 40 fpm. This area is not recommended for stationary occupants who would likely feel a chill around their ankles. Although displacement ventilation diffusers are available from most manufacturers in a myriad of shapes and sizes, there are really two basic types of designs being manufactured: • Fixed Air Pattern • Adjustable Air Pattern Although all displacement diffusers include a perforated face plate and a rear supply plenum, fixed air pattern diffusers are characterized by a perforated central baffle. The purpose of the central baffle is to further slow and spread the supply air evenly over the face plate. Diffusers of this design are less costly to produce but they must be selected very carefully to ensure that the symmetrical adjacent zones they create will not result in thermal discomfort for stationary occupants. Fixed air pattern diffusers also lack versatility in situations where spaces are being reconfigured or re-purposed.

Titus DVHC displacement ventilation diffuser cutaway view that shows the innovative adjustable pattern controllers. air pattern diffusers include a baffle fitted with air pattern controllers. These sturdy steel pattern controllers are easy to remove and reset and do not raise concerns about plastic materials in the air stream. Although these pattern controllers ship out of the factory in a default arrangement to create a standard symmetrical discharge pattern, they provide adjustability for enhanced versatility and improved occupant comfort. Rather than settle for a fixed discharge pattern, Titus displacement ventilation products can be easily adjusted to direct air away from occupants and areas that may result in comfort issues (now or in the future). Titus displacement ventilation products include adjustable pattern controllers so that you can control your ‘adjacent zone’.

Grille Performance Data QUESTION: How do I get performance data for grille sizes that are not published in the Titus catalog? ANSWER: The Titus selection software program, TEAMS, which is available as a free download from the Titus website, contains many grille sizes not published in the catalog, and allows the user to input air volume (CFM) in increments other than those published. Should TEAMS not be available, the following method should be used. 1. Determine the nominal duct area in square inches by multiplying the nominal length and width of the desired grille size in inches. E.g. 64 x 10 = 640 square inches

2. Convert the duct area from square inches to square feet by dividing the total square inches by 144 and rounding to a 2-place decimal. E.g. 640 square inches / 144 = 4.44 square feet 3. Locate a published grille size in the catalog for which the nominal duct size is approximately the same. The nominal duct area in square feet is the column directly to the right of the listed nominal duct sizes. E.g. 4.44 square feet approximates to the 4.50 square feet shown for a 36 x 18 supply grille, and is less than is less than a difference of 2%. Duct leakage often accounts for more of a discrepancy than 2% in terms of performance. 4. Locate the nearest approximate desired volume listed for the approximated grille size. E.g. A desired volume of 2300 CFM falls approximately midway between the listed volumes of 2110 and 2532, therefore the median throw and NC values between the values for 2110 and 2532 should be used. The median value of NC 23 and 28 is 25 after rounding to an integer value.

The median values of the 0 degree deflection values 39-5984 and 47-65-93, are 43-62-88. QUESTION: I need performance for an oversize grille and I canâ&#x20AC;&#x2122;t find a duct area that matches, so how do I get performance for that? 1. Divide the duct area by two or more until you find a comparable duct area, and then multiply the throw by 1.4, this is a common constant for the adjustment in total air mass that is used for extrapolating throw performance. This conversion factor is also used in all of the linear diffuser conversion charts. 2. A good rule of thumb on sound is to increase the sound data by 3 NC to obtain a cumulative value.

Vertical throw for supply grilles is not usually required since grilles mounted in a ceiling are not a normal application. But it sometimes happens and diffusers can be set to throw vertically. The method of obtaining throw data is as follows. 1. Determine the flow rate in CFM and the jet velocity from the published horizontal throw data pages. 2. Refer to the engineering section of the Titus catalog; page B24. Find the sections entitled Estimating Downward Vertical Projection. 3. Using the table in Fig. 24, find the vertical line representing your flow rate in CFM. 4. Follow the vertical line to the jet velocity curve that corresponds to core velocity listed in the published data. 5. Project a horizontal line from where the vertical flow rate line intersects the velocity curve to the column on the right hand side of the figure. 6. Select the appropriate temperature differential (delta T) column and read that vertical distance.

New GRD Product Update As we continue to expand our product line to address market needs and provide a competitive edge, we will be introducing some new products in January 2012. The new products include a redesigned architectural diffuser, an EOS masterdrone option, a new wireless energy harvesting diffuser and an architectural linear diffuser for the Armstrong Techzone ceiling grids.

New OMNI-RS Design Architectural grilles and diffusers have seen significant growth in our industry as architects and design professionals are demanding products that perform well and have great aesthetics. To address the growing popularity of this segment, Titus has redesigned the OMNI-RS diffuser. The new design utilizes the OMNI/TMS stamped backpan which results in numerous improvements over the old design. These include more inlet options, seven border types – including narrow tee (NT), and 24” x 24” and 12” x 12” module sizes. The new design also features improved performance which makes this diffuser an excellent choice for VAV (variable air volume) applications.

EOS Master Drone The EOS master-drone diffusers are the second generation of the revolutionary EOS energy harvesting diffuser introduced in December 2010. The new EOS master-drone product is designed to offer a cost effective alternative for applications with two diffusers mounted within a 12 foot distance of each other on perimeter areas of buildings. The EOS standard unit has been modified to operate as a stand-alone unit or a master in a master-drone configuration. All EOS standard units are shipped with a molex connector for connection to the drone. All drone units are shipped with a factory mounted 12’ cable for connection to the standard unit. To operate as a master-drone setup, simply order the EOS standard and drone units, connect the drone cable to standard unit, and set the temperature set-points for each unit. The standard unit will automatically detect the drone unit and start the masterdrone operation mode. Drone units can be added after the standard units are installed which provides a high level of flexibility when space designs change.

Solar Powered Plexicon Diffuser Earlier this year, Titus introduced the Plexicon heating/ cooling displacement diffuser for applications that require displacement cooling and perimeter heating from the same diffuser assembly. The Plexicon is a line powered unit that requires external power to operate the motor/actuator for the auto-changeover action between heating and cooling. In January 2012, we will introduce a solar powered, energy harvesting version of the Plexicon that requires no external power to operate. The new solar Plexicon will utilize the same wireless, energy harvesting platform and smart logic that was developed for the EOS solar diffuser. In addition, the solar Plexicon will feature the same narrow and adjustable temperature as the EOS – so it will operate with all types of HVAC systems in the market (single duct, dual duct, fan-powered, DX, etc.). The new solar Plexicon will take displacement ventilation to a new level by offering a “net zero” energy alternative to the line powered version while providing the highest level of thermal comfort in the space.

FL-TZ Diffuser for TechZone Grids Titus has always been a pioneer in the industry by partnering with outside vendors to develop products that are application driven. A good example is our relationship with Armstrong Industries that began in 2008 with the introduction of the ML-TZ diffuser for Techzone style ceiling grids. The ML-TZ has been an extremely successful addition to our product line with over $1.6M in sales. We want to build on that success by offering a new architectural diffuser designed specifically for Techzone style ceiling grids. Available in January 2012, the new FL-TZ utilizes the FlowBar FL-10 design with high throw or jet throw pattern controllers and is designed to fit both standard lay-in and narrow tee grid sizes. The unit is available in 4-inch and 6-inch widths and 1 or 2-slot configurations and utilizes the standard FlowBar distribution plenum. With superior performance and great aesthetics, the FL-TZ diffuser is an excellent choice for Armstrong Techzone ceiling grids.

Liner Specifications and Standards

he choice of lining material for any air distribution system is an important consideration for the specifying engineer. There are many options available and each material has a potential impact on project cost, thermal performance and acoustical performance. While the traditional lining materials in the industry have been fiberglass-based, there are other alternatives available today. These new materials have many advantages from the standpoint of physical properties as well as cost and performance. In order to successfully promote these new materials, itâ&#x20AC;&#x2122;s helpful to have a better understanding of current industry standards and how they are applied.

xx ASTM C518 - Standard Test Method for SteadyState Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus

There are several agencies that set standards for the ductwork and equipment lining materials. They include American Society for Testing and Materials International (ASTM), National Fire Protection Association (NFPA) and Underwriters Laboratories Inc. (UL). While most of the standards they publish must be purchased and can be costly to acquire, in order to determine whether a material is in compliance it is often not necessary to know more than the title of the standard. Here are some of the most frequently referenced standards:

xx ASTM C1104 - Standard Test Method for Determining the Water Vapor Sorption of Unfaced Mineral Fiber Insulation

xx ASTM C411 - Standard Test Method for Hot-Surface Performance of High Temperature Thermal Insulation

40 On Air | WINTER 2012 EDITION

xx ASTM C665 - Standard Specification for MineralFiber Blanket Thermal Insulation for Light Frame Construction and Manufactured Housing xx ASTM C739 - Standard Specification for Cellulosic Fiber Loose-Fill Insulation xx ASTM C1071 - Standard Specification for Fibrous Glass Duct Lining Insulation (Thermal and Sound Absorbing Material)

xx ASTM C1338 - Standard Test Method for Determining Fungi Resistance of Insulation Materials and Facings xx ASTM E84 - Standard Test Method for Surface Burning Characteristics of Building Materials xx ASTM E96 - Standard Test Methods for Water Vapor Transmission of Materials xx ASTM G21 - Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi

www.titus-hvac.com | www.titus-energysolutions.com

xx ASTM G22 - Standard Practice for Determining Resistance of Plastics to Bacteria xx NFPA 90A - Standard for the Installation of Air Conditioning and Ventilation Systems xx NFPA 90B - Standard for the Installation of Warm Air Heating and Air Conditioning Systems xx NFPA 255 - Standard Method of Test of Surface Burning Characteristics of Building Materials xx UL 181 - Standard for Factory-Made Air Ducts and Air Connectors xx UL 723 - Standard for Test for Surface Burning Characteristics of Building Materials These standards are commonly referenced in equipment specifications, and most of them only cause confusion. The first thing to note is that each of these standards is either a test method or specification. Test methods define a procedure for measuring a physical property associated with a material. These procedures are often material specific. Specifications (often simply titled as Standard) generally reference several acceptable test methods and set maximum or minimum limitations on the result of a test for compliance. In order to determine compliance with a specification requirement, it is important to note whether the referenced standard is an actual specification or just a method of test. Since there’s no way to comply with a test standard, the inclusion of test standards in a specification often causes confusion for vendors. Another common problem involves specifications that describe a specific lining material but reference standards that do not apply to that specific material. All of these issues can be identified and clarified by simply knowing the full titles of the referenced standards. In addition to the aforementioned ASTM, NFPA and UL standards, there are additional industry standards published by the Air-Conditioning, Heating and Refrigeration Institute (AHRI), American Society of Heating, Refrigerating and AirConditioning Engineers (ASHRAE), and U.S. Green Building Council (USGBC). Traditionally, ASHRAE publishes test standards for equipment and guidelines for environmental conditions such as ventilation, indoor air quality and thermal comfort. AHRI concentrates mainly on equipment ratings and performance certification. USGBC publishes the Leadership in Energy and Environmental Design (LEED) standard. Since most new construction projects will be designed with a goal towards achieving LEED certification, it’s important to know what the USGBC requirements are for ductwork and equipment linings. According to the latest LEED 2009 standard, in order to achieve Indoor Environmental Quality (IEQ) Prerequisite 1, the building design must meet the minimum requirements of Sections 4 through 7 of ASHRAE Standard 62.1-2007 Ventilation for Acceptable Indoor Air Quality. Under Section 5 ‘Systems and Equipment’, it states that all airstream surfaces (with the exception of sheet metal www.titus-hvac.com | www.titus-energysolutions.com

surfaces and metal fasteners) shall be determined to be resistant to mold growth in accordance with a standardized test method such as those found in UL 181 or ASTM C1338. In addition, all airstream surfaces (with the exception of sheet metal surfaces and metal fasteners) shall be determined to be resistant to air erosion in accordance with the test method described in UL 181. In other words, any lining material that can meet the requirements of UL 181 is acceptable for use in any LEED-certified building. Here are some typical questions about liner specifications and standards: Does that mean I can put exposed dual density fiberglass in a LEED Platinum building? Yes, it does but just because dual density fiberglass is allowed doesn’t mean it’s the best choice. Many engineers On Air | WINTER 2012 EDITION

are looking for alternatives to fiberglass because no one knows how that material may be treated in the future. Today there are innovative new lining materials that can provide improved indoor air quality with little if any increase in cost. What kind of ‘new liners’ are you talking about? Titus has seized the initiative to begin the elimination of fiberglass from our many product lines. We currently offer our latest EcoShield liner in 1/2” or 1” thickness with cloth facing for the same price as fiberglass. This material is made from pre-consumer recycled natural cotton fibers chemicallytreated to be fire retardant and anti-microbial. The same material is also available with a scrim-reinforced foil facing for critical environmental applications for a modest up-charge. We also offer our FibreFree liner in 3/8” or 1” thickness. This material is called engineered polymer foam insulation (EPFI). It contains an anti-microbial agent throughout to fight mold growth and cannot absorb any moisture making it ideal for humid climates and applications where moisture can cause problems. I submitted EcoShield on a project recently, but was rejected by the engineer because I couldn’t prove that this material meets ASTM C1071. Why doesn’t EcoShield meet ASTM C1071? EcoShield technically cannot meet ASTM C1071 because that standard only applies to fiberglass products. That doesn’t mean that EcoShield isn’t suitable as a duct lining material,

42 On Air | WINTER 2012 EDITION

because it may actually outperform fiberglass in the same tests. The engineer’s standard specification probably only takes into account fiberglass products and doesn’t address the new liners available today. I would suggest providing EcoShield submittal sheets, explaining the advantages and encouraging him to update his standard specification to include newer materials. So long as the lining materials meet UL 181, they should be acceptable. With a better understanding of the industry standards, it should be easier to promote new and better lining materials to the engineering community. I hope you find this information helpful.
