End Reflection Calculation and the New Titus Catalog
![]() |
My new Titus Catalog |
On January 1, 2012, AHRI 880 started requiring that discharge sound power data for terminal units from all manufacturers be adjusted to include end reflection. Everyone in the industry has updated their catalog data when they printed their new catalog. This change is reflected in the new 2014-2015 Titus catalog.
End reflection is sound that is reflected back to the source from the discharge duct termination in the sound chamber. This sound cannot be measured, it can only be calculated. According to ASHRAE research, the end reflection loss can be calculated based on the dimensions of the discharge duct. This calculated end reflection loss (not to exceed 14 dB) must then be added to 1/3 octave band sound data in order to make the correction.
This change was made to correct the fact that room noise criteria (NC) ratings based on AHRI 885 include an end reflection deduction, when in fact the end reflection losses were never included. The end result is that catalog discharge sound levels (both sound power and NC) on all ducted terminal units increased even though the products have remained unchanged. The changes are most noticeable on units with smaller discharge ducts.
So as you look at terminal unit discharge data, be aware that the change in AHRI 880 has changed the sound numbers. If you are comparing catalog sound data from two different manufacturers, it is especially important that you make sure both catalogs have made the update (or both have not) so that you are not comparing one unit's pre-update data to another's post-update data.

Changes in LEED v4 that Affect Air Distribution
Last fall at the Greenbuild show in Philadelphia, the USGBC
rolled out the latest version of the LEED rating system, called LEED v4. There
are some significant changes in LEED v4 from the credit categories to the
specific credits themselves.
First, the credit categories were changed a little. Two new
categories were created: Integrative Process and Location & Transportation.
Many of the Location & Transportation credits came from the Sustainable
Sites section of the previous version of LEED. The Water Efficiency section did
not change much, but did get a couple new credits and prerequisites.
Many of the credits that pertained to Titus products were
eliminated or combined with other credits to form new credits. The Materials
and Resources section was changed the most of all the sections. Only the
Storage and Collection of Recyclables prerequisite and the Construction Waste
Management credit were not changed much.
For instance, the most common questions we receive with
respect to LEED is whether we meet the requirements of the Recycled Content and
Regional Material credits. These two credits are replaced with Building Product
Disclosure and Optimization—Environmental Product Declarations and Building
Product Disclosure and Optimization—Sourcing of Raw Materials.
Both Building Product Disclosure and Optimization credits
are designed to encourage the use of products and materials for which
life-cycle information is available and that have environmentally,
economically, and socially preferable life-cycle impacts. The Environmental
Product Declarations covers the old Regional Material credit, but instead of
defining regional as a 500 mile radius, it uses a 100 mile radius. The Sourcing
of Raw Materials covers the old Recycled Content credit. This new credit
requires that 25% of the building products meet one of several requirements,
one of which is that it is recycled.
Many of the credits in the new Materials and Resources
section are based on disclosing information related to environmental and health
impacts of products going into the building and the life cycle of these
materials.
Several credits in the Indoor Environmental Quality section
were combined into new credits. We frequently received questions about the
paint on our diffusers and the glue for our VAV box liners and whether they
complied to the Low Emitting Materials Paints and Coatings and Adhesives and
Sealants credits. These are now combined into one credit called Low Emitting
Interiors. The new credit is more specific about the paints and adhesives being
applied on site, so the paint and adhesives applied to our products at the
plants are more clearly not applicable now.
The Controllability of Systems - Thermal Comfort and Thermal
Comfort – Design credits have been combined and the Thermal Comfort –
Verification credit has been eliminated. To achieve the new combined credits, a
building must be designed to ASHRAE Standard 55-2010, Thermal Comfort
Conditions for Human Occupancy, (or ISO 7730 or CEN Standard EN 15251) and
provide 50% of the occupants with individual comfort control. Underfloor
systems and VAV diffusers are still a good way to achieve the individual
comfort control portion of this credit.
A new credit for Acoustic Performance has been added to the
Indoor Environmental Quality section as well. This credit states that room
noise levels from building mechanical systems must be within the sound level
ranges shown in 2011 ASHRAE Handbook, HVAC Applications, Chapter 48, Table 1,
AHRI Standard 885-2008, Table 15 or a local equivalent. It also has
requirements for sound isolation, reverberation time and reverberant noise
buildup, and paging, masking, and sound reinforcement systems. There are
additional acoustic requirements for schools and healthcare. For schools, it
states that the background noise level must be 35 dBA or less from the HVAC
systems in classrooms. For healthcare, the building must meet the sound and
vibration criteria adapted from the 2010 FGI Guidelines for Design and
Construction of Health Care Facilities.
The Energy and Atmosphere section is still the section with
the most possible points, primarily due to the Optimize Energy Performance
credit. The previous version of LEED had
a prerequisite of meeting ASHRAE 90.1-2007. This has been updated to require a
minimum energy performance based on ASHRAE 90.1, 2010. The Optimize Energy
Performance credit is also now based on ASHRAE 90.1, 2010. You can achieve up
to 20 points for improving the building’s energy usage from 6% to 50%. Another
method of achieving this credit is to design using the ASHRAE 50% Advanced
Energy Design Guide.
LEED v4 was a dramatically updated version of LEED. Possibly
as a response to criticisms that LEED buildings were not performing as designs,
LEED v4 has a more performance based focus than previous versions requiring
energy monitoring and reporting. It also has a stronger focus on material
transparency because, as Beth Heider, USGBC’s 2012 chair, said, “If you create
a really tight, energy-efficient building and fill it full of noxious
materials, you’ve created the perfect gas chamber.”
Titus has three LEED APs and several LEED Green Associates
to help you navigate through your customers’ questions about this new, improved
version of LEED.

Titus HVAC AHR Expo - Day 2 Coverage
We return with coverage of day two at AHR Expo 2013. Tuesday was filled with award presentations, educational
sessions, networking, training facility tours and showcasing our latest
products with the HVAC community.
We kicked off the day by proudly accepting
the AHR Expo Green Innovation Award for Solar Plexicon. It
was a proud moment as Titus HVAC’s Rob Copeland accepted the award on behalf of
the entire Titus team.
Our dedication to innovation has led to some truly exciting launches at AHR Expo 2013, including the LSC Terminal Unit that provides an alternative solution to addressing ASHRAE 62.1 ventilation requirements. The Low Profile Series (LSC) is a fan powered terminal unit that features a sensible cooling coil and is designed to work as part of a dedicated outdoor air system (DOAS).

In addition to sharing the latest products, we attended educational sessions to learn about the latest trends affecting the industry. We entered a full room during Retro-Commissioning for Existing Facilities, presented by National Environmental Balancing Bureau (NEBB).
The session began by highlighting the importance
of the topic. Nearly 66 percent of buildings were constructed
between 1960-1999 – stressing why retro-commissioning is important as there is
less new construction occurring today.
The NEBB presenter shared that all forms of
building commissioning share the same goals, including developing a building that
meets the unique needs of its owners and occupants while operating as
efficiently as possible, in addition to providing a safe, comfortable work
environment.
According to the presentation, building
performance is dependent upon ‘four legs of a stool,’ including design,
construction, commission and operation. Unfortunately, the ‘stool’ becomes
unbalanced as most buildings are not operated properly after turned over to the
owners, and because construction is driven by schedule and costs, not
performance.
The presenter shared that retro-commissioning
process should include an initial site review, pre-site investigation, thorough
plan and a post analysis to be effective in optimizing building systems, so
that comfort and costs (energy, maintenance and reliability) are optimal for
occupants and owners. Some tips include:
- Find the cause and fix it instead of reacting to symptoms
- Document any temporary measure taken and change them back as soon as the issue is resolved
- Measure performance often, includes energy and comfort
- Collect data consistently, such as utility bill or submeter data
- Compare data to baselines, including last year’s data and national database (Energy Star)
The Titus HVAC training schedule contains a
mix of free webinars, as well as Consulting Engineer Seminars, both of which
give engineers the option to earn CEU credits. As a focal point for the
classes, instructors will use the Titus Research Laboratory, dubbed “The
Comfort Zone” to enhance the learning experience with hands on demonstrations.
We wrapped up the day by sharing the new Comfort Zone with members of the trade media, who were eager to see how we will foster training interactivity with the use of touch screen technology and live demonstrations of the latest innovations in air management.

Titus HVAC Live Coverage of #AHRExpo 2013 Begins!
We had a great first day at AHR Expo 2013. The crowd was eager to see the latest in HVACR technology. Titus
booth visitors were excited to learn more about the newest Titus HVAC
advancements in air distribution. The new Titus chilled beam displacement ventilation unit, Temperature and Ambience Optimizer (TAO), captivated visitors
and kept conversations rolling between attendees and members of the Titus team.
Booth guests also had the opportunity to
experience the new Titus HVAC Augmented Reality App that
unlocks hidden content in printed Titus HVAC documentation. The free Titus AR
app allows smartphones or tablets to recognize images in Titus HVAC literature
and printed documents and augments it with hidden content like video,
animation, GPS and drawings.
For example, users can snap a picture of a piece of literature
with the incorporated Titus AR logo and view video of how to use engineering tables
or watch smoke videos of specific diffusers in print catalogs.
In addition to sharing the most recent
product advancements at AHR Expo, we spent much of the day soaking in the
latest trends, thoughts and direction of the HVAC industry during several AHR
Expo educational sessions.
We started off AHR Expo by attending, “Our Changing Industry and Connection Communities for
BAS,” presented by AutomatedBuildings.com. Jim
Sinopoli from SmartBuildings and Ken Sinclair of AutomatedBuildings.com
discussed the latest HVACR trends since AHR Expo 2012.
Sinclair kicked off the session by
stating, “Cloud computing will replace the personal computer as the ‘device’ of
choice by 2014.” He went on to explain that it has never been clearer that the
true convergence and ‘anywhere’ collaboration that we all seek will be found in
the cloud, not on individual devices.
The trend is that personal devices will
be powered from the cloud, including commercial and residential HVAC systems in
the near future.
He went on to share how he sees the
future of HVAC as becoming more open and less proprietary – meaning the
industry will grow faster as a community than it could in a segmented state.
Sinclair envisions shared applications and open standard drivers that together
will help propel the industry forward.
Jim Sinopoli built on Sinclair’s
presentation by sharing how he sees a future of smarter grid communities with
increased software applications to better manage buildings.
For example, he sees a boost in software
programs such as fault detection, energy management, mobile applications,
alarms, asset management, and preventative maintenance, among many others to
help optimize building operations.
He explained that new buildings are
increasingly becoming more complicated as training and education for operating
these complex structures lags behind.
Sinopoli believes that the training and
education community need to catch up or connected buildings will lack their
‘smart’ benefits such as solar panels, geothermal sources, wind turbines,
electrical switchable glass, exterior shading system, sun tracking systems,
energy dashboards and many others.
This wraps up our first day of AHR Expo
2013 coverage. Continue to stay tuned on our blog and make sure you are
