Everything You Wanted to Know about Integrated Energy Efficiency Ratios (IEER)

Old-timers in the HVAC industry remember the days when we rated the efficiency of equipment according to its EER (energy efficiency ratio) rating.  This was calculated by dividing the BTU capacity of a unit by the wattage consumed by it.  This was a steady-state rating however, and did not recognize a units seasonality or real-life consumption.  Therefore, AHRI (Air-Conditioning Heating & Refrigeration Institute) developed the rating we use today known as SEER.  This is calculated by taking the cooling output of a unit during a typical cooling season and dividing it by the total electrical energy input during that same time.  This rating is only applicable to units under 6 tons.

 

Larger capacity units than this were rated according to their IPLV or integrated part load value.  This was a single figure based on part load EER, designed to reflect the operating efficiency of equipment under real-world rather than ideal laboratory conditions.  On January 1, 2010 a new methodology was adopted and defined as integrated energy efficiency ratio.  (IEER) This rating methodology was developed by AHRI as an improvement for unitary equipment, and covers all units, even if single stage.  It takes into account constant fan usage in commercial applications and includes mechanical cooling operation only.  Economizer’s and energy recovery is not factored into this rating.  IEER is defined as the weighted average of a units efficiency at four load points – 100%, 75%, 50%, and 25% of full load capacity.  More specifically, this is determined as follows.

 

IEER = (.02*A) + (.617*B) + (.238*C) + (.125*D)

Where:

A = EER at 100% net capacity

B = EER at 75% net capacity

C = EER at 50% net capacity

D = EER at 25% net capacity

 

Weather modeling for cities representing 15 US climate zones was used in developing this calculation and included the percent of time operating in the four net capacity load bins listed above.  Three end use sectors were chosen, office buildings at 40%, schools at 30% and retail spaces at 30%.  The 15 cities defining US climate zones included Miami, Houston, Phoenix, Memphis, El Paso, San Francisco, Baltimore, Albuquerque, Salem, Oregon, Chicago, Boise, Burlington, Vermont, Helena, Duluth and Fairbanks.

 

This rating provides a comprehensive view of larger capacity systems, and a units IEER rating should never be compared to its EER rating.  For more information, please refer to AHRI Standard 340/360, Performance Rating Of Commercial And Industrial Unitary Air-Conditioning And Heat Pump Equipment.

 


Will We Need 92% Efficient Furnaces in Texas?

Infographic courtesy of American Public Gas AssociationIn March, 2015 the Department of Energy issued a proposed rule mandating that all furnaces will have to have a minimum efficiency rating of 92% beginning in January, 2021.   The Natural Resources Defense Council recommended that efficiencies should be even higher.   The current minimum efficiency rating required by law is 80%.  This ruling would apply to furnaces sold to distributors as of that date, the rule does not comment regarding status of lower efficiency product existing in distributor inventory.  The American Gas Association filed a freedom of information act request with the Department of Energy to find out how they justified this proposed ruling.   In addition, many industry groups and manufacturers petitioned the Department of Energy against this ruling, citing increased costs to consumers that wouldn’t be justified by energy savings, as well as existing building and energy codes and physical limitations in older or multi family structures that would make such installations virtually impossible.  The Department of Energy remained silent on all this until September, 2016 when they released a supplemental notice of proposed rulemaking.  The rule encompassed 488 pages, not including an 1198 page technical support document.  In that notice, the Department of Energy refused to back off its rule mandating minimum 92% efficient furnaces, granting only a small exemption to furnaces of 55,000 BTUH or less.  As we all know, the number of homes that would qualify for this exemption is quite small.  This ruling could even affect the manufactured housing market, as furnaces for this application are typically designed to fit in tight spaces.  In addition, this ruling will likely cause consumers to continue to repair aging equipment, which is even more inefficient than today’s standard, non-condensing furnace.

 

Many industry groups think this rule will ultimately undermine energy efficiency, because they believe many consumers, especially those in the South, will be compelled to change their natural gas furnaces to electric heat pumps.  The due date for final comments to the Department of Energy was January 6, 2017.  Nothing has been heard since.  At this point, the industry is waiting to see if the new administration vacates or mitigates this proposed rule.  If it does not, many major industry associations and manufacturers have publicly stated they will sue the Department of Energy to keep the rule from going into effect.  Stay tuned…

Will You Be among the 65,000?

If it exists in the HVACR industry, you’ll find it here!

If it exists in the HVACR industry, you’ll find it here!

Will you be among the 65,000 attendees that are expected to attend the upcoming AHR Expo in Chicago?  The world’s largest HVACR marketplace got its start 86 years ago as a heating and ventilation show, but it has grown over the years into the event of the year for the industry.  Attending industry professionals will come from every state in the union and 165 countries worldwide.  They will be joined by more than 2000 exhibitors, who will come together to share new products, technologies and ideas.  What kinds of new technologies?  Take a look at the end of this article for just a sampling.

 

This year’s event will once again be held at McCormick Place in Chicago, from January 22-24.  Most people in the industry are familiar with this Expo, commonly called “The ASHRAE Show,” but if you have never been it is hard to imagine the sheer size of this event.  When we mentioned 2000 exhibitors above, we didn’t mean 2000 people.  We meant 2000 different organizations, each coming to exhibit their company’s product offerings!  That is why this international show, held only once every four years, exhibits at the nation’s largest convention center which has over 2,600,000 ft.² of exhibition space.  Fortunately for the attendee, only about 500,000 ft.² of exhibition space will be needed for the HVACR show!  If you are looking for new product lines to boost your company’s sales, or if you’re looking to change product suppliers, or just want to do some first-hand competitive and new product research, there simply is no other opportunity like this show.  This is the granddaddy of them all.

 

Many people do not realize there is much more to this show than just the exposition.  The AHR Expo is also a major educational symposium as well.  There are over 50 free seminars offered on a wide range of topics, most lasting only 1 to 2 hours.  In addition, The ASHRAE Learning Institute will offer continuing education courses where you can choose from half day to full day professional development seminars that offer professional development hour and continuing education unit credits.

 

Finally, if you have never been to Chicago this provides a great excuse to visit a truly world-class city.  Take a stroll along the Magnificent Mile, one of the great avenues of the world, a 13 block stretch of North Michigan Ave. that runs from the Chicago River north to Oak St.  Along the way you will see the famous Chicago Water Tower, one of the few structures to survive the great Chicago fire of 1871.  From world-class museums (i.e. The Museum of Science and Industry, Shedd Aquarium, The Art Institute of Chicago, The Field Museum Of Natural History) to iconic sports stadiums (Wrigley Field) to taking in unprecedented views from atop the tallest building in the Western Hemisphere, (Willis Tower) the “City of Big Shoulders” will quickly become your kind of town.

 

Giordano’s Deep Dish Pizza

Did we mention that you can find nearly every type of food there is in Chicago, ranging from affordable to world-class cuisine?  If you are not familiar with Chicago however, we will pass on a contractor’s tip which you will only find here.  If you are looking for genuine deep dish Chicago pizza, there is only one place to go –Giordanos Pizzeria!  Fortunately, you are not limited to just one location, as there are 18 scattered around the city and even more in the suburbs.  The secret is for you, but just remember, you heard it here first!

 

Sample of Innovations To Be Seen at the AHR Expo

 

  • A digitally controlled mixing valve that provides precise temperature control for domestic hot water applications
  • A self contained HVAC system for hazardous locations, designed to prevent an explosion
  • New bionic impeller technology with a special blade designed to ensure optimized airflow angles and reduced flow separation
  • An oscilloscope for testing motor shaft voltages, allowing contractors to determine if motors are at risk of premature bearing failure

National Signing Day

Countering a Major Threat to the HVAC Industry

National Signing Day, or National Letter of Intent Day as it is known in some circles, is a noteworthy one.  Not only is it noteworthy for the student athlete, but it is also a big day for their parents, their coaches, and anyone else who has played a significant role in helping the student athlete with this achievement.  For those who may not be familiar with what this is, National Signing Day is the day when high school sports players publicly pledge their allegiance to specific universities.  What does this have to do with the HVAC industry?

 

I refer you to the ACH&R news article in the June 19 edition, written by Nick Kostora.  Nick’s article highlights the brainchild of Clark Coco, Dean of Washburn University Institute of Technology in Topeka, Kansas.  Clark was looking for an “out-of-the-box” way to get kids interested in the skilled trades that had not been tried before.  Now in its fourth year, National Technical Letter of Intent Signing Day is helping thousands of students achieve their moments of glory in more than 40 schools across the country.  National Signing Day events have been held at schools in Arizona, Kansas, North Carolina, Oregon, Tennessee, Wisconsin, Florida, Alabama, Minnesota, and Oklahoma.

 

National Signing Day had a remarkable impact on Washburn.  According to Coco, “When I got here, we were referred to as a tired and outdated facility.  We didn’t wear uniforms, we weren’t associated with NC3, (National Coalition of Certification Centers) there were weeds in the sidewalks etc.  Luckily, people really bought into what we were doing.  The school has seen 45% growth in enrollment over the past five years.”

 

Numerous articles have been, and continue to be written about the need for new talent coming into the industry.  This seems to represent an idea that you can latch onto in your local community.  Local ACCA chapters could set this up with local high schools and trade schools for example.  It is often said the HVAC industry is not very glamorous, but this is certainly an idea that can help it seem more so in the eyes of a young person.  It can help elevate the idea of going into the trades as a realistic alternative to college.  The shortage of skilled workers could very well become the biggest impediment to growth for companies in the HVAC industry in the very near future.  A recent article in BISNOW stated that 74% of construction companies in Texas say they are having a hard time hiring carpenters, electricians or plumbers.  Not only that, the HVAC industry is aging far more than other industries, meaning the average age of HVAC trade workers is older than the national average for other industries.  Ideas like this could very well represent part of the solution to this growing threat.

Could Energy Star Be Eliminated?

Could Energy Star Be Eliminated?Unless you have been living under a rock, you have almost surely heard of a program called Energy Star.  A recent industry publication cited a statistic that as of 2016, 91% of US households recognize the Energy Star label.  Beyond mere recognition however, what is Energy Star and how does it work?  Energy Star is a program established by the EPA in 1992, and it sets energy efficiency standards for appliances, electronics, houses and buildings.  It’s not a regulation however, as businesses decide on their own whether or not to design products that comply with the standards.  So, what’s my point?  Early reports indicate that the 2018 budget of the Trump administration may reduce the EPA’s budget by 31%, eliminating nearly 4000 jobs.  One of the programs rumored to be cut as part of this reduction is the Energy Star program.  Is that a good idea?

 

There is much agreement that the rate and volume of rule promulgation by the EPA in recent years has added cost and questionable benefit for consumers as regards the development of HVAC equipment.  Energy Star is different however.  Instead of compelling business to adopt specific energy efficiency standards, it seeks to encourage by promising recognition and consumer support.  The theory is that consumers seeking to purchase energy efficient products will rely on labels such as Energy Star to help guide their choices.  According to Energy Star, the program has been extremely successful.  They report that since its inception, Energy Star has helped families and businesses save $362 billion on utility bills while reducing greenhouse gas emissions by 2.4 billion metric tons.  In addition, about 1.8 million Energy Star certified new homes have been built.  What do HVAC companies have to say about all this?

 

Two HVAC contractors recently interviewed by the ACH & R News didn’t believe that their businesses would be hurt much if the program was to go away.  On the other hand, one felt its disappearance would negatively impact the HVACR industry.  Steve Lauten of Total Air and Heat in Plano said, “It gives incentives to provide air-conditioning systems that deliver installed efficiencies versus rated efficiencies… particularly in residential and new home construction.  Energy Star means the duct system is sized and sealed like it should be and it means that equipment is checked out and charged like it should be.  Energy Star provides some level of confidence for consumers and ensures they are making good decisions.”  Conversations with contractors in the article seemed to imply that the more your company talks to the consumer in terms of total building efficiency and installed versus rated efficiency, the less they might be impacted by the elimination of this program.  For the tens of thousands of contractors however who sell on the basis of rated efficiency and labels like Energy Star, the programs elimination could prove harmful.  What about manufacturers?  According to the article, a recent Associated Press report stated that more than 1000 US companies, including United Technologies and Ingersoll-Rand have urged government officials to preserve the program, stating it should be strengthened, not weakened, to encourage energy conservation.  One of the contractors in the article summed up his feelings this way.  “Cutting out something like Energy Star simply to save money is not doing the right thing for the country.”

Individualized Comfort

Have you ever walked into an office building and seen electric heaters on the floor by people’s desks?  Even worse, have you walked by an office and noticed cloth or cardboard stuffed into the diffuser?  That’s a clear indication of comfort problems.  A person is thermally comfortable when their bodies heat loss equals their heat production.  People vary, so what is comfortable for one individual is not for another.  What’s the solution?  Oftentimes a contractor will recommend installing airflow dampers in or rerouting ductwork.  More times than not, this results in an unsatisfactory solution.  How else can you correct the problem?  One way is with a VAV diffuser.

 

Individualized Comfort

Titus model T3SQ shown above, providing a view “above the ceiling.” The black device is the wax filled actuator. When the wax heats up, it causes the arms to rise, thereby listing the damper and allowing more airflow. When it cools down, the arms relax thereby lowering the damper. The minimum airflow adjustment ring can be seen in the center of the actuator, and the heating and cooling setpoint adjustment rings are found in the top half of the actuator.

 

What is that you ask?  Simply put, a VAV (variable air volume) diffuser is one which modifies airflow to the space based on a thermostat controlled by the user.  In other words, in a space heated and cooled by a rooftop unit, individual offices or spaces can have their own diffuser and their own thermostat.  If more than one third of the load is controlled by these diffusers however, a dump zone must be maintained in order to avoid damage to the compressor.  So for example, on a 5 ton unit, (2000 CFM) a dump zone must be maintained if more than 600 CFM is being controlled by VAV diffusers.  How do they work?

 

Using an architectural Square plaque ceiling diffuser, manufacturers incorporate a wax filled thermal element attached to the top side of the plaque.  (See picture) There are no wires involved.  This thermal element gets its room air temperature reading via a sensor mounted in the center of the diffuser.  The sensor allows for no more than a 1°F dead band between the induced room air temperature measured by the sensor and that of the zone air being supplied to the diffuser.  If the space begins to heat up in the cooling mode, wax in the thermal element also begins to heat up, thereby raising up the damper in the diffuser and allowing more airflow into the space.  As the room sensor become satisfied, the wax in the thermal element begins to cool down and the actuator assembly lowers, thereby reducing airflow to the space.  At least one manufacturers design allows the user to adjust the minimum airflow of a satisfied diffuser anywhere between 0-30%.  This capability allows the control necessary to meet Ashrae Standard 62.  Furthermore, these diffusers are listed by AHRI, so their rated performance has been tested by a certified lab.

 

What does this mean for the astute contractor?  Simply put, opportunity!  Consider the following statistics.

  • Thermal comfort is the most often cited complaint in office buildings today
  • Studies have linked improved comfort to reduced absenteeism, and thereby improved productivity
    • Labor costs are typically 10 times that of a property, so an improvement in comfort is rewarded with large returns in productivity

 

In a commercial building setting, awareness of the technologies that have a measurable impact on personal comfort and therefore productivity can help your company become the contractor of choice for problematic applications.

Those Dirty Grilles – Part 2

In the previous article, we talked about terminology and the difference between a diffuser, a grille and a register.  In this article, we are going to talk about dirt streaks on the ceiling, their causes and solutions.

 

The Titus TMS diffuser – the world’s 1st anti-smudge diffuser! Invented by Titus in 1955 to accommodate the trend toward acoustical lay in ceilings needing a square diffuser with a radial air pattern.

 

We have all seen restaurants or office buildings where the ceiling has become smudged and dingy with dirt streaks running across the ceiling next clearly coming from the air outlet device.  Most people assume the cause is dirty filters or dirty air within the space.  While they are contributing factors, there are several others which most contractors will not think about.  Fixing this problem when other contractors have not been able to could bring you a long-term customer!  So what are those other factors?

 

The first thing to look at are the air outlets (assume they are diffusers) themselves.  Have they been properly chosen for the application?  Believe it or not, diffusers are more than just “hole covers.”  Perhaps future articles will tackle the discussion of air inlets/outlets and their general applications, because the scope of this discussion is beyond this article.  You would be well served however as a contractor to take an application class from a trusted industry source such Hart & Cooley or Titus.  Bear in mind, proper diffuser selection cannot only impact dirt streaks but also sound levels within the space.

 

The second thing to keep in mind is the duct system leading to the diffuser.  Are the duct air velocities appropriate or is there a restriction somewhere?  It is not uncommon for example to find a situation where the round duct is kinked as it enters the top of the diffuser.  If there are restrictions, outlet velocities will be much lower than they should be, causing induction with room air as soon as it leaves the diffuser.  If you find this to be the case, there are companies that offer a brace designed to shape flexible ducts into highly efficient 90° elbows at the diffuser inlet.  When room air mixes with supply air at the outlet of a diffuser, not only will the system perform inadequately but you could also smudge the ceiling.

 

The third thing to keep in mind are the jet characteristics in the four zones of expansion for a diffuser.  As air leaves an outlet device, four distinct zones of expansion define the jet of air.  Jet velocities from a ceiling diffuser can be measured outward from the discharge point of the device.  The first zone which is closest to the outlet of the diffuser extends approximately 1 ½ duct diameters from the face of the diffuser, and is characterized by a constant velocity with minimal mixing of supply and room air.  In other words, a properly designed air distribution system will not induce room air within 1 ½ duct diameters.  For example, if the diffuser is being fed by a 7 inch round duct, there should be no room air mixing with the supply air within the first 10-12 inches.  In the second zone, the jet of air begins to mix with room air, and the resultant induction causes the jet of air to expand.  Velocities may well exceed 150 ft./m in this zone, depending on the design and application.  The third zone is where most of the induction occurs, and is the most important zone because it has the most effect on room air velocities and room induction.  Velocities at the edge of this zone may run between 50 ft./m(considered terminal velocity) and 100 ft./m.  The fourth zone is the one with relatively low air velocities.  Typically, air will reach terminal velocity in this zone.

 

Understanding the science and principles of air distribution can be a point of marketable differentiation between you and your competitors!

Those Dirty Grilles

A grill + a damper = a register!

My pastor writes a weekly blog, and recently he mentioned a life experience where he was completing the wiring of a new Nest thermostat as part of a DYI project to make his home more energy efficient.  He said he was feeling self-assured as he connected the power wire to the thermostat from “the heater,” but later that night awoke to a cold house.  While I found it interesting how he made the connection between an HVAC project and the Almighty, that is not the subject of this blog.  I did find a part of it worth discussing however, and that is the topic of terminology.

I responded to my pastor that it was a great article, but that as a member of the HVAC community, I had to let him know that from a terminology perspective, the wire was actually coming from his furnace, not the heater.  Similarly, have you ever had someone walk into a room, look up at the ceiling and say something like, “Wow, those grills are really dirty.  They need to change them.”  That statement is just wrong on many levels.

 

Let’s first address the term “grilles.”  A grill is something you cook on and a grille is an air outlet or inlet device.  You would not want to cook on a grille, as it would leave funny looking sear (not to be confused with seer) marks and likely impart the taste of cooked paint to your food.  While we are on the topic of grilles, let’s clarify once and for all what the differences are are between air inlet and outlet devices.  (ASHRAE’s term)  Grilles can be used on both the supply and return air side of the system, and are technically described as a device whereby the inlet and outlet area, size and shape are generally the same.  In general, a grille is also a device where the general direction of the air coming from the ductwork is not changed after passing through the grille.  Adding a damper to a supply air grille makes it a register.

 

A diffuser is a supply air (only) device that is used to achieve specific objectives related to airflow patterns and mixing.  More specifically, a diffuser is an air outlet device in which the inlet and outlet area size and shape are generally not equal.  In addition, the direction of air leaving a diffuser usually changes from the direction in which it is traveling when it leaves the ductwork.

 

Whew, I’m glad we cleared all that up.  What about the comment related to dirty grilles and the need to change them?  Read next week’s blog and we will tackle that statement.  Meanwhile, I need to go check the setting on that automatic ambient air setpoint control device!

The HVAC Gateway Drug

Typical Sources of Air Leaks in the Home

Typical Sources of Air Leaks in the Home

A gateway drug is one that is habit-forming, and while not addictive in and of itself, it may lead to the use of other addictive drugs.  For example, many have maintained that marijuana is a gateway drug leading to other illicit and more harmful substances.  For HVAC contractors, could adding insulation be a gateway drug toward full involvement in home performance contracting?

 

Adding insulation is one of the most beneficial things you can do to make a home more energy efficient.  Take a look at a Manual J calculation from one of your recent retrofit jobs.  (You do run load calculations on your homes, don’t you?)  Run some simple calculations to see what the addition of insulation would do for the homes total heat loss/gain?  This additional service in your company could provide an ideal way to increase your labor productivity, (billed versus paid hours) or to increase capacity by adding new people to perform this function.  Before making this plunge however, you need to do your homework.

 

The first thing to realize is that you are not just getting into the insulation business, you are getting into the business of making the home perform better.  That means finding and sealing leaks in addition to insulating.  Sealing air leaks means stopping air that comes through your homes envelope – outer walls, windows, doors and other openings.  This will lessen the pollen, dust and insects entering the home, while reducing outside noise and providing better humidity control.  According to Energy Star, most homes in the US do not have enough insulation and have significant air leaks.  They maintain that a typical home has leaks that average the equivalent of having a window open every day of the year!  When your customers understand this, they are incentivized to do something about it.

 

You also have to prepare the employees within your company for this new capability.  Sales staff need to be trained on how to offer insulation and air sealing, while getting their buy-in to do so.  Simply mandating that they attend training and start offering these new services will not get the job done.  Once they understand the benefits to both their customers and themselves however, they will be more inclined to seek out these opportunities on every sales call.

 

Similarly, your technicians need to be trained on the proper techniques and tools to be used when sealing and insulating a home.  Organizations such as Everblue offer a BPI Weatherization Certification Course where students can learn in a certified environment.  Learning about the types of insulation to be used in a given application will depend on each homes individual needs and climate/location.  Finally, your scheduling staff must be trained on what is required in order to properly stage insulation/air sealing with equipment installation.

 

By successfully adding this capability to your business, you will have opened the door toward becoming a true home performance contractor, as opposed to a company that merely installs heating and air conditioning equipment.
