Emissions reporting: A starting point for carbon and sustainability opportunities
As discussed in the May/June 2024 issue of Mechanical Business, reporting structures and frameworks for businesses are now finalized to allow consistent measuring and tracking of emissions and are being integrated into a business’s financial reporting. This provides parties interested in supporting the financing or purchasing of a business with a standardized, consistent way to evaluate and compare businesses’ climate related data. They can also see the climate risks/opportunities for the business and actions taken, including costs.
Customers can assess a match to their own climate related specifications, emissions targets, expectations and any advantages they receive through transactions with your business. Your customers may be able to utilize these plus your business’s reductions to contribute to their own GHG assessments and emissions reporting.
Accurate emissions reporting is the first step. This is the same as “measuring and stating” values for any other functional area of your business. For example, when you complete your business’s financial statements for a given period, you review and look for areas to improve and the costs; you evaluate market changes and trends that may impact your business and take action. The “standardized” nature of financial reporting means others can review your statements, assist your review, make their own evaluation of your business to support you or choose to purchase from you.
Emissions reporting is similar. The emissions reporting structure for Canada is the ISSB IFRS S1, S2 and includes the Scope 1, 2, 3 Framework. Companies need to identify their gaps in providing the required data, determine if this data is/can be collected and how this is done. What data are you providing customers? What data are you receiving from suppliers? What data are you requesting? Once consistent data and measuring is established, then targets or goals (percentage reductions) can be determined, actions taken and tracked.
A final comment. The term “emissions reporting” is being used selectively in other contexts, where it may represent only a component part of some business’s total emissions. For example, building owners in major cities in Canada and in North America are having to comply with city’s/municipality’s reporting mandates on each building’s energy and water use and the associated emissions. This is only a component part of that building owner’s total emissions. Recognize the opportunity for your business − that building owners could be interested in lowering their emissions by making changes to the mechanicals in their own buildings.

Atlantic Ministers concerned about the impacts of Federal Workforce Funding cuts
Atlantic Workforce
Ministers met on June 6, 2024 to discuss the impact of the $625 million cut to Labour Market Transfer Agreements (LMTAs) on workers and employers announced in the April 16, 2024 budget. They are demanding the federal government reverse the cut. With this cut, LMTA funding will revert to pre-2017 levels. Coming mostly from the Employment Insurance account, this decision means a $62.3 million annual reduction in funding for skills training and employment initiatives in Atlantic Canada.

Ontario legislation eliminates NOSIs
On Monday May 27, 2024, the Ontario government introduced new legislation that removes the ability to place Notices of Security Interest (NOSIs) for consumer goods in the land registry process. The legislation received Royal Assent on June 6. NOSIs were originally used by companies who leased or rented household goods such as HVAC equipment and appliances for a home to “protect themselves when such appliances were purchased with financing,” according to the government. Entitled “the Homeowner Protection Act (HPA), ” this legislation will eliminate new NOSIs as well as all NOSIs currently in place. Look for more information at mechanicalbusiness.com (search NOSI).

REFRIGERANTS
Clearing up confusion
What is the difference between OEM and retrofit requirements?
There appears to be some confusion in the Canadian refrigeration and air conditioning (A/C) industry particularly in the contractor community, concerning the current federal refrigerant regulations. In 2016, the federal government adopted the Ozone-depleting Substances and Halocarbon Alternatives Regulations (ODSHAR) under the Canadian Environmental Act. This was the next step in reducing the use of HFCs and moving the industry towards lower global warming potential (GWP) refrigerants.
Canada’s ODSHAR is consistent with the international Paris Accords on Climate Change; reduce the use of HFCs in refrigerants and move to refrigerants that have less effect on global climate. Many HVAC/R contractors do not fully understand what these regulations apply to and how they are going to change their business.
“The feedback from our customers tells us contractors in general aren’t aware that the current ODSHAR only applies to new OEM equipment being manufactured in or imported into Canada,” said Jim Thomas of Refrigerant Services Inc. in Dartmouth, NS. “The ODSHAR does not apply to existing installed equipment.” He went on to say the federal government’s jurisdiction only covers the import and manufacturing of regulated refrigerants and products that use these refrigerants. There are no HFC refrigerants produced in Canada.
The issue of regulating installed refrigerant containing equipment is provincial jurisdiction. “Currently in Canada, there are no provincial regulations that restrict the use of HFC refrigerants with existing equipment,” said Thomas.
THE CANADIAN ODSHAR
The federal ODSHAR is the first step in reducing maximum GWP levels for HFC refrigerants used in new refrigeration and air conditioning products. This initial step involved refrigeration equipment, including stand-alone low and medium temperature systems, centralized systems, condensing units, chillers and mobile refrigeration.
As of January 1, 2020, new refrigeration systems covered by the ODSHAR were prohibited from being imported into or manufactured in Canada if they operate using a refrigerant with a GWP at or above 1,400 or 1,500 for stand-alone systems and 2,200 for central systems and condensing units. On January 1, 2025, new stand-alone residential systems such as refrigerators and freezers are restricted to a GWP of 150, chillers are restricted to 750 and mobile is restricted to 2,200.
GWP was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emission of 1 ton of a gas will absorb over a given period of time, relative to the emission of 1 ton of carbon dioxide (CO2). GWP levels of some common HFCs include HFC-404A (3,922) and HFC-507 (3,985). Some of the new lower GWP HFC refrigerants are HFC-448A (1,386) and HFC-449A (1,397).
With the exception of chillers, ODSHAR does not contain restrictions on unitary air conditioning such as residential splits, commercial and industrial rooftops. When the ODSHAR stakeholder consultations were conducted prior to 2016, the manufacturers of these products requested more time before including unitary A/C to see how regulations in the U.S. and other countries were sorted out. Canada’s market for unitary products is too small to move out of step with other countries. A good example is the recent U.S. Environmental Protection Agency (EPA) rule on HFC Restrictions and Technology Transition. This rule requires GWP levels for refrigerants used in new stationary residential and light commercial air conditioning and heat pumps be at 700 or less starting on January 1, 2025.
“With the U.S. and other jurisdictions moving to or already having stringent A/C requirements, the federal government appears to view these requirements as an international standard that will benefit Canada without necessarily having to include A/C in the ODSHAR,” said Thomas. The industry should also be aware that the U.S. rule making

requirements for refrigeration and chiller equipment is also close to the GWP limits included in the ODSHAR.
REFRIGERANT ALLOWANCES
Similar to CFCs and HCFCs, the ODSHAR includes permitted consumption allowances for importation of HFC refrigerants. Companies that qualify for HFC importation have a base consumption allowance that will gradually be reduced every five years starting in 2019 and continuing to 2034.
On January 1, 2019, the base consumption allowance was reduced to 90 per cent and on January 1, 2024, it was reduced to 60 per cent. In 2029 and 2034, the allowance will decrease to 30 per cent and 20 per cent respectively. In 2036, the final reduction in the allowance will occur with the consumption allowance dropping to 15 per cent. These requirements only apply to importation of bulk refrigerants and does not apply to refrigerant contained in imported precharged units.
HOW WE GOT HERE
SUMMING UP
What contractors should know about the federal ODSHAR is:
1. They only apply to NEW refrigeration equipment either manufactured in or imported into Canada.
2. They do not apply to existing installed refrigeration equipment; only provinces can regulate existing equipment.
3. There are currently no provincial regulations restricting the use of HFC refrigerants in existing equipment.
4. They currently do not contain any restrictions on air conditioning equipment other than chillers.
Although HFCs do not deplete the ozone layer, they are often used as replacement for ODS and are powerful GHGs with a potent global warming potential.
Refrigerant regulations in Canada have been evolving since the first regulations were introduced in the late 1980s. These initial regs applied to CFC refrigerants and CFC using products because of ozone depletion. Many changes have occurred since those initial regulations were introduced including phaseouts of CFCs, HCFCs and products using these refrigerants, as well as a phase down of HFCs.
Many of the initially introduced HFCs that were supposedly a better environmental alternative, actually had high GWP. The international plan is to move equipment manufacturers and eventually the existing stock of refrigeration and air conditioning equipment to lower GWP refrigerant alternatives.
Contractors should also be aware there are other federal regulations that apply to refrigeration and air conditioning equipment under federal jurisdiction, such as federally-owned buildings. If you are doing business with the federal government, you must be familiar with the applicable regulations.
A word to the wise:
The amount of HFCs allowed to be imported into Canada is going to decrease dramatically over the next 10 years as will high GWP HFC equipment. Start looking at low GWP equipment and refrigerants that are being offered and gradually move your customer base in the right environmental direction.

High-tech all the way Fred Bretzke:
“I love sports. I love mountains, and I love teaching and designing 3D,” says Fred Bretzke, an instructor at Southern Alberta Institute of Technology (SAIT) and a long-time plumbing columnist for Mechanical Business. Winning SAIT’s 2024 Cadmus Teaching Chair, which includes time off and a financial award, has freed him up to pursue all of those activities.
The award is designed to foster faculty excellence in skilled trades teaching and allows instructors to develop a project, idea or concept to enhance trades education. Bretzke’s project is a SAIT Supplement that will redefine the 2020 National Plumbing Code Appendix into a 3D QR Appendix.
FUN FACT:
With powerful, long hind legs, mountain lions can jump 15 to 18 ft. vertically and 30 to 45 ft. horizontally.
Bretzke has always been committed to engaging students and to bringing clarity to the learning process. He was the 2020-2021 Innovation of The Year Award Winner: SAIT for digitizing the project-based learning approach that apprenticeship training is known for. “I went to a conference where they said you can understand 3D video 60,000 times faster than reading text. That is key in our education system now because they are cramming curriculum down students’ throats, which is not healthy − too much information and not enough time. So, the 3D helps them understand quicker,” says Bretzke.
“I’ve never met one grumpy person in the mountains ever in the last 12 years.
FINDING A BALANCE
Bretzke, who is diabetic, works to find a balance between his interests and relaxing but it isn’t always easy. “Ever since I came up with this monumental task of rewriting the code books, I get addicted to designing things − I can’t stop. Which is not a good thing. My doctor tells me I have to balance things out. You know, walk, hike and do a little bit of 3D. It’s amazing. When you’re creative, the mind gets going. But I think the trick to a happy life is to balance things out. I’m still learning it.”
There are some time constraints with the project, which was to run from September to January. “I asked for a jumpstart. I was able to buy all the latest technology for this project. I’m off in summer, so on blue sky days I will be hiking and on rainy or crappy days, I will be working on my Cadmus project. This way I don’t have to rush at all in the fall,” says Bretzke.
THE TEACHING BUG
Bretzke spent two years serving a teaching mission in France where he learned Parisian French. That teaching experience, in addition to having plumbing and gas licences, would later land him his first job at SAIT. He worked in the field and in management at A&B Plumbing on two separate occasions but eventually returned to teaching in 2004. “It was valuable experience at A&B Plumbing, but my love has always been for teaching. Once you have it in your blood you can’t get rid of it. It’s not as lucrative and it may sound cheesy, but I think I’ve taught 4,000 or 5,000 plumbers by now. It’s great when you meet someone 20 years later and they actually remember you and say what a difference you made in their life.”
REACHING FOR THE TOP
That thirst for knowledge and love of technology are embedded in all aspects of his life. Hiking and climbing are passions for Bretzke but for many years physical activity was curtailed. After 10 unsuccessful surgeries, a knee replacement in 2012 stuck and he was off to the mountains. “I’ve hiked around 250 mountains since I had my knees replaced,” says Bretzke. “Now I have titanium knees and now my legs are like I’m 20 years old. I’m doing all the things my surgeons said I couldn’t do. It’s awesome what technology can do for you.
“In the summer, if I do a long hike, it might be an eight- or 10-hour hike, then I’m going to do some ridge climbing and climb a 9,000 or 10,000 ft. mountain but I’m not one of those guys who likes to sleep in a tent overnight. I have nightmares of getting pulled out of my tent by a bear.”
With wildlife aplenty in the mountains, it is inevitable that Bretzke would run into the stuff of his nightmares, sometimes on the side of the road, sometimes under more scary circumstances. “I’m not a religious person, but I do pray for four things before I go hiking. One is blue sky days, meaning perfect weather because you don’t want to be on top of the mountain in bad weather. On blue sky days you feel like Superman, you feel liberated. I wish for health, meaning I don’t break an ankle on top of the mountain. And, I wish for no animals like bears or mountain lions.
“The only time I had a scary moment was a few years ago. I was chased off a mountain by a mountain lion or bobcat or cougar or whatever you want to call them. It was a huge peak I was climbing and I was the only one there. The parking lot was empty, which is another stupid thing. I went up in heavy snow and mine were the only footprints. When I was coming back on the last plateau, I noticed urine marks in my footprint tracks. I wondered what left them. Sure enough, I turned around and 40 ft. away was a cougar. I took my backpack off, turned it into a toboggan, and slid the last 300 ft. down the mountain and wiped out into some rocks,” recalls Bretzke.
“Since then, I carry bear bangers, which make noises, and I try to hike with someone. But I have done, probably foolishly, about 50 per cent of my mountains on my own, only because I enjoy going at my own pace.”
Bretzke likes to take selfies on top of mountains and ridges. His students have said “You’re probably gonna die falling off a cliff taking a selfie.” Since he’s into technology and values his student’s input he bought Ray-Ban Meta smart glasses. “They are probably going to save my life. It’s true, because I used to have a GoPro. Before that I just had my cell phone. I would have one hand on my pole or holding on to a mountain and then take pictures. With the smart glasses all I do is say Hey Meta, start recording. I can listen to music through the arms. I can get audio texts. And it takes great high-definition pictures and videos, which frees up my arms. I’m the modern, high-tech hiker.”
It puts you in a positive mood. It’s my reboot.”

Hydronic control valves Part III CONTROLS
Rick Mohammed, A.Sc.T., is a regional application consultant with Belimo. He can be reached at rick.mohammed@ca.belimo.com.
Balancing and the effects of low Delta T
InPart I of this series (Mechanical Business Sept/Oct 2023), we reviewed the different types of control valves found in hydronic systems. In Part II (Mechanical Business March/April 2024) we learned how to size and select a control valve. In Part III, the final edition, we discuss the challenges with balancing many control valves on a hydronic loop, and the drastic effects an unbalanced system has on system performance and energy consumption. In almost all hydronic systems the flow of water is unevenly distributed throughout the piping system. In some areas closer to the pumps there will be higher pressure and too much flow, and in other areas farthest away from the pumps there will be lower pressure and too little flow. We see this often in buildings when we ask operators about their pumps. Often, we are told the pumps are running at high speed, and they have to manually turn the speed down when loads are low.
FIGURE 1
DELTA T (ΔT) is the difference in water temperature entering and leaving a coil, heat exchanger, or supply and return lines to the plant.
There is a relationship between pressure, flow, and Delta T (ΔT). A low ΔT below the original design at the AHU and at the cooling or heating plant, is a big indicator a system is using too much energy and not delivering its maximum load.
The process of balancing flow in a hydronic system includes opening all the valves in the loop, increasing the pump to full speed, and adjusting a balancing valve to get the maximum design flow for the coil in an AHU, FCU, reheat coil, or perimeter rad. We can see right away that the system is only balanced at full load and since all HVAC systems are oversized, it will operate below the maximum flow setting 99 per cent of the time. In other words, the system is unbalanced 99 per cent of the time.
Figure 1 shows a coil with a balancing valve set to 100 GPM. As soon as the modulating valve is below 100 per cent open the balancing valve is no longer offering balancing. This allows for excess flow to pass when demand is at part load and pressure is high.
As flow passes through a coil of an AHU too quickly, the heat transfer between the water and the air is not maximized. This is apparent in the measurement of the ΔT. Figure 2 shows the relationship between flow and ΔT. The red points create a power or heat transfer curve of the coil, and the blue points represent the ΔT of the coil. We can see the difference between 65 GPM and 55 GPM on the X axis correlates to a 5 KBTU/hr change in coil power. That is a 15 per cent change in flow to get only a one per cent change in coil power. We also can see that the difference in ΔT shown on the right-hand axis increases from 10⁰F to 12⁰F as the flow drops to 55 GPM. That means 65 GPM of flow is too high which leads to a lower ΔT, and very little change in coil power.
When ΔT is low at the various coils or heat transfer devices, the temperature of the water returning to the chiller or heating plant is not at design. This limits the load the chiller or boiler was designed to generate. The result is an overworked system, high energy consumption, and compromised occupant comfort.
In Figure 3 we have a chiller rated at 200 tons. The chiller generates 42⁰F water that is sent to the AHU cooling coil and it needs a 54⁰F return water temperature for a 12⁰F ΔT. When the flow through the coil is too high the heat exchange between the water and air is reduced. This is shown in the delta measurement at the supply and return of the coil. It also causes the return water temperature to be colder at 48⁰F. The chiller is now getting a six-degree ΔT and its capacity drops from 200 tons to 100 tons.
By eliminating the overflow at each AHU we can achieve equal distribution of flow throughout the hydronic loop, and correct the underflow in other areas at the same time. This will in effect correct the ΔT at each coil. But what does that mean for the plant?
Let’s look at a typical primary/variable secondary loop system. Figure 4 (page 30) shows a system with 3 chillers each rated at 200 tons on the primary side. Each chiller has a dedicated constant flow pump. On the secondary side there is a secondary pump with a variable frequency drive that is driven by a differential pressure sensor installed after the last air handling unit, AHU 3. Each AHU has a standard two-way valve and a balancing valve to vary the flow as the load changes in the space being cooled.
Let’s recall the limits with balancing flow mentioned earlier. The pressure and flow through each AHU is unbalanced. This causes overflow through some cooling coils of the AHU, and underflow through others. As the flow of water passes through the coils too quickly it does not pick up enough heat from the air. This reduces the ΔT between the supply water and return water temperatures, and it also decreases the return water temperature going back to the chiller plant.
Just like in the earlier chiller example, the chillers are selected to provide a supply water temperature of 42⁰F and they require a return of 54⁰F to give a 12⁰F ΔT for the chiller. A 12⁰F ΔT allows the chiller to operate efficiently and deliver 200 tons of cooling. AHU 1, AHU 2, and AHU 3 have return water temperatures of 45⁰F, 46⁰F, and 52⁰F. When these temperatures are mixed in the return line going back to the chiller plant, we can see a resulting return water temperature of 48⁰F. The ΔT at the chiller plant is now only 6⁰F causing the chiller to deliver only 100 tons of cooling. As the load of the building increases, chiller 2 must come on earlier to make up for the lost chiller capacity.
Many building operators tell us they have to add a chiller because they cannot cool the building when outside temperatures are high. Usually, we find the ΔT at the plant is significantly below the design ΔT.
FIGURE 3
To fix the balancing, over pumping, and low ΔT problem we can apply the use of smart valves as shown in Figure 5. The standard two-way valve is replaced by a smart valve and the traditional balancing valve can be removed or simply fully opened. The smart valve can be set up with a position, flow, or coil power set point depending on the system. It can also be set up with a ΔT setpoint. This way flow and ΔT can be customized for the AHU which will then correct the return water temperature, and improve chiller operation. The same concept can be applied to a heating plant where condensing boilers are not condensing and causing excessive gas consumption.
Control valves used in the HVAC industry have evolved into more than just a mechanical device. They can include a flow meter, temperature sensors, BACnet communication to collect useful data such as energy use, and built in algorithms to manage flow accuracy, ΔT, and power output.
Smart valves can dynamically balance a hydronic loop, improve system performance, and save considerable energy. This concludes the three-part series on control valves. We hope it has given you a new appreciation for control valves, and how control valve technology has evolved.
A smart valve is a component that can automatically adjust its position or flow rate. It uses data from sensors or a programmed control system. Sensors in smart valves can detect changes in temperature, water pressure, and flow. This can be used by technicians to adust balancing operations.

HYDRONICS
Fluidity fixes: How to properly drain a system
In my working definition, hydronics indicates the system will be based on a fluid to transfer the energy. As such, commonly seen systems that could be considered hydronic are radiators, fin tube, air coils, radiant, solar thermal, GEO loops, and A2WHP. I’d put steam systems in the hydronic category also.
There may come a time when one of these hydronic systems needs to be drained. It could be for a service call to fix a leak, or to replace a component, for example. It could be the system just needs to be flushed, cleaned and refilled from years of service. Water quality and the maintenance of the fluid has a lot to do with the need to drain occasionally. Non-barrier pex tubing used in hydronics is another example of a system that will need to be drained and serviced at some point. I have never witnessed crystal clear hydronic fluid, but dark coloured sludge in any hydronic system indicates a problem worth investigating.
If a component fails or ages out, the system needs to be drained.
In some cases, a drain down is a super simple task. A boiler or solar tank below all the piping would just need a valve at the low point to accomplish a drain down. Many of the cast iron boilers come equipped with boiler drains at the bottom. So, connect a short hose and open the drain and an air vent to get a good quick drain.
Personally, I prefer a ball valve to a compression type boiler drain to ease draining and flushing. Consider this upgrade on a new or repair installation. A handful of hose caps on your service vehicles can be helpful also. Eventually you will come across a valve that will not seal off. If it has a hose connection, a cap and washer is a quick, maybe temporary, fix.

Bob Hot Rod Rohr has been a plumbing, radiant heat and solar contractor and installer for 30+ years. A long-time columnist, he is involved with training and education at Caleffi North America. You can reach him at bob.rohr@caleffi.com.
In addition to a good wide open flow path for draining, a ball valve is best when pumping fluids back into the system. This will be handy if you want to pump in cleaners, conditioners, and possibly glycol for freeze protection.
When you pump backwards through a typical washer type boiler drain, you run the risk of pushing the washer off the bib screw. This will make it hard to seal off that valve. A typical compression type bib washer valve is intended for flow in one direction. There are plenty of options for ball valves with a garden hose connection. This is always a nice upgrade for a drain valve on a system. It offers higher flow rate and bi-directional flow options.
Systems with the components or piping below the boiler will be more of a challenge to drain. For a complete 100 per cent drain down of a system like this you pretty much need some compressed air. Compressed air with adequate volume will help push all the water out.
Come to the job prepared with several drain/purge tool options.
Fin tube circuits blow out fairly easily. Thousands of feet of pex tubing in a slab, for example, will take more time and patience to completely drain. Ideally a manifold with isolation valves will allow you to blow out one or two loops at a time.
On small residential systems, a wet vac can do a good job of getting all the water or fluid out. A wet vac is also handy for cleaning up spills of the work area after you complete the job. There are a number of good cordless vacs available if you roll without power corded tools these days.
It’s not a bad idea to purge the system fluids out into buckets or a plastic barrel to get a good idea of the system’s capacity. With a total water content measurement, you make easy work of adding glycol, cleaners, or inhibitors. I like to see what flushes out, too. Flushing out solder balls, Teflon tape shards, copper reams, etc. tells a lot about the previous installer or service contractor skillset. And, the more shrapnel in the system, the more potential damage you might uncover.
Old glycol or other unknown fluid blends should go to a recycler. Check your city or town website for recycling options.
A fill cart with at least a ½ hp pump can also be handy for flushing and refilling as well as injecting chemicals or glycols. On larger, more piping-intense systems, you may need to cut in some isolation or drain valves to speed or complete the drain down project. Break the system into manageable circuits.
Press-type valves and tees are great for cutting into systems. I believe there are press systems for copper, stainless, and schedule 40 piping now available. You can also use grip type valves and fittings, if you are comfortable with that type of connection.
If you are a tool buff, a pipe freeze kit can be a job, or reputation, saver.
Some valves come with dual purge ports and a ball valve in between.
These can be handy for flushing two directions.
It is worth spending a few dollars more to get a quality valve. The low-priced, lowquality valves tend to have small diameter stems, thinner forgings, and no packing nut. They look and feel cheap. You want the valve to last more than one cycle.
When you do add valves, think about how they can be installed to serve multiple functions. As an example, consider pump isolation flanges. These can function to isolate and replace or repair a pump, and to purge or drain those points in the system.
In a perfect world, a valve would be exercised from time to time. Left untouched for years, valves can stick in the open or

closed position. “Forcing” them to operate can result in a broken stem. Or worst case, a valve that moved partially through its stroke, and then the stem broke. If you spend years in the field, you will come across many of these issues, so be prepared.
The combination of a freeze kit and a press valve or fitting can certainly turn a problem job into a quick simple win for a service technician. This repair can also be a unique money maker.
That’s just my short list of fluidity fixes – if you have a tip or trick, let me know and I can share it in future columns and podcasts.

Transforming a Century-Old Brand into a Market Leader
Celebrating 100 years, Milwaukee Tool, a subsidiary of Techtronic Industries Co. Ltd. (TTI), has been refined and transformed over its time. Innovation isn’t just a buzzword for the heavy-duty power tool manufacturer–it takes years of leadership and culture to get there.
Here’s how Craig Baxter, group president of TTI Canada, transformed Milwaukee tool in Canada to bring it to where it is today.
How do you transform a 100-year-old brand like Milwaukee Tool, taking it from the back of the pack in market share to the leading maker of professional power tools and equipment?
“You don’t do it by setting goals you know you can achieve,” says Craig Baxter, group president of TTI Canada. “Very little that’s great has ever been achieved by setting easily achievable goals. I’m a strong believer in audacious goals,” adds Baxter. “I love that word. An audacious goal changes everything. It changes the way you think, the way you plan, the way you behave. It changes your entire approach.”
Sixth in a Five-Horse Race
If anyone would know from experience about the power of audacious goal-setting, it’s Baxter. In 2007, when he first joined Milwaukee Tool, the company’s products were barely on the radar as a job site solution.
“We were sixth in a five-horse race in terms of the market share of professional cordless tools,” Baxter recalls. “My first audacious goal was committing back in 2007 to make Milwaukee the number one brand of professional power tools in Canada by 2017. To achieve that meant we had to grow at least 20 percent a year for 10 straight years.”
Under Baxter’s leadership, Milwaukee Tool didn’t just achieve that goal—they smashed it. “We’ve compounded at 24 percent for the last 16 years,” he shares.
Leading by Inspiration
But while Milwaukee Tool’s continuous innovation is critical, Baxter credits his workforce—and the incredible spirit of teamwork and collaboration he set out to foster—for these incredible results.
Having taken the company from less than 100 employees in 2007 to almost 800—“We have single-digit turnover,” Baxter notes—he’s determined to build the best possible team and the best possible work culture.
“My job is to create an environment where talented, ambitious people can flourish,” he says.
For Baxter, that all hinges upon leadership. “The predominant leadership style today is command and control,” he adds. “But that style is never going to lead to extraordinary results over the long term. And that’s because great people simply don’t want to be controlled.”
Baxter continues, “If you don’t understand how to get the best work out of individuals, then extraordinary results will be incredibly difficult to achieve,” he says.
Great leaders are able to inspire people to become the absolute best version of themselves, and in so doing, they’re able to stretch for audacious goals.

Ou r Ex t re m e Metal and Extreme Material options are the b es t -perf ormi ng c ut ti ng products on the market, and professionals need a blade that can stand up to the wide range of heavy-duty m aterials they face in a day” Baxter shares.
Speaking of battery systems, our new REDLITHIUM™ FORGE™ batteries are the most powerful, fastest charging, and longest life batteries within our cordless systems.
“ ”
With the MX FUEL™ REDLITHIUM™ FORGE™ XC8.0 and HD12.0 battery packs, we ensure our tools deliver peak performance and extended runtime, enabling professionals to tackle demanding tasks without interruption,” he notes.
Baxter acknowledges. “Our vision is a cordless job site—and by that I mean everything from a small renovation to building a tower downtown. Our vision is to have every single application on that job site powered with a lithium-ion solution brought to you by Milwaukee Tool. We want to replace other batteries, replace hydraulics, replace pneumatic air, replace gas and cords. Any source of power on the job, we want to replace it with one of our solutions. In five years, I see us providing solutions that are beyond anybody’s imagination on a job site,” Baxter shares.
With such a great team and strong leaders on his side, it’s yet another audacious goal Baxter believes is within reach. “Just look at what we’ve brought to market so far. You can only imagine how many solutions and the type of capabilities we will provide in the future. We are just getting started.”

Dallas Blatkewicz
Dallas Blatkewicz The multi-tasker ROAD WARRIOR
Situated about 145 km southwest of Edmonton, Drayton Valley, AB is known for its beautiful surrounding wilderness, as well as its booming oil fields. So it wasn’t surprising that Dallas Blatkewicz initially planned to work in the oil industry in instrumentation. But the industry is known for its boom and bust cycles, so when Blatkewicz graduated high school and was unable to find a job, his father Dale, owner of Bald Eagle Plumbing & Heating, suggested he come work for him.
“I just kind of fell into a job,” Blatkewicz recalls. “The job where I wanted to go, nobody was really hiring, but he needed workers so I helped them over the summer. And I promised him I would get my ticket for plumbing, and then I was going to go back to instrumentation.”
He found he enjoyed the work, and enrolled at NAIT, graduating as a journeyman plumber in 2015. Since then, he’s also taken on a refrigeration and air conditioning program, and is currently in his fourth year.
“We hired a few refrigeration guys, but they didn’t really stay long, and I got a taste for that so I said, I’ll just go to school and do it. Now I prefer the furnaces, the boilers, the heating and air conditioning side of my trade.” Blatkewicz is also the company’s installer for private sewage systems.
Servicing and repairs are the company’s bread and butter, with residential comprising about 80 per cent and commercial 20 per cent. Bald Eagle also does installations and renovations, particularly hydronic systems, something Blatkewicz also enjoys.
“They’re just a nicer system to work on. Pulling it apart, doing a little troubleshooting to make you think a little bit, that’s always fun. Pretty much all our apartment building [customers] have hydronic heating, and there’s a lot of homes with hydronic heating, or a combination

of both a furnace and hydronic heating, especially newer homes in the region,” he says. “Our winters are fairly cold, so it is nice to have a second source of heat if something breaks down so you’re not completely stranded in the cold.”
Blatkewicz and the team at Bald Eagle are currently rebuilding a customer’s hydronic system around an older boiler which will eventually be replaced. “We’re redoing all the piping and the boiler loops and everything, we do that fairly frequently. We’re pretty much cutting out his old system, leaving the old boiler in there for now and then redesigning it as we’re putting the new high-efficiency system in.
“The way we’re doing it is helping extend the life of his current boiler as secondary heating. When he needs to change that boiler, it will be a lot easier for him and a lot less expensive. I’m a big proponent of if we’re allowed to take apart everything, like we’re doing with this customer, we can redesign the whole system and keep the older boiler a lot of times. There’s newer technology in hydronic systems, new ways of doing stuff. So doing the install, doing the piping layout, there’s so much that can make your boiler work so much better, even an older boiler.”
Blatkewicz says educating new customers about the system can sometimes be a challenge. “If somebody moves to a home with hydronic heating, they don’t always understand it’s a different type of heat, it’s a slower reacting heat. Another big thing would be service – it needs to be checked, it needs to be looked at. I try to educate them on having somebody come out and take a look at it every year, servicing their equipment and not just letting it run until it finally breaks. So, catch the small stuff before it turns into a big problem and you’re freezing in the middle of winter.”

ENERGY EFFICIENCY
By Matthew Reid
Making the case for zoning
Whenwould it be advantageous to a homeowner to have one centralized system all controlled by one thermostat? After all, the occupied areas can and should be kept at a different temperature than the unoccupied areas in order to save energy. The reasons to support or design in a zoned type of system are incredibly easy to see and understand.
Consider a two-storey house. The main level will be the living room, kitchen, dining room, and a bathroom. The second storey will be all bedrooms. Let’s also say it’s winter and we are talking about heating. During the daytime, the main level (occupied) can be kept at a warmer temperature than the second storey bedrooms (unoccupied). The second storey can be allowed to cool slightly thus saving energy.
Now is as good of time as any to explain how temperature turndown/setback works and how it saves energy. For all those readers who say setback thermostats don’t work or end up costing more in energy to reheat the area after being set back, please keep reading.
DOING THE MATH
Let’s say we have a heat loss of 100,000 BTU/hr. Our design temperatures are going to be -20⁰F outdoor design temp (-29⁰C) and inside design temp is 70⁰F (21⁰C). Using the formula Q=AxUxΔT (Delta T), let’s break it down and then we can start filling in the numbers we know.
Q is the required quantity of BTUs to heat an area at design temperatures over the course of an hour.
office. He can be
house is unoccupied for most of the day, presenting an opportunity for energy savings through zoning.
ΔT (Delta T) the differential between the heated area versus the outdoors.
The Q = 100,000 (pulled out of thin air for easy math). The A for this scenario will be 22,222 sq. ft. of exterior wall. The first floor is identical to the second storey (again picked so the math would work) and the U will be an insulation value of 0.05 (R20). Delta T will be 70⁰F indoors versus -20⁰F outdoor so ΔT is 90.
Formula: 100,000 = 22,222 x .05 X 90
100,000 BTU/hr is the total heat loss, 22,222 is the total exterior envelope area, .05 is the U factor or insulation factor and ourΔT is 90. The thing to keep in mind is that this number is based around 60 minutes. We use 100,000 BTUs in one hour to keep this house at 70⁰F.
A is the surface area of exterior walls able to perform heat exchange when there is a temperature differential between indoors to outdoors.
U stands for the U factor. To calculate U, you must first know the R value of the insulation and then use the formula U=1/R. In some cases, such as windows, the U factor is given instead of R value.
What happens though if we create two zones; the main floor and the second floor. Let’s decrease the indoor temperature to 60⁰F in the second storey bedrooms but let’s only do it for one hour. We will have two calculations: second storey Q = 11,111 X .05 X 80 which equals 44,444 BTU/hr, and the main floor Q = 11,111 X .05 X 90 which is 50,000 BTU/hr for a grand total of 94,444. A saving of

5,556 BTUs worth of energy in an hour. The argument goes that you will lose the energy savings when you turn the temperature back up so let’s do that math and see if it’s true.
First, we have to turn the temperature back up. We are at 60⁰F and we want the temp at 70⁰F Delta T, therefore Delta T is 10⁰F. This is called the pickup load. Q = 11,111 X .05 X 10 or Q = ~5555 After that you must add back in the 50,000 BTU/hr to maintain that 70⁰F for the next hour making the total 55,555. We saved 5,556 BTU/hr by turning the thermostat back and used about the same to turn it back up. This is true, but what happens if we can set the temperature back for multiple hours?
Remember in this case we are zoning the unoccupied bedrooms of a house, which can be vacant for up to eight hours out of the day or more. Hopefully more to all the Nintendo diehards out there. It will always only cost you an additional 5,555 BTU/hr to bring this zone back up to temperature but you only need to do it once, so the longer you can leave it in setback, the more energy you can save. In one hour, we save 5,556 BTU/hr worth of energy. In two hours 11,112, over the course of a day or eight hours, we saved 44,448 BTU/hr worth of energy.
It’s only with quick temperature setbacks that the occupant may be losing or breaking even on energy consumption and even then, there were some variables that I didn’t include into the calculation to simplify the math. The long and the short of it is, your customer will save money and energy by turning down the temperature and the longer they can keep the number down for, the more energy they will save.
WHEN DO YOU WANT ZONING AND WHERE?
In theory, zone wherever the system will allow you to do so. The only issue would be if the system equipment can’t really handle zoning. For zoning to work properly, the heat output of the heat source (furnace or boiler) should be able to mimic, match or buffer the zone load.
If you have a 100,000 BTU/hr modulating furnace with a 10:1 turn down, the lowest possible BTU/hr output of this unit is 10,000 BTU/hr.
This would mean that without doing any serious duct alterations your smallest zone should be no smaller than 10,000 BTU/hr. Same for boilers. There are some work arounds for both systems either forced air or hydronics. For forced air you can put in a supply air bypass and for boilers you can put in a buffer tank. These act as workarounds to the minimum firing rate and help mitigate the possibility of short cycling or overheating.
There is no argument than can be made against the efficiency of a zoned system − it will save energy. Which leads to the question as to why doesn’t everyone do it? The easiest culprit is price of equipment to install. It does cost something to put in dampers and valves. Is it apathy towards comfort in some systems that keeps us from making zoned systems the norm? I don’t think so.
I think the reason we shy away from zoned systems is a misunderstanding on complexity of the zones themselves and its incorporation with the equipment. As stated above, the operating characteristics of the heat source may limit the ability to zone even though there are workarounds in nearly all cases. They are simply not well talked about, taught or understood by installing contractors.
When it comes to selling zoned systems, we know it saves energy and we know it can be done so why don’t building owners scream for zoned systems to be installed everywhere?
In the commercial world there is zoning on nearly every single job. The exception being warehouses and self-storage joints. We zone in nearly all custom residential. In fact, we zone nearly everywhere with the exception being residential construction and even then, we are seeing it more in some of the higher end new construction homes with hydronic hi-v air handlers becoming more common place. The issue seems to be with residential furnaces. That’s where we seem to fall off the scale and unfortunately the most common way of heating a home at this time in Canada is a forced air furnace.
Buffer tanks help mitigate the possibility of short cycling or overheating.

IT’S ALL ABOUT THE PRESSURE PLUMBING
Whenyou live on a farm, water is very precious because it is drawn from the aquifers found either shallow or deep in the ground. These aquifers have a drawdown limit according to well yield. When the pump is pumping water, it develops a drawdown which is the distance in feet or metres the aquifer of water lowers.
Nowadays, sustainable water is more important than ever before, hence drinking water and water used for washing are the main uses of well water. If the well is producing 11 GPM of water it is a pretty good well. This is what we call well yield.
I’ve seen some wells only yield one GPM − that is not very good. In that case you need a large pressure tank, preferably a diaphragm tank, so that the pump does not run too often.
PRESSURE SWITCHES
Pressure switches are used on 1-pipe shallow well pumps, 2-pipe deep well jet pumps, and deep well submersible pumps typically in rural applications. A shallow well generally means no deeper than 25 ft. deep at sea level. Once you go past 25 ft. it then becomes a deep well pump and you could use either a two-pipe jet pump or a submersible pump.
In any case, you would still require a pressure switch for each of these applications. Let’s talk about pressure switches. The typical pressure switch has a cut-in pressure of 30 psi and a cut-out pressure of 50 psi. No matter what cut-in pressure you use, whether it’s 20 psi to 40 psi, or 40 psi to 60 psi, all pressure differentials are a 20-psi difference. This means when the diaphragm tank, which is typically set two psi below the 30-psi cutin pressure, is low the pressure switch will turn on the jet pump (if that’s what you’re using).
As the pump is drawing water from the well, in this case a shallow well, it will begin to fill up the diaphragm tank. If we have the pressure switch set at 30 to 50 psi, the pump will turn off when it reaches 50 psi. Figure 1 shows a single-pipe shallow well jet pump.
typical pressure switch can be adjusted with the two springs (range nuts) which are located when you remove the grey housing. To adjust the cut-in pressure, turn the range nut or big spring down or clockwise for higher cut-in pressure or up for lower cut-in pressure. If you want to adjust the cutout pressure turn the differential nut or small spring down for higher cut-out pressure, or up for lower cut-out pressure. You may ask why is it a pressure differential of 20 psi? This is what we call the dead pan. A pressure switch limits the pump from cycling too much or turning on and off too frequently. To prevent thermal overload or cycling of the pump the run cycle should be at least two minutes to ensure the pump dissipates waste heat. The pump should not cycle more than 25 times per hour. If the pump is sized correctly the 20-psi differential is best for this cycle.

TROUBLESHOOTING THE SYSTEM
Differential pressure is used to determine if a pipeline has any clogs or contaminants as particles flow through the pump or drop pipe. If part of the pipe gets clogged it will cause a change in pressure which causes the differential pressure to increase or decrease. This will signify a possible problem in the drop line in the well.
Pressure switches’ differential is also called dead-band. It is called dead-band because it refers to the difference between the actuation point and the reactivation point in the pressure switch.
Figure 2 shows how a pressure switch works. The pressure switch senses the water pressure from the casing through an elastic diaphragm housed in the metal frame. When the pressure switch senses 50 psi it will shut off the jet pump.
What is a reverse acting pressure switch?
A reverse acting pressure switch has contacts that are normally open. These contacts open when the pressure falls and close when the pressure rises. These reverse acting pressure switches connect as a remote switch for circuits that make contact to turn off the pump preventing pump operation at low pressure. This is just an extra safety feature for the pump.
Figure 2 Pressure switch
Cut-in: Turn range nut (big spring) down for higher cut-in pressure, or up for lower cut-in
Cut-out: Turn differential nut (small spring) down for high cut-out pressure, or up for lower cut-out
What is an auto-off pressure switch?
Typical pressure switches do not possess an on/off switch. In other words, you would have to shut the power off to the pump in order to accomplish this. An auto off pressure switch has the ability to work automatically cutting in and/or cutting out the pressure, or you could actually manually shut the pump off with a lever built into the pressure switch.

KEEPING IT COOL
Preventive maintenance is always the better route to take.
It’ssummertime and along with summer comes the realization of the important part the refrigerant condenser plays in the refrigeration system. Yes, not all refrigeration condensing systems are influenced by rising outdoor ambient temperatures. Those would be units with indoor air-cooled condensers, condensers on water or other types of fluid heat transfer. We will focus on refrigeration systems with outdoor air-cooled condensers with a secondary mention to indoor air-cooled refrigeration condensers.
As the outdoor temperatures increase air-cooled condensers are getting close to their design rating and performance. With this comes added stress on the refrigeration system due to the increased heat. As the outdoor air temperature increases, the difference between the air temperature entering the condenser and the desired condensing temperature decreases. With the lower temperature difference, the condenser needs to perform at its best. When the air temperature is much warmer the refrigerant condensing temperature is warmer, which leads to the condensing pressure being higher.
For a proper operating system there are high limits for temperature and pressure that
The refrigerant condenser plays an important part in the refrigeration system.
must be met. The condenser must be able to maintain condensing temperatures and pressures within the design envelope of the compressor. Design envelope is a set of parameters in which compressor manufacturers deem it is safe to operate the compressor. There may be cases where a compressor may still be operating within a design envelope but as the condensing temperatures increase the compressor capacity can decrease so it is beneficial to understand the requirements of the system at its design envelope.
POOR OUTDOOR PERFORMANCE
Quite a while ago I was working on a self-contained, air-cooled soft drink cooler that was designed for indoor use in an air-conditioned environment. Unfortunately, this cooler was used outdoors for a temporary festival. During the festival the cooler could barely get below 45°F/7°C. The compressor was still operating within a safe operating envelope with condensing air of 95°F/34°C. The compressor capacity was such that it did not have the pumping capacity to get the suction pressure low enough to maintain an evaporator temperature to cool the higher-priced, non-soft drink beverages sold from this cooler. When that same cooler was used in an air-conditioned environment the cooler had no problem maintaining and holding a box temperature of 35°F/2°C.

KEEPING IT CLEAN
The cleanliness of an air-cooled condenser for the summertime is very important as when an air-cooled condenser becomes fouled with dirt and debris this really restricts the ability of the condenser to remove heat. When a condenser is partially plugged the debris either becomes an insulator on the condenser coil, or even worse, it can create a blockage preventing air from flowing through the condenser. This is where propertimely maintenance is vital for the successful operation of the system.
The point at which equipment owners or refrigeration technicians perform preventive maintenance in the form of condenser inspections is very important. If the condenser cleaning is getting done when there is a breakdown or a system performance issue it could be too late. Breakdowns related to poor air-cooled condenser maintenance can be a struggle, not only in terms of the severity of the repair but in the timing of the required repair. When there is service required for a break down for heat-related problems it is typically when refrigeration contractors and technicians are busiest.
Prolonged operation of a system with a fouled or dirty condenser can lead to larger repairs; refrigerant oil degradation is a big one. If there are excessive discharge temperatures the refrigerant oil travelling through the compressor with the refrigerant can break down and lose its ability to properly lubricate. This can lead to possible compressor failure.
Another problem that is often unnoticed with a partially fouled compressor would be an increased compression ratio. This is the ratio between suction pressure and discharge pressure. As the condenser is partially blocked or dirty its
When a condenser is partially plugged it can create a blockage preventing air from flowing through it.
ability to reject heat is lower and this leads to increased pressure of the discharge. As the compressor discharge increases the compressor ratio is higher. When this happens, the compressor requires more power to run due to the increased pumping load on the compressor. The end result is a higher electrical cost to operate the compressor.
EDUCATING CUSTOMERS
It is not always within the ability of the technician or contractor to perform suitable preventive services. Some equipment owners tend to be less proactive on this topic and the technician or contractor ends up working on a reactive basis. Sometimes in the situation when a failure has happened, especially a failure that led to larger more expensive repairs, equipment owners come to understand the value and importance of performing preventive maintenance services even if it’s as simple as air cooled condenser cleaning. If you have the opportunity to help a customer or equipment owner know the benefits of basic maintenance and condenser cleaning, pass on the information. This will help them decide to complete proactive work, which is better for the sake of their equipment and their refrigerating requirements.
If you are out there working and see a condenser that is partially blocked, look at repairing and cleaning it if you can. Sometimes a quick brush off of a built-up surface can help tremendously to prevent a break down and give you time for a good thorough cleaning or power washing.
Summer is here; stay cool, stay hydrated and do what you can to keep those air-cooled condensers clear.
Prolonged operation of the a fouled or dirty condenser can lead to larger repairs.

The ultimate guide to radon instruments
There are many different radon testing/monitoring instruments to choose from nowadays. Prices for radon instruments vary widely, and they can cost from $300 up to $15,000. Basically though, “you get what you pay for.” There is no magical instrument that will work everywhere.
Major differences in capacity and function
In general, more affordable instruments have a smaller chamber and detector, which means they may have trouble measuring changes in radon levels with sufficient margin of error in time intervals of under one to two hours. It is, therefore, not possible to change measuring points quickly with that type of instrument. However, a more basic instrument may be absolutely fine if you want to measure daily variations, or measure radon levels during work hours. An electrostatic collection of decay process using a semiconductor may be fully adequate for radon studies and property owners who want to keep a check on radon levels over a long period.
Professional radon inspections
On the other hand, if you are a radon consultant who works in radon testing or radon mitigation, you should expect to invest in more expensive instruments with a larger pulsed ionization chamber/detector including a spectrometer function, which can produce measurements with an acceptable margin of error within 15 minutes. The reason is 70 per cent of the signal is coming from radon gas (Rn-222) in the used energy window for detection and only 30 per cent is coming from the radon progeny (Po-218) in equilibrium with the radon gas.
With an instrument like this, you can also quickly move measuring points and deal with high levels of radon at penetration points. This is because the instrument constantly separates unwanted contamination of radon and its decay products from the previous measuring point. Put simply, without an instrument like this, it is impossible to perform professional radon inspections.

Always choose an instrument based on application
Radon instruments have all kinds of names. If you’re new to the radon sector it can be a bit of a jungle, but fundamentally it’s all about what the instrument will be used for. If you work as a radon testing consultant, you will probably need a combination of radon instruments. Property owners too may require more than one instrument. This depends mainly on how much of the measuring work you want to do yourself, and how much you want to outsource.
When you invest in an instrument, it is vital to clearly define your intended application, both now and in the future. Ask yourself the following questions:
The application will influence the selection of a radon instrument.
Is radon being measured indoors or in the ground?
How often will I need to move the instrument between different measuring points?
How often do readings need to be taken?
How many measuring points need to be measured simultaneously?
Why is the radon measurement being performed? For example, is it a pre- or post-mitigation measurement?
By David Innes
Measurement data
The measurement chamber and detector are the heart of any instrument, but how the instrument communicates is just as important, that is how the measurement data is shown and how the software works. How can measurement data be exported? Also, which time intervals can be presented in the form of graphs? Do the measurement results indicate a margin of error? What reports can be generated?
How well the software is adapted to your way of working (on measuring radon) is hugely important to how efficient the process is once the measuring has been done. You will save time if the software can generate the measurement report you need, rather than having to export the data and then compile your own report. So, one important tip is to think about how you work today and how you want to work in the future and then determine the software capabilities of different instruments. Before you invest in an instrument, always ask for a demonstration of the software.
Calibration is essential to precision
Calibration entails setting the instrument to a known radon source, which essentially means checking and adjusting to ensure the radon instrument measures correctly. The instrument should initially be calibrated at the place of manufacture, and once a year thereafter. This is because measurement chambers and detectors become contaminated by radon gas decay products, and consequently efficiency and energy calibration must be carried out, along with background adjustment.
Most jurisdictions have some kind of requirements for this, understandably. After all, producing incorrect measurement results defeats the whole point of measuring radon in the first place. In the worst case, human health may be put at risk, especially if high values have not been identified. Even so, calibration is often neglected. Some instruments are not designed to be calibrated again after manufacture. This essentially means that you have to buy a new instrument every year to ensure accurate readings.
Therefore, always request a calibration certificate from the manufacturer. As a radon consultant, you should have your instruments calibrated annually. If you are a property owner engaging a radon consultant, always ask to see the latest calibration certificate for the instruments they will be using. It’s also important to check the supplier you buy the instruments from has an organization that can deal with calibration and any servicing requirements.
