How do you answer "What do you do?" 

Changing perspective might be your game changer. It certainly was ours.

“Helping Leaders Create Better Working Environments for Hard Working People” is the message on the home page of our website. It signals for the reader, the answer to the question, “What is it that you do?” For years, we answered that question by saying that we are an HVAC manufacturer. Technically, that is true - however, “What we do” is help business leaders support their people by delivering a system along with our equipment that creates comfort and well-being for an organization’s most valuable asset – their people.

Leaders support their people through comfortable indoor temperatures? How?

Facility and operational leaders can make an impact on an employee's health and employment satisfaction by focusing on the quality of the environmental conditions in which they are working. In our HVAC world, it’s about providing fresh outside air ventilation for improved indoor air quality (IAQ) to evenly heat manufacturing and warehousing spaces during the winter months and to provide cooling during the summer months. To provide an example, in our own manufacturing facility, we know the toll that the hot and humid St. Louis summers have on our people and are taking the steps to install and operate a two-stage (Indirect/Direct) evaporative cooling system to lower temperatures in our factory. These evaporative cooling and ventilation units will boast a dramatic operational cost difference compared to traditional mechanical or DX cooling systems, but that is merely a perk to making the plant temperature more comfortable for our employees. More comfort translates into more joy at work. More joy means more people engagement, more employee genius and more fun.

The difference between “What you do?” versus “Who you do it for?”

In Patrick Lencioni’s book "The Advantage,” he challenges business leaders to invest significant time in the development of organizational health. Patrick states, “an organization’s health trumps all strategy.” We agree wholeheartedly. While we work on sales and technological strategy, we recognize that our work on organizational health is first and foundational.

We talk about organizational health frequently. We invest in organizational health continuously through our lean methodology that includes daily meetings with the whole organization and a time commitment made to improving things every day. The organization blocks time out for everyone to work on improving their job daily. This time commitment to improvements as a daily rhythm puts people in contact with one another to solve problems and collaborate on solutions.  Whether a process improvement, safety improvement or product improvement, we are working to improve the quality of our customer’s experience with our brand. Ultimately, a better working environment translates into superior quality and performance of our products for our customers. One’s working environment can have a big impact on the organization.

We welcome business leaders to come visit us in Chesterfield and share your great ideas on how you are investing in better working conditions for people. Come and see us and let’s continue the conversation.

We applaud any leader's commitment to an improved work environment for their employees, and recognize the huge investment that this commitment can take. Since the heating, cooling and air quality of a building can play such a major factor in a happy and productive environment, we wanted to provide you with some simple mid-year maintenance tips to make sure your commercial and industrial HVAC systems are in check.  Below you can find some recommendations from Ryan King and Mike Bess, members of the Cambridge customer service team.

  1. Check the air filters.  Clean these filters if necessary because dirty filters will reduce CFM and could damage the discharge air sensor. 
  2. Grease the bearings.  The grease should be evenly distributed around the race; however, do not use the standard bearing grease in the Baldor motor.  This motor takes special grease that can be referred to in the technical manual.
  3. Check the belt tension and inspect for wear.  If the belt is too tight, it can  prematurely wear out the bearings and the belt.  If the belt is too loose it can slip or squeal.  
  4. Cycle the unit on and off in all modes of operation.  This ensures things are working per specifications.
  5. Check the discharge temperature.  Use a wired thermistor at the mixing box and calibrate the system if necessary.
  6. Inspect the control panels.  Look for any loose or frayed wire connections and make sure all connections are tight.  
  7. Check and clean the evaporator and condenser coils.  Dirty coils will drastically reduce cooling equipment efficiency and strain the compressor. 
  8. Perform a gas valve leak test.  This verifies the integrity of the valves.
  9. Verify that the manifold differential gas pressure matches the nameplate.  It is extremely important that this is set up properly.  If the manifold pressure is incorrect, the heater temp rises and its efficiency will be affected.  
  10. Inspect direct evaporative media (CELdek).  Ensure that there is proper water flow across the media. 
  11. Check the calibration of digital thermostats.  Press the up arrow and hold it; the display should show 0F.  If not, the calibration may have been adjusted to show a warmer or cooler temperature than desired.

We know you’re busy, and sometimes the easiest way to get direction on a service question or instructions on how to install can best be obtained by a quick “How-To” video.

“Comfort” is an interesting word that we use a lot at Cambridge.  Since we are an HVAC company, it is usually in context with making sure the people in your industrial facility are breathing fresh, tempered air, or making sure that your employees in high-bay buildings aren’t freezing in the dead of winter. There’s also “comfort” in the realm of making sure your employees know that you’ve got their backs and have a genuine interest in their personal health and professional growth.  (see blogs on Dale Carnegie Leadership Training and Stretching Your Way to Workplace Safety to generate ideas of how to boost comfort both personally and professionally).
 

Still, most companies overlook the importance of physical employee comfort, and are losing real talent and real opportunity to grow with those employees when they leave to pursue a workplace that can meet and exceed their basic requirements of a healthy working environment.
 

Not convinced? Here are four reasons that we think will back us up.
 

Safety protocol alone is reason enough.

According to OSHA – your workers have the right to working conditions that do not pose a risk of serious harm.  The OSHA website starts with a dire warning: “The quality of indoor air inside … workplaces is important not only for workers' comfort but also for their health. Poor indoor air quality (IAQ) has been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, throat and lungs.” This safety protocol is actually far, far above a “comfort” suggestion – and could be downright dangerous if ignored.
 

And even though we could stop after the safety reason, here are three more reasons to consider:
 

You can’t exist without them.

Unless you are a completely automated company or self-employed, you depend on at least one employee to get your product or service sold, produced, billed, you name it. Employees know that they have employment options – especially in trade professions, where there is a serious labor shortage. Don’t doubt that even if an employee feels fairly compensated, they might still leave because of continuing discomfort in their workspace.
 


 

Continuous improvement falls apart when it’s not the priority.

Imagine a humid July day in a distribution facility, when you can’t imagine doing anything but cooling off. We spend a portion of every day identifying opportunities for lean improvement in our processes and workspaces, but even we know that these can fall by the wayside when it is just too hot or too cold.
 

They are your brand ambassadors.

Client services to your customer.

Seasoned laborers to new hires.

Any employee to the world on social media.

Your employees can and should be your biggest advocates, because they are treated right (and physical comfort plays a big role) and believe in your product or service. The opposite of these two things can destroy every sales opportunity on your books this year.

There are so many ways to make your team feel comfortable – and they deserve it, so make it a priority to figure out the right investment to provide them a workspace in which they can reach their full potential.

According to the Environmental Protection Agency the average American spends 93% of their life indoors…. 87% is spent indoors at their work and home and the other 6% is spent in their automobiles. With that much time spent inside we should all be more concerned with Indoor Air Quality. Recently Cambridge Engineering’s Doug Eisenhart published a post about IAQ that focused on the effects of temperature and productivity of a workforce because ambient air temperature is an IAQ factor. Doug was spot on with his comments about productivity and its correlation to temperature. Along with temperature the quality of the air from indoor pollutants is also an important IAQ factor that needs our attention. Pollutants such as volatile organic compounds (VOC), particulates and carbon dioxide, to name a few, can not only affect short term productivity but can also have long lasting negative health consequences to those working in that environment. One way to alleviate these types of IAQ problems is to have the building properly ventilated through the use of mechanical ventilation of filtered outside air. By using High Temperature Heating and Ventilation (HTHV) products that use 100% outside you have the ability to not only heat the space but also ventilate the space in an effort to help reduce the types of indoor air pollutants that can sometimes cause serious health problems. HTHV products, when combined with appropriate air filters offer a very energy efficient way to heat and ventilate a structure during the winter months when bringing in outside air is the most problematic. There is plenty of information available that can provide guidance on indoor air quality and ventilation. Here are two that I have found useful: 1. OSHA publication titled - Indoor Air Quality in Commercial and Institutional Buildings can be located on OSHA’s website at https://www.osha.gov/Publications/3430indoor-air-quality-sm.pdf 2. ASHRAE publication titled - Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning is a free publication located on the ASHRAE website at https://www.ashrae.org/resources--publications/bookstore/indoor-air-quality-guide. The guide is designed for architects, design engineers, contractors, commissioning agents, and all other professionals concerned with indoor air quality. ASHRAE also has available for purchase their ANSI/ASHRAE Standard 62.1-2016 Ventilation for Acceptable Indoor Air Quality. Standard 62.1 specifies minimum ventilation rates for new and existing buildings that are intended to provide indoor air quality that is acceptable to human occupants and that minimizes adverse health effects. This publication is located on the ASHRAE website at https://www.ashrae.org/resources--publications/bookstore/standards-62-1--62-2. Let us know what you think about the IAQ subject and look for more post on Indoor Air Quality in the future.

For the last 3 years my team has been traveling North America visiting with Cambridge Engineering’s, Sales Representatives to spread the word about options available to Building Owners, Building Operators, Design Engineers, Contractors and Utilities when recommending and selecting heating and ventilation solutions for their building or retrofit projects. 419818 We have been attempting to call out 3 core concepts for the key influencers when considering improvements to their buildings. 1.) Safety - Use of 100% outside air, direct fired HTHV and MAU technology is inherently safe. Ventilation and Heat are provided by the same blower that cannot be separated. These technologies can improve indoor air quality. Ventilation is the key to safety, preventing the buildup of products of combustion. 2.) Energy Efficiency - HTHV technologies provide the highest btus/cfm ratio thus creating more net useable btus or heat to satisfy the air load and the conductive load in high bay warehouses, distribution centers and manufacturing facilities. 3.) Lowest Total Installed Cost - HTHV technologies deliver 3 system in 1 piece of equipment. HTHV technologies deliver A.) Heat, B.) Fresh air ventilation and C.) Even temperatures throughout the building. This 3-in-1 system reduces total equipment cost and the installation costs associated with connections necessary to install multiple pieces of equipment. Engineers may call this a cleaner design. During our recent Contractor Advisory Board, an influential Design Build Contractor, Paulson-Cheek (Atlanta, Georgia), called us out on our failure to identify THERMAL COMFORT as a primary value in his selection and use of HTHV equipment in his high bay building designs. I’d like to share a brief video from Marshall Cheek regarding his comments on this subject: 

 Marshall’s callout on Thermal Comfort was very insightful. We often undervalue the importance of building occupant comfort in a cost competitive new construction or retrofit building environment. Understanding the importance of creating a safe and comfortable working environment for people engaged in the real physical activity such as: warehousing, distribution center and manufacturing facilities, compels us to add this 4th leg to the table.   safety Are people more productive when their workplace is comfortable? One ergonomics expert, Chris Adams, who in addition to being a Human Factors Engineer & Industrial Designer, has been providing human factors engineering to NASA, states that: temperature has a major impact on productivity. According to one of Chris’s articles, 71.5 F is the optimal temperature for 100% productivity. His report details the following information: As temperature increases at: • 77 degrees fahrenheit we're about 98% productive • 82 degrees fahrenheit  = 95% • 87 degrees fahrenheit = 90% • 92 degrees fahrenheit = 85% As temperature decreases at • 66 degrees fahrenheit we're about 98% productive • 63 degrees fahrenheit = 95% • 59 degrees fahrenheit = 90% Soliciting solid Building Owners and Building Operators’ input during the design phase of one’s building project makes sense, according to this report. Adding personnel comfort level to our discussions and being able to articulate the impact that consistent temperatures may have on people’s productivity is beneficial. Inherent Equipment Safety, Energy Efficiency, Lowest Total Installation Cost and People Comfort are all important topics of discussion when discovering what is most important to owners and operators. People Comfort is high on my list of questions. What does a 5% gain in productivity mean to an organization in real dollars? Answer this question and compare it to an investment decision and it makes for better decision making in an equipment selection. Thanks for sticking with me to the end here. How important have you found thermal comfort to be in your conversations regarding HVAC design? Does the same hold true for people working in the warehouse? Should it? 71.5d egrees fahrenheit sounds good right now as it’s 100 degrees fahrenheit in St. Louis as I write this blog post.
