The Energy Waste Sensei — Manufacturers’ Top 3 Areas to Look for Energy Saving Opportunities

Previously from the Energy Waste Sensei: We introduced the idea of looking beyond hardware for solutions to your energy consumption challenges. (G+ users can find this post here: http://ow.ly/bFkW30cgFOn ). Now let’s explore operations in a new light: Here are Sensei Bruce’s top 3 places to look to identify energy waste!

Reducing Operations Costs, Especially from Energy

In operations, there are three major cost pieces to manage, which are labour (contributing 10-15% of costs on average), raw materials (making up 40-50%), and energy (another 40-50%). So, on a side note: Would it make sense to lay off employees when they contribute only a fraction to the cost of operations? I digress…. However, it is a topic we will discuss in the future as it ties into the 8th waste in Lean Manufacturing – the knowledge your operation has from its people if it doesn’t go utilized to its full potential!

Now here’s what really makes sense: Removing real waste from your operation, both from a material sourcing and consumption perspective, and from an energy consumption perspective. Regarding the energy perspective, you’re talking to the expert on that one!


Breaking Down Manufacturing Data for Meaningful Energy Insights

How can we reduce our energy cost? Well, if you recall from my previous post (on G+: http://ow.ly/r3mw30cgGue ), we always start by understanding our energy profile first through data stratification. I will help you with this today.

Operations energy allocation can be found under these three top categories for equipment effectiveness, which show you the best places to look for unnecessary energy use:

1. Availability of equipment,

2. Performance of equipment, and

3. Quality of its output.

Within each of these categories, there are two sub-categories of areas to look for energy that’s going to waste, which are, respectively:

Stops, both planned and unplanned,

Small stops and slow cycles, as well as

Production rejects and start-up rejects.

Each one of these energy waste opportunities can derive a long list of energy process improvements that can significantly improve your consumption of energy through reduction efforts and peak management strategies.

Are you thinking of implementing some energy storage in your building? Here are some pointers for how to get started:
The Energy Waste Sensei — To Battery or Not to Battery

My last post (which Google+ users can find it here on CoEng’s profile: http://ow.ly/TXTE30ccg6a) touched on how phase change materials (PCM) can provide exceptional energy savings both in cooling and heating. The driver, of course, stems from our discussion regarding our energy profile (shown below), and what we can do to reduce and/or shift energy consumption during peak times. In today’s lesson, we will explore what to do with the remaining energy load during peak.

See Figure 1: Low Cost Gets You 35% More Off Peak!

Recap: Leading Up with the Most Cost-Effective Ways to Reduce Energy Use

Before jumping to that solution, let’s do a quick recap of what we’re trying to accomplish overall. If you remember from my previous posts (particularly this one: http://ow.ly/fO4g30caGet), you might recall that we have taken an approach that alters our peak energy profile, allowing us to gain maximum cost effectiveness while still reducing consumption in our total energy profile. Remember to always follow the path of lowest cost first before committing further to any major capital expenditures.

When we look at our energy profile, we can see that what we need to manage from a capital expenditure perspective is significantly less than when we first started with our energy profile. By employing a strategic lean thinking mindset, we have been able to reduce consumption in this profile by roughly 66% without spending any major capital.


What to Consider Before Deciding on Batteries

Now, what about this hot, new topic everyone is talking about: batteries? Are we ready to implement battery storage now? Well the answer is: It depends! First off, now that you are an Energy Waste Ninja, it is up to you to tell the battery vendors what you need in a battery system – not the other way around. Batteries are certainly an option as a peak shift strategy but you must be in control of why, for what, and for how long you will need the system. So, for instance, if we follow our lean mindset it would be advisable to stratify our data even further for this final piece of our energy profile. We would want to do this to ensure we haven’t overlooked any other opportunities to reduce energy consumption within this final category of all other utilities (besides HVAC), which is depicted in the figure below. That way, when we are ready to implement batteries, we are retrofitting for an already very lean energy profile.

See Figure 2: Total Results with CoEng!

As done in our first set of data stratification for looking at all options, you may want to consider other demand reduction measures such as retrofitting to LED lighting, switching employees over to laptops from desktops, changing out old monitors, and or upgrading lunch room equipment like fridges, etc. before installing a battery system. This will further reduce the battery requirements upon implementation and ensure you are making the very best use of the new battery option!

Here's the second of our two-part post about using peak shifting strategies to lower electricity costs in your operations! If you missed the first half, you'll find it here in this Renewable Energy Community.
The Energy Waste Sensei — Peak Shifting Strategy, Part 2

(Those who want to read this post in the original blog form can find it in our Energy Waste Sensei series here: https://coengadvisors.wordpress.com/2017/04/18/the-energy-waste-sensei-peak-shifting-strategy-part-2/ )


#GetEnergized #peak #strategy #saveONenergy #buildings #energyefficiency #energyefficient #FacMan #operations #EnergyManagement #GreenBiz #GreenBuilding #Energized #EnergyWasteNinja


So how do you eat an elephant? One bite at a time! In our lesson today, we will take three bites to eliminate your highest cost: peak demand.

To build on our learnings from the first half of this blog post (which you can find here on Google+: http://ow.ly/fO4g30caGet), let’s look at the figure below. Here you can see a peak shift of 30% in energy consumption from the red plot line down to the green one, which comes simply from leveraging your building’s thermal properties. At CoEng, we can help do this for you by using the thermal properties of your infrastructure coupled with model predictive control (MPC) as a first step. (You can even read more about MPC in further detail in a previous Google+ post from CoEng: http://ow.ly/mwsc30caGoK). Our approach comes from seeing the whole elephant – not just the trunk or the leg! In other words, it’s about the BIG picture. By understanding all the parts, you can proactively cut down your waste at the lowest capital cost.

See Figure 1: NO Cost Gets You 30% Off Peak!

First of all, you must always approach your energy challenge with the idea of leveraging assets you already have. You must first think of how to best use your existing infrastructure and do more with what you have there already! Capital expenditures should be a last resort (except where forces such as regulations, obsolescence, or the like are at play). The reason for this is that, if you take advantage of your existing infrastructure to do more with less, then you will have reduced the amount of future capital expenditures on your next retrofits, which reduces those capital costs exponentially.

Our second move is to determine the next lowest cost option to continue reducing your peak demand. As we examine this profile for example, we can see that about 30% of the cooling needs have been dealt with by applying passive thermal energy storage in the beginning. In the figure below, we’ve now added in a black plot line to show the electricity draw coming from everything in the building that is not HVAC. So now we must figure out how to reduce the remaining 35% of our peak energy load that is consumed by our HVAC for temperature control. Employing active thermal energy storage is your next lowest cost option to do just that!

See Figure 2: Low Cost Gets You 35% More Off Peak!

There are many types of active thermal energy storage you could use for the third move. However, today’s lesson will discuss a particular method that relies on phase change materials (PCMs) to significantly reduce your HVAC energy requirements. So, what are phase change materials? They are those, which freeze or heat up at certain degrees, changing between being a solid, liquid, or a gas. For instance, you could use a PCM that will freeze when the ambient air reaches a warm 25°C/77°F; or conversely, one that heats up when the ambient air cools to 21°C/70°F. This technology can be used in new construction or can be retrofitted into existing buildings. In new construction, the material can be designed to fit behind walls. In a retrofit situation, it can be installed in the plenum. (For a more descriptive run-down about PCMs, we recommend checking out the Introduction section of this article from ClimateTechWiki: http://ow.ly/QqTY30caH0O). There are many ways to use such material and for specific applications, you can reach out to me, Sensei Bruce, for more information on how I can help you reduce your total energy profile by an additional 35%.

Plus, stay tuned for Part 2:
The Energy Waste Sensei — Peak Shifting Strategy, Part 1

(Those who want to read this post in the original blog form can find it in our Energy Waste Sensei series here: https://coengadvisors.wordpress.com/2017/03/30/the-energy-waste-sensei-peak-shifting-strategy-part-1/ )

#GetEnergized #peak #strategy #saveONenergy #buildings #energyefficiency #energyefficient #FacMan #operations #EnergyManagement #GreenBiz #GreenBuilding #Energized #EnergyWasteNinja


In this week’s previous Energy Waste Sensei post, Sensei Bruce demonstrated how to break down data analysis to provide a clearer view of your energy profile and he explained how to plan and take action. Next, in this first of a two-part blog post, you’ll learn how to shift your energy profile to reduce energy consumption and focus in on where you actually need to spend your time and money.

There are many factors that drive us to reduce our energy consumption. Some of these factors may include policy mandates, governmental regulations, and green initiatives, but we can probably all agree that cost to our bottom line is number one.

As we stratify our electrical energy data, there are other data elements that should be included to provide a better picture of what is happening and bring clarity to the areas where we need to focus. These elements include our cost data. As you can see in Figure 1, we’ve taken the chart from Sensei Bruce’s last post (which you can find on Google+ here http://ow.ly/FCC230ca10t ) and added a cost-time horizon to the X-axis. Now with this one simple addition to our graphs, can you see where we need to focus? Note: the cost-time horizon is based on the Ontario residential cost structure. The cost structure for industrial customers is primarily based on peak consumption during the 5 system peak hours. Other large users’ cost structure depends less on when the power is used, but more on total consumption.

See Figure 1 below: Building’s Electricity Demand Over the Course of the Day

Today’s lesson is about seeing what we haven’t already pieced together and bringing it to life. When we start the stratification process, it usually includes a large data set that doesn’t tell us very much. This is represented in the graph in Figure 2 as the total energy profile and is the biggest cost to our operation. This insight identifies an important area for impact! Before we stratified our data, we knew we had high demand (contributing to high energy costs) across a large range of time during the day, but now, we can see a narrower range of time when this high demand costs particularly more due to the higher Time of Use (ToU) rate it is billed at. We can easily see now that we should focus on learning about the energy usage in these hours of the day since demand reduction within this span of time will add up to the highest cost savings overall.

See Figure 2 below: Focus on Building’s High Electricity Demand at High ToU Rate
