Automated Optimization vs. Analytics: What’s the Best Path to Optimization?

Analytics packages seem to have it all. At first glance, integrated dashboards provide a snapshot of operational processes, metrics and key performance metrics (KPIs).

Unfortunately, analytics as an actual cost reduction tool in chilled water systems are limited unless a human takes action on this information to adjust operations. Optimizing the efficiency of dynamic systems, such as a chilled water plant requires action, ideally continuous action, that does not rely on manual intervention.

The optimization spectrum


The various levels of efficiency improvements

Of the four basic levels of efficiency improvements in use today, optimization and analytics are the most discussed. While they are complementary, they are not the same. Analytic and model-based strategies simply suggest edits, not action. Without automation, analytic software cannot optimize dynamic settings like a chilled water plant.

5 Steps to Communicate the Value of Your Energy Program

You’ve implemented an effective corporate energy program that’s lowered operating costs – probably in the 35-50 percent range. You’ve achieved significant cost savings, while also helping the environment by reducing your energy consumption.

But the work isn’t quite done yet. Now it’s the time to communicate both the program details and the results. You might be saying to yourself: “Talking about our results isn’t really my job, and there are other priorities on my plate.”

Don’t overlook the importance of putting the spotlight on the program’s accomplishments. An annual energy program communications plan results in significant advantages such as:

  • Gaining senior executive support
  • Sharing positive news with key stakeholders
  • Raising energy management awareness
  • Motivating employees to help with energy efficiency

There are five important steps to create a plan that will achieve these goals, according to ENERGY STAR®, an excellent resource on this and many energy program topics.ENERGY STAR can help your company communicate your energy program.

Step 1: Define the goals of the communication plan

Start the planning process by identifying no more than two achievable objectives of your communication plan. You might consider goals such as attract new clients by promoting sustainability results, get recognition from management for energy efficiency efforts and so on.

Step 2: Identify target audiences

With these goals in mind, determine your target audience – client, employees or both – and how that might affect your communication and style. Which leads us to Steps 3 and 4…

Step 3: Tailor the message

Now’s the time to map out the content building blocks. List all the key messages, such as cost savings, timelines, key stakeholders and goals, that should be conveyed. Remember to include important statistics and budget numbers, benchmarking data for comparison and team member kudos.

Step 4: Find the best way to reach identified audiences

With strong messaging, you need an equally strong delivery vehicle. Seek out your HR and communication teammates for recommendations and any corporate requirements. Potential messaging tools include:

  • Email announcements
  • Internal and/or external websites
  • YouTube videos
  • Monthly newsletter articles
  • PowerPoint presentations
  • Social media postings
  • Press releases

Step 5: Set the who, what and when

You’ve made it to the final step of the plan, but not the end of the journey. Complete the plan by determining who is responsible for each step, what resources are needed and how often you will communicate.

tekWorx Optimization is Making Headlines!

paper boy-resized-600

tekWorx was recently consulted for their Approachable Expertise® in chiller plant optimization strategies for ACHR News. In the interview, tekWorx GM Mike Flaherty outlines tekWorx best practices for simultaneously increasing energy efficiency and reclaiming cooling capacity in central plants. With this unique approach, all of the equipment used for cooling production is optimized, especially chillers which are often overlooked by contractors. According to tekWorx, ensuring that all of the cooling equipment (chillers, valves, cooling towers, etc.) is involved in the reduction strategy is key to decreasing energy costs in the long term.

tekWorx focuses its automation and control strategies specifically on these energy intensive components. Flaherty summarizes three phases used in every tekWorx project: an energy audit to lay out what should be done, what it will cost and what it will save, the installation of an adaptive control system to continually optimize total plant kW per ton and ongoing commissioning services to verify performance.

Energy Expenditures Add Up for Large Hospitals


It should come as no surprise that hospitals are among the largest consumers of energy in the country. Operating continuously throughout the year with a large fluctuation of employees, patients, and visitors passing between rooms full of energy intensive medical equipment means energy costs add up quickly. The greatest operating expense lies in the sophisticated heating, ventilation, and air conditioning systems that control the temperatures and air flow throughout the buildings and in the temperature sensitive operating rooms. According to a 2007 study, there were approximately 3,040 large hospital buildings in the U.S. averaging 644,300 sq. ft., and requiring regular HVAC maintenance and scheduled repair. Of these, 612 utilized chilled water over forced air for their cooling needs. The total kWh for these facilities was a staggering 13 billion, or approximately 21,757 thousand kWh per building. At an average electricity rate of 79₵/ kWh, the energy expenditures per building were enormous. With seven years of inflation and rising energy costs, those numbers have only continued to grow.

At tekWorx, our approach to chiller plant optimization allows chiller plants at critical facilities like hospitals to lower unnecessary energy consumption up to 50% by ensuring each piece of equipment is running at its most efficient point. This significantly reduces operating bills at such client projects as Bayfront Medical Center and Jackson Memorial Hospital (Florida). Using an adaptive control system, tekWorx continuously monitors critical system parameters in real time and automatically adapts online operations. The result; a lot less kWh, lower maintenance and training costs, and better control of overall operating costs.
