Key performance metrics for energy and facility engineers (part I)

We live in a digital, data-driven society. In an interview in 2019, Antonio Neri, president of Hewlett Packard Enterprise Co., stated, “We live in an incredible time — every business has been disrupted by the digital transformation. The core of that transformation is the explosion of the data we are creating. We call data as the new currency.” Buildings and their systems offer a wealth of data; however, data is useless without critical review and analysis.

These not only include energy usage, but also asset maintenance, indoor environmental quality and sustainability initiatives, such as the reduction of greenhouse gas emissions.

For many managers, the most important metrics relate to energy consumption and demand. If not already established, energy baselines need to be developed for their facilities. The International Organization for Standardization’s ISO 50001:2018 – Energy Management Systems – Requirements with Guidance for Use requires energy baselines be developed and defines these six steps:

  • determine boundaries: building, campus, business sector, etc.
  • establish the baseline period — typically one year
  • gather energy data (consumption by fuel) — create an energy balance
  • determine factors heavily influencing energy consumption
  • calculate energy use intensity (EUI)
  • track and report progress

Developing an accurate baseline of energy use is critical and should subdivide the demand and consumption between the various loads within the facility. Recent editions of the most adopted energy codes (ASHRAE Standard 90.1-2022: Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings and the 2021 International Energy Conservation Code) include requirements for submetering to help identify this data. Once developed, the most common baseline metric is EUI, calculated as the annual building energy use (measured in kBtus) divided by the total gross area of the building (measured in square feet).

The accuracy of the energy baseline is important in benchmarking against peer facilities. There are several commonly used benchmarking tools, all employing facilities’ EUIs in some capacity. These include the U.S. Environmental Protection Agency’s (EPA) Energy Star Portfolio Manager, the U.S. Department of Energy’s Building Energy Asset Score and ASHRAE’s Building Energy Quotient. These tools help in comparing the energy performance of similar facilities.

In addition to energy baselines and benchmarks, there are additional metrics — energy performance indicators (EnPI) — for facilities with specific uses. ISO 50001 defines an energy performance indicator as “a quantitative value or measure of energy performance, as defined by the organization.” Examples of EnPIs include:

  • BTU per unit of product – assembly plant
  • BTU per pound of product – manufacturer
  • BTU per number of beds occupied – hotel or hospital
  • power usage effectiveness (PUE) – data centers

The EPA works with industry to develop sector-specific EnPIs. These determine how efficiently a whole plant uses energy compared to others in its industry.

Next month, I will discuss common metrics associated with asset maintenance, indoor environmental quality and a reduction in greenhouse gas emissions. Hanson has a number of dedicated engineers and energy management professionals with experience in developing metrics and analyzing same for clients and their facilities.

Water resiliency, sustainability begins with seeing all water as valuable

Humans are made of water. Waterways connect us for transportation and recreation. Rain and irrigation grow our crops. Clean water is essential for hydration and sanitation. Too much water, too little water or poor quality water can make or break everyday life for water users — which is to say, everybody.

The US Water Alliance aims to install One Water as the standard approach for water management in the United States, with the goal of creating thriving local economies, community vitality and healthy ecosystems.

One Water is not a new perspective. One of the first ways children are taught to conceptualize water is through the water cycle. However, traditional water planning tends to disregard the cyclical nature of water. Regulatory, financial and government silos prevail, separating drinking water, stormwater and wastewater.

To adopt a One Water ethic, water planners and users must approach present and future water challenges, such as ecosystem degradation, water scarcity, climate change, flooding, aging or inadequate infrastructure and water affordability with the following hallmarks:

  • Start with a mindset that all water has value. There is a finite amount of water on the planet. Every drop counts, from agricultural runoff to reservoir contents, and every drop has an opportunity to be managed sustainably.
  • Explore solutions that achieve multiple benefits. Ideal One Water solutions find a balance between economic, social and environmental priorities.
  • Employ a systems approach. Avoid the traditional silos and acknowledge the complexity of water resources. Neglected water or wastewater infrastructure can create contaminated waterways. Treated wastewater effluent can become the environmental flows necessary to sustain vital habitats. Each water resource is interconnected and interdependent.
  • Think and take action at the watershed scale. Zooming out to the watershed level acknowledges the unique geology, hydrology, challenges and opportunities that a community may face. It is at the watershed level that the extent of a water issue can be better understood and better solved.
  • Include and engage all stakeholders and partners. The path to a resilient, water-equitable future requires collaboration and partnerships between all water stakeholders (water utilities, industry, agriculture, citizens, etc.). A diversity of perspectives ensures that needs are heard from all arenas and buy-in extends to the public.

ASHRAE’s global summit aims to improve HVAC&R issues

Aerial view of Istanbul at night

In October, I joined over 200 representatives from the heating, ventilating, air conditioning and refrigerating (HVAC&R) industry for a global summit hosted by ASHRAE’s Region-at-Large in Istanbul. The summit attracts people from all facets of the industry — designers, owners, operators, commissioning providers, contractors, manufacturers and professional organizations from around the world — and focuses on the top issues facing HVAC&R. This year’s summit addressed concerns with topics titled “Decarbonization,” “IEQ/Wellness,” “Food Security – The Cold Chain” (the temperature-controlled supply chain), “Climate Crisis Mitigation,” “Energy Security” and “Workforce Development.”

Bringing such a large group of HVAC&R professionals together to discuss these challenges offered a great opportunity to help the industry. After keynote speakers delivered short presentations on the topics, everyone was divided into groups, each joined by an industry expert, to discuss the issues, find their causes and deliberate the ramifications.

I participated in the group that discussed indoor environmental quality and wellness in buildings, and I drew on my experience as a voting member of ASHRAE’s Epidemic Task Force and former chair of its Environmental Health Committee. I found that with the wide range of personalities, experiences and expertise in these groups, the toughest part was making sure to focus on just identifying the problems. The biggest takeaway from my group’s discussion is that everyone is struggling to find the balance between indoor environmental quality (IEQ) and the energy and carbon it takes to provide a comfortable and safer environment than the code-minimum design.

After each group presented their thoughts and answered audience questions, they developed action plans, which became a fairly detailed work plan not just for ASHRAE, but for the entire HVAC&R industry. The audience then provided additional feedback and input on the subject areas for the groups’ proposed plans. The leaders of the breakout groups took this work and input from everyone at the summit to detail the plans for the summit’s final report. You can learn about everything that was presented and discovered during the summit in the report on ASHRAE’s website. The intent is that all the supporting organizations in the HVAC&R industry will adopt these plans to help improve these important issues.
