Building Optimisation Solutions

Information technology (data analytics) enables unprecedented efficiencies for businesses. Powerful analytics are helping organizations better manage supply chains, improve resource allocation, detect fraud and optimize many core business functions. Property is no exception. Buildings are equipped with hundreds of sensors and controls, but companies are leaving money on the table if they do not use this data more holistically to optimize their infrastructure. By applying the Joule AnalytiX solution you are able to reduce operating costs by optimizing HVAC loads, lower your utility bills, increase equipment life, improve tenant comfort, retention, and leasing rates; all while lowering carbon emissions.

Energy is a growing cost item and a mission-critical commodity for many organizations today, therefore its efficiency is a critical component of our client’s sustainability strategy whilst offering favorable business benefits. Energy consumption is a significant operational expense item for most industries and buildings making up about 20% of overall operating costs. While there is a growing need for energy efficiency, most organizations:

  • Will need a strategic approach to energy management
  • Will need to understand their most energy consuming assets
  • Will need to actively manage energy efficiently or effectively
  • Will need to understand what technologies are available to drive energy efficiency
  • A building’s performance deteriorates due to its age, usage, or functional adaptation to new uses. Traditional approaches, like Retro Commissioning (RCx) and/or energy audits, are point-in-time, stop-gap measures that are ineffective in sustaining a high level of building energy efficiency. Joule AnalytiX Managed Solutions, leverages Fault Detection and Building Performance guidelines, which enables our Automated Continuous Commissioning (ACCx), thereby helping the building to reach or exceed its original efficiency.

    M&V is a module within the platform used to accurately measure the savings obtained from the software. To assess the effectiveness and determine its value, it is critical customers be able to measure savings. This requires processes and methods that are clear, transparent and robust. The M&V module gives customers a tool to accurately measure and visualize the resulting savings. M&V uses processes that are well documented and consistent with the industry-standard International Performance Measurement and Verification Protocol or IPMVP. To identify savings attributable to the application, evaluators or project stakeholders compare baseline conditions to actual conditions—the past to the present. Results are presented in real-time using online dashboards and reports.



    "The cost savings driven by the Joule AnalytiX products was impressive. They were able to reduce operating costs by optimizing HVAC loads and recommending control sequence changes. Owners and operators should consider UCtriX when looking for cost saving options.”

    • Measurement and Verification Protocol (IPMVP)

      RETROFIT M&V - IPMVP OPTION B

      If energy efficiency measures are to make a significant contribution to environmental sustainability, measurement and verification of actual energy savings will be needed to demonstrate their short- and long-term impact. The UCtriX Group is at the forefront of instilling energy efficiency across industries, and has introduced energy savings measurement and verification (M&V) services to fulfil that purpose.

      Our M&V services adopt the International Performance Measurement and Verification Protocol (IPMVP) as the basis, which has become the internationally accepted standard for quantifying the results of energy saving. Our energy efficiency experts use this methodology as part of a broader energy efficiency measurement and verification program that covers:

      • Development of an M&V plan
      • Establishment of baseline
      • Conducting post-retrofit M&V
      • Monitoring and adjustment of energy savings
      • Issuing of M&V reports
      • Monitoring of long-term energy savings

    • Continuous Optimization

      Peak Building Performance

      Continuous optimization addresses changes in facility occupancy, use, maintenance and repair. Periodic adjustments and reviews of building operating systems and procedures are essential for optimal energy efficiency and service provision. Continuous optimization is a dynamic process intended to facilitate the efficient operation of a previously commissioned building. It repeats many elements of the standard commissioning process over a longer time period and should shorten the time intervals between operation and equipment reviews. Continuous optimization incorporates the monitoring and analysis of building performance data generated by the building automation system, or other permanently installed metering equipment, to verify high-level building performance, occupant satisfaction, and the financial outcomes of capital investments. Continuous optimization is distinct from preventive maintenance. While preventive maintenance focuses on the individual equipment or building sub-system maintenance tasks continuous optimization emphasizes systems-wide approach making sure building systems operation are understood, monitored and optimized.

    • Monitoring Based Commissioning

      Efficient and cost effective management

      Monitoring based commissioning combines ongoing building energy system monitoring with standard retro-commissioning practices with the aim of providing substantial, persistent, energy savings. There are three primary streams of additional energy savings from monitor based relative to traditional RCx:

      • Savings from persistence and optimization of savings from RCx thanks to early identification of deficiencies through metering and trending. Several studies have shown that RCx savings can degrade without an explicit effort to monitor and maintain them.
      • Savings from measures identified through metering and trending during the initial commissioning effort i.e. measures unlikely to be found from RCx alone. Haves et al. [2008] provide several examples of such measures, e.g. poor control of chilled water distribution to air handlers; unnecessary chiller operation due to disabled chiller lockout; poor VAV zone control due to inoperative actuators on air dampers and hot water valves, etc.
      • Continually identified new measures. By virtue of the continuous nature of the monitoring, MBCx can identify new problems that emerge after the initial retro-commissioning investigation stage, such as equipment cycling and excessive simultaneous heating and cooling.

    International Performance Measurement and Verification Protocol

    How are you going to measure it?

    Background
    • Most energy efficiency projects are embarked upon with no consideration of how the results will be measured. This may be due to the additional cost of measurement & verification (M&V), the complexities involved, or simply that M&V falls between the cracks and is forgotten about until the project is completed. The upshot is that a great many projects have an ambiguous outcome, and sound energy efficiency measures are rejected or neglected because they remain ‘unproven’. Often, if the energy bill does not come down, an efficiency project is considered a failure, when in reality other factors (the weather, for example) may have masked the savings by causing energy use to increase.
    • IPMVP helps to tackle this problem. It provides a framework for ‘good M&V’ without being too prescriptive, so M&V solutions do not have to be expensive or overly complex. Developed in the mid-1990s by the US Department of Energy, IPMVP is now the most widely used and recognised M&V protocol in the world. Having been developed with ESCO contracts in mind, it defines a common sense approach to M&V, and is perfectly placed to help improve the credibility and attractiveness of energy efficiency projects. IPMVP is managed worldwide by EVO (Efficiency Valuation Organisation), and much more information is available on their website.
    Good and Bad M&V
    • The most common approach to determining energy savings is to compare two periods before and after implementation of the ECM (Energy Conservation Measure). This generates a saving number, but this is only valid if the two periods happen to be directly comparable. In many cases they may not be, so the savings figure is meaningless.
    • We believe this practice is giving energy efficiency (EE) in general a bad name. EE should be recognised as a source of clean energy in its own right, but while there is a question mark over the validity of the savings assessment, this will not be achieved.
    IPMVP tells us that:
    • Savings are the absence of energy use
    • We cannot measure what we do not have
    • Therefore, we do not measure savings
    However:
    • We do measure energy use
    • We analyse measured energy use to determine savings
    • This analysis is crucial. A simple comparison of averages may tell you the cost reduction over the period you are looking at, but an energy saving is actually the avoided energy use. So the saving tells you how much less you have used than you would have without implementing the ECM. Consequently, IPMVP’s governing equation is:
    • Savings reported for any period = baseline period energy - reporting period energy ± adjustments
    • The ‘adjustments’ part is where the analysis comes in. To give a fair evaluation, we need to consider the factors that drive energy use on the site we are analysing. For example, a common factor is the weather, which governs how hard heating or cooling equipment must work to provide a comfortable indoor temperature. Accounting for these ‘externalities’ using a regression analysis is often a key part of an IPMVP-adherent savings analysis, or alternatively we may ‘zoom in’ and look closely at the ECM itself rather than the whole site. We also have to build an understanding of how the site uses energy, so we can account for any sudden changes in energy use and ensure these do not affect our evaluation.
    • This kind of analysis allows us to isolate the effect of your ECM and quantify how much it is saving. Importantly, the analysis and modelling should be done before the ECM is implemented, making M&V part of the project from the outset. So an IPMVP analysis comes in two parts:
      1. The M&V Plan. The site is analysed in detail, and the plan commits to a methodology for determining the savings from the proposed ECM
      2. The savings report. A final analysis quantifies the avoided energy use, in line with IPMVP’s governing equation.
    • Any M&V strategy that does not have these two ingredients could be open to ambiguity, or worse, abuse, as the savings analysis will simply be thrown together after ECM implementation.
