Join us for this webinar to understand the practical science behind the improved performance and the potential gains that can be realized in your buildings. The webinar will cover:

Why Hydronic Design Models Don’t Match Building Performance

Modelling softwares make a few faulty assumptions about basic hydronic behavior which can lead to disappointing building performance.  By selecting and installing proper equipment, engineers and contractors can be successful in achieving the modelled results.

Understanding and Improving Heat Transfer at the Coil

By understanding the thermodynamics behind the heat transfer at coils and heat-exchangers, we can devise better control strategies to better match the water flows to the specific loads in the space.  When done properly, most buildings can use far less water to heat and cool, and thus save large amounts pumping and plant energy.

Static vs. Dynamic Balancing

Until examined closely, the true benefits of advanced control valve technology, may be overlooked from a control and comfort standpoint.  By exploring dynamically balanced systems, we can see how we can hope to have more stable loops and more comfortable spaces.

Belimo Energy Valve

The Belimo Energy Valve is an electronically pressure independent valve with a fully integrated BTU meter.  It has the ability to control flow, manage Delta T, monitor system glycol percentage and fully expose the performance of the equipment.  With advanced communication platforms, which include BACnet, MODbus, IP and cloud based optimization, the Belimo Energy Valve provides unparalleled access to all of the data.

Energy Cost Savings Can Be Achieved Through Better Compliance

Posted on Thu,Oct 20, 2016 @ 09:15 AM

A recent Department of Energy study1 conducted by Pacific Northwest National Laboratory (PNNL) investigated the lost energy savings in small commercial buildings that were not in compliance with the current energy code, in this case, IECC 2012. In energy codes, air economizers are required on most commercial air systems, whether packaged or split system. However, just having an economizer damper and associated control doesn’t result in automatic compliance. There are many subset requirements for economizers today (economizer requirements for details).Capture2.png

Although this DOE study focused oncompliance verification, it identified a common problem, 100% of economizer controls reviewed had their high-limit shutoff not in agreement with the setpoints as prescribed by the IECC for climate zone 4C. This is not a new problem. The California Energy Commission in 2003 identified that 72% of the economizers investigated had improper high-limit shutoff settings. What’s new, PNNL was able to use the US DOE commercial prototype building model to determine energy effectiveness of specific code requirements and lost energy savings for this incorrect setting. Calculations showed that the wrong high limit setting would result in additional electrical usage of $3.56 / ton per year to as much as$14.18 / ton per year. Also highlighted in the report was the difficulty in verifying if the control was set to the correct high-limit shutoff in accordance with energy codes. It was noted that systems often found in small to medium-sized commercial buildings, didn’t meet the size requirements of the IECC to trigger mandatory commissioning. The verifier was well experienced in economizer controls, but still had challenges identifying setting and operation of the installed controls. In this study, thirty minutes of time was attributed to verifying the economizer control setup.

Download the complete study, An Approach to Assessing Potential Energy Cost Savings from Increased Energy Code Compliance in Commercial Buildings” by Michael Rosenberg, Reid Hart, Rahul Athalye, & Jian Zhang, Pacific Northwest National Laboratory, David Cohan, United States Department of Energy. This paper presents the results and many lessons learned on how to increase ourbuilding performance.


In summary, improper setup of an economizer leads to lost savings, and verification to validate the settings is an additional cost. With the ZIP Economizer by BELIMO, just enter the ZIP code of the building, and the economizer will automatically set the high-limit shutoff values as required in the latest energy codes.You can visually verify the climate zone and the high-limit value set by the ZIP code. (see how easy it is)

The ZIP Economizer is also equipped with other energy saving and system projection features and meets all the latest economizer control code requirements.

Latest Code Economizer Requirements

  • 100% Outside Air – Economizers shall modulate and have the capability to provide up to 100% of supply air with outdoor air when needed to meet the cooling load.
  • Pressure Relief – Means of relieving the additional outside air shall be provided to prevent building over-pressurization. Typically provided by a barometric damper or powered exhaust.
  • Integrated Cooling – which is to provide mechanical cooling with Free Cooling with the damper remaining at 100% outdoor air position and requires a 2 stage thermostat to comply.
  • Class 1 Motorized Dampers – Dampers shall have leakage no greater than 4cfm/ft2 in accordance with AMCA 500D and tested and labeled by an approved agency.
  • Economizer Fault Detection and Diagnostics (FDD) – requiring an advanced digital economizer control providing system information, status, and fault notification.

Company: Daikin Applied (; 2017 AHR Expo booth No. C2509)
Innovation: Pathfinder® Air-cooled Screw Chillers with Variable Volume Ratio (VVR) Technology

The new Daikin Pathfinder AWV air-cooled screw chiller features an industry-first Variable Volume Ratio (VVR) technology which allows the chiller’s compressor to adjust its own internal compression ratio as water and air temperatures fluctuate. With VVR technology, its compressor senses the amount of lift needed and adjusts the compression ratio automatically to provide optimal efficiency under any operating condition, equating to reduced energy use, cost of ownership, and carbon footprint. The Daikin Pathfinder AWV air-cooled screw chiller also features VVR slides that operate on the discharge side of the screw to control the refrigerant compression ratio without altering the per-stroke refrigerant volume, unlike typical capacity control slide valves.  Variable frequency drives (VFDs) are used in conjunction with the VVR slides to control motor speed, and subsequently compressor capacity.  This results in superior performance under AHRI-standard conditions, and in real-world scenarios in which air and water temperatures can fluctuate greatly.

Green Building
Company: Carrier (; 2017 AHR Expo booth No. C1510)
Innovation: Dual Stage Relief Economizer (DSRE)

Carrier’s Dual Stage Relief Economizer (DSRE) for light commercial rooftop units combines a traditional economizer with a means of relieving building pressure without the use of a power-consuming device. DSRE uniquely combines an air economizer with two non-powered pressure relief stages, facilitating the relief of pressure during normal ventilation operation and during economizer free cooling. In many applications, DSRE also eliminates the need for a powered exhaust or a separate pressure relief system, thus reducing both installation costs and building energy consumption.  In addition to the relief capability, DSRE allows customers to minimize electrical feeds and breakers for installation, and to lower their initial first cost by enabling use of a smaller electrical feed and breaker.  According to a recent Carrier energy model analysis, a typical 10-ton DSRE unit can achieve between $189 and $389 in annual savings (based on $0.12 kw/hr and between 1,200-2,400 hours of economizer operation).

Company: Noritz America (; 2017 AHR Expo booth No. C5917)
Innovation: Noritz Combination Boiler

The Noritz Combination Boiler delivers hot water for both plumbing and hydronic residential heating applications, while managing the switch between uses without a perceivable difference in performance. With 95-percent annual fuel utilization efficiency (AFUE), it is ENERGY STAR rated to deliver maximum operational cost savings to homeowners.  The Noritz Combination Boiler’s compact, 90-pound package delivers up to 9.2 gallons per minute of domestic hot water – nearly twice the flow of comparable units.  A unique flow control valve also facilitates maximum domestic hot water flow rate at stable temperatures and regardless of incoming water temperature.  The boiler’s external and booster pump drive terminals (up to 2 amps) do not require a relay, and its integrated condensing technology lowers exhaust temperatures to a level at which stainless steel venting material is no longer required.

Indoor Air Quality
Company: Nortec Humidity (; 2017 AHR Expo booth No. C4706)
Innovation: Nortec GS Series - CS Model (Nortec GS CS) Humidifier

A gas-fired isothermal humidifier producing hygienic and atmospheric steam, the Nortec GS Series CS Model Humidifier fulfills a wide range of humidification requirements for indoor environments.  Direct building management integration allows the GS CS humidifier to deliver necessary steam quantities both inside duct systems and directly into a space, thus more quickly elevating indoor humidity conditions to required set points. Its unique gas-fired operation – the first to employ condensing technology to facilitate high-efficiency performance – is powered with either natural gas or propane, allowing for flexible and economical function. Delivering more than 93 percent total efficiency, the GS CS humidifier is also first in the industry to employ a secondary heat exchanger to pre-heat water before entering the tank, while subsequently cooling down combustion exhaust gasses. The result is a reduction of exhaust gas temperatures by more than 50 percent (when compared to the current market standard-efficiency of 80 percent), thus allowing for flexibility in venting options (both BH and CPVC). A low-emissions (NX) version of the GS CS humidifier is also available, offering further reduced efficiency (>88 percent), and with low NOx emissions of approximately 7 ppm (falling within SCAQMD emissions standards for gas-fired humidifiers).

Company: Taco, Inc. (; 2017 AHR Expo booth No. N7926)
Innovation: SmartPlug Smart Hot Water Recirculation Control

The SmartPlug Smart Hot Water Recirculation Control from Taco allows for easy installation onto existing domestic hot water recirculation pump systems to more efficiently manage on-demand hot water delivery.  The plug-in 115-volt control features technology to learn and record a homeowner’s hot water usage pattern, and employ the resulting data to operate a home’s hot water recirculation pump precisely when hot water is typically required.  While hot water recirculation pumps typically run continuously or are controlled with an aquastat or timer, SmartPlug provides fully automatic and self-adjusting pump operation – only when hot water is desired.  Usage patterns are monitored and recorded on a daily and weekly basis, with the SmartPlug system regularly refreshing data and adjusting any changes to hot water usage patterns.  The result is a significant increase in water heater operational efficiency, promoting a simple yet notable way to save on residential energy costs.

Company: Danfoss (; 2017 AHR Expo booth No. C4506)
Innovation: Danfoss CTM (Electrical Controlled Transcritical Multi Ejector)

The Danfoss CTM is an electrically controlled multi-ejector designed specifically for the warm climate operation of transcritical CO2 systems in food retail applications.  Capable of recovering energy while controlling the high pressure of the transcritical application, the CTM ejector delivers value to the application through significant (20 percent or greater) improvements in energy efficiency.  This is achieved by employing energy recovered from the gas cooler and transferring it to increase the pressure of gas being compressed by parallel compressors, thus reducing overall compressor load.  As the first commercially viable solution engineered to overcome energy penalties associated with operating transcritical CO2 systems in high ambient temperatures, the CTM ejector also eliminates need for redundant, cascade refrigeration systems.  In cooler and more temperate climates, it can deliver even further energy saving benefits, with ejectors that create a low pressure at high velocities to optimize operational efficiency in a wide range of load conditions.

Company: Nidec Motor Corporation / U.S. MOTORS® (; 2017 AHR Expo booth No. C3924)
Innovation: Rescue Select Programming App

The Rescue Select Programming App has been developed to streamline programming of the Rescue Select Truck Stock motor – an electronically commutated (EC), constant torque, aftermarket motor developed for use in residential and light commercial blower motor replacement applications. Powered by a robust, cloud-based web service, the Rescue Select Programming App can be accessed via any smartphone or compatible wifi-enabled device.   The Rescue Select Truck Stock motor and Programming App work in tandem to help service contractors identify an original blower motor’s particular horsepower ratings and operating parameters (ex. torque load, fan speed, rotation direction), and program an in-stock replacement motor to mimic that original performance profile. This allows a service contractor to stock a smaller range of aftermarket motors and use them to replace nearly any original blower motor or other electrically-powered device or system.  Additionally, programming and installation are streamlined directly at the point of replacement, versus off site/in the shop. The first to provide HVACR service contractors with the ability to program a replacement blower motor at the point of installation, the Rescue Select Programming App is driven by a continuously updated database populated with thousands of motor profiles. In addition, the App provides service contractors with options to customize or develop new performance profiles that match special or unique application requirements.

Tools & Instruments
Company: PEXOLOGY, Inc. (; 2017 AHR Expo booth No. C6618)
Innovation: PEXGUN

New Product Offering: ANSI 250 Energy Valve and ePIV, an Advanced Performance Solution for Higher Pressure Applications

Posted on Wed,May 04, 2016 @ 07:31 AM

Belimo officially launched the new ANSI 250 pressure rating for 2½” to 6” flanged Energy Valve and Electronic Pressure Independent Valve (ePIV) assemblies. The ssemblies utilize an electromagnetic flow meter inline with a control valve to obtain close-off ratings from 135-310 psi depending on valve size and actuator force. Actuators respond to a modulating control signal and are available with non-spring return or electronic fail-safe functionality.The ePIV and Energy Valve both provide true flow with the built-in electronic flow meter and dynamic balancing providing pressure independent operation by maintaining constant flow regardless of differential pressure fluctuations.

The Energy Valve also provides a solution to low Delta T syndrome with its Delta T Manager™. The Delta T Manager algorithm Pressure-Independent-Comparison.jpgreduces pumping and chiller/boiler operating costs by increasing chiller plant efficiency and eliminating waste zone operation. The Delta T Manager maintains temperature differential based on a customer defined setpoint by regulating the flow using the delta T measurement across the coil.

Power control is another feature of the Energy Valve, which allows setting the power output to a specific value in a linear response making coil control both pressure and temperature independent. Additionally, the Energy Valve is equipped with an Energy Meter and data logger that stores 13 months of data providing system transparency along with the ability to optimize performance over BACnet or standard analog control.

The ANSI 250 Energy Valve and ePIV provides reliable, automatic, pressure independent flow control for high flow applications. And the ANSI 250 Enenrgy Valve does so much more – measures energy, controls power, manages delta T, communicates, trends, and diagnoses.
