    3. You will be taken to the On Demand Webinar Page, click the link on the page to access On Demand Webinars search page.
    4. In the search box type in all or part of the the webinar title:Harvesting Hidden Energy Savings: CO2 Demand Controlled Ventilation
    5. Click to register to view the seminar when it appears in the search results. 
    6. You should be able to view the webinar immediately.
    This webinar is intended to provide facility managers a firm understanding of the history of CO2 demand controlled ventilation and its evolution to a main stream energy savings methodology for buildings. 
    By attending, you will:
    • Be provided with unique Canadian perspective on how to quantify savings in Canada
    • Learn how CO2 demand control ventilation can be integrated in your current facilities
    • Understand the role of economizer control in optimizing DCV in building performance
    • Predict energy savings resulting from a CO2 controlled strategy
    • Review Canadian case studies that show energy savings in retail applications
    • Examine rebate opportunities for retrofits for CO2 DCV energy in Canada
    Note: Even though this webinar has a Canadian Focus it is highly relevant for US based locations.  In fact in cooling dominated climates, energy savings are considerably more than experienced in many Canadian locations.  Savings occur for both heating and cooling.  Utility rebates for this technology is available in most jurisdictions. 
  • What is CO2 DCV

    CO2 based DCV allows buildings to save energy by modulating outside air delivery based on real time occupancy rather than providing constant ventilation at full design occupancy.  Energy savings can range from 15 to 50 percent or more. The biggest savings are available in applications that have high variable occupancy that can include retail stores, schools, gyms, theaters, hospitality, entertainment and sports venues.  Most utilities offer energy saving rebates for incorporating CO2 DCV.

    The AirTest Energy Analysis Program

    AirTest has developed an energy analysis program that will estimate the potential annual savings that can result from a CO2 Demand Controlled Ventilation Strategy (DCV) integrated into a building HVAC system.  The program considers local hourly climate conditions, occupancy variability, heating and cooling types, economizer strategy and energy costs to determine the annual cost to condition incoming outside air using a fixed ventilation strategy verses a CO2 DCV strategy.  The results estimate the value of savings from a proposed DCV installation.  This information will allow facility managers to estimate the potential energy payback or return on investment by adding CO2 control.  The results can also be used as technical backup for an application for utility rebates. 

     What is Involved

    The Energy analysis will be conducted remotely by an AirTest engineer and takes about 15 minutes per building to complete. It requires the participation of somebody familiar with the facility being analyzed.  The analysis can be conducted via Webconference or Skype. A short questionnaire will be provided prior to the analysis to ensure all the necessary data is available.  Here is the information we need:  

    AirTest can also train individuals in your organization on how to use the energy analysis program, which is available free from AirTest.

    To help estimate payback and ROI, AirTest can also provide a recommendation on the best products, pricing and installation approach that can be used to integrate DCV into your buildings.  We can also provide an estimation of likely labor hours.  If there is further interest we can work with your service organization to develop a detailed scope of work. 

    If you are interested in a pilot installation, AirTest offers a wireless system that can evaluate real time HVAC energy use by alternating DCV vs fixed ventilation control every 24 hours while measuring all electrical and gas energy cost.  We can make this easily installed system available for monitoring projects of two to three months to allow for determination of real time savings.  If you don’t feel the savings justify a permanent installation the system can be very easily removed.  More information on this system is available here:

    To arrange for your facility energy savings/payback analysis contact an AirTest sales person (, visit us at the PRSM Show at the AirTest Booth (215), or contact Mike Schell at 805 689-1411.


  • Feature: CN9099 Wireless CO2 DCV Retrofit For RTUs
    The CN9099 is a wireless CO2 DCV Retrofit Kit that is fast, easy and inexpensive to install on Rooftop Air Handling Units (RTUs) to enable ventilation control based on occupancy. This approach can reduce RTU energy use from 15 to 50%....

  • The Energy Saving Opportunity: Every RTU (Rooftop HVAC Unit) produced in the last 18 years has an input and control capability for CO2 demand controlled ventilation (DCV). DCV allows buildings to save energy by modulating outside air based on actual occupancy rather than providing constant ventilation at full design occupancy.  However most RTUs installed today are not connected to a CO2 sensor and therefore are missing out on the 15% to 50% savings that this approach can provide.

    The Problem:  Retrofitting RTUs with wired CO2 sensors is expensive and labor intensive.

    A Simple Solution: A wireless, battery powered CO2 sensor is placed in the space and a receiver is placed in the RTU that provides a 0-10 V signal into the RTU CO2 input. Total installation time is 30-45 minutes for one person.

    A peer-to-peer, private WiFi connection is made between the sensor and receiver. This approach does not require connection to a local WiFi network, and eliminates the security concerns of owners who want to minimize third-party connections to their network.

  • Wireless CO2 DCV Retrofit For BACnet Control
    AirTest offers two wireless battery powered CO2 sensors for Demand Controlled Ventilation for retrofit to most building control systems using BACnet or Modbus. Minimal material and labor for installation and energy savings of 15 to 50%....

  • The Energy Saving Opportunity: Most building control systems can accommodate CO2 Demand Controlled Ventilation (DCV). DCV allows buildings to save energy by modulating outside air based on actual occupancy rather than providing constant ventilation at full design occupancy.  However many buildings do not have CO2 sensors and are missing out on the 15% to 50% savings that can occur.

    The Problem: Retrofitting a building with wired CO2 sensors is expensive and labor intensive.

    Two Simple Solutions: 

    1) The TR9299-wifi, battery powered CO2 sensor is attached to the wall and broadcasts CO2 levels through a local WiFi network (can also draw power off a thermostat). The BB2-7010-06 BACnet/Modbus gateway takes these readings from the network and displays up to 200 sensors as BACnet objects in the control system. Minimal labor, minimal materials and fast installation. 

    2) The TR9277-eo is an ambient light powered CO2, Temp and RH sensor that uses the EnOcean Wireless Protocol.  Most major building control systems produce inexpensive add-on gateways that translate from EnOcean to BACnet. Minimal labor, minimal materials and fast installation.
