Demand Controlled Ventilation
5 Reasons to Switch to a CO2-Controlled HVACR System
New builds and retrofits can both take advantage of the benefits of Demand Control Ventilation utilizing a carbon dioxide monitor. Here are 5 reasons adding CO2 control to an HVACR system can save energy and money.
- Indoor Air Quality - CO2 sensors answer the "fresh air" problem of modern, sealed buildings
- Occupant Comfort - Controlling CO2 levels creates a much healthier and pleasant work and living space
- Equipment Life - Running DCV only when people are present reduces the wear and tear on the entire HVAC system
- Cost Savings - Energy savings of up to 30% are reported for DCV systems
- LEED Accreditation - CO2 sensing can assist in LEED certification, which may include tax breaks and incentives
What is CO2-controlled ventilation?
CO2-based DCV systems control the amount of supply of outdoor fresh air in a building depending upon the number of people and overall activity. Because people are the main source of carbon dioxide in an indoor building, if the number of people is doubled, the CO2 levels will also double.
What are the CO2 levels for demand control ventilation?
Standards from OSHA and other organizations generally set a limit of 5,000ppm. While Canadian standards establish a lower limit of 3,500ppm. These are legally enforced.
The CO2 controllers below are also designed to work with industry-standard systems, including 0-10V or 4-20mA control and industrial relays. While each has unique specifications depending on the application, they are all designed not only to improve the health and well-being of your clients but to save them money as well.
