ARE YOU MEASURING THE RIGHT IAQ PARAMETERS?
To provide healthy ventilation, your building must meet science-based standards for IAQ or you are not doing enough to guard against viral transmission. Per a recent article in Buildings magazine by Dan Diehl, there are four standards/parameters that most impact IAQ measurements and they should be measured, managed, and reported. Total Volatile Organic Compounds (TVOCs) Relative Humidity (RH) Airb [...]
HUMIDITY- CLEARING UP A COMMON MISCONCEPTION
Hot air has a greater capacity to hold moisture than cold air does. Therefore , heating up a building’s air temperature increases its ability to hold moisture. So, with no change in water content in the air, heating the air will cause relative humidity to fall because the air has more ability to hold water. However, water content in the air remains the same. The only way to remove moisture fro [...]
BENEFITS OF DIGITAL CONTROLS vs. PNEUMATIC CONTROLS
The initial cost of Digital Controls will be greater, but the benefits they offer provide a more automated and efficient workplace. Increased occupant comfort- much tighter control of temperature and humidity. Decreased operating costs and faster operating time- facilities personnel can view status and change HVAC set points. Controls sequences for energy savings-controls can be programmed to cont [...]
Benefits of Controls Integration
Controls integrated into one system, with customized programming specific to the unique needs of facility, can reap the following benefits: Single User Interface ¨ No more visiting multiple computer systems Energy Savings ¨ Controls programming that conditions air volume that meets the needs of the space ¨ Free cooling when outside temperature and humidity permits ¨ Quicker reaction to shifts in s [...]
Controls Systems Using Java Formatting Need To Know This
IF YOUR CONTROLS SYSTEM IS BASED ON TRIDIUM’S NIAGARA FRAMEWORK® AND THE JACE IS NOT RUNNING THE MOST CURRENT NIAGARA VERSION-N4—THEN YOU NEED TO KNOW THE FOLLOWING: ISSUE: The most current version of all traditional web browsers no longer supports Java. If your building automation system uses Java for the user interface, this means that there will be a day in the near future when your controls s [...]
Bringing Your Facility Up To Current Energy Code Standards
During our Lunch and Learn event, we discussed the following opportunities to realize energy savings and upgrade to meet the current energy code. The codes exist for a reason and for that same reason, all new construction adheres to them. You can create a building that is a “21st century state-of-the-art energy performer” without making prohibitive changes to the building envelope. DEMAND CONTROL [...]
Building Automation Energy Audit
Many times, the HVAC system is not given much thought. It might only become a focus when something goes wrong. However, an HVAC system that is not being properly controlled can account for 40 % of a facility’s energy costs, as opposed to the more typical 20% - 25% range. This is often due to improper set up and programming of the building automation system, or lack of one altogether. An estimated [...]
Controls Integration- A Smart Trend for 2017
Increasing energy and operational efficiency will continue to be a focus in 2017. Consider some of the key benefits a fully integrated HVAC Controls integration can offer: The ability to manage multiple building locations and the entire HVAC system from one web-based graphic interface A system that can be customized to deliver conditioned air volume that matches occupancy needs Remote troubleshoot [...]
Money Saving Controls Tip
Before you place a service call, you may want to check your thermostats and/or your building controls program to see they are set to the correct temperature. You would be surprised how often that happens and an unnecessary call charge is incurred. [...]
