In my previous article on two-system integration, I discussed the four steps for effective integration. Just to recap, those steps are:

Last month’s column introduced the concept of giving “too much control” to the building operators through the BAS graphic.

DuctSox says its new C-Series Fabric Diffuser offers a 360-degree air distribution solution for HVAC systems. Ideal for a variety of spaces, including warehouses, manufacturing plants, retail, fitness, and convention centers, the C-Series drop-down plenum diffuser provides facilities with directional control of their indoor airflow system in spaces where traditional ductwork is not an option.

When it comes to designing commercial HVAC and plumbing systems, engineers have to overcome a number of challenges. While everyone faces perennial budget and timeline issues, system efficiency is becoming a bigger concern every year.

Imagine a world where all HVAC equipment, (i.e chillers, variable frequency drives etc.), all BAS sensors, various components of the electrical systems (i.e electrical panels, meters, lighting fixtures etc.), and various components of all other infrastructure systems are connected to a shared, non-proprietary network that integrates the functionality of each system.

These days, everyone seems to want a smart building, but taking the desire for a smart building and turning it into a design is difficult to say the least.

The idea for this month’s topic was hatched during a retro-commissioning project, but it offers lessons to be applied to new construction commissioning.

Johnson Controls has released version 3.4 of its SMART Equipment Control Firmware. The new SMART equipment firmware incorporates a new feature known as Continuous Reset Single Zone Control™ (CRSZ Control). Unlike the typical Single Zone Variable Air Volume (VAV) system operation, company reps said the CRSZ Control provides precise control of space comfort while maximizing energy savings.

Greenheck says it has expanded its line of Dedicated Outdoor Air Systems (DOAS) for high percentage and 100 percent outside air. Pre-engineered rooftop ventilator models RV-110 and RVE-180 with energy recovery offer capacities up to 18,000 cfm, up to 70 tons of packaged cooling, and 1,200 mbh indirect gas-fired heating.

Honestly, the definition of open systems is the most confusing of the three types. Open protocols are pretty straight forward — they’re protocols that communicate with one another.
