In the 1970s VAV (Variable Air Volume) systems replaced CAV (Constant Air Volume) systems. Concurrently, the 8-bit microprocessor with 4500 transistors was introduced. In the field of commercial HVAC systems, VAV systems became the first choice and were used as baselines for energy standards.

The ASHRAE Learning Institute (ALI) has added three new courses to the 23 offerings in its 2018 online instructor-led course schedule.

Titus has developed new virtual reality training called Titus VR.

Sustainable real estate developer, Scott Mazo, founder and managing partner of University Place Associates LLC (UPA) in Philadelphia, received the Center of Excellence Award from SEMCO LLC.

This month’s B2B will focus an existing campus administration building renovation.

Radiant HVAC — what is it? Heating is done in three ways in buildings — convection, conduction, and radiation. Heating and cooling with air is common in most building HVAC systems.

Titus has hired Nick Searle as its chief engineer and sales for chilled beams and underfloor systems.

When the City of Tallahassee and Leon County collaborated on a consolidated public safety complex to deal with local emergencies, the stakes were high and the need for robust yet adaptable HVAC was, too. Another collaboration within the design — chilled beams and pump technology — represented a key component of the mechanical system as it stands ready for severe swings in occupancy and weather alike.

In which CFD modeling lets us compare two possible design configurations for ventilation in a hospital patient room, yielding some similarities and perhaps surprising differences in what each configuration means for pathogen control and occupant comfort.

Cornell’s Bill and Melinda Gates Hall required a suitably thoughtful design process. After considerable analysis, an unusual strategy emerged, led by chilled beams and DOAS with key dehumidification elements.
