We Need More Field Data for Ground Source Heat Pump Design Model
In October, HVAC&R industry stakeholders gathered for the 2023 Decarbonization Conference for the Built Environment in Washington, D.C., where thought leaders, consulting engineers, architects and others met to discuss the prospective, exciting opportunities in reducing the carbon footprint of buildings. This article highlights key takeaways from the meeting. Read more

November’s issue of ASHRAE Journal includes topics such as the application of a dual-temperature chilled water system, recent trends in environmental health and the life of David Crosthwait Jr., the first African American man to be inducted in the ASHRAE College of Fellows.

Healthy buildings: IAQ, industry standards, & demand-controlled ventilation
We will define what makes a building "healthy," investigate the various challenges faced by different users, introduce the importance of collecting, analyzing, and visualizing data to help organizations achieve their goals, and educate on the current industry standards for both ventilation rates (IAQ) and high-performance HVAC systems. Several examples will be given to help illustrate end-user use cases, engineering designs, and technologies that coming into the market. Finally, we will examine considerations during the construction process to increase the chances of operations inheriting a facility that will meet stakeholders’ IAQ and energy reduction goals.
