Deep Boreholes in GSHP Systems: Pressure Considerations & Installation Practices

Factors such as space limitations are forcing engineers to utilize deep boreholes to meet design requirements for Ground Source Heat Pump (GSHP) systems.
In such cases, hydrostatic pressures must be considered to ensure successful installation can take place. This short course, led by expert Ryan Carda, P.E., focuses on the necessary calculations along with the recommended […]

Radiant Heating Case Studies: Ceiling Panels & Injection Piping

Expert instructor Dave Yates answers student questions with customer anecdotes on the Fundamentals of Radiant Heating discussion board
Student 1: I’ve seen two references in the course to “high temperature” ceiling panels needing to be at least 8 feet above the floor. Is this to prevent children from touching them, or is it to limit the heat in […]

HVAC Engineering: Chilled Floors + Humidity

On the Integrated HVAC Engineering discussion board, expert Robert Bean answers questions about chilled floors and humidity considerations and air mixing…
Student 1:  
Chilled floors seems like a great idea, and if you’re going to do a radiant system, you might as well consider cooling and heating.

The humidity, however, seems to be a big concern. Vapor barriers […]

NYC Sets Precedent for Requiring Geothermal Certifications

The New York City Council recently passed local law 0609-A-2015 stating that all new city buildings or city-owned buildings undergoing a HVAC retrofit must use geothermal if the ‘geothermal system has the lowest net present value of all alternatives considered.’ This legislation is a big deal for designers and installers of geothermal projects because it requires a minimum […]
