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 […]
“What is an Energy Model?”
In this brand new free course, P.E. and LEED Fellow Chris Schaffner explains.
Chris describes a variety of methods for modeling building energy consumption. He starts with simple energy estimating tools of increasing complexity and finally arrives at detailed energy simulations.
A few simple methods are described, and spreadsheets built to use these methods […]
Expert Instructor Ryan Carda discusses vertical boring systems, horizontal ground loops and Energy Recovery Ventilator ducting on the IGSHPA Certified GeoExchange Designer (CGD Plus) Training discussion board…
Student 1: Would you say that the addition costs associated with vertical boring are greater than the cost of extra piping necessary for a horizontal system?
Ryan Carda: To a point – HDPE pipe itself is […]
A Limited Study of Electrical Designs for Motors: Understanding the Basic Concepts
by Ken Lovorn
We just introduced ‘Electrical Design for Motors’, a 6 CEU course on designing electrical systems for various types of motors. In our 50 person sampling of the electrical industry, we found that some of the basic concepts from the National Electrical Code that were […]
Ryan Carda, P.E. is the author of the International Ground Source Heat Pump’s official design and installation guide. Carda’s Antifreeze Volume Calculator for Geothermal Loopfields free tool is used in his Entry Level Geothermal Professional Certificate Training.
Here’s what the tool looks like:
Uses: This calculator is used to quickly determine how much antifreeze will be needed to reach the target […]
