4-Step Guide to Designing Geothermal Systems

The first part to understanding any aspect of the geothermal industry, whether it be marketing, sales, design or installation is to understand how the technology works and it is designed. By understanding the design process, even if you are never going to do design yourself, you will better understand how the technology is sold, will be confident when speaking to customers, will know what information needs to be collected on a site visit, and which leads have greater potential then others. If you plan on working on the installation side, understanding design will give you the knowledge to understand the different parts of an installation and what those may cost.
If you’re new to the geothermal heat pump industry, read the Geothermal 101 Reading list. It has free tools and articles on geothermal design and installation and sales and marketing best practices. Here are some other free resources:

How You Can Use Geothermal To Gain LEED Certification

Here is an excerpt from a white paper I just published on how and where a ground source heat pump can be utilized to gain LEED certification.

By now, nearly everyone has at least heard of LEED but not many understand what it means to be LEED-certified or how best to earn certification. Developed by the US Green Building Council (USGBC), LEED stands for “Leadership in Energy and Environmental Design”. Simply put, LEED is a grading system for sustainable building design and construction.

The goal of the program is to encourage the construction of buildings that use less energy, water and natural resources in order to minimize the impact of a structure on the local environment during construction and throughout its useful life. Needless to say, geothermal heating and cooling systems can go a long way to supporting all of these goals.

The LEED rating system works by requiring a minimum level of performance through prerequisites organized under eight different categories. Once you are able to meet the minimum performance requirements in each category, any improvements above and beyond are rewarded through a points system. The eight categories are:
