Geothermal Design Software GEO® Hourly

Geothermal Design Software

◦ Patented Residential and Commercial Geothermal Design Software to Simplify your Effort and Improve Accuracy in ground loop design, energy cost analysis, hybrid design, and solar design. Each building zone has a unique hourly analysis integrated with the zone heat pump selection, operation, and energy cost. The detailed heat pump operation matching cuts the design complexity and design time and improves accuracy. An easy analytics optimization is presented in a chart that reflects operating cost vs. the ground loop design. You can now set design contingency based on realistic operating conditions. This can reduce your first cost.

◦ The 60 year old heat transfer theory has been applied as described in Industry guidelines and substantially expanded to include a separate 8760 hourly analysis for each zone.

◦ The heat pump equipment selection process for each building zone is quick and automatically sized based on the building design parameters.

◦ Each simulation performs a triple-8760 hourly heat pump analysis for each zone enabling a energy cost comparison and payout for different lengths in ground loops designs.

8760 Hourly Analysis

Design method - unique zone hourly analysis:

◦ GEO® Geothermal Design software has a built-in 8760 hourly generator that is fast and efficient enabling each ZONE to have a UNIQUE 8760 HOURLY ANALYSIS for the heat pump equipment in each zone environment. This is a hugh accuracy improvement where single heat pump performance curves are used.

Selects the proper size zone heat pumps:

◦ The heat pump selected from the library is corrected and properly sized to match the real zone environment.
◦ Each zone is processed separately using the heat pump selected for each individual zone based on the heat pump capacity type responding to the performance capability of the zone heat pump.
◦ Now you're not forced to only use a single heat pump for the entire building. Running in a fixed capacity condition.

Triple hourly analysis - lower the first cost:

◦ A new way to evaluate geothermal designs is easy to adopt, and can lower the first cost of geothermal projects. Each zone performs a triple-8760 hourly analysis based on three separate design parameters. Using the energy cost from this analysis a comparison is presented showing the payout for different lengths in ground loops designs.
◦ Intelligent Analysis transforms your insight for contingency and economic payback evaluation.

Hybrid Design Integrated:

◦ Hybrid operation is not an add-on optimization program, but is integrated into the original design method where 8760 hourly analysis and individual heat pump equipment are performed for each individual zone. Every geothermal heat pump design can elect to allow part of the ground heat exchanger to be offset by a fluid cooler, cooling tower, or boiler. Select the portion that you want directed to the hybrid and the ground borefield is designed along with the hybrid parameters.

Energy Model - Zones

◦ The Energy-Cost integrated in the application uses your Building Operation selections to apply the operating relationship of the heat pump type characteristics to the building thermal loads for the heat rejected to the ground or heat extracted from the ground. Heat Pump equipment models can be selected from many manufactures-brands for each of the 40 zones. GEO ®Hourly corrects the rated performance data to match the indoor building conditions specified in each zone. Each building zone is then analyzed separately for the cooling and heating loads on the coil, and GEO®Hourly geothermal design software determines how many heat pumps will meet the zone conditions, and calculates the operating cost of each zone.

Detailed heat pump operation

GEO®Hourly Geothermal Design Software takes load calculations through to equipment sizing. The 8760 hourly integration applies your detailed heat pump operation to the building usage for the Climate Site location you select. GEO®Hourly was created as a genuine simple design tool that is easy to use, extremely fast, and reliable.

Easy analysis optimization

◦ Optimizing the length of the in-ground heat exchanger is critical to the economics and performance of a Geothermal Heat Pump system. Reducing the length of the in-ground heat exchanger reduces the installed cost and yields a faster payback. GEO®Hourly geothermal design software provides optimization methods and comparisons that allows you to lower the cost of the in-ground heat exchanger, and match the heat pump equipment size to the building zone.

Auxiliary Electric Heat

◦ Auxiliary Electric Heat is only needed about 30 hours a year and often times can be much more economical than increasing the model size of the Geothermal Heat Pump and increasing the length of the ground loop.

Benchmark vs. Design

◦ Design comparisons present analytics that show you insights into the real cost that may not be obvious.

Hybrid Design

◦ The in-ground heat exchanger for heating and cooling designs are almost never the same length, so a Hybrid system using a cooling tower to replace some of the in-ground heat exchanger may be a good alternate design for some projects.

Climate Data Library

◦ Climate Sites from over 470 locations in the US and Canada have their own built-in library of 8760 hourly climatic data.

◦ Design conditions are from ASHRAE. ©2013 ASHRAE, Used with permission.

Building Types Library

◦ The building usage has a significant impact on the length of the in-ground heat exchanger and the operating cost to heat and cool a building. GEO®hourly geothermal design software has a complete library of about 45 building uses and an internal heat gain estimator for each building. The general category of building types are list below.
