One of the big decisions when constructing a new building is how to heat and cool it. If you want a solution that is environmentally friendly and can lower your energy costs, you should consider installing a hybrid geothermal system. This type of system reduces upfront capital costs, emits fewer greenhouse gases and lowers energy costs.
Using the Greensleeves’ Solutions Tool, we modeled a hypothetical 74,000 ft² school in Memphis, TN. In this model, the school could incur an initial capital cost of $1.16M, and have annual energy expenditures of $91k, using a conventional HVAC system.
That same school could incur an initial capital cost of $1.78M, and have annual energy expenditures of $62k, using a traditional geothermal system. This system has additional capital costs but reduces the energy costs by approximately 32% annually.
If this same school used a hybrid geothermal system, the model shows that the initial capital cost could be $1.48M and the annual energy expenditures would be $53k.
In this scenario, a hybrid geothermal system uses approximately 42% less energy than a conventional system, and the installation cost is $300k less than a traditional geothermal system. Running the lifecycle cost analysis in this Solutions Tool, a hybrid geothermal system has a $2.6M savings when compared to a conventional system, creating a 7.7-year payback.
Every new construction project should consider a hybrid geothermal system as cost effective alternative to conventional HVAC systems. Save your money, while saving our planet.
