17. Presentation Outline Building Overview Existing conditions System Evaluation Proposed Redesign Mechanical Depth Electrical Breadth Conclusion In conclusion on my research of ground source heat pump or hybrid geothermal for DE Hospice, I find that hybrid geothermal is a great choice for a more green design with a lower first cost. If ground source heat pumps can be afforded it would be better to choice them in the long run. With only saving $53,000 a year, it would only take just over six year of annual savings to make up for the $319,180 in equipment cost. 17
