Friday, May 20th | 11:00 AM - 1:00 PM | Zoom


As the need to decarbonize the buildings that we live and work in becomes critical, heat pumps (HPs) are going to play a central role in this effort.  In this session we will discuss design considerations for HP installation for both space and domestic water heating.  The presenters will go into detail about these considerations for both Multi and Single family buildings and commercial building applications including existing building retrofits using case studies of local projects showcasing the designs being discussed


  • Discuss why heat pump technology is vital to decarbonize buildings 

  • Discuss different heat pump technologies and how different technologies are suited to different building types.

  • Identify energy efficiency opportunities and other benefits of heat pumps

  • Discuss Heat Pump design considerations including the following:

    • Location

    • Sizing

    • Types

    • Building loads

    • Electrical panel limitations

  • Presenters will discuss local case studies that showcase the design considerations above

Calina Ferarro, P.E., LEED AP

Calina is a principal and mechanical engineer with Integral Group leading their San Diego office. She has over a decade of sustainable engineering experience in Canada and the US across a broad range of building sectors, including commercial, higher education, life science, and healthcare. Calina takes a holistic approach to design, striving to create healthy, enjoyable, and environmentally responsible spaces while minimizing the size & complexity of the mechanical systems. Calina has a Mechanical Engineering degree from McGill University. She is a recipient of Consulting Specifying Engineer Magazine’s 40 Under 40 award in 2015 and Plumbing & Mechanical Engineer Magazine’s Mechanical Engineer of the Year award in 2018.


Josie Gaillard

Josie Gaillard is a retired product manager whose work at SunPower in the early 2000’s helped launch the company from a small start-up to a multinational solar manufacturer with a downstream installation business, a first of its kind in the solar business. She currently works full-time on climate change, which some days means navigating tight crawlspaces to assess opportunities for electrification and other days means working on a web-based tool she is developing to simplify electrification of existing buildings. She is deeply interested in what motivates people to act, enjoys solving complex problems with others and places high value on the life lessons she has gained raising a child. She served as a commissioner on Menlo Park’s Environmental Quality Commission where she co-wrote the city’s Climate Action Plan. Josie has a BA from Princeton and an MBA from Berkeley’s Haas School of Business.

Thank you to the SDG&E Energy Innovation Center for supporting this event.
