Sam serves as a Senior Project Manager at GEM. With over 25 years of experience his background in engineering and architecture provide the foundation for his skilled approach to green building and energy efficiency programs. He has served as the architectural project manager for major school projects providing planning and construction oversight of multi-disciplinary professional teams. He has provided retrofits to new public middle and elementary schools.

Leading more than a dozen Municipal Climate Action Plans in Northern California, he targeted emission reductions more than 15% for each jurisdiction. This was sponsored by PG&E to provide comprehensive energy consumption documentation, energy cost and greenhouse gas analysis of historical utility data for Sonoma County municipalities. His work showed the progress that each jurisdiction made towards its stated greenhouse gas reduction goal. It also provided a financial analysis of energy efficiency projects to leverage funding opportunities for medium and long term energy efficiency projects.

Sam believes in improving his community and the world around him. He has formally served on a number of formal public service offices, including as a Sebastopol City Council member, mayor of Sebastopol and several associated local and regional committees.

Collaboration during social distancing

April 23, 2020

Dear friends, clients, colleagues and collaborators,

Our team hopes that you are all staying safe and well during this time of crisis.

The situation is fast changing, and Gilleran Energy Management, Inc. is taking every precaution to protect the health and safety of our clients and our staff. We are committed to providing continued service to our clients while abiding by the recommendations or orders from the CDC, WHO and other local governing agencies. We have spent the last month taking proactive and precautionary steps to keep everyone safe while still moving our projects forward efficiently. Things are not business as usual, but we are happy to report that we are now set up to work remotely from the safety of our homes.

There have been some delays and/or inconveniences while we made this transition, we apologize for that. We thank you for your patience and understanding as we continue to adjust to the new “normal”. Most importantly we appreciate your business and choosing to work with our committed group of energy and green building consultants to achieve your goals.

We will continue to monitor the fluid situation as changes continue to occur on a daily basis. Counties in the Bay Area have further restricted work, as of April 1, on construction sites unless they are considered an essential service i.e. affordable housing, medical or government related projects. Our team will continue to shelter in place and will correspond remotely whenever possible. We have created and adapted some industry policies that allow remote site visits via live video and audio as well as the use of photo-documentation. As things change, we will continue to update you.

Please feel free to contact Kevin with any questions or concerns.

Warm regards,

Kevin, Sam, Kim Beltran, Michael, Samantha, Ian, Kim Carpico and Christie
