Kevin Gilleran is Founder and Principal of GEM. Active in the field over 30 years, his passion for green building and energy efficiency grew out of curiosity and a solutions-oriented approach to balancing the needs of people with the environment. His collaborative approach to green building and energy efficiency solutions is executed through a process-driven approach to guide a project from planning through completion. Kevin encourages teamwork and ongoing communication to deliver economically viable green solutions to meet client project goals.

Under his leadership, GEM has successfully impacted thousands of affordable housing, residential and commercial projects. His comprehensive approach to quantitative analysis informs his thorough approach to bring the latest knowledge to the field. Providing ongoing communication with a projects multi-party team encourages cost-effective design and construction delivery processes. Serving as an objective third-party for a design and construction team he serves as a neutral party to lead support for facilitating a client’s strategic vision through fruition.

He also believes that everyone should have access to adequate housing. Housing programs at the local, state and federal levels have not adequately addressed the current housing shortfall. In California, sustainability and various energy efficiency programs, such as LEED certification or integration of other green features can increase scoring to make a project more competitive. He is experienced in competitive and non-competitive tax credit projects, successfully collaborating with project teams to deliver value-driven solutions to meet a client’s project goals. He brings his extensive experience to the field to provide a wide array of green building and energy efficiency service offerings to support a client’s project goals by collaborating with design and construction teams to optimally integrate green features.

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
