Speaking Events
“When a question comes up about sustainability, Brenna is always my very first call.
She was excited about sustainability long before it became a business buzzword and, in many ways, it was Brenna’s passion that introduced energy efficiency and sustainability concepts – many of which we take for granted today – to the commercial real estate industry. Brenna was instrumental in creating BOMA International’s Energy Efficiency Program (BEEP) (more than 15 years ago). That program revolutionized how commercial real estate owners and managers operate their buildings, and it helped to move “green” programs into the mainstream of building operations best practices. Brenna also championed the adoption of Energy Star throughout the commercial real estate industry, and she remains an ardent supporter of Energy Star programs.
One of the things that differentiate Brenna from other consultants is her considerable commercial real estate management experience and her executive leadership expertise. This unique background allows her to develop compelling business cases for sustainability and energy efficiency programs – and ultimately find the “green” solution that is right for each of her clients.
Brenna knows “everyone,” and she is an expert at getting the right people around a table to solve the problem at hand – whether the solution is for a client, a colleague, BOMA International, or the commercial real estate industry as a whole. She is a strategic thinker, a consensus builder, and an active mentor to so many building owners and managers. Without exception, I highly recommend Brenna as a sustainability expert and a thought leader in the commercial real estate field.”
“A very engaging presentation from Brenna Walraven that highlighted the importance of a strategic approach to the business case for sustainability and high performance operations. Very informative and insightful!”
“For those of us lucky enough to have heard you present before, I believe it was a real treat for BOMA Southern Region Conference attendees to hear and see you. You’re such a natural speaker and always deliver pertinent and timely information. We’ve heard really positive feedback about your presentation.”
