We specialize in educational, small commercial, mixed-use, multifamily and single-family residential projects from California to Wyoming, beyond and in between. Working with people who want the best for their buildings, on projects that excite and challenge our team, enables us to deliver unparalleled results.

We have high standards and believe that "good enough" is not good enough. We strive to push the envelope on every project--whether it's a net-zero Passive House office building or modest residential remodel that just wants to be the best it can with limited resources. No matter how ambitious your goals, we'll help educate you and your team about best building practices and make sense of what can be a confusing myriad of options and approaches.

Principal and Founder Katy Hollbacher, P.E., is a licensed Civil Engineer, Certified Passive House Consultant, LEED AP, Certified GreenPoint Rater, and Certified Energy Plans Examiner with fifteen years experience in the architecture/engineering/construction and green building industries. She is currently involved in numerous Passive House projects, which can achieve space heating and cooling savings up to 90% compared to conventionally designed projects. Beyond Efficiency takes a whole-systems, integrated approach to design and engineering challenges. Building projects typically proceed in a linear fashion and lack adequate collaboration with other parties on the design—often resulting in change orders, budget overruns, resource and energy waste, and dissatisfied clients. Beyond Efficiency will help integrate effective communication throughout all phases of your project to help ensure that social, environmental, and economic goals are achieved.
