What Leaf Engineers does
Leaf Engineers is a privately held MEP/T (Mechanical, Electrical, Plumbing, and Technology) engineering consulting firm headquartered in Houston, Texas, founded in 2002 (originally as PBK Engineers, rebranded to LEAF Engineers in 2020). The firm provides mechanical, electrical, plumbing, fire protection, technology systems, commissioning, energy modeling, sustainable design, photovoltaics, and security/AV consulting services to K-12 school districts, higher education institutions, government agencies, and commercial clients. LEAF operates as part of the PBK family of companies alongside related engineering brands (DIG Engineers, EdgeLand Group, Kubala Engineers, BEAM Pro), with deep architectural partnerships with PBK and its higher education, K-12, and California divisions.
The firm employs 110-120 professionals across 18 office locations spanning seven states (Texas, California, Georgia, Florida, Washington, with additional presence in Oklahoma, Illinois, Michigan, and Louisiana), having completed over 3,000 projects for 250+ clients over 23 years. Notable client engagements include multi-school district MEP programs for Katy ISD, Killeen ISD, Corpus Christi ISD, Dublin USD, Fresno USD, and Clovis USD; campus-wide MEP and security infrastructure for University of Houston, Texas A&M, UC Berkeley, and Sam Houston State University; a 90,000 sq ft IRS call center; and commercial retro-commissioning for Hilton and HP Hood. Differentiated capabilities include proprietary energy performance and ROI benchmarking tools, AABC Commissioning Group recognition, and demonstrated delivery on net-zero energy design (e.g., Stockton Junior High with 1-megawatt solar) and LEED/CHPS-certified projects.
LEAF generates revenue through project-based professional engineering services contracts, typically engaged either directly by institutional end clients (school districts, universities, government agencies) or via architecture firm partners. Pricing is quote-based and negotiated per project scope, with no publicly disclosed pricing. The go-to-market model is enterprise field sales driven by reputation, repeat client relationships, and project portfolio referrals rather than self-serve or product-led channels. Marketing emphasis is on thought leadership content, whitepapers (e.g., Building Well for K-12 and Higher Education), conference publications, and project case studies.
