​Sustainable Building Design

Creating a Sustainable Future

Our LEED-certified project portfolio began with Florida's first LEED-certified project in 2003 and today consists of projects around the world, including numerous LEED firsts, in both Florida and across America.

In May 2009 TLC formalized our commitment to sustainable design by accepting the 2030 Challenge, one of the first MEP firms nationwide to do so. We are living our commitment daily through ongoing changes in our work processes, business practices and by making a significant commitment to education and training, both internally and externally. Click here for our annual Sustainability Action Plan. TLC's Sustainability Committee involves representatives from all of TLC's business units to keep our engineering designs, skill sets and professional credentials at a competitive edge.

As an advocate of sustainable design, TLC has extensive proven experience in various sustainability building rating systems, including LEED, Green Globes, Living Building Challenge and more.

Our services range from rating system administration through deep green consulting and all the steps in between:

  • Facilitating an initial, concept-phase sustainable design charrette with the design, construction and owner team. The charrette serves as the team's opportunity to confirm the owner's green goals and develop the sustainability plan for the project. During the charrette, TLC guides the team through a review of appropriate sustainable building design goals, strategies and rating systems.
  • If the project is pursuing certification, credit guardians are assigned for each credit and prerequisite, along with an action item list to qualify for the desired credit. Credit guardians are responsible for gathering the information required for credit documentation. TLC reviews and submits the documentation, allowing the credit guardian to retain responsibility for the technical accuracy of the information.
  • Conducting periodic review meetings to maintain the project timeline and target.
  • Coaching and mentoring construction and project team members during the gathering, cataloging and extensive documentation of local and regional materials, recycled content, construction waste diversion and low-emitting finish materials.

TLC will also facilitate your project certification when serving as your MEP and/or structural engineer by documenting credits related to mechanical, electrical and structural building systems, including indoor air quality, water conservation, measurement and verification, controls, thermal comfort design, as well as the traditional energy use optimization credits including:

  • Participation in sustainability design charrettes and meetings.
  • Calculations associated with assigned credits.
  • Investigation, analysis and documentation of assigned credits through online reporting systems.
  • Completion of templates and uploading of supporting documentation for all assigned credits.


“TLC’s culture of learning, client service and high-performance engineering is why I’ve stayed at TLC for more than 20 years.”
