ABOUT
Our philosophy is to develop fully integrated mechanical and technological systems.
LEAF provides services through any stage of a project - from feasibility studies to full design and construction services.
LEAF Engineers provides integrated mechanical, electrical, and plumbing engineering, safety and security, commissioning, and technology design services to create high-performance, cost effective environments that prioritize eco-friendly operations. Our engineers have expertise in all types of building systems including educational facilities, office and work environments, laboratories, athletic venues, and municipal and government facilities. Our experience spans master plans of a few thousand square-feet to over one million square-feet.
LEAF provides services through any stage of a project – from feasibility studies to full design and construction services. We design systems for new developments, and provide assessments and analysis for existing facilities. We also provide on-site and post occupancy services during construction administration, such as measurement verification and building commissioning.
The essence of integrated engineering design comes from the close collaboration of the project team.
Our philosophy is to develop fully integrated mechanical and technological systems through the application of specialist skill sets in a multi-disciplinary environment. The use of integrated teams foster close working relationships and encourages the resolution of individual problems as they arise. These techniques avoid potential conflicts and develop understanding among team members of the requirements of other disciplines and encourages the development of mutually compatible solutions.
The essence of integrated engineering design comes from the close collaboration of the project team. There is a high performance team behind each great building. Such teams are characterized not only by exceptional individuals, but by a deep understanding and respect for each other’s strengths. We strive to integrate elements where dual functionality can be attained. This provides reduced installation time, reduced costs, and a leading, energy-efficient automated facility.
We believe in the power of design, the strength of strategy, and the ability of technology to transform businesses and lives.
Too many buildings are not meeting design performance goals or life cycle savings. This often results in inefficient operations of the building on a day-to-day basis. LEAF utilizes proprietary tools as a conduit to help identify these failures and help close the gap.
LEAF’s energy performance consultants assist clients in exploring various financing options available, and help them navigate through the process to assure maximum benefit. Our design specialists provide comprehensive assessments to deliver energy-efficient solutions that have a positive impact on annual energy costs.
Life Cycle Analysis is implemented to determine project-level return on investment. When utilized, the ROI tool can:
- Analyze expected versus savings throughout the project life cycle
- Become a decision-aid for comparative benefit analysis
- Capture behavioral and consumption differences between various space types
- Benchmark various projects based on state, climate zone, certification type, etc.
