Facilities Energy Management & Sustainability

Energy efficiency is TEESI’s core business. Since its inception, TEESI has been involved in conducting facilities site surveys, which identify energy & utility cost reduction retrofit opportunities such as HVAC, lighting, piping/plumbing, controls systems, and building envelope improvements. TEESI conducts detailed engineering calculations for proposed efficiency improvements measures, develops cost estimates, develops baseline energy use consumption for facilities, prioritizes projects based on need and payback, and prepares detailed reports, which can be used as planning documents for implementation.

Here are a sampling of the specific ways we can help you plan for and operate a more efficient facility.

    • Preliminary Energy Assessments (PEA)
    • Utility Assessment Report / Detailed Energy Assessments (DEA) /Investment Grade Audits (IGA)
    • Water & Wastewater Treatment Plant (WWTP) Energy Assessments
    • Design for Energy & Water Conservation Measures
    • Renewable Energy Technologies Evaluation & Design
    • Design for Utility / Energy Cost Reduction Measures
    • Energy Management Plan Development
    • Integrated Energy and Sustainability Plans Development
    • Development of Measurement & Verification Plans
    • State & Federal Energy Program Evaluation
    • 3rd Party Review for Energy Performance Contract Projects

New Construction and Renovation MEP Design

Because of TEESI’s involvement in planning, design and construction management activities for schools, community colleges, universities, hospitals, commercial/industrial, cities, state and local government entities across Texas, the firm is very familiar with various required codes, design criteria and laws governing public works construction.

Whether we are working on a new chilling plant, learning environment, or office space, we strive to understand institutional standards, existing infrastructure and life cycle of required systems.

As an experienced engineering firm holding Minority and HUB status, TEESI is a sought after partner for many institutions and architects.

New Construction, Retro & Re-commissioning

Commissioning is the process of ensuring that a building performs according to its design intent and the needs of its owners and occupants. It is a quality-oriented process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets defined objectives and criteria.

Commissioning accomplishes higher energy efficiency, environmental health, and occupant safety and improves indoor air quality by making sure the building components are working correctly and that the plans are implemented with the greatest efficiency.

To ensure TEESI provides the highest value in their commissioning services, the firm holds the following certifications.

  • ACG-Certified Commissioning Authority (CxA)
  • Building Commissioning Association (BCA) Service Provider® Firm

Continuous Commissioning®

Continuous Commissioning® (CC®) is an ongoing process to resolve operating problems, improve comfort, and optimize energy use for existing buildings.

TEESI, as a Licensed CC Partner has access to the tools, research and expertise that make the Continuous Commissioning process effective. This select group of Engineers and Building Professionals have the necessary skills and training to quickly identify the best improvement opportunities that can be implemented with the least cost while producing the greatest impact.
