Energy Services


The scope of our energy audits are consistent with ASHRAE Level III standards, and includes compilation of field data, engineering analysis, life-cycle costing, and energy modeling to calculate the project’s anticipated savings as accurately as possible. Taking into account such variables as building design, envelope, orientation, weather, schedules, controls, district systems, and energy-using systems, energy modeling allows Entegrity to prioritize energy efficiency measures by first cost, rate of return, and environmental impact. Entegrity gives the upfront engineering support to define energy and operational savings by measure. With the support of our Preconstruction Team, we quantify project costs in the IGA and develop plans for implementation.

An IGA includes many activities, but in general there are three (3) main phases of the process:

  1. Inventory
  2. Solutions
  3. Reporting

Building Modeling

A building energy model is a simulation based on building design, envelope, orientation, weather, schedules, controls, and energy-using systems to project comparative energy consumption and costs. Using building modeling, Entegrity can prioritize energy efficiency measures by first cost, rate of return, and environmental impact. Our team of Building Modelers utilize the most advanced modeling software including IES Virtual Environment, Trane Trace, and Energy Plus.

Building modeling provides the most value early in the design process, when design decisions such as orientation, floor plan, and HVAC systems have yet to be determined. Analysis can include:

  • Energy Conservation Measures
  • Net Zero Energy
  • Sustainability Rating Systems
  • Load Checks
  • Shading/Orientation
  • Daylighting
  • Access to Views
  • Hygrothermal Movement
  • Life-cycle Cost
  • Utility Incentive Potential
  • Code Compliance
  • Measurement and Verification


The Measurement & Verification process includes establishing the potential of a project’s efficiency measures to save energy and then verifies that the expected results associated with these upgrades are achieved. Entegrity can evaluate with specificity where and how energy is used and provide information that reassures our customers get the results they expect from investing in energy efficiency.

Our process utilizes the industry standard protocol of the IPMVP (International Performance M & V Protocol). Our M & V solutions are customized based on project needs and include metering hardware and an easy to use software platform.

M & V Basic Process:

  • Determine IPMVP Option and Set Goals
  • Gather Baseline Energy Data and Record
  • Design Energy Saving Program
  • Prepare Measurement and Verification Plan
  • Issue Design Specifications for M&V Plan
  • Commission M&V equipment
  • Gather energy use data as defined in the M&V Plan
  • Compute and Report Savings
