I2SL Workshop: Evaluate the Savings and Return on Investment (ROI) of Laboratory Energy Savings Strategies

Offered in support of the Smart Lab Accelerator Partnership Program

Under a cooperative agreement with the U.S. Department of Energy, I2SL is also offering this workshop in support of the Smart Lab Accelerator Partners. Partners or those interested in becoming partners should see staff at the conference registration table.

Analyzing a laboratory's HVAC energy consumption and comparing different energy efficiency strategies is often quite difficult. The many unique aspects of these systems and their controls do not lend themselves to conventional, commercial, or widely available energy analysis programs. As a result, engineers are left to work around these programs with pre- and post-processing or else come up with a simple custom spreadsheet analysis for each situation. Unfortunately, these analyses often do not have sufficient detail and accuracy regarding the actual laboratory HVAC system and controls to provide accurate enough comparative analysis, particularly for sustainable projects with multiple energy conservation strategies.

To address these challenges, a comprehensive custom laboratory energy analysis and ROI spreadsheet tool has been developed that evaluates the combined savings of multiple laboratory energy efficiency measures such as chilled beams, various types of heat recovery, demand-based controls, variable air volume fume hood controls, evaporative cooling, and other approaches using typical meteorological year 3 temperature and humidity data for 1,700 cities around the world. In addition to energy savings, the analysis tool can model the impact on the first cost of various strategies due to both the cost impact of the equipment itself plus potential changes to the HVAC capacity requirements resulting from these systems.

This user-friendly tool can track multiple levels of detail based on the quality of the utilized assumptions. The tool can also be used to see the environmental impact of energy savings approaches in terms of metric tons of carbon dioxide saved, among other metrics. The tool has been validated by multiple utilities and is currently being used for energy incentive rebate calculations.

This workshop will include a prerequisite overview followed by a detailed, hands-on training with this spreadsheet-based tool, as well as a complimentary license for the use and basic support of the tool.

Attendance is limited for this workshop.

Equipment Requirements

Attendees must bring a laptop that is equipped with Microsoft Excel 2007-SP2, Excel 2010, Excel 2013, or Excel 2016 to the workshop. Older versions such as Excel 2003 are not sufficient. Two attendees from an organization may work together on problems and share one computer.


Gordon Sharp, the chairman of Aircuity, Inc., has more than 25 years of wide-ranging entrepreneurial experience and holds more than 25 U.S. patents in the fields of energy efficiency and laboratory controls. As founder, former president, and chief executive officer of Phoenix Controls, Mr. Sharp led the development of this world leader in laboratory airflow controls that was acquired by Honeywell in 1998. In 2000, Mr. Sharp founded Aircuity, a smart airside energy efficiency company that was spun out of Honeywell.

Mr. Sharp is a graduate of the Massachusetts Institute of Technology with a bachelor's degree and master's degree in electrical engineering. Mr. Sharp is a member of the Board of Directors of I2SL, the nonprofit foundation that hosts the I2SL Annual Conference and formerly cosponsored the Labs21 Annual Conference, a member of the ANSI/AIHA Z9.5 Laboratory Ventilation Committee, and a member of the ASHRAE SSPC standard 170 Ventilation of Health Care Facilities committee.
