ASHRE Level-3 Energy Audit, Building Commissioning
We served the St. Louis Cardinals Baseball Club for 5 years as the Energy Manager and Solar-PV Developer for Busch Stadium. Our work with the Cardinals started with a comprehensive ASHRAE Level-3 energy audit and simulation model and a full-building commissioning.
This work led to the development of a comprehensive listing of potential energy-related projects in the stadium. We then worked with the various stakeholders in the organization to prioritize these hundreds of energy opportunities, and then dedicate a capital budget to achievement of the many project goals with outstanding results.
Over the course of our term as Busch Stadium’s Energy Manager, the energy team was able to reduce energy consumption in the stadium by over 20%, reduce base load by 25%, and realize water savings of many millions of gallons a year. The efficiency savings actually were 100 times a greater impact than the energy produced by the stadium solar-PV system.
Some of the greatest impact to energy performance was achieved through defining how the stadium is shut down after a game, after a home stand, and at the end of the season—then optimizing those procedures. We have found that this approach delivers good results with a wide variety of commercial and industrial clients seeking improved energy performance.
Project Challenges: The greatest challenge working with the Cardinals is the schedule. Since the Cardinals end up in the post-season MLB Playoffs almost every year, the months available for intrusive upgrades are limited to November through March. Those also are the most difficult months to work in St Louis, since that region can have a severe winter climate.
Then, through the rest of the year, the game schedule makes scheduling work more challenging, since the game side of the stadium may be vacant for days at a time, and then fully occupied every day for a week or longer. All this occurs while the business offices operate on a conventional business schedule.
The stadium owners are businessmen and women with typical financial performance objectives. It also was key in the energy program to meet or exceed those financial expectations for the ongoing energy program. The team focused on identifying and accomplishing the measures that had acceptable financial performance, as well as achieving other non-financial goals.
