About this project
Kroeschell oversaw five building additions totaling 8,000 SF; as well as 4,500 SF of non-mechanical space converted into mechanical rooms. These conversions included all facets of construction; electrical, plumbing, HVAC, sheet metal, fire alarm, sprinkler piping and extension of natural gas utility piping to provide new gas meters for all buildings.
A significant component of Kroeschell’s bid package was the proposed “Betterment Package.” Kroeschell suggested two types of betterments.
- With the first, Kroeschell identified steam boiler plants that they believed could be converted to hot water boilers instead: hot water boilers were selected with efficiencies up to 96% while steam boiler efficiencies are only 80%. We located 14 buildings that were eligible for this betterment and saved the Navy $1,150,000.
- In the second, Kroeschell offered a hybrid solution. The design called for expensive high-efficiency condensing boilers in all buildings. We proposed the installation of both high-efficiency condensing boilers as well as lower efficiency but more economical noncondensing boilers. We chose this solution because a condensing boiler at full load is not condensing anymore, and therefore, there is no benefit. This saved the Navy 11.7% on boiler equipment costs or $415,000.
- By year three, 95% of the new boilers were operational and the base was already reporting about 25% less energy consumption as they had seen in previous years.
- Kroeschell’s two betterment packages saved the Navy $1,570,000.
The Naval Station Great Lakes has recognized nearly $9,000,000 a year in energy savings with the Betterment Packages, emissions reduction savings and federal rebates.
