The Fort Smallwood Facilities Directorate is one of 12 administrative buildings in the Anne Arundel County Public School (AACPS) District located in Maryland. The district implemented a number of energy conservation measures (ECMs) including lighting upgrades, energy management equipment, and water-efficient fixtures. The project achieved an annual energy savings of 18 percent and annual cost savings of over $33,000.
Anne Arundel County Public Schools is the fifth-largest public-school district in Maryland with 125 schools, serving a student population of 82,000 and a building portfolio of 13.8 million square feet.
The measures installed in the facility included a conversion to T-8 lighting and occupancy sensors, in addition to upgraded water efficiency fixtures.
Below is a list of the various savings measures, costs incurred and estimated savings expected upon the project’s conclusion.
Savings Measure | Cost | Savings Achieved | Notes |
T-8 lighting retrofit and occupancy sensors throughout the building | $110, 219 | Over $88,000 in utility rebates and approx. 8% annual savings on energy bills | Project completed summer 2013. Annual simple payback was just over 1 year. |
Water efficiency fixtures in men’s bathroom | $5,000
| Average monthly savings of $30 (17%) | Includes sinks, faucets, flush-valves, associated parts (materials and labor). Project completed winter of 2015-16. |
In addition to the ECMs, the district also installed a 1.4 MW ground-mounted solar farm consisting of nearly 4,000 panels which was funded as part of a district power purchase agreement at zero cost to the district. AACPS will purchase the generated electricity at a discounted rate of $0.055 per kWh. The system is expected to produce almost 2,000 MWh of electricity, returning a savings of nearly $1.8 million over the 20-year life of the agreement.
A 2016 report identified Anne Arundel County as one of the top five Maryland counties with the most potential for benefit from a solar project – including the creation of more than 100 jobs and cost savings of approximately $1 million over a 30-year period.
