Phased renovation and addition at Dranesville Elementary School to modernize building systems and expand instructional space. MEP/FP systems were designed to improve indoor environmental quality, energy performance, and system reliability while supporting classrooms, shared learning spaces, and an expanded library and media center in an occupied school environment.
2RW provided MEP/FP engineering for the phased renovation and addition, coordinating new and upgraded building systems to support classrooms, shared learning spaces, administrative areas, and the expanded library and media center. The design approach balanced modernization with constructability, allowing the school to remain occupied while systems were replaced and integrated in phases.
Mechanical systems were designed to improve ventilation, thermal comfort, and humidity control across both renovated and new spaces, supporting healthier learning environments and more consistent conditions throughout the building. Electrical systems were upgraded to accommodate modern educational technology, improved lighting quality, and reliable power distribution, while supporting future flexibility as classroom needs evolve. Plumbing systems were designed with an emphasis on durability and water efficiency, supporting daily school operations with minimal maintenance demands. Fire protection systems were fully integrated into the renovation and addition, meeting current life-safety requirements and providing comprehensive coverage throughout all occupied areas.
Energy modeling informed system selection and coordination, helping align the design with Fairfax County Public Schools’ performance expectations and long-term operational goals.
The completed project delivers improved energy performance and indoor environmental quality informed by energy modeling and County performance standards. Upgraded building systems reduce overall energy demand while supporting reliable operation, consistent comfort, and appropriate ventilation for an active elementary school. The design prioritizes long-term efficiency and durability, providing Fairfax County Public Schools with a high-performing facility that supports daily learning and operations with reduced energy and maintenance demands.
Energy modeling at the CD phase indicated a site energy use intensity (EUI) of 43.27 kBtu/ft²/yr, a 34.3% reduction in energy use compared to ASHRAE 90.1-2010 baseline systems.
