DEAL MIDDLE SCHOOL ADDITION
DC Department of General Services | Washington, DC
Alice Deal Middle School is an award-winning public school in the heart of Washington, D.C., instructing around 1,500 students annually across 6th, 7th, and 8th grades. They educate their students through rigorous academics and meaningful experiences.
To increase the capacity of Deal Middle School due to projected enrollment, the addition at Deal Middle School building will be roughly 21,700 square feet, adding 14 new capacity generating classrooms. Additionally, there will be space added for a student cafeteria, science lab, and academic support areas. The addition will bring Deal in line with the DCPS educational specifications.
The addition will address Americans with Disabilities Act (ADA) requirements. Learning, instruction, and support technology will be brought up to cutting edge standards and capacity. Classrooms with appropriate square footage will be created from the original open floor plan concept to create an adequate 21st century learning environment and meet the DCPS educational specification standards.
High Performance Design
The design team is tracking an EUI (Energy Use Intensity) of 23.6 for the new building, which is aligned with what one typically sees for NZE school buildings. Some of the strategies that we used in order to get to this EUI include:
Envelope and Massing: We designed a compact surface area to volume ratio so that not much heat can escape, and exceeded insulation levels and air tightness recommendation for our climate zone.
Glazing: We kept the percentage within ASHRAE recommendations for our climate zone, and optimized the location of glazing for daylighting.
Water-Based Systems for Heating and Cooling: We used a water-source system for heating and cooling, which is 26 times more efficient than air at temperature control.
Lighting Design: We took an approach to lighting design for the project that used fixtures that provided the most efficient number of watts per square foot.
