Leach Wallace provided mechanical and electrical design consulting and computer building energy modeling to meet minimum LEED Silver design requirements for the 35,000 gsf renovation and addition of Ward and West Residence Halls at Towson University.
The project involved renovations to the Ward and West Halls, which included demolition of the entire interiors while existing exterior walls remained in place. In addition, a new three story addition connected the building together. Furthermore, West Hall received a new one story addition and all new interior fitout and MEP systems were installed.
Leach Wallace worked with Towson University to analyze the yearly utility cost of Ward and West Halls to accurately evaluate HVAC options and develop a LEED energy model to meet LEED Silver requirements. This energy model included modifications to the building envelope, an energy and lighting model to participate in BGE energy savings programs, and LEED enhanced commission support and post construction activities. The Building is on target to meet LEED Gold,
A combination of Chilled beam and hybrid fan powered terminal units were used to achieve 25% energy savings and fit the tight floor to floor heights, which made a conventional ducted HVAC system not feasible. Equipment was ceiling mounted to not crowd the window area and allow for more efficient building layout and lower noise levels from building systems.
The building utilized dedicated outdoor air systems with total energy recovery wheels. The entire building required only 10,000 cfm of air handling unit capacity. The remaining heating and cooling was provided by the chilled beams and hybrid terminal units. Campus chilled water and steam were utilized.
