The Walters Art Museum

Baltimore, Maryland

A $24-Million Renovation of a Major Art Museum

Mueller Associates has provided comprehensive MEP engineering services to the Walters Art Museum for nearly 25 years. Work has included a multi-phase modernization of the museum that addressed system deficiencies in both the circa-1908 historic Palazzo building along Charles Street and its 1974 companion structure along Centre Street. The initial phase included detailed assessments of the systems within both buildings. The second phase encompassed a comprehensive renovation of the 1974 building, including construction of a new southern entrance atrium and a conservation laboratory, as well as renovation of the lower level and mechanical/electrical systems in the 1908 building to accommodate a new museum store and art handling and photography studios. 

Energy-efficient systems remedied serious deficiencies in climate control, highlighted by a conversion to variable air volume, installation of a new condenser water-free cooling system, more efficient equipment, and improved control systems. The work also included a pre-action sprinkler system, an FM-200 fire protection system for art storage, an early warning fire detection and alarm system, lighting and control systems, and a new security system.

Additional projects have included renovations to approximately 6,000 square feet within the circa-1850 Hackerman House and Carriage House structures to accommodate semi-permanent exhibit space. These upgrades included modifications to air devices, sprinkler heads, lighting fixtures, and receptacles; and replacement of the humidifiers serving the air handling units.

Recent renovation efforts have included a study and design for comprehensive upgrades to the MEP systems in the Hackerman House, as well as a first-floor renovation to the 100 West Centre Street building to accommodate the temporary relocation of Hackerman House personnel. The MEP systems within the 19,300-square-foot One West Mount Vernon Place building have also been updated as part of a building-wide renovation.

Additional upgrades for the museum include a cooling tower replacement in the 1974 building, parking lot improvements, CELP application assistance for chiller replacements, a chiller building analysis, underground duct repair, replacement of metals storage HVAC systems, and a number of other improvements. Mueller also conducted an HVAC systems assessment and provided recommendations to support the museum’s Environmental Management Master Plan.
