The Herman & Walter Samuelson Children's Hospital, Sinai Hospital of Baltimore

Patients and visitors to The Children’s Hospital Expansion project at Sinai Hospital in Baltimore City are greeted by the hospital’s marine design theme, and entertained by a live broadcast feed from the National Aquarium in Baltimore. The project involved both renovation and new construction to tie the new Children's Hospital Expansion into the Mt. Pleasant building and the adjacent Blaustein Building.

A new third floor level was constructed above the existing Mt. Pleasant building. This new floor aligns with the existing third floor of the adjacent Blaustein Building which was fully renovated to accommodate the new Children's Diagnostic Center (CDC) program. The addition and renovations provided for a new 34,500 square foot inpatient pediatrics unit with 26 patient rooms, including four negative pressure isolation rooms with anterooms, and nine protective oncology patient isolation rooms. The renovated area of the existing third floor of the Blaustein Building provides support space for the Children’s Hospital including the CDC program on the south wing, new procedure rooms, and a PACU.

The mechanical and electrical systems serving the hospital were part of an integrated design approach to meet the Baltimore City Green Building Standards. A new energy-efficient central air handling system utilizing the central plant utilities was required to serve the new addition. Energy modeling was performed in accordance with the Baltimore City Green Building Standards to demonstrate a minimum 10% energy savings above the ASHRAE minimum standard. Additionally, LED technology was utilized for the lighting systems throughout the project.
