Lambeth Field Apartments complex is comprised of 25 buildings with 174 student apartments. The apartments were conditioned using package terminal air conditioning units (PTACs), which were the only source of outside air and had chronic moisture infiltration and humidity issues. The University needed to update these systems for improved living conditions.
As prime consultant on this term contract project, 2RW’s services included a field survey of existing systems and conditions and the subsequent feasibility study summarizing system replacement options and recommendations. We then provided MEP engineering and construction administration for a dedicated outside air system (DOAS) with new package terminal heat pumps (PTHP) and a direct digital control (DDC) building automation system (BAS) connected to the central campus building management system for monitoring and automated alerts.
The project was constructed over two summers while the apartments were vacant and 2RW expedited the design which enabled HVAC equipment to be ordered for the entire complex at one time, saving money for the University. The early lead time on the equipment maximized the summer construction schedule, allowing installation to be completed prior to the students returning for both Fall semesters.
The new HVAC system required minimal renovation and successfully conceals infrastructure. It provides positive pressurization of the buildings with space-neutral dehumidified air, improves ventilation and controls humidity; providing healthier living environments and making the residences more energy efficient and comfortable. The PTHP units provide individual climate control for bedrooms and common spaces in the residences.
