Rader Engineering

This project consists of 15 buildings and 244 units total. Units are Studios, 1-bedroom, 2-bedroom and 3-bedroom units. The project is a HUD project (U.S. Department of Housing and Urban Development) and so the budget was extremely tight and meeting this budget was of great importance. The mechanical system design was tailored to meet this budget, meet code as well as the needs of the occupants. Each building has a two-boiler central heating plant which serves two domestic hot water heaters, as well as hydronic baseboard within the units and common areas. Each boiler consists of 2 heating stages thus there are four stages of heat per building, contributing to better levels of energy efficiency. Because all the buildings face south, the project team elected to provide through-the-wall air conditioners for summer comfort. Other systems include corridor ventilation, bath exhaust and dryer exhaust.
