Description
Summary:This paper characterizes ventilation in residential suiteslocated in ll buildings were between six and thirty-two stories tall andwere built between 1990 and 1995. The key findings from field performancetests of these buildings were: 1. Corridor supply airflows usually didnot meet design flows.2. Makeup air paths for suite exhaust were notproperly designed.3. Suite access door leakage was highly variable andusually did not meet smoke control requirements.4. Airflow from thecorridor through the suite access door leakage appeared to be the primaryventilation air supply for suites.5. Suites were usually well-ventilated,but some were marginally- or under-ventilated.6. Poor pressure controloften allowed transfer air from one suite to another. Inter-suitetransfer air fractions ranged from 0 to 45 percent, with an average of 19percent. In summary, this work showed suite ventilation can be highlyinfluenced by corridor supply flows, by the treatment of corridor accessdoors, and by transfer airflows. As a result, suite ventilation at anygiven time in current mid- and high-rise residential buildings is verydifficult to predict. To ensure suite ventilation performs as intendedunder all operating conditions, the building industry needs to addressthe identified problems through improved ventilation design, operation,and maintenance practices.
