Heat recovery ventilators (HRVs) have been utilised in the design of new residential units in Kotzebue, Alaska. This project will provide 50 new residential units for US Public Health Service health care professionals who will be working in a new hospital in Kotzebue. Kotzebue is located just north of the Arctic Circle on the coast of the Arctic Ocean. The ASHRAE 99% design winter condition is -38degF. The prolonged and severe winter conditions warrant construction designed to limit infiltration to the minimum that current construction techniques will allow. Consequently, adequate ventilation can be best ensured by mechanical ventilation provisions. Individual HRVs are provided to ensure compliance with ASHRAE Standard 62-1989. The residential units are heated by a hydronic baseboard fin-tube system. The HRVs provide supply air to the occupiable areas and obtain the exhaust air from the kitchen and bathroom(s).
