ABSTRACT

The New Zealand Building Code mandates maintaining habitable spaces and bathrooms in elderly homes at a minimum internal temperature of 16°C with adequate ventilation. This study assesses the thermal wintertime performance of 40 subsidized apartments designed for older residents within a 7-Homestar certified building in Auckland. The building performs well, falling below the 16°C threshold only 5 per cent of the time across all units. However, inconsistencies exist, particularly on the top floor (Level 3), which is colder than other levels. This reveals a potential flaw in the typology approach of green certifications, like Homestar, where certifying a single dwelling within an apartment building does not guarantee uniform thermal performance across all units.

摘要

新西兰建筑规范要求将养老院的居住空间和浴室保持在最低内部温度 16°C，并保持足够的通风。本研究评估了奥克兰一栋 7-Homestar 认证建筑内 40 套专为老年居民设计的补贴公寓的冬季热性能。该建筑表现良好，所有单元中只有 5% 的时间温度低于 16°C 阈值。然而，存在不一致的情况，特别是在顶层（第 3 层），它比其他楼层更冷。这揭示了绿色认证类型学方法的潜在缺陷，例如 Homestar，对公寓楼内的单个住宅进行认证并不能保证所有单元的热性能一致。
