Building Research and Information: the international journal of research, development and demonstration. 52. 6. (pp. 680-692).0961-3218https://mro.massey.ac.nz/handle/10179/71610The 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.(c) 2023 The Author/sCC BY-NC-ND 4.0https://creativecommons.org/licenses/by-nc-nd/4.0/Indoor Environment Qualitythermal comfortgreen buildingunder heatingJournal article10.1080/09613218.2023.22564341466-4321journal-article680-692
