    The Perception of COVID-19 Pandemic Lockdown: An Exploratory Study of New Zealand Home Occupants
    (MDPI (Basel, Switzerland), 2025-10-23) Rasheed EO; Tamang I; Onyeizu-Rasheed E; Vishnu P; Mohsin Shahzad W
    The COVID-19 pandemic imposed unprecedented restrictions on movement and daily life, testing the resilience and adaptability of existing housing stock, as families worldwide were forced to adapt their homes into multifunctional environments. In New Zealand, where lockdowns were among the most stringent globally, homes rapidly transformed into workplaces, schools, gyms, and places of refuge. Little is known about how these adaptations affected the sustainability of homes and occupants’ well-being, particularly in the context of future crises. This study examined the economic, environmental, and psychosocial impact of the COVID-19 lockdown on New Zealand households. A questionnaire survey was conducted, and a quantitative analysis method was employed using survey data from 92 valid responses from New Zealand respondents who experienced lockdowns in various types of housing. To find important patterns and connections, descriptive and inferential statistical analyses were conducted. Findings revealed that economic factors had the strongest influence on respondents’ perceived experience during the COVID-19 lockdown, with households reporting increased electricity and water use but reduced fuel costs. Environmental factors were also significant, with respondents noting the importance of fresh air, sunlight, acoustic privacy, and more spacious rooms, alongside the critical need for a dedicated workspace. Psychosocial effects included higher distraction levels, monotony, and heightened concern for health. Group differences highlighted the influence of age and the number of bedrooms on the perceived experience of lockdown. This pilot work offers a New Zealand perspective on the intersection of the pandemic with the sustainability of homes. The practical implications of this study highlight the need for sustainable housing retrofits, hybrid work policies that support ergonomic and acoustically adequate home offices, and demographic-sensitive interventions to enhance resilience and occupant well-being in future crises.

    Global Solutions for Sustainable Heating, Ventilation, Air Conditioning, and Refrigeration Systems and Their Suitability to the New Zealand Market
    (MDPI (Basel, Switzerland), 2025-05) Harvey NA; Rasheed EO; Amores TRP; Molina JL
    This paper attempts to find alternative ways in which heating, ventilation, air conditioning and refrigeration systems can be made more energy efficient and sustainable at a global level. Eight technologies or solutions that either passively or supplementarily reduce the heating or cooling load required by a structure are detailed. These technologies or solutions were then presented to heating, ventilation, air conditioning and refrigeration industry professionals in New Zealand to determine their viability and further establish market readiness towards integrating new, innovative, and sustainable solutions in New Zealand. A literature review was conducted to establish the performance of the selected solutions and understand their operational principles and the efficiency they provided. Qualitative research and data collected via semi-structured interviews provided the data for assessing the viability of the selected technologies in the New Zealand market. Following a thematic and hybrid-thematic analysis of the data, the technologies were ranked, and suggestions were made to help improve innovation and energy efficiency in the heating, ventilation, air conditioning, and refrigeration industry in New Zealand. Of the technologies selected, airtightness, heat recovery ventilation retrofits, materials and design principles, and photovoltaic hot water heating were identified as the most viable. The New Zealand market was deemed not to be in a good position to adopt new or alternative solutions. The main issues affecting New Zealand’s market readiness to assimilate innovative and energy-efficient solutions are a lack of new technologies, poor standards of education throughout the industry, a lack of regulation, and a lack of government incentives.
