    Prioritising optimal underutilised historical buildings for adaptive reuse: a performance-based MCDA framework validation in Auckland, New Zealand
    (5/07/2022) Aigwi IE; Nwadike AN; Le ATH; Rotimi FE; Sorrell T; Jafarzadeh R; Rotimi J
    Purpose: Currently trending as a practical approach to promote urban and seismic resilience, the adaptive reuse of historical buildings relies on expertise from various professional backgrounds ranging from conservation, urban planning, construction management, architecture, engineering to interior design. This paper explores the applicability of a performance-based multiple criteria decision assessment (MCDA) framework to prioritise underutilised historical buildings for adaptive reuse in Auckland, New Zealand while balancing the diverse interest of all relevant stakeholders. Design/methodology/approach: A focus group workshop was conducted for relevant adaptive stakeholders in Auckland, New Zealand, to test the applicability of the performance-based MCDA framework developed by Aigwi et al. (2020) and prioritise four underutilised historical building alternatives for adaptive reuse interventions in Auckland, New Zealand. Findings: Findings from this study revealed the significant potentials of the performance-based MCDA framework, both as an evidence-based measurement tool to prioritise underutilised earthquake-prone historical buildings in Auckland's central business district and as an effective decision-making strategy. Also, the framework allowed the inclusion of diverse stakeholders through the integration of collaborative rationality, ensuring consistency and transparency in the decision-making process. Originality/value: The successful validation of the existing performance-based MCDA framework in Auckland, New Zealand, using multiple historical building alternatives, further strengthens its preceding validation by Aigwi et al. (2019) using only two historical buildings in Whanganui, New Zealand. The findings provide a theoretical platform for urban planning researchers to advance performance-based planning for adaptive reuse to other locations and fields. There are also interesting implications for local councils, heritage agencies, architects, urban planners, policymakers, building owners and developers in Auckland, New Zealand, as a guide to improving their understandings of: (1) the intangible values of optimal historical buildings perceived by the community as worthy of protection through adaptive reuse; and (2) the targeted needs of communities in the new functions of an optimal alternative from a group of representative historical building alternatives.

    Proactive post-occupancy evaluation
    (Build Magazine, 2021-08-02) Rasheed E; Rotimi J; Vilasini N; Weerasinghe A
    A digital post-occupancy evaluation system for checking the operational performance of commercial buildings will be a useful tool as New Zealand faces the need to meet stringent carbon targets.

    The green office environment: New Zealand workers' perception of IEQ
    (Emerald, 29/12/2022) Rasheed E; Rotimi J
    Purpose: Achieving an appropriate indoor environment quality (IEQ) is crucial to a green office environment. Whilst much research has been carried out across the globe on the ideal IEQ for green offices, little is known about which indoor environment New Zealand office workers prefer and regard as most appropriate. This study investigated New Zealand office workers' preference for a green environment. Design/methodology/approach: Workers were conveniently selected for a questionnaire survey study from two major cities in the country – Wellington and Auckland. The perception of 149 workers was analysed and discussed based on the workers' demographics. The responses to each question were analysed based on the mean, standard deviation, frequency of responses and difference in opinion. Findings: The results showed that workers' preferences for an ideal IEQ in green work environments depend largely on demographics. New Zealand office workers prefer work environments to have more fresh air and rely on mixed-mode ventilation and lighting systems. Also New Zealand office workers like to have better acoustic quality with less distraction and background noise. Regarding temperature, workers prefer workspaces to be neither cooler nor warmer. Unique to New Zealand workers, the workers prefer to have some (not complete) individual control over the IEQ in offices. Research limitations/implications: This study was conducted in the summer season, which could have impacted the responses received. Also the sample size was limited to two major cities in the country. Further studies should be conducted in other regions and during different seasons. Practical implications: This study provides the opportunity for more studies in this area of research and highlights significant findings worthy of critical investigations. The results of this study benefit various stakeholders, such as facilities managers and workplace designers, and support proactive response approaches to achieving building occupants' preferences for an ideal work environment. Originality/value: This study is the first research in New Zealand to explore worker preferences of IEQ that is not limited to a particular building, expanding the body of knowledge on workers' perception of the ideal work environment in the country.
