    Enhancing the Energy Performance of Historic Buildings Using Heritage Building Information Modelling: A Case Study
    (MDPI (Basel, Switzerland), 2025-07-02) Kakouei M; Sutrisna M; Rasheed E; Feng Z; Caggiano A; Kamari A
    Heritage building conservation plays a special role in addressing modern sustainability challenges by preserving the cultural identity, retrofitting, restoring, and renovating these structures to improve energy performance, which is crucial for revitalisation. This research aims to use Heritage Building Information Modelling (HBIM) to increase energy efficiency and environmental sustainability in historic buildings. Retrofitting heritage buildings presents unique challenges and opportunities to simultaneously reduce energy consumption and carbon emissions while maintaining historical integrity. Traditional approaches are often insufficient to meet heritage structures’ energy needs. Modern technologies such as information building modelling and energy simulations can offer solutions. HBIM is a vigorous digital framework that facilitates interdisciplinary collaboration and offers detailed insights into building restoration and energy modelling. HBIM supports the integration of thermal and energy efficiency measures while maintaining the authenticity of heritage architecture by creating a comprehensive database. Using a case study heritage building, this research demonstrates how retrofitting the different aspects of heritage buildings can improve energy performance. Evaluating the preservation of heritage buildings’ cultural and architectural values and the effectiveness of using HBIM to model energy performance offers a viable framework for sustainable retrofitting of heritage buildings.

    Does the Number of Occupants in an Office Influence Individual Perceptions of Comfort and Productivity?-New Evidence from 5000 Office Workers
    (MDPI (Basel, Switzerland), 25/03/2019) Rasheed E; Khoshbakht M; Baird G
    Purpose—The purpose of this article is to present evidence of occupants’ perception of their work environment in five different office types (Solo, Duo, 2–4, 5–8 and 8Plus offices). The study examined the influence of the number of office occupants on individual perception of indoor environment quality (IEQ) in office environments. Design/methodology/approach—A dataset of 5000 respondents in 67 commercial and institutional office buildings was analysed using IBM SPSS v23. The dataset contained user response on the BUS Methodology questionnaire that is designed to retrieve occupants’ perception of their work environments. Analysis of Variance (ANOVA) and multiple regression analysis were conducted to calculate the impact of the office environment on occupants’ perception of comfort and productivity. Findings - This study showed that occupants in Solo and Duo offices perceived higher satisfaction with their environment (except for temperature in summer), better health and productivity; and more control over the office environment than those in 5–8 and 8Plus offices. Occupants in 8Plus offices were most satisfied with the temperature in summer. It was also noted that the IEQ factors that predicted comfort were observed to not predict productivity. Noise was the only IEQ factor that had predictive power for both comfort and productivity in all the office spaces. Originality/value—This article provides intriguing findings on occupants’ perception of various types of office environment that contributes significantly to the debate on open-plan versus cellular office environments.

    Fuel Poverty Awareness: A Preliminary Study of New Zealand Tenants
    Rasheed E; Holliday L; Mohanty N
    Fuel poverty is an issue that has been documented to affect many low-income households in New Zealand. Many studies have shown the effects of fuel poverty to include health and mortality issues during winter periods in the country. To eradicate fuel poverty, sufficient information should be provided to not only decision makers but those directly affected – low-income earners. This study is aimed at investigating the level of awareness of low-income earners to fuel poverty and its effect on their health and comfort. A two-stage survey was carried out on tenants in low-income tenants within Auckland city. This survey involved a questionnaire survey of tenants and physical observation of tenants’ households in Auckland City, New Zealand. The results show that there is insufficient awareness of fuel poverty amongst tenants. Also, the majority (80%) do not seek advice on fuel poverty and the associated effects. The results further showed that there is still evidence of fuel poverty in these households. The implication of this study calls for more efforts to be made by the appropriate authorities to inform the public, in particular, those affected, about fuel poverty. This pilot study was carried out on a small population of low-income earners. More studies are required across the country for the results to be generalised.

    Easy Steps to ArchiCAD by EAI: A teaching manual
    (School of Built Environment, Massey University, 1/05/2019) Rasheed E
    Prepared for High School and first year students in Architecture and Construction-related programmes Easy Steps to ArchiCAD is designed for students in construction-related programmes. It provides an easier means of learning how to draft designs using ArchiCAD software. This teaching manual helps you learn to use various tools in ArchiCAD while designing a simple residential building. The focus is on providing a good understanding of the major steps required to design a building in ArchiCAD. It illustrates basic information in ArchiCAD commonly used to design buildings. This manual simulates a real architectural project, in detail, and is perfect for everyone who wants easier and more explained steps to the use of ArchiCAD for building designs.
