The effect of physical environment comfort on employees’ performance in office buildings: A case study of three public universities in Malaysia

Purpose – Maintaining a comfortable physical environment in the workplace is claimed to be vital as it will create a “healthier” building with optimum environmental conditions, which enable employees to be healthier and have a lower absenteeism rate, and hence be more productive. Thus, the purpose of this paper is to deal with the importance of physical environment comfort in the office workplace. Evaluation was made of the office workers’ performance that is mainly affected by levels of comfort in the office. Design/methodology/approach – Three selected case studies were evaluated based on aspects of employees’ comfort, perceived health and absenteeism rate, by considering the elements of physical comfort that consist of room temperature, relative humidity and luminance level. The selected case studies were the Department of Development and Estate Maintenance of three research universities in Malaysia. Field studies were carried out using hygrometers and lux meters in measuring the said elements as well as post-occupancy evaluation, which involved 30 respondents for each case (total 90 respondents), to determine their perception of comfort and its effect on their health and absenteeism rate. Data collected were analysed using Statistical Package for the Social Sciences. Findings – The results suggest that employees did not find luminance level uncomfortable, when compared with room temperature, thus proving that employees are more sensitive to room temperature comfort. Furthermore, when the room temperature comfort was low, significant correlations were found with health-related issues such as feeling “stuffy”, being easily tired and having difficulty concentrating. Originality/value – This paper investigates the relationship between employee performance and a comfortable workplace environment. It could be concluded that an uncomfortable environment in an office workplace leads to health-related issues as well as increasing the absenteeism rate. High levels of employee absenteeism lead to decreased employee productivity, therefore affecting their work performance.

Influences of key stakeholders’ involvement in maintenance management

Purpose Proper maintenance management ensures a long-term investment and provides a support function in business continuity to achieve organisational goal. However, inadequate involvement and participation of key stakeholders in maintenance management limit the continuous improvement of maintenance performance. Currently, there is a lack of studies about the influence of key stakeholders’ involvement in maintenance. Thus, the purpose of this paper is to deal with enhancement of maintenance management through the involvement of key stakeholders. Design/methodology/approach This research adopted a mixed method approach to determine the relationship between involvement of key stakeholders in maintenance management and maintenance effectiveness. The approach comprised of literature review, questionnaire survey and semi-structured interviews. Findings This research suggests a positive correlation between involvement of maintenance manager (MM), maintenance staff, organisation, user and maintenance service provider (SP) in improving the effectiveness of maintenance management. The logistic regression analysis indicated that the involvement of MM and SP are significant predictors of maintenance effectiveness. The research further identified that there was a lack of involvement of the user and SP in maintenance management. Originality/value The research demonstrated that all key stakeholders should value the important roles of their participation in maintenance management to ensure an optimum return on a long-term investment. To create the awareness for the involvement of key stakeholders in building maintenance, studies on the advantages of participating in building maintenance and the impacts of ignorant towards building maintenance can be beneficial to the industry.

The impact of IEQ on occupants’ satisfaction in Malaysian buildings

This paper focuses on the importance of occupant satisfaction with indoor environmental quality in buildings as well as the effect of indoor environmental quality towards occupants’ satisfaction. This research applied post-occupancy evaluation as a method to indicate the building occupants’ needs, their satisfaction and comfort level. The research is based on a case study approach whereby a questionnaire survey was conducted among 25 organizations involved in managing office buildings. A total of 115 questionnaires were returned for evaluation of occupants’ overall satisfaction from aspects of indoor environmental quality in these buildings and to determine the occupants’ satisfaction level within these buildings. The findings revealed that indoor environment factors that could contribute to occupants’ satisfaction consists of lighting, air quality and aesthetic perception. These classifications were made based on the factor analysis done with 22 attributes of the indoor environment. The majority of occupants are satisfied with their health conditions and do not face any serious health problems. However, occupants highlighted that some environmental conditions, health effects, air movement, ventilation and air freshness are important criteria for their satisfaction and comfort. This study provides insights into how occupants perceive their indoor environment and comfort, and identify problems that could arise in buildings.

Maintenance of high-rise residential buildings

Preventive maintenance is an effective maintenance strategy to ensure the constant and efficient usage of building systems and their components. The reactive-based maintenance as the main strategy in high-rise residential buildings is a concern as the maintenance output resulting from the strategy could not achieve the standard level of performance. The purpose of this paper is to identify the characteristics of preventive maintenance and establish the relationship with maintenance performance in high-rise residential buildings.,The characteristics of preventive maintenance and maintenance performance parameters were identified through the literature review. A quantitative approach was adopted, where a questionnaire was distributed to the maintenance personnel of high-rise residential buildings. Then, ranking analysis and correlation were conducted to produce findings that help to achieve the research objectives.,The research findings indicate that there are seven maintenance characteristics significantly correlated with maintenance performance indicators (maintenance costs deviation, time variance of maintenance work, customer service and downtime rate). It is recommended that these characteristics are considered during the execution of preventive maintenance as they have a significant effect on the maintenance performance.,The extensive literature suggests the relationship between the characteristics of preventive maintenance and maintenance performance, but is still questionable. Thus, this research investigates the relationship between preventive maintenance characteristic and maintenance performance for high-rise residential buildings in Malaysia. The findings of the research can act as a guide for maintenance personnel to optimise maintenance performance by focusing on the highlighted preventive maintenance characteristics.

A review of commercial waste recycling policy in Malaysia

Commercial business sectors have an ethical obligation to act responsibility towards the environment. Although Malaysia has developed a National Solid Waste Management Policy, the prioritisation of options for waste management is from reduction, reuse, recovery, treatment and finally to disposal. However, recycling is the most enforceable of the environmentally sound practices that a business can undertake. The recycling rate in Malaysia is only 11% whereas businesses in most European Union countries such as Germany and the UK appear to achieve much higher levels of recycling, more than 50%. Apparently, there is a gap between the policy framework for sustainable waste management in Malaysia and that of developed countries. This study reviews the solid waste management policy frameworks in both developed countries and developing countries. It is critical to understand Malaysias sustainable development in solid waste management to ensure that responsible disposal of resources that meet the overall sustainability of the business can be attained.
