Building occupants are important factor in giving information on indoor conditions such as comfort, productivity, building performance and occupants ́ health. Even that, being their appraisal mainly based on subjective judgments, it is difficult to set up a standard and objective method for this purpose. The present work aimed to describe, analyze and compare the most common tests on this topic, in order to highlight critical, failings and strengths.

POE is important to evaluate comfort level and satisfaction of building occupants because it indicates their productivity, health, and wellbeing. It is absolutely necessary to ensure building occupants are comfortable and satisfied about buildings’ indoor environmental quality (IEQ). Productivity may be interrupted due to building occupants’ discomfort, which affect their work performance. This study presents the how comfort and satisfaction affects the occupants’ productivity in conventional-designed buildings. Five office buildings located in University of Malaya were selected as the case studies. 278 questionnaires feedbacks found to be useful to form a database on the IEQ. Data obtained were analyzed using SPSS software. The findings shows that majority of the respondents in conventional-designed building were slightly comfortable and satisfied about their IEQ comfort level which were indoor air quality, thermal, lighting, and noise comforts. Although, the design of conventional buildings did not taking into account on sustainability designing, it still functionally well and provided comfort which leads to increasing of employees productivity. The associative test showed significant correlation between illness symptom and IEQ components. Admin buildings had more noticeable illness symptoms in contrast with Faculty buildings. It could be concluded that building occupants’ productivity were least affected by the conventional-design building.

Post Occupancy Evaluation

Green Rating Certification is one of the important mechanism developed in last few decades worldwide to achieve sustainability in Built Environment life cycle. The early generations of Green Rated Built Environment from India have occupied for several years now. Therefore, it has become inevitable to assess whether these Built Environment are living up to expectations in their objective terms. Post Occupancy Evaluation is a process of systematic monitoring of Building's performance with predefined parameters and objectives after it is occupied for few years. Present research focuses on assessment of Green Rated Built Environment on the basis of performance parameters. Indoor Environmental Quality (IEQ) and Energy Efficiency are two performance parameters identified for current research. Seven Green Rated Institutional/office projects have been selected for Post Occupancy Evaluation. Indian Green Building Council (IGBC) has rated three projects and Green Rating for Integrated Habitat Assessment (GRIHA) has rated remaining four buildings. All seven projects are located in warm and humid climatic zone of India. Questionnaire Survey, on site measurement of Indoor Environmental Quality parameters and Energy consumption records are selected as a tool to measure performance of Green rated project.

Occupant Satisfaction

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.

Research has shown a strong correlation between the performance and health of young students and teachers, and the indoor environmental quality (IEQ) of their schools. A post occupancy evaluation (POE) of a school’s IEQ can help stakeholders understand the current conditions of the building and their impact on occupant wellbeing and productivity. It can also provide pathways for building performance upgrades and resource allocation for school administrations. However, current research on POE in schools frequently omits the contexts of young students during evaluations. Furthermore, there is limited research on guidelines for performing POE and measurements in school facilities. This study adopted the National Environmental Assessment Toolkit (NEAT) and tailored qualitative methods to evaluate eight schools over an eight-year period. The methodology was refined throughout the study to develop a protocol for robust investigation of IEQ conditions in schools. The NEAT was developed by Carnegie Mellon University’s Centre for Building Performance and Diagnostics for measuring the IEQ of office buildings. The paper addresses the challenges that may occur during POE and measurements (POE+M) and the differences between POE+M for offices and schools. It also determines how the POE+M process can be efficiently implemented to include all primary stakeholders in order to improve data collection for IEQ and energy efficiency analysis.

Evaluation Survey

Post-occupancy evaluations are common tools used to periodically assess Indoor Environmental Quality (IEQ) in tertiary buildings. Although the large amount of data collected from surveys contain valuable information, the influence of building characteristics on IEQ considering the different uses of the rooms and different types of occupants is rarely considered in the evaluation. This study presents an analysis of the association between building characteristics and IEQ in different building rooms (classrooms and offices) and different occupants (students and lecturers) using a post occupancy evaluation survey to 1013 occupants in 26 higher educational buildings in Spain under a Mediterranean climate. This research demonstrated that building characteristics influence IEQ perceptions of the different rooms in tertiary education buildings. The possibility of controlling the lighting, shadows or heating, ventilation air or conditioning (HVAC) systems are the most influential factors when analyzing IEQ. The findings of this research are of interest to facility managers aiming at implementing energy efficiency measures based on user-centric satisfaction or developing maintenance plans focused on IEQ enhancement.
