The study presented in this paper focuses on the subjective opinions of occupants of multistory residential buildings by examining the relationship between occupants’ satisfaction and indoor environment quality, and analysing the effect the problems experienced with noise level may have on general satisfaction and the perceived acoustic quality. The analysis is based on data collected through surveys addressed to adults living in green and conventional buildings. The results show that occupants are very satisfied with their apartments, and subjectively rated acoustic quality received very high scores. The responses indicate that noise from neighbours has been experienced relatively seldom by occupants; however, the analysis shows that it is the factor that has the strongest effect on satisfaction with acoustic quality. We have found that the environmental profile of a building has a significant effect on general satisfaction expressed by occupants; however, this effect has not been confirmed for acoustic quality.

The Relationship

The research focused on the analysis of the interaction of the individual components of the system operationally efficient building – indoor environment quality – user has been conducted since 2014 in the Czech Republic by a team of College of Banking (BIVŠ) employees. The purpose of the research is the evaluation of advantages and disadvantages of operationally efficient buildings by their owners, users or facility managers. One of the most monitored research parameters is the rating of indoor environment quality and its influence in physical and psychological fitness and work performance of the building users. Next, there are also other relationships which are examined – as the importance of the indoor environment quality with regards to other building's parameters, its influence of the estate market value and the users' willingness to participate on the creation and keeping of indoor environment quality. The interpretation of gathered data proved a significant difference of the individual users' demands in relation to their individual preferences. This fact is necessary to respect while design and managing the operationally efficient buildings.

Acoustic Conditions

Recently, many facilities have completed new laboratories that may be used to assess various measures of Indoor Environment Quality (IEQ) in office spaces. Also recently, a new standard, ISO 3382-3, was released for assessing the effects of speech on IEQ in open plan offices. The aim of this report is to assess one room of the IEQ lab using the ISO 3382-3 standard. It is expected that the data gained will be of help to researchers using the facility in the future.

To control the spread of coronavirus disease (COVID-19), Saudi Arabia’s government imposed a strict lockdown during March–July 2020. As a result, the public was confined to indoors, and most of their daily activities were happening in their indoor places, which might have resulted in lower indoor environment quality. Polycyclic aromatic hydrocarbons (PAHs) were analyzed in household dust (n = 40) collected from different residential districts of Jeddah, Saudi Arabia, during the lockdown period. PAHs’ levels were two folds higher than the previously reported PAHs in indoor dust from this region. We detected low molecular weight (LMW) with two to four aromatic ring PAHs in all the samples with a significant contribution from Phenanthrene (Phe), present at an average concentration of 1590 ng/g of dust. Although high molecular weight (HMW) (5–6 aromatic ring) PAHs were detected at lower concentrations than LMW PAHs, however, they contributed >90% in the carcinogenic index of PAHs. The estimated daily intake (EDI) of specific PAHs was above the reference dose (RfD) for young children in high-end exposure and the calculated Incremental Lifetime Cancer Risk (ILCR) was >1.00 × 10−4 for both Saudi adults and young children. The study highlighted that indoor pollution has increased significantly during lockdown due to the increased indoor activities and inversely affect human health. This study also warrants to conduct more studies involving different chemicals to understand the indoor environment quality during strict lockdown conditions.

This study examines the differences between two environmental assessment methods for the K-12 education sector: the United States Green Building Council's (USGBC) LEED Schools Version 3.0 and the British Research Establishment's (BRE) BREEAM Education issue 2.0. Credit requirements are compared side-by-side and against recommendations from researchers in areas such as acoustics, lighting and indoor environment quality. Strengths in the two schemes and areas for improvement are highlighted, with acknowledgement that each scheme offers components and techniques from which the other could benefit.

This study aimed at evaluating the indoor environment conditions of the private hostels in Ifite Awka Anambra state with a view to establishing its quality and impacts on students dwelling on these hostels in the study area. Being a survey research, the study was affected by the use of questionnaire, literature searches and direct observations. Accordingly, a total of 311 questionnaires were administered while 258 questionnaires which represent 83% were returned and found useful. The study found that IEQ parameters of hostels in study area are: Indoor air quality was poor due to inadequate ventilation of rooms; thermal comfort of rooms was found to be warm; indoor light quality was found good and the acoustics comfort and noise slightly good and to some extent poor. Therefore, the study recommended that during the design and construction of buildings, IEQ parameters should be considered, so as to obtain a quality indoor environment.
