The paper analyses the indoor environment in two modern intelligent buildings located in Poland. Measurements of air and globe temperatures, relative humidity and carbon dioxide concentration in 117 rooms carried out in the space of 1.5 years were presented. Thermal comfort of the occupants has been investigated using a questionnaire survey. Based on 1369 questionnaires, thermal sensation, acceptability and preference votes were analysed in view of their interdependency as well as their dependency on operative temperature, which proved to be very strong. It has been found that the respondents did not completely rate thermal comfort and indoor environment quality as very high, although the overwhelming sensations were positive. Apart from the operation of heating, ventilation and air conditioning (HVAC) systems, this might have also been the cause of individual human factors, such as body mass index, as tested in the study, or the finding that people were generally in favour of a warmer environment. Moreover, thermal environment proved to be the most important element for ensuring the well-being of the occupants.

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.

Health And Well Being

Indoor environments have a large impact on health and well-being, so it is important to understand what makes them healthy and sustainable. There is substantial knowledge on individual factors and their effects, though understanding how factors interact and what role occupants play in these interactions (both causative and receptive) is lacking. We aimed to: (i) explore interactions between factors and potential risks if these are not considered from holistic perspective; and (ii) identify components needed to advance research on indoor environments. The paper is based on collaboration between researchers from disciplines covering technical, behavioural, and medical perspectives. Outcomes were identified through literature reviews, discussions and workshops with invited experts and representatives from various stakeholder groups. Four themes emerged and were discussed with an emphasis on occupant health: (a) the bio-psycho-social aspects of health; (b) interaction between occupants, buildings and indoor environment; (c) climate change and its impact on indoor environment quality, thermal comfort and health; and (d) energy efficiency measures and indoor environment. To advance the relevant research, the indoor environment must be considered a dynamic and complex system with multiple interactions. This calls for a transdisciplinary and holistic approach and effective collaboration with various stakeholders.

The Impact

The green building certification system has long-lasting benefits by improving building efficiency and sustainability. The ultimate goal of such classification is to promote the preservation of the global environment as well as the occupants’ well-being and their health. In this paper, we present examples of buildings that have been designed and built in Poland and have been certified with BREEAM, LEED and WELL. Our study investigates human factors in certification systems and examines the WELL Building Standard as a supplement to other green systems, which will probably be the most popular in the future. The green building movement should prioritize pro-human factors and the associated environmental beliefs to improve indoor environment quality for users’ needs. We present this matter on the example of the Polish office space market, providing statistics and analyzing the architecture of six certified office buildings from Warsaw, Poznań and Wrocław. They are a representative sample of buildings designed following the certification regime. It was demonstrated how this aids in improving work comfort, enhances the program of office spaces and the organization of service spaces within buildings, which increases the rank of this architecture and positively affects the urban environment.

Ventilation Fan

Strengthening indoor ventilation is an important measure to improve air quality. In transitional season between spring and summer, a university classroom in Jinan city was selected as the research object. Mechanical air supply is adopted to solve the problem of insufficient fresh air or excessive carbon dioxide concentration in the classroom. CO2 concentration and air change rates are compared in natural ventilation and mechanical classrooms. The experiment shows that the indoor CO2 concentration of mechanical ventilation classroom is relatively low. Under natural ventilation, mechanical ventilation and mixed ventilation, the average air change rates were 1.05 h-1, 1.83 h-1 and 2.7 h-1, respectively. According to the statistics analysis of the questionnaire, 72.84% of the students hope to install the mechanical ventilation in the classroom.

Indoor Environment Quality

This study reviews some published literatures to survey the recent research on indoor environment quality and building energy consumption. The indoor environment quality is categorized and defined as different indices and variables. The building energy consumption can be determined by ventilation rates, thermal comfort, adaptive thermal comfort, neutral temperature, set-point temperature, indoor air quality, air velocity, and non-occupied hours. Various climates or regions such as subtropical climates in Hong Kong, Italy, three climatic zones in Greece, hot and dry climates in Africa, hot and humid climate in Thailand, are contained. The building types include office buildings, commercial buildings and school buildings, and the data can be obtained from a simulation model or the field database. It can be concluded that the indoor environment quality has a significant influence on the building energy consumption, and a validated thermal model is be a practical tool to investigate the effect of the indoor environmental parameters.

Indoor Environment Quality

Energy saving in buildings is one of the most important research directions in the building sector. Energy saving solutions should not lead to decreased indoor environment quality. Because of the increased number of summer heat waves, cooling systems are widely used to assure thermal comfort in buildings. In this paper, ceiling cooling and wall cooling systems were tested and compared from the thermal comfort point of view using 24 subjects (12 women and 12 men). The cooling ceiling and wall surface and the supply/return temperatures were similar. Analysing the obtained subjective answers, no significant differences were obtained on average or by gender. However, significant differences were obtained between the subjective answers and the calculated PMV values. Furthermore, the occupant’s reaction was different after switching off the ventilation and cooling systems.

Comfort Criteria

This study reviews some published literatures on the benchmarking and ranking guidelines, tools and comparison of buildings. Energy performance, Indoor air quality and thermal comfort can be covered for the rating tools for buildings. Further, the energy performance can also be calculated by the other parameters related to the room thermal properties. A rating system to benchmark buildings can employ several parameters including indoor environment quality, clothing volume, predicted mean vote, operative temperature, and thermal energy consumption. It can be concluded that the indoor air quality or thermal comfort can be used to evaluate buildings due to their influence on the occupant satisfaction and job performance. Also, building benchmarking or rating will be various because Different comfort criteria may lead to different comfort temperature.
