“…Intensive airing of the rooms caused a rapid drop in CO2 levels. Increasing the number of air exchanges in rooms will reduce the level of CO2 pollution [22]. During the study the value of outside carbon dioxide fluctuated in the range from 438 ppm to 456 ppm.…”

Realization and exploitation of buildings involves in European Union about 40% of total energy consumption [1]. One of the elements of rationalization of energy consumption in buildings are the undertakings related with thermal modernization of buildings. The actions related with reducing the energy intensity of buildings are not always correlated with improvement of microclimate conditions in the rooms. Errors in the implementation of the energy efficiency program led to the phenomenon of sick building syndrome. The paper presents the results of the research conducted in a few educational buildings before and after thermal modernization. The research includes energy consumption for the heating of building and selected parameters of the interior microclimate. This analysis was carried out to evaluate the influence of energy saving activities on microclimate interior conditions. It was found that in many cases commonly used gravitational ventilation is not able to ensure the proper conditions of the interior microclimate, and the concentrations of carbon dioxide recorded in the tested rooms exceeded the applicable standards.

“…Most people spend about 90-95% indoors rather than outdoors (Vilčeková et al, 2017) where children spend 7 to 11 hours per weekday at school (Pegas et al, 2010). Pupils spending most of their daytime in the classroom are exposed to health problems which are frequently triggered by inadequate ventilation (Salleh, Kamaruzzaman, & Mahyuddin, 2013).…”

“…Studies on air quality in terms of CO₂ concentration level in educational buildings have been conducted in other countries. Some of them reported that the CO₂ concentration level exceeds 1000 ppm (Lee & Chang, 2014;Mainka & Zajusz-zubek, 2015;Vilčeková, Kapalo, Meciarova, Burdova, & Imreczeova, 2017;Persson, Wang, & Hagberg, 2018). However, it is known that the indoor CO₂ concentration level should not exceeds 1000 ppm as compliance with ASHRAE and ICOP (ICOP, 2010;Salleh, Kamaruzzaman, Riley, Zawawi, & Sulaiman, 2015).…”

Private preschools in Malaysia have shown significant inclination throughout years however recent studies for Indoor Air Quality (IAQ) targeting more on school rather than preschool building. It is contradicting as preschool students are susceptible to unhealthy environment as they often spend time indoors plus their metabolism level is different than an adult. Therefore, this study emphasises IAQ in the classroom of two refurbished preschool buildings. Besides, their correlation with the space of classroom and number of children are also being determined. The case study is conducted in Penang Island based on the type of building (double storey house) with natural ventilation system. Parameter such as carbon dioxide (CO₂) is measured and analysed to compare with the existing standard and regulation which are i) Industrial Code of Practice (ICOP), ii) American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) and iii) Uniform Building by Law (UBBL). Findings indicate the maximum concentration of indoor CO₂ reached more than 1000 ppm for classroom that exceeds the 15 person/classroom limit, which did not comply to ASHRAE and ICOP standards. The excessive of CO₂ caused from several factors such as openings of door and window, space of the classroom and the number of pupils in the classroom.

“…Many studies are focused on indoor environmental quality in educational buildings, i.a. (Dorizas et al, 2015, Haverinen-Shaughnessy, 2015, Mihaia and Iordacheb, 2016, Turunen et al, 2014, Indoor air quality, 2012, Vilcekova et al, 2017. The subject of the conducted research was the assessment of the indoor environmental quality based on selected parameters and its impact on thermal comfort and safety of use of rooms associated with the appearance of symptoms of a sick building syndrome among building users.…”

Safety of use of the buildings refers i.a. to ensuring appropriate hygienic and sanitary conditions and also health conditions. According to the EU Directive on the energy performance of buildings, there is a need to define the conditions for the classification of objects in terms of indoor microclimate requirements. Evaluating the quality of the interior environment in buildings and specifying the requirements of people staying in them, first of all the values of thermal microclimate parameters and air quality should be taken into account. Long-term influence of disadvantageous of environmental conditions may cause or exacerbate many symptoms associated with abnormal functioning of the organism and lead to the weakness or illness. This phenomenon is called sick building syndrome, and the symptoms of the syndrome such as eyes and respiratory tract irritation, malaise, dizziness and headache or fatigue are linked to time spent in the building. The article presents the results of research on the condition of the interior environment in educational buildings, identifies factors affecting the formation of environmental conditions in the rooms and shows the influence of the interiors environment in buildings on the human body. The relationships between the basic parameters of the interior microclimate and the state of feeling satisfaction with the environmental conditions that surrounds the human are tracked. It was found that in many cases commonly used gravitational ventilation is not able to ensure the proper conditions of the interior microclimate, and the concentrations of carbon dioxide recorded in the tested rooms exceeded the applicable standards. Keywords: interior microclimate, air quality, hygienic and sanitary conditions, sick building syndrome, safety of use of the buildings.
