Evaluation of Indoor Environment Conditions in Offices Located in Buildings With Large Glazed Areas

Abstract

Abstract. The field study was carried out during the heating season in two Lithuanian office buildings with large glazed areas. The methodology was prepared for evaluating indoor microclimate parameters while using objective and subjective evaluation. The results show that the average temperature in all tested offices was in the range of optimal zones, but in some offices the average temperature was not in compliance with the recommended temperature for offices. During the subjective evaluation, respondents working in these offices identified complains because of too high temperatures, stuffy air and irritation in eyes. The average relative humidity measured in all tested offices was not in compliance with the optimal requirements. Such SBS symptoms as irritation in eyes, cough and dry skin of the hands were identified as the most frequent symptoms in the second tested building. Main indoor microclimate problems arising in buildings with large glazed areas were related to overheating indoor spaces because of the direct sun and improper ventilation.

Thermal Comfort and HVAC Systems Operation Challenges in a Modern Office Building – Case Study

“…The researches on people´s performance while working under different thermal conditions showed the results indicating lower performance during the uncomfortable air temperature period [3]. According to Niemmela et al people performance decreased by 2.2 % by every 1 °C over 25 °C [4].…”

Yra žinoma, kad per aukšta patalpų temperatūra (didesnė kaip 30 °C) gali sukelti širdies kraujagyslių nepakankamumą (Sernas 1985), akių džiūvimą (Wolkoff et al 2012) ir kitus negalavimus.

Nepaisant to, kad skaidriosios atitvaros yra silpnoji pastato dalis energiniu požiūriu, Lietuvoje ir kitose šalyse, siekiant skaidrumo įspūdžio, vis dar nemaža dalis statomų visuomeninės paskirties pastatų pasižymi dideliais fasado įstiklinimo plotais.
