Abstract
In the buildings with large glazed areas the biggest problem is the space overheating during the warm season. This causes increased energy demand for cooling. The survey was carried out during the warm and cold seasons in two office buildings with large glazed areas. The methodology was prepared for evaluating indoor climate parameters using objective and subjective evaluation. The measurements have shown that there are problems with lighting in workplaces of both buildings during both the warm and cold seasons. The biggest problem is too dry air during the cold period, an acceptable temperature is also not always in the building No. 2. The survey has shown that some employees are dissatisfied with the indoor climate in the workplace, the bigger dissatisfaction is in building No. 2. Assessing according to the O. Fanger methodology was obtained that the number of PPD is in the normal range during the cold period, whereas close to the limit when the building can not be operated in the warm period.

Summary
Violeta MOTUZIENĖ1, Violeta MISEVIČIŪTĖ2 Vilniaus Gedimino technikos universitetas, Vilnius, Lietuva. Siekiant skaidrumo įspūdžio, vis dar nemaža statomų visuomeninės paskirties pastatų dalis pasižymi dideliais fasado įstiklinimo plotais. Šiame straipsnyje pateikiamas dviejų administracinių pastatų su dideliais įstiklinimo plotais mikroklimato tyrimas šiltuoju ir šaltuoju metų laikotarpiu taikant dvi metodikas: objektyviąją (matavimai) ir subjektyviąją (apklausa). Kad tiek šiltuoju, tiek šaltuoju metų laikotarpiu abiejuose pastatuose kyla problemų dėl apšvietos darbo vietose. 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. Kaip rodo tyrimai, netgi energiškai efektyviuose pastatuose ne visada pavyksta užtikrinti tinkamas komforto sąlygas (Menzies, Wherrett 2005). Pagal galiojančius reikalavimus pastatytų pastatų su sąlygiškai dideliais fasadų įstiklinimo plotais mikroklimato parametrus ir įvertinti visuminį komfortą juose
