Adaptive Thermal Comfort of an Office for Energy Consumption-Famagusta Case

Abstract

The aim of this study was to determine how much thermal comfort can be obtained through heat/energy transfers between the office/external air and the transparent/opaque surfaces of an office by combining different transparent and opaque wall surface ratios with different window opening percentages using dynamic thermal simulations. It found that the optimum window-to-wall ratio (WWR) for energy conservation is 40%, with a 20% window opening ratio. The 80% and 90% thermal comfort ranges of the adaptive thermal comfort methodology are found in May, October, September, and the yearly average, while June and August are only in the range of 80% acceptability. The office constantly loses heat through air flow with any glass size on its external facade and any window opening ratio. Moreover, all sizes of opaque and transparent internal surfaces transferred heat from outside by conduction, while the opaque wall similarly always transferred energy to heat up the office air internally and outside air externally through convection. The external glass also heats the office air by convection, except in the months of January, November, and December.

Indoor Thermal Comfort from the Estimation Thermal Environment’s Physical Variables in Temperate-Dry Bioclimate

“…However, there are national [1] and international [2-6] standards that establish the technical and methodological bases to estimate these thermal indicators based on the local particularities of each case. At the same time, different authors have developed universal thermal comfort models [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] of graphic, mathematical, computer, or algorithmic type, which offer an approach to local thermal comfort [25][26][27][28][29][30][31][32][33][34] from outdoor weather and some endogenous factors of people (activity level and clothing).…”
