Evaluation of vernacular and new housing indoor comfort conditions in cold climate – a field survey in eastern Turkey

Abstract

Purpose

The purpose of this study is to compare vernacular and new houses in terms of indoor occupant satisfaction and thermal and visual comfort in a region with cold climatic conditions. In line with the data obtained, the contribution of passive design techniques to comfort in housing indoor will be revealed.

Design/methodology/approach

In this study, the comfort conditions to be provided in a residence were determined and evaluated in Bingol with the help of questionnaires applied on vernacular and new houses. The information gathered from the occupants and the survey study was mainly designed for three purposes: (i) acquiring general information about houses; (ii) acquiring general information about occupants; and (iii) inquiring about the physical comfort satisfaction of the occupants (thermal comfort and visual comfort).

Findings

Although the average occupant satisfaction in terms of thermal performance in vernacular houses in summer and winter is 3.91, this average is 2.01 for new houses. The average of the general visual comfort of occupants in vernacular houses is 3.59, whereas this rate is 2.63 in new houses. According to the data obtained, occupant satisfaction was higher in vernacular houses than in new houses. In general, the new settlement area is designed and positioned independently of climate and environmental conditions. This situation increases the need to use mechanical systems to provide indoor thermal comfort conditions. The increase in the need for mechanical systems leads to a significant increase in energy expenditures, as well as deterioration of health conditions in places.

Research limitations/implications

To ensure occupant satisfaction, indoor thermal comfort conditions and healthy environments, vernacular houses should be an example for the design and building of new houses in terms of orientation, environment relations, space dimensions and space usage in accordance with the character of the region and material selection.

Originality/value

There has not been a serious research on bioclimatic, socioeconomic and cultural sustainability of the vernacular architecture of Bingol. Therefore, this region has been preferred as the study area.
