Indoor thermal comfort and Carbon Dioxide concentration
2017 Moratuwa Engineering Research Conference (MERCon), 2017Carbon Dioxide (CO 2 ) is considered as a useful and easily measurable indicator for the ventilation and air quality of the indoor environment. Although this pollutant itself is not causing serious health issues with lower concentration and short durations, the higher concentration can indicate the lower ventilation level and possible air contamination

Building and Environment, 2014
Abstract Several short term studies have found evidence that plants may improve occupant thermal comfort, yet this phenomena has not yet been rigorously evaluated. The aim of this paper is to present the results of a quasi-experiment that evaluated the effect of indoor plants on the thermal comfort of 67 office workers within an office building in De

Indoor Thermal Comfort Control Based on Fuzzy Logic
2016Control and monitoring of indoor thermal conditions represent crucial tasks for people’s satisfaction in working and living spaces. In the first part of the chapter we address thermal comfort issues in a working office scenario. Among all standards released, predicted mean vote (PMV) is the international index adopted to define users thermal comfort ...

Indoor thermal comfort controls optimized by deducing rules
2016 18th International Conference on Advanced Communication Technology (ICACT), 2016A novel approach based on an optimization method is developed to deduce the rules of learning human thermal comfort states. In order to achieve a desired thermal comfort level and energy savings, the study constructs a mechanism with varied control strategies by using the deduced rule set. The proposed method is superior to other indoor thermal comfort

Investigation of indoor thermal comfort under transient conditions
Building and Environment, 2005In industrialized countries about 90% of the time is spent indoors. In indoor, thermal comfort can be basically predicted by the environmental parameters such as temperature, humidity, air velocity and by the personal parameters as activity and clothing resistance.

Passive Means to Improve the Indoor Thermal Comfort
2021The building should be designed and constructed first to bring a good indoor environment to its occupants. This chapter addresses thermal comfort and passive means to improve ensure it. These are thermal insulation and inertia, solar collecting area and their solar protections, natural ventilation and combinations of them allowing passive solar heating

Thermal diary: Connecting temperature history to indoor comfort
Building and Environment, 2008Abstract To explore the relationship between thermal history and indoor comfort, surveys and measurements were conducted in Seoul, Korea and Yokohama, Japan. Fifty-two subjects were recruited from university campuses in Seoul and Yokohama during the hot season in August 2002. To collect information regarding people's daily thermal history, background
