Matt kept the operable window in his office open all the time because he needed unlimited access to fresh air. This was terminated after a Heating, Ventilation, and Air Conditioning system was installed in his Government of Canada office building. After Matt’s access to fresh air became mechanically controlled through extra-locally developed air quality standards, the workplace became a barrier for him. Matt was deemed to suffer from a disability known as environmental sensitivity because he became ill every time he spent more than 45 minutes inside his office building. Yet, according to a textually-mediated assessment of Matt’s workplace performed by a Compliance Review Officer from the Canadian Human Rights Commission, his workplace was barrier-free. Using Dorothy E. Smith’s institutional ethnography, this paper explicates how the social organization of workplace accommodation and compliance—processes that were developed to promote inclusion—are exclusionary.

Indoor Thermal Environment

In this study, an office building in Japan that incorporates energy-saving features and environmental technologies was investigated. This office building features a green façade, natural ventilation, a concrete slab with no suspended ceilings, and thermo-active building systems. Two airconditioning systems were installed in this building—a ceiling radiation air-conditioning system and a whole floor-blow off air conditioning system. In addition, a natural ventilation system was installed. We surveyed the heat flux of the ceiling surface and indoor thermal environment of this building from 2015 through 2016. The ceiling using the heat storage amount of concrete maintains a constant temperature in the workplace during as well as after office hours. We also performed detailed measurements of the heat flux of the ceiling surface and indoor thermal environment in the summer of 2017. The results showed that the ceiling radiation air-conditioning system provided a stable thermal environment. Furthermore, we report that making use of the thermal behavior of the skeleton improved the operation of the ceiling radiation airconditioning system.

How to maintain a comfortable indoor environment without excessively relying on mechanical HVAC (Heating, Ventilation, and Air Conditioning) is a target to be pursued for future living requirements. The results obtained in this research show that in an office environment, the room temperature monitored during winter is close to the comfortable temperature; however, the office occupants feel that a little warmer indoor temperature is comfort. During summer, the occupants prefer cooler temperature than the comfort temperature. Additionally, Taiwan is located in sub-tropical region with hot and humid summer. Even if the room temperature is maintained in a comfortable range, the occupants still feel not so comfortable because of high humidity. Hence, reducing the room temperature below 23 °C is inferred to make occupants feel comfortable. Questionnaire survey indicates that ventilation is preferred by 30.9% of the respondents for summer and 43.3% for winter as an effective method to improve the stuffy indoor air.

Air Control

The thermal comfort inside heritage buildings in China is mostly achieved with the use of split air conditioning and radiator heating system. Due to inefficiencies in the design of those systems, the regulation of air temperature is generally inadequate. To meet the thermal comfort requirements of the partial significant room, which is the meeting hall area, and to preserve the external walls and facade, this paper simulates and analyses typical working conditions of air control schemes in the gate tower and suggests the use of a floor-type fan coil air conditioning system. The results show that the proposed air distribution system can maintain a temperature of 295 K in the summer, which meets the thermal comfort requirements of the meeting hall. This method takes into account the requirement for thermal comfort, as well as the requirements of heritage preservation. Our proposal contributes to the growing literature, which studies methods of improving the thermal comfort of the indoor environment of heritage buildings.
