This paper does the simulation analysis of the annual energy consumption of an office building and the simulation of the whole GSHP(Ground Source Heat Pump) air conditioning system operation for two years. With the dynamic load, The simulation of the temperature field is done about the ground heat exchanger soil area with the radius of 2.5m during the heating period and the downtime. The result shows that soil temperature variation decreases gradually from the center to the distal end, in the first five days after shutdown, the soil temperature recovers faster, and then gradually becomes slowlier.

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.

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.

Chilled Water System

As the scale of the air conditioning system is constantly increasing, some problems still exist and remain to be solved in the chilled water system. Among them, the leading problems lie in the insufficient research of the overall character on the user side and lack of simulation analysis. Corresponding calculating procedures are mixed programmed using VB and FORTRAN language to conduct to simulating analysis, to testify reliability and feasibility of the method.
