The Comparative Study

Human behaviors that greatly influence building energy consumption are stimulated by the indoor environment. However, the relative importance of different environmental factors remains unclear. Previous literature mostly focused on single behavior. Holistic study of multiple energy-related behaviors is scarce. To fill the gap, this study investigated 22 government office buildings in Sichuan using questionnaires and field measurement. Environmental factors were ranked based on the two dimensions of “importance level’level” and “satisfaction level”. The key energy-related behaviors were identified by the comparative study between low- and high-energy-consuming buildings. Lastly, interactions between the building energy consumption, indoor environment quality, occupants’ satisfaction, and human behaviors were analyzed. Questionnaires reveal that most occupants consider indoor air quality as the prior “pain point” while feeling satisfied enough with the thermal environment. Although people attach less importance to the acoustic environment, they manifest evident discontent, suggesting that noise control is an urgent imperative. In contrast, occupants are relatively unconcerned with illuminance, which implies the feasibility of saving energy by reasonably reducing lighting requirements of some non-critical areas. The comparative study indicates that increased energy consumption was attributable to extra personal appliances, wasteful air conditioning habits, and the lack of ventilation in summer. The objective environment of high-energy-consuming buildings is slightly better. However, the difference in perceived satisfaction was not obvious. The findings of this study contribute to determining the most noteworthy environmental factor and the key energy-related behaviors and provide reference information for optimizing energy-saving strategies.

While previous research has shown the use of attachable air-caps on windows to efficiently reduce a building’s energy consumption, the air-caps considered had to be attached to the entire window’s surface, thus limiting the occupants’ view and creating the inconvenience of needing to detach and attach the air-caps. In this study, a window-mounted air-cap roller module using Velcro tape that may be easily attached, detached, and rolled up or down was developed and performance tested in a full-scale test bed. It was found that as the area of the air-caps attached on a window increased, the required indoor lighting energy increased. However, the window insulation improved, thus reducing the cooling and heating energy needed. Attaching the air-caps to the entire window surface effectively reduced the building’s energy consumption, but views through the window may be disturbed. Thus, the developed window-mounted air-caps enable an occupant to reduce the building energy consumption and maintain their view according to their need. The findings of this study may contribute to a reduction in building energy consumption without sacrificing a pleasant indoor environment. Further studies may be needed to verify their efficacy under varying indoor and outdoor conditions.

Building Energy Conservation

Building energy conservation has become the worldwide tendency since the mid-1970s. The Theory of Sustainable Development raised in 1990s as well as the deterioration of ecological environment made the building energy conservation became the international focus all over the world. China is a country with high energy consumption and large population and the percentage of its building energy consumption has reached about 25% on total energy consumption. The energy conservation condition of building external wall is one of the direct influencing factors of thermal comfort of indoor environment. However, greening is a kind of natural sunshade of the nature. The key to the study is how to improve the temperature of building walls and thermal comfort of indoor environment by the way of greening sunshade of external walls.

The Impact

Energy performance guarantee projects aim at achieving a given energy consumption in real life conditions. Building energy consumption monitoring during operation phase often reveals that energy consumption is sensitive to building spaces use and systems operation quality, especially for buildings with high energy performance characteristics [7]. Other investigations show the impact of building users’ behaviour on energy consumption [28]. These factors must be added to climate factors for energy consumption prediction during operation phase. Number of factors and possible combinations is very high. Building energy modeling is limited regarding this issue and metamodeling has been used to solve this problem [25]. We developed metamodels that are polynomial functions using D-optimal design of experiment (DOE) approach. Such metamodels can become operational tools to use in the IPMVP framework, associated with a M&V plan. This paper shows the application of the method on a cultural building that comprises numerous systems and usages. We obtain a reliable metamodel of the energy consumption as a function of climate, operation, and space use factors. which meets IPMVP [11] and ASHRAE Guideline 14 [3] modeling uncertainties criteria. We also determine the global uncertainty resulting from predictors’ uncertainties propagation and modelling uncertainty associated with the metamodel.

According to the United Nations Intergovernmental Panel on Climate Change (IPCC) calculations, the architecture industry totally consumed 40% of the energy and 36% of CO2 emissions in world. The large public building with rapid floor area growth, high-energy consumption and huge potential for energy saving features, is a key area of energy conservation obviously. This paper researched the trend of low-carbon building construction and high building energy efficiency, the public building energy consumption and its carbon emissions effect. Moreover, consumption and carbon emission of different types of public building energy was analyzed. Estimation methods on public building energy consumption and carbon emission were summarized in the last part.

Passenger Station

Port passenger station buildings (PPSD) are an important part of transportation buildings in China, which is characterized by large human flow, long operating time, high load of equipment and lighting. The characteristics and functions of PPSD lead to the high energy consumption. However, the energy consumption analysis of PPSD was deficient. In this paper, the characteristics of energy consumption of port passenger stations in cold regions and hot summer and warm winter regions in China were analyzed. Based on eQUEST, the building models of port passenger stations are established. The influencing factors of the building energy consumption were analyzed through orthogonal experiment with SPSS. Results show that the factors such as summer indoor design temperature, heat source form, air conditioning form, window to wall ratio and lighting control mode are the key factors affecting the energy consumption of port passenger station.

Indoor Environment Quality

This study reviews some published literatures to survey the recent research on indoor environment quality and building energy consumption. The indoor environment quality is categorized and defined as different indices and variables. The building energy consumption can be determined by ventilation rates, thermal comfort, adaptive thermal comfort, neutral temperature, set-point temperature, indoor air quality, air velocity, and non-occupied hours. Various climates or regions such as subtropical climates in Hong Kong, Italy, three climatic zones in Greece, hot and dry climates in Africa, hot and humid climate in Thailand, are contained. The building types include office buildings, commercial buildings and school buildings, and the data can be obtained from a simulation model or the field database. It can be concluded that the indoor environment quality has a significant influence on the building energy consumption, and a validated thermal model is be a practical tool to investigate the effect of the indoor environmental parameters.
