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.

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.

The City

The green building or green architecture has come to light as a strong architectural movement at the end of 1990's and as a main trend in architectural practice. The architectural green is a modern architectural philosophy which deals with the competent relationship between the functional constructive systems and its vital environmental, by controlling the inputs and outputs of this system with the least negative effects on the environment and occupant's health, and the least energy consumption during the various stages of the building ( construction, operation, maintenance and destruction ) to achieve the functional activities and the inventive and efficient architectural structures. The importance of this movement lies in trying to achieve the sustainable development in its environmental, social and economic aspects because of the problems that developed and developing countries ( e.g. Iraq ) face such as energy consumption and pollution. Several international standards of different classifications, depending on local context of each country, has been appeared. Some of these tools are (BREEAM, LEED, CO-CHPS Colorado, GBTool, CASBEE) which aim to assess the performance of the building from green Architecture's perspective. Although there is a similarity in the classification levels including the sustainable location, how to use (water, energy and atmosphere, materials, resources) effectively, indoor environment quality and the design's innovation, they differ in other aspects that its importance relies on the environmental and local context. The problem of our research was the absence of the practical evaluation tool of the green building ( school buildings ) for the Iraq's local context in general and Mosul in particular, compatibly with the city climate. The research aims at making theoretical construction to identify the assessment indicators of the school buildings from green architecture's perspective, in order to create suitable and general assessment tool for schools building in Mosul city which can help improving the performance of these schools, decreasing the effect on the health, sparing energy coasts, and other benefits in the stages of the project ( pre-construction, construction, post-construction ). The research supposes that the multi-dimensional designing strategy is an active tool used in establishing the tool classification of assessment. For reaching goals, the research adopts the theoretical method and questionnaire. Finally, the research provides an assessment tool for school building in Mosul from the green architecture's perspective (AGBS) Green Building Assessment Tool for school ) in conformity with the local context of the city for enabling the designer to follow it in order to achieve the investment within his school architectural products. Results indicate six categories for assessment tool. First Sustainable Sites category (SS) which have the greatest weight 25.7%, , then Indoor Environment Quality(IEQ) 24.35667%. then Materials & Resources (M&R), Energy & Atomosphere (A&E), Water Efficiency(WE),and Innovotion in design (ID), have 17.32% ، 10.5% ، 3.987181% , Respectively.

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.

Acoustic Conditions

Recently, many facilities have completed new laboratories that may be used to assess various measures of Indoor Environment Quality (IEQ) in office spaces. Also recently, a new standard, ISO 3382-3, was released for assessing the effects of speech on IEQ in open plan offices. The aim of this report is to assess one room of the IEQ lab using the ISO 3382-3 standard. It is expected that the data gained will be of help to researchers using the facility in the future. Keywords: ISO 3382-3, Indoor Environment Quality, Acoustics
