Family House

Nowadays, there is an increased trend in the construction of nearly zero energy buildings which can be also characterized as green buildings. Several studies confirm that wooden buildings fulfil these requirements. However, there is no detailed research related to the quality of the indoor environment in new wooden family houses. For this reason, this paper focuses on monitoring of the indoor environmental quality in a selected wooden family house. Short-term measurements are aimed at investigation of physical parameters (air temperature, relative humidity, air velocity and noise) and chemical factors such as concentrations of particulate matters and CO2. At the same time, environmental impacts were also assessed for impact categories such as: global warming potential (GWP), ozone depletion potential (ODP) acidification potential (AP), eutrophication potential (EP), photochemical ozone creation potential (POCP) ex-pressed as kilogram CO2eq, CFC11eq, SO2eq, PO43–eq and kilogram of C2H4eq within “Cradle to Grave” boundary by using the life cycle assessment (LCA) method. The main contribution of this study is demonstration that wooden build-ings have substantial share in the reduction of environmental impacts. So far, results indicate that the design of wooden houses correspond with the increasing demands of occupants in terms of environmental, social and energy performance.

The Difference

This study was done to investigate the relationship between indoor environmental quality and prevalence of Sick Building Syndrome in six small offices inPenangIsland. Indoor environmental quality measurement was conducted according to relevant standards. There are totally Sixty workers were selected to participate in an electronic questionnaire survey. Questionnaire was used to record the comfort level of respondents in the case studies and level of sick building syndrome faced by respondents. Through indoor environmental quality measurement, it is found that most of the offices facing the lighting and noise problem. The result from the questionnaire shows that in overall, the occupants satisfy with their working environment in term of indoor environmental quality although the result also shows the opinions of occupants on dissatisfaction on certain indoor environmental parameter according to case study. The study also found that most of the occupants feel drowsy and fatigue when they work within the offices. Besides, due to the difference of the indoor environmental quality of the buildings, the occupants are suffered from different symptoms of the sick building syndrome.

The One

Decent quality of indoor air is important for health and wellbeing of building users. We live, work and study in indoors of various types of buildings. Often people are exposed to pollutants at higher concentrations than these that occur out-doors. Continual investigation of indoor air quality is needed for ensuring comfort and healthy environment. Measuring and analysis of occurrence of physical, chemical and biological factors is the first step for suggestion of optimization measures. Inside school buildings there are often inadequate indoor climate conditions such as thermal comfort parame-ters or ventilation. The aim of this study was determination of indoor environmental quality in selected offices in the building of elementary school in Slovakia. The values of operative temperature were not within the optimum range of values for the warm period of the year in one of the monitored offices. The intensity of illumination was lower in the two offices. Low levels of particulate matters were measured except the one office where permissible value was exceeded by 7.6%.

Do So

In the Mediterranean climate, a large number of educational buildings suffer from discomfort due mostly to energy-deficient thermal envelopes and a lack of cooling systems. Impending climate change is expected to worsen overheating in classrooms, especially during heatwave periods. Therefore, the protection of window openings to reduce incident solar radiation while maintaining adequate indoor environmental quality must be considered a necessary key focus. The main objective of this research is to assess the influence of an egg-crate shading device on the indoor environmental quality of a classroom in Southern Spain. To do so, two classrooms—with and without this shading device—were simultaneously monitored over a whole year. The implementation of an egg-crate shading device allowed for a significant reduction of the incident solar radiation, both in summer and mid-season (around 45–50%), which objectively slightly conditioned indoor operative temperatures. Given the noticeable influence of the user patterns observed, indoor illuminance was also improved, as the rolling shutters tended to be opened at higher aperture levels.
