This study aims to determine the level of air quality in the parking building based on the pollution content in it (CO, CO2, HCHO and, VOC), to analyze the effect of the weather, intensity of motorized vehicle traffic, and surface elevation to the air quality. The dependent variable is the level of air pollution. The research sample is the Makassar Bosowa Tower Parking Building, data collection was carried out by direct measurement and observation in 12 days from November 24th till December 17th. The research was done using the comparative method, The data processed using the Mann-Whitney difference test, and the Spearman correlation test using SPSS application. The results showed that the average CO levels had exceeded the limit of good air quality, the average of CO2 levels was still within the limits for good air quality, and the average of HCHO and VOC levels were mostly within the limits for good indoor air quality, according to The Indonesia Minister of Health Regulation Number 1077 in 2011. The result of measurements and tests shows that the changes in the weather do not have a significant effect on the air quality. The amount and the intensity of motorized vehicle traffic affect the air quality, especially during rainy weather.

Nowadays, people spend an average of 87% of their time inside buildings, and about 69% at home. Hence, it is essential to ensure the highest possible level of indoor air quality (IAQ). Providing that the quality of the outdoor air is acceptable, the IAQ level is improved by increasing the ventilation rates. However, this means that a larger volume of air must be cooled down or warmed up to ensure the same level of thermal comfort. The aim of this study was to conduct a cost–benefit analysis of the IAQ in residential buildings. A case-study building was defined, and three sets of materials with different pollution emission levels were chosen: High, low, and very low. For each option, the ventilation rates required to have the same IAQ level were calculated, and the consequent energy consumption and costs were estimated by means of dynamic thermal simulation. The results show the range of the initial capital cost that could be compensated for by lower running costs, and the effect of each energy and economic input assumption on the appraisal of the affordable capital cost. In the discussion, insights into the IAQ co-benefits are also given.

Indoor air quality (IAQ) is one of the most important elements affecting a building user’s comfort and satisfaction. Currently, many methods of assessing the quality of indoor air have been described in the literature. In the authors’ opinion, the methods presented have not been collected, systematized, and organized into one multi-component model. The application purpose of the assessment is extremely important when choosing IAQ model. This article provides the state-of-the-art overview on IAQ methodology and attempts to systematize approach. Sub-models of the processes that impact indoor air quality, which can be distinguished as components of the IAQ model, are selected and presented based on sensory satisfaction functions. Subcomponents of three potential IAQ models were classified according to their application potential: IAQ quality index, IAQ comfort index, and an overall health and comfort index. The authors provide a method for using the combined IAQ index to determine the indoor environmental quality index, IEQ. In addition, the article presents a method for adjusting the weights of particular subcomponents and a practical case study which provides IAQ and IEQ model implementation for a large office building assessment (with a BREEAM rating of excellent).

<p>This paper presents results from a case study on IAQ in a residence where the occupants complained about health problems during a few years’ time including infants after they changed the flooring to a new parquet flooring in both the floors. During the last years the health conditions of the children became very bad resulting into several emergency visits to the hospital. This study presents measured values for VOC and aldehydes under different conditions. Initial measurements showed that the values were very high and exceeded all the recommended health Hazard limits. This resulted into the decision that all the parquet flooring was removed. This study shows how the values of VOC and aldehydes decreased with time and also the decrease did not follow the general diffusion principles. Therefore, forced ventilation conditions under elevated temperature and very high relative humidity were used to accelerate the release rate. This study shows that elimination of volatiles was a very slow process and it took almost 30 days to achieve acceptable concentration levels both for the aldehydes and for the VOCs.</p> <p> </p> <p>This case study shows for the first time that although such flooring material meets the standard, how they may influence the IAQ of residential houses. In case if such contaminations occur, this study also shows that how the reduction rates of chemicals and specially aldehydes in indoor air could be accelerated by using different accelerated ventilation conditions. The study shows that the health hazards due to the presence of aldehydes in indoor air are underestimated in normal IAQ control routines. Since, aldehydes are classified as carcinogens, the study shows that measurement of aldehyde concentrations in indoor air should always be included in the indoor air quality control to assure a healthy indoor air climate. <b><i></i></b></p>
