Factors Effecting the Total Volatile Organic Compound (TVOC) Concentrations in Slovak Households.

Abstract: Thirty five Slovak households were selected for an investigation of indoor environmental quality. Measuring of indoor air physical and chemical factors and a questionnaire survey was performed during May 2017. The range of permissible operative temperature was not met in 11% of objects. Relative humidity met the legislative requirements in all monitored homes. Concentrations of total volatile organic compounds (TVOCs) were significantly higher in the apartments than in the family houses. The average TVOC levels in the apartments and family houses were 519.7 µg/m3 and 330.2 µg/m3, respectively. Statistical analysis confirmed the effect of indoor air temperature, relative humidity and particulate matter (PM0.5 and PM1) on the levels of TVOCs. Higher TVOC levels were observed also in homes where it is not a common practice to open windows during cleaning activities. Other factors that had a statistically significant effect on concentrations of volatile organic compounds were heating type, attached garage, location of the apartment within residential building (the floor), as well as number of occupants. Higher TVOC concentrations were observed in indoor than outdoor environment, while further analysis showed the significant impact of indoor emission sources on the level of these compounds in buildings. The questionnaire study showed a discrepancy between objective measurement and subjective assessment in the household environment, and pointed to insufficient public awareness about volatile organic compounds (VOCs).

Investigation of Indoor Air Quality in Houses of Macedonia.

Abstract: People who live in buildings are exposed to harmful effects of indoor air pollution for many years. Therefore, our research is aimed to investigate the indoor air quality in family houses. The measurements of indoor air temperature, relative humidity, total volatile organic compounds (TVOC), particulate matters (PM) and sound pressure level were carried out in 25 houses in several cities of the Republic of Macedonia. Mean values of indoor air temperature and relative humidity ranged from 18.9 °C to 25.6 °C and from 34.1% to 68.0%, respectively. With regard to TVOC, it can be stated that excessive occurrence was recorded. Mean values ranged from 50 μg/m3 to 2610 μg/m3. Recommended value (200 μg/m3) for human exposure to TVOC was exceeded in 32% of houses. Mean concentrations of PM2.5 (particular matter with diameter less than 2.5 μm) and PM10 (diameter less than 10 μm) are determined to be from 16.80 μg/m3 to 30.70 μg/m3 and from 38.30 μg/m3 to 74.60 μg/m3 individually. Mean values of sound pressure level ranged from 29.8 dB(A) to 50.6 dB(A). Dependence between characteristics of buildings (Year of construction, Year of renovation, Smoke and Heating system) and data from measurements (Temperature, Relative humidity, TVOC, PM2.5 and PM10) were analyzed using R software. Van der Waerden test shows dependence of Smoke on TVOC and PM2.5. Permutational multivariate analysis of variance shows the effect of interaction of Renovation and Smoke.

Risk-Aversion and Willingness to Pay For Energy Saving Measures in Residential Buildings

Abstract: This paper uses a choice experiment to evaluate the consumers' willingness to pay for energy-saving measures in Switzerland's residential buildings. These measures include air renewal (ventilation) systems and insulation of windows and facades. Two groups of respondents consisting respectively of 163 apartment tenants and 142 house owners were asked to choose between their housing status quo and each one of the several hypothetical situations with different attributes and prices. The estimation method is based on a fixed-effects logit model. The results suggest that the benefits of the energy-saving attributes are significantly valued by the consumers. These benefits include both individual energy savings and environmental benefits as well as comfort benefits namely, thermal comfort, air quality and noise protection.

Indoor Air Quality and Health

Abstract: In the last few decades, Indoor Air Quality (IAQ) has received increasing attention from the international scientific community, political institutions, and environmental governances for improving the comfort, health, and wellbeing of building occupants.[...].

Renewable energy technologies for sustainable development of energy efficient building

Abstract: The energy conservation through energy efficiency in the building has acquired prime importance all over the world. The four main aspects for energy efficiency in a building include first and foremost the nearly zero energy passive building design before actual construction, secondly the usage of low energy building materials during its construction, thirdly use of energy efficient equipments for low operational energy requirement and lastly integration of renewable energy technologies for various applications. These aspects have been discussed along with their economics and environmental impacts briefly in this paper. The first aspect is related to the prior design before construction of a solar passive building techniques adapted all over the world not only for passive heating/cooling but also for daylighting the building. Second is utilizing the low embodied energy building materials for building construction. The third aspect deals with the operational energy conservation using energy efficient equipments in the building. Lastly, the building has to include utility of integrated renewable systems for hot water heating, solar photovoltaic electrification, etc.

Adsorption of methylene blue onto activated carbon developed from biomass waste by H2SO4 activation: kinetic, equilibrium and thermodynamic studies

Abstract: Sulphuric acid (H2SO4) was utilized as an activator for the preparation of activated carbon from a biomass solid waste, coconut leaves. The sulphuric acid-treated activated carbon (SAC) was used as low-cost adsorbent for the removal of methylene blue (MB) cationic dye from aqueous solution. Adsorption of MB using SAC from aqueous solution under equilibrium and kinetic conditions in batch mode was evaluated by varying adsorbent dose (0.2–2.5 g/L), solution pH (3–11), initial dye concentration (30–400 mg/L), contact time (0–180 min) and temperature (303–323 K). The Langmuir isotherm model showed better fit to the equilibrium data than the Freundlich model. The adsorption capacity (qm) of SAC increased with temperature where qm varied as follows: 126.9 (303 K), 137.0 (313 K) and 149.3 mg/g (323 K). The kinetic uptake results were well described by the pseudo-second-order (PSO) kinetic for each temperatures. The thermodynamic adsorption parameters (∆G°, ∆H° and ∆S°) were driven by favourable entropic ...
