Energy Consumptions

The energy refurbishment of the existing building heritage is one of the pillars of Italian energy policy. Aiming for energy efficiency and energy saving in end uses, there are wide and diversified improvement strategies, which include interventions on the building envelope and Heating, Ventilation, and Air Conditioning (HVAC) systems, with the introduction of renewable energy sources. The research aims at evaluating the building energy consumptions and Indoor Environmental Quality (IEQ), varying the airflow rates handled by the HVAC system. A Case Study (the Aula Magna of a university building) is analysed; an in-situ monitoring campaign was carried out to evaluate the trend of some environmental parameters that are considered to be significant when varying the external airflow rates handled by the HVAC system. Additionally, dynamic simulations were carried out, with the aim of evaluating the energy savings coming from the airflow rates reduction. The results of this case study highlight the opportunity to achieve significant energy savings, with only slight variations in IEQ; a 50% reduction in airflow rate would decrease energy consumption by up to 45.2%, while increasing the carbon dioxide concentration from 545 ppm to 655 ppm, while the Particulate Matter and Total Volatile Organic Compounds increase is insignificant.

<p>Heavy metal is one of the most pollutant loads that endangers the aquatic environment. Not only damaging the aquatic ecosystem, the presence of heavy metals also endangers the human health. This Research aims to determine the levels of heavy metals, especially Pb, Cu and Zn in water and also the sediments inside Kendari Bay waters. To determine the environmental quality of Kendari Bay waters standards, Sampling was carried out at 10 stations and sample analysis was carried out using the AAS method. Data analysis was performed using descriptive methods. The results showed that heavy metals Pb, Cu and Zn in water ranged &lt;0.002 - 0.012 mg / L, for metals ranging from &lt;0.002 - 0.003 mg / L, Cu metals ranged from &lt;0.002 - 0.012 mg / L and Zn metals ranged from &lt;0.002 - 0.003 mg / L, while heavy metals Pb, Cu and Zn in sediments range &lt;0.002 - 0.047 mg / kg, for Pb metals range from 0.052 to 0.047 mg / kg, Cu metals range &lt;0.002 - 0.042 mg / kg and Zn metals range from 0 , 0019 - 0.011 mg / kg. The heavy metal content of Pb, Cu, and Zn in both water and sediment samples has not exceeded the quality standards based on the Decree of the Minister of Environment No.51 of 2004 and USEPA.</p><p><em>Keyword</em><em>s</em><em> : kendari bay, heavy metal, Pb, Cu, Zn</em><em></em></p>

Economic Productivity

East Java has shown strong economic growth, which negatively affects its environmental quality. Analysis of the functional relationship between economic growth and environmental quality is important to direct the growth without further deteriorate the environmental quality in this area. It is assumed that growth produces some externalities on environmental quality. The spread of technological information, economic productivity, population growth or investment, can be the source of the growth externalities. The objective of this study is to test the significance of the involved growth externalities on East Java’s environmental quality. Using spatial data, the externalities are accommodated in a spatial version of the STIRPAT model. It is estimated using per city/regency 2015 data. The analysis indicates that local density, local agricultural productivity, neighboring density, and neighboring mining activity significantly affect the local environmental quality. The latter two are the main sources of the growth externalities.

Water Environmental Quality

In this paper, the parallel coordinates’ method is used for analyzing the marine water environment quality. The environment status could be obtained by this method intuitively. In this paper, the water environment quality in the Caofeidian marine district is analyzed. Multiple pollutants in the multiple years are used. The results show that the water environmental quality in the Caofeidian marine district is acceptable, the environmental status could be obtained by the parallel coordinates’ method visually, which is the main advantageous of this method.
