  • Climate Change and Bio-Diversity

    • Authors: Shabnam Ara, Maisnam Sandhyarani Devi
      Pages: 37 - 41
      Abstract: Climate change has become a common phenomenon now a days. Both natural as well as the human factors are responsible for it, but the changes have been accelerated by mainly human activities on large extent. Due to climate change the life of bio-diversity are underthreat. Many species have already extinct and many are on the brim of extinction. Due to loss of habitat and food of the animals they are force to migrate different places which may be not suitable for them. Here in this paper an attempt has made to identify the factors responsible for climate change and how far this climate change has affected the life of the plants and animals.  The research is purely based on the secondary source of data collect through the internet.

  • Sustainable Practices Improving the University Campus: Feasibility of A
           Photovoltaic System

    • Authors: Jandira Menezes, J.C. Cury, L.M. Souza
      Pages: 43 - 53
      Abstract: This article aimed to discuss the principles of sustainability applied to the built environment, highlighting the importance of universities as replicators of these practices. To respond to a demand from the campus for more security in the energy supply, the work proposes the implementation of a solar photovoltaic energy system. For this, it carried out an economic viability analysis through bibliographic review activities, characterization of the study area, dimensioning of photovoltaic systems, budgets, cost analysis and payback calculation. The research evaluated the system’s implementation considering two energy demands, for the entire campus and for a smaller building. It was found that the CSL-UFSJ consumes, on average, 27,300.38 kWh, at a cost of US$ 2,736. Thus, an annual savings of US$ 32,833 is calculated. The cost estimate analyzes showed a value of US$ 139,784 for the implementation of the system. The return on investment time was calculated for 4.3 and 4.9 years considering simple and discounted Payback respectively.It is estimated that the consumption of the DECEB building is 13,187.1 kWh with a cost of US$ 1,322 per month, which results in an annual savings of US$ 15,860. The cost estimate analyzes showed a value of US$ 40.601 for the implementation of the system and values of 4.3 and 4.9 years were obtained as return on investment time considering the calculations for simple and discounted Payback, respectively. The research demonstrates that the implementation of the photovoltaic solar energy generation system is feasible for both cases analyzed.
