Analysis of Measures to Increase the Energy Efficiency of Dormitories of the National University of Water and Environmental Engineering

The NUWEE dormitories were built in the last century and do not meet the current requirements of energy consumption. The condition of the constructions of building elements and engineering systems of the NUWEE Dormitories # 1–6 and measures to increase their energy efficiency were analyzed. The assessment of energy consumption before and after the implementation of energy efficiency measures of Dormitories # 1–6 was made and the predicted saving of energy resources after the implementation of these measures was determined. The ranking criteria of energy efficient measures were defined and analyzed such as Financial Ranking Criteria (FRC), Environmental Ranking Criteria (ERC) and Behavioral Ranking Criteria (BRC). Implementation of the proposed energy-efficient measures will reduce energy consumption and related costs by 44% in average (compared to the basic level of energy consumption). Buildings of Dormitories # 2, 4 can achieve energy efficiency class B after the implementation of the proposed measures, the buildings of other dormitories can achieve energy efficiency class C. The implementation of energy efficiency measures in the complex will have the payback period from 14 to 16.4 years. The implementation of energy efficiency measures will also result reducing the emission of greenhouse gases by 40% in average.
