Investigation of Methods to Increase Energy Efficiency in Old Buildings: A Case Study on a School Building Constructed in 2007
Abstract
In this study, the energy efficiency study of the school building whose construction was completed in 2007 was conducted. First of all, information about energy consumption and the amount of CO2 emission released into the atmosphere was obtained by measuring the building elements, heating system, piping and lighting system. Afterward, some suggestions were made in the areas where energy consumption is high and inefficient, in line with efficiency-increasing methods, considering the relevant standards and regulations. Finally, with these proposed improvements, the energy savings of the building, the economic value of this savings and the reduction in carbon emission are calculated. As a result of the study, 65.04 kWh/m2 energy and 0.012 tonCO2/m2 carbon emission savings per unit area, 334 379 kWh/year energy and 66.18 tonCO2/year carbon emission savings, the investment cost of 319 653 TL as 65.2 TL/m2 per unit area., and 6.1 years payback period was calculated.
