Résumé

The energetic revitalization of an object has the biggest potential to save energy and prevent greenhouse gas emissions in the construction industry. One of the most efficient measures is changing coal boilers for central heating to pellet boilers. This measure was successfully implemented at “Karaburma” Elderly Care Center in Belgrade. The center consists of 9 houses (built in 1963), and during the winter the Center uses its own boiler for heating. The study presents the comparison of a Savings Plan (created before the change of boilers) and actual savings (after the change of boilers). Theoretical approach was based on the analysis of energetic qualities of the object in the stage of investment plan, using the method of mathematical modeling which was published as a part of work named “Revitalization of architectural objects by means of energy efficiency improvement: An economic case analysis”. The study describes, through measurement, the consumption of pellet as energy-generating product (after the change of coal boilers to pellet boilers) during one heating season. A comparison was made with the results expected in the planning stage. However, in the phase of boiler change implementation, the way decisions were made transformed compared to the planned investment. Somewhere between theory and practice, we analyze the difference between parameters envisaged in pre-calculations and those achieved later. Common denominator is a referent unit (kWh) and the time of investment return. The study presents the comparison between expected time for investment return and return through reduced consumption of energy-generating products and measured value for one heating season. Facts presented show the economic efficiency of the investment from two points of view: theoretical and practical; both have positive consequences for the environment, as a result of coal not being used as an energy source. Rational energy consumption and environment protection are a key element of energy policy in a number of countries nowadays, as well as one of the most important issues for sustainable development. Careful investment plan and its implementation - in other words, harmony between theory and practice - would be an important contribution to the process of resolving a major development problem in the Republic of Serbia.
