Τεχνικο-οικονομική μελέτη ενεργειακής αναβάθμισης κτιρίων και ανάλυση αβεβαιότητας με την τεχνική προσομοίωσης Monte Carlo

Abstract

One of the most major problems our society faces today is the rapid growth of energy consumption. The building sector is one of the main causes. The aim of this Master Thesis is to describe the energy distribution in the building sector, the political regulations and to find possible ways of reducing the energy consumption, by presenting the results of energy building implementation. Firstly, there is a description of the major energy indexes both in Greece and the European Union (27 countries) and the legislations. A number of energy building implementations and theoretical results are analyzed. The amount of energy saved as a result of the use of the Greek software TEE-KENAK in two buildings, one block of flats and one detached house, are compared to the theoretical ones. A combination of different building implementation measures is made in order to improve the energy efficiency. According to the fuel prices, energy savings mean a lot of money savings. The internal rate of return of each possible combination of energy building implementation measures is counted to judge the effectiveness of an investment. The continuous change, in fuel and product prices, creates a lot of uncertainty about efficient investments. Monte Carlo simulation technique is used to calculate the cumulative probability of internal rate of return (IRR). Moreover, in relation to the Greek building stock, the total energy savings are counted in order to have a general image of the energy situation.
