Comparisson of heating and cooling charactiristics of an office building by Madrid and Vilnius climatic zones

摘要

Nowadays, one of the main concerns that we have in our lives is the quality of life, which has resulted in an increasing of the energy consumption over the history. Therefore, the real challenge that we face against is to be able to cover the energy needs and comfort of all over the world, that is what we need to take efficiently advantage of all the energy sources we have.In this case we are going to study and designing the heating and cooling system of an office building and we will make an energetic comparison of this building between Vilnius (Lithuania) and Madrid (Spain). We will see how different are the climatic conditions and how these conditions make different the normative parameters used in the calculations for the heating and cooling systems.The main objective of this work is the study and comparison of the energy needed to achieve a comfort temperature inside of an office building in Madrid and Vilnius, and to observe which are the differences between them and what would happen if we build the office building in Vilnius with the normative parameters of Madrid.For it, we will mainly take into consideration the thermal transmittance of the envelope elements which the building is built with, the heat losses due to ventilation, the heat gains due to internal sources like persons, light, equipment and of course the climatic conditions of each country. Everything will be done with the normative values found in CTE (‘’Código Técnico de la Edificación’’) and in the RITE (‘’Reglamento de Instalaciones Térmicas en los Edificios’’), in the case of Madrid. In the case of Vilnius we will take the normative parameters usually accepted and used for the designing of heating and cooling systems.
