Contributions Regarding the Energy Efficiency Increasing for a Hotel Building in order to Ensure a Healthy Indoor Environment

摘要

This paper purpose is to provide recommendations after a thermal energy analysis and inspection of a hotel building and its related facilities, in order to increase energy efficiency saving primary resources, to ensure a healthy indoor climate for users, and last but not least to ensure a reduction of CO2 emissions in order to ensure an external environment with low pollutant emissions. All the carried out analysis has as main objective to consider a symbiosis between all the parameters involved (energy, indoor/outdoor environment, comfort), when a building (envelope and installations) is renovated, especially when excess in order to save energy tend to endanger the indoor climate. Non-invasive methods were used to inspect the building by using thermo-vision both for the building envelope and for inspection of existing installations. The building utilities bills were analyzed for a period of one year to highlight current energy performance. The given recommendations achieve the proposed goal and highlight the active role of building management, continuous monitoring of energy and utilities to assess and improve energy efficiency, and ultimately to minimize specific energy costs. The results of this study can be used successfully on a wide range of hotel buildings in Romania.
