Contributions Regarding the Implementation Nzeb Concept in Existing Public Buildings

This paper purpose is to provide recommendations for a public buildings – hospital - x 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. After the thermal expertise of this building, the carried out analysis has as main objective to consider all the parameters involved (installations, insulations, indoor environment, comfort). Along with rehabilitation of a public building (envelope and installations), especially it is necessary to save energy but not 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. All the entering parameters such as 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 hospital buildings in Romania.
