Abstract

Reducing energy consumption and maintaining an appropriate indoor air quality in buildings is a global trend. This is achieved in several ways – improving the building envelope thermal characteristics; fuel base replacement; introduction of smart energy consumption tracking systems. The aim of this paper is an analysis of the impact of energy efficiency measures introduced in buildings that provide health services. Measures have been taken to improve the energy performance of the envelope, as well as to modernize the system for the production and distribution of thermal energy. One complete year after energy savings measures implemented the total energy savings of 37.9% have been achieved. Further economic assessment has been made regarding the profitability of the applied measures.

Highlights

  • Issues related to increasing energy efficiency in buildings have been relevant over the past three decades

  • The paper points out that the high share of energy consumption is due to the poor thermal performance of the enclosures, the inefficient operation of HVAC systems (Heating, Ventilation, & Air Conditioning) and the lack of or poor management of energy consumption

  • The survey shows that the energy consumption of the building is significantly higher than the standard for this type of buildings, measures are recommended to increase the energy efficiency

Summary

Introduction

Issues related to increasing energy efficiency in buildings have been relevant over the past three decades. Some papers [2,3,4,5] examine the effect from some of the most commonly applied energy-efficient measures in municipal and public buildings. For this purpose, energy audits were carried out using different mathematical approaches to model energy consumption. In some cases, when the cost of the energy used is low and the investment is significant, the measure is unprofitable [7] In this case, different cofinancing mechanisms (whether national or international) are available to promote energy efficiency improvement in buildings.
