Abstract

Improvement of the energy efficiency of public buildings appears to be one of the best ways to simultaneously reduce energy consumption as well as the negative impacts on the environment. The work is dedicated to the analysis of modernization process of the energy system in a sports facility in a way leading to design of smart energy system. The proposed solution, being a specific case study, offers optimal use of energy in the facility, significantly reducing the demand for energy derived from fossil fuels (heat providers and conventional power plants). The project, on its first step, consists of recovering energy from sewage that usually is irretrievably lost. This option allows to achieve the assumed goals simultaneously optimizing the investment costs. The proposed solution mitigates air pollution and harmful gas and dust emissions to the atmosphere, and contributes to an increase of both the attractiveness and competitiveness of the area in which the sports facility is located. The next step will be further automation of the system and intelligent synchronization of time-dependencies of the processes.

Highlights

  • Water deficit along with the need of environmental protection coupled with ever-increasing civilization progress forces us to save energy, water and materials [1,2,3,4]

  • Heat recovery from rinsing wastewater realized due to the application of the AquaCond installation is an innovative treatment method for wastewater intended for sewage discharge

  • The plant for heat recovery from the rinsing wastewater located in the Municipal Sports Center is not a fairly popular device but it has been ideally designed for this type of processes:

Summary

Introduction

Water deficit along with the need of environmental protection coupled with ever-increasing civilization progress forces us to save energy, water and materials [1,2,3,4]. Intelligent energy management systems are becoming increasingly popular [13,14]. Their attractiveness is due to the innovative perception of the energy sector, including issues related to monitoring, controlling, and collecting data. The purpose of their use is communication between all participants of the energy market, with the task of providing energy services, ensuring reduction of costs, and increase of efficiency as well as integration of distributed energy sources, including renewable energy. Intelligent networks give the opportunity to dynamize the development of energy technologies [15,16]. The smart systems integrate various resources and technologies in both generation and consumption
