Abstract

Energy Performance Contracting (EPC) can help the European Union (EU) in accelerating the cost-effective renovation of existing building stock. However, there are many risks and barriers that can inhibit the application of EPC. These barriers include uncertainty about building data, lack of quality assurance regarding the post-renovation energy performance, and process complexity. In order to cross these barriers, this paper presents ModSCO. ModSCO is a web application based on a Reduced Order grey-box Model (ROM) able to systematically quantify the energy savings achieved through Energy Conservation Measures (ECMs) utilising the schema of the International Performance Measurement and Verification Protocol (IPMVP). The benefits of utilising ModSCO in terms of accuracy and time savings are demonstrated with a comparison with a whole building energy model developed with IES-VE.

  • Buildings are responsible for approximately 40% of European Union (EU) energy consumption and 36% of the greenhouse gas emissions

Summary

Introduction

Buildings are responsible for approximately 40% of European Union (EU) energy consumption and 36% of the greenhouse gas emissions. To increase the building’s energy performance, the EU has established a legislative framework with the scope of achieving a highly energy efficient and decarbonised building stock by 2050. To do so, it needs to create a stable environment for investment decisions and enable consumers and businesses to make more informed choices to save energy and money [1]. Correctly determine and adjust the energy baseline for the estimation of the energy savings point is one of the main challenges and a potential crucial issue in the EPC due toThe thethird business model as itiscan generate a considerable of insecurity andissue monetary.
