Paper Abstract

In the building sector, some 300,000 buildings are destined for use as hotels. There are close to 13.7 million hotels rooms in the European Union, representing the highest percentage of energy consumption in the tertiary sector.
Many research papers have been written about the energy consumed in hotels in different regions and cities worldwide and when they are analysed, huge differences are revealed in the results obtained. The aim of this paper is to determine through the European Standard EN 15221-7 which energy consumption indicators for hotels can be more reliable and which factors can affect the dispersion of the results to carry out benchmarking to obtain comparable energy consumption data for hotels worldwide with similar features.
The method used is a benchmarking study of the energy consumption of six hotels located in warm clima based on four types of indicators, which provides useful information for developing new studies. The results show the energy consumption indicators according to five parameters: energy consumption indicator per total gross floor area (ECIGFA); energy consumption indicator per client (ECICLI); energy consumption indicator per net internal area rooms (ECINIAR) and energy consumption indicator per room (ECIR). One of the conclusions is that the indicators corresponding to net internal room area (ECINIAR) and room unit (ECIR) are more reliable than the index for total gross floor area (ECIGFA) and (ECICLI).

Corresponding author Biography

Jordi Castellano, CEO, LEED AP BD+C, BREEAM ES AP NC, BREEAM AP in use, BREEAM AP Homes, BREEAM ES AP Communities, VERDE AP NC, is the Director of Master’s Course in Sustainability and Facility Management in Tourism. As Director Jordi is responsible for organising all the aspects of the Course including: subject programming, selecting teachers, implementing arrangements between students and staff, coordinating projects.
Previously, Jordi worked for 4 years as part of the teaching team of the department of Architecture and Construction Engineering at Girona University. During this time he created the content of subjects for the Building Engineering Degree, e.g., Building Maintenance, Building Management, Building Assessment.
Before teaching, Jordi was a Facility Manager for CaixaBank. In this role he managed 235 offices located in different towns and cities in Catalonia. He was selected as the Building Director of another bank Caixa Girona, for which his principal function was to draw up the guidelines for new buildings and offices and manage all the facilities.
Later, Jordi founded two Engineering companies. The first is jc2managers ( Its principal aim is the project management of house building, industrial building, renovation and refurbishment. The second company is Green Building Management SL. ( Jordi provides sustainability solutions for buildings, and he is responsible for obtaining the Certification required, i.e. LEED, BREEAM and VERDE. One of the most important projects has been to draw up building sustainability guidelines for the German health insurance company, DKV.
Additionally, Jordi is a member of Green Building Council Spain (GBCe) and a member of the advisory Board of BREEAM Spain, and he was part of the Management Technical Advisory Group. This group revised the new BREEAM ES NC rating system. He has taught as a faculty member at Girona Professional Building Engineers College. He has also been an instructor at Barcelona Professional Architectural College, and has lectured at many conferences, seminars and workshops, such as the International Facility Management Council Spain (IFMA).
Jordi has published different papers in many international scientific journals, and he is a reviewer of scientific journals, e.g., Sustainable Cities and Society (SCS), Journal of Cleaner Production (JLCP), Dyna and he is guest editor for SAGE Open journal.
