This publication informs the hotel industry about environmentally, climate and ozone friendly technologies for Refrigeration and Air Conditioning (RAC) devices. Most of the green alternatives presented here are already available in several countries. By “green” technology, it is referred to devices or appliances that have zero impact on the ozone layer, ultra-low or zero Global Warming Potential (GWP below 10) and are also highly energy efficient.
This guide aims to provide insights into which technologies are appropriate for which types of applications, taking into account system capabilities, final application, and other relevant considerations. The publication aims to show the way to achieve a large part of the decarbonization of this sector and the benefits of being carbon neutral organizations. It shows the influence of these technologies in the marketing of the organization, the decrease of energy costs and their compliance with respective national and international policies that will mark the future of the RAC sector in the tourism industry.
This publication is based on a previous publication on the RAC sector in the hotel industry in Costa Rica (Ouvrira une nouvelle fenêtre), dated August 2021, by the IKI project “Cool Contributions fighting Climate Change (C4)” and the EU/BMZ Project Sustainable and climate-friendly Phase-out of Ozone Depleting Substances (SPODS)”, therefore numerous best practice examples of green RAC equipment from Costa Rica as well as specific country-based values (e.g. electricity costs/mix) are used for this publication.
For further information about Green Cooling in the Hotel Industry we recommend the Green Cooling Roadmap for the Jetwing Hotel Group in Sri Lanka (Ouvrira une nouvelle fenêtre), published in 2017, by the IKI project "Green Cooling Initiative (GCI)". The Green Cooling Initiative has analysed RAC equipment and management in ten entities of the Jetwing Hotel Group. Based on current equipment and a calculated business-as-usual (BAU) scenario, a set of four key GHG mitigation strategies have been proposed.
