This thesis paper was written by Eric Joseph Urban at Appalachian State University. It concerns how to properly model hot water consumption in hotel lodgings in order to accurately optimize solar thermal installations.

The “Collective Prosol Programme” in Tunisia is gaining momentum. The National Agency for Energy Conservation (ANME) started the subsidy programme for solar thermal installations in the tertiary sector back in 2008. The application rate was low at first, but 2010 became a good year for the commercial solar thermal market. At the end of that year, ANME counted a total installed and subsidised collector area of 4,000 m², including four hotel installations with together 480 m² and around 130 smaller installations under 30 m². According to ANME, grants for another 1,770 m² are still in the pipeline. And, a solar programme targeting 18 public swimming pools is also under development.

This case study was written by the Canadian Solar Industries Association (CanSIA). It examines the case of Penticton's Hostel in British Columbia, Canada, which installed solar water heating for its hospitality operations.

Over the last 5 years, the number of installed solar cooling systems worldwide increased tenfold. The main obstacles for a more pervasive and faster market development are high upfront costs and lack of experience among main stakeholders, such as planners and architects. Based on various simulations, German institute Fraunhofer ISE analysed the saved primary energy and total annual costs of solar thermal, photovoltaic and conventional solutions for heating and cooling by using the example of a hotel in Madrid (see attached presentation).

Since the beginning of 2011, solar cooling technology from Thuringia/Germany ensures a pleasant indoor climate in the rooms of the eco-hotel Pousada do Parque in Cuiabá, Brazil. On 15 January, the pilot plant came into operation, and since then, it has not only provided cold water, but also important input for a current campaign to accelerate the use of solar cooling technology in the Brazilian hotel sector.

Solar accommodation: The Ginger hotel chain, which is part of Indian Hotels Company Limited (IHCL), takes its commitment to energy-efficiency very seriously. In the future, all chain hotels are going to have a solar water heater installed on their roof.

The marketing campaign for solar hot water systems in the residential sector in Mexico, Procalsol (2007 to 2012), bore fruit: According to the annual market statistics of the National Association of Solar Energy (ANES), the newly installed collector area in households almost tripled from 53,183 m² in 2008 to 132,934 m² last year.

Turkish solar thermal manufacturers increasingly establish separate companies to handle hotel installations or process heat applications. Photo: Ina Röpcke

Looking at the future development of the Indian solar thermal sector: The figures above show the most realistic scenario by New Delhi based consultancy Greentech Knowledge Solutions. The residential market will also dominate in the years to come, still retaining a market share of around 80%.
