The 4-star Vincci The Mint hotel offers its guests an innovative concept from the moment they step through the doors into the reception area: from a check-in experience at the bar of its gastro pub, to its façade of great artistic value where the traditional architecture that dominates the exterior of the building contrasts with the originality of its interior design. Alternative, fresh, original, fun and full of unique spaces, Vincci The Mint offers a different style of accommodation in Madrid: a hotel in the city’s avantgarde Gran Vía with design by Jaime Beriestain. For the efficient production of domestic hot water (DHW), units from Japan’s Mitsubishi Heavy Industries were chosen, supplied by Lumelco.

The new hotel establishment embodies the latest commitment by the Vincci Hotels chain to restore historic buildings. The building was constructed between 1916 and 1919 and its f açade is of high artistic value, in which the traditional architecture that dominates the outside contrasts with the originality of its interior design. Property owner, Generali Group, has undertaken its renovation with an investment of approximately €5m.

Interior designer Jaime Beriestain was entrusted with the task of giving personality to the new establishment, respecting the spirit of the building while incorporating his particular style. Its surprising originality is evident when you walk through the door, with its mint green and turquoise hues forming the basis for the décor. Read more…

The four-star hotel Las Casas de El Arenal, situated in a refurbished 19th century building, is less than 10 minutes from the doors of Seville Cathedral and the Giralda tower. Decorated with close attention to detail, it has preserved the building’s high original ceilings. This hotel has recently been refurbished with the participation of CM4 Arquitectos as project managers, with Otaisa appointed as works supervisor. For the temperature control and domestic hot water production, units from Japanese brand Mitsubishi Heavy Industries were selected.

This project set out to give a new use to two 18th century Seville courtyard houses by refurbishing their structure and installations while respecting their inherent characteristics: the façades, patios and galleries as well as the relationship between floors and the original facing. The result is a hotel that has been effortlessly housed within a historic building, with no need to introduce elements that alter the original architecture.


The hotel Las Casas de El Arenal has 27 bedrooms distributed over three floors, fitted into the original spaces provided the dimensions and stability of the building so permitted. The bedrooms have coffered wood ceilings made using traditional timber framing methods. Restoration work was also carried out on the stairs, which feature Italian marble steps and elegant wrought iron and wood banisters. Read more…

To date, building certification standards have not taken into account the energy saving potential of every aspect relating to the automation and control of buildings’ energy consumption. The eu.bac methodology, based on currently applicable standards (EN 15232, DIN V 18599) and scientifically validated by the Technical University of Dresden (Germany), aims to fill this void. This article describes the success story of the hotel Pago del Olivo, demonstrating the savings potential that can be achieved in a building designed for hotel use following the application of this methodology.

Opened in January 2011, the hotel Pago del Olivo is a three-star establishment located in Simancas (Valladolid), offering 36 rooms, a 70 m2 lounge as well as indoor and outdoor car parking. Sedical undertook the certification, for which end an authorised inspector visited the establishment. Using a standard questionnaire, filled out by the owner, the person responsible for the building or the systems integrator, the authorised inspector checked to see if the stated functions were available and active.


Following a study of the documentation and the site inspection to check on the existence and type of control equipment, as well as ensuring it was working properly, the audit produced a score of 22 points with an E rating under the eu.bac system. The calculation tool also indicated that the installation had a margin for improvement of 78 points. Read more…

The Hotel Albir Playa Hotel & Spa is a beachfront hotel with 202 rooms that in 2014 looked into the need to refurbish its DHW installation. The refurbishment enjoyed the support of Driwergy, an ESCO that undertook a preliminary study of the hotel’s needs and suggested changing the diesel boilers to air/water aerothermal heat pumps. The solution proposed by Driwergy involved the installation of the Q-ton system from Mitsubishi Heavy Industries, a CO2 heat pump for DHW at up to 900C and that produces DHW at between 70 and 750C.

Firstly, the energy needs of the hotel for DHW production were studied. This not only took into account the heating up of the water but also losses from both the piping ring joints and the accumulation tanks. Having carried out the analysis, it was estimated that the hotel consumes 15,000 litres/day every month of the year, except for July and August in which consumption rises to 20,000 litres/day.

This resulted in an hourly consumption profile as shown in Figure 1, calculating an annual energy demand of 464,744 kWh. To cover this demand, two Q-ton units were selected, working in parallel, with a total accumulation of 18,000 litres. Read more…

Solutions for saving and comfort with the KNX automation system

Currently, one of the main concerns for businesses and hotel buildings managers is how to achieve an efficient use of electricity. And with good reason as, according to Eurostat, the costs of lighting and temperature control have increased in Europe by an average of almost 20% between 2006 and 2011, due to the disproportionate growth in global demand as well as political and market factors. The building’s manager is also affected by increasingly inflexible regulations regarding waste and inefficiency that are every day more focused on the residential and tertiary sectors with the latter, accord¬ing to the European Commission, being responsible in recent years for 41% of Europe’s total energy consumption.

Fortunately, for some years now it has been possible to find an appropriate response to these challenges thanks to KNX automation technology and consumption measurement and analysis devices that adapt to the savings needs of each property. This article explains how both interact and analyses the strategy to achieve the greatest saving possible in the hotel business.

To achieve the maximum saving, the first important factor is the awareness of the building’s occupants. In the residential sector, these individuals will take greater care as regards energy saving, as they are the ones that pay the bill. But in the tertiary sector (offices, hotels, etc.) raising the awareness of employees or guests regarding the rational use of energy is more complicated, as they are not responsible for the bills generated. The role of the buildings energy manager has existed for a short time. To achieve maximum effectiveness, the energy manager of the hotel has had to rely on technological tools that helped them undertake their work efficiently. The first step to saving energy in hotels is to have information on hand regarding the energy consumption at any time. Correct measurement leads to the possibility of taking immediate steps to correct imbalances and inefficient consumption habits thereby avoiding an over-inflated energy bill. Read more…

The Hotel TRH Ciudad de Baeza has undertaken the remodelling of its fan-coil heating and DHW production system by installing high performance condensing boilers from the manufacturer Ygnis. The incorporation of these boilers has a very positive impact on the performance of the heating and DHW production units, as demonstrated by the consumption results obtained after two full seasons in operation. As illustrated below, the reduction in consumption brings with it a significant reduction in the hotel’s energy bill. The economic impact is such that in the space of 1.5 years, the installation investment has been paid for, taking the six-month heating period as the basis for calculating the amortisation.

The hotel had two 4,000-litre tanks for DHW, heated by four electric resistance units of 18 kW each with a total output of 72 kW. These tanks used to supply the fan-coils circuit for heating and the DHW circuit. The existing installation was located in a basement, with little available space and no flue gas outlet, thereby preventing the installation of any type of boiler irrespective of the fuel used, unless a completely new boiler room was built.

The possibility of choosing renewable sources was dismissed because the peculiarities of the TRH hotel, an ancient 16th Century Carmelite convent next-door to the Church of the Hospital de la Concepción. Its location in the historic centre of Baeza, a UNESCO World Heritage city, made any structural reform to the building completely unfeasible. The lack of flat roofs and terraces meant that it was impossible to use the rooftop for the installation of solar panels. Nor was the option of using biomass viable due to the lack of space required for its management. Read more…

Optimising the energy installations of a hotel not only requires actions that involve the replacement of machinery. The first step for a large number of hotel establishments in Spain is to promote the change in the energy used for another less pollutant, more efficient source, that is of course more affordable. Following the sharp increases experienced in recent years in the price of diesel, one of the fuels proposed as an alternative is propane gas. The cost difference indicates that propane is both cheaper and cleaner as an energy source.

When comparing the efficiency of diesel and propane as a heating fuel, the latter is approximately 20% more efficient than diesel (specifically diesel C which is sold for heating). In addition higher levels of performance can be achieved with the installation of high efficiency boilers.

The installation cost of the propane tanks is lower than that of diesel units in addition to being less pollutant and easier to maintain. There are different types of propane gas tank, sunken or elevated, and each one has to comply with a series of conditions for its installation as well as requiring proper maintenance. Generally, their maintenance is the responsibility of the supplier, whether rented or if the client owns the property. Read more…

Air conditioning and temperature control systems, DOMESTIC HOT WATER (DHW) production, lighting, kitchens and room service, spas and meeting rooms…The way any area in a hotel works is connected to energy and water, in fact these two are so important that, in many cases energy consumption represents a hotel’s second biggest fixed cost, after the payroll.

This fact, which can be demonstrated in most of Spain’s commercial accommodation, has two implications for the hotel business: energy is an essential factor, but it is also an area in which there is room for manoeuvre to reduce costs, be more efficient, achieve greater sustainability levels and even provide greater comfort for guests.

Spanish hotels have been part of the trend in international tourism, supporting sustainability not only to improve and polish their positioning and branding, but bringing it in as a key part of their management strategy.
