In any type of installation, and especially those destined for the hotel sector, the reduction in the space utilised to install heating and DHW units is a variable that could be a significant factor, particularly in refurbished installations. Focusing on installations for the hotel sector, any space that can be reduced for the installation of the boiler room could be allocated to other uses that enable new business lines and sources of revenue (parking spaces, roof terraces, etc….). Traditionally, the DHW installation has been characterised by requiring a large space for positioning its associated units, in particular, the accumulation tanks.

It is well known that one of the main energy demands in a hotel-type installation is the need to cover the domestic hot water (DHW) service expected by the clients of such establishments. This service is moreover a priority, as its lack of availability could impair the image of the hotel as well as result in a possible loss of clients.

 

To avoid this, hotels have historically resorted to the design of installations with large tanks of storage water, in order to have a volume of water readily available that is able to cover consumption peaks as they occur. This design criteria is sufficient to guarantee the right level of comfort and customer service, but can raise questions today in terms of energy saving and the space necessary for its installation.

The expert vision of a company focused on reducing energy consumption

The hotel sector is currently enjoying a significant upsurge thanks to the strong recovery being experienced by tourism. There are many newly constructed hotels, but also a large number of renovations. The sector is increasingly more demanding and hotels have to modernise. They also have to be more competitive and this undoubtedly translates into a control of operational costs where the reduction in energy expenditure plays a vital role. Jung is particularly focused on energy efficiency solutions, offering a wide range of options and with emblematic projects already undertaken that improve energy efficiency in this sector.

Jung has spent many years offering energy saving solutions to the market, in particular the tertiary sector. There is nothing new about energy efficiency. Jung’s solutions aim to reduce consumption in lighting and temperature control – the two concepts that consume the most energy in any building, including hotels.

 

First, there is energy saving in the bedrooms. Jung offers the possibility of adapting bedroom temperatures to the circumstances of any given moment. Remember that for every degree by which the temperature increases from heating or reduces from air conditioning, 7% more energy is being consumed. Another issue is lighting control. Jung’s systems prevent the lights from staying on when the client walks out of the bedroom. They also provide the user with an optimised use of the lighting by configuring settings or centralised switches via sensors located next to the bed.

Since 26 September 2015, the Ecodesign ErP Directive has been of compulsory application for EU Member States as regards the design of Energy-related Products (ErP) and as from its entry into force only those products manufactured according to the ErP requirements can be sold with the EC label. Although this directive affects over 1,000 product categories, for those relating to HVAC and DHW production, it covers boilers, heat pumps, accumulators, cogeneration systems, combined products systems, establishing their minimum efficiency levels, the maximum levels of NOX emissions, the minimum insulation for accumulators and the maximum level of acoustic emissions for heat pumps.

Heating and combi boilers that have had to comply with the ecodesign requirements since September 2015 include those with outputs of up to 400 kW, for which the standard has defined a minimum energy efficiency level to be complied with. This means that the new ErP Directive will prevent the sale of less efficient heating and combi boilers that do not meet the minimum performance requirements indicated in the Directive. In practice, this means that the market will tend towards condensing boilers which are almost the only type that can achieve the minimum requirements established by the ErP.

Another substantial change introduced by the Ecodesign Directive is that performance for the boilers that until now has been defined on the basis of the LCV (Low Calorific Value) will now be defined based on the HCV (High Calorific Value).. Read more…

Following the sharp increases in the price of energy over the last six years and the increasingly widespread incorporation of installations that offer added value to the establishment but which increase its energy expenditure (spas, swimming pools, gymnasiums, etc.), the hotel sector today is aware of the significance of energy as part of its operating costs. Proof of this is that fact that a large proportion of hotels have undertaken, or are considering carrying out, some form of measure to improve energy efficiency.

However a very large number of establishments lack knowledge and information regarding the energy consumption generated, which prevents the development of energy efficiency improvement measures and reductions in consumption with the sufficient technical solvency and the possibility of measuring and verifying the sought-after savings.

It is very important that the hotel owner improves their knowledge in terms of when, how, where and how much energy is consumed by the facilities of each hotel, as in this way they will have access to very valuable information to aid the decisionmaking process on the improvement measures to be carried out, offering a real tool to subsequently verify their effectiveness.

Forming part of the Conferences on Sustainability and Energy Efficiency in the Hotel Sector 2014 organised by ITH, the Spanish Hotel Technological Institute, the fourth event of this type in 2014 took place in Tenerife and, as with previous conferences, FuturENERGY was there to distribute our magazine to speakers and attendees.

What does the integrated energy management of my hotel involve?
How can I optimise DHW production and temperature control?
What does energy certification mean for a hotel establishment?

During this participatory session, the main players involved in the process set out their perspectives, providing attendees with in-depth information on the concept of integrated energy management and its different energy services models. The conference was aimed at designing the optimal solution for each project to maximise the achievement of energy saving in the hotel’s temperature control and DHW production installations. Such saving translates into guaranteeing results and the reduction in both the maintenance and operation costs of the equipment installed with minimum or no investment required.

The conference also discussed a very topical issue: the energy certification of buildings, its resultant implications and benefits with a view to guaranteeing savings based on Energy Saving Measures, in addition to the importance of carrying out energy audits as an instrument to legalise all the installations in line with the new regulations. In addition it identified the role of the financial entities necessary to guarantee and adapt the application of financing models for the proposed technologies and services to the hotel sector.
