Hotels

  • Electricity accounts for 60-70% of utility costs in a typical hotel
  • Electricity is a hotels second largest expense after staffing costs
  • Reputation is key to a hotels success

Reputation is particularly important in the hotel industry.  Hotels generally charge a premium for the promise, of a pleasant and even luxurious experience, with many operators guaranteeing this or your money back. 

Recently the hospitality industry has been under scrutiny for its outsized contributions to global carbon emissions.

With the rise of “ecotourism”, many operators are taking a proactive approach to reducing energy use, so that they can have a part of this market now worth circa $600 billion annually. 

For those not directly targeting “ecotourism”, energy reduction should still be a high priority, as it is more and more likely that there will be press about high energy use in this sector.  High emissions will only mean one thing – a bad reputation. With reputation being so important in this industry, it is only a matter of time before, high energy use will result in bad PR and loss of reputation.

The good news is that, energy use in hotels can often be hugely reduced, with solutions which pay back in short periods of time.

What if your hot water heating costs and resultant carbon could be eliminated?

What if your cooling costs and carbon could be cut in half?

What if by generating your own electricity on site you could cut your electric costs by 20-40%?

Manzana work with hotel operators to reduce energy costs and carbon.  We offer a free off charge site audit to identify quick pay back energy efficiency measures.

All solutions can be financed, meaning zero upfront investment.  We target solutions with 2-3 payback, that can be financed over 4-6 years, making it profitable from year 1.

For hotel operators who are more serious about energy reduction, we can help you develop a full energy transition strategy.  Working with our partners we can provide a number of funding options for energy transition projects:

Energy savings agreements – 0% investment or repayment.  Running cost savings shared between you and funder

Hire Purchase agreement – 0% upfront investment, repayments circa 50% of savings.  Equipment is your asset from day 1 attracting enhanced capital allowances.

Lease Purchase agreement – VAT paid upfront (20%), repayments circa 60% of savings.  Off balance sheet option.

You can of course purchase our solutions without finance.  After the 2 -3 year payback period, all savings are then yours!

We have many solutions to reduce energy use and running costs in hotels, here are some of our favourites:

 

What if your hot water heating costs could be eliminated?

What if your cooling costs could be cut in half?

What if you could generate enough electricity on site that you electric bill could be

Dependent on when and how your hot water, chilled water, blast fridges are used, all of these could potentially be achieved. Manzana work with food manufacturers to establish and deliver an Energy Strategy which will increase profits from year 1. In order for us to do this, we first assess your hour by hour gas and electrical usage. We will explore your plant control systems and understand current efficiencies and usage. From this we will create a bespoke Energy Strategy which can be financed with savings circa 50% of finance repayments.

Does this sound like the sort of future you wish for your children’s, children?

Low Global Warming Potential, No Refrigerant In Bedrooms Air Conditioning Systems

Do you have air conditioning in your hotel bedrooms?
Did you know that this is likely to be using up to 50% of the electricity used on site?
What if you could cut this by 50%? Are you concerned about using refrigerants in bedrooms? What if this fear could be eradicated?

Mitsubishi Electric HVRF systems use R32 low GWP (675) refrigerant, not only this, pipework which passes through bedrooms contains water instead of refrigerant, eliminating the need for refrigerant leak detection system in bedrooms. HVRF systems are up to 50% more efficient than old conventional air conditioning systems, often found in hotels.

Free Hot Water From Chiller Plant

Do you have a requirement for both chilled and hot water for domestic hot water/comfort cooling or/and for manufacturing process purposes? What if we could completely eradicate your heating cost? How much would you save?

Our dual energy heat pumps produce hot and chilled water simultaneously. In refrigeration, the by product of cooling is heat. In most manufacturing facilities, the heat from the cooling process is dissipated to outside atmosphere using fans on the condenser or via a dry air cooler. Dual energy heat pumps use C02 or R513a (HFO) refrigerant. The C02 variant is perfect for applications where you need large volumes of hot water up to 90 degrees and also have a cooling load. The dual fuel heat pump is installed on the return to the exiting chiller plant. By doing so, it acts as the lead chiller and while there is cooling load, produces free hot water for use in process or for domestic hot water purposes.

Generate Cooling During Off-Peak Times, Store & Use It When You need it

Cold Batteries are a product which can be used to store cooling energy. Cold batteries are made from various materials which are highly efficient in storing cooling. Storing cooling in cold batteries in comparison to storing in water, reduces volume by 2/3’s and so large amounts of energy can be stored in a relatively small space.

Why store cooling?

  • Chillers can be run at time that cheap (off-peak) electricity is available
  • Additional cooling can be stored for peak cooling requirements if plant is not big enough
  • By product cooling energy can be stored for when it is needed
  • Night-time noise restrictions can prohibit chillers being run, storage makes cooling available at these times

Low Carbon, Low cost electricity

Do you use lots of electricity on site?

Do you also have a constant demand for either chilled or hot water? What if you could produce low cost electricity onsite and as a bi-product produce chilled or hot water?

Combined Heat and Power (CHP) converts gas into both electricity and heat. CHPmaximises the fuel and converts it intoelectricity at around 35% efficiency andheat at around 50%. Heat is recovered fromthe engine by removal from the exhaust,water jacket and oil cooling circuits.

Typically a good CHP scheme can deliver anefficiency increase of anything up to 25%compared to the separate energy systemsit replaces.

The heat produced by the CHP engine, is often used for space heating or domestic hot water purposes. To make CHP work all, or the majority of the heat needs to be used. This is because the carbon free nature of the hot water produced by the CHP offsets the relatively high carbon content of the gas which is used to run the engine generator.

If there is insufficient heating load, the next consideration should be the cooling load on the site. The heat produced by the CHP engine can also be used to drive an absorption chiller (please see cooling section of this website), allowing the bi-product heat to be fully utilised to satisfy the site cooling demand.

15 years experience of low carbon technology

We have more than 20 years experience in mechanical and electrical Engineering. More than 15 years of this has been working with low carbon and renewable technology. We have had first-hand experience of thePro’s and con’s of various technologies through their life time. We have learnt what is required to provide solutions that deliver as intended.

03.

We tailor solutions to your business

Achieving energy, carbon emissions and running cost savings in commercial and industrial settings is far from a one size fits all situation. It is important to understand exactly how much cooling, heating and electricity you use, where and when waste heat/cooling is available and at what times during the day. As part of our free consultation we identify this and then design a scheme Which takes all of this into account.
