A recent seminar hosted by ebm-papst discussed whether it was enough for companies to showcase their green credentials with solar panels.
The seminar focused on the energy savings that can be made in the hospitality sector.
The pros and cons of solar panels were analysed, with comparisons drawn between the energy savings that can be made from solar against other types of more efficient technology.
Malthouse Consultancy director Martin Evans said: “Businesses should not get distracted by ‘trendy’ ideas. The reality is that solar panels used in the hotel industry only contribute 1 per cent of energy, if you’re lucky.”
In contrast, ebm-papst has been a pacesetter for the less visible but ultra-efficient EC fan technology that can reap energy savings of up to 66 per cent compared with the 1 per cent by solar panels.
This is particularly relevant with regard to hotels, as research conducted by the Carbon Trust reveals that hotels have the highest cooling and ventilation CO2 emissions for the whole of the hospitality sector, with over 30 per cent of total emissions, more than double that of other sectors.
According to the research, the second highest source of carbon emissions for hotels comes from heating, which accounts for more than 20 per cent.
Ebm-papst has stated that a retrofit upgrade from AC to EC technology in heating, ventilation and air conditioning equipment can pay dividends for the hospitality sector.
On top of 66 per cent energy savings, additional savings can be made by utilising the EC fans’ built in control functionality, enabling fans to work at a very low level while rooms are not occupied, the company said.
Ebm-papst business development manager Robert Harness said: “In order to make essential energy savings, the hospitality sector needs to review the equipment that is producing the highest carbon emissions.
“Not only will upgrading from AC to EC fan technology achieve energy savings, businesses will also see a return on their investment within two years.”
