Novotel Sydney Central – Ozone Technologies

Located in the heart of Sydney with a 120 year old history, the Novotel Sydney Central is at the forefront of its industry when it comes to savings in its on premise laundry operation.

The heritage-listed, low rise, historic sandstone building lends an air of old world charm and traditional style combined with modern chic which is reflected in its accommodation, personalised service and dining options. With energy issues on everyone’s mind, it’s worth highlighting that Novotel Sydney Central expects to derive potential monthly savings (based on current figures) of 55% following the utilisation of the OTEK system earlier this year. The usage of the OTEK system complements Citigate Central’s NABERS Hotel Energy and Hotel Water Ratings certification where it was awarded 2 star for energy and 2.5 stars for water which is considered, in industry terms to be an excellent achievement. Indeed,the NABERS rating plays an important role in the hotel’s sustainability management plan. Edi Buffon, Chief Engineer at Citigate Hotel, saw a need and a desire to improve the hotel’s laundry operations and soon realised that by reducing the labour time factor associated with each linen wash was but one important element in cutting the bottom-line costs.Ozone Technologies was on hand every step of the way of the OTEK system trial phase to answer any questions concerning the technical nature of the installation and diligently guide Citigate’s management through each aspect of the testing procedures. The trial period involved taking daily readings along with constant monitoring of the impacts of the OTEK system on water and energy as part of the data collection activity. Once the latter activity concluded, management was able to make a calculation of the cost savings.

The Ozone Technologies system allows the hotel to useless chemicals, less water and less energy in their operation. As an example, the OTEK cycle time for sheets and towels is now 35 minutes compared to the previous wash cycle time of 59-62 minutes – a very significant productivity saving. According to Edi Buffon:

“Housekeeper work time can now be focused on other important aspects of the daily workload, thus making it a ‘win-win’ for both management and staff. Our laundry operation is relatively large consisting of 4 washers and 3 dryers, so it makes sense to maximise the throughput of each load. It appears the OTEK system will prove signifcant in the long run for our hotel’s operating costs.”

The Potential Savings on monthly washer operating hours at the Novotel Sydney Central are as follows:

  • Productivity Hours: Savings 792 hours = 58%
  • Monthly Cost Per Kg Savings: $2788.30 = 55%
  • Potential Monthly Savings on Dryer Operating Hours: 53 hours = 22%Potential
  • Monthly Water Savings: 4425 kls = 36%
  • Annual Summary of Savings on Labour & Utilities: $35,483.42 = 59%
