Here's an interesting article we read recently about Sudima Auckland Airport Hotel, who achieved carbon neutral status last year by measuring its greenhouse gas emissions through the internationally accredited programme in accordance with the ISO standard for reporting greenhouse gas emissions and removals, and by taking the additional step to put in reduction plans and offset all remaining emissions.

The hotel has a Qualmark rating of 4.5 and consistently operates near full capacity.

Sudima have achieved this by a fine attention to detail, and some interesting features.

"Our chilled beam air-conditioning system is the first in the whole of the Southern Hemisphere. It heats and cools the room using convection currents created by hot and cold water. This means the chilled beam component in the room has no fans but still provides considerably more fresh air than is available in most other hotel rooms,"

No in-room refridgerators - "The hotel still offers a full range of in-room dining with fresh food made in-house from our restaurant, available 24 hours a day. Our all day menu covers a range of drinks and multi-cuisine food prepared by our excellent chefs. If the need arises, in-room refrigerators are available on request.
