Introduction

The ibis Novena Hotel Singapore was awarded a Green Mark Platinum Award by the Building Construction Authority of Singapore in March 2015. It is an international 3 star, 10-storey, 241 room hotel completed in April 2011. It sits on four contiguous freehold sites located in the heritage-rich Balestier and Novena area. The hotel is within ten minutes' walk to Novena MRT station, just six stations away from the Central Business District in Raffles Place and two stations away from the main shopping district at Orchard Road.

Green features and sustainable technologies

AIR CONDITIONING SYSTEM RETROFITTING

Conversion of air cooled Variable Refrigerant Volume (VRV) system to centralised water cooled refrigeration system to achieve efficiency of 0.67 kW/RT with estimated reduction of energy consumption at 848,985 kWh/year (about 33% reduction). Heat Recovery For Water Heating - Installed new hot water recovery system from centralised refrigeration system to isolate electric calorifier.

INDOOR AIR QUALITY

Improved fresh air ventilation and improved indoor air quality via controlling and treating the fresh air inlet and returned air from the AC system. Improve Lighting Efficiency - Extensive lighting replacement including hotel rooms to achieve estimated 42% better efficiency after retrofitting.

WATER CONSUMPTION AND EXTENSIVE RECYCLING

Retrofitted with water efficient appliances and implemented the Planet 21 program, an Accor hotel program for sustainable development. Among the initiatives, to encourage hotel guests to reuse their towels instead of washing after every use.

For every 5 reused towels, we undertake to plant 1 tree in Indonesia or Thailand that will not only create employment but also reduce greenhouse gas emissions.

Other notable green features

Apart from retrofitting the air-cooled VRV air- conditioning system to a water-cooled system, other sustainability initiatives such as using the heat generated from the cooling tower to preheat the hot water supply to the guest rooms was implemented.

Also as part of the on-going green initiatives, the hotel will upgrade to energy saving LED lightings in phases and improve the air quality in the building by controlling the fresh air inlet. The LED lightings reduced the energy consumption significantly.

Measurable results
  • Estimated savings in electrical consumption with a 33% usage reduction per annum
  • Greenhouse gas emission reduction of about 425 tonnes CO2 per annum, about 30% of the total carbon emission

Costs and benefits

Savings are estimated to be in the region of SGD 500,000 (USD 360,000) with a payback period of 2.5 to 3 years on capital expenditure, depending on consumption.
