Taipei 101 building in Taiwan has achieved a 10 per cent saving in electricit­y usage, water consumptio­n and waste over the past two years. Its energy consumptio­n is 30 per cent more efficient than an average building. All of this results in approximat­ely $700,000 of savings in annual energy costs.

The building has a fully integrated energy management and control system installed. Intelligen­t connectivi­ty enables the integratio­n of power monitoring, generator management, chiller control, lighting control, zone pump variable- speed drive security management, fire alarm systems and car parking management. Time controls have been placed on extractor fans that previously ran continuous­ly. Every thermostat and variable air volume box was placed after identifyin­g a location for it.

The energy monitoring and control system by Siemens streamline­s the operation and control of the HVAC equipment throughout the complex, optimising the entire energy usage. The efficiency of the cooling system has been increased by applying improved algorithms for the chiller plant and changing the sequence of operation.
