Where next for the smart home? T

he first general purpose smart home technology, X10, was developed in Scotland in 1975. It remains widely available today. Since then, second and third generation smart homes have arrived. George Chan Tsz-chung looks at the benefits are and where we headed next. Leaning over the railing of The Peak Tower rooftop at night, I indulge myself: Mother Nature, night birds and insects tweeting and buzzing; a delicate fragrance of blossom with a hint of aromatic oak wafting by on a breeze that caresses my cheek … … and then laser beams slash ruthlessly through the tranquillity and I realize that the Symphony of Light across Victoria Harbour has begun. Looking down on glittering skyscrapers and the hustle and bustle of lives, streets and vehicles, it is clear that the energy of Hong Kong offers zero down time. For decades, the metropolis of Hong Kong has been praised worldwide for its vibrancy and its continued stability and prosperity.

digital society, the “smart home” concept has become widely accepted because it allows wiser use of energy through an energy management system (EMS). A good EMS manages the complexities of energy consumption and systems in a building so that it uses less energy, is more comfortable and easier to operate. It does this by logging and analysing key data from electricity, gas and water systems in real time and integrating archived internal data with monitored external data such as weather information. Analytical tools allow users to optimize its operation and make sensible decisions about energy consumption from anywhere with an internet connection. Take air conditioning, for example. A quarter of Hong Kong’s residential energy consumption is by air conditioners. With the aid of the automatic control enabled by an EMS, smart homes will adjust air conditioner settings, such as changing the temperature set-point
