In order to provide a comfortable and healthy indoor environment the building mechanical system must:
?
Provide an acceptable level of temperature and humidity and safe guard against odours and indoor air pollutants.
?
Create a sense of habitability through air movement, ventilation and slight temperature variation.
?
Allow the occupant to control and modify conditions to suit individual preferences.
Resistance to building management systems and intelligent buildings technology
?
\buildings are already energy-efficient.\(Is the whole building energy-efficient, or is the landlord limiting his focus to common areas and gross leased spaces?)
?
\out tenant space.\(Does the specifier have any idea who will bear the increased operating costs of such a strategy?)
?
\need a two-year simple payback or less.\(Is this still realistic, given that the percentage return on money markets is literally one-tenth what it was 20 years ago?)
?
\tenants really pay all energy or just the energy over a pre-set base year or expense stop?)
?
\selling the building.\(Should we assume then that lowering the operating expenses and reaping the increased asset value are not important?)
Intelligent homes
Building management systems for residential applications
外文文献翻译
With the widespread adoption of digital technologies there will be a profound change in how we communicate with others. Even how, in our homes, we shop for goods and services, receive news, manage our finances, learn about the world, and, conduct business, manage resources, find entertainment, and maintain independence and autonomy as we enter old age.
These activities increasingly take place in the home. As our perception of banks, shops, universities, communities, and cities change in response to new technologies, so home building management systems are taking on an extraordinary new importance.
As it exists today the home cannot meet these demands or take advantage of new opportunities created by social and technological changes. Most people live in spaces poorly tailored to their needs.
Until recently, the majority of homes were wired with little more than the main electrical circuits, a few phone lines, and a few TV cables. Times have changed. Electrical and security system contractors routinely install low voltage communication network cables for a wide range of intelligent home or 'smart home' systems.
Services and equipment that utilise these networks include: security; home theatre and entertainment; telephones, door-phones and intercoms; PC and internet networks; surveillance cameras; driveway vehicle sensors; communicating thermostats; motorized window blinds and curtains; entry systems; and irrigation systems. Smart homes
'Smart home' is an alternative term for an intelligent residential building, or an intelligent home. A few years ago these concepts weer considered futuristic and fanciful. Now they are reality. These terms are

now commonly used to define a residence that uses a control system to integrate the residence's various automation systems.
Integrating the home systems allows them to communicate with one another through the control system, thereby enabling single button and voice control of the various home systems simultaneously, in pre-programmed scenarios or operating modes.
The development of smart home systems focus on how the home and its related technologies, products, and services should evolve to best meet the opportunities and challenges of the future. The possibilities and permutations are endless. Here are some examples: Smart home example scenario 1
A scenario such as 'I'm Home' could be triggered by pressing one button on a key-ring remote-control from your vehicle as you approach the driveway. The control system receives the key-ring remote-control's command. This will then trigger a pre-programmed sequence of functions. For example starting by turning on the lighting in the driveway, garage, hallway, and kitchen. It then disarms the security system, opens the garage door, unlocks the interior garage entry door, adjusts the heating to a preset temperature, and turns on the whole-house audio system playing your favourite cd, whilst drawing you a bath.
The control system is programmed to meet specific user requirements, initiating sequential automatic operation of the home systems, in response to 'one button' commands based on the situation and or time. Smart home example scenario 2
外文文献翻译
At 7:30am and you awake to the sound of your favourite cd playing in the background; the lights in your bedroom switch on; 'fading up' to allow you to wake up in your own time. The downstairs intruder alarm system is de-activated. In the kitchen the coffee machine turns on to make a drink. The ground floor curtains and blinds open; the towel heater in the bathroom warms the towels. And you haven't even got up yet.
