distribute the warm air through the building, into the corridor, or into rooms at the other side of
the building, or wherever.
Saskia: So, we'd use presence detectors and heat sensors to regulate as many systems as
possible?
Roland: Yes. Well, that’s what we'd have with the maximum automation option.

c Match the words in the box to the synonyms (1 -5).
detect; detector; pick up; reading; regulate; set off; trigger;
1 sensor / detector
2 measurement /
3 control (adjust) /
4 sense / /
5 activate / /
d Complete the following extracts from the conversation by underlining the correct words.
Not just the usual systems that activate/detect the lights ...
We could use presence detectors to pick up/control other systems ...
... a presence detector sets off/senses that everyone's left a meeting room ...
... a temperature sensor picks up a positive detector/reading ...
...the sensor detects/regulates sunlight, and senses/triggers the blinds ...
... those sensors set off/sense a circulation system ...
...we'd use presence detectors and heat sensors to detect/regulate as many systems as possible?

e In pairs, describe the following automated systems using the words in Exercise 2d.
sensor parameter system
1 presence detector movement lights
2 smoke detector smoke fire alarm
3 thermostat room temperature electric convector heater
4 pressure plate weight of a person intruder alarm

3a 8.3 Roland and Saskia go on to discuss an alternative control system in the building.
Read the conversation and answer the following questions.
8 What assumption is the idea based on?
9 What design approach might be taken with regard to controls?
10 What is the advantage of this approach?

Roland: The second option is this. It's a very environmentally conscious company, so I assume
that green attitude is shared by all the staff. If that’s the case, why is there a need to automate
everything in the building when most things can be operated manually? Why doesn’t the boss
just circulate an email reminding people to switch the lights off when they go out and tell them to
lower the blinds when they leave a room in summer, so it helps the air-conditioning? I mean,
you’d save electricity, because you wouldn't need to control all the systems automatically, and
the money you saved by buying old-fashioned manual controls instead of hi-tech electronics
could be spent on planting trees or something. I mean, it sounds simple, but...
Saskia: Mm ... it's a very interesting idea. We have to bear in mind, of course, that the client's a
manufacturer of hi-tech electronic gizmos. I'm not sure how they'd feel about...
