Describing automated systems
8.2 In pairs, discuss the difference between an automated and a manual system. What do you think a Building Management System (BMS) does in intelligent buildings? Suggest some operations that can be monitored and controlled automatically by the BMS in large buildings such as offices.
8.3 Ω Roland, a mechanical and electrical services (M&E) engineer, is talking to Saskia, an architect, about the design of a new building. Listen to the conversation and answer the following questions.
What is a key characteristic of the client company? How will this characteristic affect the building design? What do you think is meant by presence detectors? What does Roland say about design options and how does he describe option one?
8.4 Ω Roland gives some examples of sensors and controls. Listen to the next part of the conversation and tick (∨) the points he mentions.
1 | controlling the electric lighting inside the building |
2 | controlling the amount of solar radiation entering the building |
3 | controlling the air flowing in and out through the windows of the building |
4 | controlling the flow of warm and cool air around the interior of the building |
8.5 Match the words in the box to the synonyms (1-5).
detect | detector | pick up | reading | regulate | set off | trigger |
sensor / detector measurement/ __________ control (adjust) / ___________ sense / ____________ activate /_____________
8.6 Complete the following extracts from the conversation by underlining the correct words.
1. Not just the usual systems that activate/detect the lights...
2. We could use presence detectors to pick up/control other systems...
3. ... о presence detector sets off/senses that everyone's left a meeting room...
4. ... a temperature sensor picks up a positive detector/reading...
5. ... the sensor detects/regulates sunlight, and senses/triggers the blinds...
6. ... those sensors set off/sense a circulation system...
7. ...we'd use presence detectors and heat sensors to detect/regulate as many systems as possible?
8.7 In pairs, describe the following automated systems using the words in
Exercise 8.6
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 |
8.8 Ω Roland and Saskia go on to discuss an alternative control system in the building. Listen to the conversation and answer the following questions.
What assumption is the idea based on? What design approach might be taken with regard to controls? What is the advantage of this approach?8.9 You are in the M&E design team for the new building project and have received the following email from the project engineer asking for your input. Read the email and, in pairs, discuss what the engineer wants you to do.
To: Lauren Harvey
Subiect: Presence detectors
Could you look into the practicalities of using presence detectors for controlling the lights in different parts of the building? We'll probably have a mixture of detector-controlled systems and manual switches. The question is, which type of control do we want to have in each location? (Please see my list below.) A critical issue will be setting the switch-off delay in different locations, i. e. how long the lights remain on after the last movement is detected. On my last project, we had a lot of complaints from the client about the lights going off while people were still in rooms. So can you think about different timer delays for different locations in the building?
