1
Q

What is buildability?

A

Refers to an item of the build and how easy it is to construct

The concept of buildability is an approach to architectural design which relates to the awareness of the designer for the method of construction of the building. It is the taking into consideration of the process of construction to a high degree in the construction of the building.

Q

What are the different types of ventilation systems?

A

Natural ventilation – openable windows etc.

Mixed mode ventilation – both natural and mechanical (openable windows + extract/supply or combination)

Q

Why is acoustic design important?

A

Building acoustics are not only important in reducing noise that may damage a person’s health, but they also help to promote effective transmission of different noises to ensure sound is transmitted and spread at optimal levels

18
Q

What is a db rating?

A

Sound is measured in units called decibels (dB). The higher the decibel level, the louder the noise.

19
Q

What is an asbestos survey?

A

An asbestos survey is a search for asbestos materials. An asbestos survey is a survey undertaken within a building, property, or structure, with the purpose of identifying asbestos-containing materials. Because asbestos fibres can’t be identified by eye, during an asbestos survey, samples may need to be taken

20
Q

What are the three main types of asbestos?

A
  • Chrysotile (white asbestos)
  • Amosite (brown asbestos)
  • Crocidolite (blue asbestos)
21
Q

Where should asbestos be disposed to?

A

Landfill site with asbestos permit

22
Q

Types of VRV Sytems?

A

Two pipes less flexible – can be switched from cooling to heating

Four pipe – can supply heat to one room and cooling to another

23
Q

What is a chilled beam system?

A

Passive chilled beams – Chilled water passes through the tubes cooling the rising hot air and chills the air causing it to descend back towards the floor

24
Q

What is superstructure?

A
  • All internal and external structure above the substructure
  • Usually everything above DPC
