Q

The principles of material resource efficiency within the supply chain

A

MMC; Greater efficiency realised over the course of the project as elements are put together off site;
less wastage
construction requires less labour,
quicker
reduces H&S risks

23
Q

Sustainable materials

A

Don’t deplete natural resources or detrimentally impact the environment;
Bamboo,
Wood,
Wool,
Linen,
Straw,
Clay,
Stone,
Coconut.

24
Q

The principles of how design, technology and construction processes can contribute to sustainable building –

A

viewing the construction process holistically
e.g. BREEAM aids sustainable building by considering not just post completion efficiency but construction processes
and supply chain.

25
Q

Water Conservation;

A

Focus on 6 categories;
cold & hot water supply,
efficiency,
sanitary,
washing,
food preparation

26
Q

Energy Generation:

A

Sustainable energy can be:
solar
wind
hydro
geothermal
biomass (natural fuel e.g. wood).

27
Q

Solar photovoltaics:

A

PV panels are typically placed on roofs or unfarmed land

28
Q

Solar thermal energy:

A

Energy from the sun is harvested to be used as heat for building systems

29
Q

Geothermal energy

A

Natural heat energy stored in the earth itself.
This can be used for electricity generation,
space heating,
hot water heating.

30
Q

Ground source

A

heat pumps works by using the evaporation and condensing of a refrigerant to move heat from one place to another

31
Q

Air-source

A

heat pumps extract heat from outside in a similar way to ground source heat pumps.

32
Q

Tidal range:

A

The difference between high and low tide
captured by turbine blades
generate electricity.

33
Q

Wave Power

A

As wind blows over the surface water
the energy from the waves can
captured by power turbines that generate electricity.

34
Q

Wind power:

A

Wind can be converted into electricity
by wind turbines
whether on or offshore.

35
Q

Biomass:

A

Organic materials that can be used as fuels.
Biomass can be replaced relatively quickly.
They are used in the form of pellets
burned in boilers as a heating source.

36
Q

Organic waste:

A

Waste can be incinerated at 850C and the
energy can be harvested for
use as electricity or heat.

37
Q

Energy conservation:

A

In passive solar building design,
windows, walls, and floors
made to collect, store, and distribute solar energy in the
form of heat in the winter and
reject solar heat in the summer.
It does not involve the use of mechanical and electrical devices.

38
Q

Life cycle costing; example

A

BUILDING COSTS ONLY
Construction,
maintenance,
operational and
disposal costs.

39
Q

Whole life costing;

A

FULL FINANCIAL OVERVIEW -
Includes Life Cycle costs
PLUS Non-construction costs
(design fees, land purchase, S106, finance etc),
income,
agency/marketing

40
Q

Cost benefit analysis;

A

reviews the value/equity/income against the cost from the proposal and
whether the outcome is commercially viable.
From a sustainability perspective the change in materials and cost of fitting may not be able to be justified.

41
Q

Carbon estimating; example of good vs bad

A

A carbon footprint is an estimate
of the climate change impact of an activity.

42
Q

Buildings/property vs the environment – Energy use;

A

Passive vs gas CHS

43
Q

Land use; existing vs new

A

Green belt (untouched) vs
brownfield (already in use)

44
Q

Biodiversity;

A

Preserve existing wildlife e.g. butterfly mounds

45
Q

Water;

A

Discharge (diesel, paint, chemical)
from construction into nearby river or SW run off

46
Q

Sustainable Materials;

A

wood,
wool,
stone
Steel

47
Q

Pollution;

A

Use of diesel engines, demolition

48
Q

Waste minimisation;

A

Large quantities of material requiring disposal
e.g. insulation,
concrete,
tiles

49
Q

Design considerations – site; best approach to sustainability

A

Green vs brownfield

50
Q

Design considerations building form;

A

solar gain

51
Q

Design considerations materials; example

A

sustainable

52
Q

Design considerations lighting;

A

use of natural light

53
Q

A

natural through aligning building with prevailing wind

54
Q

Design considerations heating;

A
