Q

Environmental sustainability

A

rates of renewable resources harvest, pollution creation, and non-renewable resource depletion that can be continued indefinitely.
If they cannot be continued indefinitely then they are not sustainable
E.g. use of fossil fuels (oil, coal, gas)

any substance which may become harmful to people or buildings.
Corrosive, explosive, flammable, radioactive or toxic.
Typical sources;
chemical works, docklands, landfill/disposal, petrol station.

Clean up type;
1. Excavation, removal and disposal.
2. Limit spread
3. Treatment to Destroy, Remove or Detoxify.

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

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
Water Conservation;
Focus on 6 categories; cold & hot water supply, efficiency, sanitary, washing, food preparation
26
Energy Generation:
Sustainable energy can be: solar wind hydro geothermal biomass (natural fuel e.g. wood).
27
Solar photovoltaics:
PV panels are typically placed on roofs or unfarmed land
28
Solar thermal energy:
Energy from the sun is harvested to be used as heat for building systems
29
Geothermal energy
Natural heat energy stored in the earth itself. This can be used for electricity generation, space heating, hot water heating.
30
Ground source
heat pumps works by using the evaporation and condensing of a refrigerant to move heat from one place to another
31
Air-source
heat pumps extract heat from outside in a similar way to ground source heat pumps.
32
Tidal range:
The difference between high and low tide captured by turbine blades generate electricity.
33
Wave Power
As wind blows over the surface water the energy from the waves can captured by power turbines that generate electricity.
34
Wind power:
Wind can be converted into electricity by wind turbines whether on or offshore.
35
Biomass:
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
Organic waste:
Waste can be incinerated at 850C and the energy can be harvested for use as electricity or heat.
37
Energy conservation:
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
Life cycle costing; example
BUILDING COSTS ONLY Construction, maintenance, operational and disposal costs.
39
Whole life costing;
FULL FINANCIAL OVERVIEW - Includes Life Cycle costs PLUS Non-construction costs (design fees, land purchase, S106, finance etc), income, agency/marketing
40
Cost benefit analysis;
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
Carbon estimating; example of good vs bad
A carbon footprint is an estimate of the climate change impact of an activity.
42
Buildings/property vs the environment – Energy use;
Passive vs gas CHS
43
Land use; existing vs new
Green belt (untouched) vs brownfield (already in use)
44
Biodiversity;
Preserve existing wildlife e.g. butterfly mounds
45
Water;
Discharge (diesel, paint, chemical) from construction into nearby river or SW run off
46
Sustainable Materials;
wood, wool, stone Steel
47
Pollution;
Use of diesel engines, demolition
48
Waste minimisation;
Large quantities of material requiring disposal e.g. insulation, concrete, tiles
49
Design considerations – site; best approach to sustainability
Green vs brownfield
50
Design considerations building form;
solar gain
51
Design considerations materials; example
sustainable
52

use of natural light
53
