Unit 32:Sustainable Buildings
Scenario
The use of sustainable materials and building methods is a growing area in construction. The design of
our buildings is changing to incorporate sustainable methods that help to reduce the possible impact of
global warming on the environment.
The ultimate goal in sustainable buildings is the zero carbon home – a structure that is built and run
without producing any greenhouse gases. This is the future of sustainable contruction.

Unit 32 Learning OutcomesError! Reference source not found.
LO 1. Understand the application of sustainability on the built environment
LO 2. Understand how sustainability benefits our built environment
LO 3 Know how sustainable design and construction improves our built
environment
Unit content covered by assignment:
1 Understand the application of sustainability on the built environment
Sustainable methods: methods eg sustainable communities, infrastructure, building
orientation, use of natural light and heat, timber-framed construction, modular construction,
prefabrication of homes, forming community spaces
2
Understand how sustainability benefits our built environment
Application: of techniques eg reduction in heat loss, high levels of insulation, heat recovery
systems, rain water harvesting, grey water systems, reed bed sanitation schemes, swales,
irrigation ponds, small wind turbine technology, ground source heating
3
Know how sustainable design and construction improves our built environment
Sustainable design features: for buildings eg use of glass walls, surface areas, building
density, building orientation, use of brownfield sites, maximum use of footprint, earth
berms, grass roof construction, alternative energy sources, indoor gardens
Sustainable materials: in buildings eg use of sustainable certified sources, timber, oak-framed
structures, natural insulation materials, hemp, wool, external timber cladding,
recycled materials, crushed demolition waste, timber, bricks, natural products, slate, stone,
straw

Task 1 (AC 1.1)
The following sustainable methods are going to be used on a new house design for a “Grand
Designs” TV program. Explain their use.


Turning a building to face south
Prefabrication of a home
You need to look at what affect each of these will have in sustainable terms and explain how each
of these techniques can contribute to saving energy and resources
Task 2 (AC 1.2)
The following sustainable methods have been employed on a building. Evaluate their use describing
the advantages and disadvantages of each method used.

Heat recovery systems

Rain water harvesting

Reed bed sanitation schemes
Evaluate means discuss critically the use of these methods providing the advantages and
disadvantages of each by undertaking some research
Task 3 (AC 2.1)
The local environment action group has asked for your help with an objection to a local planning
application on a green field site. The three techniques above are going to be used on the scheme
and you have been asked to answer the following question
Explain how the application of the three sustainable building techniques will protect the
environment
The key word here is protection. It is this word that you need to explain in terms of how each key
method protects our environment from harm and damage
Task 4 (AC 3.1)
Further to the work you have undertaken for the environmental action group, the designer on the
new development has asked if you could produce the following
A fully illustrated sustainable design feature for a building on the scheme
You could do this by producing a drawing or sketch that is your own work and then annotating it
with descriptions

Sustainable Buildings
Sustainability
Task 5 (AC 3.2)
The head designer on the new development has proposed that the following sustainable materials
should be used within the new scheme. For each of the following identify their use within a building
1.
2.
3.
4.
5.
oak
sheep’s wool
hemp
crushed demolition waste
straw
You will need to undertake some research and establish where each can be used within a building to
help you identify where each material would usually be found in a building.
Tutor Information
The assignment brief will need to be delivered within an assessment tutorial so the level of the
learners is catered for in a full understanding of what is required to be presented as evidence for
each assessment criteria. The key evidence presented must meet the short criteria that has been
written into the end of each task as this is the criteria taken from the specification.
Access to IT facilities to undertake some research is required.
A range of sustainable material examples would be useful to examine by learners.
Guest speakers from material suppliers would provide an excellent method of engagement.
