Unit 103 - Lesson 3

Unit 103 - The Built Environment Life Cycle

Homes, places of work and all the other elements of the built environment that service the needs of society must be planned and constructed so as not to damage the environmental needs of future generations.

​

​Sustainability

Multiple Choice

What are fossil fuels?

• Fossil fuels are natural energy sources like coal, oil, and natural gas formed from ancient organic matter.
• Fossil fuels are renewable energy sources like wind and solar power.
• Fossil fuels are minerals extracted from the earth's crust for construction.
• Fossil fuels are synthetic materials created in laboratories for energy.

Constructing and operating a building uses significant amounts of energy, often referred to as a 'carbon footprint'.
This is because producing energy by burning fossil fuels introduces carbon into the atmosphere.

Poll

Who has heard of Climate Change?

• Yes

• No

Multiple Choice

What are renewable energy sources?

• Non-renewable energy sources like coal and oil.
• Energy sources that are artificially created and not sustainable.
• Energy sources that are only available in limited quantities.
• Renewable energy sources are energy sources that are naturally replenished, such as solar, wind, hydroelectric, geothermal, and biomass.

Multiple Choice

Which of the following is not a renewable energy source?

• Hydropower
• Fossil fuels
• Wind energy
• Solar energy

Match

• Wind

• Solar

• Hydro

• ASHP

• Ground Source

Turbines

Photovoltaic panels

Dams

Air Source Heat Pump

Geothermal heat pump

• Turbines

• Photovoltaic panels

• Dams

• Air Source Heat Pump

• Geothermal heat pump

​Renewable/sustainable energy sources

​Solar: solar panels work by absorbing sunlight with photovoltaic cells that generate direct current electricity that is converted to alternating current to be used in the home. 

Wind: wind turbines work by harnessing the energy from the wind turning the turbines blades; these are connected to a generator that produces electricity. 

Hydro: a hydro turbine works in a similar way to a wind turbine, but the energy is taken from moving water rather than wind. 

Air source: air source heat pumps work by absorbing heat from the air in a fluid and running it through a compressor, which increases the temperature of the water which can then be used to heat the home or as hot water. 

Ground source: these work the same as air source heat pumps, but in this case the heat is taken from pipes sank into the ground.

Energy usage in domestic dwellings

Open Ended

Write down as many ways as you can think of to reduce the amount of energy you use in your house:

​Insulation

​Energy use is significantly reduced through the use of insulation loft, brick cavity, ground floors, with slab or roll insulation and windows and doors with double/triple glazing, K glass and draught excluders.

​Specifications

​A specification is a written document that specifies certain details of the product being produced or assembled that cannot be shown via a drawing.

Examples include:​

The species of timber to be used​

The grade of timber to be used​

Fire rating

The type of glass that will be used​

The finish that is to be applied​

The quality of the workmanship.​

​Water is a natural resource, with limited availability. We pay large premiums for clean water to drink, wash and prepare food.

​

Water Conservation

Open Ended

List as many different ways you can save water in your homes:

​What is Grey or Rain Water Harvesting

​Look into :-

What is Grey / Rain Water Harvesting,
Give a short description on how and what this type of system can be found and used

​Waste water is collected from WHB, showers and baths. This is used to flush toilets, so drinking water is not used.

​​Grey water harvesting

Rainwater is collected and stored. This is used to flush toilets, so drinking water is not used.

​​Rain water recycling

​Wastewater management

​Pre-1920 properties had a mixed drainage system. Post-1920 properties have a split system with surface water going directly to a local water source and foul water been taken to the local treatment plant.​

​

It is illegal to deliberately mix foul with surface as it will pollute the local stream or rivers with human waste or chemicals.

Multiple Choice
