Study Notes
Unit 103: Environmental and Sustainability Measures in Domestic Dwellings
- Learning Outcome 2: Know the applications of energy sources in domestic dwellings
Applications of Energy Sources
-
Many different energy types are used in domestic dwellings
-
Some energy sources produce high carbon emissions, others produce less
-
Responsibility to reduce carbon footprint within the dwelling
-
Work out carbon footprint using the Energy Saving Trust's online calculator:
http://carboncalculator.direct.gov.uk/index.html
High Carbon Producers
-
Fossil fuels are high carbon producers
-
When burned, they produce carbon dioxide (CO2) and water vapor
-
CO2 is a damaging greenhouse gas, emitted by power stations, boilers, and fires
-
All fossil fuels are non-renewable energy sources
-
Examples:
- Solid fuel: Coal, coke, and peat
- Oils: Fuel oil and petrol
- Gases: Natural gas and LPG
- Electricity: Produced from non-renewable sources
Low Carbon Producers
- These are fuels made from renewable sources, but use another fuel to power the system
- Examples of technologies: Pumps, electronic valves, timers, programmers that use electricity
- May require backup systems
Solar Thermal
- Uses solar heat to generate domestic hot water
- Diagram of system components included
Biomass
- Uses pellets from plant and animal matter that are burned to produce heat
- Diagram of biomass system components
Heat Pumps
- Machines used to heat or cool buildings by moving heat from low to high temperature reservoirs
- Diagram of system
Combined Heat and Power (CHP)
- Can use various fuels, but attempts to extract every available bit of heat
- Can be used for single properties or district systems
- Diagram of system
Zero Carbon Producers
- Net carbon dioxide emissions from system are zero
- Classified as renewable energy systems
- Increasingly common due to their "green" status
Wind Generation
- Systems use wind speed to turn turbines, producing electricity
- Higher wind velocity results in faster blades and more electricity
- Common type: horizontal axis generator; vertical axis generators also exist
Tidal Generation
- Harnessing the power of the rise and fall of sea levels for electricity generation
- Multiple methods for harnessing tidal power
- Diagram provided
Hydroelectric Generation
- Uses water head height to drive turbines, generating electricity
- Can utilize fast-flowing rivers or commonly dams for water head
- Diagram of a hydroelectric dam included
Solar Photovoltaic (PV)
- PV cells mounted on roofs to collect direct current (DC) power
- DC power is converted to alternating current (AC) for use in homes
- PV farms also exist in the UK
Reducing Carbon Emissions
- Governments have formed agreements to reduce carbon emissions from buildings
- Reduction plans are implemented to mitigate global warming and ozone layer depletion
- Plumbers and electricians are expected to comply with new legislation
Thermostatic Controls
- Minimum controls are now required in installations (boiler, room, cylinder thermostats)
- Thermostatic control ensures the heat source doesn't cycle unnecessarily without demand
Insulation
- Insulation initiatives improve efficiency in dwellings
- Roof: Prevents loft heat loss
- Walls: Prevents wall heat loss
- Pipes: Prevents pipe heat loss
Energy Efficient Lights
- Customers are increasingly cost-conscious
- Compared to conventional bulbs, some energy-efficient bulbs use 30% less power, saving energy
- Examples of energy-efficient light bulbs are displayed
Double Glazing
- Double or triple glazing reduces energy and carbon emissions
- Nearly all new properties use double glazing, which has a lower U-value than single glazing
- Evacuated gap between glass panels acts as insulation
Draught Proofing
- Older properties often benefit from draught proofing to reduce heat loss
- Seals around doors and windows are necessary
Appliance Ratings
- Installing A-rated appliances (efficient appliances) is important
- Example of an A-rated appliance (Siemens condenser tumble dryer) provided
Renewable Energy Systems
- Installing renewable energy systems (solar thermal, photovoltaic, biomass, heat pumps, wind turbines) is becoming more common in new buildings
