Energy Efficiency Methods And Techniques V.2
- 2. Energy Efficiency Methods and Techniques Choosing to manage the way you use energy means you can have lower bills, a warmer, healthier home and less of an impact on the environment Essentially improvements in energy efficiency enable achievement of the same result with less energy or achieving an improved performance with the same energy What does all this mean to you? More comfort and more savings More performance less energy
- 3. Energy Legislation EU Energy and Climate Change Package agreed at the European Council in December 2008, (i.e. 20% efficiency improvement, 20% renewable energy penetration and 20% greenhouse-gas emissions reduction by 2020). EU Energy Services Directive (ESD) Member States to achieve a 1% per annum energy efficiency improvement, resulting in a cumulative target of a 9% improvement in energy efficiency by 2016.
- 4. Energy Efficiency Energy Performance of Buildings Directive (EPBD) Energy performance standards Part L Limitation of Heat Loss through the Building Fabric Building Energy Rating (BER) certificate, which is effectively an energy label, is now required at the point of sale or rental of a building, or on completion of a new building. http://www.environ.ie/en/TGD/
- 5. Building Energy Rating (BER) kWh/m2/year kgCO2/m2/year CDER (TGD L) carbon dioxide emission rate Why? Protect buyers and renters of property You should know the cost of heating a property before building buying or renting it Improve the standard of house building in Ireland
- 6. Energy Efficiency Methods and Techniques The average household in Ireland uses approximately 25,000 kWh of fuel and electricity each year The cost per household is between €1500 to €2000 per year on average 70% improvement ??
- 7. Energy Efficiency Methods and Techniques Many common air leaks are overlooked How many of the avoidable ones apply to your house....?
- 8. Energy survey What Can Be Detected: Missing or improperly installed insulation Energy losses caused by air infiltration and exfiltration Building Defects Benefits: Reduce your heating energy costs Improve the comfort of your home Improved Indoor Air Quality
- 9. Non destructive test equipment An air tightness test using a blower door will measure the air leakage of your home and provide advice on how to eradicate air infiltration and draughts leaving you warm and snug in your home enjoying lower heating bills
- 10. Thermal Survey
- 11. Insulate, Insulate, Insulate… Heat will always flow from a warm area to a cold one. In winter, the colder it is outside, the faster heat from your home will escape into the surrounding air. It is therefore vital that as much as possible is done to prevent this. Insulation makes it much more difficult for heat to pass through your house exterior. Roof and wall insulation will greatly reduce what is known as the U value. The lower the U value, the slower heat is lost - and the less energy you need to keep your home warm. Insulation is your primary defence against heat loss and heat gain through the house envelope
- 12. Insulate, Insulate, Insulate… To get the biggest savings, the easiest place to add insulation is usually in the attic. U Value .16
- 13. Secondary Heating Independent research shows stoves are three times more efficient than open fires. While anything up to 70 per cent of heat from an open fire goes straight up the chimney, stoves retain as much as 70 per cent heat in the home.
- 14. Heating controls Can you heat your domestic water independent of space heating? Can you turn on your heating without heating your domestic water? Can you easily adjust the heat output from radiators ? Have you time control on your heating system that you can set for a week? Have you a separate temperature control for you hot water cylinder? Have you a separate time control on your hot water cylinder?
- 15. Heating controls
- 16. Energy efficient equipment The systems you use in your home have a big impact on your energy use and your environmental footprint

- 18. Air Tightness Good airtightness allows you to control your home's ventilation. Ventilation is an important part of a healthy indoor environment, as it helps maintain air quality and remove moisture
- 19. Efficient Lighting INCANDESCENT MINIMUM LIGHT CFL LAMPS Saving over 70 LIGHT BULBS OUTPUT Hours Watts Lumens Watts 1 K/Watt = 1 Unit of Electricity 40 450 9 - 13 1 . 890 Kw 60 800 13 - 15 3 . 150 Kw 75 1,100 18 - 25 3 . 500 Kw 100 1,600 23 - 30 4 . 900 Kw 150 2,600 30 - 52 6 . 860 Kw One unit of electricity is exactly equal to 1000 Watts of power used for 1 hour Install solar tube-type lighting in walk-in-wardrobes and toilets, where natural light can easily and effectively simulate artificial lighting.

- 21. Simple Improvements – At Home Turn your heating down to a comfortable 20ºC - lowering your thermostat by 1ºC will knock 10% off your heating bill. Wait for the dishwasher to be full before you switch it on Switch off lights when you leave a room Avoid unnecessary electricity use between 5pm and 7pm - help reduce national CO2 emissions. Don't overfill your kettle Use cold water for washing your clothes Fix dripping hot taps
- 22. Some words of caution!!! Don’t store water at temperatures less than 60°C ***– danger of Legionella disease *** Mixing valves will enable distribution at lower temperatures at 50°C to prevent scalding For older people just 1°C fall in room temperature can lead to a rise in blood pressure, a lower core body temperature and colder extremities Being cold in the home increases the risk of strokes and heart attacks and exacerbates COPD Chronic Obstructive Pulmonary Disorder. Don’t close room vents ***– danger of Carbon Monoxide poisoning *** FIT a Carbon monoxide monitor

Ingredients for a warm, healthy home Attic and wall insulation Efficient Space Heating Heating system + Controls Draught minimization Windows (if they are old or need repairs) Alternative energy such as solar heating Good Habits Energy efficiency is not about going without It is about getting more for your money and stopping the waste
