This presentation outlines 5 steps to making a home more energy efficient: 1) Check your energy plan for savings of $600/year, 2) Improve insulation and sealing for thermal comfort, 3) Upgrade appliances like heating, hot water, and windows for major cost savings, 4) Consider getting off gas and installing solar panels, and 5) Set goals and get support to follow through on efficiency upgrades. Making these changes can save homeowners considerable money and emissions over the long run while improving comfort and resale value.

Actsmart Sustainable Home Advice 5 steps to an energy efficient home Presenter: Ren Webb
My house Permaculture food production garden Low cost/DIY energy efficiency retrofit - 2 stars to 6.9 stars All-electric home very low usage: $200 per quarter Solar system generating 5 times more energy than we use
Suite of programs to help support households: Actsmart Sustainable Home Advice Home energy assessments Actsmart Eco Challenge webtool Also promote Heating and hot water upgrade rebates program
Feel free to ask questions The only silly question is the one that isnt asked
Why care? An energy efficient house can: save a considerable amount of money and emissions over the life of your home enjoy better thermal comfort & health outcomes enjoy greater energy security improve the re-sale value of your home Make you love where you live
Annual energy usage - average Canberra home Heating 60% Hot water 16% Electric appliances 15% Lights 4% Cooking 3% Cooling 2% Adapted from Residential energy use 2008, and Residential baseline study 2015
1. Are you on the best energy plan? Average middle-income Canberra home spends $3400 a year on energy (electricity and gas 2017/18) 25% discount on usage charges = $600+ per year saving well worth 20 mins on-hold! Review every 6-12 months they do not reward loyalty! www.energymadeeasy.gov.au Energy costs from: Australian Energy Regulator www.aer.gov.au
2. Er...do you know your EER (Energy Efficiency Rating)? Improve the thermal performance of your home: Check your contract of sale for the EER report. Implement recommendations 2 stars to 6+ stars for under $4000 possible with DIY
Have you draught proofed your home? Best bang-for-buck improvement Affordable, easy and makes a big difference Website, DIY videos, workshops
Does your insulation need upgrading? Ceiling R5 (25cm thick), walls R2.8, underfloor R2 Reduces heating and cooling costs and improves well-being
Are your windows well-dressed? Heavy drapes and pelmets and or thermal blinds Shade windows, walls, and hard surfaces around your home - summer
Are you running a tight-ship? Opening and closing curtains Closing internal doors, curtains in openings without doors Temperature settings Solar passive = active operators
3. Could you save with efficient electric appliances? Heating Biggest cost = biggest opportunity Split system ACs up to 600% efficiency!
50m2 living area, heating load 18738 MJ/per year. Calculated at 21.7c per kWh for electricity and 3.2c per MJ for gas. $1,133 $802 $709 $342 $241 $54 $35 $0 $200 $400 $600 $800 $1,000 $1,200 Electric element heaters Old gas flued wall heater 5 star gas flued wall heater 2.5 star reverse cycle split system 5.5 star reverse cycle split system Approximate annual cost to heat a 50m2 living area in Canberra Additional Cooling
Hot water Behaviour change Low-flow showerhead Upgrade to a heat-pump Got solar PV, use hot water to store energy
From 2020, gas will make-up 20% of the ACTs emissions $300ish per year supply charge and prices rising New-build all electric home - $5000 extra up-front for $1600 per year saving (with 5kW solar PV) compared to house with gas 4. Can you get off gas?
If you have a sunny roof install some! Systems are cheap but feed-in-tariffs are low Secret - self-consumption 5. Can you install Solar panels? System size (panels) 2 kW (8) 3 kW (12) 4 kW (16) 5 kW (20) 7 kW (28) 10 kW (40) Cost (total out-of- pocket) $3000 - $4,500 $3,500 - $5000 $4000 - $6000 $5000 - $8000 $6,500 - $10,000 $10,000 - $14000 Typical costs guide only
Graph from solarchoice.net.au
With 65% self-consumption (home during the day): typical payback 3-5 years (20-25% returns) With 20% self-consumption (shout-out to all the 9-5ers): typical payback 6-8 years (12-15% return) Load-shift usage, convert to all-electric home to maximise benefit Solar panels Figures from: www.solarquotes.com.au/solar101.html
Evidence suggests most people do not follow through! Information is not necessarily the key barrier Write down 3 changes that you would like to make and the main benefit you can see for each When would like to have made it by? Would it be ok if I gave you call you after the last date to see how you went and whether you need any support?

Editor's Notes

  • #9: This is about the theoretical amount of heating and cooling you need to put into your home. There is quite a bit to this step draught proofing, insulation, windows
  • #15: You could potentially save more energy/money by moving to a more efficient heater!
