Home Energy Assessments / Audits
Do you want to use energy more efficiently in the home, lower your household energy bills, make your home more comfrtable and reduce greenhouse gas emissions? Would you like to do all of this, without compromising your comfort levels at home?
A Home Energy Assessment can make this happen and Your Energy Friend is here to help and guide you through the process.
From the moment you make a booking on our website, we are busy trying to find you the best solutions for your energy efficiency needs.
Making a Booking
- Simply fill in the on-line form or call our main number, to organise your Home Energy Assessment.
- When we receive your booking, we will call you to organise a visit and discuss your expectations.
Analysis of Energy Usage
Before we visit your home, we send you an official NMI form to sign (National Meter Identifier). This authorises us to access 2 years of electricity usage data from your network provider.
To prepare for our visit, we analyse the NMI data for your household, drawing on over 15 years of industry experience and knowledge. We look at your daily usage trends and peak energy demands. We also check the differences between your general supply and controlled loads and identify standby power usage.
Analysing what time of day power is used, from which source and for what reasons, gives us a lot of information about your household’s energy needs. We can then save you money by mapping your energy needs at specific times of the day and year, to the most cost-effective power source available (eg Grid, Solar PV, Batteries).
On the day of your Household Energy Assessment, we explain everything we have discovered about your energy usage, linking it back to your bills, showing you how to make sense of and understand your electricity, gas and water bills.
Assessment of Building
Armed now with a good understanding of your energy usage, we arrive at your house, full of energy and enthusiasm to help you become more energy efficient, save money, and to increase the comfort of your home.
Our first task is to identify the impact of the sun, shading, insulation, ventilation and building envelope leakage on your household’s energy efficiency.
We inspect your house, focusing on the following areas.
- Insulation – we check the quality of insulation coverage in the roof and also do a sub-floor inspection where appropriate. Even just a 10% gap in insulation, can make it almost worthless.
- Building Envelope – thermal camera imagery helps us to identify any leaks in the building envelope, which can account for winter heat loss and reduced cooling capacity in summer.
- Passive Design & Shading – we look at existing layout of house, looking for opportunities to introduce passive design solutions such as effective shading and airflow solutions.
- Windows – we look at window positioning in relation to passive solar heat, passive cooling and ventilation, we also assess glazing and window coverage, eg blinds and curtains.
Assessment of Systems & Appliances
Finally, we turn our attention to your systems and appliances, assessing their efficiency, age, usage and functionality. We are looking for smart use of energy and if there are better, cost effective alternatives in the following areas.
- hot water system,
- heating and cooling systems,
- kitchen and laundry appliances,
- pool equipment,
- any other major appliances,
- building envelope / air tightness
- ceiling space and sub-floor inspection
- insulation inspection and recommendation
- standby power analysis
- gas and electricity comparison
- NMI data analysis
Energy Efficiency Opportunities
At the end of our visit, we sit down with you and your family and bring it all together. Everything that we identify and discuss with you, is captured in your Household Energy Assessment report.
The report lists actions for your household to consider. We also provide relevant website links, for further guidance that might be needed.
- First we explain our analysis of your NMI data and your energy and water bills, in relation to what we have learnt about your house, systems and appliances during the home visit.
- We show you the most cost-effective, energy efficient sources of power based on your daily usage trends, peak periods and standby power usage. For example, we explain how your daily usage patterns vary depending on the day or season and how usage patterns could be matched with solar generation and battery opportunities.
- We review the tariffs of your existing energy provider and help you locate the best electricity and gas retail options based on your household’s consumption, helping you to compare tariffs from different energy providers.
- We show you how to gain maximum value from your existing systems, for example the hot water system, heating and cooling systems, and where upgrades are needed to make your home more efficient. We also review which source of power is more energy efficient for each system.
- Hot water systems are a major component of energy bills and we discuss in detail, the different options for hot water and also identify any opportunities for water savings.
- We explain how much each appliance costs you to run, what is the best source of power for each one and how to reduce standby power in systems and appliances.
- We make suggestions for modifications to the house and pool, based on passive design and shading opportunities and discuss what tariffs the pool pumps, pool heating is running on and where there are opportunities for savings.
- We suggest water saving opportunities, in relation to the hot water system, pool and rain-water tanks, so that home water usage can become more efficient and water costs reduced.
Finally, we review your energy efficiency goals in relation to cost savings, carbon footprint and increasing your comfort levels, to see where we can support you to implement some of the energy efficiency strategies we have identified and check that we have met all of your expectations.
