What is an Energy Audit?
Energy Audits are the key to a systematic approach for decision making in the energy management arena.
The simple rule applied in energy management is that "you can't manage what you don't measure".
energy consumption, within a home or business, to determine ways in which energy can be conserved.
Energy Audits attempt to balance the total energy inputs and costs with it's use, including identifying all streams, within the home or business, to determine ways in which energy can be conserved. It quantifies energy usage according to its discrete functions and down to each asset.
Energy Audit Standards
According to the Energy Efficiency Council of Australia "accurate and consistent energy auditing is critical to the uptake and quality of energy efficiency projects as it is often used as the basis for business case justification, project design and as a baseline to measure savings post-upgrade.
In 2014, Standards Australia released the new standard for energy auditing: AS/NZS 3598:2014, which sets out minimum requirements for commissioning and conducting three prescribed types of audits that identify opportunities for cost effective investments to improve energy performance.
Unlike the previous standard, the new standard is actually a series of standards focused on particular economic sectors:
The new series of standards are more rigorous, are outcomes-based and are focused on providing audit customers actionable energy conservation measures."
You can read more on the Standards and how to understand your energy bill at the Australian Government's Department of Industry, Science, Energy & Resources Energy website.
Demand Profile Analysis
Auditors review and capture all energy consumption assets by undertaking an asset audit of energy consuming devices on site.
We review the electricity and gas billing data for the site and review the interval data (30 minute interval data on right) to see consumption patterns.
Energy models of the assets are then harmonised against actual historical levels to ensure an accurate baseline dataset for which recommendations can then be formed, modelled and priorities based upon client requirements including CAPEX, OPEX, payback periods and carbon emissions.
Renewable Energy Options Analysis
To reduce electricity costs and manage onsite electricity grid demand, in addition to building management system (BMS) control of lighting, heating, ventilation and airconditioning (HVAC) and energy efficiency measures, renewable energy options are analysed specifically for the costs and constraints of the site.
Recommendations, Analysis & Asset Management
Element47 provides comprehensive analysis compliant with relevant Australian Standards in colour coded easy to digest formats.
We find clients prefer the use of colour coding of recommendations to highlight competing interests.
Clients also love that we use the digital cloud platform which enables us to deliver Data Capture which complements Element47's site assessment capabilities to provide efficient, comprehensive and low cost data capture services of energy assets.
Outputs enable Element47 to classify these assets into rooms and easily integrate captured and analysed assets into corporate asset management platforms for local governments, corporates and miners.
