Beyond expensive building and equipment upgrades and retrofits, re-commissioning (analogous to performing a comprehensive tune-up on your car) and automated fault detection and diagnostics (FDD) for building systems offer significant energy efficiency opportunities in commercial buildings.
With Heating, Ventilation & Air Conditioning (HVAC) systems attributed to 40-50% of commercial building energy consumption (46 Mt CO2-eq. p.a.) in Australia (Pitt & Sherry, 2012), FDD tools and services are driving energy savings and emissions reductions, in addition to improved maintenance practices and outcomes from commercial building HVAC systems and more recently other building energy systems.
With numerous commercial offerings and delivery models for FDD solutions available in the Australian market, it is often difficult for potential customers and end users to determine which solutions offer the most value considering factors such as implementation cost, ease of use, energy savings, improved maintenance practises and outcomes, and ultimately improved comfort and productivity of the building occupants.
The scope of this project was to undertake a rigorous and systematic independent evaluation of the potential benefits of automated FDD solutions delivered as a managed service in Australia. The intent of the evaluation is to encourage greater uptake of FDD tools and services in Australia by assisting building owners, operators and HVAC&R maintenance contractors to evaluate and select their preferred FDD solution for future roll-out across their respective building or portfolio, therefore significantly increasing the energy efficiency of commercial building stock in Australia.
The main objective of this Final Report (Part I), is to highlight key benefits and outcomes made possible through the implementation and ongoing use of automated FDD solutions in Australian commercial building stock. A subsequent confidential report (Part II) will provide an objective performance evaluation of some of the leading FDD solutions in Australia.
Research on the energy efficiency of the different components of buildings – their shell, built-in appliances, plug-in appliances, floor size and floor plan, as well as position on site – all have contributions to make to amount of energy consumed. When combined with renewable...Read more
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
Pilots are powerful for two reasons: 1. They are a great way to bring together groups of people to demonstrate how effective collective action can be in helping to change the status quo. More voices, more influence. Pilots, backed by evidence and research, can highlight and expose the challenges and blockages, particularly in government, far more effectively than any individual can (despite many individuals trying!). They also provide perfect opportunities for identifying solutions. And, 2. pilots provide the numbers and the evidence that decision-makers need, in order to believe and make change.Read more
The Performance Requirements of the National Construction Code (NCC) can be met using either a Performance Solution or a Deemed-to-Satisfy (DtS) Solution or a combination of both solutions. The following demonstrates the performance based design process that should be used in conjunction with the Development of Performance Solutions Guidance document.
Radiant cooling and heating has the potential for improved energy efficiency, demand response, comfort, indoor environmental quality, and architectural design. Many radiant buildings have demonstrated outstanding performance in these regards, and application of the technology in commercial buildings is expanding.
AIRAH undertook this project on behalf of the whole of industry to provide a forum or mechanism whereby the transition to low -‐ emission HVAC&R practices and technologies could be discussed openly and transparently. The topic is broad and the views are varied and often conflicting. The content of this paper is based on submissions rece \ived from industry stakeholders. Hence , many statements and conclusions are not referenced to published documents. This is neither a research paper nor a definitive situational analysis; this paper simply documents an industry discussion.
This Guide to Implementing Low Carbon Retrofits for Social Housing is intended as a simple to use reference for social housing asset managers and others involved in social housing upgrades. The guide presents a concise summary of effective energy efficiency optionsfor social housing properties, including:
