Refrigerated Walk-In Coldrooms (WICs) are applied in a wide range of facilities as part of the delivery stream from food source to consumer. However, WICs aren’t regulated for minimum energy efficiency performance, making them difficult to assess. WICs can be […]Read More
Energy Efficiency assessments can be a time consuming and complicated process. What sort of things can delay your result, and what can you do to get your report sooner?
1. Incomplete Building Information
To get us started on the Energy Efficiency […]
Energy efficiency assessments can be performed in several different ways – each with their own strengths & weaknesses. Firstly, there is the Deemed-To-Satisfy (DTS) Energy Efficiency Building Solution. To achieve compliance through a DTS assessment, every individual element of the […]Read More
Our Energy Efficiency Reports are written to provide an accurate & concise summary of how your building compares to the National Construction Code Performance Requirement and they include the Design Compliance Certificate (Form 15 in Queensland). They’re created with the […]Read More
When fibre roof insulation is compressed (to fit into a tight space, squished underneath purlins or even by a retaining mesh), its R-value decreases. This change isn’t a simple linear reduction, but a complex curve that’s different for each material.
What’s a Star Rating worth? How can you estimate the cost of electricity for heating & cooling your home from a House Star Rating? Is it even possible? It is, but it requires a little work. You’ll need to find […]Read More
JV3 Assessments are a complicated beast & not many Building Thermal Assessors know how to do them correctly. How do you check the validity of your Energy Efficiency Report to verify it’s correct? What conditions should apply to the assessment?
Your […]Read More
Following from Window Design for House Efficiency the contribution of windows to the total building Energy Efficiency is considered. The BERS 3.2 thermal simulation was used to determine the optimum eaves width for glazing of different heights. The optimum was […]Read More
The effective total Resistance to Heat Transfer for single-glazing is Rg = 0.16 m²K/W (disregarding the frame). A Brick Veneer wall (stud and plasterboard) with Aluminium foil insulation has a Resistance of Rw = 1.56 m²K/W, which is almost ten […]Read More
