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 […]
The first step to answering this question is to ask another question: what exactly is included in your building envelope? But the answer is more complicated than you might first think. Correctly or incorrectly defining the building envelope can significantly […]Read More
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
In hotter climates, ceiling fans can provide a big increase in a building’s energy efficiency rating. But how does the National Construction Code (NCC) & National House Energy Rating Scheme (NatHERS) Software calculate their exact benefit? Time to get technical!
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
Testing of Proposed BCA2010 Volume 2 House Energy Efficiency Deemed-to-Satisfy Measures with BERS Pro Energy Ratings
We were commissioned by the Australian Building Codes Board to investigate the new Deemed-To-Satisfy requirements in BCA2010. In essence, we were contracted to set the goal posts to make sure the requirements for Deemed-To-Satisfy assessments were roughly equal to the […]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
