How can you reduce the cost of insulating a Building Envelope?
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 MoreJV3 vs DTS: Construction Cost Savings!
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 MoreHow Ceiling Fans Work, Thermally Speaking
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! […]

How to control heat transfer
There’s many guides out there on designing energy-efficient buildings, both houses and commercial. But what do you know about heat transfer & what can you do when your building is too hot? We’ve come up with a few tips to […]
Read MoreOptimal Window Eaves Shading
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 MoreWindow Design for Building Energy Efficiency
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 […]
