Nestled amongst Currumbin Valley’s serene bushland, the Gold Coast’s harsh, humid summers and mild winters guided our comprehensive NatHERS thermal performance assessment and energy efficiency compliance solutions.
Designer: Private / Owner
Location: Currumbin Valley QLD
NCC Climate Zone: 2
NatHERS Star Rating: 7. 1 Stars
A beautifully designed home nestled amongst nature.
This exquisite family sanctuary is surrounded by Blackbutt and Hoop Pine Forests, Currumbin Valley, instilling both privacy and tranquility as well as providing ample shading from Queensland’s harsh summer sun.
Our client was ‘budget conscious’ therefore, much time was spent relaying sustainable and energy efficient solutions to achieve the desired outcome.
Australia has 8 main climate zones, as defined by the National Construction Code (NCC 2019). Each of these climate zones has different design and construction requirements.
The Gold Coast falls into the NCC Climate Zone 2, whereby the summers are warm, muggy, and wet; whilst the winters are short and mild.
In hotter, more humid climate zones, it is commonly understood that the summer season impacts the cooling load more so than the winter season impacts the heating load.
These are important factors that must be considered by all parties during the design process.
The Heating Load is the amount of heat energy that is to be added to a living space to maintain the temperature in an acceptable range.
The Cooling Load is the amount of heat energy that is to be removed from a living space (cooling) to maintain the temperature in an acceptable range.
NatHERS Assessment Results
Thermal performance is the amount of heating or cooling that makes the interiors of a home comfortable. In other words, it is a measurement of how efficiently your home can retain heat.
A building with good thermal performance will need less energy to keep the insides warm and comfortable. (CSIRO)
Thermal Performance Solutions
Our client opted for polished concrete floors, ceiling fans and a combination of single glazed louvred and sliding windows to enhance cross ventilation and cooling breezes.
With great consideration to the design and the decision to incorporate hardwood batten shade screens as well as raw fibre cement cladding, the following thermal performance solutions were selected as a result of the NatHERS Assessment:
