Approach
At askerrobertson, we see sustainable design and construction as an opportunity to create homes that are not only comfortable and beautiful but also connected to nature and mindful of environmental impact. By combining biophilic design with advanced construction technology and healthy materials, we prioritise health and wellbeing. Our ambitious NatHERS* targets, along with Passivhaus* and LBC* options, allow us to reduce resource use and create spaces that respect both the natural and built environment.
Design
Whether for new builds or alterations, our design approach is tailored to the site, optimising cost-effective, passive design principles. By strategically incorporating solar orientation, shading, and cross-ventilation, we achieve natural lighting, heating, and cooling, while carefully planned airflow regulates indoor temperatures. To achieve optimal energy efficiency while staying within budget and preferred standards, we can engage an energy rating consultant at the concept stage. This allows us to refine and enhance the design early in the process.
Water
In Australia’s dry climate, water is a precious resource, so we prioritise the most efficient products to minimise consumption. Our designs reduce reliance on mains water by incorporating site-specific rainwater tanks and, where possible, wastewater reuse systems. We also design water-efficient gardens with native and site-appropriate plants to improve soil moisture retention and health, supported by efficient, water-saving irrigation systems.
Energy
We reduce the need for heating and cooling by applying passive design principles that respond to the local climate, keeping indoor temperatures comfortable year-round with minimal reliance on mechanical energy. By using ecologically sustainable materials and high-quality construction, we lower energy consumption and maximise the potential for renewable energy solutions.
Air
To optimise indoor air quality, we design for cross-ventilation, promoting natural air circulation throughout the home. For added efficiency, we can incorporate automated mechanical systems to maintain a healthy, safe, and comfortable environment. From design through construction, we minimise pollution sources and prioritise natural, non-toxic, and environmentally responsible materials.
Materials
The selection of materials when building or renovating plays a critical role in a home’s performance, energy efficiency, and durability. We implement a waste minimisation strategy that prioritises reduction, reuse, and recycling throughout the design and construction phases. By opting for sustainable, high-performance materials and energy-efficient double-glazed windows, we strive to reduce the project’s carbon footprint and environmental impact. This approach not only enhances indoor stability and comfort but also lowers energy consumption and utility costs.
Standards*
NatHERS*
The Nationwide House Energy Rating Scheme provide star ratings for energy efficiency using computer modelling based on architectural drawings and sustainability assessments, and is the most common way to ensure minimum energy performance requirements of the NCC are met.
Passivhaus*
Passive House is a high performance construction standard originally developed in Germany, that achieves year round thermal comfort with minimal heating and cooling and is characterised by five key design principles and performance criteria.
- Airtightness
- Continuous thermal insulation
- High performance windows
- Minimised thermal bridges
- Mechanical ventilation and heat recovery
LBC*
The Living Building Challenge is a philosophy, advocacy tool, and certification program defining todays most advanced measure of sustainability in the built environment and provides a framework for designing, constructing, and improving symbiotic relationships between people and all aspects of the built and natural environments.
