Tiivistelmä
The objective of this thesis was to produce a concept for a renovation of a house in Sydney, Australia to meet low energy requirements. New low energy houses have existed for many years, although the concept of renovations can create many challenges which will be looked at through this thesis.
Firstly, the concepts of passive house and low energy building were analysed to understand the requirements of these two concepts. Next, a real-life case study was reviewed to understand the possibilities for improvements, as well as what potential problems could arise.
An existing house in Sydney, Australia was utilized for the model and an evaluation of the existing building elements were reviewed to understand, where potential improvement could be achieved. Although there are many other methods that could help to achieve the low energy requirements, this thesis only considered feasible and practical solutions. Having calculated the existing U-values of the house, this allowed for the modification of the building elements to surpass the target values. The results show the final values of the building to indicate that it could reach the low energy status.
The methods in this thesis can be utilised to understand where different area of a house or building can be improved. Although every building is never the same the principles used throughout this thesis can be incorporated into any house or building, leading to improved indoor air quality and energy efficiency.
