Energy efficiency consulting companies, like Powerhaus Engineering, help enhance building design through thermal improvement, solar passive design principles and integrated systems, including solar and appliances.

At Powerhaus Engineering, we collaborate with a broad range of building and design professionals, as well as government entities, to enhance understanding and implementation of building energy efficiency.

This encompasses everything from the structure itself to the systems that power it, including renewable energy solutions.

Our offerings are diverse: from optimisation and compliance services for commercial buildings to renovation guidance and energy assessments for homes. We also provide compliance and optimisation advice for residential energy ratings.

Notably, we’ve developed Australia’s first home energy efficiency app, making it simpler for everyone to make informed energy decisions. Think of us as your friendly, practical partners in making energy work smarter for you.

An energy efficiency consultant is a specialised professional who provides expert advice and solutions to enhance the energy performance of buildings and systems.

At Powerhaus Engineering, our consultants possess a comprehensive understanding of building construction, the dynamics of heat and cold transfer within structures, and the functionality of heating and cooling systems.

Moreover, we consider the human aspect—how people live and interact within their spaces. Our team is a diverse mix of building designers, thermal performance engineers, and scientists, all united by a passion for creating comfortable, efficient, and environmentally friendly living environments. We’re committed to designing homes that not only feel good to live in but also contribute positively to the planet.

We work on all types of buildings.

  • Existing homes, including extensions and retrofitting
  • New homes
  • Apartment blocks
  • Townhouses
  • New suburbs
  • Community buildings, such as halls and churches
  • Commercial buildings, such as gyms and vet offices
