About Impact Zero
Impact Zero brings together engineering analysis, energy and resource efficiency, renewable energy integration and sustainability advisory services. Our work is focused on solutions that can be assessed technically, prioritised commercially and implemented in real facilities—not simply high-level targets.
Energy & electrification
Energy audits and performance assessments, heat pumps, process heat electrification, solar PV, battery storage and renewable energy integration.
Sustainability & decarbonisation
Emissions baselines, practical decarbonisation pathways, energy and carbon reduction opportunities, sustainability governance and implementation planning.
Water & circular economy
Water efficiency, resource recovery, waste reduction and circular economy opportunities informed by technical and operational requirements.
Engineering-led, implementation-focused
Our approach begins with understanding site conditions, available data, operating constraints and project objectives. We identify options, evaluate technical performance and investment implications, and develop practical recommendations that can guide implementation and verification.
- Understand the site: review energy and resource data, systems, assets and operating requirements.
- Evaluate opportunities: consider feasible technologies, controls, efficiency measures and integration requirements.
- Prioritise action: compare expected benefits, indicative costs, risks and operational impacts.
- Support delivery: provide technical input for implementation planning and performance assessment as agreed for each project.
Professional leadership and experience
Impact Zero is founded and led by Dr Paolo Corrada, an environmental engineer with doctoral qualifications from Politecnico di Milano and Queensland University of Technology. His professional credentials include Chartered Professional Engineer (CPEng), Registered Professional Engineer of Queensland (RPEQ) and International Professional Engineer (IntPE(Aus)).
His experience spans energy efficiency, building services, industrial and healthcare facilities, renewable energy and sustainability programs. Individual professional registrations belong to the named engineer and do not imply that every service or project is undertaken under a particular registration.
Project teams and specialist collaborators are selected according to scope and technical requirements.
Our project approach
We aim to make recommendations transparent and decision-ready, including key assumptions, data limitations, engineering constraints, indicative economics and expected performance where information is available. Outcomes depend on the specific site and are not guaranteed in advance.
