Impact Zero | Engineering, Energy & Sustainability
Independent engineering advice to improve the performance, reliability and efficiency of buildings, HVAC systems and industrial plant — from technical assessment and feasibility through to implementation and verification.
Discuss your projectWho we support: Commercial and institutional buildings, healthcare facilities, manufacturing and industrial operations, education campuses and public infrastructure. We work with asset owners, facility managers, project teams and operators across Australia and internationally.
Impact Zero takes a whole-system engineering approach: understanding how equipment, controls, operating schedules and site requirements interact before recommending changes. The objective is practical, technically defensible improvement — not simply replacing equipment.
Review air-handling units, ventilation, heating and cooling systems, hydronic distribution, pumps and fans. Assess operating conditions, control strategies, comfort, indoor-air requirements and opportunities to reduce unnecessary energy use.
Examine chilled-water and heating-water systems, chillers, boilers, heat exchangers, cooling towers, buffer storage and associated pumping. Evaluate plant sequencing, setpoints, part-load operation and potential equipment upgrades.
Assess building management systems (BMS), sensors, metering, time schedules, setpoint resets and control sequences. Develop practical recommendations for monitoring, fault detection and improved operational control.
Investigate compressed air, process heating and cooling, motors, pumps and related utilities, including the interaction between process demand and building services. Identify technically feasible improvements without compromising production or operational requirements.
Compare refurbishment, optimisation, replacement and electrification options. Consider load profiles, technical constraints, integration requirements, capital and operating costs, maintainability and implementation risks.
Support scope development, technical specifications, procurement review, commissioning planning, measurement and verification, and post-implementation performance assessment. Help translate engineering findings into actions that can be delivered and checked.
Depending on the project, work may include engineering inspections, targeted data logging, energy assessments, feasibility studies, design reviews and independent technical advice. Recommendations are tailored to the site and the quality of available information.
Should an existing chiller or boiler be optimised or replaced? Are variable-speed drives appropriate for a pumping system? Can a building management system reduce out-of-hours operation? What are the technical and commercial implications of a heat-pump retrofit? Which interventions can be implemented first without disrupting critical operations?
We examine these questions in the context of safety, reliability, required service levels, operating costs, carbon impacts and lifecycle value. Project-specific savings and payback estimates require verified site information and agreed assumptions.
Engineering optimisation often intersects with energy efficiency and assessment, renewable energy and electrification, and decarbonisation planning. Impact Zero can consider these workstreams together so that individual equipment decisions support the wider facility strategy.

The answer depends on measured performance, equipment condition, load profiles, controls, reliability requirements and full lifecycle cost. Replacement is not automatically the lowest-risk option.
