Mechanical services specialist HVAC, BMS, and energy management consultancy delivering cost-effective, energy efficiency-led design and recommissioning for Australian enterprise.
We deliver cost‑effective, energy efficiency-led HVAC/BMS/DHW design and optimizations rarely provided at this depth in the market.
GreenKon Engineering is a mechanical services specialist HVAC, BMS and energy management consultancy, and NABERS Assessors, led by its founder and director Alex Koncar, an International APEC Professional Engineer and recognised industry expert.
With 30+ years of expertise across commercial, government, cultural, health and industrial sectors, we bridge the gap between traditional mechanical engineering and modern building automation.
We specialize in identifying “hidden” low-hanging fruit across operations and maintenance of mechanical services, ensuring short paybacks on our projects while educating clients and maximizing "value for money."
Deep mechanical expertise combined with cutting-edge analytical tools to identify, design, and implement massive energy reductions.
Tenders, innovative design, optimizations and recommissioning of mechanical services (HVAC, BMS, DHW, and pool systems) to reduce energy, water, and emissions, while extending equipment life and improving comfort.
Accredited NABERS Ratings for hotels, shopping centres, offices, and strata buildings. We provide actionable, cost-effective upgrade paths rather than just compliance reports.
Detailed Level 2 & 3 ASHRAE audits combined with deep BMS interrogation, looking beyond static calculations to true operational systems checks.
Comprehensive feasibility reports to ensure clients make fully informed capital expenditure decisions about potential energy projects.
Customized corporate and operational training programs, engineered for specific teams, clients, or equipment, utilizing our unique custom training tools.
Highly cost-effective energy contract negotiations. Our engineering knowledge allows us to secure better rates than traditional energy brokers.
Custom HVAC and BMS maintenance contract drafting that eliminates grey areas, ensuring contractors remain accountable and clients avoid blank cheques.
In-depth troubleshooting of design faults, operation/functionality issues, compliance, commissioning defects, and HVAC/BMS efficiency errors.
Successful end-to-end administration of local, state, and federal energy grants, ensuring full compliance and execution of approved activities.
Reducing absolute physical meter counts through smart layout design, utilizing virtual meters and virtual variables (VSDs, loggers, etc.).
Solar PV array sizing optimization, combined with specialized designs for domestic hot water (DHW) and swimming pool supplementary solar heating.
Clear, cost-effective compliance strategies outlining three simple options to meet strata building sustainability and legislative mandates.
Custom-engineered solutions and management methods designed to unlock deep energy waste where standard methodologies fail.
Delivering up to 30% more savings than conventional Economy Cycle BMS Control Strategies while significantly improving Indoor Air Quality (IAQ).
Reduces ventilation heating/cooling energy costs by up to 50% compared to standard conventional Demand Controlled Ventilation setups.
Unique controls sequences designed to maintain stable Indoor Air Quality and space temperatures during extreme hot days (35°C to 40°C).
Unique air handling unit (AHU) fan-energy reductions achieved through the innovative utilization of chilled water (CHW) coil heat exchange dynamics.
Minimizing chilled and condenser water pumping power via unique specification of MIN and MAX speeds and control logic for modulations.
Saves equipment costs by minimizing the number of physical meters while providing Facility Managers (FM) with clean, user-friendly reports.
Tailored DX and custom-designed AC units for buildings in tropical/subtropical areas, museums, and galleries requiring precise humidity profiles.
Dynamic, live control tuning algorithms that modulate VAV box dampers to reduce fan pressure requirements without sacrificing zones.
Configured specifically for hotels to provide efficient, centralized outside air supply to guest rooms dynamically.
Comprehensive sets of custom mechanical engineering tools optimized for hotel guest room operations and scheduling.
Unique, practical energy training sessions customized specifically for site Facility Managers and mechanical service contractors.
Rigorous reporting templates and metrics that hold maintenance contractors accountable for the performance of HVAC assets.
A simple, highly structured checklist for building managers to quickly scan and eliminate daily energy inefficiencies.
Step-by-step energy awareness induction programs ensuring new staff members adhere to organizational efficiency standards.
High-depth continuous tracking and data analysis templates that altogether remove the necessity for recurring expensive energy audits.
Trusted by leading hospitality groups, public institutions, and commercial enterprises across Australia and the Pacific.
