Engineering solutions for energy systems in commercial buildings
Commercial buildings — including office complexes, retail centres and mixed-use developments — operate energy systems driven primarily by HVAC, lighting, elevators and increasingly electric vehicle charging infrastructure.
These facilities often experience strong daytime electricity demand and peak loads driven by climate control and occupancy patterns.
K24Energy designs PV, BESS and EMS architectures that optimise building energy systems, reduce operational energy costs and support electrification without requiring expensive grid upgrades.

Our Engineering Approach
Energy systems in commercial buildings are highly influenced by occupancy patterns and HVAC operation.
K24Energy applies an engineering methodology that integrates building energy behaviour with modern energy infrastructure.
Typical workflow includes:
How we work
| 1 | Load profile analysis | analysis of 15-minute consumption patterns |
| 2 | HVAC and occupancy load mapping | identification of cooling, heating and peak demand drivers |
| 3 | PV and BESS modelling | sizing systems based on building energy demand |
| 4 | Energy management architecture | EMS coordination of HVAC systems, EV charging and storage |
| 5 | Financial modelling | IRR, NPV and DSCR evaluation of energy investments |
| 6 | FEED engineering documentation | EPC-ready technical specifications and system design |
Energy Architecture
Commercial building energy systems typically combine several coordinated components.
Typical architecture includes:
✓ photovoltaic generation (PV)
✓ battery energy storage systems (BESS)
✓ energy management systems (EMS)
✓ integration with HVAC systems
✓ EV charging infrastructure coordination
✓ grid interaction and demand optimisation
These systems enable building operators to optimise electricity consumption while maintaining occupant comfort.
