Why reliable HVAC Maintenance Matters
Compliance Risks: Poorly maintained HVAC systems can cause BWOF failures and costly re-inspections.
Comfort Complaints: Temperature issues quickly lead to tenant frustration and loss of trust.
Financial Impact: Reactive repairs cost up to 4x more than planned maintenance.
Energy Efficiency: Dirty coils and faulty controls drive up power bills unnecessarily.
System Lifespan: Neglected units fail years earlier than expected, increasing capital costs.
Partnering with CBS means fewer breakdowns, fewer complaints, and complete control over your building’s comfort and compliance.

CasenStudy: Dulux Wellington
Challenge:
Dulux required a highly controlled laboratory environment to ensure precision testing of paint formulations. The facility needed to maintain temperature stability within ±0.5°C and humidity within ±2%, while safely managing chemical vapors. Compliance with stringent industrial laboratory standards and building consent regulations was essential. The project also faced a tight timeline, with installation needing to occur without interrupting nearby operations. Finally, the systems had to allow for future expansion and evolving testing requirements.
Solution:
CBS delivered a fully integrated mechanical, electrical, and plumbing (MEP) solution designed for precision environmental control and long-term efficiency. The team coordinated all building services under one contract, ensuring seamless system integration and simplified project management. HVAC and control systems were engineered for chemical compatibility, energy efficiency, and adaptability to future needs, all while maintaining full operational continuity and meeting Dulux’s strict compliance and performance requirements.
Result:
The project achieved exceptional performance outcomes, including ±0.3°C temperature stability—exceeding specifications, and a 100% first-time BWOF pass with no compliance delays.
Completed two weeks ahead of schedule, the laboratory operates with zero downtime and 15% greater energy efficiency than the original design. Stable environmental conditions have enabled 30% faster testing cycles, improving product quality and accelerating Dulux’s time-to-market for new paint formulations.
