Fire Testing & Building Certification
We are registered on the Fire Protection Australia (FPA) as a certified Fire Safety Assessor.Accreditation number: F053461A City Building Services provides validation and certification stating the installation, the equipment and performance of the installed and commissioned fire systems to ensure that they comply with respective codes and standards and are in-line with the approved design
One of the best ways to increase HVAC efficiency is to optimize heating and cooling source equipment for hot water and chilled water. There is a basic conflict between optimizing efficiency of distribution systems and optimizing efficiency of source equipment. For distribution, hotter hot water and colder chilled water can bring greater temperature differential across the system, reducing required flow and transport energy use. For sources of heating and cooling, however, it is more efficient to produce cooler hot water and warmer chilled water. Optimizing these conflicts will result in the most energy-efficient systems.
Fire Damper Inspection
Fire Dampers are a critical part of a buildings safety as they assist in the compartmentalization of fire areas in a building. They are often located in the HVAC duct work and their purpose is to block the spread of a fire, in effect closing off the duct at a firewall so they work as part of a larger fire system.
Annual building fire certification requires 20% of all fire dampers to be checked and recorded. The principle is that the next year another 20% of dampers will be checked so that after 5 years of inspection all dampers have been inspected.
As dampers are seldom seen, there can be a tendency to underestimate their importance and as such, some service companies will rush a visual inspection knowing it is unlikely anyone will ever inspect their inspection. Dampers can be subject to poor installation, corrosion, blockages and impediments, cumulative dust, microbial growth and mechanical failure. As such, the inspections every 5 years are more important than you at first might think. City Building Services takes its inspection obligations seriously and has developed a checklist that includes taking pictures so there is a higher quality of inspection and record. In summary, our checklist also looks at labels, wall penetrations and gaps and packing, operation of the flaps, check for obstructions, connections, the duct and state of fusible link,
