NAT: How Proactive Mechanical Ventilation Maintenance Can Save Your Strata Property Time, Money and Stress

This article about proactive mechanical ventilation maintenance has been provided by Tracey Wyber, Trackie Industries.

We see it all the time – strata properties that are allowed to fall into such a state of degradation that major repairs are required to fix the problem, leading to overblown budgets, huge disruptions and unhappy owners.

But there’s another way – having a preventative and proactive maintenance approach.

However, before we go any further, let’s explore exactly what mechanical maintenance is…

Mechanical maintenance involves looking after all the mechanical services in a building including:

Controls
Electrical systems
Fans
Duct work
Carpark exhaust
Toilet exhaust
Fresh air
Associated systems

What is involved in quarterly mechanical ventilation maintenance?

Cleaning the system to ensure everything works efficiently
Checking all electrical terminations are tight and there are no burnt cables
Checking that all controls work as they are supposed to
Inspecting, maintaining and carrying out greasing, fan belt changes
Cleaning VSD fans cooling fans
Test and calibrate atmospheric contamination systems

What are some of the consequences of not carrying out quarterly maintenance?

Systems stop working altogether through mechanical or electrical failure
Systems block up and air flow is compromised
Mould build up appears
In carpark exhausts, ducts become rusted out so dangerous gases cannot be removed from the carpark
Large expense when equipment needs to be replaced
Health of residents is compromised
Extra energy expenses due inefficient and poorly maintained equipment

Food for thought…

We service our car on a regular basis to prevent a costly breakdown, why not do the same with our apartment blocks.

Case study

What happens when regular mechanical maintenance is not carried out.

This case study involves a lovely Eastern suburbs apartment block in Potts Point, Sydney. The residents of the building were becoming increasingly unhappy because they were noticing mould levels in their bathrooms on the rise and we all know mould and health do not go together.

Trackie were sent in to investigate the problem and started by checking air flow readings in each apartment. Not surprisingly, the air flow figures were low. Not enough air was being circulated through the ventilation systems of the building. AS1668.2 states, there must be minimum air flows in each bathroom to satisfy the standard.

The next step was to look at the rooftop fans to see what they were doing and once again, not surprising, they were not operating effectively, with one not operating at all. So, the fans were replaced, vents cleaned and the air flow reading were better, but still not up to scratch. Upon further investigation, it was found that many fire dampers had been placed incorrectly and were blocking air flow. Once rectified, the building began breathing beautifully again.

Moral to the story

This long and expensive (60K) process could’ve been avoided had the building had regular mechanical maintenance.
