Air Filtration & Quality Monitoring

We continue to work with our contractors and building managers (who refer to their own advisors) to monitor air quality and filtration in both owned and leased buildings:

  • Cooling towers are inspected on a weekly and monthly basis with monthly water testing reports provided by contractors.
  • All cooling towers are fitted with an automatic chemical dosing system to maintain the required water control properties in real time.
  • All cooling towers are cleaned quarterly in line with government regulations.
  • All cooling towers are registered with the Victorian government and we are required to submit an annual certification for compliance.

An air filtration systems upgrade was completed in 2022 across both owned and leased buildings, see below for more information.

Air Filtration System Upgrade

What has been upgraded?

We upgraded the existing return air filter banks from the current 40-45% average efficiency to 90-95% average efficiency.

Do the air filtration filters meet minimum requirements?

All air filtration filters meet or exceed the WBS (Well Building Standards) minimum requirement for filtration of outside air (F7/MERV 13) and the (NAFA) National Air Filtration Association efficiency class filters in commercial buildings.

What about BCL leased properties?

We are working with the building managers for leased properties (under advice from their advisors) to ensure air filtration systems meet or exceed the WBS (Well Building Standards) minimum requirement for filtration.

What is the benefit to occupants?

These more efficient filters provide better protection against virus survival conditions which are temperature and humidity dependent in chambers on our floors in our buildings.

Air quality monitoring system in BCL owned buildings

What is an air quality monitoring system?

The EP5000 is a ModBus (connected to the Building Management System) indoor air quality probe. Click here for more information.

Where will it be installed?

These are installed in the ceiling at the entrance of each floor.

What is the benefit to occupants?

The indoor air quality probe allows ongoing monitoring of air quality and we will use this information to rectify the air flow in real time.

  • Air conditioning system does not have filters, however the BMS (Building Management System) enables changes to the air mix intake together with the ability to open windows.
  • The amount of outside air introduced can be adjusted in real time to provide greater volumes than the minimum standard.
  • Installation of indoor air quality probe on each floor. Click here to read more.
  • Grade F8 filters installed with average efficiency from 40-45% to 90-95%. Click here to read more.

  • Indoor air quality probe installed on each floor. Click here to read more.
  • Grade F7 (national minimum standard) filters installed as advised by Charter Hall (building manager).
  • Grade F9 filters installed as advised by Colliers (building manager).
  • Grade F9 filters installed as advised by JLL (building manager).
  • CO2 sensors are fitted on each floor to ensure maximum outside air is supplied.
  • Grade F7 (national minimum standard) filters installed as advised by Knight Frank (building manager).
  • The amount of outside air introduced can be adjusted in real time to provide greater volumes than the minimum standard.

LED Lighting

What has been upgraded?
  • All existing lighting has been upgraded to LEDs in Owen Dixon Chambers East and Owen Dixon Chambers West.
  • All common area and bathroom lighting has been upgraded in Aickin Chambers.
What are the benefits?
  • LED lighting is highly energy efficient, with the lighting selected for each building being VEECs accredited (Victorian energy efficiency certificates) and designed to cast the perfect amount of light (4000k warm white) for office environments.
  • Visually more appealing with a soft warm light that has scientifically improved health benefits.
  • Environmental benefits including less power consumption per unit (lumen) of light emitted and lower carbon omissions due to a longer life span.
  • Longer lasting (up to 7 years) without the need to replace and removing the need for ongoing maintenance for existing aged, flickering dull or damaged lights.
