22 Giffnock Avenue

FM Firm: Cushman & Wakefield

FM Client: NSW Department of Transport

Facility Manager Firm: Brendan Tuedt

22 Giffnock Avenue is a seven storey facility within the Macquarie Park building complex. There are several tenants within the building, with the predominant stakeholder being the NSW's Department of Transport.

Working across these different stakeholders presents a challenge to the Cushman and Wakefield team in diagnosing issues, esepcially when they affectmultiple tenants in different ways

The problem

The client was looking for a way to understand the comfort issues that were arising in the facility. These issues had escalated to the point that they were looking at substantial infrastructural investment

Importantly, because of the conflicting spectrum of complaints that were being experienced it was unclear the direction to pursue. The FM felt that a more comprehensive picture of the building was required.

red is hot, yellow is comfortable and blue is cold

Action plan

Hux identified the key comfort issues for the FM team, making the development of an action plan simple.

Cost / Benefit

Hux was able to save Cushman & Wakefield thousands of dollars, both through supplying data much cheaper than the alternatives, but also allowing the FM company to avoid incurring additional time and resource costs such as liasing with the BCMS solution provider in accessing system data.

How did Hux achieve this?

Hux reviewed the plans and proposed a monitoring solution of 22 sensors, detecting tempereture, humidity , and carbon dioxide levels.

Diagnosis through data

Hux was able to easily identify one of the key issues with the building - a dividing wall splitting the HVAC system, leading to serious performance issues on both sides of the wall.

Hux was undertook a complete installation at the site with minimal impact on occupants during their busy Friday.

Because the Hux sensor network required no interfacing with the IT systems in the building, the only person involved was the FM.

This made their job a lot easier and made Hux the clear choice for their data needs.

Over Conditioned?

Through looking at the rate of change, Hux was able to show Cushman & Wakefield staff that their HVAC system was not over conditioning.

Hux Insights used in this deployment


Conditioning inefficiencies

Overheating / overcooling, economy cycle and dead band opportunities.

Through directly monitoring factors such as overheating (where active heating pushes temperatures above desired thresholds), overcooling, and excessive spatial temperature variation can be quantified, and opportunities such as economy cycle and natural ventilation are assessed

Ventilation Assessments

On demand C0₂ assessments identifying under-ventilation issues.

Carbon dioxide (CO₂) assessments are a terrific way to understand ventilation problems and are often the answer to intractable discomfort CO₂ has significant impacts on staff productivity but issues can be very easy to solve once they are understood. Hux´s detailed CO₂ mapping makes understanding simple and intuitive.

The outcome

Hux was able to produce detailed information about the site with minimal effort.

Because Hux takes measurements around the clock, it was easy for Cushman & Wakefield staff to develop and understanding of the issue areas and what was driving low performance.

Hux enabled the client to avoid many thousands in additional fees from consultants and specialists, while also giving them much better data on which to make turther decisions.

Special Focus: Ventilation

Hux is the lowest cost solution available for precision carbon dioxide measurement, with CO2 sensors already part of our solution suite, it was easy for the client to expand their insights into air quality

Effortless CO2 monitoring

Key insights for the Cushman team was alleviating concerns they had in some of the higher density areas that there might be elevated carbon dioxide levels - Hux was able to show that the building never exceeded best practice thresholds
