HVAC central
to redesign of built environment
HVACR PROFESSIONALS WILL NEED TO GET THEIR GREEN CREDENTIALS IN ORDER TO DEAL WITH THE CURRENT COVID-19 ENVIRONMENT WHICH IS SET TO LEAD TO A RADICAL REDESIGN OF THE BUILT ENVIRONMENT.

transform the city skyline and is the most de- tailed planning review of the CBD in more than four decades.
The draft Central Sydney Planning Strategy will be on exhibition until early July.
“This strategy is the product of three years of deep research, block by block, carefully examin- ing the way the city works and where sunlight falls,” she said.
The goal for HVACR professionals is to find so- lutions that thrive in this new environment.
For example, buildings may be getting taller but HVAC plants are shrinking which is why
“IT IS THE MOST DETAILED PLANNING REVIEW OF THE CBD IN MORE THAN FOUR DECADES..”

Temperzone’s CWP901 R32 Inverter (vertical water-cooled packaged unit) is such a good fit for this new landscape.
The CWP 90 is designed to run on an individ- ual power supply, eliminating the need to install expensive central plants. Being internally in- stalled packaged units, they are perfect for many installations where the use of balcony units are prohibited.
With the use of an inverter compressor com- bined with an electronic expansion valve the CWP 90 ECO ULTRA provides a precise load var- iation response and superior part load perfor- mance for closer comfort control and higher en- ergy efficiency.
Temperzone’s group brand manager, Damien Walsh, said it also features new ThermoShell Technology that has taken the unit’s green cre- dentials to a whole new level.
Unlike coaxial and plate-type heat exchang- ers, Walsh said ThermoShell prevents degrada- tion in heat transfer efficiency due to water foul- ing, facilitating reliable operation throughout the unit’s service life.
“It also enables considerably lower water flow rates and water pressure drops to be accommo- dated by the system, with minimal effect on duty and efficiency,” he said.
“This leads to operational savings as well as pump power savings up to 36%, and a 20% reduc- tion in carbon emissions.”
Water scarcity is a serious issue for cities with the UN's 2020 World Water Development Report pointing out that water use has increased six- fold over the last century and is rising one per cent every year.
The World Bank predicts by 2050 demand for wa- ter will increase 55% due to urban populations. ✺
ARENEWED FOCUS on occupant health and well-being in building de- sign will extend to every aspect of ther- mal comfort from air quality to light- ing, ventilation, water efficiency, and of course, reduced carbon emissions, just to name a few.
Design will need to undergo a complete re- think and central to this shift will be HVAC.
University of NSW Associate Professor of the Built Environment, Paul Osmond, said this shift will go beyond buildings to encompass cities and entire neighbourhoods.
“The question is, how do we draw lessons from this pandemic to design houses, office buildings and cities in a way which makes us more resilient to future pandemics, while also being more peo- ple-friendly?” he said.
“Future building design will be about mini- mising energy use, acknowledging climate change and understanding how we can live a lot healthier and happier in the future.”
With urban populations spending more time indoors, Professor Osmond said the focus will be on ‘living architecture’ such as green roofs and walls, more sunlight and ventilation.
“We need nature, at a minimum for viewing, but ideally through immersion and interaction,” he said.
“Being surrounded by nature improves the immune system, and a person’s physical and mental health by alleviating issues such as stress and anxiety.”
According to the United Nations (UN) 68% of the world’s population will live in urban areas by 2050. It is a trend that has been clearly evident in Australia’s major cities including Sydney and Melbourne.
The first city in Australia to respond to this design shift is Sydney with the city council an- nouncing a new strategy for buildings more than 300m tall.
