City of Parramatta manager Helen Papathanasiou intends to future proof Paramatta’s quickly developing built environment with the use of planning controls.

The council is mandating the use of piping for recycled water to be placed in every single category of development in the CBD, and energy and water saving targets as much as 25 percent above state government BASIX levels for certain developments.

To defeat the urban heat island effect, the council is making an effort to better comprehend the manner in which glass facades contribute to warming outside the building and on the street.

The council also aims to ready for the impended influx of electric vehicles by ensuring that charging equipment can service the majority of car spots.

Papathanasiou addressed The Fifth Estate’s Tomorrowland 2019 event, saying that planning controls are needed to contend with the inertia experienced when local governments are planning for a city’s tomorrow.

She said at the City of Paramatta, officials are considering planning controls. She asserts that the mandating of recycled water piping in new developments has served as a coup.

Recycled water providers are not at this point able to serve the community, but the council aims to facilitate this in the near future. In general, she aims to make communities—and longstanding buildings–more sustainable.

The council also is establishing higher mandatory energy and water saving targets, increasing energy efficiency targets by 25 percent on top of government targets for structures of 5-15 storeys and giving floor space incentives.

These energy targets are different for each building, with lower targets set for higher buildings. This is due to the fact that the taller the building, the more energy is required to pump water up to heightened levels and operate lifts.

Papathanasiou said that structures come complete with a “sweet spot” for energy performance at between 5 and 15 storeys.

In addition, The City of Paramatta is investing in urban heat development controls, anticipated to be released as a component of its new development control plan (DCP).

The city is collaborating with energy consultants to comprehend the manner in which facades heavy with glass exacerbate the urban heat island effect.

Part of the difficulty takes the form of changes to the energy efficiency rules stated in the building code, which has inspired glass manufacturers to manufacture more efficient glass.

This glass might deflect heat from the building, but it reflects heat back onto the avenues outside.

This is an issue at the ground plane level, says Papathanasiou, as at elevated levels the wind is stronger and transports the heat away.

Solutions under consideration include the mandating of roofs painted green or white.

Certain structures might be mandated to include shading to minimise reflectivity with the use of vertical or horizontal fins, or another variety of high-tech façade treatment.

As the community grows, it is likely to include more vertical surfaces as opposed to horizontal.

The Greater Sydney Commission also has a plan for a more walkable city and a 30-minute city, which will reduce work commutes.

Papathanasiou says that regional governments face so many competing interests that sustainability considerations are sometimes neglected. Yet the Department of Planning has granted gateway approval for the Local Environmental Plan, with final approval pending. And the state government has signaled a recycled water treatment system to serve this area.

Papathanasiou told Tomorrowland that the council is very eager to collaborate with governments at other levels, to plan for their own Tomorrow.
