Bottleyard Apartments – North Perth

The Bottleyard Apartments on Palmerston Street are another example of a development striving for sustainability under the City of Vincents’ planning requirements. The apartments will be located beside Robertson Park, just 5 minutes by bus (or bicycle) from Perth city. They incorporate renewable energy technology, clever energy efficiency measures for individual apartments, common areas, and a long design life.

The development offers 125 one and two bedroom luxury apartments offering a sustainable city location with local amenities including restaurants, parks and amenities just a few minutes by bike or foot.

Project features

Design life

The Bottleyard apartments consist of 125 high quality design apartments located on Palmerston Street halfway between Northbridge and Mount Lawley and within 5 minutes bus ride or cycling of the city. High density and future proofing architectural design gives an estimated 130 years design life in eTool. The estimated occupancy for the whole development is 207 occupants divided into 1, 2 and 3 bedroom apartments.

Energy Efficiency

eTool have been appointed during the early planning stages of the project  and have highlighted a number of areas that offer easy wins. The apartments are designed to ensure good cross-flow ventilation and natural lighting penetration.

Common Energy Use

Multi-residential apartment buildings have high demand for electricity due to common lighting, car park lighting, car park ventilation and lifts. Electricity costs can have a significant impact on occupants’ strata fees if an intelligent design is not implemented. The apartments incorporate motion sensors with automatic timers to prevent unnecessary electricity consumption when car park is not in use.

Car park ventialtion can also contribute significantly towards a buildings energy consumption due to the electricity consumption of the intake and extract fans. The car park at the Bottleyard will be predominatly naturally ventilated cutting down on fan runtimes.

Renewable Energy

The 4 storey development meets the golden ratio in terms of roof space available per apartment. An extensive 260kW solar PV system will comfortably fit on the flat roof that offsets a large proportion of the apartments and common electricity use. Developments built to 5 plus storeys tend to have proportionally less roof space available for PV per apartment and hence have a smaller practical opportunity to off-set their electricity consumption.  That said, there are obvious indirect carbon savings to building higher density such as ease of transport.

Continuous Engagement

eTool have continued to engage with Handle property group by running a sustainability workshop for the sales and marketing teams. This ensures everyone has a good understanding of the sustainability features involved and is able to communicate them clearly to potential buyers. This is viewed as a crucial step in gaining marketing advantage and spreading the sustainability message across the industry.
