The house that slashed its energy bills by 70 per cent
The interior is demure, in soothing, earthy tones. The air is warm, and it is quiet – so quiet that the noise generated by the construction site next door has ceased to exist. While roomy, townhouse number 3 (the rest are occupied) isn't huge, but it is comfortable.
There is nothing obvious that signals the development is premium, other than its address in Hawthorn, and price tag of $2.5 million plus.
And yet, it is Australia's first build-to-sell Passivhaus development, called ECHO.1, a proof-of-concept project by C.Street Projects and Neil Architecture that aims to show that incredibly energy-efficient homes can be built, at scale, in Australia.
Kin Seng Choo, C.Street Projects director, also wants to prove that the private market can contribute to the decarbonisation of the building sector, which accounts for a fifth of greenhouse gas emissions worldwide.
'A three-bedroom house would normally consume about 18,000 kilowatt-hours per year, while the passive house should consume about 5000 kilowatt-hours per year,' says Choo. 'This means the house is using about 70 per cent less energy than a typical Victorian home, with a typical annual energy bill of about $700 to $800.'
Passivhaus, which translates as 'passive house', is a housing performance standard conceived in Germany in the 1980s by physicist Dr Wolfgang Feist and construction expert Professor Bo Adamson.
The concept, which took its cues from ancient dwellings such as turf houses built in Iceland during the Middle Ages, optimises insulation and the airtightness of the building envelope to stabilise the internal temperature.

'Battery of the nation' undersea power cable at risk
One of the nation's largest energy projects could be in doubt amid a government stoush and a cost blowout. The multi-billion-dollar Marinus Link undersea power cable project to connect Tasmania to the mainland has been touted as critical to making the island state the "battery of the nation" by increasing its capacity to export green power. The $5.5 billion project is set to be funded by the federal, Tasmanian and Victorian governments. The Tasmanian government's decision on its 17.7 per cent share of the link's Stage 1 cable, initially promised by July 31, has been delayed. Tasmania's Shadow Energy Minister Janie Finlay on Saturday accused Premier Jeremy Rockliff of blocking a briefing from Energy Minister Nick Duigan on the Marinus business case. It had been hoped the briefing would create bipartisan support to secure the project as Tasmania's Liberal government scrambles for survival following the July 19 election. "We are days away from a critical decision on one of Tasmania's largest infrastructure projects," Ms Finlay told reporters. "The business case has been sitting in the premier's office for two months, but Jeremy Rockliff won't let Tasmanians see it. "Not only have they just not briefed Tasmanian Labor, but the premier has stepped in and actively blocked that." Tasmanian Minerals, Manufacturing and Energy Council chief executive Ray Mostogl said the delay and uncertainty placed the entire project at risk. Marinus Link must "issue notice to proceed" by the end of August or lose a $1.07 billion contract with the Italy-based Prysmian Group to supply the 345km cable. Tasmania's Liberal government is in caretaker mode after the state election delivered another large crossbench, some of whom oppose the Marinus project. Ms Finlay accused the Rockliff government of hiding the Marinus Link business case for political gain because it included significant price impacts to pay for transmission infrastructure. The government has denied Mr Rockliff or his staff blocked a briefing, saying the opposition would be briefed in line with caretaker conventions. "We are carefully and methodically working through the details, with a decision expected soon," Mr Duigan said. The undersea electricity and data connector would link Tasmania's northwest with Victoria's Latrobe Valley and allow the smaller state to import surplus solar while exporting hydropower to the mainland grid, where it could help reduce the risk of brownouts. The project was scaled back in September 2023 after the cost of two cables blew out by $1.7 billion to an estimated $5.5 billion. Under the plan, Victoria has a 33.3 per cent share and Tasmania 17.7 per cent, with an option to sell its stake to the Commonwealth on completion. Marinus Link has been touted as a critical component in making Tasmania the "battery" of the nation by increasing the island's capacity to export green power and allow excess energy generated on the mainland to be stored in Tasmania's hydro storage. The first stage is not slated to be finished until 2028/29. One of the nation's largest energy projects could be in doubt amid a government stoush and a cost blowout.

Monique wants to buy a house in Melbourne's inner suburbs, but she may have to be quick as the city's property prices are on the march. Analysis Victoria residential property Abundance has captured the attention of economists and politicians alike, but could a simple solution be sitting right under their noses? The well-loved house attracted bids from four interested buyers, but a bold approach from the winner fended off the competition after fewer than a dozen bids. Most Melbourne home owners sell up within 10 years, but there are some suburbs where residents stay for decades. The Victorian was liveable, but had the scope to be extended. Auctioneer Josh Kalender said the home's potential inspired two bidders to compete for the keys. Victoria residential property Melbourne's asking rents sit at record highs and some suburbs have recorded annual increases of more than 20 per cent. An attractive price guide tempted seven bidders to try their luck at auction on Saturday. Agents say the home's liveability, and its location inspired spirited bidding. Profits for home sellers have increased by hundreds of thousands of dollars in the most popular regional areas over the past five years. A new report has revealed where buyers can find a home cheaper than the city's median price without compromising on what makes an area liveable.
