Making roofs more intelligent

What’s being billed as the country’s first zero energy house is steadily taking shape in Point Chevalier, Auckland, and its owners are aiming to save up to $80,000 in power costs over the next 25 years.

Zero energy house leading the way
By Idealog
SolarCity has partnered with owners Joanna Woods and Shay Brazier and energy consultants and eco-companies to help build the house, which aims to achieve net-zero power bills by generating as much electricity as is consumed through a blend of energy-efficient features and an intelligent solar roof. Brazier, who is also head of design and innovation at SolarCity, says the house could save between $50,000-$80,000 in power costs over the next 25 years.
“Our zero energy house protects us from the impact of electricity rate increases while safeguarding the environment for the next generation,” Brazier says. “The country needs to start thinking about making their roofs more intelligent, and start thinking about the cost of running a house per square metre, rather than just the cost of building a house per square metre.”

Team New Zealand’s Solar Decathlon House Puts an Innovative Twist on the Basics
By Amanda Coen
This year’s Solar Decathlon home design competition saw many fresh takes on the solar-powered prefab home, but Team New Zealand stood out from the pack with its elegant, light-filled, wood clad home. Built by students from the Victoria University of Wellington, the beach house inspired First Light home has a breezy, open feel with the invigorating smell of freshly cut cedar planks emanating throughout. This seemingly basic but surprisingly innovative house is currently on display at the 2011 Solar Decathlon competition on the National Mall in Washington DC.

Several unique features set the house apart from the rest. Inspired by the traditional New Zealand holiday home, the “Kiwi bach”, socialising and a relationship with nature were of prime importance in the design process. The front and back bi-folding doors allow for plenty of natural light to enter. An overhanging roof provides ample shade on hot days while also adding protection when the doors are open, creating a seamless unification of the interior and exterior environments.

Energy Roof Perugia, Italy

Eco Factor: Self-sufficient structure generates solar and wind energy.

Coop Himmelb(l)au Energy Roof in Italy
By ridhika db
Wolf D. Prix, design principal and CEO of Coop Himmelb(l)au presented the design for the ‘Energy Roof’ in Perugia, Italy, today.

Energy Roof is part of a research project for the University of Perugia called, “Walking through the history”. The roof serves as canopy along Via Mazzini in the centre of Perugia and at the same time creates the entry point to the archaeological underground passage leading through the history of Perugia.

The architect developed the design of the roof with the goal to generate energy for the city. While the orientation of the west wing is optimised in relation to solar radiation, the east wing captures wind. The roof consists of three layers: the energy generating top layer, the structural layer in the middle and a layer on the bottom as a combination of laminated glazing and translucent pneumatic cushions.

The top layer includes transparent photovoltaic cells to generate electricity and shade the sun. The orientation of the individual cells is generated and optimised by a computer-driven scripting programme. Furthermore five wind turbines placed inside the structural layer are generating additional energy. Both the roof and the underground passage are energy self-sufficient.

The new paradigmatic design of the Energy Roof creates a distinctive and highly recognisable icon for the city and a statement for aesthetic sustainability corresponding with the ancient buildings of Via Mazzini. -David K.
