The €100,000 sustainable home?

The €100,000 sustainable home?

Mario Cucinella architects have produced an interesting theoretical prototype for a low cost sustainable home, dubbed 'Casa 100k'.

"The project is an attempt to find an effective solution to the issues of affordable costs, low pollutant emissions and genuinely attractive housing," the company says.

"The house has a bright, lively design that readily adapts to the needs of different residents and lifestyles, as well as producing energy through a series of passive and active strategies that make it an efficient bioclimatic machine."

The 100 square metre house is estimated to cost €100,000, and feaures integrated solar PV and timber frame construction. "Low construction costs have also been achieved by using a light, flexible form of prefabrication, including structural elements, technical systems and mobile components such as sliding, removable and bendable wall panels/partitions," the company adds.

As you'd expect, the south facing aspect of the building is extensively glazed. Roof gardens and greeneries feature prominently, and each unit boasts a whopping 35 square metres of solar panelling (all PV presumably, but this isn't clear on the official website) which helps to power ground-source heat pumps. Rainwater harvesting also features.

Depending on the climate, the designers claim the buildings could be net producers of energy.

How can a north facing PV system create efficiently energy?
".....series of active and passive energy-saving strategies. A typical unit is designed with its most compact façade facing North and its most complex façade facing South...."
The PV panels are facing north since they're roof mounted, supposed to be creating a surplus of 500 kwh per year(after heating and cooling is subtracted). How can a 100m2 household be run on 500kwh per year?
Each unit is supposed to have 35 m2 of PV panels, but there is only 1 roof of this size for several units to share since these are multy storey appartment blocks shown on the plans..... There seems to be a calculation error.
All PV panels are severly put under stress when placed at the rim of a roof(wind load). All manufacturers are warning of this installation method, no insurer would cover such a method. So only a smaller space as the roof itself can be used to install them.....with some walking space for servicing left free as well. And no shading from propellors please!
35m2 of PV panels installed and comission will cost about €20,000...and what is for the house left? A propellor for €5,000, a heatpump system for €10,000, air conditioning and ventilation, rainwater harvesting... Hey, that leaves enough money for a dustbin!
Sorry, these are the type of news not published elsewhere.....
