Technical CorePrefabricated energy management system

Includes kitchen, bathroom, mechanical room and associated system controls and

plumbing

Makes construction safer, cheaper and easier

Solar PowerPhotovoltaic Modules

Outputs energy as DC electricityDC is converted to AC using an inverter

Conversion losses can be as high as 10%

Mitsubishi Electric Photovoltaic Modules

Not actually part of the technical coreNecessary to power it and the home

We recommend the Mitsubishi Electric TD175MF5

Unimplemented ConceptsGreen Roof

Too unsightly and potentially high maintenance

Too farfetched for a marketable home

Consolidate all high energy using appliances to reduce transmission losses

Electrical losses too insignificant to warrant the inconvenience
