Fig. 7.9 Outline of the design process of ÉcoTerra
Once the architect was provided with the approximate geometrical details,
heprovided some preliminary drawings tothe engineers. Prior tothe design
charrette, the appliance, lighting, and plug loads were estimated using a
bottom-up approach, whereby energy consumption of each appliance and
other electricity-consuming item was predicted.

It involved about 10 experts, including the lead engineer and architect,
graduate students, the builder, a representative from the local municipality,
and several technology experts. From the charrette, several key features of
the design were identified, including
1. A direct gain passive solar design combined with a well-insulated,
airtight envelope;
