Meet Angel Carrillo (left) and Santiago Naudon (right). Angel and Santiago are both architects – architects with a major green bent. After the meeting last week these two likeable and enthusiastic fellows have been drawing up design plans to create the two new demonstration homes for the El Manzano community.
Miguel (again, see last week’s post) will be first to see his house get built. Rather than dictate design ideas to Miguel, Angel and Santiago worked with him over a few days, showing drafts and making recommendations, until a final design plan emerged.
Santiago, Angel and Miguel discuss plans at Miguel’s house site
The resulting plans (see diagrams at bottom), are an attempt to find a happy balance between minimising environmental impact (creating a home with low ongoing energy demand and using materials sourced as locally as possible), minimising cost (both because of minimal secured funds and also to ensure the structure is feasible for most Chileans) and creating a home that is both highly comfortable and strong enough to take the worst Chile’s earthquakes can throw at them.
After the plans were completed they were shown to the builders put in charge of the construction process.
Angel explains the design to the builders
Some of the design features include:
- aspect to maximise winter sun and increase summer shade
- fire in centre
- wet back fire (heats water). The house may have a solar hot water heater, if funds allow
- Made primarily of straw and light clay – flexible materials (high straw content) and excellent insulation
- Timber frame, which makes the house flexible for earthquakes
- low roof for faster heating
- 25cm window sills made of stone, to absorb heat during the day and give it off again in the night. Eaves are designed so that only the winter sun will reach the stone sill
- front door in north, back door in south – when both opened in summer it will create a cross-flow to draw cool air through the house
- Capacity to take a green roof
The house site, with new house positioned for sun
Designed for single occupancy, but allowing for guests to access sanitation
facilities (left) without needing to go through Miguel’s bedroom (right). Visitors
can access through the rear of the house. Bedroom window gets morning sun,
living room throughout the day.
Roof designed to be able to host a green roof. Eaves the right length to
protect from hot summer sun, but to open home to winter rays.
