This document proposes several low-cost and sustainable housing solutions that are energy efficient and use local materials and resources. It discusses utilizing a square grid pattern design, cavity walls like rat traps for insulation, interlocking wall blocks made from fly ash and brick dust, insulated RCC filler slabs, various pyramid roof designs using compressed bricks or diagonal bricks that require little or no reinforcement, and waste cement bags. It also proposes using green bricks baked with poultry waste instead of coal, and generating electricity and fuel through pyrolysis of agro-waste to produce producer gas. The overall aim is to provide affordable green housing through appropriate design, technology, and resource mapping choices.

Resource Mapping
•Local Availability of building
Materials.
• Manpower.
•Geo-Climatic Characteristics.
•Vernacular Architecture.
•Economics.
•Scalability

3. Design: Square Grid Pattern Design
Design: Square Grid Pattern Design

4. Technology: Cavity wall like Rat-Trap
•Reduces cost •Enhances Insulation
Technology: Cavity wall like Rat-Trap

5. Interlocking wall blocks
•Made of fly-ash, Stone dust, Brick dust
•Good for exposed walling •Maintenance free
•Reduces weight of structure
•Reduces cost
Insulated RCC Filler Slab
Reduces structural cost and provides Insulation

6. Ferro-cement Pyramid
•Low cost •Locally available materials
•Best for resorts and Hotels
Compressed Brick Pyramid with Top ring
beam on wall
•Roof span up-to 25 feet
without reinforcement
•Required slope is
just 5 to 15 inches
•Best for School Buildings, Community halls etc.
•Significantly lower cost
•Less Impact on
Environment.

7. Diagonal Brick Pyramid
This can be constructed without beamZero Iron Structure
Cost Effective Construction
Waste Cement Bag
•Pilled one above other
•Cement bag filled with waste sand and 5% cement
•Low cost
•Best suited for monumental structure and rural housing

8. Green Bricks
•Casted as normal brick
•Baked not by coal but by poultry waste
•Bacterial treatment of poultry waste
on source reduces the pathogenicity
And odor of poultry waste.
•Low cost
•Less Impact on
Environment
•Calorific value of poultry waste
is normally 60-70% of coal
•After burning Poultry waste it generates
ash, rich in phosphorous, Potash,
Calcium, Magnesium, Zinc etc.
•It acts as a very good fertilizer.
Energy: Electricity And Fuel
•Pyrolysis of agro-waste to generate producer gas.
•Low cost green solution for electricity generation.
•Producer gas can be used directly for cooking food &
electricity Generation
