Project Summary
Elevator Pitch

Concise Summary: Help us pitch this solution! Provide an explanation within 3-4 short sentences.

The Passive House Prototype features affordable housing that uses 50 - 75% less energy than houses in a similar location. They are attractive, compact and sustainable, and can be constructed in 12 weeks. They represent a powerful opportunity for decent home ownership for those who had no prior hope.

WHAT IF - Inspiration: Write one sentence that describes a way that your project dares to ask, "WHAT IF?"

What if all people could afford to own their own beautiful homes that generate all the power they need...and then, some?
About Project

Problem: What problem is this project trying to address?

Most developing countries have housing deficits. Many countries struggle with power, clean water, improved sanitation, poverty and unemployment issues. Nigeria struggles with a 17 million-unit housing deficit, unreliable power, and low access to clean water and improved sanitation. Unemployment is high, and home ownership is low. Slums abound and decent low-cost housing is scarce. Affordable green housing is desperately needed to address these.

Solution: What is the proposed solution? Please be specific!

The affordable Passive House Prototype (PHP) is an innovative simple solution that boldly attempts to address these complex social, economic and environmental interwoven challenges. The PHP features a building prototype of four 1-bedroom units arranged around 2 courtyards. The units are attractive, compact, naturally lit & ventilated and use bio-climatic design to be energy efficient. The PHPs are designed with cool roofs, wide overhangs, large windows, locally available materials, compressed earth blocks (for high thermal performance) and solar panels. Rainwater is harvested and recycled where possible, and the courtyards foster community within occupants. Widespread construction of these housing units will create training and employment.
