Affordable Housing - How To Succeed

1. Stop complaining about the price of cement.  Start Digging.   
Wise civilizations have always built homes with what they have, not with what they have to obtain with difficulty.  Today's Nigeria is not a wise civilization I suppose, or we would use laterite bricks more. 
What is laterite?  The answer may be beneath your feet at the construction site.

2. Build more units than you need
Sell or rent to others, and make some money.  Be an answer to the housing crunch...Nigerians need answers.  Do you want to become an expert in affordable and sustainable building technology?  Start here.

Meet the experts, read their books and study their works, for example The Architecture of Renowned Master Demas Nwoko

3. Lower your running costs too
Fire NEPA/PHCN/xxDC , throw away the noisy generator (or give it to your enemy lol) and be your own solar power provider.  Also remember to build in time-tested natural ventilation and passive cooling systems from day 1, from the first drawing your architect makes.       

Thermal ventilation and Cross-ventilation

Get inspired: See more natural heating and cooling systems via snelhai's pinterest page

Ventilation Blocks

We can learn a lot about Passive Cooling from Cairo/Egypt, Yemen/Arabia, Iran/Iraq, and the Middle East in general.  Example: E.M. Okba (Cairo University) has notes on Building Design for Passive Cooling

Middle Eastern - style wind tower for ventilation

Traditional Badgir (wind-catcher) system

Apply wisdom.  Come back with a testimony.

Quagmire in the Sahara: Desertec's Promise of Solar Power for Europe Fades

SPIEGEL ONLINE - November 13, 2012 As recently as three years ago, many thought that it was only a matter of time before solar thermal plants in North Africa supplied a significant portion of Europe's energy needs.

Merkel's Blackout: German Energy Plan Plagued by Lack of Progress

SPIEGEL ONLINE - October 10, 2012 Germany plans to abandon nuclear power by 2022, but its government hasn't been doing enough to ensure that the project succeeds. Needed infrastructure and technology is lacking, and coordination is a mess. Meanwhile, weary consumers are paying more for electricity, and the supply is in jeopardy. By SPIEGEL Staff more...

Flexible Fossils: A New Role for Coal in German Energy Revolution

SPIEGEL ONLINE - September 07, 2012 One of the biggest challenges of Germany's ambitious energy revolution is the fact that renewables such as wind and solar are subject to large fluctuations in output.
