This publication, commissioned by the UNDP-supported GEF-funded preparatory project Market Transformation for Sustainable Rural Housing in Uzbekistan, presents an analysis of the energy-efficiency potential and expected financial benefits of enhanced house designs of the State Programme.  This analysis indicates that energy savings of about 25 percent are achievable at an incremental cost of less than three percent, with long-term savings for homeowners.  The publication also analyzes scenarios for green mortgage financing that would help to ensure the initial affordability of green rural housing designs.  The publication concludes with general recommendations on how to promote integration of green designs into the State Programme, with a summary of broader social, economic, and environmental benefits.
