Webinar Series: Sustainable Energy in Humanitarian Settings
Productive Uses of Energy (PUE) in Humanitarian Contexts - This webinar will provide an overview of different types of PUE activities in displacement settings, followed by two case studies from Kenya and Rwanda. SELCO Foundation will introduce the topic and Practical Action and Energy for Impact will then share their experiences and lessons learned from Rwanda. SNV Kenya will discuss their market-based approach from Kenya. Read more...

In 1997, Tianjin introduced its first mandatory residential BEEC (identified as DB29-1-97), which is equivalent to the requirements of the JGJ 26-95, the national model BEEC for cold climate regions enacted in 1995. DB29-1-97 was enforced from 1998 to 2004. Enforcement actually began on January 1, 2005; it was based on an earlier version which was updated and reenacted on June 1, 2007. This case study covered five years of enforcement of DB29-1-2007, from 2005 to 2009.
From 2005 to 2009, about 70 million m2 of new residential buildings were completed in the urban areas of Tianjin. Many were subject to compliance of DB29-1-97 because their construction permits were issued before January 1, 2005. About 50 million m2 of them were designed according to Tianjin’s DB29-1-2007. This puts the upper range (assuming full construction compliance) of the calculated space heating energy savings of these new buildings at about 870 GWh/year, compared with the baseline of complying with DB29-1-97 (or the national JGJ 26-95). Heat energy saved would be sufficient to provide winter space heating for about 200,000 apartments (at 100 m2 each) built to comply with DB29-1-2007. Compared with the baseline, the estimated simple payback period for compliance with DB29-1-2007 based on avoided cost of heating service is less than seven years, attractive even if the energy efficiency (EE) measures have a lifespan of 15 years.
