Louise Braverman's plan for this 40-acre medical campus in Burundi, contracted by the nonprofit organization Village Health Works, includes a 29,000-square-foot women's health center, staff residences, and several other facilities. Though operating rooms require HVAC , the New York'based architect designed most of the buildings on site to be naturally ventilated, and the complex will produce its own electricity with photovoltaics and other energy sources. Phase one of construction'the staff residences'is scheduled for completion this fall.
