USAID Enterprise Energy Efficiency – 3E Pilot Project Proposal No. B2-2

B2-2 aims to reduce thermal losses in a low-income housing apartment building in Rogatica, Bosnia and Herzegovina. The project involves the thermal insulation of the building facade, installation of energy-efficient light bulbs, and individual heating furnaces for each apartment. The building design has a favorable form factor, which reduces specific energy consumption, and the windows will be double glazed to further reduce energy consumption. The project is a collaborative effort between the U.S. Embassy in BiH, Hilfswerk Austria, the RS Ministry of Refugees and Displaced Persons, and the Municipality of Rogatica. The USAID 3E Project will finance the thermal insulation of the building, which is in line with the requirements for the climate zone. The estimated heat loss through the facade walls, with and without thermal insulation, is shown in Table 1. The reduction of CO2 emissions achieved by thermal insulation will be 20-25 tons per year. The cost for the measures and the payback period is shown in Table 2. The thermal insulation of the building facade is estimated to cost $22,000 and will result in annual savings of $3,500, with a simple payback period of 6.28 years. The installation of energy-efficient light bulbs is estimated to cost $2,000 and will result in annual savings of $1,000, with a simple payback period of 2 years. The project is expected to demonstrate energy savings and improved thermal comfort through thermal insulation and good quality windows. It will also stimulate local economy and building practices, increase awareness of the local governments of the benefits of thermal insulation, and increase awareness of building owners that they are responsible for the maintenance of the whole building. The project has a high level of replicability potential and relative ease of implementation, with a total score of 90% out of 100%. The project also has a high level of readiness and ability to put in place clear monitoring and verification procedures for reporting on post-implementation energy savings. The project is expected to be completed by September 30, 2013, and will be evaluated based on its technical and financial performance. The project will have a positive impact on the environment by reducing the usage of coal and wood for heating and reducing CO2 emissions. It will also improve public health by reducing the negative impacts of poor indoor air quality. The project will also increase awareness of energy efficiency among building users and citizens at large, which may lead to new regulations related to energy consumption in buildings and financial support of local governments for such projects.
