Using Energy Audit Methods and Computer-Based Modeling to Develop Energy Efficient Building Retrofit Strategies for Universidad Don Bosco
(Editorial Universidad Don Bosco, 2013-11) Riedel, Nicholas
This article presents multiple retrofit solutions to reduce energy consumption in the buildings of La Universidad Don Bosco (UDB) campus in Soyapango, El Salvador. This article identifies the critical energy losses in three energy intensive UDB campus buildings by means of energy audit practices and computer-based modeling. Specific energy saving retrofits were developed using the building simulation software eQuest. Multiple retrofit options are developed to provide university administrators with flexibility in selecting the most appropriate solutions based on their budgetary constraints and energy efficiency goals. The three most favorable retrofits investigated were: (1) reducing infiltration rates in Edificio Dos, (2) implementation of a cool roof for El Taller Mecánico, and (3) upgrading to SEER 13 cooling equipment in El Taller Mecánico. These retrofits are expected to save 4.0 MWh/year (1), 5.5 MWh/year (2), and 28.9 MWh/year (3) respectively and the discounted payback periods are forecasted at 7.1 years (1), 7.7 years (2), and 7.0 years (3), respectively.
