Assessment of the Technical Potential for Micro-Cogeneration in Small Commercial Buildings across the United States

Jump to: navigation, search

Overview

This paper presents an assessment of the technical potential for micro-cogeneration in small commercial buildings throughout the United States. The cogeneration devices are simulated with the computer program EnergyPlus using models developed by Annex 42, a working group of the International Energy Agency's Energy Efficiency in Buildings and COmmunity Systems (IES/ECBCS)/ Although the Annex 42 models were developed for residential applications, this study applies them to small commercial buildings. The potential for micro-cogeneration is examined for the entire exisitng stock using a bottom -up method based on 1,236 EnergyPlus models. Technical potential for micro-cogeneration is characterized by adding micro-cogeneration to individual baseline building models and quantifying the changes in a variety of whole-building area-normalized, performance metrics including site energy, source energy, and energy cost.

Highlights

This paper explores and identifies microgeneration devices for residential uses and applies them to small commercial buildings. The building stock data for small commerical is significant within the US and this resource details the potential for micro-cogeneration for the commerical sector. Cogeneration is an efficient way to capture waste heat and redirect it. This aides in both energy efficiency measures as well as environmental benefits.
