Abstract
Housing retrofit can reduce energy consumption and decrease long-term costs associated with the operation of a building. The objective of this study is to introduce an approach for evaluating energy-efficient housing retrofit alternatives, using data from a real case. A detailed life-cycle cost analysis (LCCA) of possible retrofitting strategies is performed for the case of a house built in the 1960s in Albuquerque, New Mexico, USA. Based on this case study, an approach is developed to illustrate the impact trend of retrofitting costs on energy consumption savings. By defining three separate cost evaluation zones, comprising of a cost effective zone, an energy efficient zone, and an improvement needed zone, the results of this study can potentially be used not only in decision-making for retrofitting, but also in the evaluation of projects related to energy retrofits. Then, using the proposed methodology for the case study, a normalised model is developed to evaluate the effectiveness of retrofitting effo...
期刊介绍:
The International Journal of Sustainable Building Technology and Urban Development is the official publication of the Sustainable Building Research Center and serves as a resource to professionals and academics within the architecture and sustainability community. The International Journal of Sustainable Building Technology and Urban Development aims to support its academic community by disseminating studies on sustainable building technology, focusing on issues related to sustainable approaches in the construction industry to reduce waste and mass consumption, integration of advanced architectural technologies and environmentalism, sustainable building maintenance, life cycle cost (LCC), social issues, education and public policies relating to urban development and architecture .
