Weatherization and Energy Efficiency Improvement for Existing Homes: An Engineering Approach
Features
- Presents a systematic approach to energy analysis of building energy performance
- Describes state-of-the-art energy efficiency techniques
- Includes simplified calculation methods for evaluating effectiveness of various efficiency measures
- Addresses other aspects of retrofitting existing homes, including improving thermal comfort and indoor air quality
- Offers practical examples and case studies
Summary
Providing a proven set of energy efficiency measures and opportunities for saving energy and reducing operating costs for existing homes, this volume presents general tools and procedures for performing home weatherization such as insulation improvements as well as methods to reduce air leakage. The author describes several techniques and technologies that can reduce energy use or operating costs, including methods to retrofit existing homes to be net-zero energy buildings. Each chapter contains simplified calculation methods used to evaluate the effectiveness of various efficiency measures. The final chapter offers a series of case studies including examples of weatherized homes.
