The zero net energy home (ZNEH) market is just beginning to emerge. Building codes are evolving to require increased residential energy efficiency, onsite generation is proving useful in tackling grid load, and the latest technologies are becoming more mainstream. Near-zero net energy (ZNE) and ZNE-ready homes are also becoming increasingly accepted as builders make an effort to offer enhanced efficiency options to meet higher standards and satisfy energy-conscious consumers. A ZNEH is generally defined as a building where the amount of energy produced onsite is equal to the amount of energy consumed annually. California is leading the drive toward ZNEHs worldwide with its goal of 100% of newly constructed residential homes to be ZNE beginning in 2020. However, other states in the United States and other countries in select regions, such as Europe and Asia Pacific, are also beginning to follow suit with ZNE initiatives and energy efficient building codes. Although still nascent, the market for ZNEHs is expected to be led by new construction in North America. Navigant Research expects total units in the region to grow from 750 in 2015 to nearly 27,000 in 2025. This Navigant Research market data report examines the global market for ZNEHs in three categories: ZNE, near-ZNE, and ZNE-ready. The study provides an analysis of the drivers and barriers of the ZNEH market and highlights several case studies. Global market forecasts for units and revenue, segmented by category and region, extend through 2025. The report also provides distinct market definitions for the different categories and examines the key regional market trends related to ZNEHs.
