Identifying Research Gaps in Implementation of Zero Energy Building (ZEB). Chayanika Mitra Virginia Polytechnic Institute and State University, Blacksburg, Virginia. Annie. R. Pearce Virginia Polytechnic Institute and State University, Blacksburg, Virginia Literature Review OBJECTIVES Identification of: METHODOLOGY Research Gap 1. Research opportunities in context of ZEB. 2. Barriers in implementation of ZEB, based on content analysis. 3. Factors positively facilitating the adoption of ZEB among consumers. Identification of Literature • Sustainability • Innovation • Construction PROCESS OVERVIEW Mapping Gap Analysis Innovation Constructio n Content Analysis STEP 2 : Content Analysis Sustainability • Identifying barriers • Identifying barrier breakers • Identifying drivers • Barriers with Barrier breaker • Barriers with Drivers • Identify research gap INITIAL LIST OF LITERATURE No. Research Title Author 1.

Ofori et al. 2000 5 • It has been proven that these zero energy homes can lead to saving of energy up to 70% when compared to their traditionally built counterparts. (Parker et al. 2000) Impact of ISO 14000 on construction enterprises in Singapore 4 • DOE defines a Zero Energy Building (ZEB) as a building with greatly reduced energy needs through efficiency gains such that the balance of the energy needs can be supplied by renewable technologies.

Mlecnik et al. 2010 IMPORTANCE OF STUDY • The concept of ZEB needs to be developed within an integrated system approach, not simply as number of discrete, isolated concepts (Wall 1993; Feickert et al. 2009). • Similar to the development of any technology, ZEB can be viewed from the prospective of innovation theory. STEP 2 : Content Analysis STEPS (Robson 2002) : 1. Start with a research question. 2. Decide on sampling strategy. 3. Define the recording unit. 4. Construct categories for analysis. 5. Carry out analysis PARAMETERS IDENTIFIED: 1. Barrier 2. Barrier Breaker 3. Parameter . STEP 4: Gap Analysis Conducted based on: • Mapping (tables) • To identify research gaps and opportunities. • Parameters of each body of literature. .
