Ferrer Garcia, Eduardo R (2014-08). Comparison of the Perception of Facility Managers on Green Roofs Attributes and Barriers to their Implementation. Master's Thesis.
This study compares perceptions of facility managers on green roof attributes and barriers for their implementation. The population under study were the four IFMA chapters of the State of Texas (Austin, Dallas-Fort-Worth, Houston and San Antonio). A questionnaire containing 21 statements related to green roof attributes and 14 statements related to green roof barriers for their implementation was used and responses were measured on a five-point Likert scale. Two types of questionnaires were used to collect responses. An online questionnaire that was distributed through the chapter's members list, and face to face responses were obtained on IFMA chapters meetings. The response rate for the questionnaire was 7.7%. The nonparametric statistic method of Kruskal-Wallis was used to check for differences among the four chapters with respect to perceptions on a given statement. The responses suggest that facility managers generally agreed with the majority of the statements regarding benefits that green roofs can provide. Similarly, the majority of facility managers tended to agree with the statements regarding barriers for green roofs implementation. The results of the investigation for ?=0.05 and a p-value=7.815 showed that no significant differences were found for any of the 35 statements with respect to the facility managers perceptions.
