Abstract: This study developed essential parameters to be employed as tools for supporting decisions regarding the implementation of green technologies (GT) in buildings. This was done by identifying the most significant parameters that affect the performance of GT in buildings, primarily from the perspective of facility managers as well as the present and future facility users, public and the environment. They include cost, user needs, simplicity, integration and availability of service and maintenance. These parameters were further mapped into measurable equivalents that may prove useful in the development of a model for performance indexing of GT. The developed model may further be used to predict the resulting grades or |shades of green technologies| (SGT). The specific objective of the present paper is to present the most important benefits to people and the environment following the application of GT. One may argue that not only |green| but any building technology should satisfy some basic qualitative and quantitative criteria in order to be considered viable for a building construction project. The phrase |shades of green technologies| is offered here to reflect the potential for |scaling| or grading of |green| in building construction projects.
