The baseline building energy consumption is determined based on which guideline?

The baseline building energy consumption is determined based on the Building performance rating method in Appendix G of ASHRAE 90.1:2007. This standard provides a comprehensive framework for calculating the energy performance of buildings, allowing for the establishment of a baseline against which the energy usage of a proposed building can be measured.

ASHRAE 90.1:2007 is pivotal as it includes specific methodologies for determining energy efficiency criteria and benchmarks, which are essential for architects and builders aiming for sustainable design. The use of this guideline ensures that the baseline energy consumption is calculated in a consistent and standardized manner, providing a reliable foundation for evaluating improvements in energy use and promoting more energy-efficient building designs.

The other options, while potentially relevant in different contexts, do not serve as primary guidelines for establishing baseline energy consumption within the framework of Estidama or the specific requirements set forth in the Pearl Building Rating System. Therefore, relying on recognized standards like ASHRAE ensures robust, data-driven assessments aligned with best practices in energy efficiency.
