Interview Questions for Green Globes

Green Globes is a comprehensive green building rating system that assesses the environmental performance of buildings and their operations. Unlike LEED, which uses a points-based system, Green Globes employs a rating scale based on a percentage of compliance with its criteria. This means that Green Globes focuses on a holistic assessment, evaluating building attributes across various categories and providing a percentage score indicating the overall sustainability performance. LEED, on the other hand, awards points based on specific achievements and then translates those points into a certification level (Certified, Silver, Gold, Platinum). This fundamental difference leads to contrasting approaches: Green Globes provides a more continuous assessment of performance improvement, while LEED provides a more categorical certification achievement. Another key difference lies in their scope; LEED often focuses more on new construction while Green Globes includes existing buildings, interiors, and even entire communities. For example, achieving 80% in Green Globes might reflect comprehensive improvements in energy efficiency, water conservation, and waste management, while a LEED Silver certification might represent specific high-performing features with trade-offs in other areas.

I have extensive experience conducting Green Globes assessments across diverse building typologies, including office buildings, healthcare facilities, schools, and even mixed-use developments. My work involves on-site inspections, reviewing documentation, interviewing building occupants and managers, and using the online Green Globes rating system to track progress. For example, I recently conducted an assessment for a large office building aiming to improve its energy performance. This involved analyzing energy consumption data, evaluating the building’s HVAC system, and identifying opportunities for lighting upgrades. The process not only involved quantitative data analysis but also qualitative observations, such as assessing occupant behavior and identifying areas of waste generation. Another memorable project was assessing a school seeking LEED and Green Globes certifications concurrently. The parallel assessments allowed us to highlight both the differences and similarities in the two rating systems and their approaches to achieving sustainability goals.

Achieving a high Green Globes rating requires a multifaceted approach that addresses several key areas. These include:

• Energy Efficiency: Minimizing energy consumption through efficient building design, HVAC systems, lighting, and renewable energy sources. This might involve strategies such as using high-performance windows, optimizing HVAC controls, and integrating solar panels.
