LEED-AP-BD+C Exam Dumps : LEED AP Building Design + Construction (LEED AP BD+C)

The correct answer is D. critically reviewed life-cycle assessment conforming to ISO 14044. This is because:

•Option 1 of this credit requires the use of products that have environmental product declarations (EPDs), which are documents that provide information about the environmental impact of a product throughout its life cycle1.

•EPDs are based on life-cycle assessments (LCAs), which are systematic analyses of the environmental aspects and potential impacts of a product from raw material extraction to disposal2.

•LCAs must conform to the international standard ISO 14044, which specifies the principles and framework for conducting and reporting LCAs3. LCAs must also be critically reviewed by an independent panel of experts to ensure their validity and reliability4.

•The other options are not relevant for this credit. FSC certification is a label that indicates that a wood product comes from a well-managed forest5. Cradle-to-cradle certification is a label that indicates that a product is designed for circular economy, with minimal waste and toxicity. CSR is a report that discloses the social and environmental performance of a company.

Conducting a site analysis is a method to assess the regional context of a building’s design for sustainability. A site analysis involves collecting and evaluating information about the site’s location, climate, ecology, history, culture, infrastructure, regulations, and stakeholders. This can help identify the opportunities and constraints for the project, as well as the potential impacts and benefits for the environment and the community. A site analysis can inform the design decisions regarding site selection, site development, water management, energy efficiency, material selection, indoor environmental quality, and innovation12.

Using economizer strategies (A) can offset the additional energy required to increase ventilation. Economizers allow the HVAC system to bring in cooler outdoor air when conditions permit, thus reducing mechanical cooling needs. This method aligns with LEED’s goals for energy efficiency while maintaining indoor air quality. High MERV filters (B) may increase energy usage due to airflow resistance, and reducing duct size (D) can limit airflow efficiency, counteracting ventilation improvements.
