Purpose and Background
These presentations were recorded at the AEI 2025 Conference.
Parametric Analysis of Low-E Coating’s Impact on Double Glazing Windows (26 minutes)
This presentation explores the energy efficiency potential and thermal performance challenges of Low-Emissivity (Low-E) coatings on double-glazed windows. Through parametric analysis using EnergyPlus software and EMS scripting, the presenter investigates how surface placement of Low-E coatings affects building energy consumption and condensation risk, especially in cold climates. The study analyzes three window systems: clear glazing, exterior-coated Low-E, and interior-coated Low-E configurations. Simulation results show significant energy savings with Low-E coatings, up to 70.6% in certain zones, but also reveal increased risk of condensation, particularly on colder window surfaces. The findings emphasize the importance of considering condensation effects in both new design and retrofit scenarios. This research offers insights into optimizing Low-E coating placement for enhanced energy performance while minimizing adverse side effects.
World's First and Tallest Multi-Story Engineered Mass Bamboo Building (33 minutes)
This presentation highlights the development, design, and testing of the world’s tallest engineered mass bamboo building, a seven-story structure located in China. The presenter details the creation and structural performance of GluBam, a sustainable glued-laminated bamboo product engineered for high strength and low carbon emissions. The presentation covers design methodologies, lateral resistance systems, prefabrication techniques, and structural testing including torsion, vibration, and dynamic load response. The project emphasizes the potential of bamboo as a renewable alternative to traditional materials like steel and concrete, offering comparable mechanical properties and reduced environmental impact. The building serves as a real-world testbed for ongoing research in material behavior, fire resistance, and digital twin modeling.
Dorothy Height Elementary School: Reimagining A Historic Campus for A More Sustainable Future (14 minutes)
This presentation details the sustainable transformation of Dorothy Height Elementary School in Washington, D.C., a historic campus modernized to meet LEED Gold, WELL, and near net-zero energy performance targets. The design team addressed challenges including limited site space, historic preservation constraints, and pandemic-related supply issues. Innovative MEP strategies included geothermal ground source heat pumps, demand-controlled ventilation with sorbent filtration, water-source heat pumps for domestic water, and full electrification. Creative structural solutions allow integration of new systems within old spaces, while advanced metering and daylighting enhanced operational efficiency. The project remains a model for retrofitting legacy buildings to meet modern energy codes and sustainability standards.
