Solar shading as a seasonal control system in the facade, for hot-humid Gulf Coast climates: interior and exterior devices compared, daylighting tradeoffs, automation and controls, and how exterior venetian blinds behave under wind loads.
A Passive House home in Fort Collins, Colorado, built on an existing foundation to cut embodied carbon. The owner-builders, architect, and consultant on the design, designPH modeling, certification choices, and lessons learned.
Passive House performance in cold climates with natural materials such as cellulose, wood fiber, hemp, straw, and earth: airtightness and superinsulation first, thermal mass as a tuning layer, and vapor-open assemblies detailed for moisture control.
Bauen Build and Shape Architecture Studio on the Flatiron House, where the Passive House consultant and the mechanical and structural engineers worked together from the start, for a smooth pre-certification and cost-effective, ultra-low-energy design.
Ventilation design for the Midwest's long, dry winters and hot, humid summers, using Zehnder as a case study: balanced ERVs, airflow balancing, sizing and controls, dehumidification, and filtration for smoke events.
Structural insulated panels as a path to Passive House performance, shown through projects from Maryland to British Columbia: airtightness, thermal continuity, moisture management, and the detailing, testing, and commissioning behind them.
How the Passive House approach adapts to new construction types, steel included, with Bethany Senior Terraces, affordable housing and the first Passive House modular multifamily building in New York City, as the case study.
Air-to-water heat pumps and hydronic distribution in place of ductwork and indoor refrigerant lines: what changes for architects, builders, and owners in space, installation, indoor air quality, and code compliance.
Building and construction is the second-largest user of plastics after packaging. Their impacts on health and the environment across the life cycle, and how the industry can move to healthier, more resilient alternatives.
A PHI-accredited certifier compares designPH, easyPH, and PHPP side by side: what each tool can reliably tell you, when to move from early design tools into PHPP, and how both tools support PHPP rather than replace it.
