Increased fresh air supply may double energy costs when operating a conventional HVAC system. This article proposes an alternative HVAC solution which couples novel radiant systems with natural ventilation.
We estimate this solution would address thermal comfort needs in all major climate zones. Where adopted, this solution could reduce building HVAC energy demand by 10–45%.
Join Mark Gardner, William Braham, and Achilles Kallergis for a conversation about the Ger for the 21st century that will focus on William’s work with the Center for Environmental Building + Design (CEBD) at the University of Pennsylvania he has been developing for the last 4 years. That project grew into a collaboration with UNICEF, Arc’teryx, North Face, and KieranTimberlake Architects to test new construction assemblies and evaluate the thermal behavior of ger over time.

Floating structures for urban waterfronts are a potential adaptation strategy to sea-level rise, but how do you provide energy and water to these off-grid buildings? For the past year we have been working with on energy and water self-sufficiency strategies for waterfront buildings.

In this piece, architects Ahu Aydogan and Dorit Aviv along with the architectural historians Daniel A. Barber and PLATFORM’s Marta Gutman discuss air quality during the pandemic. Daniel, a historian of architectural environmentalism, convened this discussion inviting Ahu and Dorit, designers and researchers specializing in the fields of energy and ecology, and Marta, an historian of children’s spaces, to the “table.”

Instruments measuring the outdoor radiant environment are limited spatially. They aggregate observations to singular points, eliminating variations from surrounding surface temperatures. Computational methods can characterize the heterogeneous outdoor radiant environment, but spatial validation with accurate tools remains difficult. We use two novel sensing platforms (MaRTy and SMaRT) and an innovative computational validation method to explore Mean Radiant Temperature (MRT) spatial variation outdoors.
Diagram of Philadelphia region illustrating the benefit received by two different locations, an exurban center, Norristown CBD, and a rural township, Bass River, NJ. Each receives some benefit from each of the other 1,378 census tracts, but the UME of Norristown is double its EAB, while that of Bass River is reduced to 70%.

A roof aperture lined with hydrogel membrane is proposed for combined evaporative and radiative cooling in the desert climate. Digital simulation tools of CFD, solar radiation, and radiant sky cooling analysis, were employed to analyze the overall geometry and material impact on airflow and radiant heat exchange.

In order to make the embodied effect of radiant surfaces' geometry legible, we have developed a Mean Radiant Temperature simulation tool which is based on a raytracing technique and accounts for the detailed geometry of the human body and its surrounding environment.
