Virtual Architectural EnergeticsVirtual architectural reconstruction processes and products can be applied to analytical methodologies such as architectural energetics to address questions about: labor costs diachronic labor control “communities of [architectural] practice”

nearly 100k person-days to construct the Xunantunich Palace

correlation of construction phases site-wide

exploring labor populations internally and through a technological lens

Continuing to strengthen virtual/digital pursuits as internally effective research assets, alongside the more visually compelling applications for presentation and public engagement.
