The innovative incorporation of enthalpy recovery wheels, variable air volume fume hood controls, envelope improvements, advanced lighting controls, and reduction in lighting power density produced an interactive energy savings of more than 52 percent in cooling and 39 percent in heating, lowering total energy consumption by 35 percent over the standard baseline.
Incorporating the enthalpy wheel generated a payback within the first 12 months of operation. Overall energy reduction after renovations was 60% with an Energy Performance Rating of 89. Trend analysis of proper systems operation has helped uncover opportunities to save additional energy.
The mechanical penthouse – sized for enormous enthalpy or energy-recovery wheels and their air-handling units – is copper clad. The louvered façade of the plenum – which draws in fresh air for the air-handling units – completes the transformation of essential engineering components into an integral element of the dynamic design.
