Energy Efficient Supertall
The 71 storey Pearl River Tower incorporates wind turbines, a double skin façade, radiant cooling, underfloor air distribution, and solar photovoltaics.
-
Services
- Climate conditions
- Helped design façades using RWDI-Skin and CFD
- Proved performance of ventilation systems
- Radiant cooling
- Structural loading
- Cladding loading and pressures
- Wind comfort
- Urban wind energy
- Stack effect
-
Benefits
- Configuration of double skin façade established
- Glass selection justified
- Optimal cavity airflow rates determined
- The need for seals on the interior glazing of the double skin façade confirmed
- The benefits of automated blinds determined
- Determined need for light-weight radiant panels and/or chilled beams, rather than high thermal mass type cooling
- Magnitude of infiltration of moisture into the building during off hours and the timeframe of HVAC system restart and surface temperature control of radiant panels was estimated to minimize risks of condensation.
- Underfloor Air Distribution (UFAD) diffuser performance evaluated
- Wind energy potential assessed and design fine-tuned
- Accurate wind loads on the structure and cladding, to help minimize material costs, determined
- Prediction of satisfactory pedestrian comfort around base of tower provided confidence that the building and landscape design will achieve intended uses
