An 8,000 m2 building at a BC based tertiary education institute was looking to extend the lifetime of the facility while reducing greenhouse gas emissions. With old mechanical systems and lighting reaching the end of their life, there were extensive opportunities for energy efficient retrofits of the building.
Michael Pullinger completed an energy model which assessed major refurbishment and electrification options, including LED lighting, replacement of the existing heating system with heat pumps, and building envelope modifications. Together these have the potential to eliminate almost half the total energy consumption and almost all greenhouse gas emissions.
A proposed 25 MW run-of-river hydroelectric project needed to understand the effectiveness of the scouring effect through their sluice channel.
Michael Pullinger prepared a multi-phase CFD model to predict shear forces along the bed of the sluice channel to predict how effectively the sluice gates prevent sediment buildup.
A small selection of additional modelling projects that Michael has been involved with include:
- Whole building energy model of a 40,000 m2 luxury hotel building to assess the effectiveness of a variable speed pumping retrofit at a BC ski resort.
- Preparation of an energy model to optimise the configuration of a hybrid renewable energy micro-grid in a thirty residence off-grid community with solar, hydro, battery and diesel generation.
- Computational fluid dynamics (CFD) optimisation of the intake configuration for a 77 MW run-of-river intake and headpond.
- Exterior wind environment modelling using CFD for pedestrian comfort in the vicinity of a new multi-purpose arts theatre and entertainment building.
- Compliance modelling for a 48 storey, 70,000 m2 building for 5 star NABERS office energy efficiency rating.
- Hydraulic transient (waterhammer) analysis for a 1334 MW pumped-storage hydroelectric system with 4x reversible Francis pump-turbines.
