Li Ka Shing Knowledge Institute variable air volume retrofit
The variable air volume machine in Li Ka Shing Knowledge Institute.
Date: August 31, 2016
Details: The constant air volume HVAC system was replaced with a variable air volume system for the Li Ka Shing Knowledge Institute.
The constant air volume systems supply air at a single temperature and a constant volume. Variable air volume systems are a more energy efficient option because the fan’s speed adjusts to fit the temperature requirements needed in a given space. The new systems enable more precise temperature control and lower energy consumption.
Greening impact for both pumps:
- Energy saved – 2,246,416 kWh since 2015
- Incentive received from SaveONenergy.
Graph showing the amount of energy per year saved from switching to a variable air volume system. St. Michael’s Hospital has saved about 25 per cent of the energy once used to power the constant air volume system.
