The Green Grid defines the PUE and DCiE calculations as:
PUE = Total Facility Power / IT Equipment Power
DCiE = IT Equipment Power/Total Facility Power x 100%
As an example, a data centre with a PUE of 2 indicates the energy demand is
two times greater than the energy required to power the IT equipment.
Changes in the environment and increasing publicity of data centre energy usage
has resulted in demand for efficient data centres. Consistently, the number of
data centres obtaining LEED certification increases each year, representing the
acceptance of the program and the dedication from data centre professionals
to create facilities with less environmental impact.

CRSC Green Data Centre Commitment
CRSC has made a corporate commitment to reduce energy consumption in data
centres. Our strategy is to minimize environmental impact and increase data centre
operating efficiencies. Our method of design, build and maintenance consists of:
• Researching alternative construction methods
• Determining efficient cooling options
• Reducing energy consumption by utilizing high efficiency equipment such
as UPS systems and transformers
• Use of products with low Volatile Organic Compounds (VOCs)
• Utilizing local products and resources to reduce CO2 emissions associated with
• Determining potential for server virtualization
• Recycling old equipment
• Utilizing Computational Fluid Dynamics to determine temperature, airflow,
pressure, and relative humidity
• Performing infrared thermography imaging to determine heat production and
performance issues from corroding electrical components
• Proper cleaning and maintenance of the data centre and the equipment
• Continuously monitoring the data centre to ensure the equipment is operating
properly, to recognize potential issues, and evaluate the overall efficiency
Did you know?
With the intense demand data centres place on the power grid, many power suppliers have launched incentive programs to encourage
companies to improve their energy efficiencies. These incentives can offer up to $300 per kilowatt of savings to a maximum of 50% of
the retrofit expense. Contact your power distributor to find out if there is an incentive program in your area.
With extensive experience in data centres, CRSC has developed an Energy Efficiency Audit to assess the energy consumption within
the data centre to determine areas where the efficiency can be improved – including server virtualization, air distribution methodologies,
high efficiency cooling, and power equipment that is right-sized to the load. Implementing the recommendations may contribute to a
power supplier incentive program, therefore resulting in energy savings and a financial return on investment.
