Welcome to the BC Comfort Air Conditioning Limited insights newsletter for February 2015. In this edition, we share some insights on saving HVAC energy for Data Centres, along with some important design considerations for saving energy and optimizing your building performance.
We encourage you to visit our blog and LinkedIn Page for more information on improving energy efficiency along with some of our insights on Sustainable Design and Mechanical Systems.
If you would like advice for your next building design project or to learn more about how we can help you to save energy, please contact us today.
Saving HVAC Energy in Data Centres
According to the latest EPA findings, 1.5% of all electricity used in the US is consumed by data centres. Based on historic trends, this number is expected to triple by 2020. For rooms with such tiny footprints, data centres consume a disproportionate amount of energy.
Using an airside economizer can save up to 30% of the total energy usage compared to a traditional HVAC system in a data centre.
An airside economizer is a device that allows outside air to directly cool a space. In the case of a temperate climate like the lower mainland, airside economizers can be used during most periods of the year.
From an energy perspective, 30% of the total energy used by a data centre is used by HVAC cooling, and 8% is used by HVAC fans. By using an airside economizer, the HVAC cooling energy can be reduced significantly.
In contrast, traditional CRAC (computer room air conditioners) use significantly more energy because they cannot take advantage of introducing outside air directly into the space. Instead, air is typically completely recirculated and cooling is achieved through mechanical means using either chilled water or DX refrigeration.
BC Comfort recently completed a large stand alone data centre in North Vancouver with airside economizers. The 17,000 square foot facility primarily uses variable outside air flow and spray-type cooling to maintain free cooling in the building. The facility has 100% redundancy and is built to Tier 3 standards.
If you are interested in learning how your current or future data centre can save a significant amount of energy and cost, please contact BC Comfort at 604-439-3344.

Feature Project:
Recently, our Design Build team started working on a project for Open Road Audi & Volkswagen in Burnaby.
Our team was able to provide significant cost savings to the client by incorporating innovative design ideas for 166,000 Sq.ft of luxury dealership space.
Construction for this project started in February 2015 and is scheduled to be completed by early 2016. More information will be provided in the future.
