How do you determine which approaches and technologies will meet your needs and give you the best return on your investment? The information here is intended to assist you in identifying the best solutions for your building or application.
The best way to cut energy consumption significantly is with systems that meet YOUR building's energy loads. Although every building, lifestyle, or process is unique, building science and economics emphasize ordinarily following these guidelines. For commercial buildings or a unique house plan, use HOT-2000 and RETScreen or contact us to determine the systems that deliver the optimum return to your investment.
Renovating an Existing Building
In Canada, the first step to improving energy performance of buildings is to upgrade the envelope. A leaky, energy guzzling building must be upgraded before Renewable Energy Systems can have any impact. Exceptions include process manufacturing and larger buildings. See Energy Efficiency and Projects.

After upgrading your building envelope, what are your energy needs?
Taking it Further
Solar Power (PV) is usually the last consideration for most buildings from an economic point of view, except for remote locations and for blackout protection where it can be a #1 consideration. Examples include:
Building New or a Major Addition
Passive Solar Design is the most effective and efficient way to cut energy load. Explore free lighting, cooling and ventilation techniques whenever possible, i.e., Whenever Building!
