It doesn't take a rocket scientist to figure out that buildings in different geographies consume energy differently. We all know that everything from sunlight, the wind, ambient temperature, air quality, humidity and time of sunrise/sunset to the topography of a commercial building invariably affect how we use HVAC and Lighting. In other words, the location and environment of your building determine the way your building consumes energy.
And yet, there is a good chance that you have overlooked the importance of geography when planning for energy efficiency.
