controlled in the test cells, causing significant energy waste and potentially unsafe levels of negative pressure. Control of the HVAC equipment in the building had been performed by manually adjusting dampers and heating and cooling set points to satisfy the space requirements and manually turning the equipment off at the end of the working shift. As a result, equipment remained in operation longer than necessary. Because of variations in building occupancy schedules, most HVAC systems ran excessively unless continuously adjusted.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
