Saving Energy While Improving Comfort and Productivity In actuality, well-designed, naturally-ventilated buildings lead to profitability in many ways. They have the potential to cut energy use of air-conditioned buildings in half . Access to fresh air also results in better employee outputs. Natural ventilation can increase productivity by up to 11 percent , showing that the profitability of a building’s design can be tied directly to the workforce inside. There’s also the satisfaction derived from self-assessed productivity and the perception of control according to Adrian Leaman and Bill Boardass, as well as a deeper connection to the outdoors . In addition to a sense of well-being, employees in naturally-ventilated buildings are …show more content…

Studies have shown that these kinds of devices can save on annual energy costs by 40 percent . 2. Powered Window Actuators: We have them in cars, so why not in buildings? Taking measurements of various conditions inside and outside a building, such as wind speed, dust particulate volume, and temperature levels, sensors can be programmed to open vents automatically at various positions to suit specific conditions. These devices are cost effective, as a single sensor can control a number of vents. Window actuators allow a machine-based approach to open windows when conditions are ideal or when the building’s design prevents human access to hard-to-reach vents. By introducing a simple device with a programmed algorithm, the efficiency of the HVAC system can be instantly improved. 3. Monsoon Windows: For office buildings in the tropics, windows have to be closed when it rains heavily, which results in shutting off airflow. With monsoon windows , a rain sensor closes windows when it rains, however there is still airflow into the interior. 4. Full fresh air mode: just like with cars where one can turn off the AC and have the fan on outside air mode left on, the mechanical systems in offices can be designed to have a ‘full fresh air’ mode. The windows can of course be left open to flush out internal heat gains and humidity. 5. Night Ventilation Cooling: In the sub-tropics, where the outdoor temperature in the evening is generally lower, night ventilation
