The share of production primary energy use of the improved building alternatives was 39 54% of the total primary energy use for production, space heating, space cooling and ventilation over 50-year lifespan, compared to 31 42% for the initial alternatives.
The primary energy for material production constitutes 5% of the primary energy for production and space heating and ventilation of an electric heated building built to meet the 1994 code.
The SADCS mainly consisted of desiccant wheel, thermal wheel, evaporative coolers, solar air collectors and gas-fired auxiliary heater, it could directly tackle both the space load and ventilation load.
These results demonstrate the need for on-going efforts to ensure sufficient floor space and adequate ventilation in DCCs to maintain good IAQ.
Specific lamps emitting only UVA1 radiation are usually expensive and require specific cabins with unique space and dedicated ventilation machinery.
Insufflation of gas at higher flows (up to 8 1/min) has been demonstrated to reduce the amount of dead space and minute ventilation, while improving arterial PCO2 [ 3, 4].
Some additional considerations include the concentration of infectious droplets determined by the volume of the space and its ventilation, the length of time of exposure, as well as the status of defense mechanisms of the exposed individual.
It is important to additionally consider the concentration of infectious particles determined by the volume of the space and its ventilation, the length of time of exposure, as well as the status of defense mechanisms of the exposed individual.
Inflated, normal, poorly aerated or nonaerated airway spaces coexist, and ventilation may induce (1) shear stress at the boundaries of these spaces, (2) inadequate cyclic opening and (3) closing of alveoli.
