Subtask B "Solutions" investigated the cooling performance of existing mechanical, natural and hybrid ventilation systems and technologies and typical comfort control solutions as a starting point for extending the boundaries for their use. Based upon these investigations the subtask also developed recommendations for new kinds of flexible and ...
A smart ventilation system adjusts ventilation rates in time or by location in a building to be responsive to one or more of the following: occupancy, outdoor thermal and air quality conditions, electricity grid needs, direct sensing of contaminants, operation of other air moving and air cleaning systems.
The main types of shed construction are metal sheathing over a metal frame, plastic sheathing and frame, all-wood construction (the roof may be asphalt shingled or sheathed in tin), and vinyl-sided sheds built over a wooden frame. Small sheds may include a wooden or plastic floor, while more permanent ones may be built on a concrete pad or ...
When you only need to store a few things, a small shed like this is so helpful. It’s large enough to store rakes, shovels, and garden tools, and it won’t take up too much space in your yard ...
Constant air volume (CAV) is a type of heating, ventilating, and air-conditioning system. In a simple CAV system, the supply air flow rate is constant, but the supply air temperature is varied to meet the thermal loads of a space. [1] Most CAV systems are small, and serve a single thermal zone.
UFAD can bring several potential advantages over traditional overhead systems, including reduced life-cycle building costs; improved thermal comfort, occupant satisfaction, and productivity; improved ventilation efficiency, indoor air quality, and health; reduced energy use and static pressures; and reduced floor-to-floor height in new ...
Within these principles, projects must pass building specified blower door, ventilation airflow, overall airflow, and electrical load tests; buildings must also achieve other measures such as low-emission materials, renewable energy systems, moisture control, outdoor ventilation, energy efficient ventilation and space conditioning equipment.
