If natural ventilation strategies are integrated into the design, ensure that key elements of the natural ventilation system, such as operable windows, window actuators, controls, operable atrium elements, and solar chimneys, are not compromised during value engineering. Educate decision-makers about the natural ventilation design and the importance of maintaining all the key components. If these elements are altered in a way that compromises natural ventilation rates, the mechanical system may no longer be sized appropriately.
For mechanically ventilated spaces, run ventilation calculations to verify that the final design meets the minimum outside air rates equal to or exceeding the ASHRAE 62.1-2007 minimum.
The landscape architect runs final outdoor water use calculations for the project’s design case annual water usage. These calculations should confirm that the landscape water reduction goals are met. If the goals are not met, adjust the landscape and irrigation design as needed.
Include details on preparation, protection and any special arrangement required during construction. Reused elements may need protective coverings and sheets from contaminants and construction dust
