83. Radiant thermal comfort
To maximize floor space, reduce dust transmission and increase thermal comfort by incorporating radiant heat and cooling systems into the building design.
New technology surrounding radiant temperature systems has led to recent advances making the systems more energy efficient. Additional benefits include saved floor space, lower dust transportation and increased thermal comfort through the separation of temperature controls and outdoor air supply systems. In addition, with the use of radiant heating, the mean radiant temperature in a space can be kept lower compared to convective heating, providing the benefit of a slightly higher relative humidity in winter time.
All lobbies and other common spaces meet the requirements set forth in ASHRAE Standard 55-2013 for thermal comfort through the use of one of the following systems:
At least 50% of the floor area in all offices and other regularly occupied spaces meets the requirements set forth in ASHRAE Standard 55-2013 for thermal comfort through the use of one of the following systems:
