Environmental Loads and Design Procedures |
| 5.2.1.1. |
Exterior Environmental Loads
- Above ground climatic loads shall be determined according to Subsection 1.1.3.
- Except as provided in Sentence (3), below ground exterior environmental loads not described in Subsection 1.1.3. shall be determined from existing geological and hydrological data or from site tests.
- Where local design and construction practice has shown soil temperature analysis to be unnecessary, soil temperatures need not be determined.
(See Note A-5.2.1.1.(3).)
|
| 5.2.1.2. |
Interior Environmental Loads
- Interior environmental loads shall be determined in accordance with good practice as described in Sentence 6.2.1.1.(1) based on the intended use of the space. (See Note A-5.2.1.2.(1).)
|
| 5.2.1.3. |
Environmental Load and Transfer Calculations
- Calculations related to the transfer of heat, air and moisture and the transmission of sound shall conform to good practice such as that described in the ASHRAE Handbooks.
- For the purposes of any analysis conducted to indicate conformance to the thermal resistance levels required in Article 5.3.1.2., soil temperatures shall be determined based on annual average soil temperature, seasonal amplitude of variation and attenuation of variation with depth.
- Wind load calculations shall conform to Subsection 4.1.7.
