Final answer:
Buildings with basements, cellars, or crawl spaces or floors below grade should be provided with additional insulation, waterproofing measures, and ventilation.
Step-by-step explanation:
Buildings with basements, cellars, or crawl spaces or floors below grade should be provided with additional insulation, waterproofing measures, and ventilation.
Extra insulation helps to prevent heat loss and maintain a comfortable temperature inside the building.
Waterproofing measures are necessary to protect the building from water damage and prevent moisture from entering below grade areas.
Proper ventilation is important for maintaining air quality and preventing the accumulation of harmful gases, such as radon, in basements.
