Köppen climate types of Virginia, using 1991-2020 climate normals Due to the elevation, the Blue Ridge Mountains have a humid continental climate.. The climate of Virginia, a state on the east coast of the United States, is mild compared to more northern areas of the United States such as New England and the Midwest.
Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value (in K⋅m 2 /W) is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction. [3]
All thermal insulation requirements in ASHRAE 90.1 are divided by the climate zone, it means that the amount of insulation needed for a building is determined by which climate zone the building locates. The thermal insulation requirements are shown as R-value and continuous insulation R-value as the second index. [13]
The climate of Virginia varies according to location, and becomes increasingly warmer and humid farther south and east. [19] Most of the state has a humid subtropical climate, from the Blue Ridge Mountains and southern Shenandoah Valley to the Atlantic coast. In the Blue Ridge Mountains, the climate becomes subtropical highland. [citation needed]
[7] [22] In the 2021 IECC model code, for example, there are provisions that reference ASHRAE 90.1 concerning insulation R-values for opaque parts of the building envelope. [22] As another example, there are provisions in the IECC concerning the length, flow-rate, and insulation of piping as it relates to hot-water heaters in commercial ...
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.

The World Urban Database and Access Portal Tools (WUDAPT) is a global initiative of tools to create local climate zone maps for a given city using a standard methodology. [1] It has both a database and a portal. The database has hierarchical layers of increasing detail, with data acquired via crowdsourcing methods such as Geo-Wiki. [2]
