Final answer:
To measure attached properties with common walls according to the RMS standard, it is important to consider the U-values and R-values of the walls and windows. These values represent the heat loss properties and insulation of the materials and components, providing insight into the energy efficiency of the properties.
Step-by-step explanation:
In order to measure attached properties with common walls according to the Root Mean Square (RMS) standard, it is important to consider the U-values and R-values of the walls and windows. The U-value represents the heat loss properties of a material or component, where lower values indicate better insulation. On the other hand, the R-value is an inverse measure of the U-value, with higher values representing better insulation.
For example, a Passive House wall with a U-value of 0.15 W/m²/°C would have an impressive R-value of approximately 38. Similarly, windows with a U-value of 0.8 W/m²/°C would have an R-value of around 7. These values are important in determining the heat flow and energy efficiency of the property.
By measuring the U-values and R-values of the common walls and windows, the RMS standard enables accurate assessment of the heat loss properties and energy efficiency of attached properties.
