U-value and Your Requirements
Why U-values matter
Using building components with low U-values (i.e. good) has a number of advantages:
- It saves money
- It’s good for your health
- It gives better indoor thermal comfort
A house built with low U-value building components will use less energy and the building owner saves money on their energy bills.
Good U-value building components increase the surface temperature on the inside which is critical in preventing surface mould growth.
Good U-values also improve the indoor thermal climate and create healthy buildings for their residents.
The U-value of a building element (i.e Walls, Floors or Roofs) is a measure of the thermal efficiency or heat loss through that element.The lower the U-value the better the thermeal efficiency of the element.
For new dwellings the elemential U-value is outlinned in the table below.
