Abstract

In order to achieve energy savings in existing buildings, there is an increasing need for energy audits and performance checks. In this regard, estimating a building's U-value is crucial, and there are a variety of methods available for achieving this. Heat flow meters can be used to measure U-value in situ. This dataset reports on an experimental campaign that evaluated the insulation and performance of the fabric elements of a building located in Dublin, Ireland. The experimental study conducted on the "Block F" building provided insights into the building's thermal performance by measuring the U-value of various windows and walls across different locations and floors. The average heat loss coefficient for windows was approximately 1.74 W/(m²K) before data cleaning and 1.99 W/(m²K) after cleaning, while walls had an average of 0.90 W/(m²K) before cleaning and 1.07 W/(m²K) after cleaning. The findings demonstrated that similar types of windows and walls components gave significantly different U-values.
