Part L 2011, Fabric Performance and towards Nearly Zero Energy Buildings (NZEB) and Zero Carbon House standards

Xtratherm Logo 285

Organisation profile

Xtratherm is an Irish manufacturer committed to supporting the construction industry in the delivery of Low and Zero Carbon buildings.

From design stage to the delivery of ‘A’ rated buildings, the construction professional can rely on the expertise and support of the Xtratherm team. It is through the interaction between manufacturers, designers, engineers, builders and energy assessors that together we can formulate strategies to ‘Close the Gap’ between design and actual performance on site.

Training aim

The course aims to introduce BER assessors and designers to the targets to meet in terms of U-value, thermal bridging and air permeability to achieve compliance with Part L2011.

Learning objectives

Part L 2011 targets for all elements of the fabric.
– Specifications to aim for to achieve Part L 2011 compliance and an A3 BER.
– What is the thermal bridging factor, the Y-value, and its calculation from Part L 2011 documentation.
– The importance of “Fabric First” approach (U-value,Y-value, permeability) to comply with Part L 2011 efficiently.
– Upcoming changes on Part L to meet Zero Carbon House and Near Zero Energy Buildings performance

– Validation process on on site to comply with BCAR.

Course outline

After introducing the stated goals of Part L 2011, we will go through each of the elements of the fabric and their corresponding specification to achieve compliance in terms of U-value. We will also introduce how to meet the thermal bridging (Y-value) and air permeability targets, and their relative influence on the design cost. Finally, we will look at the coming Zero Carbon House and Nearly Zero Energy Buildings targets in the next revision of Part L and the associated changes to expect.
