M04: Internal Walls

Intention

To select an internal wall specification with a lower embodied energy than the typical specification. The internal wall specifications matching the actual building design must be entered in the software in all cases.

Approach/Methodologies

The design team must select the specification from the drop-down list that most closely resembles the internal walls specified, and enter the thickness, which is a requirement of EDGE. Where there are multiple specifications the predominant specification must be selected.

Potential Technologies/Strategies

The following is a list of the specifications included in EDGE. Only the broad wall types are described here; EDGE does not include options on plaster or finishing. The user must always try to select the specification that most closely resembles that of the building design.

Relationship to Other Measures

The specification of internal walls does not affect other EDGE measures but can impact acoustic performance.

Assumptions

The base case assumption is that internal walls are constructed from 200mm common brick plastered on both sides.

Compliance Guidance

Design Stage	Post-Construction Stage
At the design stage, the following must be used to demonstrate compliance:  Drawings of the internal wall sections; or Manufacturer’s data sheet for building materials used for internal wall specifications if available; or  Bill of quantities with the materials used for the internal wall clearly highlighted.	At the post-construction stage, the following must be used to demonstrate compliance:  Date stamped photograph of the wall taken during or after construction; and  Purchase receipt for the building materials used for wall construction; or  Delivery note for materials used for wall construction.
