Section 6 Analysis and Results

This dialogue allows you to perform various types of Section 6 analysis and view the results. It is accessed via the ‘Building Regs’ button near the lower edge of the <VE> Compliance view.

This tab allows you to specify and carry out the Section 6 analysis. It also provides a route to the Building & System Data dialogue. 

Accesses the Building & System Data (see Section 2).

This part of the dialogue covers analysis for buildings of type ‘Dwelling’. Tick the methods by which you wish to analyse the design.

Tick this box to analyse by the Elemental Method.

Tick this box to analyse by the Target U-value Method.

Tick this box to analyse by the Carbon Index Method.

This part of the dialogue covers the analysis of non-dwellings. Tick the methods by which you wish to analyse the design.

Tick this box to analyse by the Elemental Method and the Heat Loss Method (together with the associated building services checks).

Tick this box to include the Office CPI Method in the L2 Elemental or Heat Loss analysis. This option is only available if the building type is Office.

Tick this box to analyse by certain components of the Carbon Emissions Method. The analysis covers the Table J8.8 U-value requirement, issues relating to heat bridging and air infiltration (sections J9 & J10) and building services commissioning requirements (section J14). The comparison of carbon emissions must be performed separately by simulation or other suitable means.

This tab displays the results of the Section 6 analysis.

The results displayed will depend on the type of analysis conducted.

The Overall result of the Part L analysis indicates whether the building has passed or failed.

Results for each Method are also displayed, as follows:

For dwellings:

Elemental Method, Target U-value Method, Carbon Index (SAP) Method.

For non-dwellings:

Elemental Method, Whole-building Method, Carbon Emissions Calculation Method.

Click this button to display the detailed results file. This is an HTML file setting out the Section 6 analysis in the form of a worksheet. All Section 6 results files are stored in the ‘regs\PartJ’ sub-folder of the project folder.

In the case of the Carbon Index Method for dwellings, the worksheet is presented in a format very similar to that appearing in SAP 2001^[3]. Intermediate calculations are set out where this helps to clarify the analysis. In a few places the text accompanying the SAP 2001 worksheet has been extended to indicate variants of the calculation methods described in the body of the document but omitted from the worksheet. In these places the additional text is shown in a reduced-size font. For example, the title for section 12 appears as ‘Carbon Index (CI) for individual and community heating without CHP or heat recovered from power stations’.
