How can Elmhurst help you?

• Getting a head start on changes to regulations is very

important from a technical and financial view.

• The changes could affect dwelling types differently.

This could result in different specifications for flats, houses etc.

• Elmhurst recognised this so in the new year started

work on development of software to enable house builders to assess the changes to Section 6.

How can Elmhurst help you?

• Elmhurst has listened to user feedback from

previous versions of software when developing Design SAP 2012.

• Elmhurst aim to make Design SAP 2012 the

most comprehensive but user friendly SAP software package.

• User feedback collected and has resulted in

improvements to reports, interface, manuals, data entry etc.

How can Elmhurst help you?

• Design SAP 2012 software was approved for Section 6 2015
• n 2nd April 2015.
• Design SAP 2012 allows modelling of dwelling types in

anticipation of Section 6 2015 introduction.

• Results displayed in real time and allow users to start to

develop strategies to enable compliance;

How can Elmhurst help you?

• House types modelled against Section 6 2010 can

be automatically updated to Section 6 2015.

• For a free, 30 day demo of Design SAP 2012

Handouts

By working in conjunction with CSILG and HFS, a range of pre-calculated solutions will be presented to provide the attendees with an appreciation of the new performance requirements. In addition the following wall chart will be pre- printed in large format and co-branded with supporting partner logos etc.

Part 2 SAP Workshop

Step 1: Opportunities and Risks

• 5 top risks and / or opportunities

industry faces to delivering the new 2015 building standards.

• Think across the entire new build

process / supply chain.

• Populate the top half of the chart

with post –its in appropriate column

• Once all post its up step back and

discuss

• Are there any themes

appearing?

• Can we group issues?
• Are there any logical links

between risk and

• pportunities?

NOTE _ Please use the marker pens as we need to photograph the wall charts for the final report

Step 2: How could industry & government make this change a success?

• 5 top ideas for Industry and /
• r Government initiatives.
• Think across the entire new

build process / supply chain.

• Stick post it notes up on the

wall chart at the point most appropriate

• Discuss
• Are there any themes

appearing / can we group some?

• Ideas can be for

promotional activity / best practice case studies / shared R&D activities / planning incentives? etc. NOTE _ These ideas do not have to specifically relate to any of the earlier post its or groups. All good if they do but not essential.
