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 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 on 2 nd April Design SAP 2012 allows modelling of dwelling types in anticipation of Section 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 can be automatically updated to Section For a free, 30 day demo of Design SAP 2012 please call or Read more about our Design SAP software herehere

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 opportunities? 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 / or 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.
