DesignBuilder is a modular suite of design tools that plug in to our 3-D building modelling software. We have a set of convenient packages that suit most needs, however you can license individual modules in any combination you require. You can also license additional modules to increase the capabilities of the entry level packages as and when you need them.

Annual or Version Perpetual Licences

DesignBuilder offers a choice of annual or version perpetual licences. An annual licence has a lower upfront cost but must be renewed each year to continue using the software. This allows you to stay up to date with the latest release of DesignBuilder with no upgrade charges. Certification and Energy Assessor licences are only available on an annual basis as they need to be continually updated in line with building regulations. A v6 perpetual licence allows you to continue using v6 for as long as you wish, however if you wish to upgrade to v7 when it is released you will need to purchase an upgrade. DesignBuilder offers a 40% upgrade discount in this case. Email support is included with both licence types. See our Support Desk Policy page for more details.

Single User License

A Single User licence allows you to run one copy of DesignBuilder at any one time. The software can be installed on any number of computers and moved from one to another. This is the simplest and most common licensing option, suitable for individuals or small teams.

Site Network License

A site network licence is the most convenient way to share one or more licence across a number of networked machines. The site licence server is installed on your network server and provides module licenses on demand to DesignBuilder users on your network. This is a more cost effective option for larger numbers of seats but does require a little additional effort to set up and administer. With a site licence, individual DesignBuilder modules are ordered in quantities sufficient to support your concurrent user requirements. To purchase site licences please contact DesignBuilder sales or your international reseller.

Evaluation Licence

You may obtain a free 30 day single user evaluation licence to trial DesignBuilder. This will allow you to access all the modules. You may also apply to us for an evaluation extension or to trial modules you did not use during your original evaluation period.

Education and Student Licences

We provide discounts for educational users and affordable student licences on application and proof of status. Academic institutions that purchase a site network licence for teaching use on the department network can be provided with a number of free single user student licences for use on students own computers. Educational and student licences cannot be used for commercial work or consultancy - a full licence is required for this.

SBEM Pay As You Go Licence

This is a low cost of entry licence for occasional SBEM users or for organisations with many affiliated energy assessors. Pay as you go licences allow the certification module to be used on any number of computers. Each time an SBEM calculation is run to generate a new EPC or Part-L calculation, a pre-purchased credit is deducted.
