Minimise your building performance modelling time and maximise your productivity with DesignBuilder

DesignBuilder provides advanced building performance simulation software that minimises modelling time and maximises productivity. DesignBuilder is widely regarded as the most capable, productive, and easy to learn dynamic simulation software for building performance analysis.

If you are involved in any kind of building energy simulation, ASHRAE 90.1 modelling, BREEAM modelling, Green Star modelling (or similar forms of building energy certification), then DesignBuilder’s thermal modelling and energy simulation software can help you quickly produce the outputs you and your clients need.

From BIM to fully-integrated performance analysis, DesignBuilder’s whole building energy modelling software will meet all your needs, including: energy and comfort, HVAC, natural ventilation, daylighting, cost, design optimisation and CFD. Our high-productivity interface to the leading global simulation engines (including EnergyPlus, Radiance and now OpenFOAM) contains all the tools you need for fast and accurate building energy and thermal comfort analysis in an easy-to-use interface.

Calling all architects, engineers, researchers, sustainability and building physics consultants involved in building energy, comfort, and sustainable design modelling…if you are looking for fast and cost-effective building performance modelling software you need look no further!

"I have used DesignBuilder extensively both for certification modelling and for design work. Its template system, extensive libraries and custom certification tools – eg. for ASHRAE 90.1 or LEED daylighting – help to speed up time-consuming tasks. The software enables quick analyses of various design alternatives, helping to inform design decisions and find most cost-efficient solutions. What I find particularly useful though, is access to the EnergyPlus Energy Management System combined with custom DesignBuilder extension language. Using this scripting tool, models can be customized beyond standard software capabilities. This provides endless possibilities for creating sophisticated energy models and modelling virtually any real-world system or building element. Moreover, the Helpdesk staff provides professional and quick help – whenever I had become stuck with my models or encountered seemingly irresolvable issues the DesignBuilder team was always able to come up with right answers."

"I have watched the steady progression of DesignBuilder for the last 10 years or so, and having seen recent improvements in DesignBuilder’s HVAC and LEED modeling I decided to attend their training. I was both surprised and pleased to find how easy to use DesignBuilder is compared to the other similar tools I’ve tried, especially given the power and flexibility offered by the underlying EnergyPlus, Radiance and CFD engines. I’m really pleased that after a week’s training I feel ready to produce accurate results and outputs for loads and sizing calculations and energy analysis. The ability to also undertake fully-integrated daylighting and CFD analysis from the same model you use for loads and thermal simulations is also a very big plus point."
