For building developers and architects aiming to create buildings that are net-zero, in line with the government’s mission of achieving net-zero by 2050, the latest technological advances in building simulations and modelling can help. 

Building simulation and modelling software helps create building designs that give an accurate representation of not only the design but also its impact on the building’s efficiency and energy usage. Through these 3D models, developers can more accurately construct a building that meets net-zero goals.  

In this article, we will discuss how net-zero can be achieved through building simulation and modelling software and how this links to a ‘fabric first’ approach. 

Fabric First Approach and Building Simulations 

Building simulation also ties in well with the sustainable ‘fabric first’ approach to building design. A ‘fabric first’ attitude is where designers maximise the performance of the building’s components and materials before considering the use of mechanical or electric service systems.  

Improving energy efficiency and reducing carbon emissions through methods such as maximising air-tightness, using super-high insulation, and optimising solar gain, means owners can reduce capital, operational and maintenance costs in the long term. 

What Building Simulation and Modelling Software is There? 

There are multiple service providers for building simulation software such as IESVE and DesignBuilder. 

These comprehensive tools allow you to model complex building structures within the simulation enabling you to create an energy-efficient design and continually optimise it. 

This advanced technology provides architects with the ability to carry out ‘sustainable master planning’ and delve into zero-carbon energy design whilst also modelling the impact of every change they make to the overall energy statement of a building. The simulations respond and behave like their real-world counterparts and function as problem solvers in order to support decision making. 

Overall, building simulation and modelling software allows building designers to visualise integrated data and analyse it in order to construct and operate buildings more efficiently and effectively. 

How Does Building Modelling Help You Achieve Net Zero? 

Modern and dynamic building simulation models can provide more value than just creating a digital design of the building. They also provide the relevant analysis and impact management needed for making important decisions about the construction of the building and its lifetime carbon emissions. 

Building modelling will surely become increasingly important as we navigate the transition to clean energy sources helping to provide answers for how and what energy will be needed now and in the future. It is an incredible tool to give some real tangibility to the benefits of zero-carbon initiatives due to its accurate predictions and visualisations. 

Virtual building modelling, therefore, can help architects and construction professionals to achieve net-zero by enhancing our ability to design for efficient energy consumption and benefit from the real-time analysis and optimisation of the internal building structure and external environment. 


Simulating for a 2050 net-zero carbon world requires major advancements to the current way our buildings and cities are designed and constructed. The outstanding features of building simulation and modelling technology must be fully implemented to create a fully sustainable building sector.
