Following on from previous articles where we explained the Passive House concept and Passive House and Technology. In this blog post we are going to be focussing on Passive House and BIM by answering the following question: what are the advantages of Passive House and BIM? Keep reading and find out how Passive House and BIM can help you to #ONEUPYOURBUSINESS!

WHAT ARE THE ADVANTAGES OF PASSIVE HOUSE AND BIM?

Building Information Modelling (BIM) is a process that begins with the creation of 3D models and is useful in providing document management, coordination, and simulation during each stage of the project. It is gradually replacing traditional design methods and the Passive House Institute has developed a BIM tool called bim2PH, which allows data to be integrated in 3D BIM software helping energy and design calculations in the Passive House Planning Package (PHPP). Below we focus on the advantages of Passive House and BIM:

  • Ensures Passive House design concept: with the designPH plugin you can add building geometry to create a 3D model interface and the advantage of this is it can provide feedback on the performance of the design allowing you to make improvements and promotes architects, designers, and all the relevant people to consider all aspects of the design in the early design stage
  • Improves energy efficiency: BIM can help in assessing energy-saving potentials, combining the designPH plugin can assist in understanding energy balances from buildings, street lighting, solar thermal energy, wind turbines, and much more. This can help with choosing energy supply options, the design of retrofit subsidies, and how energy can be saved allowing the improvement of energy efficiency and reducing greenhouse gas emissions
  • Provides accurate calculations: BIM provides accurate visual representations of buildings to provide different types of precise calculations such as areas, volume, and distances. This can guide designers to make their design decisions with confidence and meet the Passive House concept requirements and can use a IFC format to store geometry data and object properties from different domains also helping to improve workflow
  • Improves collaboration and workflow: due to all the documentation for the project being in a centralised location this improves collaboration as it helps everyone involved access information with ease and it enhances workflow by allowing the data to be captured efficiently during the process. This helps everyone involved to make any quick modifications, iterate between designs, plan and adapt quicker, and so on
  • Reduces material waste: as BIM can provide accurate calculations and measurements to provide precise measurements this help the design meet Passive House principles and accurately determine how much material is needed helping to the reduce extra materials ending up in landfills
  • Improves cost-effectiveness: since BIM can identify specific materials and components that you are using for your project, it can also help to estimate costs with more accuracy helping you to stay within budget and control your cost
