Our first collection of Revit content for Passive House design contains families for air handling units certified by the Passive House Institute.

By now we are all familiar with the perils of climate change and its relevance to the building sector. It has been widely reported that buildings are responsible for approximately 40% of global energy-related carbon emissions. In the UK, heating alone accounts for 10% of the nation's carbon footprint.

With demand for new buildings only set to grow in the years ahead, the construction industry faces urgent pressure to find new methods and technologies that can drastically cut its carbon footprint. Passive House is one such solution that is gaining in popularity.

About Passive House

Originally created in Germany (where it is known as Passivhaus), Passive House is not a new concept. It has been used for the past 30 years with a range of techniques to deliver net-zero-ready new and existing buildings.

The aim of Passive House is to provide a low energy use building. This is achieved by focusing on five basic principles:

  1. Removal of Thermal Bridges.
  2. Highly insulated envelopes.
  3. Airtightness.
  4. High performance glazing (triple).
  5. Heat recovery ventilation.

Scientific studies of Passive House buildings have shown that "Passive House buildings allow for heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared with average new builds – regardless of the regional climate."(1)

Revit Content for Passive House Design

We're excited to begin releasing collections of Revit content specifically for Passive House Institute certified components. These are building products that the Passive House Institute has certified as facilitating building designs capable of meeting international Passive House standards.

Our first installment focuses on the large ventilation systems used in commercial buildings that provide more than 600 L/s airflow. Typically these are large air handling units (AHUs) with a heat recovery system. In this week's collection, we have a series of air handling units from Menerga and Zehnder.

Air Handling Units from Menerga

We have six AHU Revit families for manufacturer Menerga covering its Adconair 76 and Resolair 64 models. The Adconair 76 Revit family comes with 10 types defined by their supply air flow.

The standard Resolair 64 model has been split into two Revit families due to construction and visual properties of the larger types, with five and three types respectively.

All of the Menerga AHU Revit families are available in left- and right-handed versions.

The families all have three levels of detail in 3D and 2D to provide appropriate views at different scales. The use of 2D geometry in plan view and elevations facilitates a fast workflow for the end user designing or coordinating in Revit.

Air Handling Unit from Zehnder

We also have left- and right-handed versions for the ComfoAir XL from Zehnder. These units come with six types driven by airflows, heating and cooling capacity.
