To check, in the same window, if you select the new material under ‘assigned construction types’ the windows should now appear red in the preview.

Under ‘ Possible replacement construction types‘ choose the material you wish to assign to.

Choose the material the windows are made from at the moment.

Under ‘ Assigned construction types’, we can select all windows made of one kind of glazing within the geometry we’ve selected.

Under ‘ Select construction category‘, select External glazing.

Click Assign Constructions (small yellow button, centre-top).

This geometry should appear red when selected.

Select your geometry which contains the windows you wish to edit – you can choose a wall or a whole room for example.

Applying a construction to existing geometry If we already have a window drawn and we want to change its construction, we need to apply it. Now, whenever we draw a new window, it will be assigned the properties of the window construction we just created.

Under Select Construction on the right, for External Window, we should find our new window in the drop-down box.

Press OK a couple of times when happy and return to the Building Template Manager.

Create your construction in this window – each row in the table is one layer of material, outside to inside.On the new one (probably coloured purple), right click and select Edit construction.Right-click on a similar construction and select Duplicate Construction

Usually it’s easiest to create a new construction by duplicating an existing construction and then editing it.

On the bottom, select the category, such as Glazed for adding a new window.

In the bottom, click Apache Constructions Database (small yellow button).

Go to Building Template Manager on the top bar.

The power and flexibility of EnergyPlus, the underlying simulation engine, enables us to model a building in fine detail where required so that we can accurately analyse its performance. Please see our Comparing Energy Saving in IES page in order to see the actual energy savings that the e-stack system has over the alternative of preheating incoming air or using MVHR instead of a natural solution.Example: create a new window type and apply it to a window in an existing model Create new construction The data management structure (data hierarchy and inheritance) allows us to assign model data quickly and accurately, improving our efficiency. So the e-stack system will look the same as any other natural ventilation system in terms of heating energy consumption, because the need for preheating is disregarded by traditional modelling techniques, which only take into account the bulk air temperature.

However as thermal modelling software and building regulations do not take account of thermal comfort in relation to draughts any energy input to mitigate cold draughts does not need to be included. To accurately model conventional natural ventilation systems, preheating at the low level openings would have to be incorporated. Instead we operate in ‘mixing mode’ where we bring in air at high level and mix it with warm room air to create a tempered air stream which is comfortable for occupants. The main advantage of the e-stack system over other natural ventilation systems is that in the winter, we do not bring in air via opening windows, as this requires a large amount of preheating energy. If you have any queries whilst modelling your building with e-stacks please contact Breathing Buildings directly and we will be happy to help!

We have provided a set of PDF user guides on modelling e-stack natural ventilation systems in EDSL TAS software.

Instructions on how to model the different ventilation profiles are also available to download and the profiles themselves are embedded in the. Different geometry is provided for the e-stack R-Series, S1200 and S1500 units. The geometry of our roof mounted stacks is available as a. Users of other dynamic thermal modelling tools can contact breathing Buildings directly for modelling instructions. The following instructions are for those modelling e-stack ventilation systems using IES-VE or EDSL’s TAS software, they are suitable for use primarily for overheating modelling, but also Part L compliance modelling.
