Hi Francois,

If you have a complete hourly data set for a site you could try with EnergyPlus Translator, as Andy wrote in a similar previous topic:

“If you plan to do serious weather file transl ...

DB draws automatically holes into walls precisely to insert interblock partitions. But in fact, there is just an inter block partition construction between two adjacent blocks. If you change the const ...

Hi Leone,

I think ‘Radiant heating’ is equivalent to the ‘Zone heating’ concept you can find in DB help, just that it expresses precisely that is radiant heat. As far as I know, to model local heat ...

Hi Bernd, welcome to DesignBuilder!

It seems we all are very busy right now Smile

. Well, here is my modest attempt:

1. I have not much experience in this field, but... you can find detailed inform ...

Hi Carlos,

Some points:

First of all, you are modeling each house as a block into a 'building'. I don't know if it is your intention, but is very advisable to model each house as an independent ...

Hi Margherita

I drew on surfaces, for every zone, all the windows with right dimensions of the projects, but sometimes it happens that some windows change dimensions.

It is very curious, I had n ...

Hi, Margherita, welcome to DesignBuilder!

Current versions of DesignBuilder only allow editing openings at surface level, so all openings into a surface will share the same parameters. There are so ...

Jacopo,

I’m not sure to understand your question. If you are trying to model something like a box inside another one (with different height each one) you could try this approach:

1. Draw two blo ...

Hi Daniel,

Some thoughts:

1. and 2. There are two ways to merge zones: by holes and by activity. Possibly you will need to use the former, drawing as many zones in the upper block as in the lowe ...

Hi all,

About Rahmi questions:

1. I used theoretical comfort temperatures for each month calculated with a simply formula, e.g. thermal neutrality (Tn = 17.6 + 0.31 Tave).

2. If you are refe ...

Hi Rahmi,

Ground monthly temperatures (site details) are temperatures in external surfaces of every construction adjacent to ground. Those temperatures could have great influence in thermal perform ...

Dear all,

I want to share my own little experience in this topic.

We could describe the center of the problem as follow: the building affects ground temperatures beneath it, and ground temperat ...

Javier,

DesignBuilder uses EnergyPlus calculation engine , so I think you can find the required information into EnergyPlus documents, specially the Engineering Reference manual. You can get this h ...

Mike,

If I understand your question, you could try this approach:

1. Draw a central zone into the block (central space). It is a good idea to draw very thin partitions. See figure 1.

2. Set f ...

Mark,

Just to add…

DesignBuilder allow you to draw custom trapezoidal windows. You can set shape as polygon in Tools > Perimeter.

Best regards
