[esp-r] Re: Radiance coupling and control of BSDF shadings

[Arianna Sdei]

Dear German,

I am planning to start modelling some shading types with ESP-r as part of my PhD very soon and your email at this time is so relevant. I am planning to model venetian blinds, roman blinds, simple overhangs and awnings. My aim is to find the cooling load reduction when these types of shading are used in the summer. There may be an energy increase due to the use of artificial lighting. That which may involve a detailed daylight study using radiance. I would like to also work on the opening-closing of these systems. It looks like you are doing a very detailed study and I would like to know more about it, I hope we can do some work together, please do get in touch.

Thank you,

Arianna

Subject: [esp-r] Radiance coupling and control of BSDF shadings

Dear everyone,

I am thinking on coupling Radiance with ESPr using the Three-phase method. The plan is simple: Make a detailed simulation on Radiance, and create a schedule of artificial lighting power (energy consumption / internal gains) and, somehow, shading control.

On the lighting power part, I was thinking on creating a Zonal Casual Gain File, that will account for the internal gains generated by the lighting. Is this valid? should it be just convective? radiative?

On the other hand... in a recent e-mail I was told that ESPr can use Bidirectional Information (probably extracted from LBNLs WINDOW software) to make simulations; but, since a big advantage of the Three-phase method is to allow easy control, I was wondering if it was possible to, on each timestep, modify the BSDF information (accounting, for example, opening or closing blinds) on ESPr.

Anyway... consider this an open topic, and please feel free to comment. I know I am not the only one who has thought about these topics, so you experiences will be very welcomed.

THANKS VERY MUCH

German
