a part of it,,,, plz find the file attached and tell me if there's a problem i can't recognize ?
the energy plus Icon tells me to update honey bee & I updated it but no results .
for the simulation results I need for my study :
- air temperature in side the building
- thermal comfort analysis
In 3 cases " when the kinetic facade is closed , 50% open & 100% open " then I need to make optimization to get the optimum movement of the facade .
so I need to know what's the problem with my file !!! and if there are advises for the next steps of my study will be great .
and I have a question , honey bee can deal with windows , but what about doors ? how to have a correct results with no doors in the building ?
thank you in advance

cs algorithms are ill-suited to calculating the transmission of a partially open screen. The sampling of rays required, and indeed the lack of actual wave-based movement of sound intensity makes them only suitable for large scale studies of spaces making the following assumptions, among others:
- The primary behavior of sound can be described by rays
- Diffraction lends only low significance effects
- Few, preferably no obstructions between the source and reciever
With regard to sound hitting a partially open screen, a variety of behaviors come into play. Sound moves in and out and around various points of a screen - meaning that rays can not describe the behavior of sound for such small delicate structures.
The good news is that some of the latest versions of Pachyderm also employ numerical methods. Try typing "Pachyderm_Numeric_Timedomain into the command prompt, and you'll get the controls for the Finite Volume Method. This method accounts for wave-based phenomena.
Now more bad news: The method does not have implemented an insertion loss calculation, so you would have to work in the source code to implement it, and it still does not have materials implemented (that last part may not be terribly important unless you intended to use porous sound absorptive materials).
So, in any case, I don't recommend using Pachyderm to determine the sound transmission of your design. Now for some more good news - you can do a rough calculation on a calculator, making a few assumptions, if you know the open area of your screen. Let's say that we assume your materials do not transmit at all (which they won't, but they will transmit far less than any opening in the screen). So let's assume you design a 50% open area screen. The transmission loss of the assembly, independent of octave band will be at most:
TL = 10*log10(0.5) = 3 dB
This means that the noise from your source will be 3 dB less on the quiet side of the screen than it will be on the railway side of the fence. Let's say that isn't enough... ok 20% open.
TL = 10*log10(0.2) = 7 dB
So now it is 7 dB less on the quiet side than it is on the rail side (it will probably be up to 3 dB louder at low frequencies, but this is a rough estimate).
So now the last bit of bad news - it is difficult, maybe impossible to get a strong amount of attenuation with a screen with open area. Even with a wall with no open area, the maximum attenuation will be 20 dBA. When you open it up, this will severely hamper the isolation of the screen. I hope this helps.

cy of design communication and the control of information-flow are as important as the creativity of ideas. In response to the concurrent digital evolution emerging in the architectural industry world-wide, the Faculty of Architecture at The University of Hong Kong will host a two week intensive summer program named Digital Practice.Led by professors from The University of Hong Kong, as well as invited practitioners with expertise in practice of cutting edge digital techniques, the program offers participants opportunities to experience applications of computational tools during different stages of an architectural project, i.e. concept design, form finding and optimization, delivery, management and communication of design information under the team-based working environment. By learning advanced computational techniques through case studies in the context of Hong Kong, participants are expected to go beyond the conventional perception of technology, considering users and tools as a feedback-based entity instead of a dichotomy. The program, which is taught in English, includes a series of evening lectures related delivered by teaching staff and invited local architects.對於高品質的建築專案,創意之外,專案過程中高效的設計資訊管理和交流成為項目設計深化和實施必不可少的環節。今天,數字化技術不但改變了建築師的繪圖工具,影響了設計的過程,而且提供了工程建造和管理實施的更有效、更高效的手段。針對建築的數位化演進,香港大學建築學院將於2011年暑假期間,在香港大學建築學院舉辦“數位化實踐”國際研習班。在香港大學建築學院教授及有著相關豐富經驗的外聘實踐建築師的指導下,學員將有機會體驗在專案的不同階段(如概念設計、設計形式的生成、優化,設計資訊的管理和交流),如何有效地應用各種運算智慧化技術(從設計的數位化生成和建築資訊類比到物理模型),提升設計實施的品質,增加設計團隊對於方案的控制。我們將挑戰對於“技術”的傳統認知,即相對於使用者它不僅是工具,更是與使用者互動的媒介,二者形成一個有機的合體。研習班期間會安排系列講座,展現數位化技術在實踐工程中的廣泛應用。…
summer because of the relative humidity of outdoor air will be over 80%.
I want to set the schedule like this
1) cooling setpoint to be 27C degree and max humidity to be 50%.
2) when the outdoor air temperature is lower than 27C, open the windows and ventilation naturally.
3) Air conditioning and dehumidification are needed only when the occupancies are at home (almost at night) and Natural ventilation is not to be.
4) Accept the indoor air relative humidity to be almost 100% when dry bulb temperature is lower than 27C.
Now, I set the air conditioning schedule as cooling setpoint schedule, but there are no components to set a dehumidification setpoint schedule.
The dehumidifier keeps working all day whichever the windows are opening or not.
How can I stop the dehumidifier during the windows open?
thank you.…
he Summer in the City program, part of the Portland School of Architecture and Allied Arts (an extension to University of Oregon).
Using both Grasshopper and the Firefly plug-in, this workshop will focus on the design of innovative facade prototypes that are configurable, sensate, and active. Students will become familiar with the terminology used in interactive facade design including an overview of hardware (ie.sensors, actuators, and programmable microcontrollers) as well as software interfaces terminology. We'll learn new prototyping techniques and develop digital and physical models which can respond to a plurality of environmental and user driven forces. This workshop will take a hands-on approach, and you will walk away with the ability to build your own custom electronic circuits (using the Arduino), as well as create interactive simulations and models.
This course will primarily focus on physical computing techniques. Unfortunately, given the time constraints of the workshop, I will not be able to provide an extensive overview of the Grasshopper interface (it is suggested that participants have some familiarity with the Rhino/Grasshopper environment). There are many great online resources to get you up to speed relatively quickly if you are new to this software. This is a good place to start.
The course will be held at the School of Architecture and Allied Arts in Portland, OR. The date/times of the workshop are as follows:
Friday July 19, 5:00-7:50 P.M.
Saturday July 20, 9:00 A.M.-3:50 P.M.
Sunday July 21, 1:00-3:50 P.M.
If you are a designer, architect, or anyone who is interested in learning about the digital tools and technology trends that are revolutionizing design today, this workshop is for you. Make sure to click here to find out more about registration and enrollment in this exciting new workshop.…
g energy use of electric lighting dimming system.
But I found a major mistake in my previous test file, that is, the "lighting Power" used in the daylight simulation and the E+ simulation are NOT equal by my carelessness. The former was 250w (default value in "Honeybee_Lighting control Recipe") while the later was 11.8403571*50=592.018w (lightingDensityPerArea*Areaoffloor=lightingpower).
Having corrected this mistake (by using 592.018w for both of them), the results of electric lighting energy obtained from daylight and E+ simulations are much closer with each other and more reasonable. In order to see how close they are, I made 3 tests using 3 different weather files (New York, Amsterdam, Guangzhou). The results are listed as follows respectively:
New York (3.4% difference)
Amsterdam (2.7% difference)
Guangzhou (3% difference)
It seems that the difference (around 3%) is acceptable?
You are right. Having checked the IDF file created, as you mentioned above, there is no data in the Daylighting class (since the daylight control are not implemented in the E+ simulation). But, the light is "fully/partially" on according to the "fractions" in the generated lighting schedule list, which already takes in account the dimming system by the setting in "Honeybee_Lighting control Recipe" in daylight simulation.
Then, what the E+ simulation did in terms of calculating electric lighting energy use is just as the following formulation: lightingDensityPerArea * Areaoffloor * sum of lighting schedule list (generated by daylight simulation in this case) = electric lighting energy use, which has been verified by the comparison of results obtained from E+ simulation and calculated by the above formulation. (The results are exactly the same.) Please see the updated gh file attached.
Therefore, I assume that the E+ results generated in this way (using the lighting schedule generated by the daylight simulation) are still reliable, although there exist some tiny difference (around 3%) for some unknown reason (Maybe Daysim does not follow the same formulation mentioned above? Can you imagine the possible reason?).
In addition,
- I am not clear with what you mentioned as "they definitely don't share daylight considerations". What "daylight considerations" here refer to? (sky condition / sky file? but in the annual Daylight Simulation, only weather file is required instead of sky file)
- A basic question: In E+ simulation, has the waste heat generated by the electric lighting been considered as "internal heat gain" (showed in the above image)? If so, can I say that "energy use for electrical light" is fully converted to "the waste heat" + "Illuminance in lux".
Namely, energy use for electrical light = the waste heat + Illuminance in lux (lux can be converted to electric power in watts)?
Many thanks!
Best,
Ding…
