eQuest is my all time favorite for energy modeling
Us In California are stuck useing energy pro or cbec.com, basically you build your model press calculate and hope it run without errors. Then when it runs half the time you get to spend several hour fudging the number to get compliance. Trace is a pain in the but butt although I find it to be one of the most accurate and detailed that I have used.
Arpan: The votes are in. Sefaira is Style AND Substance
Hi Everybody from Russia! Equest 4 EVA! We will soon all go back to 2D modeling, 3D is not reality
While some commenters, they might be teasin'
To me, Sefaira's the only one that's pleasing.
For I, a humble project architect,
Am finally empowered to connect
my audience with graphics that add value,
and that's important, let me tell you...
Sefaira lets me compare strategies super fast
to beat my competition at long last.
Now, I'll keep admiring my mech engineers
Your sizing and compliance deserve all of our cheers!
Instead of making purpose driven models that take days,
in Sefaira, I load up my SKP and RVTs - that's the easy way!
For I know that when the competitions deadlines loom,
the one software that will save me from project doom,
the one to compare daylight & energy in seconds flat,
with a great UI and even greater support (if I need that),
the one that'll get my rah, rah, rah--
Is my one and only Sefaira!
I would like to remind everyone here to be civil. Also, did you know that IES's internal engine name is "slowcore"? That is all.
Andrew, thanks for the mention of EDSL's TAS software. We have come a long way in the last 4 years with regards to capabilities for the US market. We have a new innovative plant and controls design application with fast multiple-core enabled simulation. We are still fast and robust. Best, Michael Sawford (EDSL)
Dear Adam T
Thank you for your comments. I'm the product manager at Sefaira (and a very experienced energy modeller too who has used a lot of these products!)
It's unfortunate you or your firm got the impression Sefaira is for UK compliance. It is not and as far as I know there is nothing in our sales or marketing literature that says so.
Sefaira is designed to make it easy for all design practitioners to do quick efficient studies up to around the end of schematic design.
I do not know of any of our customers who have genuinely tried to use Sefaira for a code submission. It would be hard.
The whole point of sefaira is to be fast and easy to use. This makes it good when there is a lot of change and not much fee for doing analysis.
For us it's really nice to see our product somehow get voted as "favourite interface" because we put a huge amount of thought and effort into that interface. We try really hard to make our layout intuitive so our users don't need much training and have specialists on the team whose job is just to optimise that aspect of the product.
I'm my mind there is a good case for different tools at different stages of the project. As a consultant I almost never carried the same TAS model from SD into DD and I'd be lucky if the results matched between stages. If that sounds familiar why not use a faster tool at SD?
So in short our goal is to offer people a way to save time and have fun doing concept and Schematic analysis.
Again my apologies if you bought it looking for something else. Feel free to reach out directly if you'd like me to walk you through how it could bring value to your business in different ways.
Best regards,
Andrew Corney PE, MASHRAE, MCIBSE.
Product Director, Sefaira
IES is best I can use a poll too! hahahahahahahahahaha
Very mature
Hahahahahahahahahaha
I too would like to propose another poll
You'll be my soft and sweet
I'll be your strong and steady
You'll be my glass of wine
I'll be your shot of whiskey
You'll be my sunny day
I'll be your shade tree
You'll be my honeysuckle
I'll be your honeybee
;)
Anantaditya I don't think another poll will help.
Clearly some companies have diverted some of their employees attention away from offering good service and getting trigger happy on this poll
What a waste of time.
Interesting results...My company tried Sefaira after they were claiming it could be used for UK Regulations on their website. We were interested, but after using it we quickly found it was not suitable as it wasn't approved software. In fairness, when we asked about this they said the claim was for early stage design towards UK Compliance. But that is pointless if you want to go from start to finish. Why would we pay only to go and use SBEM in IES which is approved for UK Regs, and they give away for free?
For design Sefaira was ok, but to me it didn't have the flexibility or substance that IES-VE offers, that we're used to. The amount of detail you can get into by using it still makes my head spin.
I get this may be off-putting to architects or M&E consultants, who from speaking to, seem to only be interested in a quick result, and not in truly validating their great designs.
My company attended the CIBSE TM54 talk where IES were putting across their case about closing the performance gap and the tools they are developing to help us do just that. Using these tools we envisage real time, real numbers from which we can suggest real solutions.
At the end of the day we should all be gunning for great performing buildings that reduce our clients operation costs and therefore save them money, something that can be quantified. For us that is the holy grail and I hope to see more of this from other software too.
Sefaira+EnergyPlus = une combinaison formidable! J'aime Sefaira, c'est un interfaz tres fort.
TRNSYS est un outil ouvert, modulaire et complet
Hey IES Fan - I used to think the same thing. The truth is that pretty graphs backed up by a powerful engine (EnergyPlus), with comparative cloud simulations done in minutes NOT DAYS, is what sells projects and builds business. Those projects pay your salary. That's why I use Sefaira. It has paid off for our firm in spades.
The modelers mantra: Use the right tools for the job. There are many jobs, and many tools. It takes experience to know which tool to use, and when. But keep an open mind. IES was also new once. By the way, I also use IES and HAP, but Sefaira has saved my backside many more times, especially since I don't need to remodel architecture models all the time. So maybe reach out to the Sefaira team - they really know their stuff, amazing support team.
Sefaira is based on EnergyPlus, Radiance and DaySIM. It's wickedly fast, and has better integration with Revit and SketchUp than any other application listed here. It has doubled our business in the last four years. Learn the facts before making uninformed comments.
IDA ICE is not only the best interface, but also by far the newest technology! The equation based system offers a maximum of flexibility which is unreached by any other tool! Additionally you can simulate envelope, HVAC systems and control strategies all together in one shot! The adaptive timestep is another key advantage compared to all other tools, also the Drag&Drop, Copy&Paste and visualization possibilities! Watch this: https://www.youtube.com/watch?v=1zmVZy6_rWU
Check the website or get in touch with me to learn more! ;)
Sefaira!! Has anyone else actually compared the results to a real modelling software - you may as well pluck a number out of the air and make a pretty graph from it!
Ida Ice is superb for HVAC-designers, product delopers and energy resesearchers. It is irreplaceable in developing new energy effiecient HVAC-systems. If it works in Ida it works in reality.
aha! what the matter!
no
amazing
Yes
All software have their own characteristic in energy modeling
We should really have another poll.
My comment was deleted. That doesn't seem right. Free speech is a fundamental tenant of the intranet and many of nations represented in this poll.
I see ESP-r was added to the poll, even a bit late. Too bad I already cast my vote a few days ago.
Designbuilder is the winner !
Arpan Bakshi, why did you stop the poll? You promised us that you would keep this open until the Spring Equinox yet instead you closed the polls SIX days early (Spring Equinox is March 20th). We the people demand answers: http://energy-models.com/forum/discourse/general-discussion/polls-open-vote-your-favorite-energy-modeling-interface
I vote we have another poll.
winner
IESVE is the Donald Trump of this poll
Write me in!
Good
Designbuilder, Great!
It's excellent
Good
Interesting.

l lik you
Excellent tool for professionals and academia as well. Efficient and intelligent tool.
Very good
Good
Ies
Wish you iesvs
openstudio saves time while creating surfaces and other geometric elements; I switch to idf editor once geometry is ok.
It is excellent
Best interface, All modules and navigators stacked in the most logical and splendid way to enhance user experience.
Glad to see Revit/GBS is exactly where it belongs, bottom of the barrel. Even though it is included with Revit, I've never met anyone who actually uses it.
.
How much do you have to love your interface to write a rhyme in its honor! #BillyPiper
Interface does not equal engine! Good poll though.
Honey to the bee that's you for me
I wouldn't tell a lie got a love I can't deny
Honey to the bee that's you for me
May be opportunity for testing all above special usage chance I want to have.....
