Hi, i´m from Venezuela ( nobody uses energy models for buildings) and i am using eQUEST for my gradework.
I have problem to import Weather files
-I got weather file (Caracas) from METEONORM 5.1 in a lot of formats. How can i do to view the correct header of these? or how can i know that i am puting a correct headers. I need to see a template for all the formats.
Thank you

Subject: Re: [Equest-users] shading schedules ？
Another general tip/reminder: first thing you should do after encountering an input field you are uncertain of is to right-click the field to check whether there is a corresponding help entry for that specific item. In this case:SHADING-SCHEDULETakes the U-name of a SCHEDULE (with TYPE=MULTIPLIER) that defines hourly values of a multiplier on the solar gain through the window. This represents the shading effect of movable devices such as blinds, drapes, or shutters. Items that change solar transmission may also affect heat conduction. If so, a matching CONDUCT-SCHEDULE should be used. If the SHADING-SCHEDULE is not input, the schedule will default to 1.0 for all hours.“Solar gain” is the load incident on a space as a result of the sun/sky’s energy entering through a fenestration and being absorbed/interreflected by internal surfaces (floors/people/furniture…), manifesting as heat radiation in the process. If you have a window device or seasonal treatment that varies not only the light coming in but also appreciably affects the conductive transfer of heat through the window/frame opening, then define a CONDUCT-SCHEDULE as well to account for those effects. An aside to clear up a potential source of confusion: building shades can optionally be given a SHADE-SCHEDULE, which is in practice/function very similar to a SHADING-SCHEDULE for windows.

Subject: [Equest-users] Modeling Inclined walls in eQuest
Hi,
I am modeling a fully glazed building with inclined walls. In fact, the building envelope is in the form of a globe or like a sphere. Can anybody suggest how this can be modelled in equest.?

Subject: [Equest-users] Multiple Heating Hot Water Loops
How do you model
multiple temperatures for various heating HW loops such as radiant slab
(120/constant temp) vs. HW loop (160/based on OA reset) for any type system
if they are all coming from the same boiler plant?
Do you provide a
heat exchanger on the peripheral loop to account for the different
temperature?

Subject: Re: [Equest-users] Modeling Inclined walls in eQuest
Not easily. Critical details aside, I expect constructing a full 3D globe in eQuest would be a pretty major challenge for most of us. I’ve done some complicated curvilinear 3D shapes in the past (isolated helical building shades and similar), but those efforts required much time absorbing all the math involved in describing that shape in order to produce formulae in a spreadsheet to generate the correct polygon vertices and format them in a fashion such that they may be copy/pasted or imported into an .inp file. Achieving a full globe would likely require a different approach – perhaps a geometrical import via green building studio or referencing a 3D model while defining each facet polygon in detailed mode… I’d personally ask around to see if others have tread a similar path to see if it seems feasible first. …But that’s only my opinion ;). ~Nick NICK CATON, P.E.SENIOR ENGINEER Smith & Boucher Engineers25501 west valley parkway, suite 200olathe, ks 66061direct 913.344.0036fax 913.345.0617www.smithboucher.com From: equest-users-bounces at lists.onebuilding.org [mailto:equest-users-bounces at lists.onebuilding.org] On Behalf Of Anoop Vijaykumar

Hi Nick,
Thanks for your inputs...yes, this seems a major challenge. I was thinking of creating a dummy floor in between (with 'open to below') and give inclined facades..but I doubt if there are any options in eQuest for inclined or angled facades..in between I read from one of the forums that it can be done in DD Edit...!!! still trying to find ot out, any idea if that option is available in eQuest..?
And yes, I need to try it GBS and IES too....I would also like to see anybody here in our community has done similar models with slanted facades/spherical structures etc....
Many Thanks,
Anoop.

Subject: Re: [Equest-users] Multiple Heating Hot Water Loops
eQuest allows you to create secondary loops with different design temperatures. Right click on project, create a new circulation loop of type Hot Water, choose secondary subtype, select the primary loop and specify your design temperatures. It will use a 3-way valve to mix down the temperature you specify. There may be a couple steps I’m forgetting, but this is the general direction I head in.

Anoop,
If you are modeling against an energy standard, be sure to check when your inclined “wall” becomes a “roof”. In 90.1-2007 a roof is “horizontal or tilted at an angle less than 60 degrees from horizontal”.Regards, Paul Riemer, PE, LEED AP BD+C Associate / MechanicalDirect: 612-465-7696 DUNHAM From: equest-users-bounces at lists.onebuilding.org [mailto:equest-users-bounces at lists.onebuilding.org] On Behalf Of Bishop, Bill

Subject: Re: [Equest-users] shading schedules ？
I sense a vocabulary jumble… I don’t consider myself an expert in the science of window performance, but I think sharing my understanding may help you in this case: ‘Shading Coefficient’ is a property that describes how much solar energy passes through a glazing relative to single pane clear float glass*. Strictly speaking, it does not include frame or other opaque elements, but sometimes by context people will discuss an SC for an entire window assembly... SHGC is more commonly used to describe “whole assembly” performance. Fractional shading schedule values in eQuest define how much light gets through an entire window assembly, relative to the same assembly having no additional shading device at all. They’re similar in concept, but not quite the same thing… I would encourage you to google the terms and feel comfortable understanding the difference before choosing a course of action. This article looks promising: http://www.commercialwindows.umn.edu/issues_energy2.php ~Nick * Newer eQuest users: note Glass Type #1000 in the DOE2 Glass Library (accessible in the context menu after right-clicking most fields and after ‘Tutorials and references’) is this exact case: SC = 1.
