If occupancy calculation method is area/person and schedule is as below:
Until:5:00
0.05
Until: 6:00
0.1
Until: 7:00
0.25
So how to comprehend this? I mean how to identify how many people are in the building until 5 for example?Wed, 16 Aug 2017 12:53:23 -0500https://unmethours.com/question/26099/how-to-design-an-occupancy-schedule-based-on-areaperson-method-what-does-the-fract-00-or-005-or-02-mean/?comment=26103#post-id-26103Comment by David Goldwasser for <p>How to design an occupancy schedule based on area/person or person/area method?

(1.) The peak occupancy value (it's in the LOADS section under People definition (for ex: 200 sqft/person OR 0.005 person/sqft. (2.) The hourly fraction schedule (what you've described) where the values vary from 12am to 12am (generally 24 values for hourly schedule but can increase if you provide 15 min or 1 min scchedules).
Let's assume your space area is 1000 sqft, and the peak occupancy def: 200 sqft/person. The maximum number of people in the space can be = 5 persons (1000/200)
Later you need to define the total occupancy loads to the spaces (or spacetypes) where OS (or any other software) multiplies the peak occupancy (5 persons) to the fractional schedule. Let's say your fractional occupancy schedule is:
12am-5am: 0.0
5am-9am: 0.2
9am-12p: 0.6
12p-5p: 1
5p-12am: 0.4
OS will now multiply the peak occupancy to this fractional schedule to define the number of people in the spaces like this:
12am-5am: 0 person
5am-9am: 1 person
9am-12p: 3 persons
12p-5p: 5 persons (maximum value as the fractional schedule is 1)
5p-12am: 2 persons.

The occupancy schedule is based on the % of occupants that occupy a certain thermal zone at a given time. For example, in the weekday occupancy schedule example below, the office thermal zone is 95% occupied from 8am -12pm and from 2pm to 5pm. If you want the space to be fully occupied, you model it as 100% and if you want the space to be completely unoccupied, you model it as 0%.
![image description](/upfiles/15029070552494929.jpg)
This schedule can be modeled using a `Schedule:Compact` object. You would need to define the occupancy for all days. That is, define the occupancy for design days, weekends, holidays, etc.
![image description](/upfiles/15029070629951716.jpg)
The schedule above modeled in E+ looks like this:
(The line that says `Through:12/31` means that the same schedule is applied for the whole year. You can break the schedule for different months of an year if it is appropriate for your model.) You can look at an example file or I/O ref guide for details on how to model the `ScheduleTypeLimits` object for Fraction.
![image description](/upfiles/15029064143720498.jpg)
This schedule can then be applied to the `People` object. The occupancy schedule does not depend on how the occupancy is defined here. If you know the number of occupants for a thermal zone, it is best to model the occupancy using "People" as the `Number of People Calculation Method`. Sometimes, the occupancy information is available as occupant density (people/area or area/person) in which case, you can use the other options. Here is a thermal zone where the occupancy schedule above was applied:

Although, lighting schedules usually correspond to occupancy schedules, some zones might need lighting during unoccupied times as well. If you have access to ASHRAE 90.1-2004 User's manual, you can refer to page G-42 for typical office schedules. This document has schedules for a bunch of other building types.Wed, 16 Aug 2017 15:46:16 -0500https://unmethours.com/question/26099/how-to-design-an-occupancy-schedule-based-on-areaperson-method-what-does-the-fract-00-or-005-or-02-mean/?comment=26126#post-id-26126Comment by surajtalele for <p>Hi <a href="/users/2367/surajtalele/">@surajtalele</a> </p>

However, since we may have small (or large) approximations in the geometry, the calculated occupancy by the model may be slightly unexpected when you use area/person or people/area.Wed, 16 Aug 2017 14:45:27 -0500https://unmethours.com/question/26099/how-to-design-an-occupancy-schedule-based-on-areaperson-method-what-does-the-fract-00-or-005-or-02-mean/?comment=26121#post-id-26121Comment by surajtalele for <p>Hi <a href="/users/2367/surajtalele/">@surajtalele</a> </p>

It is very helpful. Only, my question is, if I define the number of people as occupancy calculation method and enter value as 10. and I want to model the zone occupancy at 95% ocuupied area then in schedule the fraction will be entered as 0.95 and to calculate occupancy at that instatnt this fraction will be multiplied by number of people i.e. 0.95 X 10=9.5 which is approx 10 is that right?Wed, 16 Aug 2017 13:42:49 -0500https://unmethours.com/question/26099/how-to-design-an-occupancy-schedule-based-on-areaperson-method-what-does-the-fract-00-or-005-or-02-mean/?comment=26111#post-id-26111Comment by surajtalele for <p>Hi <a href="/users/2367/surajtalele/">@surajtalele</a> </p>
<p>The occupancy schedule is based on the % of occupants that occupy a certain thermal zone at a given time. For example, in the weekday occupancy schedule example below, the office thermal zone is 95% occupied from 8am -12pm and from 2pm to 5pm. If you want the space to be fully occupied, you model it as 100% and if you want the space to be completely unoccupied, you model it as 0%.</p>

<p>This schedule can be modeled using a <code>Schedule:Compact</code> object. You would need to define the occupancy for all days. That is, define the occupancy for design days, weekends, holidays, etc. </p>

<p>The schedule above modeled in E+ looks like this:
(The line that says <code>Through:12/31</code> means that the same schedule is applied for the whole year. You can break the schedule for different months of an year if it is appropriate for your model.) You can look at an example file or I/O ref guide for details on how to model the <code>ScheduleTypeLimits</code> object for Fraction.</p>

<p>This schedule can then be applied to the <code>People</code> object. The occupancy schedule does not depend on how the occupancy is defined here. If you know the number of occupants for a thermal zone, it is best to model the occupancy using "People" as the <code>Number of People Calculation Method</code>. Sometimes, the occupancy information is available as occupant density (people/area or area/person) in which case, you can use the other options. Here is a thermal zone where the occupancy schedule above was applied:</p>

That was also my concern, because, while designing thermal zones I have simplified some of th geometrical areas because its irrelevant to provide too many architectural detials in energyplus input. And I specifically have a certain number of occupants in my mind which i would like to consider in simulation. So, direct input looks like a good approach to me.Wed, 16 Aug 2017 14:49:43 -0500https://unmethours.com/question/26099/how-to-design-an-occupancy-schedule-based-on-areaperson-method-what-does-the-fract-00-or-005-or-02-mean/?comment=26122#post-id-26122
