1
00:00:00.300 --> 00:00:03.303
This video will go over the HVAC form.

2
00:00:04.137 --> 00:00:07.140
You will get to this form
by clicking on the HVAC

3
00:00:07.140 --> 00:00:10.410
or HVAC link from the energy Audit

4
00:00:10.410 --> 00:00:13.413
Input menu section as I am doing now.

5
00:00:14.080 --> 00:00:17.083
Building HVAC systems are both diverse

6
00:00:17.083 --> 00:00:20.520
and potentially very complicated. As such,

7
00:00:20.653 --> 00:00:24.824
this BAT section includes
submenus for various important building

8
00:00:24.824 --> 00:00:26.760
HVAC subsystems

9
00:00:26.760 --> 00:00:30.830
as seen by the additional buttons
on the left side of the data entry screen.

10
00:00:31.331 --> 00:00:33.600
When you first click the HVAC menu,

11
00:00:33.600 --> 00:00:36.569
you will be brought
to the heating plant page.

12
00:00:36.569 --> 00:00:41.541
But first we will discuss
what is similar across all entry forms.

13
00:00:42.342 --> 00:00:45.345
Generally, floor spaces and zones

14
00:00:45.545 --> 00:00:49.382
are available for defining the area
served by these systems

15
00:00:50.016 --> 00:00:54.587
and will be a big driver
in how spaces and zones are used

16
00:00:54.621 --> 00:00:55.355
through the BAT

17
00:00:56.723 --> 00:00:58.458
for the above reason,

18
00:00:58.458 --> 00:01:02.195
the submenus all include
an additional link to the floor plan

19
00:01:02.195 --> 00:01:06.699
screen, which is available in the upper
right section of the header bar.

20
00:01:08.201 --> 00:01:10.470
The user can also add a new space

21
00:01:10.470 --> 00:01:13.473
using the add space button.

22
00:01:13.706 --> 00:01:17.377
It is not always obvious
at the start of an audit assessment

23
00:01:17.544 --> 00:01:22.749
what spaces and zones will be
the most helpful to define in advance,

24
00:01:23.416 --> 00:01:28.488
and this link can be used to quickly add
or adjust these definitions

25
00:01:28.488 --> 00:01:33.393
for data collection efficiency
in real time during the walk through.

26
00:01:33.893 --> 00:01:37.797
Generally, spaces and zones are intended
to help the user define

27
00:01:37.797 --> 00:01:41.067
the spaces served by the HVAC equipment

28
00:01:41.768 --> 00:01:44.504
On some submenus,

29
00:01:44.504 --> 00:01:48.208
spaces may also be used to define
the location of the equipment.

30
00:01:48.942 --> 00:01:52.078
These fields are so marked.
All the submenus

31
00:01:52.412 --> 00:01:55.081
make extensive use of pre-populated

32
00:01:55.081 --> 00:01:58.251
dropdown lists to expedite data entry.

33
00:01:58.818 --> 00:02:01.321
These are specific to each area

34
00:02:01.321 --> 00:02:05.125
and the user should fully explore
these prior to a site visit.

35
00:02:06.059 --> 00:02:09.395
Familiarity
with the content of these dropdowns

36
00:02:09.395 --> 00:02:12.632
will greatly enhance
the user's experience with the BAT.

37
00:02:13.399 --> 00:02:16.202
In some cases,
the user may need to enter data

38
00:02:16.202 --> 00:02:19.539
into several sections
to completely characterize the system,

39
00:02:20.206 --> 00:02:25.311
such as hybrid system, which incorporates
elements from multiple systems,

40
00:02:25.478 --> 00:02:29.883
may require the user to break the data
entry into component parts.

41
00:02:30.783 --> 00:02:31.618
For example,

42
00:02:32.652 --> 00:02:34.387
central cooling system

43
00:02:34.387 --> 00:02:37.090
may require entries in the cooling plan.

44
00:02:37.090 --> 00:02:40.059
Cooling tower pumps H2

45
00:02:40.059 --> 00:02:43.563
and or terminal unit subsystems.

46
00:02:44.097 --> 00:02:47.800
Now we will break down the differences
and what is required

47
00:02:47.800 --> 00:02:51.738
of each submenu.
To get to the heating plant Submenu,

48
00:02:51.804 --> 00:02:55.208
Select the heating plant button
in the navigation pane on the left,

49
00:02:56.242 --> 00:03:00.547
Unique fields on this submenu
include type of heating plan,

50
00:03:01.014 --> 00:03:04.083
which offers the user
the option to specify

51
00:03:04.083 --> 00:03:07.487
whether the heating plan is centralized
or decentralized.

52
00:03:07.921 --> 00:03:13.193
Equipment Type. A dropdown list offers
the user all the common types

53
00:03:13.193 --> 00:03:16.796
of heating equipment typical
for central and decentralized plants.

54
00:03:18.064 --> 00:03:21.067
Heat input output readings

55
00:03:21.134 --> 00:03:25.939
which are fields provided to enter heat
input and output capacity numbers.

56
00:03:26.406 --> 00:03:30.410
Standard units are specified.
Heating fluid,

57
00:03:30.843 --> 00:03:34.480
which has steam and hot
water, are provided as options

58
00:03:34.514 --> 00:03:39.485
although other systems may be specified.
Boiler plant accessories,

59
00:03:39.953 --> 00:03:44.324
where options accessories
such as economizers and Oxygen Trim

60
00:03:44.324 --> 00:03:48.895
are provided
through the dropdown lists and controls.

61
00:03:48.895 --> 00:03:49.696
Description.

62
00:03:49.696 --> 00:03:53.132
Given that control systems vary
greatly from system to system,

63
00:03:53.533 --> 00:03:57.770
the user is provided a textbox
in which to describe the controls.

64
00:03:58.538 --> 00:04:01.774
The notes taken in
this field will appear on the audit report

65
00:04:01.774 --> 00:04:05.878
for later use. And finally, condition assessment fields.

66
00:04:06.813 --> 00:04:09.582
There are several optional condition
assessment

67
00:04:09.582 --> 00:04:13.253
fields in this submenu,
including boiler age and condition.

68
00:04:14.287 --> 00:04:20.026
Next we have the cooling plant submenu
to get to the cooling plant submenu.

69
00:04:20.159 --> 00:04:23.162
Select the button
on the left side of the navigation screen.

70
00:04:23.997 --> 00:04:29.002
This menu is like the one for
heating plants in both form and function.

71
00:04:29.535 --> 00:04:33.106
However, equipment specification
fields are customized

72
00:04:33.106 --> 00:04:36.109
to include equipment common
for chiller plants.

73
00:04:36.242 --> 00:04:41.014
Next, we have the cooling tower submenu
to get to the cooling tower Submenu.

74
00:04:41.147 --> 00:04:44.317
Select the button
on the left side of the navigation screen.

75
00:04:45.351 --> 00:04:47.520
Cooling towers are an important part

76
00:04:47.520 --> 00:04:52.792
of a variety of heating cooling systems
and a separate input menu

77
00:04:52.792 --> 00:04:55.795
is provided for use to describe their use

78
00:04:55.862 --> 00:04:58.498
at the building facility.

79
00:04:58.498 --> 00:05:01.534
The only required field
is the cooling tower type.

80
00:05:02.735 --> 00:05:04.437
Next, we have the pump

81
00:05:04.437 --> 00:05:07.473
sub menu. To get to the pump submenu,

82
00:05:08.107 --> 00:05:11.344
Select the button
on the left side of the navigation screen

83
00:05:12.011 --> 00:05:15.982
and input form is provided
to allow the user to characterize

84
00:05:15.982 --> 00:05:20.787
major pumps and the form functions
the same as those prior

85
00:05:21.587 --> 00:05:24.590
Asterisked entries are required.

86
00:05:24.891 --> 00:05:28.027
In the interest of keeping this video
as concise as possible.

87
00:05:28.561 --> 00:05:32.432
For more information on details of
the form, please refer to the user guide.

88
00:05:33.266 --> 00:05:36.102
Next, we have the piping submenu.

89
00:05:36.102 --> 00:05:38.971
To get to the piping submenu, select
the button

90
00:05:38.971 --> 00:05:41.974
on the left side of the navigation screen.

91
00:05:42.141 --> 00:05:47.246
An input form is provided to characterize
the condition and characteristics

92
00:05:47.580 --> 00:05:50.850
of important pipe assemblies
in the building or facility.

93
00:05:52.151 --> 00:05:56.522
Conceptually,
the intention of this menu is to offer

94
00:05:56.789 --> 00:06:00.493
the user the ability to characterize
potential heat losses

95
00:06:00.727 --> 00:06:05.832
from poorly insulated piping and inputs
have been designed accordingly.

96
00:06:06.332 --> 00:06:09.836
The BAT will accommodate as many entries
as are required

97
00:06:09.836 --> 00:06:12.171
to properly characterize such losses.

98
00:06:13.473 --> 00:06:16.676
A text
field is also provided to describe issues

99
00:06:16.676 --> 00:06:20.012
with the uninsulated valves
or steam traps.

100
00:06:20.346 --> 00:06:23.349
Next, we have the AHU submenu

101
00:06:23.916 --> 00:06:26.753

the air handling unit or AHU

104
00:06:33.393 --> 00:06:37.597
Input form is the longest
and most complicated form in the BAT.

105
00:06:38.398 --> 00:06:42.268
Given the wide variety of options
installed with such systems,

106
00:06:42.969 --> 00:06:46.272
an extensive list of input field
is provided.

107
00:06:46.873 --> 00:06:48.541
Fields to specify the area served

108
00:06:48.541 --> 00:06:53.045
the type of equipment, supply
fan characteristics,

109
00:06:53.546 --> 00:06:58.084
cooling and heating coil information
and controls are available for input.

110
00:06:59.485 --> 00:07:02.455
Next, we have the terminal sub menu

111
00:07:02.455 --> 00:07:04.891
to get to the terminal Sub menu.

112
00:07:04.891 --> 00:07:07.894
Select the button
on the left side of the navigation screen.

113
00:07:08.861 --> 00:07:12.632
The input form for terminal
units is used to collect data

114
00:07:12.632 --> 00:07:17.003
for a wide variety of units
as listed in the unit type dropdown.

115
00:07:18.704 --> 00:07:20.339
Non-Listed Unit types

116
00:07:20.339 --> 00:07:24.177
can be added using the other selection
and input field.

117
00:07:25.378 --> 00:07:29.482
This form also includes
data entry fields for the condensing unit.

118
00:07:29.782 --> 00:07:34.387
Terminal Unit control and heating
coil information as applicable.

119
00:07:35.254 --> 00:07:38.558
The BAS or EMS EVHS

120
00:07:38.791 --> 00:07:42.195
exhaust fan and other HP AC submenus

121
00:07:42.628 --> 00:07:45.631
all give the option to input such details

122
00:07:46.065 --> 00:07:49.802
about any relevant system
or units installed on site.

123
00:07:50.670 --> 00:07:55.875
You will notice that other HVAC is red
and therefore represents the option

124
00:07:55.875 --> 00:07:59.912
to input
FCA related information into the BAT

125
00:08:00.613 --> 00:08:03.783
Once the required information
in the selection is complete,

126
00:08:04.083 --> 00:08:07.854
you can return to the main menu
by clicking on the main audit menu.

127
00:08:07.954 --> 00:08:11.390
