The
Water Summary Report contains three main parts:
Average
Rainfall Graph
Average
Amount of Water Table
Water
Source Summary Table
Average Rainfall Graph
Average Rainfall
The
monthly bar graph displays the amount of average rainfall each month that
is included with the weather file that was selected for the simulation.
Average Amount of Water Table
Average Rainfall
The
monthly average rainfall totals in inches (cm) displayed in a table.
Average Amount of Water
Volume of water based on the average
rainfall.
Water Source Summary Table
A table that displays the 'water balance' sheet for the project. It
contains the amount collected, the amount stored, the amount used and
the overall water end use.
EnergyPlus has a set of different objects related to water. Some
of these objects are required to be part of the Simergy model for the
Water Source Summary table to be generated. The EnergyPlus objects
include:
- WaterUse:Connection - a
subsystem that groups together multiple WaterUse:Equipment components.
- WaterUse:RainCollector
- The WaterUse:RainCollector
object is used for harvesting rainwater falling on building surfaces.
The rainwater is sent to a WaterUse:Storage object. In order to use
this object it is necessary to also include a Site:Precipitation object
to describe the rates of rainfall.
- WaterUse:Well
- for simulating
on-site water supply from a well. Well water is pumped out of the
ground and into a WaterUse:Storage. The operation of the ground water
well is controlled by the associated WaterUse:Storage which is assumed
to be operated as a vented cistern with no pressure tank.
- WaterUse: Equipment - The
WaterUse:Equipment
object is a generalized object for simulating all water end uses.
Hot and cold water uses are included, as well as controlled mixing
of hot and cold water at the tap. The WaterUse:Equipment
object can be used stand-alone, or coupled into a plant loop using
the WaterUse:Connections object. The WaterUse:Connections object allows
water uses to be linked to WaterUse:Storage
objects to store and draw reclaimed water. The WaterUse:Connections
object can also simulate drainwater heat recovery.
- WaterUse:Storage - The WaterUse:Storage
object is a central component
for complex water systems. This object is not needed if the only use
of water is directly from the mains, or utility service water. If
the building model is to include any on-site collection or wells or
storing and reuse of graywater, then a WaterUse:Storage is needed.
Each WaterUse:Storage can serve as a central node and make connections
to numerous sources of supply or numerous components with demand.
If a maximum capacity is not specified, the tank is assumed to have
unlimited capacity.
Rainwater Collection
The amount of rainwater harvested that falls on building surfaces.
Condensate Collection
Volume of water that is collected
from condensate water
Groundwater Well
Volume of water that is collected
from groundwater
Total On Site Water Sources
all of the above
Initial Storage
Volume of water stored at the
beginning of the simulation period
Final Storage
Volume of water stored at the
end of the simulation period
Change in Storage
Change between the initial and
final water
Water Supplied by Utility
Total On Site, Change in Storage,
and Utility Water Sources
Total Water End Uses
