3.9.5 Swimming Pools

Configuration and Design Requirements

Pool Name

Applicability

All pools

Definition

A unique identifier that keys the pool to the construction documents

Units

Text, unique

Input Restrictions

None

Baseline Rules

The name for the baseline building pool should be similar to the proposed design.

 

Volume

Applicability

All pools

Definition

The volume of the pool

Units

Cubic feet (ft³)

Input Restrictions

None

Baseline Rules

Same as the proposed design

 

Surface Area

Applicability

All pools

Definition

The surface area of the pool affects heat loss and evaporation.

Units

Square feet (ft²)

Input Restrictions

None

Baseline Rules

Same as the proposed design

 

Cover

Applicability

All pools

Definition

An indication

Units

Boolean (Yes/No)

Input Restrictions

None

Baseline Rules

The baseline building shall have a pool cover per Section 7.4.5.2 of ASHRAE Standard 90.1-2007.

 

Cover Schedule

Applicability

All pools

Definition

A schedule indicating when the pool cover is in place

Units

Data structure: schedule, on/off or fractional

Input Restrictions

None

Baseline Rules

Same as the proposed design

 

Filtration Rate

Applicability

All pools

Definition

The rate at which the pool water is passed through the filtering system when the filtration system is operating

Units

Hours per pool change

Input Restrictions

None

Baseline Rules

Same as the proposed design

 

Filtration Schedule

Applicability

All pools

Definition

A schedule indicating when the pool filtration system is in operation

Units

Data structure: schedule, on/off or fractional

Input Restrictions

None

Baseline Rules

Same as the proposed design

 

Temperature

Applicability

All poolsact

Definition

The temperature at which the pool is maintained

Units

Degrees Fahrenheit (°F)

Input Restrictions

None

Baseline Rules

Same as the proposed design

 

Temperature Schedule

Applicability

All pools

Definition

A schedule indicating variation in the pool temperature, either seasonally or monthly

Units

Data structure: schedule, temperature

Input Restrictions

None

Baseline Rules

Same as the proposed design

Pumping and Filtration

Pumping Power

Applicability

All pools

Definition

The power used by the pumping system. This is a function of the pumping head (which depends on pipe lengths, sizes, and filtration type), the pump efficiency, the motor efficiency, and the flow rate. Some software may allow these to be entered as separate building descriptors. This value should be consistent with the filtration rate noted above.

Units

Watts (W)

Input Restrictions

None

Baseline Rules

Same as the proposed design unless the proposed design uses special low head filters and premium efficiency motors

Heating Equipment

Heater Type

Applicability

All pools

Definition

The type of equipment that is used to maintain the pool temperature

Units

List: solar, heat pump, gas, oil, or electric resistance

Input Restrictions

None

Baseline Rules

If there is gas or oil on the site, the baseline building shall be modeled with a natural gas or oil pool heater meeting the requirements of Table 7.8 for ASHRAE Standard 90.1-2007. If there is no gas or oil on the site, the baseline building shall be modeled with a heat pump pool heater meeting the requirements of Table 7.8 for ASHRAE Standard 90.1-2007.

 

Heater Efficiency

Applicability

All pools with heaters

Definition

The thermal efficiency of the pool heater

Units

Unitless, thermal efficiency

Input Restrictions

None

Baseline Rules

See the baseline building rules for heater type

 

Solar System Features

Applicability

All pools with solar pool heaters

Definition

The collector area, size, efficiency, and pumping characteristics of the solar pool system

Units

Data structure

Input Restrictions

None

Baseline Rules

Not applicable. The baseline building has a pool cover, not solar
