Specifications

Having a checklist comes in handy when designing complex jobs. Seresco is pleased to
provide this natatorium design checklist for your convenience. We also provide our
complete Natatorium Design Guide online, along with extensive specification and design
resources, including load calculation software.

1. Operating conditions in writing from end user (pool
water temperature, room air temperature)
2. System supply CFM delivers 4-6 air changes per
hour. The room volume dictates the supply CFM.
Supply air gets to the ‘breathing zone’
Good overall air pattern covering the entire space
No short circuiting
3. Outdoor air CFM per Standard 62
Baseline: 0.48 CFM/ft² of water and deck for regu-
lar pool
Add 7.5 CFM per spectator (swimmers are not
considered spectators and are covered in the
baseline OA CFM)
4. Exhaust Air
Room is at slight negative pressure (0.05 to 0.15
inches of water column)
110% the outdoor air CFM is generally
recommended
Source capture contaminants – Exhaust air drawn
from the whirlpool or any other warm or highly
active water area
5. Load Calculation
Latent load (pools, OA and spectators)
Sensible cooling load has been calculated for the
space design temperature
Heating load has been calculated for the space
design temperature and includes OA
6. Condensation and Vapor Migration
Vapor barrier on the warm side of the dew point
temperature in all walls, ceiling and floors
All exterior windows, doors and skylights are fully
blanketed with supply air (3-5 cfm per sq ft)
7. Energy & LEEDs Considerations
Energy Standard 90.1 – pool water heating option
Heat recovery between the minimum OA and
minimum EA
Condensate reclaim
System refrigerant charge reduction –
Protocol Design
8. Swim Meet Mode
Number of spectators and competitors expected?
Spectator areas
Spectator Area has 6-8 Air Changes per hour of
supply air
Airflow to spectator seating areas
Micro climate via separate air handler for larger
spectator areas
9. Service and Maintenance
Internet monitoring
Unit is accessible
Unit has adequate service clearance
* Please contact factory for waterparks and pools with ad-
ditional recreational water features. Design standards have
been established for ‘traditional’ bodies of water and do not
adequately address the special needs of these facilities.
