EVAPORATION IS CONSTANT HEAT LOSS & HUMIDITY GAIN -
Because all indoor pools are heated year round, evaporative cooling causes heat loss and vapor-saturated air inside the building structure. Because indoor pools require high levels of ventilation, fresh make-up air comes in one side, heated exhaust air goes out the other. Dehumidifiers work 24x7x365 to keep up with humidity generated by the pool. Indoor air quality, chloramines, and corrosion are an integral part of this big evaporation equation. Evaporation rates and energy consumption increase (50% - 70% of the daily total) during 8 hours at night due to uncovered warm pools and colder nights.
- Traditional natatoriums crank up their dehumidifiers (and electrical consumption) at night (lower temperatures) to overcome increased humidity and heat loss created by increased evaporation. Pools are the source of the humidity, greater evaporation translates into greater heat loss. Meaning dehumidifiers operate at peak capacity when no people are in the building.
- Innovative natatorium operations can now create a big financial splash by changing simple procedures. Covering warm water surfaces at night with a vapor impermeable membrane captures huge amounts of heat naturally lost to evaporation. This procedure retains existing heat in the water, essentially using the pools as large energy storage vessels. This dramatically reduces dehumidification requirements and costs too. Energy efficiency is achieved by stopping pool evaporation, the root cause of huge heat loss and humidity gain. Save HVAC, save energy, use blankets.
- Energy flow is cash flow - add up your gas, electric, water, and chemical bills for each year. Put the past 5 years on spreadsheets to accurately track therms, kilowatt hours, total delivered energy costs, gallons, degree days, all the details. Now factor in 50% efficiency improvement. What's the real impact on your operating budget? Project that 10 years to fully grasp financial and environmental implications.
USER-GENERATED INNOVATION
Dynamo launched an Energy Conservation Project in 2003, investing in solar hot water heating systems and pool blankets.
With 5 big indoor pools, energy savings averaged $237,000 per year for 4 years. A 6th pool built in 2008 changed the baseline comparisons, but projected annual savings now approach $300,000. Volatile natural gas prices plummeted in 2009 to new 7-year lows, but offsetting electricity and water rates are still increasing. The most important finding? Dynamo discovered surprisingly bigger performance in energy efficiency of blankets vs. solar free heat, documenting 5-year
cumulative savings over $1.2 million. Dynamo/Chamblee - 50mtr x 25yd competition pool
"Whole Pool" = one blanket (12,300 sq.ft.) A very innovative new blanket
and automation system has evolved from this energy efficiency project. Shown above is the "whole-pool" membrane, a single lightweight blanket covering a 50mtr x 25yd pool. This novel method has created honest-to-goodness productivity, made it faster and easier, fundamentally changing handling time and labor. The solution is all about speed, ease, efficiency, reliability, coverage integrity, and life-guard acceptance. Read more about Dynamo Swim Club's groundbreaking
Energy Conservation Project here.
HANDLING TIME & LABOR - If you think blankets are time-consuming and hard to use, keep reading. We have a solution for those two problems, you'll be impressed....
THE SYSTEM enables one life-guard to easily apply and remove one "whole-pool membrane" covering any sized pool. The automated model takes only 30 seconds for 25-yard pools, only 60 seconds for 50-meter pools. Solving time and labor issues is the primary objective. True handling ease will deliver incredible productivity and user acceptance. The goal is to achieve big energy & water & economic savings for you.
Both manual and automatic H2O Energy Blanket models provide fast & easy "furling" system options.
CONVENIENCE -Foremost, it is fast & easy. On-deck, above-deck, or innovative under-deck installations. Even bench & bleacher functionality. Consider truss-mounted wall systems at any height or ceiling installations. Each custom engineered for maximum safety, integrity, durability, speed.

ARCHITECTS / AQUATIC DESIGNERS / POOL OPERATORS -
Take note of Energy Code requirements. Deliver operating performance year round with green, clean, easy, substantial energy efficiency technology. Deploying a vapor barrier membrane physically stops evaporative cooling, heat loss, and humidity gain at the primary source, the open pool. Give those dehumidifiers a rest. Do the math, well over half of total gas-electricity-water consumption and operating costs occur at night - between 10 PM and 5 AM when outdoor temperature differentials are greater and the pool is unused.

AQUASYNTHETICS - H2O Energy Blankets are lightweight engineered fabrics that perform in water, hydrophobic, chemical resistant, mold & mildew resistant, high durability, abrasion resistant, high vapor barrier technology that stops 97% of heat loss due to evaporation, ventilation, and dehumidification - without worrying about problems with chloramines, organic & inorganic compounds, ammonia, body oils, air flow, indoor air quality, corrosion, and water balance. These unusual high performance fabrics spend their life in the water, every day year round. "Aquasynthetics" is a fitting description.
"ENERGY BLANKET" - Energy blankets, fabricated with aquasynthetics, put a lid on warm pool water. The warmer the water, the cooler the outside air, the lower the relative humidity, the greater the rate of evaporation. All natatorium pools are heated, all nighttime temperatures go down, and all evaporation rates go up at night. A vapor barrier blanket will virtually stop surface water evaporation, a phenomenon known as evaporative cooling. Evaporation is the cause of the vast majority of heat loss and humidity gain. Blankets significantly reduce a natatorium's year round energy and water consumption, humidity, corrosion, emissions, interior air quality problems - and operating costs.
CUT HVAC - DEHUMIDIFICATION OPERATING COSTS
LEADERSHIP IN ENERGY EFFICIENCY & WATER CONSERVATION "Best Practices" should be the foundation of natatorium operations. Financially, operationally, and environmentally, the huge implications for natatoriums to demonstrate energy & water leadership examples for sports, recreation, aquatics, fitness, wellness, municipalities, educational institutions, and industry warrant a closer look.
Energy & water are the pillars of clean energy infrastructure and healthy environmental values for commercial indoor pool owners. Covering continuously heated pool surface water at night yields a significantly greater cost savings impact year round than any other equipment replacement, procedure, or operating practice possible in natatoriums.
COMMON SENSE - When a pool is NOT being used 7-8+ hours at night, isn't it oxymoronic and incongruous to keep the dehumidifiers cranked up in order to keep pace with evaporation, heat loss, and humidity from its very SOURCE = THE POOL?
PURE PHYSICS - Especially when a vapor membrane covering the water surface physically stops evaporation - which stops humidity and stops heat loss. It stops evaporation at relatively no operating cost vs. powering dehumidifiers at really big cost. This does not mean turning off dehumidiifers, it means simply stopping the liquid-to-gas transformation (evaporative cooling process). Why should dehumidifiers churn so hard all night consuming so much electricity necessary to overcome the unrelenting higher rate & volume of evaporation? When an energy blanket stops the evaporative process.
Retain heat energy in your pool, improve air quality, keep your money from evaporating, make a big contribution to climate conservation, feel much better.
GOT GREEN? Commercial natatoriums cannot achieve such significant financial and environmental results anywhere else in their operations.
This is a great leap forward for indoor swimming pool "best practices." The rising green consciousness drives smart management with results.
DOUBLY GREEN? Not only environmentally smart choices, but real operational efficiencies equates to finding "greenbacks." A typical 50-meter pool can conserve over $100,000 per year using energy blankets. What impact does that have on your operating budget?
