Innovation in energy, environmental, ergonomic, and economic operations strictly for natatoriums
While alternative energy and subsidies grab headlines elsewhere, H2O Blankets yield substantially greater energy efficiency, water conservation, and real environmental values for natatoriums. No grants, subsidies, incentives, or artificial support necessary for financial justifiction. Stands on its own strong, continuous merits.
Combining pure physics and pool operating logic - stopping warm water evaporation at night stops heat loss, stops humidity gain, dramatically reduces energy consumption. Think sustainability and environmental impact, then think about huge ongoing financial benefits for operating budgets:
~ SERIOUS GREEN ~
• 50% energy conservation
• 50% water conservation
• 50% GHG emissions reduction
• 50% dehumidifier/HVAC demand reduction
BY ANY MEASURE THIS IS CONSIDERED
~ EXTRAORDINARY ENERGY EFFICIENCY ~
NATATORIUMS ARE UNIQUE BUILDINGS
DO SOMETHING ABOUT IT: It's not just about being very green and sustainable. It's about operationally making big differences. Cutting annual utilities costs by 50% is serious money for big pools.
IT'S ABOUT STOPPING EVAPORATION:
Bottom line savings for one typical
50-meter indoor pool using an
energy blanket 8 hours nightly
can exceed $100,000 every year.
SERIOUSLY...
WHY WOULD ANY COMMERCIAL POOL NOT USE ENERGY BLANKETS?
We invite you to explore the facts
about why and how such enormous
energy and water conservation
opportunities are now so
practical, fast, and easy
for big indoor pools
INNOVATION FOR: THE PROCESS OF EVAPORATION
Stopping evaporation (enthalpy = heat loss) physically, not mechanically dehumidifiying vapor out of air with HVAC
INNOVATION FOR: NATATORIUM ENERGY CONTROL
The only way to achieve such big energy and water efficiency is stopping indoor pool evaporation at night.
INNOVATION FOR: PRODUCTIVITY & OPERATING COST Efficiency cuts consumption in half. Productivity improves handling time & labor 50-fold on 50-meter & 25-yard pools.
In this emerging energy efficiency age where responsible businesses demand investment paybacks in 3-4 years, and most municipal and state governments are amortizing energy retrofits in the 10-20 year range -- we are different:
BIG RESULTS = H2OB systems generally average 6-9 month paybacks, cut annual natatorium utility costs by 50%, and derive an ROI in the 1500%-2000% range.
PURE RESULTS = energy conservation, water conservation, emissions reduction, handling ergonomics, financial wisdom

INFRASTRUCTURE
BY STOPPING EVAPORATION
EVAPORATION IS 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 have dehumidifier-air conditioning-ventilation mechanical systems operating 24/7/365 to battle evaporation, humidity, and chloramines. 70% of energy consumption year round generally occurs at night as lower temperatures accelerate evaporation rates. This energy and money is being unnecessarily lost.
- Complementing HVAC - stopping evaporation physically by covering the pool, rather than using mechanical system energy to combat evaporation (heat loss & humidity gain). Since 70% of daily total energy occurs at night, energy blankets reduce this part by about 85%.
- Innovative natatoriums can create a big financial splash by covering pools every night to stop evaporation, stop humidity, stop heat loss, dramatically reducing HVAC & dehumidification requirements. Run your numbers, they are huge.
- Energy flow is cash flow - Track your yearly gas, electric, water, and chemical bills. Using pool energy blankets can cut that major operating expense in half. Project that 10-20 years to fully grasp the 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. Dynamo discovered much greater savings performance in energy efficiency of blankets vs. solar free heat, documenting 6-year
cumulative savings over $1.5 million. Simply covering pools at night.

Consider giving high cost pool mechanical dehumidifier and A/C systems a rest - they consume over twice as much energy in 8 idle hours every night versus during 16 hours normal activity every day. Do the math, understand the physics - due to evaporation, up to 70% of total gas-electricity-water-chemical consumption and costs occur at night - from 10:00 PM to 6:00 AM when outdoor temperatures are lower & evaporation rates and volume higher.
RETHINK THIS - Over twice the energy load is concentrated in only one third of the average day. Forget traditional total daily average calculations, look at it hourly, night makes the difference HUGE.
Dehumidifier total daily energy demand (cost) occurs during those 8 nighttime hours because temperature differentials are greatest and evaporation rates highest. Air conditioning lowers the evaporation rate, but the heat and humidity come mostly from heated pool water evaporation, not outdoor air. Conclusion: 70% of energy & water consumption occurs in 33% of each day. When pools are closed.
Blankets typically reduce dehumidifer nightly run-time by 85% and total daily costs by 50%. ASHRAE calculations determine average daily energy. Re-evaluate energy demand in pools hourly, then consider what huge performance blankets can deliver at night.
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 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.
REDUCE HVAC-DEHUMIDIFICATION OPERATING COSTS
physically stopping higher nighttime evaporation rates, meaning reduced ventilation and dehumidification demand
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.
Not only environmentally smart choices, but true operational efficiencies. A typical 50-meter pool can conserve over $100,000 every year using energy blankets. What impact does that have on your operating budget?
