THE STRUCTURE
It is constructed in the shape of a three-centred curve, with the section at the side edges beginning with a l.000 meter vertical upright from the ground up and then forming into a gentle curve, which gives a free passage of 1.800 meters at .400 meters from the inside of its base, for a maximum utilization of space.
The side panels open vertically on both sides between each pair of arches and slide up into the roof at a height of about 2.000 meters along the total length, whether it is of fixed or of mobile design. The structure is manufactured according to the Arqualand® world patented system No. 0666370B1.
These panels are made of compact transparent polycarbonate 3mm in thickness, and are equipped with an inside handle and a blocking security system preventing them from falling unexpectedly to the ground, and from being opened from the outside.
The roof panels are made in double, triple, or quadruple wall thickness in alveolus translucent polycarbonate, which are inserted into the profiles of the vaulted arches. They will not expand in any way and are not fixed by joints or welts.
Thickness of wall is dependant of size of structure. The perfect rigidity of our vaults is ensured by our tie bar profile, which goes right through the heart of the vaulted arched profile. These tie bars, which also help to maintain the right distance between each arch, are positioned under the roof to be more aerodynamic and to minimize snow or other stagnation.
All our basic profiles of fixed vaults are anodized to resist sea or chlorinated – water (to 20 microns). The foundations (by others) are in concrete, completely level, resistant and finished. All the screws and bolts will be in “marine grade 3116” stainless steel.
All the aluminium is hot-lacquered with polyester powder. Standard colour range RAL white 9010, green 6005, brown 8014. Custom made colours are also available.
THE END SECTIONS
We use compact clear or translucent polycarbonate of 4mm thickness in the lower sections and clear or translucent polycarbonate in the upper sections. The clear polycarbonate is fixed between the lacquered aluminium uprights at a distance of about 1 meter apart. There are two safety doors on each end section.
STRUCTURAL ANALYSIS
The ruin of the system happens if in any place the stress exceeds the material yield stress.We take as assumption that the structural features are preserved during the assembly, and that the excess stresses related to the assembly procedure remain under the yield stress, and are very localised for all the components of the structure.
During use, the loads to be taken into account are:
- Continued loads: structure weight
- Test or use load: nil for this type of construction
- Climate loads:
- Snow load
- Wind load
- Thermo mechanical dilation (not taken into account in this note)
For calculations in normal use, weighting co-efficient raise the loads applied together to the structure:
- Permanent loads x 1.5
- Normal snow and wind loads applied simultaneously x 1.6
- Normal wind or snow loads x 1.7
- Thermo mechanical effects x 1.5
For calculations in extreme conditions of use, weighting co-efficient raise the loads applied together to the structure:
- (permanent loads + extreme snow load + extreme wind load + thermo-mechanical effects) x 1.1
When the accidental load (constant in each geographical area) exceeds the extreme load, which depends on altitude, the structure is checked with the accidental load.
The mechanical characteristics that have not to be exceeded are:
- Yield stress to 0.2% of lengthening (Re) for compression and tensile stresses.
- 0.6 x Re for shear stresses. It is advisable to check the combinations of most unfavourable loading cases for the structure
SNOW LOAD
| Pa | ZONES | |||||
| 1A | 1B | 2A | 2B | 3 | 4 | |
| Normal load Pn0 | 350 | 350 | 450 | 450 | 550 | 800 |
| Extreme load Pn0 | 600 | 600 | 750 | 750 | 900 | 1300 |
| Accidental load | 800 | 800 | 1080 | 1080 | 1440 | |
TABLE 1– Snow load according to NV65 April 2000 standard up to 200m of altitude. These values are not always valid for some overseas depths. The load of snow is at maximum in zone 4. The normal and extreme loads of snow increase with altitude. The maximum values at 2000m of altitude are respectively 560 and 930.3 da N/m².
When the slope of part of the roof is higher than 25°, the loading is there reduced of 2% per additional steepness: 3 angles, 5 angles with facets, for frontage 1 angle, for frontage 2 angles with facets shelters: no reduction. 5 angles, 7 angles, for frontage 2 angles, for frontage 3 angles shelters: reduction of 46% on the 48° tilted side faces. 1 angle curved, 3 angles curved, for frontage curved and for frontage 1 angle curved shelters: on the curved part, between 25°and 75° of slope, the load passes form 100% to 0%.
When altitude is lower than 500m, as the slopes of the roof are free from obstacles we consider that there is no phenomenon of snow drift on the edges of the roof. The snow load is distributed uniformly on the roof. When altitude is higher than 500m, in order to systematize the calculations, we keep the snow load uniformly distributed on the roof. We thus do not treat the case of distribution of the snow which discharges the centre of the roof to overload the edges, which loads less the structure of the various types of shelters than the same load uniformly distributed (there is never pillar in the centre of the structure to support the load).
Considering the type of calculations carried out in this note, consisting in looking for the snow and wind maximum loads the shelters can support, we cannot simultaneously apply the effect of the wind and the effect of the snow. The realization of abacusues would ask indeed for a too significant number of calculations. Moreover by taking account of the two simultaneous effects, the load of snow must be half reduced. However, calculations of a standard 3 angles shelter carried out in the note 1501-NT-S410-ed 1, shows that snow and wind do not load the same elements of the structure. Thus separated calculations, taking he non reduced load of snow into account (for a given zone and an altitude) are over-estimating.

TABLE 2 – Basic dynamic wind pressure to 10m above the ground according to NV65 April 2000 standard up to 1000m of maximum altitude. These values are not valid for the overseas departments. The loads with normal wind and the loads with extreme wind are in ratio of 1.75. The pressure of wind is maximum in zone 4. It corresponds to a wind of:
- 137.9km/h in the normal case
- 182.5km/h in the extreme case
The dynamic effects of the wind are not taken into account in these calculations. We only consider the static effects.
We don’t check in this note the holding of the shelters to drive and inversion.
The normal and extreme dynamic pressures are modified by the height above ground-level (height between the top of the structure and its base):
- For heights higher than 10m, the pressures are raised.
- For heights lower than 10m, the pressures are reduced (except near the littoral, case which is not taken into account in this note).
Foot-note: Particular case when the shelter is located just at the top of a slope higher than 30% (slope, cliff), the height of the shelter taken into account is the height between, the top of the structure and the bottom of the slope. This particular case, which amplifies the normal and extreme dynamic pressures more, is not taken into account in this note.
The values of dynamic pressure correspond to a normal site. When the site is exposed, it is necessary to take account of a multiplying co-efficient whose value depends on the zone.
| SITE EFFECT | EXPOSED SITE |
| Zone 1 | 1.35 |
| Zone 2 | 1.3 |
| Zone 3 | 1.25 |
| Zone 4 | 1.2 |
TABLE 3 – Exposed site co-efficient
As we seek an over-estimating general dimensioning, we consider that there is no mask effect and we will not take any reduction co-efficient into account.
To take account of the effects:
- Of geometry (dimensions, proportions)
- Of permeability of the walls
We use the software ACORD-BAT v3.5.7 developed by the company ITECK (www.itech-soft.com) in order to determine the inner and outer walls action co-efficiets on the faces alee or against the wind according to standard NV65 (these co-efficients depend only on the geometry of the shelter).
The dynamic pressure multiplied by these co-efficients gives the loads to be applied on the surfaces of the shelter.
The permeability of the walls is taken by assumption lower than 5% because between the elements of the shelter, there are joints ensuring a relatively good sealing to the wind.
There are 4 cases of action co-efficients to be taken into account:
- Interior volume in overpressure or depression
- Wind on side or on frontage.
THERMAL RATINGS AND CLIMATE MANAGEMENT
Polycarbonate has a k2.7 value of 2.7 watt/m°²C
Light transmission:Polycarbonate has 74% ASTM D1003
Altuglas transparent for end panels: 92%
Glass tempered: 90%
Generally speaking, water temperature of the pool increases with closed enclosure about 8 to 10°C with standard covers. We can reduce that by changing polycarbonate roof (bronze or white).
Inside enclosure, with sunny weather, if it is cold outside 5°C, it is nice inside enclosure: 20°.C
Inside enclosure, with very sunny weather, if it is very hot 35°C, it is very hot inside enclosure: 50°C or more 55°C (you must open either doors or enclosure) to create cross ventilation. Alternately you can use a mechanical ventilation or dehumidifier or reverse cycle air-conditioning (however, these are not included in the quotation).
Humidity and Condensation
On high enclosures there is a small lock to block the door with a gap 10cm so that the air can enter the enclosure and reduce condensation to create a cross ventilation.
Standard dehumidifiers work but they have to be in accordance with the volume of the enclosure. Furthermore, these engines have to be placed front and rear of the enclosure, because of the length of the enclosure. This is really uncommon to have this device inside swimming pool enclosures, except for public. We recommend for you to contact our supplier for an appraisal to make sure than the unit is very effective.
ACOUSTICS AND SOUND The problem of the sound comes mainly from the heavy rain, or strong winds. Concerning people, yes it is noisy, but it has never been mentioned as a problem (this is certainly due to the fact that we increase of the height of large enclosure). A nice set of tall indoor plants or trees can help reduce noise, as well as creating a beautiful environment.
CHLORINE With enclosure you can more or less, depending of the use of the pool, divide by 2 the chlorine rate inside pool. As a consequence, Chlorine is not a problem inside the air, except for raw material that must be very salty resistant: aluminium with painting qualicoat (marine: like for boats). Stainless steel: 316L, screws A4. However due to the fact that you have an indoor swimming pool, you can fit a pure water sanitization with no chlorine odour, this is not very inexpensive and very effective.
FIRE RATING Polycarbonate is M1: O.K. for public.
Glass is MO: O.K. for public.
Alutglas is M4: not allowed for public.

DIFFERENT TYPE OF POLYCARBONATE We mainly work with transparent 10mm to 20mm 95% UV protected polycarbonate. Sometimes, my enclosure for example, we use bronze polycarbonate 10mm: light transmission is about 60%, so it becomes less hot inside enclosure. Furthermore there is less light inside the covered pool so, it is more comfortable on sunny days. We can reduce the light transmission thanks to opal polycarbonate: 45%. Warranty by General Electric – World No.1 in Polycarbonate. (Conditions will apply)
FOOTING FOR NEW WORK Our price does not include the supply and installation, footing (by other). The builder will have to contact EcoDomes to get the right size footing in relation to the size of the EcoDome. Please note that the footing will have to be certified by the builders engineer before EcoDome begins the erection of the enclosure. Footing has to be 10mm (+ - ) tolerance. Finish of the exposed footing (by other). Builder to supply storm water point every 5metres for water evacuation on the outside perimeter of the enclosure. However, a 100mm conventional existing concrete slab can receive our enclosure (domestic). INSTALLATION AND COST SAVING EcoDomes, being an extremely high technically-advanced product and precise up to (+ --) 1mm, when delivered, can be assembled 300% quicker than a conventional construction. As the old saying goes “Time is Money”. This means that the final cost of a full project will be 30% to 35% less than a conventional construction. A domestic EcoDome enclosure will take one to two weeks on an existing slab. A commercial EcoDome will take 2-3 months on an existing slab. This is apposed to 12mths to 16mths with a conventional construction.
INSTALLATION BY PROFESSIONALEcodomes supply and guarantee quality of product to your door steps. After delivery to site, the installation is done by another company who are highly trained by their French counterpart. They also are a licensed builder No. 193230C and carry the full responsibility under the Australian regulations. You also have the option to install it yourself or use your preferred builder.

SAFETY
The track for telescopic buildings are rounded and are protected when open with smooth plastic shealths. Side windows and doors can be locked. Moveable sections are secured to th rails guaranteeing their safety in high winds.
Although a haven of pleasure for relaxation, a pool also requires constant maintenance with such tedious chores as the clean-up and removal of leaves, dust, insects, small animals of sorts, etc. One could very well do without all that! Not only does ABRISUD protect your pool against such types of natural pollution, but it also increases water quality and greatly reduces pool up-keep.
End result: Your water is cleaner, virtually effortless and care-free – and thus pool pleasure once again comes to the forefront!
A simple wish finally becomes reality: A pool need not be emptied of its water in winter. Protected by an Ecodomes enclosure, water no longer gets filled with leaves and dirt. Additionally, the structure resists to cold and unfavorable weather conditions. Much in the manner of a cocoon, an Ecodomes enclosure protects your pool in winter. You can forget about your swimming pool until springtime!
Your pool is virtually enveloped during the winter months. Ecodomes thus equips your pool in the best possible way to get through this time of year, easily and simply.
All of our enclosures meet the safety requirements as stipulated by Australian law. The acquisition of an Ecodomes enclosure frees you of all other compliance measures. Nonetheless, nothing replaces the watchfulness of an adult in the pool area.
Our complete product range complies with the NF P 90-309 quality standard. In order to fulfill these requirements, our units had to successfully undergo stringent wind and snow load tests.
Our enclosures were subjected to winds from different angles of up to 120 km/hr. over a 2-day period. They can also withstand snow loads of up to 60 kg/m2. These results, of course, imply that the units were in closed (covered) position and that all anchoring devices were securely fastened.
