Low Energy Building Product. Build a house in days.
Matt asked me to join to answer any question on the low energy building product he came upon through us. Feel free to ask for more info.
Below is some info that may be of interest. Before I send you any detailed info you will need to contact me via email or phone.
They are currently built in the UK, Italy, Spain, Germany, Norway & Turkey & almost everywhere in Europe in USA and Africa.
It’s a good product and can be built in from two days.
We don’t have actual movie, but assembling prefab houses is the exactly the same as this German company showing on YouTube video blow: weberhaus is not our company, we are cheaper.

4. Interior painted wooden staircase, painted by "EKO" coat paint per Customer's choice, if needed, per architectural/structural design
5. Roof construction - timber trusses and rafters, battens, PE foil for vapour barrier, OSB panel 10 mm, mineral wool if needed, per architectural/structural design (excluding roof tiling, down pipes, gutters and flashings)
6. Electrical conduits with junction boxes installed
7. For plumbing, additional thin framing with access panel where plumber contractor would be able to install fittings
*Please note the panel thickness varies depending of structural design and wind zone as per Australian Standard requirement.
Exclusions:
1. Crane for container unloading and installation of prefabricated/assembly materials
2. Water and electricity on site
3. Site preparation with finished concrete slab, ready for the assembly of the facility
4. Ancillary manpower for the assembly and construction work for the completion of the building
5. Down pipes, flashing and gutters
6. Floor finish and tiling for wet areas, painting of walls, joinery & fit-outs for kitchen, laundry and bathrooms
7. Additional thin framing with access panel where your plumber contractor would be able to install fittings
8. Façade finish and auxiliary scaffold, if required
Type of soil is not issue, since the system should be assembled on top of concrete footings/slab.
Special benefit we find in extreme climate, hot climate as well as cold, because of good insulation, double glazed windows and breakage of thermal bridges. Company paying special attention to appropriate thermal/acoustic calculation for every project.
The ship container transport should take from 6 to 8 weeks.
With the prefabricated system you are able to build in about 1/3 of the time needed to construct a site- conventional way.
Cost is from $490/m2 + $200/m2 for transport. Saving in time on construction and skilled tradesman on site. We are actually delivering much more than Lock up Stage, eg. internal doors with all accessories, ceilings and internal plasterboard linings, staircases if required, electrical junction boxes & conduits ready to connect wires, etc.
The "Star Rating" is a measure of the energy efficiency of a building (5 star is considered energy efficient).
New South Wales uses the online tool BASIX and Queensland has BERS. Using thermal calculation, a building is compliant if it does not exceed an annual energy allowance, and the energy usage of the building is given a star rating of up to ten stars. A building passing with a star rating is not obliged to match all the acceptable construction provisions of the Deemed-to-Satisfy energy efficiency provisions, as the star rating shows that the building achieves the required overall thermal performance. A thermal calculation can be produced using Accurate, FirstRate5 or BERS Professional software, which are accredited for this purpose.
Heating and cooling homes adds cost to energy bills and impacts the environment. The amount of energy needed to stay warm in winter and cool in summer can easily be reduced by the good design and construction of our homes. Assessing a building's thermal performance at design stage can identify simple, economical ways to make it more comfortable and save energy.
House energy rating through the Nationwide House Energy Rating Scheme (NatHERS) uses computer simulations to assess the potential thermal comfort of Australian homes on a scale of zero to 10 stars. The more stars, the less likely the occupants need cooling or heating to stay comfortable.
What is rated?
A dwelling can be rated before or after it is built. The rating depends on:
• the layout of the home
• the construction of its roof, walls, windows and floor
• the orientation of windows and shading to the sun's path and local breezes
• how well these suit the local climate.
Energy consumption by hot water systems, lights or household appliances is not part of the rating because those fittings are usually replaced several times during the life of the building.
What the stars mean
• Zero stars means the building shell does practically nothing to reduce the discomfort of hot or cold weather.
• A 5 star rating indicates good, but not outstanding, thermal performance.
• Occupants of a 10 star home are unlikely to need any artificial cooling or heating.
Houses built in 1990 averaged about 1 star on the NatHERS scale. Before the introduction of national energy efficiency regulations for houses in 2003, less than one per cent of Australian houses achieved 5 stars.
When you register your name & email we will provide you with full details of below.
“Standard” is our Low Energy construction, “Euro” is Passive house and “Mega” is very close to Zero Energy house.
If customer wish to achieve Zero energy house it will required thicker wall with more insulation and specific architectural design.
The U value is the number of watts that will pass through 1 square metre of a material. The U-value (or U-factor), more correctly called the overall heat transfer coefficient, describes how well a building element conducts heat. It measures the rate of heat transfer through a building element over a given area, under standardized conditions. The usual standard is at a temperature gradient of 24 °C, at 50% humidity with no wind (a smaller U-value is better).
U is the inverse of R with SI units of W/(m²K) and US units of BTU/(h °F ft²):
The R-value is a measure of thermal resistance used in the building and construction industry. Under uniform conditions it is the ratio of the temperature difference
across an insulator and the heat flux (heat flow per unit area, QA) through it or :
The R-value being discussed is the unit thermal resistance. This is used for a unit value of any particular material. It is expressed as the thickness of the material divided by the thermal conductivity. For the thermal resistance of an entire section of material, instead of the unit resistance, divide the unit thermal resistance by the area of the material. For example, if you have the unit thermal resistance of a wall, divide by the cross-sectional area of the depth of the wall to compute the thermal resistance. The unit thermal conductance of a material is denoted as C and is the reciprocal of the unit thermal resistance. This can also be called the unit surface conductance and denoted by h. The bigger the number, the better the building insulation's effectiveness. R-value is the reciprocal of U-value.
R-value should not be confused with the intrinsic property of thermal resistivity and its inverse, thermal conductivity. The SI unit of thermal resistivity is K•m/W. Thermal conductivity assumes that the heat transfer of the material is linearly related to its thickness. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added:
R-value(outside air film) + R-value(brick) + R-value(sheathing) + R-value(insulation) + R-value(plasterboard) + R-value(inside air film) = R-value(total)
For Auset Pacific system R-value is:
External Wall Insulation Rating (R value) = 6.75 R
Ceiling And Roof Insulation Rating (R value) = 7.51 R
Windows and Doors Insulation Rating (R value) = 1.10 R
To conclude, houses built with our system, with proper architectural layout and design are Low Energy Houses with Energy Rating 6+.
