Building technology producing all energy
 the building consumes solely by Solar.


A small enterprise in Sweden is active in integrating sustainable technologies for homes. It likes to call its new project "active house" as opposed to passive house, as it will produce more energy than it will consume. The surplus may be used in the hybrid car for instance.


The company has assembled a circle of interested parties with the aim of putting forward a European proposal. The plan is to offer a substitute for the integration techniques of solar panels and collectors.


The direct cost will be ½ of the current prices (of solar technology plus installation). Almost all new housing developments in Southern Europe and Spain (as and when they recover) will be using solar technologies. The proposed substitute will leave a nice margin to the developers and the owners of Active House technology.


The materials used will have much better technical features and also environmental credentials. Energy consumption will be lower than with existing demonstrators such as those from and also the surface area of solar modules. Hence the overall figure of 50% cost saving.


At a later point this technology could be well applicable to Solar Fields.


In more practical terms, the object of the current European funding bid will be to build one floating demonstrator house that can be transported to different countries.

(It does not have to float, it can stay on firm ground, but the materials used are so light it will be possible).

The main driver is to produce more energy than to consume, while maintaining a very stable indoor climate year round.


The technologies and components that the company has a permission to use in home construction include:


  • Solar powered heating and cooling, including salt as the energy storing agent, from; PV modules from

  • Lightweight roof, façade and insulation panels from that are also quite economical;

  • Importantly, solar collectors and PV cells will be attached to the composites using a very low cost proprietary technique. Installation means currently half the cost of the solar technology. One side of the house will be the “Solar side”, homogenous and waterproof  facade including all the solar installation.




  • House producing more energy than it uses.
  • Energy Effective construction
  • Recycling of air and ventilation
  • Production of heat and cooling by solar collectors
  • Production of electricity by solar cells
  • Charging of transport vehicles( EV cars, MC, Boats)
  • Water or land based buildings
  • Long Life Cycle




  • Buildings which produces more energy than they uses.
  • Cost effective installation of Solar technology.
  • Allergy- free houses .
  • Flexible architecture by land and by sea.


The partners will invest matching funding on similar terms.

The competence currently lacking is to integrate all the controls into a central panel. Secondly, building remote and wireless access into the controls will be highly desirable.

In 2002 a Russian engineer came up with an IKEA concept for sustainable housing using Dome design. In 2013 after having developed his constructions in Finland and Spain he added the technology of SolarVIsion hence now having the option to have houses that are not only neutral but actually produce more than they consume.


Cleado uses these technologies  combining the flexible Styrofoam Solar PV plates with the IKEA style Dome house construction: With 10m2 of Solar PV the house produce 110kwh AC per day while using only 20kwh AC per day hence generating a surplus which can be fed into the grid at a feeding tariff of 0.58 USD when in Japan.


The concept of CLEADO is to provide sustainable, effective living space at a competitive cost while generating a surplus of energy. CleaDo  currently have housing ready in  Japan, South Africa, Cayman Islands and Brazil. CleaDO  develops land and construct dome houses fitted with solar panels. Main areas for construction of these houses are recreational land close to mountain or beach.




Power efficient living is a big thing in most countries. In Japan after the disaster 2011 several new renewable projects are developed and in South Africa and Brazil  30% of the energy is spent on heating up water. CleaDo changes this with affordable and sustainable living.
