MOS is one of the largest and most important trade fair events in Slovenia with 1 500 exhibitors from 35 countries and more than 125 000 visitors. A new feature this year was a Crossroads of Science and Economy, supported by the Ministry of Education, Science and Sport. This special part of the exhibition promoted cutting-edge technologies and new technological innovations and processes. National Institute of Chemistry in Ljubljana was one of several scientific institutions present at the stand. The institute has developed a special kind of color painting, TISS coatings, that will improve both efficiency and aesthetics of a solar collector. The NorDan Solar concept with solar collectors integrated in traditional window frames was used to illustrate state of the art solar collector solutions.

Aventa recently visited the German research institute for solar energy - Fraunhofer ISE, in Freiburg - where our solar collectors have been a part of the experimental set-up  for several years. The solar collectors are primarily undergoing accelerated aging tests, which will determine their lifespan under various conditions. Ad hoc testing of the collectors is also being carried as part of our product development programme. 

Planning of pilot projects was on the agenda when the partners in the Nordic Built project “Active Roofs and Facades in Sustainable Renovation” met in Malmö recently. The goal is to show solutions for sustainable renovation that are possible to integrate in existing buildings with respect to both architecture, comfort and energy efficiency. The Aventa technology will be used at a demo-site at the Technological Institute near Copenhagen and most likely will also a CO2 neutral kindergarden In Copenhagen be equipped with building integrated solar collectors from Aventa.

BioSol represents a new concept for heat transfer from a stove into a water-based heating system, which combines high efficiency and negligible risks. A solar system is directly coupled to the heating system. The energy demand for space heating and hot water preparation can thereby be 100% covered by renewable energy in terms of firewood and solar energy. 

This Task aims at the purchase price reduction for end-users of installed solar thermal systems by evaluating and developing sustainable means to reduce production and/or installation costs on material, sub-component, system-component and system level. Special emphasis is placed on the identification and reduction of post-production cost drivers. Additionally, ways to make solar thermal more attractive by improved marketing and consumer-oriented design will be explored.

- a solar energy system, a green house and a fish pond are set to make the study of natural sciences more research-focused and practical.

On September 2, Molde Upper Secondary School launched its brand new roof lab, becoming Norway's very first school with an outdoor system modelled after American 'rooftop gardens'. The lab, which is specifically designed to make natural science subjects more research-focused, includes a solar energy system from Aventa, which will generate power for a range of purposes, in addition to being part of student experiments. 

Aventa invited a group of European solar experts to visit Stenbraatlia housing estate, where the Norwegian building association OBOS has built thirty-four terraced houses equipped with roof-integrated polymer solar collectors. 

“This housing estate represents the future of sustainable building projects, in which solar collectors merge with the building envelope, offering not only energetic advantages but visual appeal as well”, says Hans Dahl, the company's architect, who participated at the technical tour together with project leader Egil Wahl.

NorDan and Aventa have developed a solution for integrating solar collectors into window constructions. This summer we have installed two new NorDan Solar reference systems; one in a private home in Stavern, and the other at Otta High School Climate Lab. These systems have visually attractive combinations of windows and solar collectors in facades. 

A major objective of SCOOP is to demonstrate innovative polymer solar collectors that can meet the market requirements for heating applications in the medium and high temperature range with a service-life comparable to those of conventional products. Several reference projects will be installed during 2014 in order to show the feasibility and potential of polymer collectors, three of them with AventaSolar technology. These will be followed up with detailed documentation and a lot of publicity.
