ZeroEdition conducted its first successful 3D modeling course.
ZeroEdition 3D modelling course at Ewers was completed by 13 students. All the registrants passed the course and have learned the basics structure of the IDA ICE software and can independently perform 3D modeling with that software using 2D planning data.
The course atmosphere and feedback was extremely positive and all the participants were and are very motivated. ZeroEdition is very happy to support their interest and meet the market demand as Estonia needs more 3D modellers due to the requirement of exchanging the current energy systems into a modern ones.

Zero Edition is a new member of the Association for Building Simulation.
Since March 2025, Zero Edition has been an official member of the Swiss Association for Building Simulation. The association brings together experts from planning, research, education and technology who are involved in dynamic building simulation – as a tool for better planning, informed decision-making and more sustainable construction practices.
The association is committed to strengthening the quality, relevance, and usage scope of simulations in the construction industry. Simulations are increasingly being used in Switzerland and offer the possibility of creating energy-efficient and low-emission buildings. Simulations also reduce investment and operating costs through optimized design of construction and technology.
"We are an interdisciplinary network for everyone interested in or using building simulation. Our members work in various fields of construction, research and education," the association's website states.
Zero Edition brings sound practical experience to the network and, together with the other members, is committed to deepening knowledge about building simulation, promoting professional exchange and further establishing the method in planning practice.

ZERO EDITION ESTONIA kicks off with the first lecture of its intensive adult training course at the Võru County Education and Technology Center EWERS with 14 participants.
Zero Edition is extremely happy to take the knowledge of 3D modelling and building simulations to this part of Estonia and Europe. We will guide the students through this course and explain future energy efficiency education options in Estonia for the ones excited to continue in this field and become a part of making this world a more sustainable place to live in with the help of simulation programs that allow us to assess exact energy needs of specific locations and at requirements for buildings in those locations.
This 3D modelling course offers a unique opportunity to get acquainted with the IDA ICE (Indoor Climate and Energy) software. The course will take place March 4 - 25, Tuesday and Thursday evenings at the EWERS computer lab. The training will be conducted by young and inspiring Richard Wallner who has been using the program for years at an expert level.

Austrian standards confirm:
Dynamic building simulations help to save costs
An analysis by Franz Vogl (infinite anergy solutions) shows that, according to Austrian standards, dynamic building simulations are expressly permitted for both: the preparation of energy certificates and the design of heating and cooling systems.
OIB Guideline 6 and ÖN B 8110-6 classify dynamic methods as the most accurate calculation method. They thus provide a reliable basis for energy assessments and technical designs.

ZeroEdition and EWERS create an opportunity to learn innovative energy simulation software
On February 5, Võrumaa Education and Technology Center and Zeroedition OÜ signed a cooperation agreement, based on which the school will support the company in launching a service direction for building energy use simulations in Võru. In March, EWERS will open adult training to help Zeroedition find and prepare employees with the necessary competence.
The IDA ICE (Indoor Climate and Energy) basic training conducted in cooperation focuses on teaching the skills necessary to create simulations of the indoor climate and energy use of buildings. The training offers a unique opportunity to get acquainted with the IDA ICE software, which enables building-based research of indoor climate phenomena and energy use.
The training will take place from March 4 to 25, on Tuesdays and Thursdays from 4:00 PM to 6:30 PM in the computer classroom of the EWERS Tehnomaja.

The Minister of Infrastructure and the Mayor of Võru got acquainted with the activities of Zero Edition OÜ
On February 3, the Minister of Infrastructure Vladimir Svet, together with the Mayor of Võru Kalvi Kõva and Member of Parliament Anti Allas, visited the Jaama 32 companies. First, they went to the Werroform production workshop to be introduced to the renewed product range and the newly manufactured and unique energy cube, which is planned to be brought to the market more widely through SCT to spread energy saving. The visit ended at the ZeroEdition office, where the management described our main goals and at the same time used the opportunity to explain to the minister the limitations of solving the Estonian energy topics and the closed system of issuing energy certificates. The symbiotic ideology of all our companies impressed all members of the delegation.
Same day ZeroEdition Estonian office started work with two new employees. The future goal is to have around 25 persons working with building simulations by 2026.

Knowledge and practice hand in hand: TalTech visit
Taltech bachelor's and master's students, together with their professors, visited ZeroEdition and Werroform on their own initiative on 21.01.25. To start off, Jon Ritter from Swiss Ritter&Schumacher architect bureau introduced the human-oriented approach to environmentally and material-conscious residential construction, so that the guests could understand our new and transparent energy-efficient planning and the resulting choice of materials for the most cost-effective construction. The presentation was followed by the tour of the factory, where the CEO of Werroform, Bernhard Wallner, introduced the 25 guests to Smart products and the principles of their manufacturing, as well as continuous development activities for the best use of those elements and materials. The students were excited to see that at the same time, 10 elements were being manufactured in the factory, to be taken for testing to TalTech construction laboratory by end of January. The cooperation with TalTech is highly visible and two-sided in every sense. This is how we can put knowledge into practice and develop as a society.

Cantonal Office for Energy, Graubünden (Switzerland) confirms funding for heating replacement with air absorber
On 20 January 2025, a meeting took place between Jon Ritter, representative of Zero Edition, and Mr. Casutt from the Office for Energy of the Canton of Graubünden. The topic was the heating replacement carried out in November 2024 in the Calunastrasse project in Chur.
The property owners wanted to switch from fossil gas to a heating system using renewable energies. A solution with geothermal probes was out of the question for reasons of space, and an air source heat pump was not possible due to noise pollution. The heating planner Claudio Secomandi suggested as an alternative the replacement of the heating system using air absorbers and a brine heat pump.
Zero Edition used a building simulation (Curia dossier) to calculate and design the air absorber and heat pump. The system went into operation on 20 November 2024. Using a monitoring dossier, Zero Edition presented the current operating figures for the heating system and was able to prove that the simulated values are very close to the actual measured values. Mr Casutt from the Office for Energy was pleased with the high efficiency of the energy generation and the above-average COP value of the heat pump in the winter months of December and January.
As a result, the Office for Energy of the Canton of Graubünden confirmed the payment of the promised subsidies for the air absorber heating replacement.

Logic: DESIGN - CONSTRUCTION - ENERGY
is replaced by new logic
ENERGY - CONSTRUCTION - DESIGN
Jon Ritter, the shareholder of ZeroEdition is implementing this necessary paradigm shift in the architecture industry.
Once the questions regarding energy and structural requirements have been clarified at the outset, the construction for the project can be determined precisely and it forms the basis for design. All this gives architects a range of options at an early stage, with what they can freely operate, making the planning process more efficient and thus avoiding unnecessary construction costs.
Zero Edition uses dynamic building simulations to make precise statements about component dimensions and building services requirements prior to planning.
