Paris Room with a view

The home of Victor Hugo in Paris offers a splendid view of the Place des Vosges. The image taken from the 1st floor of the building and his living room allows to see a bit like what Hugo saw every day for some time. A small park, probably a lively street with arcades full of shops and people. Lots of inspiration and observation which may come from actual life. The actual time of writing, however, needs also retreat from the busy daily surroundings to focus one’s mind. All this hasn’t changed since Hugo lived in Paris at this address. Writer in residence programs of today allow authors to focus on their work beyond daily tasks. Cultural advances heavily rely on such programs nowadays to be able to have at least temporarily “A room with a view”.

Social learning

The process and mechanisms that drive social learning are still not well understood. Beyond social psychology and sociological theory and evidence, neuroscience has made progress worth taking note of. The paper by Maciej Winiarski et al. (2025) offers a key insight into the neuro-biology of learning about social structures and the behavioral consequences. In their study of mice in the EcoHAB supervised group housing, information sharing through scent was the driver of learning about the social structure and the ensuing social behavior. The various experimental settings show that 1-2 mice became the most relevant informants about social structure and rewards. The “exploratory activities” are an interesting underlying parameter as well. The mus musculus model does not tell us much about humans yet, but we get a gist of important factors to consider for social learning in groups or organizations. Information seeking, informants, reward structures and “housing” have to be considered based on such research from neuroscience.

Inclusive design

In aging societies inclusive design is not an option but a must have. This is neither a short term fix nor a renovation without costs. Adapting a home to a wheelchair use is an expert job as you have to think about issues you have not experienced yourself before in most cases. Door thresholds and openings, better have sliding doors as much as possible, have to be considered early. Bathroom adaptation in size and height, toilet space and lighting switches all should be planned ahead. There exists a DIN Norm 18040 which specifies measures precisely. In the age of AI-vibe coding some home appliances could be programmed to follow a person’s voice commands as well. For the time being in 2026-7 this is a nice to have option. but early installations of “intelligent digital devices” beyond a washing machine or microwave can get you quite far in the near future. Inclusive design could open doors and switch on lights simply by talking to your smartphone.

In Through Out

The easy logic “In Through Out” has multiple applications from nutrition, data processes and process engineering. An obvious experience for everyone is the cooling of an apartment during a meteorological heatwave. The energy loss known during winter times from a blow out of warm air through gaps in windows or doors reverses during summer to become a “blow in” of hot air from the surroundings of an apartment. The throughput, is the relevant measure to watch out for. This means the amount of air exchange during a minute of maximum or minimum airflow. It has a direct effect on temperatures and humidity levels. For cooling purposes, try to maximize the throughput at times when the temperature difference is the largest. Easy exercise, just a bit early in the morning. Mechanical, chemical or electrical devices may assist the amounts of throughput as well. Process engineering is for all of us and at all seasons.

Cooling-Heating Renovation

The public and scientific debate about the added value of investments in renovation of buildings has been ignited by the recent heat wave in Europe. Some renovations that were primarily concerned to safe energy in winter through better isolation of walls, doors and windows found themselves less well prepared with isolation against heat and sunlight. Hence, it makes sense to consider both topics, cooling and heating of buildings, jointly.
Reversible heat pumps can do this trick, if isolation has been installed or applied during renovation already. Additionally, materials used for isolation of buildings should show 2 measures for isolation: thermal conductivity and thermal resistance (R-value). Comparing both gives a fair idea about isolation quality in periods of heating and cooling needs. Albedo values are interesting as well as heat input during a sunny day is welcome in winter, but not during summer heat waves. The commonly used Energy Performance Certificate (EPC) for a building needs to be checked whether it is sensitive to excessive heat as well. (Image: BNF in Paris 2026)

Ensor Home

There are few artists who stayed in their home for almost all their life. James Ensor was a personality who was profoundly attached and continually attracted to his native city of Ostend. After a short and unsuccessful spell at the Brussels art academy, he returned to his parents’ home and due to a heritage from an uncle, he could live in a nearby house, which also served him as his atelier. Although I did not come across documents that showed he had traveled a lot, nowadays his art work is spread across the globe. The seaside resort of Ostend was a real tourist destination and, therefore, many famous people of the 1st half of the century passed by and met with Ensor there. Not only fellow artists, but also scientists like Albert Einstein. Critical minds and people searching beyond the trodden paths must have been attracted to him, a personality who dared to challenge conventional painting and techniques of his time. A reconstruction of his atelier and several animations give a lively modern touch to his work and living style. My take home message from the Ensor Home: The search for inspiration might be just around the corner. 

Premium for silence

People are willing to pay a premium on housing prices for a more silent environment. In the study Enrico Moretti & Harrison Wheeler (2025) estimate that the construction of a silencing wall near a noisy traffic junction or road will increase prices for every decibel of noise reduction by about 3%. Distances closer to the noise shields get higher increases and this mechanism works even up to 400 meters away from the isolation. The investment in decibel noise reductions (not statistical noise) meets a willingness to pay a premium on housing prices. Investment in positive environmental effects (silence) have an obvious marketable premium value. This is most likely just the obverse effect that noise nearby housing is penalized and part of the social mechanism of gentrification. Housing prices and rental costs are known to be powerful drivers of gentrification as well.

Home Wind energy noninvasive

The abundance of wind energy in some regions has made the use of this source of energy more popular. During long winter nights the harvest of wind energy is a wonderful source of free energy. Regulations and oversize wind turbines have tarnished the image of wind energy in some regions. However, even in France and not only in this small village of Asterix and Obelix who resist the Roman empire, that we can find tiny wind turbines providing small amounts of energy. For all those households that have a battery they can use this power whenever they may need it. Suddenly, we are looking forward to the stormy autumn season.  

Popular Sociology

Sociology, like other social science disciplines, has often difficulties in reaching bigger audiences. However, in combination with a museum which specializes in the history of a big city like Paris, the insights can suddenly become very popular. The “Musée Carnavalet of the history of Paris” has mounted an exhibition, which builds on the population censuses of 1926,1931 and 1936. The access to the complete original records of 3x about 2 millions of people has become a national treasure for social scientists and the public at large.
People flock to the exhibition. Some do it to learn about the past of their districts or streets. Others to learn about historical facts, which are sometimes linked to the family anecdotes and broader historical narratives. Out of this interest grows an understanding of macro- and micro-level social processes, which makes use of basic statistics.
People ask themselves: Is your (family) story unique or is it part of a more general pattern or social process like urbanization or social mobility.

All electric now

The shift over to the “All electric society” is easiest in sunny states like California in the USA, Africa or Southern Europe. For other regions of the globe not only the production of energy through the sun is a bit less abundant, but the storage of the sun’s energy production for deferred use is the next challenge. Countries of the globe near the equator have to balance 12 hours daylight with 12 hours night, countries far from the equator have to balance additionally more long-term between short winter days and long summer light.
Different energy storage solutions have to be envisaged.
On a daily basis or even weekly basis, battery energy storage systems (BESS) can do the trick. These systems become more costly for high capacity, longer duration storage. Battery size and price quickly become an issue. The number of electric vehicles (EVs) that have this more intelligent BESS is rising. This makes it possible to eventually use this storage capacity, if your car is sitting around your home or office for most of the time anyway. To make the “all electric society” function 24 hours, energy storage has to be planned at the same time as production and consumption patterns. The all electric prosumer will be the de-central “pro-store-sumer” in the 21st century.
