An essay on technology, energy, and societal transformation in TEK26’s horizon
A building seems to be standing still.
It rests against the ground with walls, windows and ceilings, measured in millimeters and attached to the map with coordinates. Yet it is never motionless. It draws heat from the ground, receives rain, breaks the wind, filters daylight, and lets people in and out. Through cables, pipes and digital signals, it is connected to power plants, data centers, water reservoirs, roads, forests and factories. A modern building is therefore not just a construction. It is a hub in society’s metabolism.
It is in this realization that the building regulations of the future must begin.
When we talk about TEK26, we are not yet talking about a final regulation with a closed set of paragraphs. Rather, we are talking about a horizon: a modernisation of building regulations, a movement towards simpler rules, clearer documentation and greater opportunities to substantiate that new solutions actually meet society’s requirements. In 2026, the Norwegian Building Authority has specified that analysis can be used to develop its own solutions, and that pre-accepted services should not necessarily function as an invisible roof over innovation.
This may sound like a technical adjustment in the guidance of a set of regulations. In reality, it touches on a larger question: How should a society regulate a future it does not yet know?
From minimum requirements to social mission
Building regulations have traditionally been society’s protection against the indefensible. They are intended to prevent roofs from falling down, from fire from spreading uncontrollably, from moisture from breaking down structures, and people from being excluded from rooms they should be able to use. The regulations draw a legal line between what is acceptable and what is unacceptable.
But the climate crisis, the loss of nature and the pressure on the energy system have given this limit a new meaning. It is no longer sufficient for a building to be safe. It must also be asked what the building requires of the world while it is erected, used, modified and finally dismantled.
Where did the materials come from? How much emissions occurred in production? How much power does the building draw on the coldest morning of the year? Can the components be repaired? Can the rooms get new functions? Can the concrete, steel, wood and glass be used again?
Here, Norwegian and European standards become a form of collective memory. NS-EN 15978 provides a method for assessing the environmental performance of buildings through life cycle analysis and quantified environmental data. NS 3720 provides a Norwegian framework for calculating greenhouse gas emissions from all or part of a building’s life cycle, from material production and construction to operation, conversion and disposal.
These standards do something crucial: They shift attention from the moment the building is completed, to the entire time the building exists.
A building can be energy-efficient in operation and at the same time be burdened with large emissions from the materials. Another can have a modest technical expression, but be built for a long life, reuse and changing needs. The life cycle perspective teaches us that sustainability cannot be photographed by handover. It must be considered as a story with a beginning, middle section and end – and preferably with the possibility of a new beginning.
Built as a participant in the power system
In the old energy system, the building was the end point. The electricity was produced far away, transported through the grid and used when the resident turned on the stove or light.
In the new energy system, the building will be a participant.
Solar cells can turn the roof into a power surface. Batteries can shift energy use in time. Heat pumps can obtain energy from air, sea or ground. Thermal bearings can preserve heat from low-load hours to high-demand hours. Digital control systems can reduce ventilation, charging or heating for short periods of time without losing comfort. Thus, thousands of buildings can collectively act as a distributed energy reserve.
The NVE points out that energy-flexible buildings can contribute to better utilisation of the electricity grid. The flexibility can lie in heating, cooling, waterborne systems, local energy production and geothermal heating, among other things.
This changes the architecture in a way that is not always visible. The most important new feature of a building may be the ability to wait.
It can wait to charge the car. Wait to heat the tap water. Lower the power output during the hour when the power grid is most loaded. Use self-generated energy when the sun is shining, and stored heat when the cold puts pressure on the system.
This ability to shift consumption is not just a matter of technology. It is a new form of solidarity. The building does not necessarily dramatically reduce its overall energy demand at any given moment, but it adapts to the whole. It behaves like a responsible citizen in the energy system.
The Digital Twin’s Promise
As buildings are filled with sensors, they also become more readable. Temperature, air quality, energy consumption, solar radiation, occupancy and technical condition can be recorded in real time. When this data is connected to a digital model of the building, what is often referred to as a digital twin occurs.
The name may seem futuristic, but the principle is simple: The physical building gets a digital counterpart that can be used to understand what is happening, predict what will happen, and try out measures before they are implemented.
A digital twin can warn that a pump is using more energy than normal. It can simulate how the indoor climate is affected if ventilation is reduced for a quarter of an hour. It can show which building parts are nearing the end of their technical life, and which materials can one day be dismantled and reused.
In this way, documentation can go from being a pile of static files to becoming a living knowledge structure.
But the digital build also introduces new vulnerabilities. Who owns our home, workplace, and movement data? Who can change the algorithms that control heating and ventilation? What happens when a system is no longer supported by the vendor? And how do we ensure that an intelligent building does not become a building that only experts and technology companies understand?
Technology can make buildings more efficient, but not automatically more democratic.
Therefore, the standards of the future must be about more than energy performance and data quality. They must also ensure transparency, cybersecurity, interoperability and human control. A building that teaches must still be explainable. A building that optimizes must still be able to be overridden. A building that collects data must be subject to clear boundaries.
Analysis as the responsibility of innovation
A more function-based and analysis-oriented building technology regulation can open the door to solutions that today’s checklists have not foreseen. It is necessary. No regulation can describe in advance all future materials, energy systems, facades, forms of storage or digital control methods.
But freedom from detailed requirements is not freedom from responsibility.
When a project chooses a non-traditional solution, it must be able to document why the solution is secure, robust and suitable. Innovation cannot be built on enthusiasm alone. It must withstand calculation, control, criticism and verification.
Here, the standards have a dual role. They are both bridges and railings. They make it possible to compare options, document performance, and establish a common language between developers, architects, engineers, governments, contractors, and users. At the same time, they prevent words such as “smart”, “circular”, “emission-free” and “sustainable” from being reduced to decorative labels.
In an analysis-based building culture, the question is not just whether a solution is new, but whether it is demonstrably better.
It requires expertise. Small municipalities and smaller enterprises must have a real opportunity to understand and assess advanced analyses. Otherwise, function-based rules can create a society where the largest players are given freedom of innovation, while the smaller ones are left with uncertainty and costs.
Technological progress must therefore be accompanied by institutional capacity. Education, standardisation, supervision, open calculation methods and sharing of experiences are not administrative background work. They are the very infrastructure for responsible innovation.
The most sustainable building may already exist
The narrative about technology often points forward to what has not yet been built. But the Norwegian social transformation will largely take place within walls that already stand.
Office buildings will become housing. Shopping centres will house health services, workshops and culture. Detached houses must be adapted to several generations. Materials from demolition projects will become raw materials for new constructions. Energy systems will be upgraded without replacing the entire building.
This requires a different conception of architecture. The building must not be understood as a finished product, but as a structure in constant negotiation with the times.
What is optimal when opening may be unsuitable twenty years later. Floor plans, technical guidelines and load-bearing systems should therefore allow for change. Flexibility becomes an environmental property because it extends its service life. Repair becomes an energy strategy because it reduces the need for new production. Reuse becomes a design premise because the materials are no longer considered waste, but as temporarily placed resources.
The circular economy begins when we stop designing buildings as if they should never be changed.
The paradox of efficiency
It is tempting to believe that more efficient technology automatically results in a lower overall load. History shows that the connection is not so simple. When something becomes cheaper or more efficient, we may end up using more of it.
A better insulated house can be built larger. Efficient lighting can stay on for longer. Digital services can reduce transport but increase the need for data centres and electronics. Solar cells can provide cleaner energy, but also strengthen the notion that energy consumption no longer needs limits.
Therefore, societal transformation cannot be reduced to technical optimization. We also need to discuss adequacy.
How much space does a good life need? How many technical systems must a building contain? When is rehabilitation better than demolition? When should energy be used for comfort, and when should it be released for industry, transport or other societal needs?
The NVE has previously assessed that it is technically possible to reduce electricity consumption in buildings significantly up to 2030, but that this requires extensive efficiency measures. It suggests that the building sector is not just a consumer that needs to be supplied. It is also an energy reserve that can be released.
The cleanest kilowatt hour is still the one that does not need to be produced, transported or stored.
A new relationship between home and infrastructure
In the industrial society, the infrastructure was often invisible. The water came from the tap, the power from the socket and the heat from the radiator. The large systems lay outside the everyday consciousness.
The energy transition makes them visible again.
Electricity prices vary. Solar production follows the weather. The electric car competes with the heating for the capacity of the house. Local energy communities can share production and storage. Neighborhoods can balance needs across buildings.
This can give people greater influence, but also greater responsibility. The individual citizen risks being turned into an energy manager, data administrator and technical operations manager in their own home. If the transition is to be socially sustainable, the systems must be understandable and inclusive. They must also work for those who do not have the time, finances or interest to monitor a digital energy panel.
The smart society cannot demand that all citizens become engineers.
Automation must therefore be designed as care, not as burden. Technology should protect people from complexity without depriving them of control. The benefits from flexibility and energy efficiency must be distributed fairly. Otherwise, the energy transition may reinforce the divide between those who can afford solar cells, batteries and rehabilitation, and those who are left in draughty homes with high costs.
A regulation can set requirements for the building. A social transformation must also make demands on justice.
When the rules become culture
The most important effects of TEK26’s world of ideas may not be directly visible in the text of the regulations. They will show up in what the construction industry perceives as normal.
That greenhouse gas calculations are carried out early, not after the crucial choices have been made.
That energy flexibility is treated as part of the building’s social value, not as a technical extra.
That demountability is considered quality.
That data from operations is used for learning.
That architects ask how little needs to be built.
That engineers design for both safety and change.
That developers measure value over several decades, not just up to sale.
That the users’ experiences are included in the assessment of whether the building actually works.
Then regulation has gone from being an external duty to becoming an internal culture.
The building of the future is a relationship
We have long considered buildings as objects: How tall are they? How much do they cost? How many square meters do they hold? How much energy do they use per year?
In the future, we must consider them to a greater extent as relationships.
The relationship between the material and the landscape from which it was taken. Between energy use and the power grid. Between the indoor climate and the body. Between the data and privacy. Between the investment today and the room for manoeuvre of the generations that come after us.
TEK26’s deepest potential therefore does not lie in a specific insulation thickness, energy framework or calculation method. It lies in the transition from buildings as isolated products to buildings as responsible parts of larger systems.
A truly intelligent building is not necessarily the one that has the most sensors. That is what understands its place.
It consumes energy when the system can handle it. It takes care of the materials that have already been extracted from nature. It protects the people who stay there. It can be changed without being destroyed. It can document its qualities without hiding its weaknesses. And when one day it is no longer needed, it leaves behind not only waste, but opportunities.
In this way, the construction technique becomes political, even when it is expressed in tables and calculation models. It determines what resources we bind, what risks we accept, who gets access to good spaces, and how much freedom we leave to the future.
A building never stands still.
It moves energy through society. It shapes habits, costs, and lives. It carries the materials of the past and the consequences of the future in the same constructions.
The question is therefore not only how we should build houses that satisfy the next regulation.
The question is how to build a society worthy of the houses we have not yet erected.
