How night setback actually impacts the indoor temperature of a building with communal heating

Laura Verdier — Tue, 19 May 2026 13:23:11 +0000

Night setback is one of the simplest parameters to adjust in the control system of a communal boiler plant. Yet in many buildings it is either absent or ineffective: nighttime indoor temperatures remain almost identical to daytime temperatures, resulting in unnecessary gas consumption.

This article presents an analysis of data collected from two residential buildings between March 15 and April 3, 2026, before and after a change to the control settings. The aim is to observe how this change translated into the indoor temperature curves, and to draw lessons from it about the thermal dynamics of these buildings.

Observation protocol

Buildings

The two buildings, referred to here as André Bollier and Yves Farge, are residential buildings with communal heating, controlled by the same heating loop. The dwellings are fitted with indoor temperature sensors that allow continuous monitoring of the average temperature per building.

The period

The observation period spans 19 days, from March 15 to April 3, 2026. It is divided into two distinct phases:

Phase 1 (March 15–27): observation with no change to the setpoint, baseline state
Phase 2 (March 28–April 3): observation after the night setback was changed

Phase 1: thermal state before the change (March 15–27)

Indoor temperatures observed

In this first phase, both buildings show high and stable average indoor temperatures:

Night/day variation

	Building	Average indoor temperature
Bollier	~22–23 °C	< 0,5 °C
Farge	~22,5–23,5 °C	< 0,5 °C

A night/day variation below 0.5°C indicates that the night setback, if it was set at all, had no measurable effect on the indoor temperature. The buildings maintained a near-constant temperature over 24 hours.

Interpretation

Several factors can explain this lack of an effective setback:

High thermal inertia: concrete or stone buildings store heat and release it slowly. If the supply setpoint is not lowered early enough or sharply enough, the inertia offsets the setback before it can translate into indoor temperature.”
Insufficient setback value: lowering the supply temperature by 2 to 3°C may not be enough to produce a visible effect indoors if the building is well insulated or if internal gains (occupants, electrical appliances, sunlight) are significant.
Poorly timed schedule: if the setback starts too late or ends too early, the window of reduction is too short to show up in the hourly averages.

In this specific case, the high temperatures (~23°C) also point to structural overheating: the building heats more than necessary to reach the regulatory comfort level (19°C when occupied, under Article R.131-20 of the French Construction Code).

The parameter that was changed

On March 28, two adjustments are made to the heating loop’s control settings: a reduction of the daytime supply setpoint, since the building was structurally overheated (~23°C for a regulatory comfort level of 19°C), and a further reduction over the nighttime period, in order to activate an effective night setback. No physical changes are made to the system.

Phase 2: behavior after the change (March 28–April 3)

Évolution des températures intérieures

As early as March 29 (D+1), the temperature curves of both buildings change markedly:

Building	T° before change	T° after change	Average difference
Bollier	~23 °C	~21,5 °C	−1,5 °C
Farge	~23,5 °C	~22 °C	−1,5 °C

The night/day variation goes from less than 0.5°C to about 2°C, which confirms that the night setback is now effective and visible in the indoor data.

What the curves show

Three phenomena are visible in the post-change data:

1. The nighttime descent
The indoor temperature starts to drop in the evening, follows a steady slope through the night, and reaches its minimum in the late night / early morning. This profile is characteristic of a building whose heat input is reduced during the nighttime period and whose thermal inertia gradually accompanies the descent.

2. The morning recovery
The temperature rise in the morning is fast and consistent with a return to the normal setpoint. The building’s thermal inertia plays a positive role here: the mass of the structure quickly absorbs heat from the heat-transfer fluid during the restart, which limits the time needed to climb back up.

3. The consistency between the two buildings
The two buildings, though distinct, respond very similarly to the same setpoint change. This indicates that their thermal characteristics (inertia, heat loss, occupancy) are close, and that the control system is well sized for both.

Analysis: why is the drop 1.5°C and not more?

The 1.5°C drop in the 24-hour average results from the combination of the two adjustments, not from the night setback alone:

Lowering the daytime setpoint brings down the building’s daytime baseline (the daytime peak goes from around 23°C to ~22.5°C), directly correcting the overheating.

Methodological takeaways

Limiting confounding variables

Over this period, the outdoor temperature continued to fluctuate normally across the two phases. For a rigorous analysis, it would ideally be necessary to:

Compare against a control building left unchanged over the same period
Normalize the data against the outdoor temperature (heating degree days)
Extend the post-change observation period to smooth out transient effects

The data presented here gives a robust indication, but a degree-day analysis would make it possible to quantify the associated energy savings more precisely.

The thermal time constant as a key indicator

The speed at which a building responds to a setpoint change depends on its thermal time constant τ, which reflects the ratio between its thermal capacity (inertia) and its heat loss. A building with a time constant of 20h will respond much more slowly to a setback than a building with τ = 8h.

At André Bollier and Yves Farge, the response visible as early as D+1 suggests relatively short time constants, which makes these buildings particularly responsive to setpoint control.

Comfort threshold and room for maneuver

The post-change temperatures (21.5°C and 22°C) remain above the regulatory threshold of 19°C during occupancy. The initial margin was therefore large (~4°C of overheating), which explains why a 1.5°C drop did not cause any discomfort. In buildings already close to the threshold, the same adjustment would produce a different effect.

Conclusion

This analysis illustrates how a simple parameter change — adjusting the night setback — can produce a measurable effect on the indoor temperature of a building with communal heating, visible the day after activation.

Key takeaways:

An ineffective night setback is common in buildings with communal heating, even when it is formally configured
A building’s response depends on its thermal inertia: the lower it is, the more effective and faster the setback
A significant initial overheating (>> 2°C above comfort level) is the favorable condition for effective control without risk of complaints
The consistency of the response across two distinct buildings on the same heating loop validates the relevance of centralized control

The natural next step would be to cross-reference this temperature data with gas consumption data, in order to precisely quantify the energy savings in kWh and as a percentage of seasonal consumption.

Data collected via the continuous monitoring system of the Kocliko platform, period from March 15 to April 3, 2026.

Improving your condominium’s EPC rating: the method (without major works from the start)

Laura Verdier — Tue, 28 Apr 2026 14:24:40 +0000

For many condominiums, the collective EPC is still seen as just another obligation: a document to be produced, filed, and presented at the general meeting. However, when properly utilized, it is one of the most powerful levers for managing a building’s value, occupant comfort, and service charges, without necessarily committing to heavy works in the first year. Here is the method to improve your condominium’s EPC rating step by step, starting with high-impact actions and a controlled budget.

The collective EPC, much more than a regulatory obligation

With the gradual rollout of the Climate and Resilience Law, the timeline is tightening for condominiums. Properties rated G are already banned from the rental market, F-rated ones will be in 2028, and E-rated ones in 2034. For buildings with an F or G rating—the “energy-inefficient properties”—the pressure is twofold: the risk of lost rental income for landlords and spiraling heating costs for owner-occupiers.

But the collective condominium EPC is not just a compliance document. It is also:

a quantified snapshot of the building’s consumption and emissions,
the baseline for measuring the impact of every action taken,
the foundation that feeds the Multi-Year Works Plan (PPT).

Provided it is used actively, rather than just being endured.

Improving the EPC rating: starting with “low budget, high impact” actions

What surprises most supervisory boards is that it is often possible to save several percentage points in heating consumption, and sometimes gain an entire rating, without breaking a single wall. Before external wall insulation or replacing the collective boiler, several targeted interventions deserve consideration.

A More Intuitive Reading of Energy Data

To facilitate interpretation, dwellings are colored according to their temperature. A color code ranging from blue to red allows for immediate identification of colder or warmer areas within the building.

This spatial representation transforms the way energy data is observed. Where analysis traditionally relied on tables or graphs, KOCLIKO 3D now allows for the direct visualization of information within the building’s structure. Data thus becomes much simpler to understand and analyze.

Sludge removal from the heating network

Over the years, sludge (corrosion residues, mineral deposits) accumulates in pipes and radiators. As a result, heat transfer is poor, some radiators remain lukewarm, and the boiler works unnecessarily hard. Collective heating sludge removal, supplemented by a corrosion inhibitor, can generate 5% to 15% in heating savings, without any intervention inside the apartments.

Hydraulic balancing of networks

When some apartments overheat while others stay cold, it is often a balancing issue. Adjusting the flow rates of each column or outlet improves comfort and reduces consumption, generally by 10% to 15%.

Management and regulation of collective heating

Outdoor sensors, programmers, adapted heating curves, and thermostatic valves in apartments: these are all levers that can save 5% to 20% depending on the initial situation. Often, the return on investment is less than three years.

Lagging of pipes in common areas

Heating and domestic hot water pipes passing through cellars and technical rooms often radiate heat into empty space. Lagging them (insulating them with shells or sleeves) limits these losses—a modest investment that pays for itself in less than two years in most cases.

Combined, these actions allow many condominiums to gain an EPC rating or prepare the ground before more structural insulation or system change projects.

The real challenge: prioritizing the right works

The classic trap in condominiums is the opposite of inaction: committing significant expenditure to areas that do not account for the most consumption, or without having measured the real potential for gain.

Three questions should guide every decision:

Which area consumes the most in the building (heating, DHW, ventilation, building envelope)?
Which works scenario provides the best cost / energy gain / rating jump ratio?
How to measure the real impact once the works are completed, to validate the trajectory and adjust?

This is precisely where a decision-support tool changes the game.

Kocliko: generating the collective EPC and managing its improvement roadmap

Kocliko is not limited to the regulatory generation of the collective EPC. The solution supports condominiums throughout their energy roadmap with four complementary modules.

3D Building Modeling

Each building is rendered as a detailed 3D model that allows for the concrete visualization of the envelope, heat loss, and critical zones. Much more meaningful than an Excel spreadsheet for a supervisory board or a general meeting.

Based on the model, Kocliko generates several quantified scenarios: attic insulation, EWI, window replacement, system replacement, or combinations. For each scenario, you can view the projected EPC rating, the estimated energy savings, the budget, and the carbon trajectory.

Based on the model, Kocliko generates several costed scenarios: attic insulation, external wall insulation (EWI), window and door replacement, system replacement, or combinations. For each scenario, you can view the projected EPC rating, the estimated energy savings, the budget and the carbon trajectory.

Digital twin updated retrospectively

Once the works are completed, the building’s digital twin is updated: it reflects the reality of the property, not the original theoretical version. A key point for condominiums that carry out their operations in phases over several years.

Real-time and continuous impact measurement

Real energy data (consumption, temperatures, equipment operation) is integrated to measure the effect of actions as they happen. No more waiting for the annual bill to know if an intervention has paid off.

Building your condominium’s EPC roadmap

Moving from F to D, or even F to C, is not a dream. It is a roadmap that is built by intelligently layering:

simple and quick actions (sludge removal, balancing, management),
targeted projects on the areas that truly matter,
continuous measurement to adjust along the way.

All while keeping two often-perceived contradictory objectives in sight: budget control for the condominium and sustainable energy performance for the building. With the right tools, this equation has a solution.

3D KOCLIKO: A New Building Visualization to Understand the Temperature of Each Dwelling

Laura Verdier — Mon, 09 Mar 2026 13:59:35 +0000

The KOCLIKO platform is enhanced with a new feature: 3D building visualization directly within the manager’s interface. This 3D KOCLIKO allows for a more intuitive representation of a residence and enables observation of the thermal situation dwelling by dwelling.

Thanks to this new interface, managers and operators can visualize the temperature of dwellings directly at the building scale. A simple color code makes it possible to immediately identify colder dwellings, those overheating, and those within the thermal comfort zone. This approach offers a new way to interpret energy data and better understand a residence’s thermal behavior.

A 3D Model Based on the Building’s Digital Model

The 3D KOCLIKO relies on the building’s digital model, which describes its structure and internal organization. This model contains detailed information on the various elements that make up the residence, such as floors, dwellings, rooms, and architectural volumes.

From this data, the platform generates an interactive 3D model of the building directly within the Kocliko interface, allowing for intuitive navigation within the residence and visualization of dwelling positions.

Visualize the Temperature of Each Dwelling

The 3D KOCLIKO is not limited to building representation. It also integrates data from sensors installed in dwellings, particularly ambient temperature measurements.

Each dwelling represented in the model is associated with the corresponding sensors in the KOCLIKO platform. The collected data is then displayed directly in the 3D visualization. This makes it possible to observe the temperature of each dwelling at the building scale and quickly compare thermal situations between apartments.

This representation also facilitates the identification of atypical situations, such as an overheating dwelling or an insufficiently heated apartment.

A More Intuitive Reading of Energy Data

This spatial representation transforms the way energy data is observed. Where analysis traditionally relied on tables or graphs, 3D KOCLIKO now allows for direct visualization of information within the building’s structure. Data thus becomes much simpler to understand and analyze.

A New Analysis Tool for Technical Teams

By combining the building’s digital structure with data reported by sensors, 3D KOCLIKO offers a new way to explore the thermal performance of residences.

Technical teams can thus quickly visualize the thermal situation of a building, understand any discrepancies between dwellings, and more easily analyze the overall behavior of the building. This interpretation facilitates the identification of abnormal situations and allows for more effective intervention when necessary.

With this feature, KOCLIKO continues its objective: to make energy data more readable and operational to better understand buildings and improve their management.

Procivis network New Year greetings: a key moment to take stock, share challenges, and look collectively toward 2026

Laura Verdier — Tue, 27 Jan 2026 13:48:40 +0000

At the beginning of this year, Procivis gathered its entire ecosystem for its New Year greetings ceremony.

An important event for the housing sector, serving as both a review of the past year and a time to project toward future challenges.

Present on this occasion, we had the pleasure of participating in these exchanges, which allowed us to look back at the progress made, identify the structural challenges that remain, and reiterate the importance of collective mobilization to sustainably meet housing needs.

A speech resolutely focused on action and optimism

On the occasion of his greetings, Yannick Borde delivered a speech resolutely focused on optimism, highlighting Procivis’s desire to continue its role as a committed housing player, support the sector’s transformations, and strengthen its social utility.

In a context of lasting tension in the housing market, he recalled an essential point:

the recognition, at the highest level of the State, of the scale of housing needs is now established. But beyond observations and announcements, the challenge is clear: act collectively, accelerate, produce, and succeed together.

His intervention also highlighted a strong signal for the future of the sector:

for the first time, the entire housing industry has mobilized in a united manner. Overcoming traditional oppositions—between social and private, old and new, owners and tenants—now appears to be an indispensable condition for the sector’s resilience.

Because if one branch weakens, the entire housing chain suffers the consequences.

The message is clear: housing is a collective issue that calls for collective responses.

French innovation at the heart of the exchanges

This ceremony was also an opportunity to recall the key role of innovation in the transformation of the real estate sector.

In this regard, Éric Vorger, CEO of Kocliko, spoke to thank the Procivis network for allowing French technology companies to actively contribute to the evolution of collective housing.

He stressed the importance of bringing forth, supporting, and deploying innovation, particularly when it addresses concrete issues of energy performance, comfort, and sustainable building management.

During his intervention, Éric Vorger revisited the fundamentals of the Kocliko approach:

a commitment to results undertaken,
the deployment of solutions in more than 31,000 homes,
and a strong conviction: energy performance can only be sustainable if it is equitable.

Performance that aims to guarantee consistent comfort, limit situations of overheating or discomfort, and ensure better control of service charges for all occupants.

Making the collective a lever for sustainable transformation

Throughout the speeches, a common thread emerged:

in a sector facing major social, environmental, and economic challenges, no response can be isolated.

The Procivis greetings ceremony served as a reminder of how much cooperation between stakeholders—cooperatives, landlords, companies, startups, local authorities, and institutions—is now essential to build sustainable and operational solutions.

In conclusion

The Procivis network greetings ceremony was much more than a formal institutional event at the start of the year.

It constituted:

a time to reflect on the past year,
a moment of clarity regarding the challenges that remain,
and above all an invitation to continue collective action.

At Kocliko, we are proud to have participated in these exchanges and to contribute, alongside Procivis and the entire ecosystem, to sustainably evolving the performance and equity of collective housing.

Heating Season Kicks Off: Our Energy Managers’ Tips for a Budget-Friendly Winter

Laura Verdier — Wed, 15 Oct 2025 14:11:01 +0000

Every year, around October 15th, most landlords kick off the heating season.

This symbolic date marks the start of a collective challenge: providing enough heat to ensure tenants’ comfort, while avoiding energy waste and overconsumption.

Between rising energy prices, regulatory requirements, and thermal comfort concerns, the winter period confronts managers with a delicate balance: keeping heating under control without compromising occupant satisfaction.

And even before we get into technology, there are simple, effective measures to start the season off right.

Here, our Kocliko Energy Managers share 5 practical tips to support the start of the heating season, then explain how Kocliko technology makes it possible to go further in energy efficiency and performance.

1️⃣ Putting off the heating a bit… naturally

Holding off on turning the radiators back on often helps extend the savings built up over the summer.

The body adapts quickly: a sweater, a blanket, or a throw are sometimes worth a few degrees of heating!

💡 Every day gained before turning the heating back on means energy saved, with no loss of comfort.

2️⃣ Optimizing control on the manager’s side

Before the season kicks off, managers play a key role:

Checking the boiler room control settings,
Insulating the pipes in unheated areas,
And scheduling a power flush if necessary.

After an energy retrofit (for example, external wall insulation done over the summer), remember to reconfigure the control settings: the building’s needs have changed!

3️⃣ A few alternatives depending on nuance:

Occupants can play their part in energy moderation too:

Keep windows and doors closed during the heating season,
Open the shutters during the day to capture solar heat 🌞,
Close them at night to keep the heat in,
Set the thermostats to 19°C in living areas and 17°C in bedrooms.

Simple steps, but decisive ones for limiting heat loss and stabilizing indoor temperature.

4️⃣ Lowering the temperature intelligently

Lowering the heating slightly, without sacrificing comfort, remains one of the most effective levers:

16-17 °C at night,
14–15°C during extended absences.

These adjustments deliver real savings while maintaining stable comfort.

💡 On average, –1°C = –7% energy consumed.

5️⃣ Measuring, tracking, and adjusting continuously

Beyond the initial actions and settings, performance comes down to monitoring.

Measuring temperatures, identifying drifts, and adjusting continuously helps avoid overconsumption and ensures consistent comfort throughout the winter.
