Byggnadsintegrerad energilagring och elektromobilitet för flexibla EC

Syntester studie av BESS och EV i EC
Energy community concept map

Denna syntesstudie kartlägger kunskapsläget kring batterienergilagringssystem (BESS) och elfordon (EV) i energigemenskaper, med särskilt fokus på svensk relevans.

Studien har systematiskt granskat 218 vetenskapligt granskade publikationer (2016–2025) och kombinerat traditionell evidenssyntes med NLP-baserad textutvinning, ämnesmodellering och strukturerad taggning över tekniska, ekonomiska, sociala och styrningsrelaterade dimensioner. Syftet var att identifiera vad som fungerar, var kunskapsluckorna finns, och hur Sverige kan påskynda integreringen av energilagring och elektromobilitet i byggnader inom flexibla energigemenskaper.

Granskningen visar ett snabbt växande men ojämnt forskningsfält: publikationerna ökade kraftigt efter 2019; forskningen är huvudsakligen inriktad på kvartersnivå; och kombinationer av solceller (PV) och batterier dominerar, medan integrerade lösningar med EV, sektorkoppling och verklig prestanda fortfarande är begränsade. Sverige är underrepresenterat i litteraturen (~4 % av artiklarna), men utmärker sig genom starkare fokus på PV/EV-integration samt policy, reglering och social acceptans – styrkor som kan användas för att gå från modellering till verkligt genomförbara och rättvisa implementationer

Centrala resultat

  • Snabbt växande forskningsfält: Energiforskning inom energigemenskaper har ökat kraftigt sedan 2019, men fokuserar i stor utsträckning på PV–BESS på kvartersnivå. Integrerade el–värme–mobilitetslösningar och samverkan mellan flera aktörer är fortfarande sällsynta.
  • Metodologisk slagsida: Scenarioanalys och optimeringsmodeller (särskilt MILP/LP) dominerar, medan empirisk validering, långtidsstudier och öppna datamängder är bristfälliga.
  • Begränsad användning av EV som flexibilitetsresurs: EV modelleras ofta som belastningar snarare än som kontrollerbara tillgångar (smart laddning, V2B/V2G), vilket innebär att potentiella värdeskapande möjligheter förbises.
  • Obalans inom ESG-aspekter: Miljödimensionen får ofta förtur, medan social rättvisa, demokratisk styrning och praktiska regleringsfrågor behandlas mer sporadiskt, vilket riskerar ojämlika utfall och genomförbarhetsproblem.
  • Sverige i fokus: Endast nio artiklar (≈4,1 %) behandlar Sverige explicit, men med relativt högre fokus på PV/EV, policy/reglering och social acceptans. Däremot är integration av värme och prosument-/transitionsstudier mindre framträdande

Identifierade möjligheter

  • Samschemalägg BESS och EV: Kombinera gemensamma batterier med smart laddning och V2B/V2G för att möjliggöra effekttoppskapning, tidsmässig arbitrage och stödtjänster på byggnads- och kvartersnivå.
  • Utnyttja sektorkoppling: Använd Sveriges fjärrvärmesystem och byggnadsbestånd för att integrera PV+BESS+värmepumpar/termisk lagring samt absorbera överskottsproduktion (t.ex. vid negativa elpriser).
  • Pilotprojekt med rik evidens: Gå från simulationsdrivna studier till uppföljda demonstrationer med öppna data, standardiserade nyckeltal och flerårig rapportering om prestanda, användarbeteenden och degradering.
  • Rättvisa som designprincip: Inför styrmodeller, kostnads-/nyttodelning och skydd för hyresgäster/låginkomsthushåll från början, för att bygga långsiktig social acceptans och legitimitet.

From Strategy to Action: How Husqvarna Construction is Exploring the Potential of Remanufacturing

Dismantled power cutter Husqvarna Construction

Giving used products a new life is not only a sustainable solution—it can also make strong business sense. Join Husqvarna Construction on its journey towards a more circular business model.

“We see both environmental and economic benefits in reintroducing products to the market,” says Adam Björk, Sustainability Director at Husqvarna Construction.

A Sector with Circular Potential

The construction industry generates 35% of all waste in the EU and accounts for over 20% of Sweden’s carbon emissions—while turning over more than SEK 1,100 billion annually in Sweden alone. In 2020, Sweden produced 14.6 million tonnes of construction and demolition waste.

At the same time, construction equipment contains valuable materials and components that can outlive the product as a whole. More and more manufacturers are starting to recognise the value of these resources.

“Data shows that remanufacturing can significantly reduce climate impact compared to producing new components. For some technical parts, the savings can be as high as 8,000 kg CO₂ per unit. Even smaller components offer clear environmental gains—both per kilo and per finished product,” says Hanna Lindén, researcher and project manager at RISE.

Sustainovate – Strategy that Demands Innovation

Part of the Husqvarna Group, Husqvarna Construction develops professional equipment for the construction industry—such as power cutters, drilling systems and demolition robots. Remanufacturing is a key component of the company’s sustainability strategy, Sustainovate, where circularity is one of three core pillars.

By repairing and remanufacturing products, the company reduces resource consumption and brings valuable materials back into circulation. But turning ideas into action takes both knowledge and collaboration—something a joint project, led in part by RISE, has helped support.

“The project gave us new perspectives and strengthened our belief in the potential of remanufacturing. It’s been incredibly valuable to share experiences with other companies and researchers,” says Adam Björk.

Reverse Logistics – A Key to Circularity

With a broad product portfolio and many different machine types, remanufacturing is a complex process. It requires knowledge development, standardisation, documentation—and also practical solutions for quality assurance, operational adjustments, and above all, reverse logistics, the ability to retrieve products after use.

We’re just at the beginning of our journey, but the potential is clear—both in terms of climate impact and business value.

Insights for Other Manufacturers

Husqvarna Construction’s work offers valuable lessons for other companies looking to transition to more circular business models. Hanna Lindén at RISE highlights a few success factors:

  • Map product flows – Understand where products go after use.
  • Identify potential – Focus on products with high residual value and significant environmental impact.
  • Engage the whole organisation – Design, procurement, service and marketing must all be involved from the start.
  • Collaborate – Shared learning across industries creates both speed and depth.

Shared Learning as a Driver of Change

During a workshop within the project, participants worked hands-on with product disassembly alongside other companies and researchers. According to Adam Björk, this was a crucial piece of the puzzle:

“Working together created both concrete solutions and new perspectives. We were able to identify shared challenges and explore possible paths forward.”

Next Steps – From Pilot to Scale

To make remanufacturing profitable and scalable, several changes are needed. Husqvarna Construction highlights a few key areas:

  • Business models that support remanufacturing
  • Product designs that facilitate disassembly and repair
  • Stronger collaborations across the value chain
  • Increased demand through procurement and clearer regulations

“We believe remanufacturing will play an increasingly important role—both as a business strategy and in meeting market and customer expectations. We’re now using what we’ve learned to further adapt our products and processes,” says Adam Björk.

At the same time, the company is exploring other circular solutions, such as within battery systems. The focus now is on scaling up activities, building internal expertise, and expanding the offering.

“We’ve only just begun our remanufacturing journey, but the potential is clear—both for the climate and for the business,” Adam concludes.

What is Remanufacturing?

Remanufacturing is the process of restoring a used product to the same (or better) performance and quality as a new one. Unlike simple repairs or refurbishing:

  • The product is carefully disassembled to separate all components.
  • Each component is inspected and evaluated to ensure its condition.
  • Worn or outdated parts are replaced with new or upgraded components.
  • The reassembled component is tested to verify its functionality.
  • The final component often comes with the same warranty as a new one to ensure quality.

Remanufacturing is a technically advanced, resource-efficient method with strong potential to reduce both climate impact and material use—especially in industries with complex, material-intensive products.

In some cases, the product is reassembled in its original form, but remanufactured components can also be used in other products.

Innovating Remanufacturing is a project within the Net Zero Industry – Impact Innovation programme, funded by Vinnova, Formas and the Swedish Energy Agency. The aim is to strengthen remanufacturing in Swedish industry through new ideas, exploratory approaches and increased collaboration.

The project is led by RISE in collaboration with Linköping University and SuPr – the Swedish national node for sustainable production. Through disassembly, expert knowledge and advanced technologies, the partners explore innovative methods and share valuable insights.

Industry partners such as Husqvarna Construction, ROL Group, Inrego, Skanska Rental and Dandent contribute with their experience and develop their capabilities in remanufacturing – with the long-term ambition of a more circular and sustainable future.

Sealants have a wide range of uses; they must be able to be flexible and durable in varying environments.

Name of service (page headline, shown in promos – maximum of 70 characters incl. spaces): The importance of testing flexible sealants and joint compounds Lead (include SEO-words and the main benefits for your target groups. Stick to one paragraph, maximum 2-3 sentences):

Flexible sealants and joint sealants play a crucial role in building and construction projects. They ensure that joints are tight, protect against moisture ingress and maintain the durability of the building over time. The consequences of using a joint sealant with the wrong properties can be enormously costly.

Purpose/Benefit:

The importance of testing flexible sealants and joint compounds

By carrying out standardized tests, the performance of the sealant can be assessed and it can be ensured that it can withstand stresses such as temperature variations, mechanical loads and environmental influences. 

Without tests, there is a risk of cracking, weakened adhesion and, in the worst case, leakage that can cause damage to the building. Common test methods include creep and elasticity tests as well as determination of adhesion and durability over time. 

By following international standards, such as ISO 11600, it can be ensured that the sealant meets both functional and aesthetic requirements.

Method (what/which methods are used to perform the service):

With a wide range of equipment and several years of expertise, we can perform a variety of testing methods, all depending on the customer's needs, both standardized and specially developed methods for damage investigations.

Center for Quality Assured Reuse in the Construction Sector

construction site

Uncertainty about quality, traceability and applicable regulations means that reuse in the construction and real estate industry is often rejected - despite great potential to contribute to increased resource efficiency and significant climate benefits. RISE acts as a national knowledge node and collaboration platform, where construction actors gain rapid access to expertise along the entire reuse chain - from material testing and certification to requirement setting and business development.

New legislation and ambitious climate targets mean that the construction and real estate sector is facing a major transition. Reuse is an important part of this transition, but without clear guidelines on how to handle and assess reclaimed materials, it will be difficult to integrate reuse into the construction process. At the same time, there is growing pressure from clients, legislation and society to change. Without a safe and quality-assured way of working with reuse, we lose both environmental benefits and competitiveness.

Services, testing, and certification

RISE offers comprehensive support for reuse in the construction sector – from inventory to quality assurance and business development. Our services include:

Projects

RISE runs and participates in development projects that promote sustainable construction – from concept and pilot to implementation and dissemination. Some projects in the field of reuse are:

RISE offers knowledge-enhancing initiatives in collaboration with industry players. We promote knowledge and dialogue within sustainable construction and tailor the content to the needs of the target group. Our initiatives include:

  • Workshops on reuse
  • Roundtable discussions
  • Presentations at seminars and conferences
  • Foresight analyses

Case study

Case study: Reuse of hollow concrete slabs from Ikea Kållered

When the old Ikea store in Kållered outside Gothenburg was demolished, a unique opportunity arose to test the large-scale reuse of prestressed concrete elements. In close collaboration between RISE, NCC, and Framtiden Byggutveckling, around 3,000 square meters of hollow concrete slabs (HD/F) were dismantled, quality assured, and given new life in the Kvarteret Återbruket residential district in Gothenburg.

Results and lessons learned

  • Dismantling and reassembly went faster than planned.
  • Lifespan assessment: up to 224 years remaining in a dry environment.
  • Climate benefit: approximately 37 kg CO₂e/BTA saved compared to new construction.
  • Economics benefit from modular design and minimal processing requirements.
  • The project has laid the foundation for a Swedish methodology that could become standard.

Fire gas analysis using the steady-state tube furnace

Name of service (page headline, shown in promos – maximum of 70 characters incl. spaces): Fire gas analysis using the steady-state tube furnace Lead (include SEO-words and the main benefits for your target groups. Stick to one paragraph, maximum 2-3 sentences):

ISO/TS 19700 - Controlled equivalence ratio method for the determination of hazardous components of fire effluents – Steady-state tube furnace

Purpose/Benefit:

The technical specification ISO/TS 19700 describes testing using a steady-state tube furnace (SSTF). The sample is slowly feed into the oven and as new material enters the combustion zone, there will be a continuously burning of the material in a steady state.

Method (what/which methods are used to perform the service):

The combustion conditions are established by feeding the sample material into the furnace together with primary air for combustion. The combination of the material feeding rate, the primary air flow rate, and the furnace temperature decides the combustion conditions.

The fire stages replicated using the steady-state furnace are:

  • Fire stage 1b – oxidative pyrolysis (350 °C);
  • Fire stage 2 – well-ventilated flaming fires (650 °C);
  • Fire stage 3a – small vitiated fires in closed or poorly ventilated compartments (650 °C);
  • Fire stage 3b – post-flashover fires in open compartments (825 °C).

The nominal loading of the sample according to ISO/TS 19700 is 25 mg combustible material/mm with a feeding rate of 40 mm/min. The primary air flow is usually 10 l/min for well-ventilated flaming combustion, resulting in a material/air ratio of 100 mg combustible material/l air.

The smoke and gases are collected in a mixing chamber at the end of the furnace. The gas is mixed with secondary air (total flowrate is 50 l/min) and then collected for gas analysis according to ISO 19702 (FTIR) or any method provided in ISO 19701.

Delivery (what does the client get after performed service – e.g. a report, certificate etc.):

A test report, in Swedish or English, is deliverd with the test results after testing.

Functional testing of waterproofing systems for wet areas 2025

The waterproofing project 2025
Functional testing of waterproofing systems

RISE Research Institutes of Sweden has once again been entrusted by LF Research Foundation to conduct a research project on the function of waterproofing systems intended for use behind ceramic tiles in wet areas. This research project is a repetition of previously conducted projects spanning a long period of 15 years.

Projektledare
Completed
Construction
Not applicable
6 månader
Division: Do not use - Division Built Environment

This time, only a smaller number, namely eight, waterproofing systems have been investigated.

Summery of the results

  • Two structures showed no leaks at the end of the test, which corresponds to 25%.
  • Six structures showed leaks at various locations at the end of the test, which corresponds to 75%. In this investigation, the majority of leaks were located at floor-wall angles.
  • Leaks were noted at penetrations of both large and small drain pipes for two of the structures examined.
  • Only one leak was observed at an internal corner.
  • It is gratifying that none of the waterproofing systems examined showed leaks at floor drains, and no leaks were so extensive that they could be classified as total damage.

The project is carried out using a functional test, which means that the water tightness of the waterproofing membrane, penetrations and joints are examined in the waterproofing construction.

 

Summery of results from the functional tests 2010–2025

A total of 91 tests have been carried out during the period 2010 to 2025, i.e. over 15 years.

Of these, 29 (32%) have been positive, i.e. no leaks have been observed at the end of the test.

Negative results, leaks in some form, have been obtained in 62 (68%) of the tests carried out.

The conclusion that can be drawn from the historical review is that the results have improved over time. Overall, however, it must be concluded that the industry should be able to perform better.

The safety margin is obviously quite low or, for some, waterproofing systems completely non-existent.

Therefore, we believe that there is every reason to continue with this type of investigation in order to persuade the industry to further develop its waterproofing structures.

The report from the project can be downloaded here. (Unfortunately, the report is only available in Swedish.)

Reuse of windows, with a focus on technical aspects.

Name of service (page headline, shown in promos – maximum of 70 characters incl. spaces): Reusing of windows Lead (include SEO-words and the main benefits for your target groups. Stick to one paragraph, maximum 2-3 sentences):

Reusing windows poses both technical and economic challenges, but the environmental benefits can be significant. By overcoming these challenges, the construction and real estate sector can contribute to a more sustainable future. One option may be to renovate the window in whole or in part. RISE offers quality assessment and action proposals.

Purpose/Benefit:

Inventory
A stock assessment involves evaluating and documenting the current condition and function of windows. Representative windows are selected to provide an overview of the entire stock.

Mold and Rot Investigation
A laboratory investigation in the microbiology lab involves taking samples from suspected areas and analyzing them to identify the presence of mold and rot. This may include microscopy and other techniques to determine the type and extent of the damage.

Chemical contamination, e.g. PCBs
Sealants and other building materials may contain chemicals such as PCBs (polychlorinated biphenyls). A chemical content investigation involves taking samples and analyzing them to determine the presence and concentration of these substances

Rain and Airtightness
Determining rain and air tightness involves testing the ability of windows to resist water ingress and air leakage.

Status determination of insulating glass
Assessment of the residual function of insulating glass involves evaluating the insulating ability of the glass and any damage or deterioration. This can include measuring the U-value and inspecting the tightness and condition of the glass. Testing the gas filling level. Investigation of the consumption of the desiccant contained in the spacer strips.

Thermal transmittance coefficient U-value
Determining the current U-value means measuring how well a window insulates heat and cold. A lower U-value indicates better insulation and reduced heat loss

Acoustic properties
If there are requirements for acoustic properties, this means evaluating the windows' ability to attenuate sound and reduce noise.

Proposed measures
Based on the above investigations and assessments, proposals for measures are prepared to improve the condition and function of the building's windows. This may include repairs, replacement of materials and other improvement measures.

Method (what/which methods are used to perform the service):

RISE probably has Sweden's largest accreditation from Swedac regarding window testing.

Delivery (what does the client get after performed service – e.g. a report, certificate etc.):

A completed assignment is usually reported in a written report.

The impact of climate change on property values can be extensive, a very large part of the value of properties can be lost. In 2021, the National Board of Housing (Boverket) showed in a literature study that property values can be affected by SEK 96-160 billion from flooding alone. Similar problems are described throughout Europe. At the same time, many of the risks that exist can be prevented or reduced with relatively small efforts if they are identified in time and there are incentives to do the right thing. Property owners, banks, insurance companies and many others need better knowledge of climate-related risks.

Recently entered into force EU regulations such as sustainability accounting rules and classifications of sustainable investments have a strong impact on the industry's need for data at the individual property level. In response to new regulations and to raise awareness of the risks that climate change poses to our building stock, pressure has rapidly built up for the need to act, while the need for synergy is great.

In response to new regulations and to increase awareness of the risks that climate change poses to our building stock, RISE conducted a feasibility study, funded by Vinnova, in 2021-2022 on a standardized assessment of climate risks in real estate called the Climate Resilience Declaration (CRC). The idea of CRC is to eventually develop a model with classification of buildings. For CRC, the feasibility study showed that there was a need for a screening tool as a first step towards full implementation. For this to be possible, currently not yet compiled data on Sweden's buildings is needed.

This project lays the foundation for this screening tool, but regardless of whether a system with CRC is introduced or not, the project also lays the foundation for increased digitalization, new information structures and information flows to find cost-effective measures for the existing and future building stock to be adapted to a future climate.
