Description

In Europe, the push for energy-efficient housing has led to widespread use of financial incentives such as grants, loans, and tax rebates to encourage homeowners to undertake retrofits. These measures aim to reduce energy consumption and improve the environmental performance of residential buildings. Governments across the continent have adopted various programs to support these efforts, offering significant financial aid to make energy-saving improvements more accessible to homeowners. In addition to subsidies, some countries implement energy taxes to further promote efficiency and fund sustainability initiatives. At the European Union level, comprehensive strategies are being developed to enhance the energy efficiency of buildings, including proposals for new regulatory frameworks and financial incentives. This multi-faceted approach reflects a growing recognition of the importance of sustainable housing in achieving broader environmental and economic goals.

Subsidisation of housing retrofit, through grants and loans, as well as tax rebates are commonly used across Europe to incentivise the energy-efficient retrofit of the housing stock (Castellazzi et al., 2019). Following this trend, the Dutch government has put in place a series of grants and subsidised loans to incentivise retrofit. First, the “Subsidie Energiebesparing Eigen Huis” is a grant programme covering up to 50% of retrofit costs when at least two energy-saving measures improving EPC levels have been implemented. Dutch homeowners can also apply for the Investment Grant for Sustainable Energy Savings (ISDE) in the case of single measures such as solar boilers or heat pumps (Ministry of Economic Affairs and Climate Policy, 2019). Since 2022, 0% interest loans are also available to low-income households from the National Heat Fund.

On the stick side of retrofit incentivation, the Netherlands implements a regressive form of carbon taxation on individual households (Maier & Ricci, 2024). Research by the Dutch National Bank has also alluded to the strong impact of energy taxation on lower incomes and the inelasticity of energy consumption. Havlinova et al. (2022) have found that the introduction of stronger forms of energy taxation in heated energy markets can impinge on lower incomes resulting in regressive distributional impacts. At the EU level, the Renovation Wave is actively promoting this approach to housing retrofit through its proposal to include buildings in the Emissions Trading Scheme (ETS) together with the implementation of retrofit subsidies(2003/87/EC). As a result, while owner-occupied housing is undertaxed, the tax burden on energy consumption at the household level is poised to increase.

Retrofit subsidies usually come to join fiscal systems favouring owner occupation. These forms of direct subsidisation of housing retrofit coalesce with increases in the fiscal burden on energy consumption. According to Haffner & Heylen (2011), the housing taxation structure favours owner-occupation with a mortgage through large deductions in income tax. In the Netherlands, imputed rent, the main form of housing taxation is calculated on the basis of a notional rent value and then added onto box 1 which comprises labour income. All other income from investments is taxed under box 3 at a different rate. Haffner & Heylen (2011) have analysed the lack of tax neutrality in this system and propose to include the taxation of housing assets under box 3 as a tax-neutral benchmark. In the context of housing retrofit, the favourable fiscal treatment of homeownership comes to join generous subsidies for owner-occupied housing retrofit with no maximum income threshold offered by the Dutch government. A green tax  is a viable alternative to incentivise retrofit in a more progressive manner.

The Dutch approach to incentivising housing retrofits exemplifies a broader European commitment to enhancing energy efficiency through a combination of financial incentives and regulatory measures. While generous subsidies and tax incentives significantly benefit homeowners, particularly those with mortgages, the regressive nature of energy taxation presents challenges for lower-income households.

Research indicates that increased energy taxation disproportionately impacts these households, underscoring the need for more progressive solutions. The EU’s Retrofit Wave, along with the proposed inclusion of buildings in the ETS, reflects an ongoing effort to balance these measures. In the context of housing retrofits, a shift towards green taxes could provide a more equitable framework, ensuring that the financial burden and benefits of energy-efficient improvements are more evenly distributed across different income groups.

Alignment with project research areas

The Dutch government’s approach to incentivizing energy-efficient retrofits through subsidies, grants, and low-interest loans is a clear example of policy in action. The implementation of a regressive carbon tax and the proposed green tax also demonstrate how policy can be used to drive sustainable practices and behaviours. These policies align with RE-DWELL’s focus on developing and implementing effective policies for affordable and sustainable housing.

The energy-efficient retrofits encouraged by the Dutch government’s subsidies and grants involve the design of sustainable housing solutions. These retrofits may include the installation of solar boilers and heat pumps, which contribute to the design of homes that are more energy-efficient and environmentally friendly. This aligns with RE-DWELL’s emphasis on sustainable design in the housing sector.

The Dutch housing policies require active participation from homeowners, who must apply for grants and loans, and undertake energy-saving measures in their homes. This highlights the importance of public participation in achieving sustainability goals, a key aspect of the RE-DWELL project. However, the potential impact of these policies on lower-income households underscores the need for inclusive participation, ensuring that all segments of society can benefit from sustainable housing initiatives.

Alignment with SDGs

The Dutch housing retrofit subsidies and taxation policies align with several Sustainable Development Goals (SDGs). Firstly, they contribute to SDG 7, Affordable and Clean Energy, by promoting energy-efficient retrofits and the use of sustainable energy sources like solar boilers and heat pumps. Secondly, the regressive carbon tax and the proposed green tax relate to SDG 13, Climate Action, as they aim to reduce greenhouse gas emissions.

However, the impact of these policies on lower-income households raises concerns about SDG 10, Reduced Inequalities. The regressive nature of the carbon tax and the potential for retrofit subsidies to favour homeowners may exacerbate income disparities. Thus, achieving a balance between environmental sustainability and social equity is crucial.

Affordability is defined as the state of being cheap enough for people to be able to buy (Combley, 2011). Applied to housing, affordability, housing unaffordability and the mounting housing affordability crisis, are concepts that have come to the fore, especially in the contexts of free-market economies and housing systems led by private initiatives, due to the spiralling house prices that residents of major urban agglomerations across the world have experienced in recent years (Galster & Ok Lee, 2021). Notwithstanding, the seeming simplicity of the concept, the definition of housing affordability can vary depending on the context and approach to the issue, rendering its applicability in practice difficult. Likewise, its measurement implies a multidimensional and multi-disciplinary lens (Haffner & Hulse, 2021). One definition widely referred to of housing affordability is the one provided by Maclennan and Williams (1990, p.9): “‘Affordability’ is concerned with securing some given standard of housing (or different standards) at a price or a rent which does not impose, in the eyes of some third party (usually government) an unreasonable burden on household incomes”. Hence, the maximum expenditure a household should pay for housing is no more than 30% of its income (Paris, 2006). Otherwise, housing is deemed unaffordable. This measure of affordability reduces a complex issue to a simple calculation of the rent-to-income ratio or house-price-to-income ratio. In reality, a plethora of variables can affect affordability and should be considered when assessing it holistically, especially when judging what is acceptable or not in the context of specific individual and societal norms (see Haffner & Hulse, 2021; Hancock, 1993). Other approaches to measure housing affordability consider how much ‘non-housing’ expenditures are unattended after paying for housing. Whether this residual income is not sufficient to adequately cover other household’s needs, then there is an affordability problem (Stone, 2006). These approaches also distinguish between “purchase affordability” (the ability to borrow funds to purchase a house) and “repayment affordability” (the ability to afford housing finance repayments) (Bieri, 2014). Furthermore, housing production and, ultimately affordability, rely upon demand and supply factors that affect both the developers and home buyers. On the supply side, aspects such as the cost of land, high construction costs, stiff land-use regulations, and zoning codes have a crucial role in determining the ultimate price of housing (Paris, 2006). Likewise, on the policy side, insufficient government subsidies and lengthy approval processes may deter smaller developers from embarking on new projects. On the other hand, the demand for affordable housing keeps increasing alongside the prices, which remain high, as a consequence of the, sometimes deliberate incapacity of the construction sector to meet the consumers' needs (Halligan, 2021). Similarly, the difficulty of decreasing household expenditures while increasing incomes exacerbates the unaffordability of housing (Anacker, 2019). In the end, as more recent scholarship has pointed out (see Haffner & Hulse, 2021; Mulliner & Maliene, 2014), the issue of housing affordability has complex implications that go beyond the purely economic or financial ones. The authors argue that it has a direct impact on the quality of life and well-being of the affected and their relationship with the city, and thus, it requires a multidimensional assessment. Urban and spatial inequalities in the access to city services and resources, gentrification, segregation, fuel and commuting poverty, and suburbanisation are amongst its most notorious consequences. Brysch and Czischke, for example, found through a comparative analysis of 16 collaborative housing projects in Europe that affordability was increased by “strategic design decisions and self-organised activities aiming to reduce building costs” (2021, p.18). This demonstrates that there is a great potential for design and urban planning tools and mechanisms to contribute to the generation of innovative solutions to enable housing affordability considering all the dimensions involved, i.e., spatial, urban, social and economic. Examples range from public-private partnerships, new materials and building techniques, alternative housing schemes and tenure models (e.g., cohousing, housing cooperatives, Community Land Trusts, ‘Baugruppen’), to efficient interior design, (e.g., flexible design, design by layers[1]). Considering affordability from a design point of view can activate different levers to catalyse and bring forward housing solutions for cities; and stakeholders such as socially engaged real estate developers, policymakers, and municipal authorities have a decisive stake in creating an adequate environment for fostering, producing and delivering sustainable and affordable housing.   [1] (see Brand, 1995; Schneider & Till, 2007)

Housing is usually deemed unaffordable when it consumes more than a set percentage of a household's monthly income. The Eurostat (2022) and the OECD (Chung et al., 2018) follow this threshold approach and define households overburdened with housing costs as those that spend more than 40% of their disposable income on housing. However, this indicator fails to capture financial hardship, particularly among lower-income households. In fact, lower-income households may be spending less than 40% of their income on housing and yet failing to meet adequate consumption levels for other goods. As a response, the residual income approach ascertains housing (un)affordability by defining a minimum level of consumption for a set of goods according to particular household types. The residual income approach builds on consumption data to define the minimum level of income necessary for a household to survive after housing costs. The main shortcoming of this approach is that relies on subjective measures of what constitutes the necessary minimal expenses for a household. These two definitions of affordability navigate two tensions 1) between housing and other types of consumption and 2) between the individual conceptions of what is affordable and what the government considers to be affordable (Haffner & Hulse, 2021). More recently, scholars have emphasized the multi-faceted nature of affordability to include commuting and transport costs together with energy costs (Haffner & Boumeester, 2010). Other approaches focus on supply-side measures, for instance on the share of the housing stock that a household can afford (Chung et al., 2018). Evolutions in the measurement of affordability bear witness to the complexity of housing systems. Affordability is not only dependent on housing consumption but also on housing supply, particularly in inelastic markets where providers have considerable power, see for example Kunovac & Zilic (2021). At the same time, displacement pressures and rising energy costs in an older and inefficient stock add pressure on households to access affordable housing.

Financial wellbeing is an emerging concept with valyrious definitions, many of which focus on the financial capabilities of individuals. A household's financial wellbeing encompasses its capacity to comfortably meet current and ongoing financial responsibilities, fostering a sense of security about future obligations while enjoying the ability to make life choices (Aubrey et al., 2022). Riitsalu et al. (2023) describe it as "feeling good about one's personal financial situation and being able to afford a desirable lifestyle both now and in the future" (p.2). Brüggen et al. (2017:229) frame it as "the perception of being able to sustain current and anticipated desired living standards and financial freedom." This perception highlights the robust link of financial wellbeing influencing human wellbeing, which is a combination of "feeling good and functioning well" (Ruggeri et al., 2020:1). Other terminologies are used interchangeably to describe financial wellbeing, including financial health, financial resilience, and financial freedom (Riitsalu et al., 2023).     In the UK, the public health sector cares to raise awareness of financial wellbeing due to its impact on households' health and populations' productivity. On their official website page on Financial Wellbeing, they used the definition by The Money and Pension Service (Gov.UK, 2022: online) as follows:   "Feeling secure and in control of your finances, both now and in the future. It's knowing that you can pay the bills today, can deal with the unexpected, and are on track for a healthy financial future."   These explanations and the terminology used, including "afford" and "sustain," underscore the interconnections between financial wellbeing and the vital components of household life. These components encompass mental health, productivity, and pursuing economic sustainability in the present and future. Therefore, a household's financial wellbeing is pressured by various housing-related factors, including the costs of renting or buying and non-housing costs like utility bills and repairs, all of which can affect the household's income.   The issue of rising housing costs directly undermines financial wellbeing. This trend can be attributed to several factors, including increased construction costs, labour shortages, and rising material prices (Brysch & Czischke, 2021). Furthermore, there is a notable shortage in affordable and social housing supply (Emekci, 2021; Gov.UK, 2022). This scarcity is partly due to decreased public investment in new dwellings (Housing Europe, 2021; OECD, 2020). This issue further burdens low-income households who face high private rental costs and a gradual reduction in housing benefits (Tinson & Clair, 2020).   This issue also leads many households to cut back on essential needs. For instance, interviews with social housing residents in Scotland with low to modest incomes revealed a tendency to prioritize rent payments over other necessities, such as food and heating (Garnham et al., 2022). Similarly, Adabre and Chan (2019), , citing Salvi del Pero et al. (2016), warned that:   "Households who are overburdened by housing cost may cut back on other important needs such as health care and diet. Besides, in the medium term, households may trade-off costs for lower quality housing such as smaller size of rooms and housing in poorer locations which lack better access to education and other social amenities. The latter has often been cited as the cause of residential segregation."   Another financial burden is non-housing costs involving energy costs for heating (AHC, 2019; Stone et al., 2011). According to Lee et al. (2022), this issue persists, contributing to financial strain and even excess winter deaths in the UK. Poor housing quality raises energy bills (AHC, 2019; Lameira et al., 2022). It presents the risk of considering dwellings as affordable due to local authority support focusing on housing costs alone (Granath Hansson & Lundgren, 2019), regardless of its quality impacting energy bills (OECD, 2020). Social housing residents, particularly the ageing population and those living in poverty are at increased risk of fuel poverty (Tu et al., 2022). Fuel poverty occurs when more than 10% of a household's income goes towards energy consumption for heating (Howden-Chapman et al., 2012).   Looking forward, two factors could continue burdening households’ financial wellbeing. One factor is the fluctuating energy prices that are often increasing, such as the case in the UK (Bolton, 2024). Another factor is the impact of climate change, leading to colder winters and the potential for overheating, increasing energy demand during extreme weather conditions, as warned by the Committee of Climate Change in the UK (Holmes et al., 2019).   Non-housing costs associated with extensive housing repairs can also impact household financial wellbeing, which may arise from several factors. For instance, selecting low-quality construction materials, workforce or equipment to reduce construction costs might lead to increased repair costs over time (Emekci, 2021). Hopkin et al. (2017) highlighted a related issue in England, where new housing defects were believed to be partly attributed to the building industry's prioritization of profitability over customer satisfaction. Another factor could be improper periodic maintenance, potentially accelerating the physical deterioration of the dwelling (Kwon et al., 2020). Additionally, dwellings may fall into disrepair due to unresponsive maintenance services from housing providers, and residents may lack the financial means to cover repair costs themselves (Garnham et al., 2022).     Financial wellbeing is closely tied to household income. Low-income households are particularly vulnerable to being burdened by rising housing costs (Housing Europe, 2021; OECD, 2020), leading to financial insecurity (Hick et al., 2022). In addition, they might suffer housing deprivation due to the increasing housing and non-housing expenses coupled with their declining incomes (Emekci, 2021; Wilson & Barton, 2018). The financial pressure due to low income is further exacerbated if a household member has a disability or severe illness, potentially consuming up to 35% of their income (AHC, 2019). Recently, the COVID-19 pandemic period highlighted households' financial wellbeing vulnerability to housing-related financial challenges (Brandily et al., 2020; Hick et al., 2022; National Housing Federation, 2020). During this period, job losses led to difficulties covering housing and non-housing costs, with a third of low-income social housing residents burdened by housing costs (OECD, 2020).   The issues discussed above on dwellings being of poor quality or unaffordable harm financial wellbeing, leading to residential segregation (Adabre & Chan, 2019; Salvi del Pero et al., 2016) as well as intensifying gaps of social injustice, health injustice, poverty, and fuel poverty (Barker, 2020; Garnham et al., 2022). Without addressing those housing-related issues, many households' financial wellbeing would remain vulnerable to economic insecurity even if they live in housing considered to be "affordable" in terms of rent-to-income ratio.

As a response to the regressiveness of housing taxation and the subsidisation model of housing renovation, (Muellbauer, 2018) has introduced the idea of a Green Land Value Tax (GLVT). The GLVT is composed of two elements, one based on built-up surface and another on unoccupied land. Energy-efficient buildings would pay the same tax as unoccupied land while energy-inefficient ones would pay a proportional increase by energy use. Such tax would create incentives to retrofit and improve the financial viability of increasing densities as the tax burden on built-up surface could be shared by different households in multiple occupation buildings but concentrated on one owner in the case of single-family dwellings. In this regard, the study of policies such as mortgage interest deduction has pointed out how the lack of adequate taxation leads to the overconsumption of owner-occupied housing and increases in house prices (Fatica & Prammer, 2018; Poterba, 1984).   On the one hand, targeting grants at households could incentivise retrofit among low-income homeowners for whom the impact of increased costs could pose affordability problems. On the other hand, increased taxation of energy-inefficient homes could help redistribute housing wealth toward younger homeowners in the most energy-efficient proportions of the stock and incentivise retrofit through increasing housing costs for house- wealthy households. However, the political feasibility of these drastic policy changes remains questionable. Although there is no land value taxation in the Netherlands, the Dutch case remains particularly apposite to test green taxation proposals through imputed rent as done in Fernandez et. al (2024). The Netherlands lacks tax neutrality across tenures and imposes regressive taxes on energy consumption. These renovation incentivising policies result from a consumption interpretation of housing renovation as a one-off expense, not as an investment resulting in the appreciation of a financial asset (Copiello & Donati, 2021). Albeit under-taxing it according to the literature presented before, Dutch fiscal policy treats owner-occupied housing as an asset (Haffner, 2003). Aligning incentives for renovation with the asset interpretation of housing present in fiscal policy opens up paths for a set of green tax tools (Fernandez et. al, 2024). This concept is an excerpt from the article Fernández, A., Haffner, M. & Elsinga, M. Subsidies or green taxes? Evaluating the distributional effects of housing renovation policies among Dutch households. J Hous and the Built Environ (2024). https://doi.org/10.1007/s10901-024-10118-5

Definition: Housing policy Housing policies are usually understood in a narrow manner as social policies targeting housing prices through housing allowances, tax deduction or social housing allocation. This definition takes a different approach and draws from a larger body of economic literature to identify the wider array of policies that impact housing markets. Broadly speaking, housing markets are influenced through fiscal, macroeconomic, prudential and structural policies (Hilbers et al., 2008). This wide range of public policies have clear impacts on housing demand and supply and also usually create synergies between each other. Fiscal policies have a stronger impact on income and costs through taxation and subsidies. One of the main fiscal policies with regard to housing is the mortgage interest deduction which reduces user costs and can produce increases in property prices (Poterba, 1984). Macroeconomic policy regulates the money supply through interest rates. Housing has usually been perceived as a conveyor belt for macroeconomic policy as the expansion of the money supply through low interest rates or quantitative easing has the potential to increase demand during recessions counteracting the procyclical behaviour of financial markets (Muellbauer, 1992). Prudential policies determine the level of risk associated with lending through Loan-to-Value (LTV) and Debt-to-Income (DTI) ratios. The Great Financial Crisis is usually seen as the failure of prudential policy that resulted in the tightening of loans  (Whitehead & Williams, 2017) and  drew renewed attention to housing policy from central banks, policymakers, and economists (Piazzesi et al., 2016). Structural policies regulate housing supply, this includes planning regulations and environmental standards. For example, research from the US has shown that zoning laws can have a relevant impact on housing affordability by constraining supply (Glaeser & Gyourko, 2002). While most research is conducted selectively on each of these policy interventions, there are relevant synergies between policy domains that can be identified. These policies usually work in conjunction with each other: lax prudential policies and favourable home ownership taxation together with low interest rates and tight planning controls can lead to higher property prices. Conversely, constrained lending, brick-and-mortar subsidies and higher interests rates are known to mitigate rising house prices.

Environmental Retrofit Buildings are responsible for approximately 40% of energy consumption and 36% of carbon emissions in the EU (European Commission, 2021). Environmental retrofit, green retrofit or low carbon retrofits of existing homes ais to upgrade housing infrastructure, increase energy efficiency, reduce carbon emissions, tackle fuel poverty, and improve comfort, convenience and aesthetics (Karvonen, 2013). It is widely acknowledged that environmental retrofit should result in a reduction of carbon emissions by at least 60% in order to stabilise atmospheric carbon concentration and mitigate climate change (Fawcett, 2014; Johnston et al., 2005). Worldwide retrofit schemes such as RetrofitWorks, EnerPHit and the EU’s Renovation Wave, use varying metrics to define low carbon retrofit, but their universally adopted focus has been on end-point performance targets (Fawcett, 2014). This fabric-first approach to retrofit prioritises improvements to the building fabric through: increased thermal insulation and airtightness; improving the efficiency of systems such as heating, lighting and electrical appliances; and the installation of renewables such as photovoltaics (Institute for Sustainability & UCL Energy Institute, 2012). The whole-house systems approach to retrofit further considers the interaction between the occupant, the building site, climate, and other elements or components of a building (Institute for Sustainability & UCL Energy Institute, 2012). In this way, the building becomes an energy system with interdependent parts that strongly affect one another, and energy performance is considered a result of the whole system activity. Economic Retrofit From an economic perspective, retrofit costs are one-off expenses that negatively impact homeowners and landlords, but reduce energy costs for occupants over the long run. Investment in housing retrofit, ultimately a form of asset enhancing, produces an energy premium attached to the property. In the case of the rental market, retrofit expenses create a split incentive whereby the landlord incurs the costs but the energy savings are enjoyed by the tenant (Fuerst et al., 2020). The existence of energy premiums has been widely researched across various housing markets following Rosen’s hedonic pricing model. In the UK, the findings of Fuerst et al. (2015) showed the positive effect of energy efficiency over price among home-buyers, with a price increase of about 5% for dwellings rated A/B compared to those rated D. Cerin et al. (2014) offered similar results for Sweden. In the Netherlands, Brounen and Kok (2011), also identified a 3.7% premium for dwellings with A, B or C ratings using a similar technique. Property premiums offer landlords and owners the possibility to capitalise on their  retrofit investment through rent increases or the sale of the property. While property premiums are a way to reconcile          split incentives between landlord and renter, value increases pose questions about long-term affordability of retrofitted units, particularly, as real an expected energy savings post-retrofit have been challenging to reconcile (van den Brom et al., 2019). Social Retrofit A socio-technical approach to retrofit elaborates on the importance of the occupant. To meet the current needs of inhabitants, retrofit must be socially contextualized and comprehended as a result of cultural practices, collective evolution of know-how, regulations, institutionalized procedures, social norms, technologies and products (Bartiaux et al., 2014). This perspective argues that housing is not a technical construction that can be improved in an economically profitable manner without acknowledging that it’s an entity intertwined in people’s lives, in which social and personal meaning are embedded. Consequently, energy efficiency and carbon reduction cannot be seen as a merely technical issue. We should understand and consider the relationship that people have developed in their dwellings, through their everyday routines and habits and their long-term domestic activities (Tjørring & Gausset, 2018). Retrofit strategies and initiatives tend to adhere to a ‘rational choice’ consultation model that encourages individuals to reduce their energy consumption by focusing on the economic savings and environmental benefits through incentive programs, voluntary action and market mechanisms (Karvonen, 2013). This is often criticized as an insufficient and individualist approach, which fails to achieve more widespread systemic changes needed to address the environmental and social challenges of our times (Maller et al., 2012). However, it is important to acknowledge the housing stock as a cultural asset that is embedded in the fabric of everyday lifestyles, communities, and livelihoods (Ravetz, 2008). The rational choice perspective does not consider the different ways that occupants inhabit their homes, how they perceive their consumption, in what ways they interact with the built environment, for what reasons they want to retrofit their houses and which ways make more sense for them, concerning the local context. A community-based approach to domestic retrofit emphasizes the importance of a recursive learning process among experts and occupants to facilitate the co-evolution of the built environment and the communities (Karvonen, 2013). Involving the occupants in the retrofit process and understanding them as “carriers” of social norms, of established routines and know-how, new forms of intervention  can emerge that are experimental, flexible and customized to particular locales (Bartiaux et al., 2014). There is an understanding that reconfiguring socio-technical systems on a broad scale will require the participation of occupants to foment empowerment, ownership, and the collective control of the domestic retrofit (Moloney et al., 2010).

Traditionally the viability of renovation has been assessed through a Discounted Cash-Flow (DCF) analysis of saved energy, which is highly contingent on the discount rate (Copiello & Donati, 2021). However, these authors propose an alternative method that capitalises energy savings into housing value, thereby circumventing the limitations of discounted predicted energy savings, which are already reflected in the property value. They employ an asset-based approach to analyse renovation viability by evaluating costs and benefits in terms of value increases.The value increase of energy-efficient improvements in real estate markets usually takes the form of a green premium identified through different econometric techniques, see for example  Aydin et al. (2020)  for a recent study of property premiums in the Netherlands. To increase the financial viability of renovation, the EU proposes three approaches that have been incorporated differently by Member States (Bertoldi, 2022). First, on the one hand, grants and loans rely on the reduction or complete elimination of upfront costs –“carrot” approach– to encourage renovations (see Eryzhenskiy et al., 2022, for example). Second, the “stick” side of housing renovation incentives draws on mandatory Minimum Energy Performance Standards (MEPSs), which preclude the renting or selling of properties that fall below a certain Energy performance Certificate (EPC) level (Economidou et al., 2020). Third, the European Commission also plans to expand the Emissions Trading Systems (ETS) to encompass buildings before the end of the decade (2003/87/EC). This will likely impact energy costs and increase the viability of energy-efficient renovations (Backe et al., 2023). Fernández, A., Haffner, M. & Elsinga, M. Subsidies or green taxes?
