- TES Energy Facades, prefabricated with cellulose insulation added to existing outside walls, U-wall 0,12 W/m²K. Painted timber windows with triple glazing, U-window 0,9 W/m²K and outside solar control fixtures.
- The roof consists of visible timber beam construction, highly insulated with U-roof 0.11 W/m²K and greening on top. Accessible terraces and thermal solar collectors occupy the whole surface area.
- Central (residual) heating system (CHP combined heat + power, planned before: wood pellet boiler plant), two central heat storage tanks (20 m3) with dual piping system and fresh hot water substations.
- Space heating and domestic hot water assisted by two solar thermal collector systems (208 m²) over green roofs, (solar photovoltaic system proportionally provided over green roofs of building phase 2).
- Controlled ventilation of flats (fresh and waste air) with heat recovery, distributed system for flats (facilitated fire safety, lower costs), centralised in the new building for the district office and habitations.

- STEP 1- roof insulation – placing 30 cm. glass wool insulation on the top of the lower slab of the ventilated double roof.
- STEP 2 – mounting 20 cm EPS with graphite insulation on the walls, reduction of the radiator dimensions, improving the airtightness layer, implementation of the ventilation with heat recovery systems.
- STEP 3 – External underground wall insulation, perimeter insulation, insulation above the ground floor slab in the gym.
- STEP 5 – Replacement of windows: the PVC windows will be replaced in 10 years, when they will be 20 years old. The aluminum windows will be replaced in 20 years, when they will be 30 years old.
- STEP 6 – Implementation of Renewable Energy Sources (Photovoltaic panels)

Energy as a service:
- OSS provided as a complementary business (e.g. by utilities, insurances)
- OSS provided by joint venture of retailers with industry and contractors
- OSS provided by SME contractors’ cluster cooperation
- OSS with home-based financing

While the central aspects of the renovation journey are replicable on most European markets, the model must be adapted to the local context. Applying a similar model in other countries will require a greater focus on quality assurance and an integration of financial support into the model. In Denmark, quality assurance is heavily regulated, including guarantees for the building owners. A more comprehensive quality and compliance scheme is required on most of the other European markets. Furthermore, the available financial subsidy scheme for energy renovations in Denmark is modest and rarely decisive for the building owners’ decision to invest. In countries with substantial public support schemes for energy renovations, this can be incorporated into the business model. Key factors for replication are:
- Use digital solutions to bring added value to the end-users: BetterHome shows that digital solutions can help the construction industry become more consumer-centric and service oriented. Moreover, with the use of innovative digital tools, building professionals can provide a smoother process, for themselves and for the building owner. Aligning with existing stakeholders on the market, including banks and mortgage providers, creates a constructive win-win situation.
- Structure the supply-side: The success of the home-owner-centric business model can be explained by the advanced service-oriented role of the installers. BetterHome trains and guides the installers on how to approach the home-owner, from the first contact to the finalisation of the process. In support, BetterHome also simplifies and structures the renovation process for the installer, through supportive and innovative digital tools, enabling a better evolution for all involved.
- Build awareness for the end-users: Training the installers in order to sell the broader picture, including benefits (e.g. low interest rates, increase in property value, improvements to health of their children and comfort, as well as climate and environmental benefits). The installer is not just replacing the old building elements, but creating a better living environment.
- Safeguard the good reputation: In Denmark, the four companies behind BetterHome are highly respected and associated with quality. Through the cooperation in BetterHome, the companies have worked together to also raise the reputation of the installers.

The step-by-step approach is probably the most likely to be replicated as it minimises the main obstacle to the process of energy renovation of buildings, i.e. the high initial investment. It is the approach that is most suitable for small investors with a prudent attitude, who aim to improve their living conditions and who do not immediately seek a significant increase in property value. The main advantage lies in the possibility to check, after each intervention, the benefits in terms of comfort and energy savings, splitting the risk between smaller investments, as well as keeping the possibility to make corrections in the course of future interventions. The important elements for the success of this business model are:
- Technical know-how of the OSS consultants who advise clients:The interventions carried out in the early stages will have to be compatible with the interventions planned in the future, possibly avoiding unnecessary redundancies, and therefore the allocation of costs in interventions that will not generate savings.
- High percentage of dwellings occupied by owners: Statistically, homeowners are more likely to carry out improvement works.
- Cumulation of incentives over time: In order not to decrease the interventions after the first one, it is essential that the incentives accrued during the various interventions are compatible and cumulative.
- Acceptable level of income and possibility to take advantage of incentives provided as tax deduction: As highlighted by Ameli & Brandt, 2015 the level of income is one of the parameters most closely related to the probability of investing in energy efficiency. Obviously, it has to be weighed against the cost of living, energy and, above all, the average cost of investment.
