Konferensbidrag (refereegranskat)abstract
- In Nordic countries significant primary energy efficiency potential exists in houses built before 1980. These old houses need to be renovated, which provides an opportunity for implementation of energy efficiency measures. However, there are several economic and market barriers and the renovation market are dominated by handicraft-based individual solutions. In this project we analyze the opportunities for implementation of one-stop-shop business models where an overall contractor offers full-service renovation packages including consulting, independent energy audit, renovation work, follow-up (independent quality control and commissioning) and financing.A comparative assessment of emerging business models shows that different types of actors (renovation company, insulation company, energy utility, building product warehouse) can provide such a service. Financing is included in some models. There are differences in how customers are contacted, while the similarities are more on how the service is provided. A main challenge is how to secure independent advising and there is there is uncertainty over who will be responsible for guarantee of the renovation work if the service provider goes bankrupt.Even though there is strong business potential for one-stop-shop energy renovation concept, still it has been somewhat difficult to start or run such a business. Various options to overcome the barriers to promote energy efficient renovation of detached houses are discussed.

One-stop-shop service for sustainable renovation of single family house : Summary Report
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The Nordic project “Successful Sustainable Renovation Business for Single-Family Houses (SuccessFamilies)”, with participants from Denmark, Finland, Norway and Sweden, deals with development of business models for full service energy efficient renovation of detached houses in Nordic countries. The background to this project is that the majority of these houses are more than 30 years old and need to be renovated, which provides opportunity for implementation of energy efficiency measures. The renovation market is dominated by handicraft-based individual solutions. There is a need for onestop-shop business models where an overall contractor offers full-service renovation packages including consulting, independent energy audit, renovation work, independent quality control and commissioning, and financing. There is a significant business potential for such a model as the volume of renovation market for single-family houses can reach hundreds of million Euros per year in each Nordic country. The project team analysed emerging business models to offer full-service renovation packages in the Nordic countries. A comparative assessment shows that different types of actors (renovation company, insulation company, energy utility, building product warehouse) can provide such a service. There are differences in how customers are contacted, while the similarities are more on how the service is provided. A main challenge is how to secure independent advising. Even though there is strong business potential for one-stop-shop energy renovation concept, still it has been somewhat difficult to start or run such a business. Various options to overcome the barriers to promote energy efficient renovation of detached houses are discussed in the final report.

Existing sustainable renovation concepts, Deliverable D1.1 : Successful Sustainable Renovation Business for Single-Family Houses - SuccessFamilies

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The Nordic single-family house renovation market is dominated by a craftsman based approach with individual solutions, traditional warehouses ”do-it-yourself-shops” and some actors marketing single products. To speed up the implementation of sustainable renovation of single-family houses there is a great need for full-service packages including consulting, contract work, follow-up, financing and operation and maintenance. There are few Nordic examples of such service models for renovation of single-family houses which entered the market recently. The success of these concepts is yet to be evaluated.One successful full-service package described in the report is a campaign by an energy company in Sweden who convinced 78% of 456 owners of houses with resistance heaters to connect to its biomass based district heating network. The campaign was successful because of its package offer and information provision with emphasis on economic aspects and functional reliability.The existing technical renovation concepts, typically focussing on application of only a few of the available technical solutions, have not been successful in realizing large scale energy efficiency gains. Renovation of single-family houses might be carried out based on design solutions with good combinations of the possible range of technical solutions including e.g. “passive (insulation) measures” and “solar measures” in order to reach a low primary energy level. Key aspects of reaching a low primary energy level in connection with renovation are described in the form of typical energy renovation measures and technical principles of low energy renovation including recommended extent of measures.Full service and technical renovation concepts should make it easy, simple and secure for the consumer to invest in a low energy renovation of their house. The building sector needs easy to use knowledge and initiatives which ensures that they can offer solutions which fulfil the demand for quality, economy and a simple process. To speed up the implementation of sustainable renovation of single-family houses, society needs to stimulate the process including better incentives structures, e.g. increased tax on energy and/or subsidy programmes. Combined with an outlook for rising global energy prices, sustainable renovation of single-family houses then has the potential to become an important market area in the future.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Due to the introduction of low energy standards for new houses as minimum requirements, rising energy prices and generally more focus on energy performance, there is a need for farreaching energy efficiency improvements in connection with renovation if existing singlefamily houses in the Nordic countries are to have competitive power compared to new houses on the future housing market. If the market is able to explain this to the homeowners there is an open market with undreamt-of possibilities. Good technical solutions exist but need to be combined based on the full range of (standard) solutions in order to reach the low primary energy level of new houses. The typical single-family houses identified to have large primary energy saving potential almost descend from the same time period in each Nordic country. The first segment is houses built in large numbers in the 1960 and 1970 before tightening of the insulation standards in the building codes in the late 1970’s due to the oil crisis. The second segment is houses built before 1945 (except for Finland) where a large part of them has been renovated, but energy renovation of those houses today would still account for a large energy saving. The third segment is type houses from the post-war period in Finland. A complete energy efficient renovation of a typical house include post-insulation and sealing of the buildings envelope - roof/ceiling, façade, windows/doors and foundation and maybe slab on ground - installation of a mechanical ventilation system with high efficiency heat recovery and low electricity use and if not already there, an energy efficient heating system based on district heating, heat pump etc. This package of technical solutions can be carried out during an overall or step wise planned renovation dependent on the condition of the house, the financial possibilities of the homeowner etc. Calculation of packages of energy efficient renovation solutions targeted the three segments of houses show that primary energy use and heating bill can be reduced with up to about 75% or a factor 4 corresponding to the level of a new house or better. It seems that the passive house level can not quite be reached with standard solutions. They require that more ambitious measures are applied. The total investment needed to reduce the heating bill by a factor 4 including replacement of e.g. roof and windows is up to EUR 100,000. It is generally difficult to obtain an economy in balance in the sense that the annual payment on a cheap loan, e.g. mortgage refinancing, to finance the investment is not fully offset by the expected annual energy savings. Since, the cost of energy measures today may not correspond to the increased market value of the house, it is important to find mechanisms so that the total cost of the energy investments in the future is reflected as an increased value of the house. But with due regard to all the non-energy benefits, such as better and healthier indoor environment and comfort, and less dependence on expected future higher energy prices, energy efficient renovation will probably still be attractive for the average homeowner. One-stop-shops in the form of full-service providers of energy efficient renovation of singlefamily house are missing in the Nordic countries. This service is vital to open up the market. A one-stop-shop could be seen as a possibility to make it easy for the homeowner to comply with possible future requirements to realize far-reaching energy savings in connection with extensive renovations, provided that the building sector offers the solutions. Homeowners need someone to take care of all relevant steps necessary for the renovation of the house including quotation for the work, financing and management of the contract work. An ideal full-service concept in five phases is proposed, going from initial evaluation of the house, to extensive analyses, proposal for package solutions, coordinated execution and operation and finally management of the house after renovation.
