Might success in Sweden inspire the Finns to reduce energy use in buildnings?

The following is another example of WWF Finland’s Smart Climate Solutions case studies.

Energy efficiency in buildings – low-energy and passive houses spreading in Sweden   

Description of climate policy measure Since 1990 the level of GHG emission from buildings has been reduced by over 70 % inSweden

The overall decrease has primarily been achieved due to a switch from oil to district heating, accompanied in recent years by an increase in heat pumps and pellet solutions. This development has been strongly driven by C02-taxes and high oil prices that have provided a clear price signal but a mixture of accompanying policy measures has also contributed to the high speed of conversions. Sweden has rather low emissions from the electricity and heating sectors but this is more due to choice of primary energy sources than low overall consumption of electricity

The sector of residential buildings and service organizations still consumes 36% of the total energy inSweden

Consequently, in June 2006 the Swedish parliament decided that the energy use in residential buildings and premises should decrease by 20% per heated unit area before 2020. In order to reach this goal, it is clear that more energy efficient buildings must be produced as well as energy efficient improvements must be performed on the existing building stock. One way to reduce the use of energy in buildings is to build passive houses and set corresponding targets for renovations.   Key challenges in implementation and drivers/reasons of success Passive houses do not require any new technology development per se and the key barriers hampering market penetration and growth have been primarily related to lack of coordinated information, knowledgeable passive house construction experts and uncertainty of future energy efficiency requirements. While the overall policy mixture in Sweden (including environmental taxes on electricity and heating oil, construction standards, financial incentives, public procurement and R&D efforts) has provided a sufficient framework for breaking the barriers, the market pull has been created by proactive forerunners from local level, cities, municipalities as well as private citizens and bigger construction companies raising to the challenge. An active dialog (facilitated by the by “Bygga-Bo-dialogen, launched 2003) between communes, construction companies, property owners, banks, insurance companies and the government has been an important part of providing the required knowledge base and coordination for a more sustainable construction and building sector in Sweden.  Assessment of CO2-emission reductions and if available any preliminary estimates of emission reduction costs (euro ton/CO2ekv)

Passive houses have the potential to cut the amount of energy required for heating by some 60% in comparison to existing construction standards for new buildings in Sweden. Depending on the choice of energy for heating, passive houses can consequently contribute to important emission cuts on national level. With regards to reconstruction of the existing building stock, on-going projects indicate that energy consumption can be reduced by over 50% through low-energy renovation solutions.

Presentation of existing estimates concerning ancillary (effects) benefits The international experiences from over 10 000 passive houses built in Germany, 3000 in Austria as well as 1500 in Sweden and Norway indicate that construction costs for passive houses are slightly higher but with good planning can be limited to only some percentages of the total costs. The higher initial investment costs are counterbalanced through lower energy costs in a rather short period of time. On the national level, the lower energy consumption of passive houses contributes to cost-efficient national mitigation efforts. In addition, combined with renewable energy (RE) systems such as solar (PV, active solar water heating) or small biofuel CHP (wood chip, biodiesel, pellet etc) and net metering, the passive houses can turn active – a development already taking place in several forerunner passive house countries.

Preliminary assessment of feasibility and any required modifications for similar policy measures in Finland The international lessons learned provide a good basis for Finland to enter into the low energy and passive house arena. In Finland, a clear and ambitious long-term target is required to provide the right signal for a sustainable building sector, covering both the reconstruction of existing buildings as well as new buildings.  The experiences from Sweden indicate that the market for low-energy and passive houses can rapidly be developed, as long as the right price signals and framework conditions are in place.  An energy efficient reconstruction of the existing building stock in Finland could contribute to energy savings of over 12 TWh, corresponding to cuts in greenhouse gasses of some 3,5  MtCO2 by 2020. 

With regards to new buildings, passive houses in Finland could cut the consumption of heating energy by 75-80% in comparison to existing construction standards. Several on-going national initiatives can be harnessed to guarantee that the required standards are set high enough (step wise low-energy, passive house and zero-energy), the country specific knowledge base is efficiently created and information nationally shared. Municipalities can take a lead role in creating sustainable and attractive living conditions for their citizens and the private sector. It is crucial that the forthcoming demonstration experiences in Finland are systematically analyzed, the results monitored and consequently education for the lacking construction expertise tailored and provided.

In Finland, due to different climate conditions and geographical location, the limit is around 20-30 kWh/m2/year. According to the International Energy Agency, existing buildings are responsible for over 40% of the world’s total primary energy consumption and account for 24% of world carbon dioxide (CO2) emissions.

When your system is net metered, power that the system generates can be used first by your house loads, and then (if there is extra power) fed back into the utility grid to power other loads When you are drawing power from the utility (i.e. when your RE system is not supplying enough power for your electric loads), your meter will run forwards. When your system is feeding power back into the grid, your meter will run backwards.

National programs such as Tekes (Kestävä Yhdyskunta), Sitra (Energiaohjelma), Motiva (Energiatehokas koti) should also contribute to energy efficiency in buildings.


Vertical Wind to Falkenberg

Energy company Eon together with Falkenberg Energy have purchased four wind turbines from Climate Solver Vertical Wind.  It’s clear that large companies have the potential to create market demand and support the further development of low carbon technologies. We hope to see more of this in the future!

On the Road to Success

Our colleagues at WWF Finland are committed to help their government onto the path to a low carbon future. A recent initiative is to share Smart Climate Solutions case studies with them with the objective of influencing their climate and energy strategies and actions. I thought I’d share them with you as well to provide leverage for your own lobbying work.

First up is the German Feed-in Tariff System for wind and other renewable energy

The German feed-in system, the German Law on Renewable Energy (Das Erneuerbare-Energien-Gesetz, 2000, hereafter EEG) laid down the framework conditions for rapid growth of renewable energy sources (RES) in Germany during the 21st century. The feed-in system, which guarantees the RES producers a fixed price per kWh fed into the grid, has been at the core of the German renewables success story – over tripling the amount of renewable energy since 2000. The leading renewable energy source in 2006 – wind power provided 30,7 TWh or some 5 % of total electricity production (see picture below, Mrd. kWh = TWh).


In practice the EEG legislation (amended in 2004 and regularly reviewed) obligates electric utility companies to purchase renewable energy at set rates over the next 20 years. These in turn are allowed to redistribute the additional cost to the general public in the form of higher electricity rates – hereby there is an equalization of additional costs from RES between all grid operators and electricity suppliers. The feed-in system, building on substantial R&D as well as market simulation programmes during the 1980s and 1990s introduced two innovative aspects to RES policy implementation, in particular i) a degression of tariffs, supporting technology learning, and ii) a stepped nature of tariffs, supporting financial efficiency.


While in Germany the tariff (in 2006 ranging from ca 5 to 57 €cent/kWh) is guaranteed for approved renewable energy projects for a 20-year period from the plant commissioning, from 2002 onwards new installation have received lower tariffs (degression rate ranging from 1-6,5%/year depending on RES technology) in order to retain the incentive for manufacturers to systematically reduce production costs and offer more efficient products each year. The stepped tariffs, by defining the tariffs for different technologies based on yield/generation costs of each plant (e.g. for wind power depending on site-specific wind yield) the price of the tariff mirrors the cost resource curve of the technology, which results in a reduction of the producer profit and therefore in lower transfer costs for society.


Key challenges in implementation and drivers/reasons of success


The international experiences of feed-in tariffs in several countries point to rapid increase of renewable technologies on energy markets unless hampered by major barriers (e.g. administrative, grid access). In Germany, a well suited additional support mix has been crucial for the overall success of the feed-in system. The complementary policy measures have included soft loans and investment incentives by the market incentive programme for biomass CHP, small hydropower, PV in schools, tax incentives (reduction of income tax granted in the federal tax law especially for wind energy investments) as well as soft loans by a federal investment bank. This framework has been administratively well coordinated on federal level by three key ministries, received strong political and financial backing on state level and catalyzed active cooperation in different technology sectors.


Assessment of CO2-emission reductions and if available any preliminary estimates of emission reduction costs (euro ton/CO2ekv)


The EEG has considerably contributed to annual GHG reductions in the order of tens of millions of tons. In 2006 the reduced GHG emissions, due to RES in electricity production was estimated to some 44 million CO2- tons. Looking at the economic costs of this energy sector transformation, the additional costs for consumers has been estimated to a mere € 0.007 per kilowatt-hour (kWh), corresponding to less than 4 % of the average consumer price for German rate payers.


Presentation of existing estimates concerning ancillary effects and benefits


With regards to economic ancillary effects the EEG has been the key contributor to the growth of the renewables sector into a over 20 billion euro business in Germany proper with in addition considerable export – in 2006 the export share of the German wind power industry raising to above 70%. Likewise the EEG has contributed to rapid employment growth in the renewables, approaching a total 250 000 employed. Even taking into account the negative transitional and structural effects in other economic sectors (incl. losses in purchasing power), the total positive employment effects reach some 70 000-80 000, with wind power leading the employment growth numbers. In addition, the EEG has contributed to improved energy security and cost-savings through avoided coal and gas imports.


Preliminary assessment of feasibility and any required modifications for similar policy measures in Finland


As the feed-in system can support a broad portfolio of RES technologies a system specifically tailored for the Finnish conditions could be rapidly introduced – taking into account the maturity and competitiveness of available technologies in Finland as well as the open energy markets. As in Germany the feed-in system could become a key policy measure in the Finnish national climate and energy strategy implementation.


The key criteria for success lie in the high price security and market stability, which creates the long term planning security for investors. The Finnish feed-in system could guarantee a dynamic market based premium and be differentiated in order to promote technology learning and market success in specific areas of global RES market growth, be it wind power in cold & arctic regions or distributed bioenergy based CHP solutions.


In this respect the German system with a stepped nature and degression of tariffs may provide some useful guidance for a Finnish system that should adapt to technological development and foster innovation. The international feed-in experiences from over 40 countries[6], covering close to 20 EU countries provide a solid basis for designing a Finnish system with lean administrative costs and coordinated network management with high stability and solid grid integration. The Finnish supporting policy mix will also need to be adjusted and diversified to allow rapid deployment of available renewable technologies.

Exciting things already happening in Copenhagen

Earlier this week a number of interesting people gathered to develop the idea of a low carbon city development index. Objective: to accelerate development towards a low carbon society.

Copenhagen Declaration for a Low Carbon City Development

For the first time in human history more than half of the world’s population now lives in cities. This has amongst other things created a strong demand for sustainable urban development across the globe. It has become evident that this need can not be met through traditional development as there is growing evidence of the adverse effects caused by the emission of greenhouse gases and intensive use of natural recourses to provide a high quality of life.

Therefore the cities of tomorrow must be fundamentally different than the cities of today in order to ensure sustainability. In this transition it is important to focus on service needed, not the ways they have been provided previously. For example, instead of only improving cars and roads the service of mobility and transportation should be in focus encourage smart solutions and IT-solutions that reduce the need of energy consuming trips and thereby also buildings.

This service perspective is especially important when we look at cities in regions like China and India where more than half of the world’s building will be build over the coming years and where more than 10 million people are moving into cities every year in China alone.

In order to ensure that economic development, a low carbon economy and a resource efficient development go hand in hand we should approach this transition as an opportunity.

A global approach to cities
As all cities are integrated parts of national, regional and global economies it is important not to view the transition to a low carbon city in isolation. Cities should be seen as living entities that through import and export interact with the rest of the world. No city can be seen as sustainable without considering the consequences of the import and export. With the need for low carbon solutions cities that provide these solutions are particularly important and sustainable import should be encouraged where possible.

A low carbon city development index
“What you can’t measure you can’t manage” is an old truth that also applies to cities. A low carbon index for cities would make it possible to measure the progress towards a low carbon society and support three important aspects of low carbon development
• Development of a low carbon city development policies, capturing the global impacts of the city
• Dialogue and exchange of best practice between cities around the world
• Comparison of various cities development paths and how far they are in the transformation from a carbon intensive city to a low carbon city

In order to achieve this, a commonly accepted global index that in a meaningful way can measure a city’s progress towards a low carbon future is needed. Several indices attempt to do this at the national level but no index exists at the global level, and none of the existing indices so far include import and export as relevant factors. The new “low carbon city development index” will address this gap through the development of a global index for low carbon cities and by identifying policy measures that efficiently foster and facilitate the above mentioned transition.

The index will be based on the concept of a carbon budget, accounting for equity a the ecological limits for the global CO2 emissions in order to avoid dangerous climate change, and will be divided into three different parts covering the effects from direct measures as well as measures related to export and import:

1. Indicators assessing the direct carbon emissions in the city
To which degree does the city directly contribute to increased or decreased carbon emissions and impact the environment?

2. Indicators assessing the carbon footprint from export
To which degree do products and services originating from the city result in increased or decreased carbon emissions and impact the environment impacts at place of consumption?

3. Indicators assessing the carbon footprint from import
To which degree do the city sources, materials and services contribute to increased or decreased carbon emissions and impact the environment at place of origin?

We, the undersigned, support the development of a low carbon city development index and will pay extra attention to the needs in emerging countries such as China and India. We will encourage all relevant stakeholders to support this effort.
