A successful German ENERGIEWENDE (energy transition) is inevitably linked to energy efficiency. The focus of climate protection efforts needs to be on energy savings and a highly efficient energy use on all levels – from production to consumption. The lower energy consumption also contributes to attaining Germany’s ambitious targets for the expansion of renewable energies.
The German market for energy services and energy efficiency is characterised by a vast number of different instruments, activities and players. The framework is set on the European as well as the domestic level. In order to create incentives for an increased energy efficiency and energy savings on the end-consumer side, the offer of information and consultation services is complemented by certain subsidies.
Germany’s biggest energy saving potential lies in its existing buildings. These buildings consume three times more energy compared to newly built buildings. Besides, space and water heating already accounts for around 85% of private households’ total energy consumption. Until 2020, the German government aims for a 20% reduction in the heat demand for buildings, and a 50% reduction until2050. Moreover, the primary energy consumption should be lowered by 80% until 2050 – in conjunction with a doubled rate of building refurbishments. It is expected that around 50% of private older buildings shall be renovated in the near future. To achieve the target of energy savings of 25%, estimated investments of EUR 540bn will be required. However, marketable innovative technology would already allow for savings of up to 85%.
In order to reach the set targets, the German Federal Ministry for Economic Affairs and Energy (BMWi) launched the National Plan on Energy Efficiency (NAPE) in 2014. The goal is to virtually have a climate-neutral building stock by 2050. Buildings account for nearly 40% of the total final energy consumption in Germany (BMWi). In 2015, more than half of the immediate measures, e.g. expanding on-site energy consulting or tax incentives for energy retrofits, have been reached. In 2016, the implementation of NAPE will be continued.
Germany is a global leader in the energy efficiency sector. The German government’s Integrated Energy and Climate Programme (IEKP) will promote the sector even further. The German energy efficiency industry generates an annual turnover of around EUR 135bn (2015), with the market growing by 10% in comparison to 2014. Over the next few years, the industry is expecting double-digit growth rates. There are more than 500,000 people employed in the German energy efficiency market already (DENEFF 2016). There is high potential in smart metering, insulation systems, insulated glazing, heating and cooling technologies, efficient home appliances, energy-saving lamps, cogeneration systems, pumps and compressed air systems.
New Zealand’s government aims to promote the country’s sustainability. Their aim is to generate 90% of the country’s electric power demand through renewable energy sources by 2025 and to reduce CO2 emissions by 50% by 2050. Simon Bridges, Minister of Energy and Resources, announced that energy savings achieved by large energy users through EECA (Energy Efficiency and Conservation Authority) programmes have resulted in an additional direct carbon reductions of 9,000 tonnes p.a. so far in 2015/16. Further, energy efficient measures are highly encouraged in order to reduce the steadily increasing energy demand of 1% on average p.a.
The construction sector, and the building sector in particular, observe energy efficiency more than other sectors. Thousands of building consents are granted on a monthly basis, mainly driven by the rebuild of the city of Christchurch and increased building activities in Auckland. New Zealand’s ‘Building Code’ stipulates specific requirements to achieve energy efficient buildings and thus creates a basis for standards and minimum requirements.
Christchurch will be rebuild as a model city for energy efficiency. The total costs for the rebuild are currently estimated at 40 billion NZD which does not include costs for repair and improvement. 50% of the costs are to be attributed for residential buildings, 20% for commercial buildings. The rebuild offers opportunities for implementing energy efficient products and building construction thus creating future proof and energy efficient buildings. Auckland is New Zealand’s biggest city and home to approx. 1.5 Mio people. However, the city expects further growth and sees an increase by 1 Mio. additional people by 2040. This exerts considerable pressure on the current residential home situation and asks for more residential buildings/apartments to accommodate more people. In order to fulfil future requirements, Auckland Council has introduced the “Auckland Plan” in March 2012; the plan outlines sustainability and energy efficiency which is leading motif of the plan.
Based on the current situation, the NZGBA in cooperation with the German Chamber of Commerce in Australia organises annual trade delegations to New Zealand and Australia focusing on Energy Efficiency in Buildings. Click here for more information about these projects.
