“We will make Germany the most energy-efficient economy in the world” – that’s the goal set out by Germany’s new federal government in its coalition agreement. To achieve this, the government wants to increase the share of renewable energies to 65% by 2030. An energy efficiency strategy aims to help reduce energy consumption by 50% between now and 2050. For Andreas Kuhlmann, Chief Executive of the German Energy Agency, those are ambitious goals: “2018 will be a pivotal year for climate conservation and the energy transition.” A series of commissions has been tasked with drawing up strategies and concrete measures in the course of this year.
As the building sector accounts for almost 40% of energy consumption in Germany, the need for action in this area is particularly great. But how can energy use in buildings be made as efficient as possible? This issue is the central focus of the exhibition EM-Power, which will be taking place for the first time in Munich from June 20–22, 2018. The exhibition is aimed at professional energy customers, i.e. at operators, energy officers and planners of commercial residential buildings and neighborhoods, municipal properties, hospitals, hotels and restaurants. Read about the challenges that the individual industries must overcome, and how they can be solved, on this page.
While 50% of the world’s population currently lives in cities, in Germany this figure reaches 75%. This means that residential buildings and neighborhoods in cities have a particularly significant role to play in the energy transition. While the focus previously tended to lie on increasing energy efficiency in individual buildings, it is now shifting to building complexes and neighborhoods – when systems here are shared, the energy is used more efficiently and cost effectiveness can be increased. In neighborhoods, great potential for energy savings is created not just by individual technologies but by smart and efficient interaction between them within the system. Read more
If energy efficiency in hospitals and care facilities were a patient, it would be in a bad way. “Healthcare facilities are the biggest energy consumer in the trade, commerce and services sector,” observed Franz Untersteller, Environment and Energy Minister for the state of Baden-Württemberg, three years ago. On average, he said, each individual hospital bed uses about the same amount of energy as two single-family homes per year. According to estimates, in many cases operators could save up to 40% on current electricity usage and 32% on heat. But what specific measures can be taken to increase energy efficiency in hospitals and care homes? And where can operators and building services engineers learn more about this issue? Read more
By 2050, the aim is for Europe’s building stock to be largely greenhouse gas neutral. But even wealthy Germany is lagging behind its own climate conservation goals when it comes to modernizing its buildings with green retrofits. However, public sector properties hold significant potential for improvements to energy efficiency and, as a result, lower costs. The approximately 186,000 buildings owned by the federal, state and local governments across the country generate energy costs of around 6 billion euros each year. The local governments alone pay around 3.4 billion euros for heat and electricity supply in the buildings they own. There are many different types of public buildings, from administrative offices to sewage plants to schools – and the possibilities for increasing energy efficiency are just as varied. Read more
Hoteliers and restaurateurs already spend up to 10% of their annual turnover on energy, and this figure is rising. Energy costs have for years been cited as the biggest problem facing the hotel and gastronomy sector in economic surveys by DEHOGA, the German Hotel and Restaurant Association. The higher a hotel’s rating, i.e. the number of stars it has, the higher its energy and water demand usually is. Wellness facilities such as swimming pools and saunas are particularly energy intensive. And the energy infrastructure was often pieced together over the years and is now outdated. At the same time, there is frequently no suitably qualified and experienced staff to manage the energy systems. There is a wide range of possibilities for optimizing energy use in hotels and restaurants. Read more
Growing numbers of hotels and restaurants are including e-bike and electric car charging in the services they offer their guests. Local authorities are adding electric vehicles to their fleets and investing in public charging stations to fulfill their role as pioneers. The power used often comes from photovoltaic systems owned by the business or authority themselves. If these systems at least occasionally generate more power than is needed, energy storage can be a worthwhile investment. This topic too will be under the spotlight in Munich, as three other exhibitions will be taking place alongside EM-Power. This gives attendees the chance to enjoy four events in one visit:
How can a hospital’s high energy costs be reduced? Is energy contracting worthwhile when renovating a school’s heating system? What current developments are relevant for professional energy customers? Energy officers, facility managers or project developers looking for answers to these questions will find them not just at the exhibition EM-Power itself but also, from March, in a biweekly newsletter with examples of best practice for a range of industries including hotels, hospitals, production facilities and commercial residential buildings. The newsletter will also use interviews and a selection of news items to report on current issues that will be of interest for building and facility managers, planners and consultants working in industry, real estate and local government.
