Summer heat protection for buildings

Buildings protect users from cold, damp and heat. Summer heat protection is an issue that is becoming increasingly important in Germany due to climate change and the resulting longer periods of heat.  If summer heat protection is inadequate, unpleasant heat can quickly develop inside the building during the warmer months of the year, which can affect the well-being and health of the occupants and users. Indoor temperatures above 25-27° C must therefore be avoided.

Aquathermy from waste water: Using sewage treatment plants for dual energy production

To clean our wastewater from households and industry, sewage treatment plants consume a lot of energy: across Europe, they account for around 1 % of total energy production. This makes them among the largest municipal electricity consumers. For municipalities, this high electricity demand means a great financial burden. However, sewage treatment plants can be transformed from power guzzlers into electricity and heat producers, because both wastewater and sewage sludge have great energy potential.

The new partnership portal NETZ-WERK REGENERATIV

The energy transition can only succeed in collaboration

The tasks associated with the energy and heat transition are highly complex. We can only create intelligent and effective solutions by working together. Therefore, our newly founded NETZ-WERK REGENERATIV unites planners, manufacturers and implementers. Together we realise renewable energy supply solutions for existing and new buildings, neighbourhoods and municipalities. For energy- and cost-efficient solutions in building and neighbourhood supply.

Proper use of waste heat - synergies for neighbourhoods

About two thirds of the final energy consumption of German industry is required for process heat. Estimates put the savings potential in the process temperature range from 60 °C at around 125,000,000,000 KWh. In order to push ahead with the energy turnaround, it therefore also makes sense to use wastewater and waste heat.

Heat pump systems + geothermal energy: The ideal combination for the energy and heat transition

Modern heat pumps can use air, soil or water as energy sources. These sources have different temperatures. For the efficiency of a HP system, the source temperature makes a big difference. In this blog you will learn more about the impact that the choice of source makes.

Exergy and anergy: Why we need to change our understanding of energy

The word "energy" is currently on everyone's lips: energy crisis, energy production, energy consumption and energy saving are the buzzwords of the day. From a physical point of view, however, the term energy is often not used properly: Energy cannot be consumed, produced or saved, as the first law of thermodynamics states: energy is always conserved. However, it consists of usable parts, the exergy, and not directly usable parts, the so-called anergy.

CO2 consumption in industry: Renewable energies for buildings and processes

At goodmen energy, we specialise in decarbonisation in the building sector. 

But decarbonisation is also urgently needed in the industrial sector, as it is responsible for more than a fifth of greenhouse gas emissions - and  around 30 percent of final energy consumption in Germany.

Therefore industry plays an absolutely key role in the energy transition.

Hydrogen in the natural gas grid

In recent years, the element of hydrogen has become an integral part of the discussion about the German energy transition. The precious green hydrogen can be obtained from renewable electricity produced with the help of wind turbines and photovoltaic systems through electrolysis. In this process, water is split into its elementary components hydrogen (H2) and oxygen (O) by means of electric current.

Embodied energy and Cradle to Cradle (C2C)

The building sector is responsible for a large part of our resource consumption and greenhouse gas emissions: Around 40 % of our total energy and material consumption is caused by the building sector. In addition, it generates 36 % of greenhouse gases and about 33 % of all waste. The impact on the environment is therefore increasingly taken into account when new buildings are planned.

Renewable Energy and Sustainable Communities

In the future, architecture must be more closely aligned with climatic requirements. We need to think about energy solutions for the urban future, where houses and neighborhoods are designed to keep their energy needs low and, as far as possible, meet them themselves. How do we achieve this?
