Understanding sludge rheology and optimizing equipment performance is crucial for energy efficiency in wastewater treatment plants (WWTPs). This study examined sludge rheology after thermal hydrolysis pretreatment (THP) at 60, 80, and 120 ◦C for 2 h, followed by anaerobic digestion (AD) at 37 ◦C for …

Overzicht van manieren om door bewoners zelf geproduceerde energie (met name PV stroom) op te slaan, plus richtinggevende overwegingen. Gericht op belangstellende bewoners. 68 aanwezigen.

The objective of this study is to evaluate the energetic, exergetic, sustainability, economic and environmental performances of a 4-cylinder turbodiesel aviation engine (TdAE) used on unmanned aerial vehicles for the take-off operation mode to assess the system with large aspects. Energy efficiency of …

This study aims to check the performance of two distinct configurations system: a photovoltaic-thermal (PVT) system with an ice buffer storage tank figure [1] and a conventional PV system with an air heat exchanger on the back, figure [3]. The ice buffer storage tank is used to store excess heat from …

In Vlissingen, the municipality wants to make a selected neighbourhood natural gas-free. In order to support this, they have been granted a subsidy. There are many important stakeholders in this project such as the housing corporation l’Escaut which owns most of the houses in the neighbourhood. All of …

Older people are often over-represented in morbidity and mortality statistics associated with hot and cold weather, despite remaining mostly indoors. The study “Improving thermal environment of housing for older Australians” focused on assessing the relationships between the indoor environment, building …

The Heating Ventilation and Air Conditioning (HVAC) sector is responsible for a large part of the total worldwide energy consumption, a significant part of which is caused by incorrect operation of controls and maintenance. HVAC systems are becoming increasingly complex, especially due to multi-commodity …

District heating (DH) has a major potential to increase the efficiency, security, and sustainability of energy management at the community scale. However, there is a huge challenge for decision makers due to the lack of knowledge about thermal energy demand during a year.  https://www.mdpi.com/1996-1073/14/17/546 …

The Netherlands has a mission to use 16% of sustainable energy by 2023, and 100% of sustainable energy by 2050, thus making green energy to be the only source of energy in the future. Foundation Loswal “De Bonnen” has 17.5 hectares of raw land where they want to develop a digester. The aim of this paper …

Current methods for energy diagnosis in heating, ventilation and air conditioning (HVAC) systems are not consistent with process and instrumentation diagrams (P&IDs) as used by engineers to design and operate these systems, leading to very limited application of energy performance diagnosis in practice. …
