What do Circular Strategies Mean for Current HVAC Systems in Utility Buildings?: An Exploratory Research

This research extensively examines the pivotal shift toward circularity within the European construction and building sector, with a specific emphasis on HVAC systems in utility buildings. It commences by underscoring the pressing urgency precipitated by the Paris Agreement of 2015 and subsequent climate objectives, necessitating reductions in...

Stand-alone Serviced Façade Panel

This thesis focuses on the design and implementation of a flexible, adaptable, and modular integrated unitised façade panel. The panel integrates air-to-air building services technologies for ventilation and/or heating and cooling, driven by electricity, to enhance user comfort under different climate conditions. The primary objective is to...

Simulation-based seasonal underground sensible heat storage integrated in a district heating network

This study assesses the role of (seasonal) thermal energy storage in the next generation renewables based central heating systems for the built environment in the Netherlands. Specifically, the neighbourhood "Karwijhof" in the city Nagele which is transitioning to a collective renewable district heating network incorporating 24 users. The study...

Optimized district heating system for combined operation with seasonal heat storage

This study optimizes the district heating network side of a high temperature community heating system powered by decentralized solar collectors and seasonal thermal energy storage (STES). Six network configurations are considered which have the potential to improve system performance compared to a base scenario. The base scenario consists of a 2...

A larger statistical basis and a wider application area of a re-derived PPD equation in the (NEN-)EN-ISO 7730 model

This paper has the objective to initiate a discussion on potential improvements or extension of the validity of the original equation of the Predicted Percentage of Dissatisfied (PPD), according to (NEN-)EN-ISO 7730. This paper is to be regarded as a supplement to a paper on a re-derivation of the PMV equation in the Fanger model (Roelofsen,...

Naturally Tokyo: found in translation?: A case study of Dutch Earth, Wind, and Fire system integration & optimization in an office building in Tokyo

Earth, Wind, and Fire (EWF) is a natural ventilation system developed by Dr Ben Bronsema for office buildings in the Western European climate. Powered by nature: ground temperature & gravity for cooling, wind for energy generation & ventilation, and sun for the heat and natural draft, this system claims not only to use little energy but...

A larger statistical basis and a wider application area of the PMV equation in the Fanger model: Application area of the PMV equation

For sedentary activities, the PMV equation, derived by Fanger, is mainly based on the research of Nevins et al. (720 test subjects). Nevins' experiments were later on repeated by Fanger, but with 128 college-age Danish subjects and 128 elderly Danish subjects, instead of American subjects. Rohles did the research from Nevins et al. again, but...

Predictive Temperature and Humidity Control in Integrated Building Energy Management Systems

Worldwide roughly 80% of heating and cooling systems in the building sector are currently dominated by fossil-fuel technologies. These systems, known as Heating, Ventilation and Air Conditioning (HVAC) systems have contributed to global climate change and global warming. These effects are the consequence of the increasing demand of HVAC systems...

A comparison of the dynamic thermal sensation between the modified Stolwijk model and the Fiala thermal physiology and comfort (FPC) model

Stolwijk developed a thermophysiological human model which, to day, is still the basis and inspiration for many other thermophysiological human models. The Stolwijk model used in this study is improved with regard of the calculation of the skin temperature and equipped with clothing as well as thermal sensation. Fiala also developed a...

Designing from Heritage: Strategies for Conservation and Conversion

This book – the third in the Rondeltappe series – reflects the philosophy and didactic approach of Heritage and Architecture (H&A) section of the Faculty of Architecture and the Built Environment (Delft University of Technology). H&A has three chairs: Design, Cultural Value and Technology. They work in close cooperation to lay the...

Combining knowledge and historical data for system-level fault diagnosis of HVAC systems

Interdependencies among system components and the existence of multiple operating modes present a challenge for fault diagnosis of Heating, Ventilation, and Air Conditioning (HVAC) systems. Reliable and timely diagnosis can only be ensured when it is performed in all operating modes, and at the system level, rather than at the level of the...

Bayesian Belief Networks (BBN) and Expert Systems for supporting model based sensor fault detection analysis of smart building systems

The Hague University in Delft uses an advanced climate control system. All sensors and actuators are monitored and deviations from the sensor data are reported daily. The building manager will have to combine the information from the sensor data in order to draw the right conclusions. In this paper, two possible solutions are described for...

An integrated control-oriented modelling for HVAC performance benchmarking

Energy efficiency in building heating, ventilating and air conditioning (HVAC) equipment requires the development of accurate models for testing HVAC control strategies and corresponding energy consumption. In order to make the HVAC control synthesis computationally affordable, such control-oriented models are typically a simplified version...
