Joseph, Sam (author)
In 1987, Brundtland coined the term "sustainable development" to tackle the worldwide issue of environmental deterioration. Subsequent to that, swift progressions in science and technology have resulted in climate change, characterized by a rapid increase in global temperatures. The primary objective of the Paris Climate agreement is to limit...

The International Energy Agency (IEA) emphasizes that using real building energy use data (RBEUD) to reflect the actual condition of buildings and inform policy-making is the most effective way to reduce buildings’ carbon emissions. However, based on IEA’s evaluation, regional and national building stock data are limited and lacking. Especially...

Many researchers have indicated the energy performance gap (difference between actual and predicted energy used in buildings), not only on an individual building level, but also on a building stock level. For policy makers it is important that predictions are correct on an building stock level to make them a useful tool to predict the effect of...

Monitoring the energy performance of very low and zero energy buildings is fundamental to evaluate the efforts made to transition into an energy neutral built environment. Post occupancy monitoring has been embedded into current practice, supported by the availability of smart meters and affordable sensor technology. However, there is still a...

Buildings are the main sector in energy consumption and CO2 emissions. Retrofitting of existing building has been identified as one of the significant strategies for reducing the impacts of buildings on energy and environment. However, recent studies have shown that low energy buildings mostly do not perform as expected. These differences are...

Buildings’ expected (projected, simulated) energy use frequently does not match actual observations. This is commonly referred to as the energy performance gap. As such, many factors can contribute to the disagreement between expectations and observations. These include, for instance, uncertainty about buildings’ geometry, construction, systems,...

A bottom-up building energy modelling at the urban scale based on Geographic Information System and semantic 3D city models can provide quantitative insights to tackle critical urban energy challenges. Nevertheless, incomplete information is a common obstacle to produce reliable modelling results. The residential building heating demand...

In order to ensure the sustainable development of cities, the existing building stock has to be transformed to stay relevant to the changing needs of urban dwellers and to reduce the economic and environmental impacts of cities on the planet. Thus, innovating and developing a strategy that prepares the built environment for 2050 is of...

Currently, clear European and Global climate goals, such as the Paris Agreement and the European Energy Efficiency Directive, are in place to stimulate more efficient use of resources and lower emissions. The built environment can play a significant role in reaching these objectives in the future since it consumes around 40% of the total energy...

Buildings don’t use energy: People do. Do highly efficient homes really save energy? Counter-intuitively, dwellings that use less energy have low energy efficiency, and those with higher energy consumption have higher efficiency. Moreover, even accurate building energy simulation for multiple buildings could not predict the actual energy...

The difference between actual and calculated energy is called the ‘energy-performance gap’. Possible explanations for this gap are construction mistakes, improper adjusting of equipment, excessive simplification in simulation models and occupant behaviour. Many researchers and governmental institutions think the occupant is the main cause of...

Majcen, D. (author)
Residential buildings are one of the key target sectors for energy and CO2 reduction. Research on the relationship between policy instruments and their effects is crucial for the continuous improvement of these tools. This thesis focuses on The Energy Performance of Buildings Directive (EPBD) as an EU flagship policy for technical improvements...

The energy saving policies of governments are not resulting in the energy saving they were aiming for[1]. Theoretical energy saving predictions are an important and frequently used tool for policy makers to develop energy saving policies and to set energy saving targets. Majcen et al. [2] showed a discrepancy between actual and theoretical...
