Model Predictive Control in buildings with thermal and visual comfort constraints

Model Predictive Control can cope with conflicting control objectives in building energy managements. In terms of user satisfaction, visual comfort has been proven in several studies to be a crucial factor, however thermal comfort is typically considered the only important aspect. Besides human well-being, visual comfort strongly impacts the...

Test rooms to study human comfort in buildings: A review of controlled experiments and facilities

Occupants’ comfort perception affects building energy consumptions. To improve the understanding of human comfort, which is crucial to reduce energy demand, laboratory experiments with humans in controlled environments (test rooms) are fundamental, but their potential also depends on the characteristic of each research facility. Nowadays, there...

The impact of using Closed Cavity Façades (CCF) on buildings' thermal and visual performance

Glazing is a critical buildings element as it is the most vulnerable envelope part to heat gain and heat loss accounting for around 50% of a building's energy consumption. However, conventional glazing technologies have relatively low-performance characteristics which cause significant heat losses during winter and undesired heat gain in...

Sun shading of the future: A next generation workflow for applying the performative computational architecture framework to sun shading design, based on an example sun shading system for high-rise office buildings with all-glass exteriors in tropical climates optimised on visual and thermal comfort

This thesis is about improving the workflow for applying the Performative Computational Architecture (PCA) framework to sun shading design. The PCA framework is a design approach consisting of three phases; form-finding, performance evaluation and optimisation. The conventional workflow in regard to sun shading design is defined as a combination...

Phase changing solar shading: On the integration of phase change materials to improve the solar shading efficiency

Energy consumption around the world increases by the day. The primary energy usage has risen with approximately 49% and the CO2 emissions with 43% during only the last two decades. The building sector in the Netherlands contributes for approximately 36% to this energy consumption and office buildings are one of the larger consumers (Rijksdienst...

Adaptive Façade Design for the Regulation of Visual Comfort

The building sector in Europe represents 40% of the energy consumption and, of this amount, 26% is represented by office buildings that demand 44% of the energy only for lighting. Therefore, architects and engineers have a big responsibility to find design strategies and technologies that answer to this issue. In particular, a possible approach...

Climate responsive facade system with translucent PCM

The European Union has approved the Energy Performance of Building Directive, requesting all new building to be near Zero Energy by 2020. This has created challenges and opportunities in the building sector, encouraging the creation of new solutions, which are both energy efficient and environmental friendly. Between many possible explored...
