“…Additional, the opening of the windows and the set point of the HVAC system are other central issues. Nevertheless, in a previous publication of the first author it has been shown that blind operation has a strong impact on energy consumption of a building [2,15]. It is essential for the blind control to define solar gains allowance during daytime in order to save heating energy in the evening and during night time.…”

“…The aforementioned goals were achieved by preliminary studies that identify the important input variables for a control [30], assess the maximal saving potential of a blind control [2], and compare the energetic footprint of an optimal control to user behavior and simple on/off schemes [15]. The final control is based on a non-linear model predictive control (NMPC).…”

“…Furthermore, automated blinds and shading elements have been introduced to adapt to changing exterior conditions without the need for a highly conscious occupant who constantly adapts the blind position. 5 Finally, a great number of advanced or complex fenestration systems (CFS) were proposed in the past decade: electrochromic windows, gasochromic windows, laser cut panels, microscopic blinds, prismatic structures... However, these solutions all have their drawbacks, costs and do not apply in all situations.…”

Embedded microstructures for daylighting and seasonal thermal control

A novel concept for an advanced fenestration system was studied and samples were produced to demonstrate the feasibility. The resulting novel glazing will combine the functions of daylighting, glare protection, and seasonal thermal control. Coated microstructures provide redirection of the incident solar radiation, thus simultaneously reducing glare and projecting daylight deep into the room in the same manner as an anidolic mirror-based system. The solar gains are reduced for chosen angles corresponding to aestival elevations of the sun, thereby minimising heating loads in winter and cooling loads in summer.A ray-tracing program developed especially for the study of laminar structures was used for the optimisation of structures with the above mentioned goals. The chosen solution is based on reflective surfaces embedded in a polymer film that can be combined with a standard doubled glazed window. The fabrication of such structures required several steps. The fabrication of a metallic mould with a relative high aspect ratio and mirror polished surfaces is followed by the production of an intermediate Polydimethylsiloxane moulds that was subsequently used to replicate the structure with a UV curable polymer. Selected facets of these samples were then coated with a thin film of highly reflective material in a physical vapour deposition process. Finally, the structures were filled with the same polymer to integrated the mirrors.The samples were characterised using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), confocal microscopy and laser profilometry. A miniature goniophotometer was built to assess the performance of the structured glazing. The daylighting behaviour was successfully demonstrated.

“…In 2010, researchers continued developing and deepening previous studies, such as the energy use in the residential sector and its relationship to the behaviour of occupants [53][54][55]; window-opening habits relating with IAQ control parameters [56]; behavioural patterns respecting energy use by means of a survey [57,58]; and, activating shading devices and its relationship with lighting, heat gains, thermal comfort, and consequently, with energy use [59,60].…”

Energy-Related Occupant Behaviour and Its Implications in Energy Use: A Chronological Review

2018

Abstract:It is essential to understand how significantly occupants' actions impact the performance of a building, as a whole, in terms of energy use. Consequently, this paper reviews the available resources on energy-related occupant behaviour and its implications in energy use in a building. A chronological review on energy-related occupant behaviour and its implications in energy use has been conducted. As a main existing gap, it was identified by researchers the difference between real energy performance and the one that is predicted during the design stage of a building. The energy predicted during the design stage of a building may be over twice the energy used in the operation stage. Buildings are one of the most energy intensive features in a country. They are affected by the interaction and correlation of several different variables, such as: its physical characteristics, technical systems, equipment, occupants, etc. Therefore, buildings are considered to be complex systems that require a careful and intensive analysis. Moreover, one of the key variables impacting real building energy use is occupant behaviour. The way occupants behave and their motivations are some of the main aspects that need to be considered in a building life-cycle.
