Building performance simulationBuilding performance simulation (BPS) is the replication of aspects of building performance using a computer-based, mathematical model created on the basis of fundamental physical principles and sound engineering practice. The objective of building performance simulation is the quantification of aspects of building performance which are relevant to the design, construction, operation and control of buildings. Building performance simulation has various sub-domains; most prominent are thermal simulation, lighting simulation, acoustical simulation and air flow simulation.
Field-programmable gate arrayA field-programmable gate array (FPGA) is an integrated circuit designed to be configured after manufacturing. The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC). Circuit diagrams were previously used to specify the configuration, but this is increasingly rare due to the advent of electronic design automation tools. FPGAs contain an array of programmable logic blocks, and a hierarchy of reconfigurable interconnects allowing blocks to be wired together.
Zero heating buildingZero-heating building or nearly zero-heating building (nZHB) is a building having essentially zero heating demand, defined as having heating demand, Q’NH, less than 3 kWh/(m2a). The zero-heating building is intended for use in heating-dominated areas. The purpose of the zero-heating building is to supersede net-zero energy buildings as a way to bring building-related greenhouse gas emissions to zero in the EU. Zero-heating buildings address flawed net-zero energy buildings: the requirement for seasonal energy storage, in some cases poor comfort of living and narrow design options.
Vision processing unitA vision processing unit (VPU) is (as of 2023) an emerging class of microprocessor; it is a specific type of AI accelerator, designed to accelerate machine vision tasks. Vision processing units are distinct from video processing units (which are specialised for video encoding and decoding) in their suitability for running machine vision algorithms such as CNN (convolutional neural networks), SIFT (scale-invariant feature transform) and similar.
Processeur graphiqueUn processeur graphique, ou GPU (de l'anglais Graphics Processing Unit), également appelé coprocesseur graphique sur certains systèmes, est une unité de calcul assurant les fonctions de calcul d'image. Il peut être présent sous forme de circuit intégré (ou puce) indépendant, soit sur une carte graphique ou sur la carte mère, ou encore intégré au même circuit intégré que le microprocesseur général (on parle d'un SoC lorsqu'il comporte toutes les puces spécialisées).
Appareil électronique de faible puissanceUn appareil électronique de faible puissance est un appareil électronique qui a été conçu pour utiliser peu de puissance électrique, par exemple un ultraportable. Montre Les premières tentatives de réduction de la quantité d'énergie requise par un dispositif électronique ont été liées au développement de la montre-bracelet. Les montres électroniques ont besoin d'électricité comme source d'énergie, et certains mouvements mécaniques et mouvements électromécaniques hybrides ont également besoin d'électricité.
Behavioural change theoriesBehavioural change theories are attempts to explain why human behaviours change. These theories cite environmental, personal, and behavioural characteristics as the major factors in behavioural determination. In recent years, there has been increased interest in the application of these theories in the areas of health, education, criminology, energy and international development with the hope that understanding behavioural change will improve the services offered in these areas.
Building performanceBuilding performance is an attribute of a building that expresses how well that building carries out its functions. It may also relate to the performance of the building construction process. Categories of building performance are quality (how well the building fulfills its functions), resource savings (how much of a particular resource is needed to fulfill its functions) and workload capacity (how much the building can do). The performance of a building depends on the response of the building to an external load or shock.
Espresso heuristic logic minimizerThe ESPRESSO logic minimizer is a computer program using heuristic and specific algorithms for efficiently reducing the complexity of digital logic gate circuits. ESPRESSO-I was originally developed at IBM by Robert K. Brayton et al. in 1982. and improved as ESPRESSO-II in 1984. Richard L. Rudell later published the variant ESPRESSO-MV in 1986 and ESPRESSO-EXACT in 1987. Espresso has inspired many derivatives. Electronic devices are composed of numerous blocks of digital circuits, the combination of which performs the required task.
Efficacité énergétique (thermodynamique)En physique et ingénierie mécanique, l'efficacité énergétique (ou efficacité thermodynamique) est un nombre sans dimension, qui est le rapport entre ce qui peut être récupéré utilement de la machine sur ce qui a été dépensé pour la faire fonctionner. Aux États-Unis, pour les appareils et équipements résidentiels, elle est déterminée par le facteur énergétique (energy factor). Cette notion est souvent confondue avec une définition du rendement thermodynamique, pour des systèmes dont l'efficacité énergétique théorique maximale est inférieure à un, comme les moteurs dithermes ou les moteurs électriques.
