Abstract In the last years, new technical standards for assessment of energy efficiency building systems were developed by European Committee Standardization (CEN). These procedures conceived as to combine easiness calculation methodologies and their related assumptions with a sufficient level accuracy. While former objective is often achieved, latter challenging task sometimes fail simulate in...
Para climas predominantemente quentes, a ventilação possui papel fundamental no conforto térmico ao retirar carga térmica dos ambientes e auxiliar nos processos de trocas térmicas do usuário. No entanto, os natural não são elementares, demandando modelagens complexas para sua estimativa verificação das exigências térmico. O objetivo deste trabalho é comparar diferentes estimativas coeficiente p...
In this study, we investigate the maximum possible profit for a commercial office building participating in New York’s Day-Ahead Demand Response (DADR) program. We formulate an optimal control problem, assuming perfect knowledge of future weather, occupancy, and day-ahead electricity price predictions to examine this potential benefit. Then, a practical control strategy based upon the framework...
To analyze the effect of summer ventilation on the thermal performance and energy efficiency of buildings utilizing phase change materials (PCMs), this paper simulated the indoor temperature variation and energy saving performance of buildings constructed with PCM under different ventilation conditions from June to September. With EnergyPlus and degree-day method, 48 ventilation schemes, includ...
Building envelope optimization always occupies an important place in sustainable building design. This paper selects a large-scale space as research object, which requires more complex and flexible fenestration system. On the premise of complying with some rules, the fenestration is easily managed by adjusting the number and position of small rectangular patches on the grid-based exposed surfac...
Standard (black-box) regression models may not necessarily suffice for accurate identification and prediction of thermal dynamics in buildings. This is particularly apparent when either the flow rate or the inlet temperature of the thermal medium varies significantly with time. To this end, this paper analytically derives, using physical insight, and investigates linear regression models with n...
The main objective of this work is to develop a method for sizing window area based on the consumption of electricity in commercial buildings, when integration of daylight and artificial light with hybrid ventilation is considered. The method allows the estimation of the potential for electricity savings and the evaluation of the daylighting performance. Models operating with artificial and nat...
The objective of this study is to determine the most energy efficient and cost effective combination of architectural elements and mechanical systems to specify in an office building while maintaining a comfortable and healthy indoor environment for the occupants. A commercial office building located in the Minneapolis area with three heating, ventilating, and air-conditioning (HVAC) systems an...
Reliable prediction of system status is a highly demanded functionality of smart energy systems, which can enable users or human operators to react quickly to potential future system changes. By adopting the multi-timescale nexting method, we develop an architecture of human-in-theloop energy control system, which is capable of casting shortterm predictive information about the specific smart e...
Abstract Although solar radiation exposure strongly impacts people's thermal comfort, workstations are frequently positioned close to glazed façades. Solar adjustment models have been developed include the impact on which Fanger and Adaptative do not address. Nonetheless, those present differences in their calculation procedures, thoroughly investigated. This study aims verify comfort results b...
