A new wind direction-driven heat convection model is needed in dynamic simulati...

Wind plays an essential role in the heat convection on building outside surfaces. In EnergyPlus, a dynamic simulation program, heat convection models present several limitations reported by the scientific community. However, this communication reveals and discusses some implications that highlight the importance of developing more accurate models. The current models are first analyzed to identify what are the p...

SARS-CoV-2 air and surface contamination in residential settings

SARS-CoV-2 transmission occurs mainly indoors, through virus-laden airborne particles. Although the presence and infectivity of SARS-CoV-2 in aerosol are now acknowledged, the underlying circumstances for its occurrence are still under investigation. The contamination of domiciliary environments during the isolation of SARS-CoV-2-infected patients in their respective rooms in individual houses and in a nursing ...

Thermal transmittance effect on energy consumption of Mediterranean buildings w...

High thermal mass construction is commonly used to reduce cooling energy consumption during the summer period as a passive design strategy in the Mediterranean region. Although being a generalized design practice, the benefit to the building performance is not fully consensual within the scientific community. This work explores the influence of thermal transmittance on the energy efficiency of buildings with di...

Performance-based design of multi-story buildings for a sustainable urban envir...

This paper critically reviews the role of performance-based generative design in fast prototyping of buildings, describes the methodology of an automated generative layout design to produce complete building solutions, and presents a case study of multi-story buildings in urban context. The proposed approach evolves the building design solutions by interacting with the city 3D geometry and evaluates the energy ...

Thermal transmittance of lightweight steel framed walls: Experimental versus nu...

Given the great influence of the thermal transmittance of the building envelope on the overall thermal performance and energy efficiency of the building, it is essential to accurately determine the U-value of the main building envelope elements. Due to the great heterogeneity of the thermal conductivity of the elements presented in a lightweight steel-framed (LSF) wall, and to the geometric complexity of some s...

Laboratory and in-situ non-destructive methods to evaluate the thermal transmit...

The experimental characterization of the overall thermal transmittance of homogeneous, moderately- and non-homogeneous walls, windows, and construction elements with innovative materials is very important to predict their thermal performance. It is also important to evaluate if the standard calculation methods to estimate the U-value of new and existing walls can be applied to more complex configurations, since...

Performance Analysis of a Solar DHW System with Adsorption Module Operating in ...

A numerical study was conducted on the performance of a solar domestic hot water storage system with an adsorption module operating in seven di erent world locations. The base system was optimized for Portuguese conditions and, without changing the system itself and the water consumption profile, its performance was investigated by altering local installation and operating conditions and solar collector inclina...

Deposição atmosférica de poeira e níveis de elementos traço numa cidade industr...

Este estudo foi realizado para examinar a influência de um complexo industrial, e o elevado volume de tráfego associado, na deposição de poeira atmosférica numa cidade com clima mediterrâneo. O dispositivo mais comumente utilizado para recolher a deposição atmosférica total consiste num sistema composto por um funil ligado a uma garrafa coletora. Dois sistemas foram colocados nas áreas exteriores de duas escola...

An integrated energy performance-driven generative design methodology to foster...

This paper presents a study on the application of lightweight steel framed (LSF) construction systems in hot climate. A generative design method created 6010 houses, with random geometry and random roof and exterior wall types with different insulation levels, and EnergyPlus was used to evaluate the energy consumption for air-conditioning of each building. The main goals were to determine which geometric variab...
