Diminishing benefits of thermal mass in Iranian climate: Present and future sce...

Thermal mass, a pivotal element in a building’s performance, functions as an indoor thermal buffer. While literature underscores its advantages, the enduring impact of thermal mass amid climate change remains uncertain. This study methodically assesses thermal mass effects in 21 Iranian cities across contemporary and future climates, juxtaposing heavyweight and lightweight constructions. The EPSAP algorithm, a ...

Analysis of Climate Change Impact on the Energy Performance of Small Dwellings ...

The energy performance of buildings is heavily affected by weather conditions. This study evaluates the impact of climate change on the heating and cooling energy demand in dwellings located in Porto, Portugal. A synthetic dataset of 50 generated two-storey residential buildings is evaluated using dynamic simulation to assess the energy consumption for air-conditioning in three future climate change weather yea...

Developments of a bim Add-on Tool for Deep Renovation of Buildings

This paper presents the current state of development of a generation and performance evaluation tool to assist building practitioners in the early stages of deep renovation of buildings. This includes the tool workflow and its modules, such as the generative design method, the building performance evaluation mechanism, and the optimization procedure that improves the building geometry and construction system, a...

Daylight Modelling of a Portuguese Baroque Library

The XVIII century baroque King John’s Library is one of the most important buildings of the University of Coimbra, which was declared World Heritage patrimony by UNESCO in 2013. As one of the main touristic attractions, it has been object of study on the assessment of the books and furniture conservation. One of the aspects that affect their preservation is the exposure to daylight, which degrades the shelves f...

A Survey on the Impact of Energy and Buildings Sustainability Initiatives in Un...

University campuses are complex structures, generally consisting in large amounts of built-up area and of users involved in a diversity of activities, resulting in a substantial consumption of resources, waste generation and greenhouse gases emissions, similarly to an urban community. Acting on the use phase, the so-called operations, offers the possibility of improving the environmental performance of building...

Evaluating the Energy Performance of 20 Portuguese Wastewater Treatment Plants

Wastewater treatment plants (WWTPs) perform a prominent role in minimizing adverse environmental and human health impacts by subjecting wastewater to proper treatment, which ensures the quality of the treated water before discharging or reusing. Due to the complexity and diversity of processes involved, WWTPs are regarded as energy-intensive facilities, with energy costs accounting the second largest share of t...

Energy Audits and Energy Efficiency in Small Wastewater Treatment Plants: A Cas...

Energy plays an important role in the water sector. In fact, energy consumption by this sector accounts for nearly 44% of municipalities’ energy costs in developed countries. To minimize adverse environmental and human health impacts wastewater can undergo three treatment levels before discharge or reuse. Since it is an energy intensive process, wastewater treatment represents the largest share of water-related...

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...

An Aiding Tool for Building Design Generation, Thermal Assessment and Optimizat...

A building design aiding tool for space allocation and thermal performance optimization is being developed to help practitioners during the building space planning phase, predicting how it will behave regarding energy consumption and thermal comfort. The tool evaluates, ranks, and optimizes generated floor plans according to thermal performance criteria, using the dynamic simulation program EnergyPlus. The tool...
