Abstract The interest in the energy efficiency of buildings and integration new technologies to reduce heating cooling loads through building envelope is not new. European Union (EU) committed decarbonising its stock as almost 50% Union’s final consumption for cooling, which 80% used buildings. article analysis performance a PV/T system (with heat mat) demand low-energy two-zone, single-family ...

Abstract Heat pumps are increasingly popular in individual buildings and could help to meet expectations of ambitious energy-environmental European goals until 2050. This paper presents the results energy simulations conducted TRNSYS for a single-family building depending on its location selected cities. For each city, air source heat pump (ASHP) was considered as an heating cooling building, t...

Although the Stirling engine was invented in 1816, this heat engine still continues to be investigated due to the variety of energy sources that can be used to power it (e.g., solar energy, fossil fuels, biomass, and geothermal energy). To study the performance of these machines, it is necessary to develop and simulate models under different operating conditions. In this paper, we present a one...

This paper describes the modelling and analysis of a 5 MW chilled water plant used for the cooling of a recently constructed data centre in the UK. The model was developed using the TRNSYS software with the aim of studying the impact of perturbations such as chiller failure on the water and air temperatures in the system. The model includes the chillers, hydraulic network (piping, valves and pu...

In the perspective of the Net Zero Energy Buildings as specified in the EPBD 2010/31/EU, we propose the concept and design of a modular unglazed solar thermal (UST) façade component for facilitating the installation of active solar façades. The renovation of existing buildings offers an opportunity to improve the energy efficiency when using such a system and a novel design methodology tackled ...

Light envelopes are more and more frequently used in modern buildings but they do not present sufficient thermal inertia. A solution to increase this inertia is to incorporate a phase change material (PCM) in this envelope. This paper presents the performance of a test-cell with a new structure of light wallboards containing PCMs submitted to climatic variation and a comparison is made with a t...
