Thermal Energy Storage (TES) methods have gained significant importance in reducing the energy demand of buildings. Among various TES methods, use Phase Change Materials (PCM) has emerged as a promising approach to store latent form and enhance thermal capacity buildings, thereby improving comfort. This study aims evaluate sensible accumulation cement mortars by incorporating microencapsulated phase change materials (10-20% weight) substitute for fine aggregates. The experimental...

This paper studies electrochemical realkalisation (ER) as a method of preventing steel reinforcement corrosion induced by carbonation. Prismatic specimens reinforced concrete were made with two types cement, Portland Compound Cement (CPC) and Pozzolanic (CPP). The exposed to an atmosphere 10% CO2 at 30°C 65% RH until partially carbonated was obtained. Then ER administered for 20 days using 1 A/m2 1M Na2CO3 or K2CO3 solutions anolytes. During the ER, pH anolyte measured regularly. In...

Para determinar el comportamiento energético de los edificios programas simulación dinámica son utilizados como métodos cálculo. Sin embargo, numerosos estudios han mostrado que existen diferencias notables entre esperado y real edificios. Uno factores identificados fuente incertidumbre en la es ocupación usuarios. Estos parámetros definidos habitualmente con estándares no reflejan realidad ocupantes. En este artículo, se presenta una investigación sobre influencia del presencia usuarios...

Sustainability is no longer a new concept. However, applying, measuring and reporting on the sustainability initiative still somewhat confused subjective issue. There huge variety of guidelines green building schemes differing natures, meanings wordings. Despite this, there one guideline providing crossreference between corporate social responsibility performance to help commercial property market completely incorporate into their activities. Therefore, this paper intends link...

Resumen El almacenamiento de energia, utilizan-do calor latente con materiales cam-bio fase (PCM), en la construccion, puede producir mejoras el acondi-cionamiento termico los edificios y reducir consumo energia. Por su posibilidad uso las parafinas microen-capsuladas aparecen como una buena alternativa tecnologica. En presente trabajo se expone aplicacion a mor-teros cemento cantidades 10, 15 20 %, dos tipos Portland relaciones agua/cemento 0,5, 0,7 1,0. Tambien verifica efecto fibras...

In the search for methods to incorporate Phase Change Materials (PCM) into Portland cement mortar mixtures, PCM based on paraffins adhered a silica-based matrix appear as suitable option. However, paraffin particles have been observed escape from silica when water is added. There are only limited data how use of such affects behaviour mortars. To evaluate effect this addition, mixtures were elaborated with 5%, 10% and 15% content, using CEM 42.5 I R 52.5 types. Physical properties density,...

Context: The use of solar energy, rather than an alternative, is the viable solution to energy demands our planet for sustainable development. Given population increase and quality life on a global scale, it very reasonable forecast in demand. In this context, refrigeration or heating systems are timely strategy follow.

The aim of this research is to evaluate the energy savings and environmental benefits contributed by vegetal facades in comparison with traditional ones. To end, a particular type facade (translucent green wall) has been designed, built, monitored an experimental building. All constructive components system are recyclable reusable. A similar without layer also installed same building compare both models. These two duplicate probes that record temperature, humidity, illuminance data. weather...

The use of thermal mass in buildings is an effective way to improve the building's interior comfort places with high diurnal temperature variation.Combined other passive strategies, can play important role energy efficiency building, minimizing necessity traditional conditioning systems.However contemporary construction tends industrializing light weight systems low mass.An innovative add mass` benefits latent heat storage capacity Phase Change Materials (PCM).In Solar Decathlon, solar...

In the last decades, urban climate researchers have highlighted need for a reliable provision of meteorological data in local context. Several efforts been made this direction using Artificial Neural Networks (ANN), demonstrating that they are an accurate alternative to numerical approaches when modelling large time series. However, existing varied, and it is unclear how much needed train them. This study explores whether training can be reduced without overly compromising model accuracy, if...
