Consequentially, the energy demand for building cooling has become a serious concern. In particular, the energy peak demand that is intensified by the urban heat island (UHI) effect is often a critical issue for the outdated electricity infrastructure in many countries. In order to rationalize the building energy consumption while ensuring indoor thermal comfort, this paper explores the possibilities offered by the retrofitting of existing uninsulated roofs in combination with night natural cooling strategies. To this end, a case study was selected in order to investigate the performance of an extensive green roof (GR) with and without natural ventilation (NV). The selected building is located in Catania, southern Italy, in a very mild climate. Free-running conditions were evaluated together with air conditioning conditions during the daytime and free cooling via natural ventilation at night.

This study investigates the effects of such excess dosages on the properties of highly sustainable HVFA concrete. Four series of concrete mixes were designed, with Series 0 being the control concrete mix containing no fly ash and no superplasticizer. Series 50, 60 and 65 contained HVFA concrete mixes that had 50, 60 and 65% fly ash content, respectively. Series 50, 60 and 65 contained three similar mixes; in each series, the three mixes were prepared with the maximum dosage of superplasticizer at 2% of the binder by mass, and excess dosages at 3% and 4%, respectively. The effect of the excess doses on slump, flowability, compressive strength, flexural strength, tensile splitting strength, and abrasion resist...","PeriodicalId":38108,"journal":{"name":"International Journal of Sustainable Building Technology and Urban Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/2093761X.2016.1167643","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60075591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Artificial pavements are one of the key factors for the urban heat island effect. Due to high irradiance, the ambient air temperature rises above human thermal comfort levels. Studies have shown that ambient air temperatures above asphalt and concrete surfaces are significantly higher than those above ICBP pavements. Typically, paving blocks are used in public spaces that are generally used by pedestrians. During the daytime, the surface temperature of pavements rises and walking on pavements becomes very uncomfortable. The thermal behaviour of interlocking concrete block pavements is mainly governed by solar irradiation. When pavements are exposed to solar radiation, paving blocks are heated and the temperature of their top surfaces rises. Several factors such as heat capacity, convection film coefficient, and heat conductivity directly affect the temperature of ICBP. In this study, a fini...","PeriodicalId":38108,"journal":{"name":"International Journal of Sustainable Building Technology and Urban Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/2093761X.2016.1172278","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60075674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, International Commission on Illumination (CIE, from the French name of the organisation, Commission Internationale de l’Eclairage) sky models are considered for many such simulation tools. The characteristics of tropical sky are different from those of CIE skies, hence the usage and validity of these tools could be unreliable for research involving tropical regions. The aim of this study is to validate the Radiance program in the Integrated Environmental Solution – Virtual Environment (IES-VE) software by measuring daylight in furnished and unfurnished rooms under Malaysian tropical sky. Daylighting measurement and simulation were carried out over eight days in unfurnished and furnished rooms under both intermediate and overcast skies.

CEBs typically experience a 50% reduction in compressive strength when saturated. As a result, CEBs are typically stabilised with Portland cement, hydrated lime, or metakaolin. More recently, a commercial silane/siloxane water-repellent admixture with the tradename Plasticure, specifically designed for earth construction, has become available. This paper is an experimental investigation of the influence of Plasticure on the dry and wet strengths of CEBs stabilised with Portland cement, hydrated lime, and metakaolin. Prisms were tested wet and dry with three repetitions each. In total, 106 specimens were tested. The wet specimens were soaked in water for 24 h before compressive testing. Typical CEBs without Plasticure absorbed water equal to 7 to 9% of their original weight. This resulted in reductions of compressive strengths from the dry condition by 40 to 50%.
