Urban territorial expansion generated in the last decades has brought a series of consequences, such as the variation between urban and suburban weather conditions affecting indoor temperature and increasing electricity consumption derived from the use of cooling systems. Current approaches of simulation models in residential buildings use indoor environmental data for carrying out validations to propose hygrothermal comfort alternatives for the mitigation of the effects of the external environmental conditions on the interior spaces of dwellings. In this work, an hourly evaluation of both indoor and outdoor environmental parameters of two case studies in a tropical climate was carried out, by means of a whole-building simulation approach tool during a week representative of the warmest period of the year. The integration of the collected environmental data in the theoretical model allowed us to reduce the error range of the estimated indoor temperature with results in normalized mean bias error between 7.10% and −0.74% and in coefficient of variation of the root mean square error between 16.72% and 2.62%, in the different indoor zones of the case studies. At the same time, the energy assessment showed a difference of 33% in Case 1 and −217% in Case 2 for final electricity consumption.

The hydrogen is an attractive energy carrier and electrolysis of water is the most efficient to H2 production process. The OER in the anode is the limiting reaction being the case of study. In the present work materials based on IrO2 and WO3 were developed in different mechanical mixing 100, 70:30, 50:50, 30:70, respectively, by means of a mechanical mixture from two chemical reduction syntheses. The IrO2 was obtained by 6.25 mM of IrCl3 dissolved in isopropyl alcohol by adjusting the pH with 1M NaOH and a 0.5 mol NH4OH reductant was applied by adjusting a basic pH of 13. The obtained precursor was filtered and calcined at 400 ° C for 1hr. WO3 was obtained from 10mM WCl6 dissolved in isopropyl alcohol and polyethylene glycol, generating a precursor of W (OH)x followed by a calcination process at 500 ° C for 1hr. The material was characterized by electrochemical techniques of CV, LV and EIS. The IrO2-WO3 (50:50) material has lower activation energy of overpotential at room temperature, and a maximum current density close to 20 mA /cm2 at 1.8V vs Hg/Hg2SO4.

In this research, the effect of the addition of zirconium oxide-synthesized nanoparticles on the microstructural development and the physical–mechanical properties of cement mortars with limestone aggregates was studied. Zirconia nanoparticles were synthesized using the co-precipitation method. According to XRD analysis, a mixture of tetragonal (t) and monoclinic (m) zirconia phases was obtained, with average crystallite sizes around 15.18 and 17.79 nm, respectively. Based on the ASTM standards, a mixture design was obtained for a coating mortar with a final sand/cement ratio of 1:2.78 and a water/cement ratio of 0.58. Control mortars and mortars with ZrO2 additions were analyzed for two stages of curing of the mortar—7 and 28 days. According to SEM analysis, mortars with ZrO2 revealed a microstructure with a high compaction degree and an increase in compressive strength of 9% on the control mortars. Due to the aggregates’ characteristics, adherence with the cement paste in the interface zone was increased. It is suggested that the reinforcing effect of ZrO2 on the mortars was caused by the effect of nucleation sites in the main phase C–S–H and the inhibition of the growth of large CH crystals, and the filler effect generated by the nanometric size of the particles. This produced a greater compaction volume, suggesting that faults are probably originated in the aggregates.
