Design Smart, Build Clean, Live Healthy!

I find deep motivation for what I do, no matter how small the contribution, in the idea well encapsulated by this quote from the Australian politician Moses Henry Cass  (18 February 1927 – 26 February 2022): " We have not inherited this earth from our parents to do with it what we will. We have borrowed it from our children and we must be careful to use it in their interests as well as our own . Anyone who fails to recognize the basic validity of the proposition put in different ways by increasing numbers of writers, from Malthus to The Club of Rome, is either ignorant, a fool, or evil" [1].              Cass in 1970  (Public Domain) Reference: [1] 1975, Australian Government Digest, Volume 2, Number 4, (1 October 1974 – 31 December 1974), (Text of speech on Environmental Policy given by Dr. Moses Henry Cass, Minister for the Environment and Conservation for Australia, Speech was delivered on November 13, 1974 at the Ministerial Mee...

Appel d'offres pour la construction du Centre d'Excellence de Formation Technique et Professionnelle à la Plateforme Industrielle d'Adétikopé au Togo

                 Le Ministère délégué chargé de l'Enseignement Technique du Togo lance un Avis d'Appel International à Manifestation d'Intérêt pour le marché de travaux de construction du Centre d'Excellence de Formation Technique et Professionnelle à la Plateforme Industrielle d'Adétikopé (CEFTP-PIA) . Ce projet s'inscrit dans le cadre du Programme de la Promotion Intégrée de la Formation Professionnelle et de l'Emploi (PIFPE), avec un financement de la Coopération Allemande à travers la KfW — Banque de Développement. Le Centre d'Excellence, d'une superficie d'environ 6 000 m² sur une parcelle de 10 500 m², sera construit selon des normes environnementales, économiques et sociales, avec une approche bioclimatique . Le programme spatial du CEFTP-PIA comprendra des ateliers agroalimentaires, textiles, de maintenance industrielle, logistique, ainsi que des espaces d'accueil, des salles de classe, une bibliothèque, une crèche, des espaces verts,...

ONAT, Ordre National des Architectes du Togo, enfin le numéro 202!

After 11 years of patient work and dedication, I have finally joined the small family of accredited Architects in my home country, Togo. On the last Thursday, January 11, 2024, the 3 rd episode of the yearly event, ONAT à la Rencontre du Togo (ORT-3) , was specially featured with the swearing-in of eleven Architects as new members of the National Order of Architects of Togo, ONAT. Among them, I am fortunate to take, on the national board of accredited Architects, the number 202 , which I subjectively appreciate for its beautiful symmetry. During the three-day event (January 10 - 12, 2024),  ONAT made a memorable encounter with the people of Sokoke, Chef-lieu city of the Central region. From open conferences and physical activities to meal-sharing and tourism, national government officials, local authorities, members of ONAT, as well as architects from brother countries (Ghana, Burkina-Faso, Côte d’Ivoire, Cameroun, Guinée-Bissau, Democratic Republic of Cong), and the local people...

Spatial and seasonal differences between near surface air temperature and land surface temperature for Urban Heat Island effect assessment

Abstract: In the context of global warming, urban thermal environments are a growing concern. Previous studies focused on Urban Heat Island effect and global warming mitigation amplitude with Land Surface Temperature (LST), ignoring the interaction of LST and Surface Air Temperature (SAT), which comprehensively affects pedestrian thermal comfort. This study examines the SAT-LST relationship to reduce the uncertainty about SAT prediction based on LST. Utilizing data from 280 air temperature sensors and Landsat satellite remote sensing, we quantified temporal and spatial variations between SAT and LST in Changsha (under a monsoon climate). Analyzing data from 2018 to 2022, the study found that: 1) There are spatiotemporal differences in the SAT-LST relationship, with strong spatial heterogeneity, notably in urban areas and during the summer; 2) A stronger correlation between SAT and LST in winter (R2 = 0.916, RMSE = 1.242 °C) than in summer (R2 = 0.500, RMSE = 1.517 °C); 3) UHI and S...

A Parametric-Simulation Method to Study the Interconnections between Urban-Street-Morphology Indicators and Their Effects on Pedestrian Thermal Comfort in Tropical Summer

Abstract: Numerous studies have explored the impact of urban morphology and geometry on outdoor thermal comfort, intending to provide practical guidelines for urban designers. However, research findings have been inconsistent, in part due to differences in the climatic settings and the investigated heat-stress indicators. This study proposes a parametric-simulation framework to observe the behavior of thermal comfort according to the possible combinations of building density (BD), street aspect ratio (AR), and orientation. Conducted specifically under a hot-and-humid tropical-savanna summer condition, the study found that building density and aspect ratio were negatively correlated to the Universal Thermal Climate Index (UTCI), with R2 coefficients of 0.99 and 0.91, respectively. The UTCI was improved by a 1.0 °C per 10% increase in BD and by a 1.02 °C per unit of AR increase. The performance of street orientation was significantly influenced by wind direction, and strong inter-influen...

Classes in Class, quite unexpected!

Social classes are a real thing, that's for sure. It's perceptible in many ways (from clothes to transportation, including the little gadgets different people use daily). And yet, I wasn't quite expecting this in a classroom; It just came hilarious to me, as if someone said: take this hard thing away, I want to sit on a real chair. Take a Look!
