• CONTROLLING CO IN CAR-PARKS

    Carbon monoxide control is a major challenge in covered car parks. In absence of proper ventilation system, parking facility presents several Internal Air Quality problems. Most serious is the emission of high levels of Carbon-Monoxide (CO) as it is easily absorbed by Hemoglobin in Human Blood inhibiting Oxygen delivery to body causing adverse health effects varying from headache to death. Thus ventilation system should have adequate air movement inside the basement when operating under normal conditions; should be able to satisfactorily dilute/extract CO produced from vehicles. By using CFD analysis we ensure that the ventilation system meets the NBC, ASHRAE and WHO guidelines for CO exposure and contaminant control etc.…

  • Using BIM to Transform Healthcare Industry

    BIM in health infrastructure examines the application and implementation of BIM technology in the planning, design and construction of health infrastructure. The inclusion of BIM within an internationally accepted framework of this highly illustrated reference book applications case study organizations, the main challenges for the implementation of BIM in healthcare to navigate how to motivate and train staff to overcome resistance to change and the development of the business case. Besides being different, general contractors find healthcare buildings the fiercest ones because of technology upgrades, their unpredictability, the large area and inconvenience in maintaining obstructed activities on site. Most EPC companies would rather build something else as rehabilitation or even…

  • HVAC IMPORTANCE FOR HUMAN COMFORT & WORKING ENVIRONMENT

    The complete life cycle of a building depends on the design stage. In the case of HVAC systems, a good design saves input energy and provide better indoor environment. Office buildings are used for business activities, and occupants that competently complete their task if they are comfortable. Factors that affect comfort are: • Air Quality • Indoor Temperature • Air Speed • Lighting Quality HUMAN COMFORT TEMPERATURE Subjective factors come into play when dealing with human comfort. For this reason, the main challenge is to achieve comfortable temperature for as many people as possible. • Human productivity increases within a temperature range of 21°C to 25°C. • An antagonistic effect…

  • EFFECTIVE ISOLATION ROOM FOR COVID-19 PATIENTS USING CFD

    Year 2020 has started with a ill starred severe acute respiratory virus (SARS-CoV-2)” and disease named as COVID-19, creating massive pressure on healthcare infrastructure as well as on healthcare management globally with each passing day. It has been observed that COVID-19 spread between people through close contact. There is neither vaccine nor specific antiviral treatment for COVID-19. To reduce transmission through air there is an immediate need of “Isolation Rooms” in the area of highly populated densities. This blog will discuss “how we can examine contamination extent with a convenient ventilation strategic design using CFD analysis”. During designing HVAC systems for the isolation rooms, CFD evaluates air flow patterns and…

  • BIM ADOPTION AND IMPLEMENTATION IN THE WORLD OF AEC

    Building Information Modeling (BIM) is accelerating more intensively and has become a primary aspect throughout the AEC industry. This expeditious rate of adoption within the industry has been promoted through governmental mandates, client requisite and through its applications in large organizations. Till the 20th century Architectural and Technical drawings were drawn by trained draughtsmen where drafters would help convert the design conceptions and sketches of an architect to technical detailed plans. In 1963 Ivan Edward Sutherland developed the very first Computer-Aided-Design (CAD) the solution to help architects, designers, drafters, and engineers understand how a computer can help aid in the making, modification, duplication, analysis of designs. In the early 1980’s…
