Feedback from the AIVC/ASC 2024 Workshop in Singapore, “Ventilation, IEQ & Sustainability”

The AIVC 2024 workshop “Ventilation, IEQ & Sustainability" organised in collaboration with ASHRAE Singapore Chapter was held on 18-19 April 2024 in Singapore. Participation was possible in person and the event drew over 160 participants - researchers, engineers & architects and industry representatives. The programme included 21 presentations grouped into 3 sessions: “Optimising Indoor Air Quality for Climate Resilience”, “Reducing Carbon Footprints: The Role of Energy efficient Ventilation Technologies” & “Smart Building Automation for Climate-Adaptive Ventilation”.

Experimental Investigation of Indoor Air Quality in an Open Office Environment

Open offices, where more than one person works, have been used frequently in recent years. However, there are many studies on the efficiency of the indoor air quality of the employees in these offices. It has also been shown that the risk of cross-contamination is higher in such offices during the COVID period, but this risk can be reduced by increasing the amount of fresh air.

An argument for a reality check in the ventilation industry: We still have an energy crisis, in practice, and are not generally, in practice, achieving better indoor climate

In 2017 the Danish Building and Property Agency started a project titled “Avoiding energy waste in ventilation systems” by tracking the actual energy use in a sample of their 4 million m2 portfolio of buildings through on-line energy management tools. The project is not complete, but the key preliminary findings  described in this paper are: 

IAQ assessment in high performing buildings

            

Thermal comfort assessment in a sustainable designed office building

Thermal comfort improvement at the lowest energy consumption is a key issue when dealing with sustainability in buildings. An appropriate passive design is mandatory under those circumstances. Prior to construction, simulation tools help to make designs more sustainable. However, it is recognized a gap between real performance and the predicted one. This article presents the comfort methodology applied in an office building located in the north of Spain, characterized by a continental Mediterranean climate.

BIM & building simulation

Over the last three years the understanding, adoption and use of BIM has gained international momentum.

Hygrothermal analysis on the use of internal thermal insulation systems in Portuguese residential buildings

In Portugal, the external thermal insulation systems (ETIS) are nowadays a current technical solution in residential buildings, contrasting with the rarely used internal thermal insulation systems (ITIS). In this paper, a quantitative analysis on ITIS is done based on three hygrothermal façade requirements: interstitial condensations, thermal bridges, and temperature variations across the external wall. Computer simulation was used as research tool.

DEVELOPING LIFE CYCLE ASSESSMENT TOOL FOR BUILDINGS IN HONG KONG

Life Cycle Assessment (LCA) in many ways is a methodology which building industry is looking towardsto give the answers on how to assess sustainability of buildings. In Hong Kong, like many othercountries, its application is limited by the availability of credible assessment tools in the market. Thispaper provides the details on the processes and findings of a comprehensive study initiated by theGovernment to derive a LCA tool for the use of the local building industry, addressing on researches thatare needed to really make LCA part of the answer to sustainability assessment.
