International Building Codes, Sustainable Design, Ventilation

Why Are Ventilation Codes Important For Sustainability, Especially in Asia?

Sustainability is a hot topic these days. There is an incentive to go green in every corner of the marketplace, if not for the sake of combating climate change, then for the financial advantages, or simply to keep up with modern fashion trends. The building industry is no exception.

Buildings contribute approximately 40 % of global energy usage per year, which puts them among the top priorities for developing and implementing sustainable practices. To quote Laustsen (2008), “the implications of such potential reduction [in the energy use by buildings] should not be underestimated, as the scale of energy efficiency in buildings is significant enough to influence security policy, climate preservation and public health on a national and global scale.” Continue reading

How Are International Building Codes For Ventilation Being Adopted in Asia?

International building codes, the documents that regulate every step of a building’s life; from design and construction, through to energy efficiency and the quality of the air you breathe inside. International building codes affect almost everyone every day. Continue reading


Ventilation System Designs

This blog will look at ventilation system design and its applications. Here are a few definitions that will be used quite often in this blog post:

    • Fresh air duct – supplies fresh air to the ventilation unit.
    • Supply air ducts – distribute the fresh air from the unit to the rooms.
  • Exhaust air ducts – conduct indoor air to the ventilation unit, which uses the thermal capacity to warm incoming fresh air, as necessary.
  • Waste air duct – removes exhaust air by conveying it from the ventilation unit to the exhaust pipe on the roofs.
  • Mineral wool – refers to both glass wool and rock wool. Mineral wool does not burn or rot.
