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

Uponor Inaugurates Factory and Sales Office in China

Uponor Corporation is strengthening its foothold in Asian building markets by officially opening its first manufacturing facility in Taicang, China today.

As the company’s 14th manufacturing facility globally, the new facility started operations at the end of 2016, and is presently fully equipped and serving customer orders. The factory will serve as the base for the production of Uponor’s globally leading sustainable plumbing solutions and energy-efficient heating and cooling systems for the new residential and commercial building markets in China.

The Best Types Of DOAS For Humid Climates

The maintenance of high indoor air quality (IAQ) is important in all buildings – the health and safety of the occupants require that the air is circulated to remove contaminants, and provide fresh air. The importance of IAQ becomes particularly evident when you take note of the fact that most people spend 80 – 90 % of their time indoors.

However, the conditioning of incurrent air into buildings can be tricky under some climate conditions, when treating incurrent air to meet standards for circulation around the building can be highly energetically and monetarily expensive. This is perhaps at one of its most pertinent in areas that are very humid (and often hot as well). For example, a study of commercial buildings in Thailand, a hot, humid region, showed that air conditioning could comprise 50 – 60 % of energy usage. Continue reading

Understanding Energy Recovery Wheels

Many buildings need a constant exchange of clean air from outside with contaminated air generated within the building. This is because the maintenance of particular indoor air conditions is vital for the health and comfort of the occupants. However, this creates a problem, because often the temperature and humidity requirements of the inside air are different than those found outside. The incurrent air needs to be altered to be suitable for traveling into the building, which can demand lots of energy – in fact, cooling comprises a huge portion of energy usage worldwide. This is where energy recovery wheels (ERWs) come in. Continue reading

The Impact Of Climate Change On Green Building

There’s a lot of information floating around about climate change. Most people know it has something to do with industrial pollution, changing weather and an increase in the ‘green’ trend and they kind of get what Al Gore was trying to say in An Inconvenient Truth.

In a nutshell, climate change occurs when long-term weather patterns are altered — for example, through human activity. Global warming is one measure of climate change, and is a rise in the average global temperature. A large proportion of the pollution that attributes to climate change comes from commercial buildings. This post will look at the impact of climate change on green building.  Continue reading

PE-XA Tubing, Radiant Cooling

Why You Should Use Pex-A Tubing Rather Than Copper For Your Next Project

Crosslinked polyethylene (PEX) was first prepared in the 1930’s by irradiating the extruded tube with an electron beam. Since its initial introduction, PEX has become increasingly popular in the construction industry. Pex-A tubing has become more popular than copper in recent times due to its many advantages.

In the last few decades, the manufacturing process has improved significantly. There are currently three methods for producing crosslinked polyethylene (PEX) tubing. Continue reading

Radiant Cooling Mythbusters – Dispelling The Myths About Radiant Cooling

Radiant cooling is a technology that most architects and engineers are familiar with. For those of us living in cold or temperate climates, many of us may experience its effects on a daily basis. Yet, most know relatively little about the details of radiant cooling solutions, and just how effective it can be in maintaining thermal comfort in all manner of building types. Most are misled by the myths about radiant cooling out there.

As with most things we know little about, we usually fill the gaps in our knowledge with assumptions or half-truths to try and get a complete picture. In this blog we’d like to set the record straight by demystifying some of the myths about radiant cooling. Continue reading
