Any way, enough for the explanation and opinions about phenomenology in architecture, let's focus on the other related topic of mine, which is the Green Architecture. There are a few types of Green Architecture standards and certification systems around the world, for example the first green building rating system in U.K which established in the 1990s - Building Research Establishment's Environmental Assessment Method (BREEAM) and Leadership in Energy and Environmental Design (LEED) rating systems which is established by U.S Green Building Council in the year 2000. For Malaysia, Green Building rating system was introduced as Green Building Index (GBI) during January 3rd, 2009 at the Green Design Forum held at the Kuala Lumpur Conventional Centre.
Without further ado, let's proceed with the criteria of Indoor Environmental Quality based on Green Building Index. GBI is separated into few categories as below (click the picture to enlarge):
Note:
NRNC – Non-Residential New Construction | RNC – Residential New Construction | NREB – Non-Residential Existing Building | INC – Industrial New Construction | IEB – Industrial Existing Building

And whereby, this mean that there are different criteria and requirements of Indoor Environmental Quality (IEQ) for different types of buildings that I need to research on. But at the end of the day, I will compile with other researches regarding criteria of good IEQ for a better definition and understanding toward IEQ.
Below are 2 rating systems of GBI for the categories of Non-Residential Existing Building (NREB) and Residential New Construction (RNC) along with a design reference guide for RNC for my research.
Had been flipping through
pages of Ken Yeang's Ecodesign: A Manual for Ecological Design during my
journey of trying to sort out the definition of good IEQ. In the manual, he
stated that human thermal comfort zones are usually between
18°C and 24°C, but
this varies depending
on the relative humidity, which should remain between 30 and 65%.
Note: Relative humidity is a measure of the amount of water vapour in the air, of which 100% being saturated air. So within the above general limit (30-65%), the higher the relative humidity, thus, the lower air temperature required for humans to feel comfortable.
He also mentioned something that broadens my narrow minded seaweed brain that
of which the thermal comfort is not just about air temperatures and temperature gradients,
radiant temperature, air movement and ambient water vapour pressure, but
also about the amount of clothing worn by the occupants and the occupants'
level of activity.
Any way, I will wrap this post up with an
interesting news regarding Walkie
Talkie City skyscraper (also being renamed as Walkie
Scorhie) in London that had caused trouble to the environment around
the building due to its design. In a nutshell, designing an architecture is not
an easy job as we need to foresee and predict the outcome of
our design in order to prevent harm to the environment surrounding.
Enjoy the post :)
