ENERGY EFFICIENCY, HVAC, THERMAL COMFORT AND PASSIVE DESIGN

 

The central philosophy behind green building is the judicious use of resources in a manner that provides for man’s needs today without jeopardizing the ability of the future generation to fulfill their own energy needs.

The illustration above shows the authors’ conceptualization of how energy consumption is related to the use of HVAC equipment, which emanates from the need to maintain a comfortable indoor environment for the occupants in terms of indoor air quality and thermal comfort. The arrows indicate the two way relationship between the sections implying that any change in either of the sections bears significance on the others.  The authors’ argue that for energy consumption to reduce, passive design strategies must be adjusted to provide alternative sources of natural ventilation and thermal comfort. Such design strategies may include but not limited to design issues affecting building height, form, orientation, etcetra.

If we are going to continue building tall, we must figure out how to keep the energy consumption of such buildings within environmentally and economically sustainable limits. 

VISA EXTENSION - INDIA - PROCEEDURE AND GUIDELINES

If you live or work in India and you are looking for the proceedure for extending your current visa to afford you more time to complete your purpose of visit, then you may want to be careful with the website(s) you visit because there are lots of websites purporting to be visa and travel agencies who may ask for money where there MAY BE absolutely no fee - Yes, absolutely no fee.

For avoidance of any doubts, it is advised that anyone seeking to extend a subsisting visa within India should log on to the efrro official website and follow the simple steps specified on the visa extension form.

You will have to complete the application form for visa extemsion ( it is advised that the individual be present in India at the time of completing the application). The office would typically reachout to you via the email address you provided when registering on the frro portal. They may request additional documentation depending upon the nature of the susbsisting visa or where necessary.

Once your submitted documents are vetted and deemed satisfactory, you may be required to make some payment - especially in the case of a research visa. Note that there is no payment as of date for extension of other categories of student visa.

At every stage of your application, you may communicate with the frro office through the official website for any clarifications you may require. Be ware of predatory websites that may purport to be "accredited" agents of the frro office and may charge you a fee in the name of helping you apply for your visa extension. You can do it all yourself through your official account on the official  efrro official website

I wish you the best of luck!

Ph.D in India Vs. Ph.D in Nigeria - A Contemplation

 

Kosi Emmanuel Chukwujindu - During Ph.D in India - 2021

A PhD in any field of study is a rigorous self-undertaking that usually involves a lot of sacrifice on the part of the scholar.  The entire process leading up to the award of a Doctorate degree in any discipline is structured to ensure that the researcher makes a real contribution to knowledge in that field.

Often times, what we consider as the task at the beginning of our expression of interest to undertake a PhD research changes many times during the process and it helps to have proper guidance and a tailored program of work.

Speaking of proper guidance, it is expected that a Ph.D. research scholar must be guided by a supervisor who him / her self have earned their own doctorate in a related field. As a Nigerian who had enrolled for a Ph.D. study in Nigeria for six(6) years before deciding to leave the country to pursue the same degree abroad, my experience has been tough but I have learnt a lot for which I am immensely grateful.

In this post, I share the highlights of my experience as I can't help comparing conditions of study in both countries.

1. IMPROVED LECTURER'S ACCESSIBILITY 

In Nigeria, I had a hard time accessing my supervisor, he was of the Professor cadre and this meant he was only in school on scheduled days. If you didn't catch him on any of those, then you had to wait till the next time. It's different here in India. The Professors are always on seat and willing to discuss your work anytime. This was a real consolation to me because now I knew I only had to focus on the progress of my research and not bother about chasing the guide, since he's always on sit.

2. INFO/EXPOSURE TO LATEST RESEARCH TOOLS 

In my university in Nigeria, because the lecturers are not very accessible, it's harder to grab guidance on what best research tools are there and how best to combine them. There seems to be a certain "darkness" surrounding this and sometimes one would almost conclude it appears they are not very hands-on with the tools, themselves. This makes it tougher for research scholars in Nigeria to compete with their global counterparts. In India however, I found most research guides had practical current knowledge of research tools and software applications. We were literally thought the use of simulation softwares during the coursework part of our first year. 

This was a huge departure from my African background where if you learnt to use any software at all, you either enrolled for a private lesson at a private tutor place or you got a friend to show you privately, practical exposure to research/simulation software never came from my supervisors.

3. FEWER DISTRACTIONS

The biggest challenge I faced while enrolled as a Ph.D. research scholar in Nigeria was my own inability to focus on the research due to multiple distractions from other engagements such as my very demanding private practice, family, and lecturing. It was easy to drift off from the research when you had a thriving Architecture practice and a demanding lecturing job. I figured if I would make any headway with my PhD work, then I had to get away from all the distractions and the only way to do so was to leave the country to the greatest surprise of everyone, to go somewhere I can focus and finish off the research and probably get better supervision. I had to leave and I had to do so quickly!

I realized PhD research was in itself a full time engagement.

4. NO STUDENT LEVIES

In Nigeria, it was common to have the students levied by lecturers and the school for buying research related equipment for the department. One time we had to pay NGN5,000 each in order to procure a new set of public address system and projector for the department seminar room. The condition was that whoever did not contribute this sum, would not be permitted to present his work in the seminar room and ofcourse you could forget about getting any objective feedback on your work.

In India, I havent paid a rupee for anything departmental asides my tuition and exam fees. Everything is taken care of by the department and maintained by the school authority. This was also a relief.

5. HIGHER GLOBAL BEST PRACTISE AWARENESS

As they say, PhD degree is the highest academic degree obtainable and it is a globally recognized academic venture. Coming to India helped me refine my research to take a global perspective on the research questions I was trying to find answers to. 

6. BETTER QUALITY OF RESEARCH OUTPUT

For some reason Nigerian scholars abroad seemed to be producing richer quality of research output in many disciplines compared to our colleagues in Nigeria. This is a personal observation and I am still unsure why it is so. I think there is no pressure to compete international scheme of things at home in Nigeria, this has a negative effect on researchers ambitions. We settle for whatever can get us past the degree, even if its not relevant anywhere else. 

Also, I saw a metric somewhere that rated research publications from Nigeria, Kenya South Africa and the United States. In terms of economic impact of research, Nigeria scored zero. This points to the fact that in Nigeria, it's either the government does not rely on research output for making economic decision or the research output do not have any immediate or midterm economic relevance. This should be looked into.

7. EXPOSURE TO OTHER INTERNATIONAL SCHOLARS FROM AROUND THE WORLD

Doing research while surrounded by a diverse community of co-researchers and scholars naturally lifts your threshold for excellence.

A PERSONAL REALIZATION ON HUMAN DESIRES

Everything we desire in life comes to us at the right time if we truly need it and continue to apply the right effort with the right attitude (state of mind) towards it and if it is in the overall good of the universe. No matter how difficult or how far away it seems, at the right time it will come to us. 

As humans we have an insatiable desire for materials; cars, houses, clothes, food, sex, money etc - the list is endless. Sometimes we really need these things, most times we only want them because our friend does or because it makes us look better than others. Even when we have what we need already, we continue to want more, we imagine that we may run out of stock and so we are always trapped in an endless cycle of get this - get that, get this - get that, then get that, and then get this..

Sometimes when we have everything we desire, it hampers our spiritual growth. Some level of pain is important for us to understand joy. Other times when we don't have enough of what we need, it can also delay us from realizing our goals. Some level of stability is required for us to stay productive.

Balance is the key.

Understanding that nothing is a do-or-die affair and at the same time being able to set goals, work toward them and achieve them is what we need to get through life.

Food for thought: Why were the Isrealites instructed not to keep any of the manna from heaven overnight? They were to eat only their "daily bread" and not attempt to stock up any for the next day?

THE IMPACTS OF DUPLICATE OR OVERLAPPING PUBLICATIONS

Duplicate or overlapping publications is a situation where an author publishes the same body of work in its entirety or at least 2/3rd of the original work in multiple journals in order to increase his or her publication count.

Authors and researchers are usually caught in such situations due to pressure to publish or pressure to obtain certain privileges from their academic institution or grant agency. 

There are several drawbacks associated with this kind of unethical research conduct and they include: 

i).  Redundancy : 

this means that there are multiple publications with the same content and value, hence there is no real progress made, They are all saying the same thing. They do not help the future readers or researchers to make positive progress in subsequent works, they only keep repeating the same old knowledge into many places.

ii). Waste of Time : 

Such a practice amounts to a waste of the author's time as well as the reader's time. This is because research is dynamic and every day new knowledge is expected to emerge in every discipline. However, an author who takes to redundant, duplicate, or overlapping publications is actually wasting valuable research time which would otherwise have been channeled to discover new knowledge in the given research area.

iii). Confusion: 

Where multiple publications are made of the same literary content, it tends to cause confusion to the editors, reviewers, and researchers who struggle to identify if there is any new knowledge in the multiple publications. This ultimately leads to confusion because in the end they may be forced to retract some of the publications which may have already been cited by other researchers who did not realize that the works were duplicated or overlapping.

iv). Poor Literary Development of The Scholar :

When a research scholar resorts to duplicate or redundant publishing, he or she fails to develop his / her literary prowess and this ultimately leads to poor quality of researchers who may not be well fitted for technical positions in life and career paths where they belong.

v). Public Loss of Trust in the Parent Organisation : 

Any organization whose members are identified to consistently indulge in duplicate or overlapping publications will eventually lose the trust of the public or funding agency. It is therefore the responsibility of such organizations to ensure that they set up a research and publication ethics committee to vet and approve research works coming from members of their organization in order to ensure quality and guarantee adherence to ethical standards. Also, it is important for such organizations to retract any identified duplication or overlapping publications without recourse to who it is.

EXPLAINING THE USE OF PLAGIARISM SOFTWARE IN RESEARCH PUBLICATIONS

Source : clipartstation.com

A plagiarism software is a computer application that is designed to identify and quantify the extent of "external material" or "similarity to external material" that is contained in any given literary work. 

Plagiarism is a serious and unpardonable misconduct when it comes to academic publishing. It is a situation where an author presents part or whole of another authors work within his own work as if it originally belonged to him and goes ahead to publish same into public domain without making citation or reference to the origin or source of the material.

Because research is a continuum, it is expected that future researchers fall back on already existing body of knowledge for guidance and direction while conducting their own original research which will in turn lead to their own original new found knowledge. However ethical guidelines for research, mandates the researcher to make proper declarations wherever he has borrowed material from another author. This would ultimately contribute to and enrich the existing body of knowledge in the given research field.

However since it has been observed that researchers frequently fail to declare the borrowed contents in their works, the plagiarism software tool is applied while reviewing articles in order identify any such similarities between the current proposed publication and existing database of knowledge.

HOW IT WORKS

i). Submission : 

First the author submits his proposed literary work to a given journal or group of editors who call for papers or are desirous of compiling new knowledge in the given field of interest. The submission is required to be made in a soft copy (editable).

ii). Plagiarism check : 

The group of editors or reviewers usually have an in-house software application installed on their computer or available online where they pass the softcopy proposal through in order to check it for any possible similarities between existing database in the given field. The software is usually designed to read through the entire proposal and check it against the existing published works that have been catalogued in its memory. 

iii). Plagiarism quantification : 

The software usually presents the result of its check in terms of number of phrases, sentences and paragraphs that bear significant similarity to existing publications known to the software. This number of similarity occurrence is calculated a s percentage and usually only 10-15% of similarity is allowed. Literary works bearing similarity beyond 15% may require further human investigation to determine and establish possible plagiarism.

iv). Acceptance or Rejection : 

Based on the results from the plagiarism quantification by the software, the group of editors will either accept or reject the submitted proposal and will advice the author to make adjustments accordingly and resubmit for further evaluations.

Plagiarism detection software works as a safeguard for original content and serious writers, to protect their creative properties from literary thieves.

DO ONE THING, DO IT WELL - EXPECT NO MERCY

 

Life is simple, but we are overwhelmed by it on a daily basis. We seem to be on an endless clock that keeps moving whether we do anything or not. Life happens to us anyways, if we don't happen to it quickly enough. 

We don't know when we'll be done here, none of us knows his exit date, time or location, It can happen any moment, from the time you wake up in the morning to the time you lay down again in the night. There is no guarantee that everyone who woke up today will go to sleep again this night. Yet we make plans for 10, 15, 20 years time as if any part of it was guaranteed. We brag and carry our shoulders up as if we are anything. We look down on others and judge everyone else but ourselves. We refuse to help others on their own life journeys as if we were already done with ours.😃😃

Each of us have our unique challenges, its a full time job to figure them out and solve them on a daily basis. The lessons we learn while at it enriches us, the mistakes we fall into purnish us harshly and the clock continues tick - tack.. tick - tack 

For anyone who even bothers to think, it is crucial to figure out what you are doing here on Earth and what you want to leave for the next generation when you are gone. Of course, we already know that we don't take anything material from here when we pass on. We just go as light as we come, no baggages at least not physical. We have also come to understand that material belongings are perishable and only have relevance or value on this material plane. If this is the truthful case, then whatever we acquire here and now, cannot be ours forever. 

So what do we do? 

Our existential realities and conditions differ largely along lines of culture, religion, location and temperament. We are consistently under intense mental, physical, sociological, economic, cultural and religious pressure. Some people are lucky to figure out their way through these pressures and contain them, others are torn apart trying to even understand what is going on. 

We build institutions to help us calm the pressures, we join alliances (cultural and religious) to assure us that we are not alone while at it and ultimately we struggle to pay bills to continue living.  Money has become the biggest agent of control, It appears the more of it you have, the more able you are to contain your own pressures. Everyone strives to acquire more of it, in order to stand a chance to master our existence and liberate ourselves from suffering even if the acquisition causes pain to us and others.

What's more, even time has been equated to money. You spend time to get money and you spend money to buy time. It appears we are all rich in time, but not so equal on money.

Whatever is going on, we are in an intelligent system. The universe is a training school. There are lessons everywhere we look. Most of them come in disguise. We are not only living, but we are also learning. The natural laws of existence ensure that there is always a balance in the system. 

We don't know how for sure, but we can live each day as if it was our last. We can try to do one thing, do it well and expect no mercy!

IN THE WAKE OF AN UNDESIRABLE WAR - NIGERIAN INSTITUTE OF ARCHITECTS PROFESSIONAL PRACTICE EXAMINATION (P.P.E) VS. ARCHITECTS REGISTRATION COUNCIL OF NIGERIA ARCON (A.C.P)

The Nigerian institute of Architects N.I.A professional practice examination P.P.E held in two diets annually has just been concluded for the year 2017. No other exams organised by the institute will be held in the year 2017. In the wake of the growing impasse between the veteran examination conducting body and its national cousin; the Architect's Registration Council of Nigeria ARCON,  mixed feelings engulfed almost every examinee this year. The disagreement which has been described by many as everything including 'embarrassing' is rumored to be hinged on major administrative, tribalist and financial related prejudices. 

The Nigerian Institute of Architects, N.I.A set up in April 1960 has been the body responsible for pre-qualification of candidates and conduction of professional practice competence examination in the country, while the Architects registration council of Nigeria had hitherto relied on her for advice on successfully qualified candidates to be furnished with a practice license and a seal. This meant that once one scaled through the notoriously revered N.I.A exams, he/she was expressly admitted by ARCON and is deemed qualified to practice the profession of Architecture within Nigeria.

While this bi-laterral qualification requirement/proceedure had been questioned by many due to its rigorous nature, it had been accepted to be the 'norm' for over twenty (20) years.

Sadly, this amiable,

HOW TO FIX THE MISSING 'CONFIGURE SWITCHABLE GRAPHICS' OPTION ON AMD RADEON GRAPHCS CARD

I am an Architect and I use a HP pavillion G6-2304tx laptop with a dedicated AMD Radeon graphics card asides the basic Intel graphics card. The reason I requested a laptop with a dedicated graphics card was to enable me use Lumion (app) in rendering my Revit-Architecture models. I bought this PC back in 2013 when I had just rounded off my M.Arch degree from SRM University, Chennai and it was quite pricey at the time. Four(4) years down the line, the laptop, is still working perfectly, and has helped me land and deliver a lot of wonderful projects. But something happened. One day, one of the staff, accidentally pours water into the keyboard. We quickly rushed to a service centre where the Engineers opened the laptop up and tried to sun-dry. Four (4) straight hours of intense sunshine, was allowed before it was put back together, only it developed more problems.

First the keypad typed selectively, some keys wont work in upper case while others didnt work at all. But this was not a big deal, I just bought and replaced the HP keypad, and it was back in order. The major problem resulted when, I tried to work on a project on lumion as usual. I discovered serious graphic inconsistencies and when I checked I realised the 'configure switchable graphics'

option which usually shows up when I right-click anywhere on my desktop (as shown in the image) was missing.

I found a way to

AN ALTERNATIVE METHOD OF CONSTRUCTING THE CONCRETE FASCIA

posted by
Kosi Emmanuel Chukwujindu

Concrete fascia detail sketch by Arc Jude Uche; M.D /C.E.O Geometrix Consultants

Conventional Nigerian builders will construct a wooden/metal formwork to the shape of the desired fascia right about the roof edge/building wall, install the reinforcement bars and cast the whole volume with concrete. well this is the 'text-book' thing to do, right?

Unfortunately, The problem with this method is that it typically consumes much more materials (steel, concrete and woodwork) and when the building(s) is a large one or are numerous, it becomes simply impractical and time consuming.

Goodnews is; the Architects at Geometrix have over the years through experience under the leadership of the meticulous Arc. Jude Uche, developed an alternative method of constructing the concrete fascia. This method (as in sketch above) involves a pre-cast moulding of the fascia and a systematic fastening on exposed reinforcemnet bars sticking out from already existing roof beam using 6mm binding wires.

step 1: ROOF-BEAM:  the traditional roof beam which is done right around on top of the last course of block, is done, but the 4- reinforcement bars are not completely covered with concrete yet, the top two are exposed in order to receive the binding wire that will be used to fasten the pre-cast fascia.

step 2: PRODUCTION: moulders are vigrously moulding the concrete fascia on site using only cement and sand. (NB: this eliminates the need for reinforcement bars in the curved concrete fascia (CCF). they are allowed to cure and set, on the ground before cutting and lifting to avoid breakages. the final product is quite heavy. tiny openings are provided at intervals to allow for passing of binding wires.

step3: CUTTING TO SHAPE: once the concrete fascia has set (usually 36 hours after molding) it can then be cut into desired lengths according to the building corners. a typical piece would be 4' - 6' long. The cutting is done with a concrete sawing machine. the same type used to saw through block walls.

step4: INSTALLATION: After the cutting, two workers lift up piece by piece, insert the binding wires and with the help of in-situ scaffolding, climb and actually fasten the wires on the

two top exposed bars in the already made roof beam.

step 5: STRAIGHTENING & FINAL CASTING:

the straightening is done externally using a long plumb device and then held in place by wooden supports along the body of the wall. The binding wire that has been passed through openings on the pre cast concrete fascia is tied onto the top exposed bars tightly and is then covered with a second layer of concrete to hold it in place forever. 

step 6: JOINT TREATMENT: 

The final step is to 'tack' the joints properly with same binding wires and short pieces of wood which help prevent the different piecs from shifting until the final casting is done. they will be removed once the concrete sets. the thin openings at these joints will be covered with neat mortar and painted.

ADVANTAGES OF PRE-CAST CONCRETE FASCIA:

i). reduced volume of concrete.

ii). elimination of reinforcement bars in the fascia.

iii). reduction in overall weight of the fascia.

iv). same result as in-situ cast, sometimes even better!

v). If production begins early enough, Its installation takes less time.

vi). reduced cost of production due to elimination of materials such as reinforcement bars and wooden form work.

LIMITATIONS OF PRE-CAST CONCRETE FASCIA

i). shortage of trained staff, may delay work

ii). curing time may delay work where production is not started early enough.

HOW TO- RECOVER YOUR DRAWINGS FROM A FAILED EXTERNAL DISK

     we all love to hide those rare set-up files,Crack codes, Cad Accessories, wonderful rendered images, textbooks, commentaries, songs and movies in our 'safe sanctuary', the external Hard disk, usually to keep it away from colleagues or just other users in case you share a laptop with other people or just a safety precaution; as a back-up location, in case we ever lost information in the pc.

An external Hard-disk proves very reliable in all situations, In fact, people who do not have reasonable space on the PC hard-drive even have most of the important data on the external Hard disk, but what happens If it ever crashed. 

yes, they rarely do, but still, they fail sometimes!

If you have bad Hard disk ethics, such as removing it abruptly before it has finished writing or performing an action, it may be prone to a fatal failure in the near future. When this happens, your windows OS may run a checkdisk operation automatically and try to recover your data. The recovered data would mostly be with a unique file extension: .chk. ( a checkdisk file).

The files would most likely not appear in a

HOW DO YOU FEEL ON A DESIGN REVIEW DAY

 So how do Architects really feel just before a presentation..what am I thinking just before its my turn. Is it confidence, too much of it or less of it. is it fear of getting Bashed or is it calmness?
For most it is either of these sometimes and at other sometimes a combination of them, in a random order.

You are sure you have done your homework, but you are not sure how  the client would receive it. would it be ecstacious satisfaction or sad disappointment, would he throw arms around you in joyous praise of the work or frown at your beautiful ideas?
For me, its a mixture of those feelings. But what is common with us all is that before the meeting, we always feel confident.

Such was the case right here today.

The second review on the Abuja Satellite Township project, Spirits were high, we all peered critically at each others works.
however there seemed to be a dive in the mood after the review, egos had either been shattered or boosted!
Envy sets in, momentary depression happens some how you feel you have been misjudged or under-graded.
But you take a resolve to go back and do more work and bounce back stronger!!
