#DYK: Cool fun facts about air-conditioning you probably didn’t know

My earliest memory of experiencing the euphoria of air-conditioning was in my folks (19 something) orange Volksie Kombi on our annual trip down to Kei Mouth on the Wild Coast.

 

This luxury was provided via a foot pedal that opened a hole in the side of the kombi. Problem was the temp was controlled by the temperature on the outside, though you could increase or decrease the ‘fan’ strength depending on how hard or softly you pushed this pedal.

     

I suppose the earliest air-conditioning for man happened in Egypt some 5000 years ago between 3000 and 30 BC. where slaves were bought and ‘plugged-in’ to provide cooling through brilliantly decorated hand fans often sporting feathers.

Mother Nature has been using innovative ways of combating heat for millennia.

Take the termites for example:

Termites use an intricate system of channels, chimneys and air pockets, to keep their mounds cooled even in the hottest environments. The reverse also applies, keeping the interior warm in the coldest of nights

Biomimicry

There are many examples of biomimicry in the air-conditioning field. (Biomimicry is an approach to innovation that seeks sustainable solutions to human challenges by emulating nature’s time-tested patterns and strategies.)

  • Ventilation Inspired by Termites
  • Counter current Heat Exchange Inspired by Birds
  • Moisture Absorption Inspired by Ticks
  • Efficient Fans Inspired by Tornadoes and Whirlpool
  • Efficient Fans Inspired by Whale Flippers

 

Air-conditioning plays a major role in controlling our environment and keeping us comfortable and healthy. It enables us to inhabit extreme environments and provide comfort and safe living conditions. It not only controls the temperature, but also can manipulate humidly to remove pathogens.

Some interesting facts:

  • In 1736, the English House of Commons was cooled by a seven-foot, hand-cranked “blowing wheel,” which acted as a giant fan. The man at the helm of the crank was called the Ventilator.
  • The first ice-making machine was patented as early as 1851, but the invention was smothered by American ice interests for decades due to an extensive network that stored and transported ice from northern regions.
  • 1902: Willis Carrier invented the first air conditioner reminiscent of today’s models. The machine de-humidified and cooled the air so paper would stay smooth and the ink fresh. This machine had the ability to cool air significantly and lower humidity levels by nearly 55 percent.
  • Herbert Hoover was the first President to enjoy air conditioning. He spent $30,000 to install the system in the oval office, just after the start of the Great Depression
    At 130,000 tons, the (Integrated District Cooling Plant) IDCP is the world’s largest district cooling plant used to cool the island of Qatar.

 

The South African Aircon & Refrigeration Industry is vibrant and involved in many varied and interesting building avenues. This industry will continue expanding exponentially as the development of rural areas increases.

To date there have been over 250 Air-conditioning tenders published this year.

L2B Blog: Epic Air Conditioning Fails

posted in: General 0

As we all know the winter season can be a chilly “bordering on freezing” climate that has its ups and downs, the last thing we need to be worrying about is our air conditioning unit failing on us.

Being office bound, we need to ensure ourselves as well as our colleagues are comfortable in order to create a smooth working environment. So I have emphasized on the most common air conditioning problems that we could experience and a solution to the problem.

   

PROBLEMS / SOLUTIONS:

  • Having an air-conditioning unit on, whether it be at your office or at home, you should ensure that all doors and windows are closed in order for the air-conditioning unit to operate to its full potential.
  • Lack of maintenance on your air conditioning unit can result in permanent damage to your unit. You should ensure that you hire the correct air-conditioning technicians to service and maintain these units. Correct maintenance can ensure less chance of a breakdown. Ensure that you get your air-conditioning units serviced on a regular basis to ensure that dirt is removed off the compressor so that your unit does not fail prematurely.
  • Poor installation of your air-conditioning unit can result in the lack of air-flow and leaking ducts (Piping that allows for distribution of airflow). Having a lack of air flow will be established immediately as you will not experience the satisfaction of having your air-conditioning unit switched on. Always ensure that you hire an accredited company that will be installing your units as poor installation can give you endless problems which may result in you having to replace your air-conditioning unit.
  • If you are experiencing a leaking air-conditioning unit, this could be from the lack of or too much refrigerant within your unit. Please take note that if you conclude that the refrigerant is the problem, do not attempt to just fill it up or release some refrigerant as the manufacturer of the air-conditioning unit specifies exactly the required amount of refrigerant that should be in the unit in order for it to operate correctly.
  • Finally, if you have a room or office air-conditioning unit and it is humid outside, on a regular basis check that your condensate drain is draining correctly and there are no objects that are blocking the drainage, this can also affect the running of your system.
   

 

TIPS:

  • Ensure you hire the correct team in order to keep your air-conditioning units in great condition.
  • Do not be left stranded in the cold or the heat due to air-conditioning units that have failed!!

Did you Know #DYK: Sick Building Syndrome (SBS)

Sick Building Syndrome (SBS)

Sick Building Syndrome also known as SBS is a medical condition that often comprises of a range of non-specific symptoms that occur in the workplace or building and its occupants. This syndrome causes the occupants to have a feeling of ill health which in turn causes a ripple effect starting from absenteeism to a decrease in workers productivity. As a result, SBS is fast becoming a major occupational hazard. Therefore all factors such as cause, management, preventative measures and employer responsibility need to be ascertained and looked at.

Symptoms:

  • Headaches
  • Respiratory problems
  • Nausea
  • Flu like symptoms
  • Fatigue
  • Poor concentration
  • Skin irritations
  • Increase in asthma attacks

Risk factors:

  • Chemical contaminants
  • Biological contaminants
  • Inadequate ventilation
  • Electromagnetic radiation
  • Psychological factors
  • Poor lighting, absence of light & humidity

Prevention & control:

In order to minimize or completely prevent SBS it is important to ensure the building has good ventilation, if an air conditioning unit is used it is important to keep it well maintained at all times and ensure that ventilation standards are met, ensure intake vents are not located in areas that could be close to large amounts of traffic.

Products below should be checked for safety:

  • Paint
  • Adhesives
  • Pesticides
  • Cleaning agents

Other contaminants that need to be watched for:

  • Mold
  • Insect & bird droppings
  • Stagnant water (this breeds bacteria, viruses & fungus)

To reduce the effects of using equipment that omit electromagnetic radiation, it is important to correctly ground wiring to reduce magnetic fields that affect your health.
High stress levels and long working hours can affect one’s ability to remain healthy and productive. Stress can weaken your immune system and psychological wellbeing.
There is a greater link of SBS in air conditioned buildings than those that are naturally ventilated.

Employer’s responsibility:

  • Carry out surveys with your employees
  • Ensure all cleaning machinery is in good working order & that filters are clean
  • Ensure cleaning agents are being used correctly & stored correctly
  • Ensure the ventilation unit is well maintained
  • Ensure the intake for the ventilation system is checked
  • When possible, use natural ventilation
  • Ensure staff schedule their work properly to ensure less stress
  • Ensure staff take regular breaks and step away from their work space
  • Encourage staff to eat healthy and get regular exercise

L2B Blog: Visions of the future from the architectural past

Visions of the future from the architectural past

When you look at a building, what do you see? I see bricks, some windows, a door or two, oh, and we can’t forget the roof. I am sure that is pretty much what everyone else sees. But when I was given the task of writing this blog, I couldn’t find anything on visions of the future from Architectures past besides the thoughts and visions of what the future might look like with flying cars and buildings in the air floating around (Ok, maybe not to that extent, but you get the idea). With a pounding headache and the confusion lingering, I was forced to take a deeper look into what was handed to me.

A light bulb appeared and low and behold, bam! The idea popped into my mind. I started to think a little out of the box. As the searching started I was amazed at what I discovered, who knew that there is more to a building than just bricks, windows, doors and a roof. Confused? Let me shed some light…

When you look at a building there is more than what the eye can see. There is a past, a story to be told. If I had to write about each and every building, we might be dealing with the longest blog known. Instead I have isolated 3 buildings to tell their story…

 

1. The Dresden Fraunkirche ( Church of the Lady)

The Dresden Fraunkirche is a Lutheran church in Dresden, capital state of Saxony, Germany, first built in the 11th century in a Romanesque style. The first Frauenkirche was torn down in 1727 and replaced by a new and larger church. The church’s most distinctive feature was its unconventional 96m high dome, called ‘die Steinerne Glocke’ or “Stone Bell”

 

 

 

 

 

 

 

 

 

 

(Frauenkirche, between 1860 and 1890)

 

The destruction of the Frauenkirche took place on 13 February 1945, when Anglo-American allied forces began the bombing of Dresden. The church withstood these attacks for two days and nights and held long enough for the evacuation of 300 people who had sought shelter in the church. The dome finally collapsed on 15 February. The pillars exploded and the outer walls shattered and nearly 6 000 tons of stone plunged to earth.

 

During the last months of World War II, residents expressed the desire to rebuild the church, however reconstruction came to a halt due to political circumstances in East Germany. Due to the continuing decay of the ruins, Dresden leaders decided in 1985 to rebuild the Church of Our Lady. The project gathered momentum as hundreds of architects, art historians and engineers sorted through the thousands of stones, identifying and labelling each for reuse in the new structure.

 

Reconstruction proceeded in February 1992 and a rubble-sorting ceremony started the event in January 1993 under the direction of architect and engineer Eberhard Burger. The foundation stone was laid in 1995 and stabilised in 1995. In 1996 the crypt was completed followed by the inner cupola in 2000. The exterior was completed by 2004 and the exterior painted in 2005. The intensive efforts to rebuild this landmark were completed in 2005, one year earlier as planned and in time for the 800-year anniversary in 2006.

(Frauenkirche at night)

 

2. The Reichstag Building

The Reichstag building is a historic edifice in Berlin, Germany which was constructed in 1871 to house the Imperial Diet of the General Empire.

(Reichstag Building, August 1932)

 

The building was opened in 1894 and housed the Diet until 1933, when it was severely damaged after it was set on fire. The building fell into disuse after the World War II.

(Reichstag, postwar. June 1945)

 

The ruined building was made safe against the elements and partially refurbished in the 1960s. Only after the German reunification on 3 October 1990, did the Reichstag undergo reconstruction led by Architect Norman Foster

During reconstruction, the building was almost completely stripped, taking out everything except the outer walls. Respect to the historic aspects was one of the conditions stipulated to the architects so that traces of historical events were to be retained in visible state.

Reconstruction was completed in 1999 and is the second most visited attraction in Germany. The building houses a huge glass dome that was erected on the roof as a gesture to the original 1894 cupola.

3. Last but not least, the demise of the next buildings, shattered America and brought the world to a standstill… the World Trade Centre (The Twin Towers)

At the time of their completion the Twin Towers were the tallest buildings in the world. On 20 September 1962, the Port Authority announced the selection of Minoru Yamasaki as lead architect and Emery Roth & Sons as associate architects. The original plan was for the towers to only be 80 stories tall, however, to meet the requirements of the Port Authority to have 10 000 000 square feet of office space, towers were eventually 110 stories tall. Demolition work began on 21 March 1966 to clear thirteen square blocks of low rise buildings. Groundbreaking took place on 5 August 1966. On 4 April 1973 the Twin Towers opened.

 

About 50 000 people worked in the towers with approximately 200 000 additional visitors passing through on a typical weekday. On 11 September 2001, the world came to a standstill when terrorists hijacked American Airlines and deliberately crashed into both the towers. It was estimated that approximately 17 400 occupants were in the towers at the time of the attacks and 2 977 people died as a result.

 

During the following years, plans were created for the reconstruction of the World Trade Centre which is now known as the World Trade Centre Memorial and Museum. They commemorate all the victims that were killed on 11 September 2011, including the names of 6 people who were killed in the World Trade Centre bombings in 1993. Construction began in August 2006 and despite many delays, the opening of the memorial took place on 12 September 2011, one day after the 10th anniversary of the terrorist attacks. The names of the victims are inscribed on 76 bronze plates attached to the walls of the memorial pools. Below is the transcript of ‘The Memorial Mission’:

 

‘The Memorial Mission’

‘Remember and honour the thousands of innocent men, women, and children murdered by terrorists in the horrific attacks of February 26, 1993 and September 11, 2001.

Respect this place made sacred through tragic loss.

Recognise the endurance of those who survived, the courage of those who risked their lives to save others, and the compassion of all who supported us in our darkest hours.

May the lives remembered, the deeds recognised, and the spirit reawakened be eternal beacons, which reaffirm respect for life, strengthen our resolve to preserve freedom, and inspire an end to hatred, ignorance and intolerance.’

 

 

With a new outlook on buildings, always remember that just like each and every one of us, we all have a story to tell. A past, a present and a future.
