LOG HOUSES!!! Why not...

             
  Log houses have a long history in North European countries and probably they were the first type of wooden house ever made. Thanks to modern technologies, today's log houses are very different from what they used to be and log buildings can be found in any size, ranging from very small cabins to huge villas/residences. Also, shape of logs is no longer rough and roundish but also oval or square logs are available making a each log house a unique product.
         

We have to agree that machined glue laminated timber square logs are really a beautiful construction material, capable of giving a very unique contemporary look while mantaining a traditional feeling.

From an engineering point of view those logs have very good properties as they can have wide spans, allowing for construction of very large internals spaces without need for much additional supports (posts, columns).

So, if today's logs have so nice qualities,

All that glitters is not Gold

Despite the solid feel of a machined log and its undeniably appealing look, there are areas where logs really do not offer much.
Here we give you three reasons why you should not build a log house:

1) Energy performanceThe U-value of a 300mm thick wall made of compact wood cannot be better than 0.40 W/m2K. For the same thickness, Qhaus double framed external walls reach an U-Value of 0.15 W/m2K... which makes them 2.6 times more Energy Efficient of a log wall of the same size.

Of course log house producers know the downside of their product and a few solutions have been developed in the attempt to solve the problem of Energy performance.
The most efficient solution comes in the form of machined glue laminated insulated logs. These logs contain insertes of insulation material which contributes to reduce the overal U-value of the log wall. Needless to say this solution is much more expensive than a standard machined log.
On top of the cost increase, introducing a "soft" material inside the log requires in general an increase of the overall thickness of the wall and, even in cases where smaller thickness can be used (one floor houses) the amount of insulation that can be packed into the wall is still way smaller than what you can pack into the same wall if it was made with timber frame... so, however you look at it, the thermal performance of a log wall is (and will always be) lower than the performance of a timber framed wall of the same thickness.

As a matter of fact log housing is finding its bottleneck in the most recent versions of building codes. As those become more and more strict in terms of energy performance, in many Countries today is simply not allowed to build residential houses with pure log technology (i.e. in Norway, Finland, Estonia and other Countries U-value limits are lower than 0.25W/m2K).

2) Air thightnessA log house is basically a large 3D puzzle when all the pices come in form of "bars". A timber frame element house is also a 3d puzzle but its pieces come in a much larger format.
As result, in a log house there are many more connections between its parts. if you measure the "lenght" of those connections in linear meters you come up to an interesting comparison.

For a sample square house of 100m2 (10x10m) you would have about 400m of connections in the log house version and just about 80m in the timber frame element version!
With a ratio 1:5 it is easy to understand that it is 5 times more likely to have air leaks in a log house than in an element one. Why air thightness is so important in a modern low-energy house is discussed in a previous article.

Again, as building codes become more and more strict, in some Countries it is not recommandable to build your house with log technolody as it would be a risk ensuring the required air tightness.

3) CostIt should be clear by now that, unless you live in warm climates where building regulations are still permissive, building a log house would pose quite a few challenges.
This means that if you go for it you have to take extra care to construction details. It might be necessary for example to foresee extra insulation inside the house and to use special products to ensure the complete sealing of all connections.

All this translates into extra costs that add up to the already expensive nature of glue laminated machined logs.
Wheather this cost is worth is up to you to decide but you must be aware that timber frame elements houses come generally at a better price point.

10 simple tips Dealing with Stress

Follow 10 simple tips to help manage and reduce your stress levels.

1. Avoid Caffeine, Alcohol, and Nicotine.

Avoid, or at least reduce your consumption of, nicotine and all drinks containing caffeine and alcohol. Caffeine, alcohol and nicotine are stimulants and so will increase your level of stress rather than reduce it.

Swap caffeinated and alcoholic drinks for water, herbal teas, or diluted natural fruit juices and aim to keep yourself hydrated as this will enable your body to cope better with stress. 

You should also aim to avoid or reduce your intake of refined sugars - they are contained in many manufactured foods (and even in savoury foods such as salad dressings and bread) and can cause energy crashes which may lead you to feel tired and irritable. In general, try to eat a healthy, well-balanced and nutritious diet.

2. Indulge in Physical Activity

Stressful situations increase the level of stress hormones such as adrenaline and cortisol in your body.

These are the “fight or flight” hormones that evolution has hard-wired into our brains and which are designed to protect us from immediate bodily harm when we are under threat.  However, stress in the modern age is rarely remedied by a fight or flight response, and so physical exercise can be used as a surrogate to metabolize the excessive stress hormones and restore your body and mind to a calmer, more relaxed state.

When you feel stressed and tense, go for a brisk walk in fresh air.  Try to incorporate some physical activity into your daily routine on a regular basis, either before or after work, or at lunchtime.  Regular physical activity will also improve the quality of your sleep.

You can also use Laughter Therapy to reduce stress hormones.

3. Get More Sleep

A lack of sleep is a significant cause of stress. Unfortunately though, stress also interrupts our sleep as thoughts keep whirling through our heads, stopping us from relaxing enough to fall asleep.

Rather than relying on medication, your aim should be to maximise your relaxation before going to sleep.  Make sure that your bedroom is a tranquil oasis with no reminders of the things that cause you stress.  Avoid caffeine during the evening, as well as excessive alcohol if you know that this leads to disturbed sleep. Stop doing any mentally demanding work several hours before going to bed so that you give your brain time to calm down.  Try taking a warm bath or reading a calming, undemanding book for a few minutes to relax your body, tire your eyes and help you forget about the things that worry you.

You should also aim to go to bed at roughly the same time each day so that your mind and body get used to a predictable bedtime routine.

4. Try Relaxation Techniques

Each day, try to relax with a stress reduction technique.  There are many tried and tested ways to reduce stress so try a few and see what works best for you.

For example, try self-hypnosis which is very easy and can be done anywhere, even at your desk or in the car. One very simple technique is to focus on a word or phrase that has a positive meaning to you. Words such as "calm" "love" and "peace" work well, or you could think of a self-affirming mantra such as “I deserve calm in my life” or “Grant me serenity”.  Focus on your chosen word or phrase; if you find your mind has wandered or you become aware of intrusive thoughts entering your mind, simply disregard them and return your focus to the chosen word or phrase. If you find yourself becoming tense again later, simply silently repeat your word or phrase.

Don't worry if you find it difficult to relax at first. Relaxation is a skill that needs to be learned and will improve with practice.

5. Talk to Someone

Just talking to someone about how you feel can be helpful. Talking can work by either distracting you from your stressful thoughts or releasing some of the built-up tension by discussing it.

Stress can cloud your judgement and prevent you from seeing things clearly. Talking things through with a friend, work colleague, or even a trained professional, can help you find solutions to your stress and put your problems into perspective.

6. Keep a Stress Diary

Keeping a stress diary for a few weeks is an effective stress management tool as it will help you become more aware of the situations which cause you to become stressed.

Note down the date, time and place of each stressful episode, and note what you were doing, who you were with, and how you felt both physically and emotionally.  Give each stressful episode a stress rating (on, say, a 1-10 scale) and use the diary to understand what triggers your stress and how effective you are in stressful situations.  This will enable you to avoid stressful situations and develop better coping mechanisms.

7. Take Control

Stress can be triggered by a problem that may on the surface seem impossible to solve. Learning how to find solutions to your problems will help you feel more in control thereby lowering your level of stress.

One problem-solving technique involves writing down the problem and coming up with as many possible solutions as you can. Decide on the good and bad points of each one and select the best solution. Write down each step that you need to take as part of the solution: what will be done, how will it be done, when will it be done, who is involved and where will it take place.

8. Manage Your Time

At times, we all feel overburdened by our 'To Do' list and this is a common cause of stress.   Accept that you can not do everything at once and start to prioritise and diarise your tasks.

Make a list of all the things that you need to do and list them in order of genuine priority. Note what tasks you need to do personally and what can be delegated to others to do.  Record which tasks need to be done immediately, in the next week, in the next month, or when time allows.

By editing what might have started out as an overwhelming and unmanageable task list, you can break it down into a series of smaller, more manageable tasks spread out over a longer time frame, with some tasks removed from the list entirely through delegation.

Remember as well to create buffer times to deal with unexpected and emergency tasks, and to include time for your own relaxation and well-being.

9. Learn to Say ‘No’

A common cause of stress is having too much to do and too little time in which to do it.  And yet in this situation, many people will still agree to take on additional responsibility.  Learning to say “No” to additional or unimportant requests will help to reduce your level of stress, and may also help you develop more self-confidence.

To learn to say “No”, you need to understand why you find it difficult.  Many people find it hard to say “No” because they want to help and are trying to be nice and to be liked.  For others, it is a fear of conflict, rejection or missed opportunities.  Remember that these barriers to saying “No” are all self-created.

You might feel reluctant to respond to a request with a straight “No”, at least at first.  Instead think of some pre-prepared phrases to let other people down more gently.  Practice saying phrases such as:

“I am sorry but I can’t commit to this as I have other priorities at the moment.”                          
“Now is not a good time as I’m in the middle of something.  Why don’t you ask me again at….?”
“I’d love to do this, but …”

10. Rest If You Are Ill

If you are feeling unwell, do not feel that you have to carry on regardless. A short spell of rest will enable the body to recover faster.

should man play God as to which animals to be killed?

This is the topic are been given by Madam Hanim to us to discussed.

From my opinion, as human either man or women should be good towards animals. The animals also a living thing and having its own family. The animals also have the right to life in this world. The awareness about extinction of animals should not be forget. Human should take a good care of the animals which can't do for its self. As a human, we should empower all to rise and stop culling the innocent animals. We are giving a brain and a good mind form our Creator, we should know the way to prevent the destructive of our biodiversity area. A lot of strategic and technology can be use, example, barren or control by minor surgery to  the animals which reduce the population. Or, its can be Exchange the animals to nation neighbors. Besides, build a building with environmentally friendly and plant more trees. theres many more!

People should think about extinction of animals not ourself. Stop being selfish and save many animals as you can!
