What is Smoke Control Rational Analysis and Why is it so Important?

fire alarm system

Smoke control rational analysis is a research program that intends to explain the purpose and functions of smoke control. It is needed to verify the smoke control systems to be used, the system equipment, and operations methods.

What should be included in a Smoke Control Rational Analysis?

No set document is used for smoke control rational analysis. The smoke controls rational analysis should accompany the scheme construction documents. Every AHJ (Authority Having Jurisdiction) might allow or require something different. However, an IBC (International Building Code) requires the smoke control rational analysis to include the following:

• The construction methods to be used.

• Systems types explanation.

• The supporting system.

• The methods of operation.

• Small-scale drawings should be available that show the zone designation and boundaries.

• Exit enclosures pressurized, sub zones or passive zones should also be well shown on the drawings.

• The Rational Analysis can be part of the overall document, such as the Fire Protection or Smoke Control Report, depending upon the local jurisdiction essentials.

• Rational Analysis should have information on the equipment and how it will be tracked.

• Dampers to keep track of and which positions are monitored.

• The door should be observed if required.

• How fans will be separated between uses.

• The design criteria for time to display the various status indications.

• Each zone description and designation.

• The smoke control method and type.

• The system activation system.

• The system configuration description.

• A description of elaborating whether the system shall be dedicated or even non-dedicated.

• The pass/fail criterion for each system.

• Devices and equipment to be monitored.

A well-prepared smoke control rational analysis is essential to help avoid a lot of problems.

Lack of thorough documentation can lead to a lot of risks, such as:

• Problems during construction

• Project delays

• Cost overruns

• Creates risk concerning life safety

The smoke controls rational analysis documents the basis of the smoke control design. It goes down to gaining approval from AHJ to inspect the building to survey overall fire safety programs’ overall protection. Then there will be facilitation and organization of the commissioning process and also taking part in a third-party review.

This report on the smoke control rational analysis is very important since it will guide the contractor, design team, building inspectors, and the commissioning officer.

What is a Smoke Control System?

It is a masterminded system that employs a combination of inert barriers, mechanical devices, and automated detection and suppression to restrain the flow of smoke from the crisis zone to the various smoke zones. A well-outlined smoke control system should restrain the smoke passage into sections that lead to the designated secure zones in a property or even the exits.

To achieve this, a smoke control rational analysis is a significant requirement to put into consideration. The smoke controls rational analysis justifies the smoke control systems to protect occupants from the smoke caused during unwanted fire breakouts.

On the other hand, smoke control systems are designed to assist during an actual smoke event. It is created to restrict and get rid of the flow of smoke while the fire burns. Thereby, smoke control systems help the tenants to have a reliable escape route. Primarily, it does this by prolonging the amount of time a property’s occupants have to leave safely without being overwhelmed by effects related to the smoke.

To do this productively, it is ordinarily necessary to evaluate the amount of smoke generated and how much smoke will be produced. Therefore, the smoke control system plan requires careful deliberation and qualified designers to define the most practical solutions.

The smoke control rational analysis should also include the following topics:

Stack effect; this is the flow of air resulted from thermal differences. Hot air is less dense than cold air. Therefore, the smoke control rational analysis should ensure there is a stack effect in a building. The flow of outdoor-indoors air should be a continuous cycle. Without a plan, stack effects can lead to some severe upshots.

• Temperature effect on fire; the local outdoor and indoor design temperatures should be thoroughly calculated to ensure that the smoke plume will act accordingly as predicted in the analysis.

• Wind effect; wind affects the rate of intensity and spread of the fire. The smoke controls rational analysis should document the wind’s impact from all angles to ensure the system performance is sufficient.

• HVAC systems; systems provide thermal support and adequate indoor air quality. The smoke controls rational analysis should also include constant air-conditioning throughout the cells.

• Climate; the building’s local conditions should be well researched to ensure the smoke control system is effective.

• Duration of operation; the smoke control rotational analysis should tell the duration that the smoke control system will operate.

The Methodology of Smoke Control Rational Analysis.

The smoke controls rational analysis is a research program. It aims to illustrate the purpose and functions of the smoke control system. The analysis has several steps, such as goals and much more, as we will discuss here. Smoke control rational analysis investigates the property and purpose of smoke control systems by studying the environment structure.

• Goals

The smoke controls rational analysis specifies precisely what set goals the smoke control system will achieve. It will analyze what the smoke control system is, how it operates, and the gains of installing the smoke control system. These objectives will help responsible people like managers, building owners, and fire engineers understand vividly why the smoke control system is so crucial to protecting buildings, life, and stocks. The smoke controls rational analysis will have all these outlined. Before we delve further into other importances, the main goals of the smoke control system are:

1. Protect the exit routes for tenants to vacate safely and ensure fire effects do not limit them.

2. Help the firefighters in the building to tackle and find the cause of fire quickly

3. Protect machines and stock loss of production capacity

4. Reduce the dangers of blasts and the building roof from collapsing

• Environment

The smoke controls rational analysis should highlight a precise design of the environment whereby the smoke control system will be adapted. The smoke control system’s design plan holds the smoke in a given smoke zone. It provides a secured environment for the time required to safely evacuate or relocate all occupants within a given smoke zone.

• Computational Limitations

Smoke control rational analysis should make the least hypotheses concerning computational limitations. It’s an anytime algorithm that can give a current best solution at any given time, but the algorithm can produce much better solutions if added more time. Often, computational resource limits can prevent getting a solution as quickly as possible. Here, an agent can either provide a reason about the most outstanding action to take without

considering the limited computational resources or decide on finding the best action given its computational limitations.

• Optimization

The analysis should determine the optimal behavioral function of the three points addressed above. The IBC needs a special inspection for smoke control systems. Testing smoke control systems will intend to make sure each component of the project is working correctly. The smoke controls rational analysis should ensure that they work well together following design purpose and the system’s governing codes. The system must detect smoke events, prevent smoke circulation and migration, and ensure proper property spaces’ pressurization.

• Data

The smoke controls rational analysis should review the empirical research to examine whether or not the behavioral function predictions are confirmed.

• Iteration

Repeat, iteratively polishing up the theory.

Why is Smoke Control Rational Analysis Important?

The analysis will help make decisions that are backed by data. It is efficient for smoke control systems during the installation as it will eliminate inefficient processes. Smoke control rational analysis is one of the most critical processes that a smoke control construction can leverage to make the right decisions.

There is virtually no company or business in this age and generation that does not demand rotational analysis of their collected data to make the right decisions. Significant smoke controls rational analysis is a profession that can be applied to bankroll, local business, medication, healthcare, and still in the universe of sports. It is unlimited.

Improve People’s Lives

Smoke control rational analysis will aid to improve the quality of living for the occupants you support: Enhancing quality is literally among the motives organizations should always use data. By enabling you to scale and take action, an adequate rational analysis can equip your smoke control system construction to promote the quality of people’s lifestyles.

Be Strategic in Your Approaches

Smoke control rational analysis improves efficiency. Sufficient data analysis and collection allows you to put limited resources wherever they are highly needed. The analysis will further support smoke control rational analysis to determine which sections should be prioritized.


Smoke control systems are very sophisticated combinations of architectural, electrical, and smoke protection components. Just in case they are not properly managed and designed, they often become a crisis to implement. They as well get very costly. Moreso, it is barely hard to make the system function as required if there is no smoke control rational analysis.

Close collaboration among the mechanical engineer, the fire protection engineer, and an architect can also smoothly execute the project. The complexities of the recent properties have created circumstances that only a smoke control rational analysis can hack. An exceptional input is required to ensure the design teams do not break keep to their budget while constructing an effective smoke control system that is approvable, robust, and functional as well.

Why Concrete Showers are Amazing and You Should Get One

amazing concrete shower

Concrete bathrooms are a growing trend in modern homes. If you plan to upgrade your bathroom, a concrete shower can be a sure bet. It can be colored with stains or stenciled to look like tiles. Besides, you can add integral pigments to make the concrete look black as granite or white as porcelain.

Also, an existing tile shower can be resurfaced with concrete to save time and money. And if you’re worried about the concrete absorbing moisture, you can use a waterproofing sealer.

Some of the reasons why you should install concrete showers are:

  • They are easy to clean
  • They have no grout joints
  • You get unlimited design options


While the aesthetic quality is part of the trend, you cannot underestimate the durability of a concrete shower. When the rustic surfaces are combined with ultra-convenient bathroom mixes, you can create a customized good-feel bathroom. So, if your concrete shower is installed by a professional, it will stand the test of time.

Concrete is a cost-effective material, so once you install it, you don’t have to replace it in decades. This doesn’t apply to other materials that require maintenance.


Let’s face it: water is a destructive element. But here is the thing – most bathrooms require frequent maintenance. After exposure to moisture for a long time, they expedite wear and tear.

A well-designed shower cannot succumb to the effects of water. And if cracks appear, you can catch them early. In most cases, these repairs are inexpensive. If you want to keep moisture at bay, you should monitor the concrete elements in your bathroom.

A basic concrete may cost you $2-6 per square foot. If a cement-board underlayment is used, you should expect to pay an extra $2-3 per square foot.

Ease of cleaning

A concrete shower requires periodic cleaning. It’s not prone to staining but even if it stains, you can remove them early – basic cleaning and sweeping will keep the shower clean.

Unlike other shower floors, no special washing regiments are required. Even better, concrete can withstand harsh cleaning chemicals, and there’s a lower risk of discoloration. If this doesn’t concern you, you should clean the shower using detergents that suit you best.

concrete shower design

There’s a design to match every home

No matter the style you want, you’ll find something that suits your bathroom. These days, concrete is a popular material in many homes. Depending on your needs, you can mix concrete with wood or any other material. Furthermore, you can mix concrete with vivid colors.

Concrete is minimal, modern, and sometimes colorful. Besides bringing the interior design aesthetic, modern concrete finishes can transform a home into any style. Although concrete is an inexpensive material, it gives your bathroom a luxurious feel, and it’s not limited to styles either.

Whether you’re looking for something more industrial or kid-friendly, you can do a lot with concrete. Also, the masculine feel of cement can be balanced to give your bathroom a warm texture.

Sometimes, the bathroom can be slippery or cold. But you can address these issues with ease. For instance, you can create your concrete builder with the elements you need. But before you choose a concrete shower that suits you best, you should consider the brilliant ways you want to enhance your home.

There’re many unique and inspiring ideas ranging from luxurious bathrooms to cost-effective makeovers. Some of the things you can do include:

One way you can keep the bathroom feeling fresh and tranquil is to use the natural light. For example, you can install a large skylight or keep window dressings breezy. Natural light can also be a good mood enhancer as you start your day.

Terrazzo Concrete

With Terrazzo, bits of concrete is left to give a beautiful pebble surface. You can choose the style and color variants that suit your bathroom. And because terrazzo concrete is cost-effective, you can choose a style that matches the walls and floors. Some of the benefits of terrazzo concrete are:

  • You get many architectural colors and design options
  • Low maintenance
  • Durable
  • Easy to clean

Balance surfaces

The key to achieving a great shower is to balance the surfaces. If you don’t use the right accessories, the concrete can get too cold. But you can bring some warmth by using brass fixtures.

Statement concrete feature

One way to incorporate the industrial trend of concrete is by minimizing the concrete to one element in your bathroom. This will not keep the bathroom too fresh but also impacts the chosen feature like a basin.

Use brown tones

A concrete shower can be quite masculine, so you should introduce natural shades of brown. You can also introduce a large clay basin to bring a touch of femininity.

Balance with brick

Another way you can incorporate warmer shades in your concrete shower is by balancing concrete with bricks. And depending on the statement you want to make, you can leave the bricks unpolished.

Go boho

Did you know that you can mix different genres in the bathroom by adding a splash of color and fun to bring a bohemian style?

Add organic pendant lights?

You can add pendant lights in the bathroom to get a flawless design in your space. A concrete bathroom flooring will ensure you get a gorgeous feel.

Luxurious marble

If you want to maintain a moodier shower to add glamor and luxury, you can introduce dark marble. Alternatively, you can lighten the bathroom with shades of nude and white marble. So, no matter the style you want to achieve, you can’t go wrong with luxurious marble.

Rough it up a little

Not all concrete needs to be polished. Therefore, you can edge your bathroom by ensuring it’s a little rough. Perhaps, you can match the trend in your home.

Paint it

While most people think that grey color is perfect for your bathroom, you can also add a new element. If you want to bring a more modern style, you can go for a matte blush basin. If you choose to go for the dark side, you should ensure there’s enough natural light. Also, think candles, skylights, or textured toweling.

Floor pebbles

You can pair concrete with a pebbled floor to create an indoor-feel in your bathroom. The pebbles will not only feel greater under the feet but also pair beautifully with the cement. What’s more, pebbles add texture to create a natural space.

In-build shelving

You can add shelves in your concrete shower to maximize storage. Besides, your bathroom will appear elegant and sleek to save on expensive cabinetry costs.

Playful geometry

Did you know that you can add a bit of geometry to a concrete shower to create a playful finish? For instance, you can round out an edge that appears sharp.

Concrete floors are environmentally-friendly

If you want your bathroom to be environmental-friendly, you can’t go wrong with concrete showers. They are trendy, stylish, and require low maintenance. But here is the thing. On the eco-friendly scale, concrete is ahead of the game.

Since concrete is made of natural materials, you can introduce natural pigments on patterns. It gets better if you use natural colors instead of artificial colors. Of course, natural colors won’t fade with time. You can also get some of the oldest encaustic tiles that bring a unique style to your shower. Also, concrete can be hardened to make them more energy-efficient.

Once you install concrete in your shower, you could plaster it. You can also add lime and gypsum or any other material that doesn’t emit volatile compounds.

Another way you can make your bathroom more environmentally-friendly is by making use of fly-ash content (a by-product of coal).

heating a concrete shower

You can heat a concrete shower

If you want to add a sense of luxury to your bathroom, you can improve the functionality by adding a heating element. Heated concrete showers are more comfortable and appealing. It’s hard to resist the bit of luxury in your home.

So, how does a concrete bathroom work? It involves installing some radiant heat underneath the flooring. Some of the benefits of a heated concrete shower are:

  • You can set an ideal temperature
  • Easy to install
  • Heats faster than most HVAC units

But since the bathroom has fixtures and furniture, you have to be specific with the size. The biggest advantage of heated floors is that you get uniform heating. You can heat the floor and provide an ambient temperature. This is something that works well on concrete floors. Best of all, you’ll notice that your bathroom gets warmer faster than any other room in your house.

Unlike the traditional HVAC units, heating a concrete shower guarantees a reduction in energy costs. Furthermore, it takes less than an hour to heat the bathroom. Along with energy-saving, heated floors are safe, so you won’t burn your feet. And as you turn your forced-air system, it won’t be noisy. This means that there won’t be a distraction as you enjoy your shower.

Other benefits of a heated concrete shower include:

  • They are maintenance-free – once you install, you don’t have to worry about maintenance
  • Allows for customization – most heated floors come with thermostats that allow you to create the perfect temperature
  • They are space-saving – instead of installing hefty units on the shower walls, the heated flooring units will save space because they are tucked out of the way.
  • Adds value to your home

Can easily be refinished

You can refinish your concrete shower with time to remove the discolorations. Just like you’d work on your hardwood floors, you can remove the marking and staining that form over time. The first step to refinishing your concrete floor is prepping it.

You should ensure its smooth as possible

This involves working on cracks. Once the motor is fully dry, you can use sandpaper. This will help to remove any traces of dust. Next, you should clean the concrete thoroughly to eliminate any oils that may interfere with the paint.

Painting the shower floor

There are different options for painting the shower floor. Generally, the paint you choose should contain binders that work well with the floor surface or the concrete will absorb the moisture. As you do this, be sure to follow safety procedures like wearing gloves and using an anti-respirator mask to keep paint vapors at bay.

Other than making the floor look at its best, painting a concrete shower helps to minimize humidity. Also, you should keep the shower free from any scum and mineral build-up.

Other reasons why you should get a concrete shower

You can waterproof concrete showers

While concrete floors are impervious to water damage, they can develop cracks that allow water to pass through. This can be a nightmare for many homeowners, but it doesn’t have to be an overwhelming experience.

Also, if the concrete is laid on plywood underlayment, water can sip through. Still, if cement is not waterproofed, there could be issues with the moisture between the tiles. Thankfully, you can waterproof the floor to keep moisture away.

In most cases, the waterproofing material should be water-resistant. The best materials to use are copper, stainless steel, and any other membranes. If you didn’t use water-resistant substrates during the initial construction, this is something you should consider.

Easy to repair

If the shower base leaks, you can assess the situation and determine the level of repair needed. Sometimes, the repair can be minimal, just like rolling on a sealer. Likewise, if the shower base develops some cracks you can seal them. Larger cracks may require a cement patch followed by a waterproofing membrane material.

What if the shower becomes slippery? You can use a waterproof paint color. Whether you want to redecorate or fix a problem, things can get pretty easy with concrete.

Enhances your décor

Concrete is available in distinct materials, finishes, and designs. It can be used in different ways to add a special touch to your bathroom with no creative limitations. If you want to add a rustic touch, you can use concrete tiles.

Depending on the design you use, you can leave a lasting impression on your visitors. You can also go for a simple and elegant layout that adds a touch of uniqueness. Concrete tiles come with a wide selection that fulfills the creative needs of most customers.

It’s no secret a concrete shower has become stylish additions for many homes. And many benefits come with it – from durability to ease of cleaning.

It’s time you bring a wow factor in your shower.
