How Crucial is Interior Design for Supermarkets?

Shopping for groceries may constitute retail therapy sometimes, for some people, but generally, it’s a chore. It’s a chore that involves spending valuable time at supermarkets that know how to work on human psychology to induce people to buy items they don’t really need. Interior design in supermarkets is geared towards optimising this social reality. Retailers understand that the layout of supermarkets and the placement of different items can impact consumer spending considerably. For store design & planning team, outsourcing technical services, such as architectural CAD drafting services and BIM consulting services to offshore partners has proven to be an efficient and cost-effective solution to developing supermarket interior design that can set the supermarket’s tone and increase profits.


The designing of a supermarket’s layout requires insight into basic human psychology. Designers spend time and effort to create a supermarket layout that will influence customer spending. The flow, merchandise placement and ambience of the store layout will affect the behaviour of customers. Retailers can assess their proposed revenue by looking at these layouts, resulting in informed decisions regarding the pros and cons of their mix of merchandise and where to place them. 

Some of the proven features of customer behaviour and how they can be used to determine layout plans are as follows: 

  • Longer stay in a store results in a higher chance that something will be bought. So, retailers try to delay the customer’s exit.
  • Store traffic will be affected by the placement of escalators, fixtures and department placement.
  • Necessities, such as milk and eggs, are frequently located in the back of the supermarket, so that customers must pass the maximum number of other merchandises to get to them, thus potentially enticing an impulse buy. 

Other interior design features retailers use to provoke additional sales include the following: 

  • Grouping

Merchandise is grouped in categories, so that when customers are looking to buy a specific product, they will discover other related products, which they may or may not require. Salsa and chips, breads and sandwich spreads and detergents and rubber gloves are placed adjacent to each other.

This also involves placing similar brands close together to ensure that customers who are loyal to a brand are able to find the one they want, resulting in additional cross-category or cross-brand sales. 

  • Layouts for Theft Prevention

Displays or sections with small items that can be easily stolen are typically placed near security support, such as near the exit, before the check-out counter – somewhere that has extra security personnel or that involves a barrier for an extra physical movement, so that it is not easy to flee from the premises. 

  • Displays that Encourage Positive Vibes

When customers are feeling good and comfortable, they feel good about their purchases. Layout design can set the mood through merchandise placement, aisle space and colours of fixtures and walls. 

  • Shelf Height

Fixtures that are so tall that they block visibility has been known to cause anxiety, since shoppers must travel through every aisle. When the layout is open, anxiety is reduced, inducing shoppers to linger and make more purchases.

Why is shelf positioning so important to retail interior design?

Supermarket sales are dictated by positioning, the importance of which determines ‘shelf rent’ (cost of certain shelf positions for each product) in many cases. This is because customers need to easily view a product to buy it. A product which is hidden behind other products or on lower/higher shelves than the range of space that is easy on the eye may not sell as much.

Factors that influence where products sit on the shelf include the following: 

  • Increasing Profits

A product’s ‘selling’ potential influences its shelf position. Eye-level on a shelf is considered prime real estate in a supermarket.  High-demand items, such as food staples, with high sales potential will be placed at eye level to ensure that as many units as possible are sold. Branded products are often placed on lower shelves to make way for in-store brands and special offers on eye-level shelves. 

  • Targeting Customers

Understanding the target customers of different products is important. The maximum focus is on products at eye level, but some target consumers are of a different height. Children will notice, crave and insist on buying products at their eye and hand level, which means that toys, stuffed animals, most junk food and fizzy drinks may sell better from lower shelves. Products that appeal to adults will find space on higher shelves.

The supermarket has slowly evolved into the market square of old. Open plans, open ceilings and clear store graphics contribute to an open market feel.

How does a supermarket’s floor layout affect sales? 

  • When customers are directed by a layout plan to walk to the back of the supermarket, they will inevitably see many other items on the way. At some point on their walk, they will be enticed to pick up certain products they had not planned for or were not aware of, increasing sales for the supermarket.
  • Clever supermarket owners will consciously position high-volume products, such as milk and bread, at opposite sides of the supermarket floor, so as to maximise the consumer’s exposure to merchandise placed between them. In-store bakeries will be placed in a central position, since the aroma of freshly baked items will encourage impulse buying by hungry customers.
  • Putting fresh produce, such as fruits and vegetables, near entrances gives rise to a few simple benefits. During the day, the natural light that falls on fruits and vegetables makes them look better and naturally fresh. As they are seen first, this produce will be picked up quickly and by a larger percentage of visitors, ensuring that most of such perishable items are not left behind. Since supermarket owners are cognisant of how people want healthy food, a spacious produce area will encourage customers to linger and spend more on fruits and vegetables. 
  • Flowers also brighten up and beautify the entrance. Seeing something beautiful and smelling the floral aromas enhances the feeling of freshness. Placing them close to the fruit and vegetable section increases the freshness quotient of both.  
  • Cooking ingredients and canned goods along with other general merchandise are usually placed in the central aisles to lure customers deeper inside the supermarket, so that they are exposed to nonessential goods while getting there. 
  • Eggs, meat and dairy products are ideally lined up on the back wall of the supermarket space to make sure people see a variety of products that may facilitate ‘impulse buys’. Traditional ‘impulse buys’, such as magazines, mints and chocolate bars are placed at the checkout counter, which makes waiting in line a perfect opportunity for that ‘final sell’. 
  • Sampling stations, special live display counters and cooking demonstrations typically line one of the outside walls to slow customers down while they are exposed to other products.

Increasingly, supermarkets are contributing to initiating and sustaining social connections. Parisian supermarkets are introducing areas where patrons can enjoy wine and warm food with friends. American supermarkets are trying to incorporate sections where customers can sip cocktails. Delicatessens and cafés should ideally be located at one of the front corners, so that people have the option of eating first, relaxing and then shopping, making it more likely that they will buy more items.

Enabling the development of 3D design in décor manufacturing, lighting and interior design involves the use of 3D modelling software, lighting test labs and a design resource library. Lighting tests can help predict the effects of bright, fluorescent lights or soft mood lighting on triggering a need to buy in customers. Such 3D previews help visualise the supermarket and its effect on the shoppers inside.

Many firms in Western countries are moving towards outsourcing architectural drafting services, including the delivery of retail construction drawings. High-quality retail design drawings and architectural BIM services can help develop designs with detailed dimensional accuracy, that can be digitised and modelled, so that revisions and changes can be made quickly and easily. Offshore companies provide architectural CAD drafting services that are precise, cost-effective and that enable the 3D visualisation of a supermarket space, plan, layout or strategy, which ultimately helps supermarkets increase their profits.

Why CFD Is a Key Factor for Fire Protection Design

Fires are scary, a chemical reaction that can strangely assume lifelike qualities and can easily get out of control. Wouldn’t it be nice if there was some way to predict or calculate potential high-risk areas in building spaces where fires may start and how they would spread? Computational fluid dynamics (CFD) is an analytical tool to calculate fluid flows, with or without solid interaction. It is vital that fire design service providers use CFD and CAD modelling services to help design an effective fire protection system.

Understanding how CFD analysis works may seem a little bit like a physics lesson, but it’s actually worth considering.



Fluids flow according to their physical properties, such as pressure, velocity, temperature, density and viscosity. This is what happens in a CFD analysis in simple terms: 

  • To analyse fluid flow, a model of the physical case and a numerical method is created digitally.
  • The model can vary according to changes in the values of heat transfer, mass transfer, phase change, chemical reaction, etc.
  • Depending on the software (typically Autodesk CFD, AnsysCFD, OpenFOAM, etc.), the amount of physical prototypes can be reduced and a product development process can be generated for fire protection design.

What does fire protection design for a building entail? 

Buildings may have different fire protection needs, eg, the fire protection needs for warehouses or storage facilities differ from those of office buildings. The design for any building involves an integrated approach, such as follows: 

  • System designers analyse building components.
  • Building function, occupancy, installed systems and footprint are considered.
  • Building owners, management, architects, engineers, consultants and contractors and their input are inherent in the design process and design data.
  • Fire protection design must adhere to the fire codes of the concerned region.

The main goals of fire protection systems are: 

  • To save lives
  • To save property
  • To preserve business continuity

How does it fulfil those goals? The basic strategy for fire protection systems involve: 

  • Detection
  • Alarms and notification
  • Suppression

Fire protection engineers can design systems to detect, contain, control or extinguish a fire, in its early stages, as follows: 

Detection Systems

  • Smoke detectors sense smoke and trigger alarms.
  • Smart detectors can sense different alarm thresholds.
  • Heat detectors can trigger alarms before smoke detectors.

Alarms and Notification Systems

  • Two types of alarms – 1. To alert building occupants, 2. To alert emergency responders
  • Fire alarms can direct fire responders to where the alarm is. Through AutoCAD floor plan integration, an AutoCAD screen with building management or building security can show which floor the alarm was activated on and can print a floor plan of that spot, which is then handed to emergency responders.
  • Speakers provide alerts in addition to bell alarms, instructing occupants where to go or whether to stay in their space.
  • Alert systems may be designed to close designated doors, turn off elevators and interface with suppression systems, such as sprinklers.
  • Alert systems may connect to ventilation components, smoke-management systems or stairwell pressure systems.

Suppression Systems

  • Sprinklers, which can reduce the chances of death and property loss due to fire by 50-65 percent compared to occupied spaces without sprinklers
  • Sprinkler heads activated individually by fire, each one with a heat-sensitive element within which activates the sprinkler head during high temperatures
  • Gaseous or chemical suppression used where water may damage equipment

With all these systems in place, how does CFD help?

The CFD software works by creating a separate model, although a replica, of the original project, created from building plans, that can graphically and numerically represent and follow the spread of fire, including its heat and smoke. Then, this data is used to create a fire strategy that is efficient, integrates the fire detection, alarms and suppression systems and follows the fire safety regulations of the region.

As CFD calculates fluid flows, using mathematical formulae and analysis, it can be successfully applied in HVAC, hydraulic systems and water systems. A 3D model is created, from CFD data and the data from building plans, with an imaginary fire inside. The building and the fire inside it are separated, or broken down, into extremely small blocks (running into millions) or simple shapes where the mathematical formulae used in CFD can be applied on individual blocks and combinations of blocks.

One of the several results of the calculations that are part of CFD is that it can help create a fire suppression model, which works something like this: 

  • The ratio between fluid mixing time scale and the flame chemical time scale is used to create a suppression model. 
  • When the fluid mixing time scale is short compared to the chemical time scale for combustion, the fire can be extinguished.
  • Suppressants are introduced to increase the chemical time required for combustion.
  • The effectiveness of suppression models in stressed and obstructed flows are analysed by using validation data.
  • CFD analyses how changes in geometry can change the distribution of suppression.
  • Design can determine the most ideal fire protection with minimal suppressant system mass and cost.

Other benefits of using CFD include the following: 

  • Cloud-based CFD simulation can help optimise HVAC systems for fire safety and smoke management.
  • CFD simulations can monitor CO levels under normal conditions.
  • CFD simulation results can help plot the magnitude, velocity and direction of air flows, helping to predict how fires can spread from any given space.
  • CFD simulations can help decide how to lower CO concentration levels in enclosed spaces, such as underground parking lots. This can help plan where to place jet fans to generate air flow. The CFD simulation can be run again with the fans to plot the new air flow velocity and check the effect on CO concentration levels.
  • CFD simulations can calculate the quantities of required supply and exhaust air to provide a smoke control system that is code compliant.
  • CFD modelling helps design public spaces with easy and safe egress, in case of fire or other emergencies.
  • CFD simulations can show the effects of sprinklers on fires.

Computational fluid dynamics makes predictive models of fire protection applications more accurate, making it a key factor in fire protection design. The capacity and means of egress have requirements imposed by building codes, which can be accurately calculated using CFD. The CFD simulations can also help fire design service providers view the performance of smoke management and general visibility in case of fire. These providers depend on the high quality and accuracy of their CAD modelling services and 2D CAD services, which is increasingly being sourced from offshore firms with CFD project experience.
