Cooling fit for a mosque
Mosque HVAC in Madinat Al Sultan
In Madinat Al Sultan in south Jeddah, mosques sit in a relatively modern residential zone with tall buildings, and a modern cooling system combining efficiency and reliability is essential. Alrabih designs systems suited to contemporary architectural spaces with even cold distribution and the quiet needed for worship.

When a mosque needs a specialist approach
- 1
Heat reaching the back rows
Cold air pools near the units and never reaches the back of the hall. In Jeddah's humidity, worshippers in the far rows feel the heat even with the system running. That is a design problem, not a unit fault.
- 2
Noise that disturbs prayer
Unit noise in a quiet hall distracts worshippers and breaks concentration. The right unit type, its position and the air velocity setting all reduce noise to the lowest possible level, and those choices are made at the survey.
- 3
A dome or high ceiling that traps heat
Hot air rises and collects under the dome, so the breathing level stays warm even with large units running. We set diffuser angles and air paths at the survey to push that hot layer out rather than cool over the top of it.
Who it's for
Building a new mosque that needs AC from the start
We join the design stage to fix duct routes and unit positions before ceilings are closed, so the installation is clean and efficient with no remedial work needed later.
Ask on WhatsAppYour existing mosque cools unevenly across the rows
We survey the existing system, find the cause of uneven distribution and propose changes to the airflow paths or units without disrupting the mosque.

What the work covers
- Hall survey and airflow mapping
- Ductwork to SMACNA standard
- Units fitted at surveyed positions
- Airflow check across the rows
- Contracts scheduled between prayers
How we work
How we work
- 1
Mosque survey
We visit the mosque outside prayer times to measure the hall, ceiling height and dome, and agree diffuser positions, duct routes and unit locations before any work begins.
- 2
Design and fabrication
We design the system from the survey data and fabricate the ducts in our own workshop from G90 galvanised sheet, then prepare them for installation.
- 3
Installation at agreed times
We coordinate with mosque management to work between prayers or at times that do not interrupt activities, and we leave the hall clean at the end of each working day.
- 4
Testing and handover
We run the system and measure air distribution at the front and back rows and sound levels, adjusting the balance until comfort is even across the whole hall.
Designed for a mosque or units placed at random?
| Alrabih | The usual way | |
|---|---|---|
| Air distribution | Even across every row | Cold front, hot back |
| Sound | Assessed at survey | Not considered |
| Dome and high ceiling | Planned airflow paths | Hot layer left above |
| Maintenance | Scheduled between prayers | Visits that disrupt use |
| Startup scheduling | Programmed before each prayer | Manual, inconsistent start |

What sets this district apart
Madinat Al Sultan is a relatively modern residential neighbourhood with tall contemporary buildings and spacious mosques with good architectural designs. Temperatures run very high in summer because the zone is open and wide, and humidity is moderate because the area sits closer to the sea than central districts. Mosques here are usually larger than those in older neighbourhoods and serve dozens to hundreds of worshippers, and the buildings are relatively new, making coordination easier. Design focuses on energy efficiency to reduce electricity bills for mosque authorities, and reliable cold-air distribution across connected, open architectural spaces.

Madinat Al Sultan mosques are generally larger and feature spacious halls with moderate ceiling heights and good open spaces.
The AC setup in Madinat Al Sultan
- 1
Energy-efficient central cooling unit
Modern architectural designs allow installation of an energy-efficient central cooling unit, reducing operational costs for the mosque authority.
- 2
Ducts integrated into the architectural structure
We design ducts to integrate with the hall's architectural spaces, using contemporary open areas and hidden ceilings where available.
- 3
Smart temperature control system
We install a control system that allows temperature adjustment based on time of day and expected attendance, improving both efficiency and comfort.
Before the visit
Before our visit in Madinat Al Sultan
- 1
Obtain the complete architectural drawings
Obtain a copy of the mosque's architectural drawings, including ceilings, hidden spaces and existing runs, so we design the system precisely.
- 2
Identify external windows and openings
Identify the locations of large external windows and openings, especially glazed ones, so we account for them when sizing the cooling capacity.
- 3
Confirm roof access and outdoor unit location
Confirm safe roof access and identify a safe, suitable location for the outdoor unit that doesn't disturb neighbouring buildings.

FAQ
Questions about Mosque HVAC
How do you make sure the far rows get enough cooling?
At the survey we set diffuser angles, air velocity and duct routing so cold air travels to the last row. After installation we measure the temperature difference between the front and back rows and adjust each diffuser's balance until that difference is as small as the space allows.
Can you work in a functioning mosque without disrupting prayers?
Yes. We agree a phased schedule with mosque management in advance and divide the work into sessions between prayers. Before each call to prayer we lift tools, cover any temporary openings and return the hall to a usable state, then resume afterwards.
What type of ductwork do you use in prayer halls?
We fabricate ducts in our own workshop from G90 galvanised sheet, round or rectangular as the design requires. We use Armaflex and Kimmco insulation and Foster sealants to limit heat gain and keep sound transmission through the ductwork as low as possible.
Can the system be set to start just before each prayer time?
Yes. The controls on Carrier, YORK, General, Midea, Gree and Smart Gold units support scheduled start and stop times. At the survey we confirm the scheduling options for the chosen units and programme the timings at handover, so the hall is already cool when worshippers arrive.
Can we cool only part of the hall when fewer people attend?
Yes, if the system is designed in zones. We divide the hall into sections, each with its own unit or closable outlets, so you run the front rows alone when few people attend and the whole hall for Friday prayer and occasions, cutting power use without affecting worshippers.
Our new mosque has contemporary design; how do you design the system for such buildings?
We leverage the contemporary architectural designs and open spaces to install an effective, reliable central cooling system. We work with the architects before finishing to ensure complete compatibility.
The area is very hot and electricity matters; how do you balance power with efficiency?
We select energy-efficient cooling units with capacity sufficient for extreme heat, reducing the electricity bill without compromising performance. We recommend regular maintenance to preserve high efficiency.
The mosque has large glass facades; does that increase the cooling load?
Yes, large glass increases the heat entering the hall from sunlight, which we account for when sizing the system and recommend thermal curtains to reduce heat gain.
The ceiling height is moderate; does that help with cold-air distribution?
Yes, moderate ceiling height helps reliable cold-air distribution without strong draughts, and reduces the required capacity compared to very high-ceilinged halls.
