Tanzania’s hospitality sector is expanding rapidly, driven by record tourist arrivals and
rising hotel occupancy rates. According to the Tanzania National Bureau of Statistics (NBS)
2024 International Visitors’ Exit Survey, hotel occupancy across the country reached 74.5%
in 2024 — and with international arrivals continuing to climb in 2025, demand for quality
accommodation in Dar es Salaam, Dodoma, and Mwanza is only going in one direction. Dar
es Salaam remains the commercial heart of this growth, accounting for 37.6% of Tanzania’s
total construction activity in 2025 per the Mordor Intelligence Tanzania Construction
Market Report. Dodoma, as the seat of government, presents steady demand for business
accommodation, while Mwanza’s position as gateway to the Serengeti and Lake Victoria
circuit makes it a strong target for both leisure and corporate hospitality investment.
If you are planning a hotel project in any of these cities, this article is for you — not to
discourage you from building, but to make sure the building you put up is one that
performs. The difference between a hotel that delivers strong returns and one that
struggles to break even often comes down to a single early decision: whether or not you
engaged a professional MEP engineer.
The reason is straightforward. MEP — Mechanical, Electrical, and Plumbing engineering —
governs everything in your hotel that keeps guests comfortable and the building
operational: air conditioning, power, hot water, drainage, fire detection, lifts, and
communications. In a hotel, these systems are not a minor line item. According to the
Tanzania Investment Consultant Group Ltd (TICGL), MEP services can account for up to
45% of total hotel construction costs — and HVAC alone can represent 40–60% of total
operational energy spend over the building’s lifetime. Getting these systems right from the
start is the most impactful investment a hotel developer can make.
The Air Conditioning Problem: Why Mechanical Engineers Must Size Your
System
Of all the MEP disciplines, mechanical engineering — and specifically HVAC design — is
the most consequential for hotel developers in Tanzania. Here is why.
Dar es Salaam sits on the Indian Ocean coast at approximately 6°52’S, with a hot and
humid tropical climate. Average temperatures hover between 25°C and 32°C throughout
the year, with humidity regularly exceeding 75%. Research comparing energy performance
of office buildings in Dar es Salaam confirms that the city’s hot, humid tropical climate
(Köppen-Geiger class Aw) drives year-round cooling demand, and that building
classifications and HVAC type are the most significant predictors of energy use.
Dodoma, though drier and at higher elevation, experiences extreme daytime temperatures
regularly above 35°C during the dry season. Mwanza on the shores of Lake Victoria is
warm and humid year-round, with the lake’s moderating influence still maintaining high
moisture levels that make cooling essential.
In all three cities, air conditioning is not optional in a hotel — it runs continuously.
Research on hotel energy consumption across climate zones confirms that hotels in tropical
climates use significantly more electricity than those in temperate zones, driven directly by air conditioning demand. An air conditioning system that is over-specified wastes capital
and drives up electricity bills for the life of the building. A system that is under-specified
cannot maintain comfortable temperatures, leading to guest complaints, poor reviews, and
reputational damage.
What will they do?
Only a qualified mechanical engineer can properly size your HVAC system. This involves:
Conducting a thermal load calculation. This is a room-by-room and zone-by-zone analysis
of heat gain from the sun, occupants, lighting, equipment, and external climate. It
determines the exact cooling capacity required for each space. Without this calculation,
contractors default to oversizing — which costs more to install and far more to run.
Selecting the right system type. The choice between split units, Variable Refrigerant Flow
(VRF) systems, package units, and chilled water central plant has major implications for
cost, flexibility, and efficiency. VRF systems, for example, can adjust the flow of refrigerant
to different areas of a building, providing customised cooling where needed and
minimising energy waste — making them well-suited to hotels where occupancy levels
fluctuate significantly by zone and time of day.
Specifying energy-efficient equipment. A mechanical engineer will specify inverter-driven
equipment, correct refrigerant types, and appropriate insulation standards — all of
which reduce electricity consumption over the 15–20 year life of the system.
Integrating with Building Management Systems (BMS). A professionally designed HVAC
system includes controls that automatically adjust cooling based on occupancy, time of day,
and external temperature. Smart thermostats and advanced BMS allow for precise control,
monitoring occupancy and adjusting temperatures accordingly — minimising energy
waste when rooms are unoccupied, for instance by allowing temperatures to rise slightly in
empty rooms to reduce cooling demand.
Financially Hotels that adopt energy-efficient MEP upgrades and design
strategies can reduce energy costs by 20–30% — a difference that compounds significantly
over decades of operation. For a 100-room hotel in Dar es Salaam, that saving can represent
tens of millions of Tanzanian shillings per year.
Five Reasons to Hire a Professional MEP Firm for Your Hotel Project
Avoid Costly Mistakes That Cannot Be Undone
MEP systems are embedded in the fabric of the building during construction. A poorly
designed electrical distribution system, an undersized plumbing stack, or HVAC ductwork
routed through the wrong zones cannot be easily corrected after walls are plastered and
ceilings are sealed. The cost of rectifying MEP errors post-construction is typically three to
five times higher than getting the design right from the start — and that is before
accounting for operational disruption and guest inconvenience once the hotel is open.
Reduce Your Construction Cost Through Optimised Design
A common misconception is that engaging MEP professionals adds cost to a project. The
opposite is true. An experienced MEP engineer will right-size every system, eliminating
unnecessary capital expenditure on excess capacity, and will identify value-engineering
opportunities — specifying local materials where appropriate, coordinating services to
avoid on-site clashes, and ensuring procurement is planned well enough in advance to
minimise logistics costs, particularly relevant for projects in Dodoma and Mwanza where
materials travel further.
Ensure Compliance with Tanzania Building Regulations
Tanzania’s construction regulatory framework — administered through the Tanzania
Building Agency (TBA) and the Engineers Registration Board (ERB) — requires that all
building services designs for commercial projects be prepared and signed off by registered
engineers. Non-compliant buildings face delays in obtaining Certificates of Occupancy and
are subject to mandatory rectification orders. A professional MEP firm ensures all
installations meet applicable Tanzanian standards and East African building codes, and
that documentation is in order for regulatory sign-off at every stage.
Protect Your Guests and Your Operating Licence
Fire safety is non-negotiable in a hotel. Tanzania’s regulatory framework requires
functional fire detection, alarm, and suppression systems in all commercial
accommodation, and failure to comply can result in the revocation of your operating
licence. Electrical safety is equally critical — improperly designed electrical systems are a
leading cause of hotel fires globally. A professional MEP engineer designs and specifies fire
and electrical systems with the appropriate protection devices, earthing, load balancing,
and emergency provisions to keep guests safe and your licence secure.
Attract Higher-Value Guests and Command Better Room Rates
International travellers — whether corporate guests in Dodoma, leisure tourists transiting
through Mwanza, or business visitors to Dar es Salaam — expect consistent MEP
performance as a baseline: rooms that reach temperature quickly, reliable hot water,
working lifts, and stable power and connectivity. These are not premium features; they are
the minimum standard that determines guest reviews, repeat bookings, and positioning on
international booking platforms. In a market where competition is intensifying, a well-engineered
building is a direct commercial differentiator.
