the facility. A few buildings including railway station building are proposed to be reconstructed, few new
structures are also proposed in this project. This chapter of report is describing the basis of HVAC
design system of various proposed areas.

Geographical Details

The project location are as

shown.
Its latitude and longitude
coordinates are:
30.7028° N, 76.8193° E

1. General
This report is prepared to outline the basis for the Mechanical services which encompasses
architectural planning, engineering standards and applicable national & international codes.
The proposed Mechanical design will be appropriate for a Railway Station considering comfort,
maintenance & operating cost. The design will be proposed to meet the client, architecture & other
services requirement without compromising the engineering standards.
The design proposed in the report has been prepared based on the information furnished by the client &
architect and available standard data.

While the basic system design is not likely to change, the rating and specification of the main equipment
may change after firming up of inputs and detailed engineering.

2. Design Principle

The basic principles on which the Mechanical services design will be based are: -
 Suitability
 Feasibility
 Energy efficiency
 Simplicity of functionality to satisfy end user requirements
 Flexibility for future change and adaptive reuse
 Ease of maintenance
 System life
 Capital and running cost

Besides the above, an integrated design approach will be pursued so that the project ranks high on the
sustainability scale and the platinum green rating from Indian Green Building Council. The equipment
selection shall be optimized keeping in view full load as well as part load characteristics.

3. Ambient Design Conditions

Chandigarh weather data is followed for Hissar which is 250 km away and almost experiences same
conditions throughout the year.

It experiences all three main seasons: summer, monsoon and winter. Aside from the monsoon season,
the climate is dry. The weather is hot during April to July, when the average maximum is 45 °C. From
November to February, the temperature remains low and the climate is extremely dry. In December to
January it experiences cold weather. Monsoon occurs from mid-June to mid-September.

3.1 Design Temperatures

The ambient design conditions are selected from ISHRAE Weather Data 2017 (Refer: Section-1 &
Table 1.2, Page No. 1.5) at 0.4% occurrence with factor of safety as per past experience & temperature
rise in future which is as follows:

Weather Data
Condition/Season
DBT (˚C) WBT (˚C) RH (%)

Summer 44.6 25.6 22

Monsoon 34.1 30.1 75.2

Winter 6.72 6.66 99.3

Note: The ambient temperature may exceed above selected design temperature for approximately 35
hours (0.4%) in a year (8670hrs). This will not impact the cooling as the ambient temperature
considered includes factor of safety above the conditions at 0.4% occurance for future temperature rise.

Lift well will be pressurised through axial flow fan / SISW Centrifugal Fan to achieve 50 Pa (As Per
NBC-2016, Part-4) differential pressure across the lift well and adjoining spaces. The fan will be
installed at roof level and the air will be discharged from the top to pressurized the well. In case of
multiple lift wells, a single fan can be used of each lift well or we can also use single fan for two or
more lifts will be provided based on final space & lift arrangement.

16.6 Lift Lobby Pressurization

Pressurization shall be provided as per NFPA / NBC.
we have considered the mechanical system for the lift lobby pressurization. The lift lobby
pressurization through axial/Centrifugal cabine type fan fan to achieve 30 Pa differential pressures
across the lobby and adjoining area (As per NBC-2016, Part-4). The fan will be installed on the roof
level and the duct riser in the shaft or shaft itself with tap-off at each floor will be used to pressurize
lobbies at each level. Each tap-off will have VCD for air balancing and grill.

16.7 Staircase Pressurization

Pressurization/Natural ventilation shall be provided as per NFPA / NBC.
Staircase with the external wall will be naturally ventilated as the staircase will have the wall louvers
at each landing. Hence, we have not considered any mechanical ventilation system for the staircase
with the external wall. In case if there will no wall louvers than the Pressurization will be provided to
maintain 50 Pa between the staircase (As per NBC-2016, Part-4) & adjoining space and the same
will activate during fire and prevent smoke ingress into the escape route. This is to maintain the
required pressure throughout the staircase and to restrict the door opening force.

Staircase with no external wall will be pressurized. It will be provided to maintain 50 Pa between the
staircase & adjoining space and the same will activate during fire and prevent smoke ingress into
the escape route. Supply injection can be done at multiple levels depending upon area & location for
mounting the fan. This is to maintain the required pressure throughout the staircase and to restrict
the door opening force.

16.8 Public Areas Smoke Extraction System

For Closed Public areas, smoke extraction system shall be designed to achieve 12 air changes per
hour (ACPH) during fire mode as per National Building Code of India (NBC) 2016.
Smoke exhaust shall be suitably drawn. For make-up air motorized openable windows shall be
provided. Both fans & dampers shall open upon getting signal from the fire alarm system. Smoke
exhaust fans shall be fire rated suitable for 2hours fire rating rated at 250 deg C for 2 hours.

16.9 Track Ventilation

Platform is partly covered with the concourse slab as shown in architectural drawing. As
there are fair chances that locomotive exhaust and heat can get trapped in this area and can put
users in an uncomfortable situation (suffocation’ low visibility and heat) hence ventilation jet fans
(duct less ventilation) along the tracks are proposed to cater to the requirement.
fire rated suitable for 2hours fire rating rated at 250 deg C for 2 hours.

These fans shall operate only in case of a temperature rise and smoke detection in the affected area
only, to keep environment healthy for users in this area. For detail design CFD of this area will be
done by after finalization of vendor/contractor for analyse the exact Jet fan configuration and location
on the basis of heat and smoke behaviour.

16.10 Concourse (HVLS FAN) (As per IS/RDSO-PSE/1002:2023)

Within concourse and double height food court, HVLS fans shall be provided for air circulation.

Beacause through roof is completely open 360° up to the base & Truss & Apex is ventilated
through sectional louvers, hence mechanical ventilation system is not required.

16.11 Air Curtain

In all areas wherever comfort air-conditioning is provided air curtain of suitable width shall be
provided to stop entry of mosquitos, flies and dust etc. this shall also help in energy conservation

and maintaining indoor conditions. Such fans shall have auto start stop based on entry of person
in the area. Fans shall be low noise heavy duty.

17 Integrated Building Management System

Integrated Building Management System (IBMS) is a computer-based control system which can
handle the or monitor installed system from one point of building. We can integrate the other system
like VRV/VRF Units, ventilation Fans,

The IBMS system shall be provided to monitor and control desired parameters of MEP systems to
make the operation & control convinient. The parameters to be controlled through IBMS system will
be carefully selected according to proposed MEPF system for one point control which will be finalized
after discussing with client during detail design stage.

18 Expected Useful Life of various Mechanical Equipments/ Installations

Sl No. Description of Equipment & Installation Life in Years

A Fans
Axial Fan/Inline Fan/Propeller Fan 10 -15
Evaporative Unit (Air Washer) 5-10
B Air Conditioner
VRV AC Unit 10-15
DX Split Unit 7

Note:
These are general guidelines. Proposal for replacement will be based on actual hours of operation/
condition of use and inspection by the concerned authority. Based on adverse working conditions, it
may be necessary to replace installation earlier. Similarly replacement can be postponed if the
existing condition is found to be satisfactory based on detailed inspection done. But it is necessary to
keep close watch, when useful life is going to be over.
