Natural Fresh Air Ventilation in Building with Ozone
The significance of the combined mechanical-electrical components of a
can be deduced from the fact that the cost of installing the equipment is
normally about one-third to two-third of the total cost of the building. In case of Hospitals, it is almost equal. The operation and maintenance costs are also more than the combined expenses for all other parts of the building. Furthermore, their expected life may be only one-half or even one third that of the buildings.
As per WHO directives the primary objective of the designer of the system, therefore, is to bring down the initial cost and evolve a design that has a reasonable maintenance cost.
This can be done by providing the simplest mechanical devices possible while
using high-quality materials; thus, the number of repairs will be reduced as will
costs for labour, fuel and power. It will also ensure that. the maintenance is within
the capability of local resources. The design should also include adequate
protection of the health and safety of staff, public and patients.

Vertical Transportation (Lifts or Elevators)
An elevator is a transport device used to move goods or people vertically. In English spoken in British and other Commonwealth countries like India, Australia etc elevators are known more commonly as lifts, although the word elevator is familiar from American movies and television.
According to the ASME A17.1, Elevator Safety Code, the definition of an elevator is "a hoisting and lowering mechanism equipped with a car or platform which moves in guide rails and serves two or more landings.
Based on elevator hoist mechanisms technology modern elevator can be classified as :
Traction elevators
Geared Type
Gearless Type
Hydraulic type
Based on Travel Type
Climbing elevator
Stair Elevator
Paternoster
Sky Elevators
Based on type of service
Passenger Elevator
Scenic Elevator
Passenger cum Freight Elevator
Hospital Bed type Elevator
Freight (Goods)Elevator
Dumb Waiter (Service lift)
Platform Lifts
Today, all new elevators are computer-controlled and microprocessor based. This allows the elevator system to place cabs where they are most needed in the interest of smooth running, with behavior based on analysis of building use called "Traffic Studies."
In most of the cases lifts are selected without any traffic analysis. Traffic Studies are done by our professional elevator consultant who use specialized tools to determine the optimum size, speed and number of elevators for a building based on its peak use periods. Computer control also permits greater control of access to various floors of a building after hours and on weekends. Methods of access control include card readers, keys, and access codes entered into the control panel of the elevator.
Access for Physically Impaired Persons: Platform Lifts
The Disability Discrimination act, (DDA) makes it a legal requirement for public buildings to provide independent access for the disabled. Elevators Ltd can help with all aspects of platform lifts
Platform lifts from Elevators Ltd, are designed to require a minimal amount of alteration to existing buildings. It is important to ensure that the correct type of lift is specified and the appropriate standards and legislation are adhered to.
Interface for Lifts
As per NBC 2005-Part 8 Building Services : Section 5 Installation of lifts and escalators page 33 following IBMS interface is needed )
1.1 Where more than three lifts are provided in a building and especially when these are provided at different locations in the building a form of central monitoring may be provided. Such central monitoring may be through a Building Management Systems, if provided in the building or through a display panel.
1.2 The following signals should be given to the building management interface from each lift.
a) Alarm button in car,
b) Door Zone or floor level information,
c) Lift moving information,
d) Power on information, and
e) Lift position information.
1.3 Each of these signals shall be provided through a potential free contact located in the lift machine room. The contacts shall be rated for 230 V ac/1 A or 24 V dc/1A. A pair of wires should be used for each potential contact.
1.4 The wiring between lift machine room to Building Management Systems shall be planned and carried out by the builder along with other wiring in the building.
1.5 The building management system should ensure that any position information is read only when the lift is not moving (lift moving information) or is capable of reading several times to detect a stable state.
In addition to the signals above the following signals may be added if required for the benefi of monitoring the lift performance.
a) A summary fault output to indicate a lift in fault condition, which prevents the lift from providing shall include the most common faults such as safety circuit open.
b) Service or inspection mode.
c) Attendant mode.
d) Fire mode.
e) Door opening.
f) Doors closing.
g) Lift moving up.
(In combination with lift moving and lift moving up information, lift moving down information can be sensed by the Building Management Systems).
h) Door Reopen Request (Summary of Door Open, Light Curtain, Photocell, Safety Edge Signals).
1.6 Where it is desired that it should be possible to control the lift from Building Management Systems, the following control signals can be provided.
a) Normal to service/inspection mode change over
b) Fault Accept/Rest Input
(Using the input, the lift controller may be allowed to clear an existing fault if this is other wise safe. It will be decided by the Lift manufacturers as to what faults can be cleared).
c) Car call to top most floor and bottom most floor of each lift.
Where such control inputs are provided, it should be with a password and login feature that allows one to determine who has used these inputs and at what time. Always such inputs should be through authorized person only. The Building Management Systems should make all changeovers effective only when lift is not moving.
1.7 Control inputs from Building Management Systems should be through a potential free contact capable of carrying 24 V dc/1 A or 230 V ac/1 A. The wiring should be terminated in each lift machine room.
Firefighting Lifts
Firefighting lifts are often single lifts situated around the floor plate. Their size is often the lowest possible permitted (8 passenger 544 Kg in India as NBC 2005,630 kg in USA), and their speed is often the lowest possible to reach the highest floor served in 60 s (1 m/s as per NBC 2005). The handling capacity is therefore low and as usually only a single lift is present at each location, the interval is equal to the round trip time. Firefighting lifts should not generally be considered as part of the vertical transportation provision, but they do provide a useful addition to the vertical transportation services of a building. For instance in a building with a large floor plate, occupants may be much nearer to a firefighting lift than the main group and may use it in preference, despite its poorer performance.
Lifts in Sky-scrappers
As a general rule, about 60 floors can be served from a main terminal lobby at ground level, by up to four groups of lifts (a practical limit). If double deck lifts are used, this permits up to 80 floors to be served from a main terminal lobby. Buildings with more than 80 floors require sky lobbies with shuttle lifts to serve them. This permits buildings of 120/160 floors with one sky lobby and buildings of 180/240 floors with two sky lobbies with single/double deck lifts. Remember the maximum practical number of lifts that can be grouped together is eight cars with four facing four.

Natural Ventilation
Natural ventilation complying with the design guidelines provided for natural ventilation in the National Building Code of India 2005 Part 8, 5.4.3 and 5.7.1.1.
Impulse Ventilation
An impulse ventilation is a system intended for the ventilation of enclosed and basement car parks without the use of ducting within the body of the car park. It may also be used in loading bays, service roads and coach parks, although these are likely to be designed against slightly different criteria.
Impulse ventilation differs from the conventional ducted ventilation system in three principle ways:
1. Ducting is not used. Impulse fans take the place of ducting in providing control of the airflow within the car park
2. Smoke management and control, which is not usually possible with a ducted system, is a key feature of the Impulse system
3. In larger car parks the system is designed for smoke control with the airflow based on a design fire size rather than simply using the air change rates which are referred to in the current Building Regulations
The system is developed from tunnel ventilation techniques and, therefore, is based on sound ventilation principles.
