Heating Ventilation Air conditioning HVAC Systems
	HVAC Design Considerations KI Associates offers design solutions for energy conservation oriented air conditioning systems that are duly compliant with ASHRAE, National Building Code (NBC) 2005 and Energy Conservation Building Code (ECBC). Some of the main features requiring close attention are as follows: Sizing HVAC System We, at KI, understand that appropriate sizing of HVAC components is critical for the design of energy efficient HVAC system at optimum cost. Hence we adopt a systematic approach towards HVAC sizing, taking into consideration various factors such as climate, building configuration, space usage, system zoning and layouts.
Chilled Water Plants and Distribution KI adopts high efficiency water cooled, low IKW/TR chillers on most of the projects. Depending upon their type and capacity, large chillers are specified with variable speed drives. All the chillers are specified with microprocessor based control system along with chiller manager to monitor all the parameters of the plant. The plant generally consists of energy efficient screw chillers/centrifugal chillers/VFD driven chillers, multiple primary chilled water pumps, secondary chilled water pumps with variable frequency drives, condensing water pumps, FRP cooling towers, VFD driven double skin air handling units with thermal break and variable frequency drive, fan coil units, chilled and condensing water piping, air distribution system, insulation, electrical panels, wiring, control wiring and earthing A significant amount of energy is used to distribute water for space cooling due to year round cooling loads in most parts of India. An efficient and proper design can result in substantial operating and capital savings, and can thus have a significant impact on a building's total energy consumption. Hence, at KP, the thrust is to use variable speed pumping system, a concept pioneered in India by KP in the early nineties.

	Electrical Systems KI provides energy efficient electrical systems requiring minimum level of maintenance and providing maximum level of safety and energy saving. Internal Electrical Design We design electrical systems using the latest technologies considering specific project requirements along with compliance of all relevant Indian and International codes. We take into account fundamental principles of energy conservation and safety that encompass protection against electric shocks, thermal effects, over current, fault current and over voltage. All these potential hazards are addressed at the time of design, resulting in an installation that is essentially free from hazards, convenient in operation and adequate for a long trouble-free service. Dimmers are provided for lighting circuits to reduce the lux level at times when higher lighting level is not required. Also sensors are provided to switch off lighting when the space is not occupied or where natural light is available to achieve the required lux level. External Electrical Installation We recommend the use of astronomical time switches for controlling external lighting. These switches are programmable on the basis of sunrise and sunset, and work without the use of light sensor. Programming is done at the project site to switch the external lighting ON and OFF automatically at a preset time and also switch OFF 50% lighting at midnight or another preset time. This saves substantial amount of electricity and increases the life of lamps.

	Plumbing & Public Health Engineering Water Supply, Pumping, Piping and Distribution We ensure that the water distribution system meets optimum performance parameters and the functional requirements of the installation. Water requirement is calculated on the basis of occupancy and area served, to plan storage tanks of adequate capacity. Pumping systems are selected based upon the best efficiency on the duty curve and the quality of water being supplied. In case of piping design, fixture unit method is used in accordance to national NBC and/or international (ASPE / UPC) standards. Central Hot Water Generation and Supply Hot water generators of adequate capacity are designed based upon the hot water demand and ambient temperature of the cold water feed. Hot water generators are suitably located along with ancillaries such as plate heat exchangers, soft water plant, fuel oil supply tank, hot water mixing tank and hot water return pumping system. Water Treatment We plan the water treatment in accordance with the total quantity of water that is required to be treated, the water analysis report of raw/source water and its ultimate purpose. The domestic water qualities parameters are considered in accordance to limit prescribed by the local codes. Various options for water treatment equipment include filtration units, softener Units, dozing Units, pH Correction or RO units.


	Fire Fighting Systems We plan the fire-fighting and fire-protection systems in accordance with AHJ (Authority Having Jurisdiction) standards, and/or international standards such as NFPA or FM. Water is stored in underground fire reserve tank of the stipulated capacity, and is drawn using electrically driven jockey pumps, fire pumps or sprinkler pumps. All pumps have a separate suction line from the fire suction header. Delivery from the pumps is connected to the respective hydrant and sprinkler system, for which installation control valves with hydraulic alarm are provided in the basement. The sprinkler pump is isolated from the main discharge header by a no-return valve so that the hydrant pump can also act as standby for the sprinkler system. The pumps are designed to maintain a pressure of 3.5 Kg/Sq.cm at the farthest hydrant. A standby diesel engine driven fire pump of the same capacity is installed as back-up for the electrically operated fire hydrant/sprinkler pump, as per fire regulations. Independent jockey pumps for hydrant and sprinkler system operate intermittently in order to take care of hydraulic losses in the system and maintain the minimum pressure respectively in wet risers and sprinkler system. Fire pumps rating is in accordance with AHJ directive and also caters to future expansion requirement.
