LEED A prescription for Sustainable Design

The LEED Rating System recognizes the unique nature of healthcare facilities while maintaining close alignment to LEED for New Construction.

3

Global Engineering Systems understands that healthcare facilities have unique needs:

•Strict regulatory requirements•24/7 operations•Specific programmatic demands •Energy and water use intensity•Chemical use•Infection control requirements•Heightened need for patient privacy •Health Safety Environment

Many healthcare facilities are already designed to be long-lasting, durable buildings, a core principle of sustainable design.

Brief

– Natural ventilation & passive cooling– Heat recovery systems in Air conditioning– BMS system to maximize energy performance– High efficiency heating & cooling equipment– Central lighting control system– High efficiency switch gears, lights, appliances &

fixtures– Light pollution minimized by proper illumination– Designed to measure water & energy performance– Insulated wall & doubly glazed windows– Temperature/Humidity monitoring system for

automatically adjust building conditions and linked to Building automation system

• Airconditioning – main equipment• Airconditioning – auxiliaries (pumps)• Auxiliaries –AHUs, FAHUs • Building Management System• Electrical and Lighting• Hot water generation • Medical equipment systems

Energy & AtmosphereMain Energy utility systems in the project

12

Airconditioning – main equipment– The design features of the chillers, which

account for upto 55 % of the total power consumption, already exceed the ASHRAE (American Society for Heating, Refrigerating and air conditioning Engineers) standards of baseline power consumption

– The chillers are fitted with variable speed control- one of the most energy-efficient ways of operating chillers at the highest efficiency at all capacity utilisation

– The chillers selected are of the most modern, energy-efficient one, and is being nowadays sought after by many customers who are going in for Green Building Certification

– Variable speed control helps the power consumption at all operating loads-especially when there is partial load and is expected to save about 25 % over conventional chillers

Energy & Atmosphere

13

Energy & AtmosphereHow the chillers of Zulekha Hospital Project

compare

• *Inference on the above comparison:– Chillers installed for this project save a minimum of 25 %

of conventional chillers

* Source: website of York chillers

14

Airconditioning – auxiliaries– Chilled water system with pumps

controlled with variable speed to save on pumping energy

– All AHUs (air handling units), which together account for upto 10 % of the total power, are also with variable speed controls, enabling optimum energy consumption at all running times

– FAHU (fresh air handling unit) is with heat recovery unit, thus utilising the cooling energy of the exhaust air. This design is also exceeding the recommendations of ASHRAE standards

Energy & Atmosphere

15

Airconditioning – AHUs & FAHU’s– AHUs in OTs and ICUs have double

cooling arrangement, i.e provided with units using chilled water coils normal airconditioning units, so that during chiller trippings, the normal units can continue with power supplied by the generator. This will ensure continuous availability of air conditioning even when there is power trippings

Energy & Atmosphere

16

BMS (Building Management System)– Chillers, pumps and the other auxiliaries are to

be controlled with BMS, thus enabling through automatic operation, thus operation exactly to the requirements, making the operation more-energy efficient

– BMS will also ensure that the main and auxiliary equipment all operate a optimum conditions

always, thus making the process energy-efficient – BMS also facilitates lesser dependence on manpower

Energy & AtmosphereEnergy & Atmosphere

17

Electrical & Lighting system – Generator and UPS power supply systems-power supply for the

most critical areas such as Radiology, Labs, OTs, ICUs, etc. are provided with uninterrupted power supply and generator supply backup
