All new construction projects with built up re more th n 2500 m2 (excluding p rking, b sement re , nd typic l buildings) re eligible for certi ic tion under GRIHA v.2019.

Over time, with our growing technologic l skills, these buildings h ve lso been incre singly designed nd oper ted to pl ce exorbit nt dem nds on n tur l resources, such s l nd, w ter, nd energy, to mention few. Therefore, incorpor tion of sust in ble pr ctices in building design nd oper tion is no longer choice but necessity for sust in ble future.

GRIHA v ri nts include GRIHA for Existing Buildings (EB), GRIHA for L rge Developments (LD) nd SVAGRIHA.

For good natural ventilation, building openings should be in opposite pressure zone ( since natural ventilation rely on pressure to move fresh air through buildings) The building can be oriented 0° to 30° with respect to the prevailing wind direction (wind rose diagram) / most preferably orientating longer facades of the building towards predominant wind direction Maximum air movement is achieved by keeping the sill height at 85% of the critical height. Windows should be staggered rather than aligne If the space has only one façade exposed to the exterior, it is preferred to provide at least 2 windows on the façade.

Total area of openings should be a minimum of 30% of oor area

100% percent LED lighting Site Level Planning to maximise DAYLIGHTING LOUVRES DESIGN to minimise Heat Gain but still provide ample daylighting.

MUTUAL SHADING helps in the reduction of energy consumption regarding cooling.

This is achieved through both the MASSING and the FLOOR LAYOUTS the way they are recessed and projected.

Floor Level Layout designed to maximise VIEW INTO THE LAKE VERTICAL TAPERING of the massing in the East and West Side, so that there is minimum incidence of direct sunlight thereby decreasing heat gain.

93 DEGREE NORTH turn in the orientation of the tower component to help maximise daylighting and minimise solar heat gain, while at the same time preserving the view into the DURGAM CHERUVU LAKE

TCF, Detroit

R inw ter M n gement He t Isl nd Reduction Light Pollution Reduction Site M n gement

TCF Center has various roof types including a HIGHLY REFLECTIVE WHITE ROOF, re lective pavement selections and the GREEN ROOF. Also contributing to this LEED credit were the PARKING SPACES that take up no additional physical footprint.

The ROOFTOP AND UNDERGROUND PARKING helped earn this credit by removing a signi icant amount of square footage from the roof area.

TCF Center is home to a 10,000 SQUARE FOOT living green roof that creates a natural habitat for birds and insects as well as providing insulation to cool and heat the building. It is completely covered with living green roof vegetation and growing medium, planted over a water proo ing membrane and irrigation systems alongside four honey bee hives and an organic herb garden.

The addition of HYDROPONIC GARDENS reinforces the commitment to locally sourced, wholesome foods by eliminating pesticides and fungicides while optimizing nutritional value. The program will also ensure yearround availability of fresh produce through the Midwest winter season.

TCF Center partners with Bees in the D to foster four honey bee hives on the center’s living green roof. The HONEY is used by the TCF Center culinary team and presented as gifts throughout the year during educational events on sustainability hosted by the TCF Green Committee such as tours, receptions and community outreach events.

Best practices policies address water quality and conservation methods throughout the facility including chemical management landscaping irrigation building infrastructure (toilets, sinks, urinals, and showers) e iciencies Run-o water TCF Center uses run-o water on landscaping irrigation. The savings from using run-o water is nearly 30,00,000 GALLONS annually or 30% of total usage.

Water usage reduction TCF Center continues to renovate existing restroom facilities to transition all ixtures to LOW FLOW conservation-friendly faucets, urinals and toilets.

The water ixture updates also included installation of restrictors in the sinks and water pressure is reset based on the BUILDING’S OCCUPANCY. RIVER WATER is used instead of potable water to cool condensers on chiller plants.

Condensate reclaim system TCF Center has a condensate water reclamation system that uses DETROIT RIVER water instead of potable water to cool condensers on chiller plants.

Proximity to the river permits the success of this program. The system reclaimed 5,278,862 Btu/ hr of heat energy and saved $129,242 in energy costs in 2019 .

Water bottle re ill station A WATER BOTTLE REFILLING station was placed in one of the busiest parts of the facility and tested for e icacy of use. The station was wildly popular and in 2019, TCF Center installed several more stations throughout the venue to reduce the use of water bottled with SINGLE USE PLASTIC.

ITC Kohenur, Hyderabad

Conservation processes, from planting NATIVE SPECIES to harvesting rainwater to irrigating innovatively, all combat water demand, run-o , and wastage in that order.

WATER BOTTLED in the site reduces carbon footprint reducing SINGLE USE PLASTIC Further, shading of ground covers by trees helps reduce EVAPORATION LOSSES thus reducing water consumption 100% MANAGEMENT of all the water in the building and site.

Treated water is recycled into the building for HORTICULTURE, COOLING TOWERS and TOILET FLUSHING.

Air conditioning TCF Center is air conditioned by pumping GREY WATER FROM THE DETROIT RIVER through chillers that then send the cool water to various air handlers, providing cooling to zoned areas in the building.

Energy e iciency Induction lighting is installed in the exhibit halls saving 40%t on electric use in 723,000 SQUARE FEET of space.

Computer scheduling and monitoring of lighting in the exhibit halls make sure that appropriate lighting levels are used according to OCCUPANCY. OCCUPANCY SENSORS in all meeting rooms turn o lights when not in use. Escalators are energy e icient and run based on occupancy and event needs and turned o when not in use.

DAYLIGHT HARVESTING uses outdoor light meters to automatically adjust light based on daylight coming into the building. On sunny days lighting is reduced in parking lots, interior areas like the concourse, docks and exterior lit areas.

Daylight harvesting reduces electric use by more than 10% annually. The glass-enclosed concourse area on the main level, the three story glass atrium and the third- loor corridor ceiling provide enough natural light during the daytime hours to minimize the main hallway daytime lighting.

ENERGY DASHBOARDS for Energy in TCF Center is monitored by a building automation system. This computer-based system connects the HVAC and lighting systems, enabling them to communicate on a single platform.

Vigilant monitoring of energy use daily ensures that systems are operating at MAXIMUM EFFICIENCY. TCF Center is fully automated with lighting levels and HVAC delivery speci ically scheduled to coincide with event hours

Since generation of waste cannot be completely eliminated due to limitations in processes or technology, the hotel is mandated to ensure RECYCLING OF ENTIRE (100%) WASTE GENERATED. This not only CONSERVES precious natural resources and energy but also prevents waste from reaching land ills, with all its attendant problems like health hazards, increase in GHG emissions, soil and ground water contamination, etc.
