38 Intention is to reduce ozone depletion

CFC Reduction in HVAC&R Equipment

•Commitment Employ 100% zero ODP insulation; HCFC / and CFC free HVAC and refrigeration equipments and/ halon-free fire suppression and fire extinguishing systems.

39 Optimize Energy Performance

40

•Intention is to achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impacts .

41

42 Renewable Energy (2.5%1p, 7.5%-2p,12.5%-3p)

Encourage renewable technologies to reduce environmental impacts associated with fossil fuel energy use.

•Climate respo-nsive design.

•Avoid over designing of lighting & HVAC •10%-40% less energy consum-ption through simulation •Renewable energy utilization

49 50 51 52 53 54 55 56 57 LEED recognizes that on an average people spend 90% of their time at home as a result of which IEQ becomes a very critical factor for maintaining occupants health.

GRIHA doesn’t have a category dedicated to IEQ st but the 1 two categories have subheads- Health and Well Being.

Minimun IAQ Performance

• Aims to establish minimum IAQ performance to prevent development of IAQ related problems.

Not considered

Environmental Tobacco Smoke (ETS) Control

• Aims to minimize exposure of occupants, indoor surfaces and air distribution systems to ETS. • Achieved by prohibiting smoking in the building + distancing smoking areas from others. + separating ventilation systems of smoking rooms entirely. + sealing gaps in floors, walls, etc. + weatherstripping doors

Aims to achieve zero exposure to tobacco smoke for nonsmokers and exclusive ventilation for smoking rooms

Outdoor air Delivery Monitoring

• Achieved by installing CO2 monitoring systems that generate alarm when conditions vary by 10% from set point. • Monitoring devices to be located between a height 3’ and 6’ from the floor. • CO2 and airflow measurement equipment may also be installed and connected to HVAC and BAS system for corrective action.

Not considered

Increased Ventilation

• Achieved by improving IAQ 30% above ASHRAE 62.12004 requirements for mechanically ventilated systems. Heat recovery may be adopted. • Achieved in naturally ventilated buildings by conforming to the recommendations set forth in Carbon Trust “Good Practice Guide”.

D

E During Construction • Achieved by meeting recommendations set in Design Approaches of the SMACNA IAQ Guidelines + protecting absorptive materials on site from moisture damage. • Using filtration media with a MERV of 8 at each return grill in case air handlers are used. After Construction • Using filtration media with a MERV of 8 flush out building post construction and replace with MERV 13 or better.

F

G

Aims to reduce air pollution due to on–site construction by ensuring proper screening, covering stockpiles, covering bricks and loads of dusty materials, wheel-washing facility, and water spraying to reduce respiratory problems.

63 Low Emitting Materials

Adhesive and sealants Paints Carpet Composite wood and agrifiber products Healthy indoor environment maintained by use of low VOC materials.

Indoor Chemical & Pollutant Source Control

• Achieved by employing permanent entryway systems in the direction of travel for at least6’. • Exhausting rooms with harmful gases present with negative pressure w.r.t adjacent rooms. • Providing air filtration media of MERV 13 or better.

Aims to select materials with low to zero quantities of such chemicals so as to minimize the source of emission. In selecting low VOC materials, a practical thumb rule is to choose water-based products with low odour.

64 Halon-free fire suppression and fire extinguishing systems to eliminate or control the release of ozonedepleting substances into the atmosphere.

65 Controllability of Systems Lighting

• Achieved by providing individual control for 90% of the building occupants.

Not considered

66 Thermal Comfort

• Achieved by providing individual comfort control for 50% of the building occupants.

Daylight

Achieved by providing a minimum Daylight Facto of 2% in 75% of all spaces.
