�Sustainable construction (Green Buildings) aims at

reducing the environmental impact of a building over

its entire lifetime, while optimizing its economic

viability and the comfort and safety of its occupants.

�A building designed and constructed in a sustainable

way minimizes the use of water, raw materials,

energy, land, etc. over the whole life cycle of the

building.


What is it?

Salient Features Of Green Buildings

�Effective use of soil & landscapes

�Structure design efficiency

�Efficient use of water & electricity

�Use of renewable energy

�Waste reduction

�Use of recycle/recyclable materials

�Energy efficient & eco-friendly equipments

�Operations & maintenance optimization

�Improved indoor air quality for health & comfort

52

EIFS –What Is It?

�EIFS –Exterior Insulation & Finish Systems

�D

efi

nit

ion: Exterior assembly comprising of rigid insulation,

�adhesive, base coat, reinforcing mesh and finish coat.

�Multi-layered Systems

�Useful For Commercial & Residential Buildings

�Provides Superior Energy Efficiency

�Offers Greater Design Flexibility

53

Why EIFS?

�EIFS has proven to have superior energy efficiency by

reducing heat transmission.

�Improved energy efficiency helps to reduce green-house

gases associated with energy production.

�Design flexibility and decorative

finishes.

�Superior energy efficiency reduces

HVAC equipment capacity.

�EIFS can be applied to new or existing

structures.

�EIFS is the ONLY solution for

insulating existing buildings.

54

Advantages of EIFS

�What Are The Advantages to EIFS ?

•External Location

•Virtually Seamless –Reduced Air

Infiltration

•Consistent Inside Air Temperature

•New or Renovation Capabilities

•Shapes, Colors and Textures

•Flexible and Lightweight Material

•Little Routine Maintenance

•Design Flexibility

Pervious Concrete

Pervious Concrete is -

�A zero-slump, open-graded material with

Portland cement, coarse aggregate, little or no

fine aggregate, admixtures, and water

�Pores, ranging in size from .08 to .32 in. (2 to

8mm), that allow water to pass through easily

�The void content can range from 18 to 35%,

with typical compressive strengths of 2.8 to 28

MPa

�The drainage rate of pervious concrete

pavement will vary with aggregate size and

density of the mixture,butwill generally fall

into the range of 81 to 730 L/Min/Sq.M

67

Pervious Concrete –Applications

�Parking Lots

�Streets, Road Shoulders

�Bridge Embankments

�Edge Drains

�Driveways, Sidewalks

�Patios, Tennis Courts

�Swimming Pool Decks

�Golf Cart Paths

�Greenhouse Floors

�Zoo Areas, Animal Barns
