INTEGRATED GREEN DESIGN GREEN BUILDING INTEGRATED GREEN DESIGN

Why Green? Green Construction !!! A structure and process that is environmentally responsible and resource efficient : from design, construction, operation and demolition. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Minimize the negative impact on environment. Reduce the Carbon Footprint. Self-sustained, eco-friendly structure Increasing energy use for other utilities like transportation due to sprawling cities & towns.

Climatic Zones Climate data : Decides in design, construction, and operation of the built environment. Guides for selection of systems for heating, ventilation and air conditioning (HVAC), tree and plant species and building material. Currently Climate related decision are made on historic climate data, past trends and current trends. North and south exposure (hot west-facing slopes avoided) 2. Deciduous trees on east and west for sun protection 3. Long, narrow shape; long walls and most glass facing north and south so smallest area faces east and west sun 4. Large overhangs and covered porches on east and west for sun protection (skylights and sunrooms avoided) 5. Operable windows placed for good cross ventilation and heat exhaust 6. High ceilings, so hotter air rises above occupants 7. Light exterior colors to reflect sun’s heat Southern exposure for best sun control (hot west-facing slopes avoided) 2. Evergreen trees on the north side to protect from winter wind 3. Masonry materials which change temperature slowly 4. Courtyard with fountain or pool for cooling effect 5. Overhangs or thick walls to protect windows from sun 6. Windows placed for good cross ventilation 7. Light exterior colours to reflect sun’s heat 1. South side of slope to get warmth of winter sun 2. Evergreen trees on north/northwest to protect from winter wind 3. Compact shape for less exterior surface area to lose heat 4. Most windows on south for sun’s warmth, fewest on north 5. Sunroom for solar heating 6. Roof slope to deflect winter winds

Integrative Design Approach The Definition The conventional definition: team members from all areas working together through a project’s development and progression. With all members on the same page from day one, lower costs as well as higher efficiencies can be achieved. The enhanced definition : About what various team members are working around: climate, building design, use, and systems and analysis by all team members to find synergies and similarities between them. Developed early 1990’s by Canada’s C-2000 program to describe a more holistic approach to building design. Aims on working together towards one goal and focuses on achieving maximum efficiency, lower costs, and increase overall performance. Sustainable Cost Effective Self Sufficient Productive Accessible Historic Aesthetics Functional High Performance Green Building

Planning & Design Stages Sustainable Site Planning Site Selection ( Opting a site with facilities easily available and causing less damage to the environment ). Building Orientation ( Improving Day Lighting and shading ) Planform ( Reduced Perimeter to Area ration for hot and dry climate and increased ratio for including water bodies and vegetation. ) Activity zoning for various planforms.

Planning & Design Stages Appropriate Landscaping Materials Less trees on the north to let in daylight Trees close to building on the west and closely spaced for sharing Trees prevent infiltration of dust laden hot summer winds Trees acts as noise and dust barrier Reducing urban heat island effect to cool buildings and surroundings Minimum environmental damage during extraction stones from sustainable mines, reuse of mine waste, wood etc. No harmful effluents into environment in installation and usage of low voc paints and cfc’s. Local materials and employment to reduce transportations energy Durability and longevity Response of material to climate in creating comfort

Planning & Design Stages Building Energy & water use Building orientations must be such that it is not heated much. Minimize carriage of heat through building skin Reduce internal heat gain and improve daylight Cooling the building through passive cooling strategies and low HVAC technologies Renewable energy for electric generation Solar installation for electricity and water heating Rainwater harvesting Decentralized waste water treatment system Improved septic tank

Practical implementations Kamal Meatle at IIT Delhi has discovered that three common house plant can make you healthy and reduce fresh air requirement! Just 3 plants per person can consume all the CO2 liberated by the preson. Hydroponics in window farming is growing trend to have organic fresh food easily available. Gives much O2 at day time Gives much O2 at night time Removes Formaldehyde

Recommendations Initiatives from government… Above 1.50 lakhbuilt up area building have mandatory requirement for MoEF ( Ministry of Environment and Forests )and EIA(Environmental Impact Assessment). Rating system :LEED ,GRIHA. IGBC was founded which facilitates the LEED rating of the U.S. Green Building Council in India Conservation of energy using byelaws MNRE has launched a program on development of solar cities The Bureau of Energy Efficiency (BEE) recommended central government: norms for processes and energy consumption standards, labelling design for equipment and appliances specific Energy Conservation Building Codes (ECBC) and (particularly for green building) to notify any user or class or users of energy as a designated consumer.
