Most of global warming is being caused by increasing concentrations of greenhouse gases produced by human activities.
A greenhouse gas ( GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.
Percentage contribution to the greenhouse effect on Earth the four major gases are water vapor 36–70%carbon dioxide 9–26%Methane 4–9%ozone, –7%
The most largest driver of global warming is Carbon dioxide (CO2) emissions from fossil fuel combustion Cement production and land use changes such as deforestation.
Objective:
Ensure shelter safety against Flood, Fire, theft, Earthquake , etc..
Effort to build sustainable homes
Objective:
Self-reliance building in Energy (Zero Energy Building)
Optimum utilization of Land & Building
A green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building
Energy – Electricity Produced at site. Avoid Transmission loss.
Waste – Solid waste recycled. Avoid transportation.
Water – Water taken at site and wastewater recycled.
Project Analysis
Pre-occupation – Planning and During Construction
Post-occupation – After Client occupation and Maintenance

Save Rs 500 per annum
Control 0.07 ton of CO2e emission
Reduce Noise pollution
Safety against theft
Situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified
SBS – Effects1. Sensory irritation of the eyes,
nose, throat 2. Neuro toxic or general health
problems 3. Skin irritation 4. Nonspecific hypersensitivity
reactions and odor and taste sensations
Mo(u)ldMold is a fungus that grows in the form of multicellular filaments called hyphae, produce mycotoxins that can pose serious health risks to humans such as watery, itchy eyes, a chronic cough, headaches or migraines, difficulty breathing, rashes, tiredness, sinus problems, nasal blockage and frequent sneezing.
Mold in the home can usually be found in damp, dark or steamy areas e.g. bathroom or kitchen, cluttered storage areas, recently flooded areas, basement areas, plumbing spaces, areas with poor ventilation and outdoors in humid environments.
To reduce moisture levels that
can facilitate mold growth. Removal of affected materials after the source of moisture has been reduced and/or eliminated may be necessary for remediation.
Snake plant or mother in law tongue
(Sansevieria )purifies toxin in air
Crassulacean acid metabolism- can get oxygen in night time also
Building Flush out
Period to reduce possible indoor air quality contamination after construction completion and prior to occupancy.

Avoid purchase of 20 Liters drinking water can approximately 120 Nos. per year
Save Rs 3,600 per annum
Biodegradable waste Kitchen Food waste and vegetable waste used for Biogas plant and get Biogas for cooking
Embodied energy is the total energy required for the extraction, processing, manufacture and delivery of building materials to the building site.
Energy consumption produces CO2, which contributes to greenhouse gas emissions, so embodied energy is considered an indicator of the overall environmental impact of building materials and systems
Example: Material - E.E inMJ/Kg - E.C in Kg
Cement 4.6 0.83 Steel 24.4 1.77 Bricks 8.4 0.62 Aluminium 155 8.24 Timber 8.4 0.46 Glass 15 0.8 Paint 20 1.0 E.E - Embodied Energy
E.C - Embodied Carbon
The clay brick kilns emit high concentration of carbon monoxides, NOx (nitrogen oxides) and oxides of sulphur (SOx) that are harmful to eye, lungs and throat. These air pollutants stunt the mental and physical growth of children.
Also, nearly 25 to 26 per cent of the country’s wood production are used for burning bricks every year, causing deforestation.
Digging the clay (approximately 3.5 kg per brick) from land affects the agriculture and mass imbalance.
LCA is a technique to assess environmental impacts associated with all the stages of a product's life from-cradle-to-grave i.e. Construction to demolition.
Here we assume life of Building for 40 years.
1. Procurement - Embodied Energy
We can't build without E.E, but we can reduce and save.
2. Construction – Operational Energy
We can't construct without O.E, but we can reduce and save.
1. Post occupation – Operational
Energy We can control O.E after client occupation by replacing renewable sources.
2. Renovation and repair works– Operational Energy
We can’t eliminate but we can limit the scope of works.
3. Demolition Energy –Operational Energy
We should spend some amount of energy.
Energy-Electricity
Approximately we can replace and save electricity 10 unit per day -3650 unit per year
And save transmission loss approximately 1564 unit (30%) (5214x0.7=3650)(5214-3650=1564)
Water
Save 4380 Liters per year and replace 1 person water consumption for 32 days or 4 persons for 8 days
Approximate calculation
For 1 person each flush save 3 Liters per day
For 1 year 3 x 365 =1095 Liters For 4 persons 1095 X4= 4380 Liters per year
Per capita 135 LitersFor 1 person 4380/135= 32 daysFor 4 persons 32/4= 8 days
Indirectly we can save water.
(0.0005925 metric tons CO2 per kWh) ie for 1 KWh power production 0.5925 Kg coal required. ( For mining one tonne of lignite, about 13 tonnes of water has to be pumped out) ie for 1KWh power production 7.7 litres to be dewatered.
Solid Waste disposal
Approximately reduce 250 Kg Solid biodegradable waste disposal per year (0.7 Kg per day) and avoid transportation.
Rain Water Harvesting
Save 22,275 Liters per year and fulfill 1 person water consumption for 165 days or 4 persons for 41 days
Approximate calculation
Roof top Area – 55 SqmAnnual Rain fall – 900 mm avg Assume 50% ProbabilityAnnual Rainfall -450mm Co efficient 0.9Total Rain water Harvesting -55x0.9x450 =22,275
LitersPer capita 135 LitersFor 1 person 22275/135=165 daysFor 4 persons 165/4= 41 days
Approximate calculation
Assume Per capita 70 Liters per day
For 1 person for 1 year 70 X 365 = 25,550 Liters
For 4 persons 25,550 X 4= 1,02,200 Liters
Approximate calculation
Electricity 3650x5 =Rs 18,250 LPG cylinders - 450x3 =Rs 1,350Vegetables approx-150x12 =Rs 1,800Drinking Water -120x30 =Rs 3,600Total =Rs 25,000 per year
Teak wood after 30years 1 tree 20 cft X Rs 2,500/cft = Rs 50,000For 10 trees = Rs 5,00,0001 tree 20 cft X Rs 10,000/cft = Rs 2,00,000For 10 trees = Rs 20,00,000
Approximate calculation
Demand 550 liters per day per person
Supply 210 liters per tree per day 2.5 trees fulfill one person
requirement A family of 4 persons can be supplied
enough supply of Oxygen in daytime by 10 trees
Top soil preservation (anywhere)
For one brick digging the clay
approximately 3.5 kg. For one ordinary residential building 15,000 Nos. x 3.5 Kg = 52,500 Kg
or 52.5 tonnes.
Environment Approximately we can control 2.5 tons of Equivalent CO2 emissions per year by Solar panels, windmill, solar water heater, etc
