Introduction• Design passive residential complex(PRC) using

green building codes and architecture itself to reduce greenhouse gases (GHGs).

• More than 1/2 of all GHG emissions in world come from building operations

• Our target is to design GHG neutral residential complex using carbon-neutral measures in areas such as lighting and heating technologies.

• Passive design elements, when evaluated in terms of relative cost and effectiveness.

• Reduces a building’s energy demand by as much as 50 percent.

• It also helps us in creating a more sustainable architectural form across the city.

• Passive design refers to an approach that discourages reliance on mechanical systems for heating, cooling and lighting.

• Instead harnesses naturally phenomenon such as the sun, wind and other climatic effects

• It maintains consistent indoor temperature and occupant’s comfort.

• It can help to reduce or even eliminate utility bills.

• Improves the comfort and quality of the interior environment

• Reduces GHG emissions associated with heating, cooling, mechanical ventilation and lighting.

• High level of insulation with minimal thermal bridges

• High level of utilization of solar and internal gain

• High level of air tightness

• Good indoor air quality

• Non-mechanical ventilation system with highly efficient heat recovery

Core strategies of Passive Design

Road Map to our Project• Assessment of various guidelines of IGBC, Griha,

Leed, and other green building codes.

• Preparation of outline for the design & assessment of various factor like sun chart, wind flow chart, etc.

• Preparation of layout of residential complex on AutoCAD.

• Structural designing of residential buildings and other structures using software STAAD-PRO.

• Analysis of structure under seismic loads and wind load using STAAD-PRO.

• Computation of various details of reinforcements using STAAD-PRO.

• Facade designing(i.e. designing of glass windows and doors) according to day lighting.

• Designing of passive lighting systems, heating & cooling system, rain water harvesting system for complex, temperature and sound insulation.

• BIM model analysis & 3-D rendering of residential complex using software Google SKETCH-UP

• Cost Evaluation of Passive Residential complex.

• Evaluation of residential complex on the basis of Griha and Leed.

Elements of residential complex

Multistorey Villas Utilities

Club Swimming pool

Other utilities

3-D designing of multistory building

KEY FEATURES OF BUILDING 1. Roof

• It consists of solar photovoltaic cells for generation of electricity.

• A solar water heater for supply of hot water which is further used in household works as well as generation of electricity.

• It also serve as a green house for urban farming , terrace is also used for growing food items and waste water treatment.

2. Rain water harvesting system • Rain water harvesting system is being installed in

the building. • It collects the rain water and stores it into storage

tank for usage in purposes like irrigation, car washing etc.

• Also a natural reed based treatment plant has been setup for collecting and recycling of waste water

3. The building is being designed in such a way that it consist of large windows on three sides so that maximum natural light can enter the building and devices have been in order to allow only light to Enter the building and not the radiation and heat.

4.Trees are placed strategically in order to ensure maximum benefit, high trees are being placed in east and west direction prevent direct radiation and deciduous trees are being placed in south direction to allow sunlight in winters.

5. Temperature Control

• Various techniques are being used in building in order to maintain suitable temperature according to season, and weather.

• A earth air tunnel is being installed which gives hot air in cold weather and cold air in hot weather

• Also materials used in building are energy efficient and takes time in heating or cooling by action of weather.

6. Waste disposal

• Waste disposal is also taken into considerations, first biodegradable and non- biodegradable waste is separated.

• Then biodegradable waste is sent into vermin composite tank, also the heat generated in process is being used in the building.

7. Materials used in the construction are green materials, cement consist of a good proportion of fly-ash, also the un-earthen is being processed and is made into use for various purposes, recycled materials are being used in building wherever possible

Layout of flat in multi-storey building

Details of plan

• Each floor consists of four flats, two lifts and common area.

• Gross area of each flat is 1200 sq ft.

• Built-up area of each flat is 1054 sq ft.

• Total area covered by each floor is 5381 sq ft.

• Each floor has 581 sq ft as common area.

Structural Designing of multi-storey building in STAAD-PRO

Cost & Estimation• Cost of Concrete= Rs 5154642.46

• Cost of Steel bar= Rs 3903562.5

• Cost of Brick Work = Rs 970702.4

• Cost of Plastering = Rs 700826.4

• Cost of Glass = Rs 350000

• Cost of Solar Panel = Rs 5250000

Total cost of Project=Rs 16,559,733.76
