Preface

“Green Buildings are those building in which there is minimum negative impact

to mother nature during construction and operation”

The construction of environmentally friendly buildings is one of the significant

challenges that the World is facing in the 21st century. From environmental perspective,

the building sector is responsible for high energy consumption, waste generation, global

greenhouse gas emissions, pollution and resource depletion. Buildings account for

nearly 30% of the total energy consumption in India, the second highest share of

consumption after industries. To reduce the energy use in building sector, new greener

construction methodology for upcoming new buildings, and retrofit options need to be

applied in existing buildings.

This guideline proposes the Green Building Rating system for Railway Buildings

in India and in addition recommends Green retrofit options to switch from conventional

energy to Renewable energy so as to reduce the dependence on conventional energy

sources. Existing approach for Rating system has been presented, with specifications

reference to ‘GRIHA’ Rating system.

The system is guiding and performance-oriented where points are earned for meeting the design and performance intent of the criteria. Each criterion has a number of points assigned to it. It means that a project intending to meet the criterion would qualify for the points. Compliances, as specified in the relevant criterion, have to be submitted in the prescribed format. While the intent of some of the criteria is self-validating in nature, there are others for example: energy consumption, thermal and visual comfort, noise control criteria, and indoor pollution levels need to be validated on-site through performance monitoring. The points related to these criteria (specified under the relevant sections) may be awarded through monitoring, validation, and documents/photographs to support the award of point. Zonal - Engineering (P & D) Deptt Report in respect of such criteria shall be the binding factor for award of points. The 100 point system consists of some core points, which are mandatory to be met while the rest are optional points, which can be earned by complying with the commitment of the criterion for which the point is allocated. Different levels of certification (one star to five stars) can be awarded based on the number of points earned. The minimum points required for certification is 25. Constructions scoring 25 to 40 points, 41 to 55 points, 56 to 70 points, and 71 to 85 points will get one star, 'two stars', 'three stars' and 'four stars' respectively. A score of 86 to 100 points will get the maximum rating viz. five stars.

Scoring points

The system is guiding and performance-oriented where points are earned for meeting the design and performance intent of the criteria. Each criterion has a number of points assigned to it. It means that a project intending to meet the criterion would qualify for the points. Compliances, as specified in the relevant criterion, have to be submitted in the prescribed format. While the intent of some of the criteria is self-validating in nature, there are others for example: energy consumption, thermal and visual comfort, noise control criteria, and indoor pollution levels need to be validated on-site through performance monitoring. The points related to these criteria (specified under the relevant sections) may be awarded through monitoring, validation, and documents/photographs to support the award of point. Zonal - Engineering (Works) Deptt Report in respect of such criteria shall be the binding factor for award of points. The 100 point system consists of some core points, which are mandatory to be met while the rest are optional points, which can be earned by complying with the commitment of the criterion for which the point is allocated. Different levels of certification (one star to five stars) can be awarded based on the number of points earned. The minimum points required for certification is 25. Constructions scoring 25 to 40 points, 41 to 55 points, 56 to 70 points, and 71 to 85 points will get one star, 'two stars', 'three stars' and 'four stars' respectively. A score of 86 to 100 points will get the maximum rating viz. five stars.

7. Annexure A: Based on earlier Version issued in Jan., 2015.

1.0 Passive solar design of Buildings Green building is an approach to design and construction that respects the environment and conserves resources. It is a common sense approach that create a more cost effective, enjoyable and sustainable buildings. Passive solar design for natural heating and cooling is practiced throughout the world under all climate conditions. As energy costs rise, it is essential to use building orientation, window placements, roof overhangs, reflective barriers and other techniques to control natural solar energy. 2.0 Orientation of Site/Land Plot Site Orientation means the position of the Site with respect to the Cardinal directions. The Site’s orientation is identified by the direction that the front of the land piece faces where building is proposed. When one stands at the Site and faces the road, the direction one face is said to be the Site’s orientation. So, a Site with a road in the North, is called a North facing Site and so on. 3.0 Orientation of the building Orientation of the building is generally used to refer to solar orientation which is the planning of building with respect to solar access. It is guided by natural elements like sunlight and its intensity, direction of the wind, seasons of the year and temperature variations. Site specific planning is very crucial for a nature friendly building and it should be oriented appropriate to the region’s climate. A building may have to take need of multiple orientation factors depending on functional requirements. For example, orientation of the building entrance will have to respect street access, activity zones, and local urban design guidelines. The fact the sun is lower in the sky in winter than in summer allows one to plan and construct buildings that capture heat in winter and reject the heat in summer.


RDSO Page 36 of 87

Thus the orientation of the whole building plays an important role in ensuring such a 'passive solar' process works. As per IS code No.SP-41 (S&T) – 1987 {Handbook on functional requirements of Buildings (other than Industrial Buildings)}, four types of climatic conditions prevails in India: (i) Hot and dry (ii) Hot and humid (iii) Warm and humid (iv) Cold General orientation principles with respect to the above climatic conditions are listed below along with building features and can be used as guidelines. 3.1 Hot and dry climatic zones: Major areas falling in this climatic zone are Delhi, U.P., Bihar, Rajasthan, parts of Punjab and Madhya Pradesh. These areas are far away from coast and maximum day time summer temperature goes as high as 45 degree centigrade and relative humidity as low as 20%. Desirable features of building in this zone are: Orientation: The buildings should be oriented from solar point of view such that longer walls of building should face north & south. Non -habitat rooms can be located on outer face to act as thermal barrier. Preferably, the kitchen should be located on leeward side of the building to avoid circulation of hot air and smell from the kitchen.


RDSO Page 37 of 87

Windows: Large openings with heavy shutters should be provided on northern and western faces as light coming from north is always diffused and indirect. Also direction of breeze, which is from west at most of the places enters from opening on west side. Windows area should be 15 to 20 percent of floor area. Internal courtyard caters for cross ventilation & thermal buffer. Suitable radiation barriers in the form of canopies, chhajjas, long verandahs etc. should be provided on the west side of the building. Sufficient number of ventilators close to the bottom of slab should be provided. Walls: Thick walls, facing the direction of sun are preferred to act as insulating barrier. Walls with light and shining paints on outer surface have good reflective quality and do not absorb heat. The surface of walls should be smooth and non dust catching type. Cavity walls also can be provided as they provide very good thermal insulation. Hollow bricks available in the market can also be used for making hollow – insulated walls. Roofs: Should be built up with good insulating material having slope in windward direction. False ceiling can be used to improve thermal performance of building. Terracing should be provided on the flat roof with mud phuska, lime concrete, foamed concrete or burnt clay block paving over roof slab. Top roof surface should be made reflective by providing whitewashing or any reflective paint. Ample roof overhangs are also important to reducing heat gain in hot climate. They also help in saving energy, providing some spill over space and increase the life span of the building. If cost is an issue, then design the overhangs, only for southwest facing doors and windows. Vegetation: Large shady trees whose roots do not strain foundation and basement should be planted near external walls to provide shade. Special needs: Outdoor sleeping area for summer nights may be provided. Desert coolers and fans can be used during summer months. Therefore, proper space to provide coolers should be planned in the building. 3.2 Hot and humid climatic zone: In this region, the climate is hot and air contains moisture. Mostly interior peninsular region covering the central part of India falls under this category. Sun’s glare is more and undesirable in this region. Relative humidity is above 40% and temperature is above 32 degree centigrade. Interiors should be protected from hot Sun and dusty winds. The thermal characteristics are almost identical to hot & dry zone except that desert coolers are not suitable for hot & humid zone. The orientation and other features of the building would remain the same as in hot and dry climatic zone.


RDSO Page 38 of 87

3.3 Warm and humid climatic zone: This type of climate is normally found in the coastal areas. Coastal regions of Gujarat, Maharashtra, Karnataka, Kerala, Tamil Nadu, Andhra Pradesh, Orissa and West Bengal fall under this category in the region. In this region, mean maximum temperature during summer does not rise beyond 32 degree centigrade and relative humidity ranges between 70% and 90%. Because of less diurnal variation of temperatures along with high humidity, the emphasis should be on prevailing winds. Desirable features of buildings in this zone are: Orientation: should be preferably in North-South direction for habitable rooms i.e. longer walls should face north & south so that shorter sides are exposed to direct sunlight. Windows: Proper cross ventilation of building is of extreme importance; therefore large openings should be positioned on windward and leeward direction. However, openings should be provided with suitable protection like sunshades, chhajjas etc. from Sun and rain. Windows area should be 15 to 20 percent of floor area. The sill height of windows should be at low level between 0.5 to 0.7 m. Fixed windows should be avoided. Internal doorways between drawing & dining and dining to passage etc. may be left open without shutters/leaves. Ventilators should be provided as near to ceiling as possible. Provision of mechanical ventilation for circulation of fresh air as well as exhaust of used air should be made. Walls: Low thermal capacity material be used in construction and walls can be thinner as temperatures are not very high. Compound wall on the windward side should be low. Bare fencing or light screen walls are preferable. RCC jallies are more advantageous as they allow passage of air through them and at the same time provide privacy by obstructing the vision. Roofs: should have large overhangs to avoid rainwater hitting the wall. Roof should be finished with materials of low thermal conductivity. Top roof surface should be made reflective by providing whitewashing or any reflective paint / tiles. Proper slope is essential for effective removal of rainwater. Vegetation: Shrubs of medium height or coconut trees grove or casuarinas, which do not act as wind barriers are recommended. Special needs: Good rain-water drainage is essential. Desert coolers are not suitable in these areas.


RDSO Page 39 of 87

3.4 Cold climatic zone: Cold climate occurs in mountainous regions and plateaus 800 to 1200 metres above sea level. Mountainous regions of Jammu & Kashmir, Himachal Pradesh, Uttaranchal and North Eastern States and other hilly and mountainous regions of the country fall under this category. Snowfall and rainfall is also heavy and mean a daily temperature is 6 degree or less. Minimum temperature may fall up to minus four degrees or even less at some locations. Main requirement of this region is heating during winter months and protection from chilling winds. Walls and roofs should be protected against heavy rain and snowfall. Orientation: Should preferably be in north – south direction i.e longer walls should face north & south to receive more solar heat during winter months. Windows: Glazing windows upto 25% floor area may be provided. Double glazing is preferable to avoid heat losses during winter nights. Walls: Thin walls with insulation from inner side (2.5cm thick insulation) are preferable. Some of the insulating materials are listed in Table 2 of SP41-1987 Part 2 of BIS titled as Handbook on functional requirement of Buildings - Heat insulation. The insulation should be protected against the risk of condensation by providing sufficient vapour barrier like 2 coats of Bitumen, polythene sheet 300 to 600 gauge or aluminium foil on warm side. Hollow and light weight concrete blocks are also quite suitable. Roofs: should be preferably made of asbestos cement or G.I. sheets backed by false ceiling of wood, 2.5cm wood-wool board or equivalent material. The roof should have sufficient slope for quick drainage of rainwater and snow. Vapour barrier should be used depending on location and possible wind pressure. Special needs: Provision for heating of building should be kept like fire places etc. Ceiling fans are not normally required, but may be used during summer on special occasions. Outdoor sleeping area is not required. 4.0 Ventilation system Ventilation is the process of replacing air in any space to provide high indoor air quality. Ventilation is used to remove unpleasant smells, excessive moisture and heat by the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Methods for ventilating a building may be divided into mechanical/forced and natural.


RDSO Page 40 of 87

4.1 "Mechanical" or "forced" ventilation is very effective, however the system require much energy in hot and humid climates. Ventilation increases the energy needed for heating or cooling, however heat recovery ventilation can be used to mitigate the energy consumption. This involves heat exchange between incoming and outgoing air. Kitchens and bathrooms typically have mechanical exhaust to control odors and sometimes humidity. Kitchens have additional problems to deal with such as smoke and grease. Factors in the design of such systems include the flow rate, being function of the fan speed and exhaust vent size and noise level. Direct drive fans like Ceiling fans and table/floor fans circulate air within a room for the purpose of reducing the perceived temperature because of evaporation of perspiration on the skin of the occupants. 4.2 Natural ventilation is the ventilation of a building with outside air without the use of a fan or other mechanical system. It can be achieved with openable windows or vents when the spaces to ventilate are small. In more complex systems warm air in the building can be allowed to rise and flow out upper openings to the outside thus forcing cool outside air to be drawn into the building naturally through openings in the lower areas. These systems use very little energy but care must be taken to ensure the occupants' comfort. In warm or humid months, maintaining thermal comfort solely via natural ventilation may be difficult so conventional air conditioning systems are used as backups. However, with careful planning, energy consumption can be reduced to a large extent. 4.3 Hybrid ventilation is a combination of natural and mechanical ventilation and exploits both systems as required. Hybrid ventilation system utilizes the concept of Thermal lift – the hot waste air rises up, which is supported by the natural or mechanical supply of fresh air as required and ensures that the waste air is extracted naturally and therefore without the use of energy. 4.4 Tuning the Windows: The windows of a building are not just holes in the wall that can be opened or closed; they are actually part of a sophisticated ventilation machanism. For instance, it is known that hot air rises, so if the building have high windows and are kept open, the hot air will vent out. But it can be a lot more sophisticated than that. When air passes over a building, the Bernoulli effect causes the air on top and on the downwind side of the building will be at a lower pressure than on the upwindside. So the low pressure will suck the air through the building.


RDSO Page 41 of 87

4.4.1 Opt for Cross Ventilation Cross ventilation is the natural ventilation method where the air enters through one route and exits through another. It is necessary for the electrical and electronic appliances to vent out the heat which will be removed by the circulating air through cross ventilation, thus keeping the building cool. This is easily achieved by having two windows on the same room facing different directions. Doors and windows should be placed to catch the prevailing breeze and a lower inflow windows and higher outflow windows keeps air moving, as hot air rises.

4.4.2 Install Window Awnings Awnings or screens shade the building by keeping the hot sun rays out during summer. Hence strategically installed awnings for the south and west facing windows can avoid solar heat from penetrating the building. The awnings tend to decrease the heat by 70% and helps to keep the rooms cool to some extent. 4.4.3 Replace Windows with Reflective Glasses The reflective window glass reflects the solar heat outside and also protects by reflecting the harmful UV rays from the sun. Reflective window glass panels in different size are available in the market. For existing window panels, sun control window films can also be applied.


RDSO Page 42 of 87

4.4.4 Install Double glazed windows Double glazed windows are made from two sheets of glass which are separated by a gap of around nine to twenty millimeters and filled with dry air or a special gas. The gap between the glass sheets acts like a insulating material for keeping the heat out. Double glazing is a good option for large windows and also acts as noise barriers. 4.4.5 Shade the windows: The most convenient method of preventing heat is the use of drapes and blinds. Keep the blinds and the window closed during the day time and leave them open for the evening breeze. One should use light shade curtains that has the tendency to reflect heat. One can also use natural shades made of bamboo, jute, reed or grasses. The shades made of grasses can be watered to give cool air, the traditional air cooling method which does not increase electricity consumption. These shades are available in versatile designs and shapes to fit the windows.


RDSO Page 43 of 87

4.5 Hybrid Ventilation System: The hybrid ventilation system functions through two processes. The first process is through thermal lift which allows hot air in the building to rise up which is then released through the vent and is replaced by cooler ambient air. The second process results from the ambient wind driving the turbine, thereby creating flow through centrifugal suction. However when the ambient wind driving the turbine is inadequate, the turbine fan can be shifted to power, and flow rate and so the ventilation, can be increased as required.

4.6 Check the Usage of Heat Emitting Appliances Heat is generally emitted by electrical appliances which run through electricity. It is not possible to avoid but one can minimize the usage of these appliances thus reduce the heat inside. The incandescent light bulbs also consume more energy and emit heat thereby increasing the temperature. LED bulbs are preferred which not only save electricity consumption, but also release negligent amount of heat. 5.0 Natural ways to keep the top floor cool during summer Summer heat is increasing every day and many cities in India record temperatures above 100-1100 F (37.8-43.30C) or even higher. Air-conditioners may be able toward off the heat, but the energy use and electricity consumption bills will be high.


RDSO Page 44 of 87

Top floor is always very hot during summer, because of the roof top happens to be open terrace. Some of the options available are: 5.1 Making the roof reflective, white/metallic colo ur rather than a dark color which

absorbs heat. Many options like the reflective white paints are very expensive. A cost-effective option for painting the roof white is the finely ground lime powder. It is readily available in the market and 5-kg will have to be dissolved in 10 liters of water. Add 500 ml of Fevicol adhesive and then mix well and leave it for 10 minutes, then mix the solution well and painted the roof with a wide brush. It covered about 60 square meters of roof surface. Painted surface is watered after 12 hours and cured. A second coating is applied after 24 hours of the first application. Painted roof can be watered 3-4 times in two days for proper curing. After drying, one can see the bright white roof. A reduction of 5 degrees in ambient temperature can be obtained with painting.

Besides above low cost lime paint, other specialized paints can also be applied as roof coating. Elastomeric Paint contains an elastomeric polymer that allows it to expand and contract along with the material on which it is applied. Apply two coats of bright white elastomeric paint on flat roof to increase its solar reflectivity. Tests with elastomeric paint show a 60 to 75 percent improvement in reflectiveness, which translates into cost savings on energy used for air conditioning.

5.2 Insulating the roof. Insulation between roof and ceiling generally helps in keeping the building warm in winter and cool in summer. It is generally cheap and very easy to do. Insulated surface can be plastered as it is very cost-effective and reduces the moisture absorbing capacity of the structure. Use non-toxic, renewable or recyclable materials for insulation. Cardboard is effective but it does retain water and can burn easily. Soaking cardboard in boron and water makes it more fire-resistant and insect-proof. Boron is biodegradable and less toxic compared to other products on the market. Ensure that Boron soaked cardboard is dried out before placing it. Another option is to apply a single-ply PVC sheathing to the entire flat roof surface. Large polyvinyl chloride (PVC) sheets with heat-sealed seams are available in the market. These sheets with heat-welded seams keep out water and prevent wind damage due to their smooth texture. The good PVC sheathing is warranted to last 10-15 years in varying weather conditions. They also ensure water proofing of roof and greatly prolong its useful life. 5.3 Creating a cold roof Once the ceiling is warm, it means the heat had already entered the living space. Hence the most effective method to keep top floor cool is to create some form of secondary roof to shade the one below. In many climates this would be an attic type construction, but in order to keep cost low, it could just be a vented second layer such as standing seam metal panels on top of spacers to allow for airflow underneath.


RDSO Page 46 of 87

However, the best option available is to install Solar Photovoltaic Roofing Panels over the roof, covering maximum possible surface of roof. One of the advantages of solar panels on a hot day is the shading they provide to the roof. Usually solar panels are placed on a racking system that holds the panels off the roof about 100 to 300 mm. The panels keep the sun rays from hitting the roof surface and slow heat transfer to the attic space. It also helps in powering the building with renewable energy. The average house in India receives more than 600 kWh of sunshine per day. Photovoltaic cells (PVs) convert sunlight directly into electricity, which is stored in a battery system. PV panels are made from semi-conductor material, usually silicon that is chemically treated so that when sunlight falls on them, the upper and lower layers get oppositely charged. An electric current is generated from these opposing charges and flows through an external circuit. A battery pack stores the power until it is needed. The initial cost of PV panels and battery pack is still high however the system can cost-effectively meet large electrical demands. 5.4 Creating a Green roof: A green roof, or roof top garden, is a vegetative layer grown on a roof top. Green roofs shade the buildings below from direct sunlight and reduce both surface temperatures and surrounding air temperatures through evaporation and transpiration, the process by which plants remove moisture from the soil and emit it through their leaves. Roof top gardens are so effective that the surface of a green rooftop can actually be cooler than the ambient air temperature. One can also plant shady trees in the surroundings of the building to shade the roof. However this is more suitable for low height buildings or homes and may take a few decades to work fully. Creepers or tree can be planted over a veranda or yard. During summer, these leafy plants will shade the house. When the leaves are lost during autumn, the bare tree lets the rays into the house through the windows during the colder months.
