Architecture designs are the imagination of our thought process, that also provide green solution for building too, Architects work with all these providing techniques and solutions here some new and important techniques would be explained.
Green roofs are solution for maintain temperature of top floor in the building, that are basically layers of material installed on terrace of a building. It can be installed on either flat or pitched roofs to help manage storm water. Green roofs contain layers of soils, waterproofing membrane, and drainage or water storage systems.
Green roof are one of the tool that can help mitigate the negative effects of air pollution. In this article encompasses published research to date on how green roofs help mitigate pollution and how green roof materials influence the magnitude of these benefits. Also concentrates on how green roofs influence air pollutants, carbon sequestration and storage, and how to improve carbon potential.
Green Roof vegetation helps to filter out dust and smog particles. Nitrates and other harmful materials are absorbed by the plants out of the air and rainfall and bound within the substrate. Planted areas are natural sound insulators and absorb more sound than hard surfaces.
There are several types of green roofs divided into the categories of intensive, extensive, modular, and brown or eco roofs
Reduce the storm water runoff rate from a roof by up to 65%
Make roof surfaces 30-40% cooler.
Reduce heat flux from roof to building by up to 72% Last 40 years or more.
WRI India is lead stakeholder and policy engagement for its projects within the Climate Program. They will lead stakeholder engagement activities including the design, planning and organization of consultations, dialogues and workshops to support the Climate
They will also contribute to the design and organization of capacity building programs for government officials on strengthening climate action planning. That contributes to writing policy briefs and reports based on policy analyses, policy dialogues and stakeholder engagement.
Focus on integrated solutions that can enable a low-carbon transition in India, while ensuring that the transition is equitable and just for its people and protects natural resources. Through applied research, the use of frameworks and tools, partnerships with key stakeholders and ground-level implementation, we seek to achieve impact at scale.
Green Roof
Green Roof has many benefits at economic, ecological & social level. A green roof provides a rainwater buffer, purifies the air, reduces the ambient temperature, regulates the indoor temperature, save energy and encourages biodiversity in the city. Green roofs are part of climate-proof construction. What’s more, people are happier in a green environment than in grey surroundings.
Provide Rainwater buffer
A green roof absorbs rain water by the water buffering in the plants, substrate and drainage layer. This delays the discharge of rainwater to the sewage system, purifies the rainwater, and water also evaporates through the plants. This all helps to stabilize the groundwater level, reduces the peak load on the sewage system and reduces the risk of flooding.
Quality of the air
The plants in a green roof filter particulate matter from the air and convert CO2 into oxygen. With a green roof you are contributing to air purification.
Reduce temperature
Plants absorb sunlight, 50% is absorbed and 30% reflected; so this helps to create a cooler and more pleasant climate.
Increase solar panel efficiency
A green roof reduces the temperature on the roof.
Reduce Noise
A green roof acts as a sound barrier to your building. It absorbs sound and thus provides a quieter environment, both inside and outside your building.
Extend life span of Roof
A green roof protects the roofing material from external influences such as the sun, rain, wind and temperature.
Blue-Green Roofs
Blue-green roofs assemblies are typically mounted as outer layers on top of compact, flat roof structures. The principal layers of the blue-green roofs are the plants themselves, the substrate in which they grow, and the layers for water storage and drainage. Multiple conceptual variations exist for each layer, most notably in the method of water storage. Water storage may occur in the form of standing water filling cups or boxes water absorbed in porous materials or pooling directly on the roof membrane.
As building blocks towards sustainable urban development, more and more green roofs are being realized. A green roof offers many benefits in terms of sustainability, the environment and perceived value. The vegetation converts CO2 into oxygen and filters particulate matter from the air. This is better for the climate and for health. In urban areas in particular, green roofs can significantly improve air quality.

Green roofs as sustainable solution
Green roofs also contribute to the sustainability of a building. A green roof significantly reduces the need for air conditioning in summer and provides insulation in the winter. The insulation in the winter will depend on the amount of moisture in the various layers. Insulation in the summer is the greatest, because the layers are dry and therefore reflect the heat effectively. Due to the reduced need for air conditioning in the summer and less heating in the winter, a green roof significantly reduces energy consumption.
A green roof also extends the life span of your roof, because it shields the roofing material from the harmful influence of sun, wind and rain. Research has shown that roof surfaces last two to three times longer if a green roof is installed. What’s more, the roof has a water buffering function, because it holds the excess water from heavy rainfall and releases this gradually to the sewage system. This prevents flooding and ensures a lower ambient temperature through evaporation. In addition, a green roof provides scope for biodiversity to develop. There are shelters and nesting sites for birds, bees, butterflies and other insects.
Conclusion
Architecture gives a productive impact on the city or society, which can feel in everyday life. We have to learn about our ancestors and their lifestyle through these built spaces. It is directly proportionate to our culture and religion. As our future also will have many changes to show reflect through architectural constraints. With all these aspects in consideration, the impact of architecture on our lives is significant as it has always been. Be it environmental, economical, or ethical, architectural practices will always play a vital role in upgrading our living towards a sustainable future.
Green roofs have the ability to moderate some of the environmental consequences of the last and present centuries, improve biodiversity in our cities as well as create remarkable spaces where people can work, relax, and grow food. They can provide real, measurable socially important ecosystem services. However, they should also be seen as part and parcel of a biophilic urban realm, as part of green infrastructure where the sum human and environmental benefits is greater than the individual parts. We should celebrate every green roof that is installed, either as a new build project or as retrofit. Clients and owners who specify green roofs should be encouraged and praised as they are not only providing benefits for themselves but their roofs provide tangible health and well-being benefits for the wider community
