Approach to Sustainability

Our values guide what we do and how we work, and we consider Green Thinking to be a clear business advantage. Our approach to sustainability aligns 3 factors – social equity (People), the environment (Planet) and economics (Profit).

We endeavor to construct and develop buildings that minimize risk to health, safety, and the environment and optimize efficiencies in resource management and operational performance.

Aspects of Sustainability Development in our Projects

Energy Efficiency in buildings

At Kalpataru, environmental issues are addressed by reducing the amount of energy required for building operation, and by promoting renewable sources of energy. A holistic energy-efficient approach integrates factors like building orientation, envelope, systems, lighting and other equipment in the design of the project.

  • Buildings are designed and oriented such, that they get optimum exposure and glazing.

  • Use of Energy-efficient lighting such as LEDs, CFLs, T5 and electronic-ballast are promoted to reduce power consumption.

  • CFC, which is a greenhouse gas known to cause ozone depletion, is a widely used refrigerant. However, only CFC-free refrigerants are used in Kalpataru’s projects.

  • Solar water-heating systems are provided for projects in Thane and Pune region.

  • Double-glazed windows using high performance glass, with low SHGC and u-values are used in commercial projects.

Rain Water

Harvesting

In India, majority of the people are dependent on monsoon, where rainfall extends from June to October and much of the precious water is lost as surface runoff. Hence, it is important to conserve and recharge natural aquifer to ensure that this essential resource for life is not depleted.

Our Projects are designed to control Ground Water Depletion by employing the following Rain Water Harvesting (RWH) schemes designed by specialized consultants.

  • Identifying the Rain Water Harvesting (RWH) potential of an area with use of Hydro-geological study from experts.

  • Diverting maximum surface runoff from stormwater drains and total rooftop runoff to Rainwater Harvesting system.

Shadow Analysis

The effects of shading by one building upon another can be either positive or negative depending on the site-specific circumstances of the properties involved. A potential benefit of shading for adjacent structures may be a cooling effect gained during warm weather. Negative consequences of shading include the loss of natural light for passive or active solar energy applications or the loss of warming influences during cool weather.

While designing high rise buildings, a Shadow Analysis (basically a 3D model, prepared for the project building and its immediate surroundings which can get affected or affect the project building) with the use of softwares like ProgCAD, Ecotect and Virtual Environment is done. This helps to assess the impact of shadow on neighbourhoods.

The help of weather data file from Indian Society for Heating Refrigeration and Air Conditioning Engineers (ISHRAE) is also enlisted to find out the sun path diagram.

Indoor Environment Quality

Factors such as Daylight, ventilation and indoor air quality influence the health and well being of the occupants of the building.

At Kalpataru, in most of the projects, the following provisions are given importance during the design stage:

  • Daylight and Ventilation: Optimizing the size of window openings to ensure adequate daylight and fresh air ventilation. This ensures connect with the exterior environment and avoids the possibility of indoor contaminants from polluting the air quality.

  • Cross Ventilation: Outdoor openings in at least 2 directions (wherever possible) for better cross ventilation.

  • Low VOC paints- Volatile Organic Carbons (VOCs) used in paints are known to cause diseases of the respiratory tract. Only low VOC paints are used in Kalpataru’s projects to ensure healthy indoor air quality.

Heat-Island Effect

‘Heat islands’ are described as developed areas that are hotter than nearby less developed areas. They are parts of the urban development where there is a steep temperature variation between developed areas and cooler surrounding areas. Heat Islands are detrimental to the local ecosystem

In most projects at Kalpataru, a building’s roof, non-roof and podium are designed with the following considerations:

  • Covering building’s exposed roof areas by materials with high Solar Reflective Index (SRI).

  • Vegetation in roof and podium areas.

  • Shaded/ Underground parking.

High SRI tiles for roofing surface helps to reflect the sun’s warmth into surroundings. As a result, the ambient temperature in developed areas is lowered, which helps to reduce cooling load and energy consumption.

Wind Analysis

Wind analysis of high-rise buildings helps in predicting the wind pattern in the surrounding areas of the building. This enables the designer to make decisions with respect to layout of the building, the orientation of the building, placement of windows and other aspects.

While designing high-rise buildings Wind Analysis is done with help of IES software to understand the impact of proposed high-rise buildings (which are above 70 meters in height) on its immediate surrounding buildings.

This study helps to adopt the following eco-friendly measures:

  • Appropriately place openings to get the most out of cross ventilation.

  • Decide on the orientation of the building to get maximum air flow.

  • Assess the impact of wind on architectural features provided in common areas.

Water Conservation

Water is one of the most important natural resources to sustain life on the planet. So long as the demand for water continues to increase, the problem of water scarcity will continue to persist, making conservation of water the only way forward. Every effort is being taken to minimize water wastage in its projects.


Some of them are as follows:

  • Installing water efficient fixtures such as low-flow and dual-flush toilet fixtures which not only reduce water demand but also saves energy and resource required for storage.

  • Waste-water generated within many of our projects is treated and recycled, to entirely meet the water needed for landscaping and sanitation purposes after proper onsite treatment through specially-designed on-site Sewage Treatment Plant (STP). This reduces the demand for fresh water, and reduces the load on the municipal sewage system.

Waste Management and Disposal

During the construction phase, recycling of construction, demolition wastes and land clearing debris reduces demand for virgin resources and has the potential to lessen the environmental and health burdens associated with resource extraction, processing and transportation.
Kalpataru has addressed this challenge in the following manner:

  • Managing construction debris by using it within a site to the maximum extent possible for filling, levelling and for water proofing

  • At Kalpataru, convenient recycling opportunities for all building occupants have been created to divert a significant portion of Solid Waste from Landfills by:

  • Educating & giving ideas to occupants on household waste segregation benefits.

  • Treating wet waste using Organic Waste Converter/ Bio -composting/ Vermicomposting, thus minimising land, water and air pollution by diverting waste from municipal landfills.

Traffic Analysis

Although transportation systems define urban development, in many cases new developments themselves become one of the major causes of traffic congestion in many of the bigger cities. To deal with this, during the development of a new High Rise projects at Kalpataru, the following are specifically studied:

 

 

  • Actual traffic volume measurement by video recording at intersections.

  • Traffic related surveys to find out growth over a specific period.

  • Change in air quality with increased vehicular traffic by Dispersion Modelling using Enviver software.

  • Conduct Emission Inventory study for project region

Kalpataru also makes provisions to overcome traffic congestion problems for the present and the future at project sites by ensuring:

  • Sufficient parking space.

  • Reduction of points of conflict at project entry and exit points.
