Green Buildings are the only solution for a Cleaner, Sustainable Future in the Urban Landscape

plausibly “Green Buildings are a hallmark of economically sound business decisions, thoughtful environmental decisions & smart human impact decisions “ – Rick Fedrizzi

Green Building Construction is any practice involved during construction of a building that limits the burdens of that practice on the environment.

Green Building looks far beyond reducing energy use and improving air quality. It takes into account a big picture approach, focusing on the inter-relationship of the various building systems – plumbing and HVAC, electrical, structure, exterior building facade, and interior finishes – rather than considering each one independently.

As a construction company with a strong belief in environmentally friendly practices, we at BLK believe Innovation is one of our core strengths.

In the pursuance of this core belief, we encourage our colleagues to identify the best solutions and technologies for our clients to make their buildings in the fastest way possible with the highest levels of quality, safety and efficiency while executing our projects. We do this in tandem with making sure our technologies are keeping environment conservation in mind.

Today, going ‘Green’ has become the need for the future, BLK has steadily become a strong player in the certified Green Projects category in the country. Since most of the IT parks, IT offices and MNCs are opting for “green” building, and most of these projects that are being constructed are LEED silver, gold or platinum rated, we at BLK are aiming to deliver cutting-edge technologies to meet the ever-evolving demand. In the pursuit of the same, Hines One Horizon Centre (Gurgaon), Bharti Realty Worldmark (Aerocity), Embassy Tech Village (Bangalore) & Hero Factories are some of the recently completed LEED Gold & Platinum certified constructions executed by our company B.L Kashyap & Sons.

Not just building ‘Green Projects’, but also doing our bit for the environment is a part of the core DNA of BLK. An example of the same has been demonstrated at the time of Hines One Horizon Centre project construction, where BLK made sure that the topsoil being removed was re-used for landscaping and the sedimentation pit has to be provided to avoid soil erosion in excavated areas. We ensure to adopt such techniques at every stage of construction of various projects across categories in order to achieve desired results.

Over the last several years, green building construction has seen a dramatic increase in India. India has the second largest green footprint at 3.59 billion square feet. Green buildings are projected to grow 20 percent in the country by 2018 estimated to be at 10 billion square feet by 2022. The leading drivers of this growth are client demand, environmental regulation and an enhanced awareness of the occupant and tenant benefits of green buildings. Energy shortage in the country has also further pushed developers to opt for the “Green” options, which in totality is beneficial for all stakeholders.

To achieve this, use of high-quality green building materials ensure that the project meets the stringent green building norms, as far as possible we avoid using materials that have a negative impact on the environment and do not result in huge wastage, making it an essential practice for green buildings. Material resource efficiency and conservation are key factors in meeting stringent green building norms as they are one of the default components that make the building “Green” certified.

New green technologies and materials are always being developed and are entering the marketplace to complement current practices in creating greener environments. However, many of these technologies and materials have not been tested long enough in the built environment in order to fully verify their performance, hence we seek extensive testing and performance data before incorporating new technologies and materials into a project.

Some of the unique eco-friendly and energy-efficient Green Building projects that BLK has constructed include:


  • High performance glasses DGU’s (double glazing units) used in façade system to achieve less thermal transmission and better acoustic properties
  • Façade is treated in such a way that the shading devices are provided to reduce the use of air conditioners
  • 85% of the external surface is glass which increases light transmission. 4.05m floor-to-floor height to harvest maximum natural light
  • Heat recovery wheels to pre cool the fresh air. Combination of water-cooled and air cooled chillers to achieve better energy efficiency. High performance chillers to achieve better IKW rating
  • Use of thermal energy storage system to reduce the power consumption by running the chillers at night
    Basement ventilation system to maintain air quality in the basement
  • BTU meters to monitor the energy consumption for cooling at each floor level – minimizes the wastage of chilled water
During Construction:
  • Topsoil being removed and reused for landscaping
  • Sedimentation pit to avoid soil erosion in excavated areas
  • Organic waste converter and separate e-waste storage facility – where e-waste to be recycled by government-authorized vendors
  • Sludge from STP is used as manure for green landscape
  • Low flow sanitary fixtures (2/4 LPF) and (1LPF for urinals). Sewage treatment plant for reusing water for flushing
  • Roof top rainwater harvesting and reuse for domestic purpose
  • Rain water-harvesting pit to recharge the ground water and use of treated water for landscaping
  • Car charging points in the basement. High efficiency low loss dry type transformers
  • Individual energy meters for tenants to monitor the consumption of power at each stage


  • Dual Pane high performance glass cuts heat and noise while allowing natural light
  • Chillers with VFDs (Variable Frequency Drives) that optimize chilled water flow and minimize operation costs
  • Energy Efficient lighting systems with emphasis on Day lighting (Bringing sunlight deeper into the building through design innovation)
  • Use of CFLs; Correct building Orientation keeping sunlight and wind factors in mind
  • VAV system of air-conditioning to optimize air flow and decrease operating costs
  • Sensors for operating and managing VAV/HVAC
  • Natural gas based power source to fulfill energy demand

All of the above resulted in 14% reduction in energy demand as compared to a standard building.

  • Extensive storm water management
  • On site sewage treatment plant
  • Rain water harvesting & water recycling
  • Low flow fixtures and automatic sensors
  • Cobble stones and pavers used in Hard scape that promote the natural water cycle
Indoor Air Quality:
  • CO2 sensors to enable good levels of fresh air within building
  • CO sensors in the basement to maintain good air quality
  • External AHUs with UV filtration that prevent harmful microbes to enter the air conditioning systems
  • Low toxin emitting materials for interior finishes
  • Procurement of locally available environmentally friendly materials for construction
  • Use of non-hazardous paints, water proofing compounds, sealants etc.
  • Use of composite wood products
  • Recycling of sheeting systems
  • Using materials in hardscape and landscape that promote natural water cycle
  • Green Roofs covered with vegetation planted over water proofing membrane, create artificially altered surfaces by high thermal reflectance and high thermal emitting
  • Over 30% of soil cover retained
  • Minimized surface heat reduction
  • All landscape maintained through recycled water
  • Water sensitive plant groups used
  • Organic waste composite used for landscaping

The above mentioned case studies of projects that followed best practices required to limit negative impact on our environment is dependent on a lot of pre existing conditions that sometimes hamper implementation. However if knowledge is shared and benefits are highlighted and understood by the Builders and the end users, we will leave a healthier and safer environment to our future generations.

The onus lies on us to make that difference.
