Sustainable Building Design
Our technical knowledge, engineering heritage and multidisciplinary experience positions us aptly to partner with clients, from strategy through to solutions design and implementation. Facilitating modern principles, like digital design, occupant-centric design, biophilic design principles and design for carbon neutrality, we often are a part of the core team focused on exemplary project delivery. The passion and drive of the team to be innovative and pioneers allow for an “out-of-the-box” thinking approach, enabling outcomes which exceed the Clients' expectation - from both the resilient design and efficiency perspectives.
Our Services Include:
1. Wind Flow Anaylsis
We study the historical wind patterns of the locations and study the wind movement patterns across the proposed masterplan. We use the results of this analysis to advise our architectural planning partners to optimize the following:1. The spacing between buildings.
2. The street width.
3. Size of the courtyards between different wings.
4. The location of water bodies on the masterplan to enhance evaporative cooling.
2. Shading, Massing, Daylight, Glare and Lighting Simulation
We model the placement of various buildings on the campus to study solar radiation on the façade and advise the architects on1. Self-Shading strategies.
2. Optimal spacing between buildings to reduce the direct solar heat gains.
3. Placement of trees and vegetation to reduce the glare.
4. Placement of buildings/trees to improve walkability across the masterplan.
Daylighting without glare helps create a visually stimulating and productive environment for building occupants. As part of the daylighting study, we model the entire building and study the light penetration and distribution of the lighting and advise our partners on the optimum parameters for:
- Building orientation
- Climate responsive window to wall ratio with the optimum balance between daylight and heat gain
- Optimized floor footprint
- Glazing selection
- Vertical and Horizontal solar shading devices and their proportion to avoid excessive glare
- Location and proportion of Light shelves to improve the light penetration in project with deeper floor plates.
- Use of dynamic facades, skylights, and tubular daylighting devices
- Daylight responsive lighting controls
- Daylight responsive furniture design and placement
3. Facade Optimization & Panelization
Façade designing can be categorized into various types like intelligent facades, Climate responsive facades, Interactive Facades etc.For the Climatic responsiveness and Efficiency aspects of a façade design, we consider the following fundamental parameters:1. Building orientation.
2. Altitude angle & Azimuth angle of the site.
3. Thermal performance of a building envelope.
4. Glazing Systems.
4. Energy Modelling & Sensitivity Analysis
Our building energy modeling experts model the entire building and the various mechanical systems and optimize the total annual energy consumption. They carry out the following studies.
- 8760 hours Heat load analysis
- Building envelope study for energy and cost optimization
- Modeling of different HVAC systems
- Comparison of the annual energy consumption between different options
- Comparison of cost of each system
- Recommendations based on ROI and serviceability of each system
- Modeling for code compliance and green building certification compliance
5. Passive Design
Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building to improve the indoor thermal comfort along with low or nil energy consumption. This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural cooling). Some of our passive design techniques include1. PDEC system design.
2. Earth Air Tunnel.
3. Stack Effect.
4. Natural Ventilation.
5. Radiant Cooling system.
6. Evaporative Cooling.
7. Displacement Ventilation.
8. Roof Spray System.
9. Night Sky Cooling.
10. NChilled Beams & Chilled False Ceiling.
11. Ground Source Heat Pump
12. Roof Pond Cooling
6. Sustainable Master planning
The Sustainable Design Guidelines are meant to illustrate sustainable design strategies and concepts that focus on the appropriate and efficient use of resources —water, energy, air, materials, and land — to reduce the development’s environmental impact during its lifecycle, and to make the whole development a highly ‘sustainable living community’ space. The report summarizes the product & technology research conducted by the Sustainability Team and describes those products & technologies that will likely be the most useful for and relevant to Development.
Through the implementation of the guidelines the development will:1. Minimize its ecological footprint.
2. Achieve a sustainable building and community design.
3. Enhance the development’s air and water quality.
4. Have an increased operational efficiency.
5. Achieve a clean community, where the environment is protected from pollution.
6. Prepare the community for future and make it resilient
7. Be a healthy community, where highly liveable outdoor environments encourage opportunities for excursive activity and interaction.
The indicators are grouped into broad areas covering environmental, social, cultural, and economic criteria for sustainability. This covers the following1. Land use & Ecology
4. Energy & Climate Change
6. Materials Recycling & Waste
8. Place Making
9. Cultural & Perceptual
10. Cost & Economics
7. Computational Fluid Dynamics (CFD)
CFD has been playing an increasingly important role in building design, following its continuing development for over a quarter of a century. The information provided by CFD can be used to analyse the impact of building exhausts to the environment, to predict smoke and fire risks in buildings, to quantify indoor environment quality, and to design natural ventilation systems, etc.
The ventilation study in buildings is done to find a thermally comfortable environment with acceptable indoor air quality by regulating indoor air parameters (air temperature, relative humidity, air speed, and chemical species concentrations in the air).
CFD finds an important role in regulating the indoor air parameters to predict the ventilation performance in buildings.
Following Services will be done under CFD analysis.
- Temperature Analysis
- Air Flow
- Contaminant Distribution
8. Health and Well-Being
This involves making the buildings healthier and more valuable with indoor environmental quality programs.
9. Water Self Sustainable Development & SUDS Design
We see water in context. From delivering a water based infrastructure to advising on natural catchments, we consider commercial, economic, environmental, and social implications.
The goal is to ensure that the development maximizes water conservation by optimizing the utilization of on-site water resources, minimizing waste water outflows, by maximizing water use efficiency within buildings and on site, while reducing potable water requirements, and by generating water on site.
Following Services will be done as a part of Water engineering:
- Catchment Analysis
- Water Self Sufficiency Analysis
- Storm water Control Strategies
- Constructed Wetland Design
- Rainwater Harvesting Strategies
- Water Modelling
- Integrated water Resource Management
10. Renewable Energy & System design
To avoid dependency on the utility connection we encourage onsite energy development and its usage:
A typical Renewable Energy design includes the following elements:
- Solar photovoltaic
- Combined heat and power (CHP, or cogeneration)
- Electricity Generation from Biomass
- Micro Turbines
