At work to help you build a Sustainable Future

EnerArch is a consulting firm that provides a unique perspective on performance driven building design, construction and operations that is unparalleled in the industry.

Sustainability is rooted in the balanced interactions between society, the economy and ecosystems. While humans are part of this ecosystem, our current pace of consumption of resources is causing an imbalance and confronts us with increased risk from environmental, economic and social threats.

Our clients most often see sustainability as a combination of challenges and opportunities. The key issue is to determine how to best address and minimise challenges while maximising opportunities, such as identifying practices that will reduce resource consumption while also reducing costs. Our clients are experiencing environmental and regulatory pressure, changing performance standards, and increasing stakeholder demands.

EnerArch has a history of helping evolve these challenges into opportunities for our clients by increasing efficiency and performance, driving innovation, reducing risk, and improving public perception.

EnerArch proposes to engage the project team in a fully integrated process to ensure that the requirements to achieve the desired ratings are fully understood and complied with.

EnerArch would work with the project team to identify the opportunities and potential obstacles affecting sustainability and guide the team in establishing ambitious but achievable sustainability goals within the project’s site, budget and operational constraints.


What We Do

3D Modeling & Visualization


ECBC Compliance

Energy Conservation Building Code (ECBC) inacted in 2001 means the norms and standards of energy consumption expressed in terms of sqm of the area wherein energy is used and includes the location of the building. It sets minimum energy performance standards for design and construction of new building with connected load of 100 kW  or contract demand greater than 120 kVA (2009 amendment) and above. It is recommended for all other buildings.

The ECBC compliant building’s energy consumption would be at least 30-40% less energy compared to a typical building in India.

Compliance Approach

  1. Prescriptive Approach
  • Each component must meet minimum performance standard
  • No Flexibility
  1. Trade off Approach
  • Flexibility in minimum performance standard for each component but overall systems performance must comply with ECBC requirement.
  • Experts advise, Energy simulation and Building Performance modeling techniques are required to demonstrate compliance
  1. Whole Building Performance Approach
  • Complete flexibility in ECBC compliance requirement
  • Actual building is compared against ECBC reference building.
  • Experts advise, Energy simulation and Building Performance modeling techniques are required to demonstrate compliance.
  • With this approach the project team can analyze feasibility of different options in terms of cost and energy saving and opt for most feasible options.
  • Predicted energy consumption of the actual building must be less than or equal to the predicted energy consumption of the reference building.

Green Building Certification is a rating tool that helps people assesses the performance of their building against certain nationally acceptable benchmarks. It evaluates the environmental performance of a building holistically over its entire life cycle, thereby providing a definitive standard for what constitutes a ‘green building’.


The Green Rating for Integrated Habitat Assessment (GRIHA) is a methodology created by the TERI and adopted by Ministry of New and Renewable Energy (MNRE) of India as National Rating System of India. It is a green building ‘design evaluation system’, and is suitable for all kinds of buildings in different climatic zones of the country


The Indian Green Building Council (IGBC), part of the Confederation of Indian Industry (CII) was formed in the year 2001.  Consists of different certification protocol for different type of building eg: For residential building – Green Homes, For factory building –  Green Factories etc



Leadership in Energy and Environmental Design (LEED) is one of the most popular green building certification programs used worldwide.[7] Developed by the non-profit U.S. Green Building Council (USGBC) it includes a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods that aims to help building owners and operators be environmentally responsible and use resources efficiently.



BREEAM is the world’s leading sustainability assessment method for masterplanning projects, infrastructure and buildings. It addresses a number of lifecycle stages such as New Construction, Refurbishment and In-Use. Globally there are more than 558,800 BREEAM certified developments, and almost 2,261,300 buildings registered for assessment since it was first launched in 1990.


Traffic studies can take many different forms, but all will generally analyze the existing and future transportation network with a goal of providing solutions for identified issues.  The most common type of study is a Traffic Impact Study, which evaluates the potential impact of proposed developments on the nearby transportation system.  EnerArch Consulting has extensive experience preparing Traffic Impact Studies for all types of developments.

The primary purpose of the study will be to analyse traffic operations to determine if mitigation is necessary.

The diagram shows the tasks necessary to complete the traffic study

Traffic Study Methodology

  • Location analysis
  • External traffic scenario
  • Key junction analysis in vicinity
  • Hourly Traffic volume counts
  • Traffic composition of various vehicles
  • Determination of % of PCU (Passenger Car Unit)
  • Projected Traffic demand assessment
  • Impact on traffic demand from project
  • Level of Service (LOS) & Volume per capacity ratio V/C study
  • Determination of Level of comfort and nature of flow.
  • Internal parking analysis
  • Internal road circulation and traffic movement
  • Recommendation & Mitigation measures



Noise & Sound

Noise/sound is created when the air is mechanically vibrated. The vibration travel through solids, liquids and gases and reaches our ear drum where hearing begins.
The terms noise and sound are often used interchangeably, but the term sound is generally used for communication; whereas the term noise is generally used for unwanted sound.
Building acoustics are mainly concerned with sound vibrations through the air, whereas vibration transmission through solid materials like ducts, concrete, wood etc are equally important when HVAC noise control are considered.

Ambient Noise Quality Standards – CPCB

CPCB’s recommended category wise day and night time noise limits are tabulated below

Noise & Acoustics Study determines the existing & projected noise levels and its impact due to proposed development. It also helps to check noise levels against CPCB’s recommended noise quality standards and if it violates noise standards then mitigation measures are recommended to bring back noise levels to acceptable levels.

“Urban Heat Island” (UHI) refers to the tendency for a city or town to remain warmer than its surroundings, by as much as 10 deg or more. This effect is caused mostly by the lack of vegetation and soil moisture, which would normally use the absorbed sunlight to evaporate water as part of photosynthesis (a process called “evapotranspiration”). This is also the reason why forests are cooler than deserts.

Instead, the sunlight is absorbed by manmade structures — roads, parking lots, and buildings. With little or no water to evaporate, the sunlight’s energy goes into raising the temperature of those surfaces and the air in contact with them. As the day progresses, a dome of warm air forms over the city as convection transports heat from the surface to higher in the atmosphere.

After the sun sets, temperatures remain elevated above the vegetated areas around the city or town, and so the heat island effect persists during the night as well.

As urban areas develop, changes occur in their landscape. Buildings, roads, and other infrastructure replace open land and vegetation. Surfaces that were once permeable and moist become impermeable and dry.  These changes cause urban regions to become warmer than their rural surroundings, forming an “island” of higher temperatures in the landscape.

Heat islands can affect communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness and mortality, and water quality.

Habitat spaces, residential, recreational or institutional areas, pedestrian oriented outdoor spaces, open to sky functional areas and areas which consist of solar energy collectors etc. are areas generally considered as sensitive to the loss of sunlight.

The effects of shading by one building upon another can be either positive or negative depending upon 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. Factors influencing the relative impact of shadow effects are site-specific and include differences in terrain elevation between involved properties, the height and bulk of structures, the time of year, the duration of shading in a day, and the sensitivity of adjacent land uses to loss of sunlight.

The construction of a building inevitably changes the microclimate in its vicinity. Wind speed, wind direction, air flow are all examples of physical aspects that constitute the outdoor climate and that are changed by the presence of the building. The change of these quantities depends on the shape, size and orientation of the building and on the interaction of the building with the surrounding buildings and other obstacles such as trees etc. These changes can be either favourable or unfavourable. Unfavourable changes include increased wind speeds around the building leading to uncomfortable or even dangerous conditions for pedestrians. This is particularly the case at the base of high-rise buildings.
Thus details 3D wind flow analysis using CFD is required to determine projects impact on the micro-climate in the vicinity

The primary aim of indoor air prediction and ventilation analysis is to determine whether sufficient ventilation is provided for all occupants in the building. The intent is to avoid indoor pollutants affecting indoor air quality by providing adequate outdoor air ventilation.

Ventilation performance prediction is to provide the information concerning indoor air parameters in a room or a parking lot it includes impact of both natural and mechanical ventilation strategies.

Ventilation performance can be typically predicted or evaluated by analytical and empirical solutions and computer simulations.

This study would be carried out in accordance with the recommendations of the ASHRAE Standard 62.1-2010 – Ventilation for acceptable indoor air quality, NBC-2005 & Green Homes – IAQ Fresh Air Ventilation.

A typical space gains 30% of its heat through the windows. The successful specification of energy efficient windows requires a sound understanding of the dynamics of thermal performance.

Thus glazing analysis is required to study the effect of glazing on solar heat gain, space conditioning load & Energy consumption & for the selection of optimum glazing system in compliance with ECBC norms.

Sun path refers to the apparent hourly and seasonal motion of the Sun across the sky (and the length of daylight) as the Earth rotates and orbits the Sun. The relative position of the Sun is a major factor in the heat gain of buildings and in the performance of solar energy systems.

Accurate location-specific knowledge of sun path and climatic conditions is essential for economic decisions about solar collector area, orientation, landscaping, summer shading, and the cost-effective use of solar trackers.
