What is a charrette
Description: 

One of the key objectives of the Indo-Swiss Building Energy Efficiency Project is to help Indian builders and developers in adopting new processes, tools and technologies for designing energy-efficient buildings. BEEP believes that cost effective energy efficient design is possible by following an integrated design process and a “charrette” or an intensive design workshop is an effective tool to implement the integrated design process. Integrated Design means that the client, the architect and the engineering design team start working on the project together right from the beginning, based on the client brief. Doing this allows to tap the largest energy saving potential with minimum effort and cost.

BEEP Integrated Design Charrettes are conducted over 4 days by a team of senior Swiss and Indian architects and engineers, for selected building projects in their early design stage. The objective of these charrettes is to develop a viable energy concept for the building project.

Till date BEEP has conducted charrettes for 11 commercial projects. The potential for energy savings as a result of BEEP initiatives were in the range of 25% to 50%.

Technical Assistance

Selected projects would be assigned a BEEP expert team, consisting of three to four Swiss and Indian experts (architect, building energy expert, HVAC [heating, ventilation, and air-conditioning] expert, etc). The technical assistance from the team would be available in three steps as described below:

Step 1 Preliminary analysis: Based on the concept design description, data, and drawings provided by the building project, the BEEP expert team will prepare a basic energy simulation model of a part of the project to analyze energy-efficiency options and define the baseline energy performance.

Step 2 Integrated design charrette/design work shop: The BEEP expert team would organize a design charrette (design workshop) of two to three days’ duration at the premises of the builder/developer. The participants in the charrette would be the builder/developer management team, the project design team, and the BEEP expert team. The project design team should include at least the client, the architect, and the HVAC/Mechanical, Electrical & Plumbing MEP consultant. Through a structured collaborative process and effective use of energy simulation tools, the charrette would come out with recommendations for an energy-efficient design. The recommendations would cover master planning, building massing, envelope solutions, energy supply, daylight, bioclimatic features, and advanced HVAC system design.

Step 3 Post-charrette support: After the charrette, the BEEP expert team will continue to provide technical assistance to the design team until the schematic design is finalized (typically for a period of 6 months). The BEEP expert team will carry out additional simulation studies while integrating the revised project design features.

The post-charrette technical support by BEEP will also include two meetings:

  • One meeting will be held before finalization of the schematic design. The objective of this meeting is to provide specific design inputs to the selected building project by the expert team.
  • A second meeting, a wrap-up workshop, will be held after the finalization of the design. The objective of this workshop is to validate the final design, and to assess the savings achieved. In addition, an interactive evaluation session will be organized to assess the impact of the charrette, and draw lessons for future charrettes.

For these exchanges, modern communication tools such as video conferencing and other online collaborative tools will be used. The Swiss experts are not expected to attend post-charrette meetings or workshops physically.

BEEP will bear all the costs of the BEEP expert team, which includes their professional fee, travel, boarding, and lodging expenses.

The BEEP team would also carry out follow-up activities to monitor the application of the charrette recommendations in the project at regular intervals.
