Our Story

Energy Shrink envisions a world where human ingenuity is deployed towards meeting the basic human needs for shelter and thermal comfort without destroying the natural eco-system it depends on; where the path of economic progress is paved with an eye on sustaining the environment for future generations. The mission of Energy Shrink is to help realize this vision by facilitating the market adoption of energy efficiency in the buildings sector; to bridge the space between the body of knowledge pertaining to green buildings on one side and the decision makers on the other. The end goal is lesser waste, greater economy, better health, and greater sustainability in the buildings sector.

Shattering Glass Myths: Design for Climate Action (2016)

This article published in the sustainable business blog Triple Pundit discusses five myths surrounding glass skins that explain why this is cause for concern. The first opportunity to reduce energy use in buildings lies in the building skin, which can impact the total energy use of a building by 10 to 50 percent. And yet we continue to see buildings being encased in glass.  Full article

ACEEE Summer Study: Energy Efficiency in the Forward Capacity Market: Evaluating the business case for building energy efficiency as a resource for the electric grid (2012)

Authors: Joel Fetter, Smita Chandra Thomas, Andres Potes, Gary Rahl

Two regional electricity grid operators – Independent System Operator-New England (ISO-NE) and PJM Interconnection Regional Transmission Organization (PJM) – use Forward Capacity Markets (FCMs) to induce the construction and maintenance of resources needed to satisfy future electricity demand. Increasingly, the meaning of ‘capacity’ has expanded from traditional wires-and-generators solutions to include greater levels of customer-sited resources, including energy efficiency. As with conventional merchant generators, the success of FCM rests on whether it can send price signals to end-users powerful enough to mobilize investments in energy efficiency activities that otherwise would not take place. This paper uses a cash flow analysis to assess the revenue opportunities that these markets offer to owners and operators of commercial buildings. The analysis investigates whether the costs and revenues associated with supplying energy efficiency capacity in the newest EE FCM, operated by PJM, are likely to support a compelling value proposition for large commercial buildings. The results show that the overall revenues an owner or operator might expect increase only slightly. It finds that the market players best positioned to compete in it are those that are able to aggregate large portfolios of efficiency measures which can be bid into the market in a cost-efficient manner.

Master’s Thesis: Passive Strategies for Residential Construction in New Delhi (1999)

The thesis explores passive climate-responsive design strategies for a typical residence in New Delhi, India to minimize the use of electricity. Energy-10 software was used a tool to quantify the energy savings. Strategies included non-conventional building materials, optimal layout and window sizing and placement, and whole-house fan among others. (Contact us for more information)

B.Arch. Thesis: Sustainable Rehabilitation of Wildflower Hall, Shimla, India (1994)

Wildflower Hall was a historic hotel in the Himalayan region near Shimla, a favorite retreat of Presidents and senior officials, which burned to the ground in 1993. At the time of writing the design thesis, the site was being considered for development as a 5-star hotel. The thesis explored options to redevelop the site sustainably — using traditional climate-responsive building techniques and incorporating the use of the site to include areas for local vendors to work and live on site, adding a vibrant, traditional living experience for hotel guests.
