Technology Adoption Project (TAP)

PREMISE

The project aims to substantially modify the design blueprint of commercial building structures owned by corporate entities or leased-out by commercial developers to embed sustainable cooling at the core of the design DNA through integration of passive thermal comfort design and sustainable cooling technologies. It seeks to formally integrate sustainable cooling as a core policy element in corporate real estate procurement/design decision making at the management level so that all future structures built by the same corporate, and their peers, reflect a similar sustainable-cooling integrated building design. The TAP budget has provisioned to engage 64 distinct influential corporate entities and seeks to eventually lead to upward translation of learnings and recommendations for integrating sustainable cooling into urban planning policy through engagement with high-level personnel in the administrative machinery of India’s executive branch of government.

Technologies Adopted

The HVAC-system energy audit leads to a Technical Feasibility Report that outlines the energy/cost/GHG emissions reduction from implementation of one or more of the following:

R290 split-unit ACs

R290 refrigerant gas uptake for ACs & centrally-cooled buildings: R290 split-unit ACs are not only far more energy-efficient (20% more compared to conventional split-unit ACs), but lead to lower GHG emissions from fluorinated refrigerant leakage.

Direct/Indirect Evaporative Cooling

Direct/Indirect Evaporative Cooling uptake: The lowest annual energy consumption and GHG emissions per unit area of cooled space in hot and dry regions is achieved through the use of direct as well as two-stage (direct/indirect) evaporative cooling when compared to the business-as-usual options of unit ACs or central AC systems.

Passive (Structure) and Active Radiant Cooling

In this technology, naturally cooled water (from a ground or surface water source) is circulated through ceilings or floors by means of a simple plumbing system consisting of pipes & channels.

Solar Vapour Absorption Machines

Vapour Absorption chillier machines (VAM) produce chilled water using a solar source rather than electrical input as in the case of vapour compression cycle.

Passive Cooling Technologies

Besides the above active (machine) cooling technologies, the project will also promote passive cooling technologies and design approaches in buildings. The more prominent amongst these are: Roof and Wall-Insulation, Radiant Barriers / Night-Sky Radiation Systems that shield roofs from solar radiation during the daytime and promote rapid heat dissipation through radiation at night using retractable low-emissivity radiant barriers and high-emissivity roof coatings, Efficient Fenestration Systems such as Engineered Glazing and Double-Glazed Units, Shading Devices, and Spectrally Selective Window Films.

We offer free HVAC-system energy audits to office buildings, banks, hotels and builders.

The project aims to embed sustainable cooling in the design blueprint of commercial building structures through the integration of passive thermal comfort design and sustainable cooling technologies.

REQUEST A FREE HVAC-SYSTEM ENERGY AUDIT

To conduct this audit we need to receive 3D drawings of the building.
