SUSTAINABILITY


procurement, use and end of life practices. Environmental issues include product design and raw materials, energy consumption, airborne emissions, water consumption and effluent, transportation impacts and end of life/disposal impacts. AAMI is currently considering an update to this document and user comments would be helpful. Another emerging effort is a wiki solution, which is similar to that of I2SL for laboratory equipment. Mazzetti+GBA seeks to create transparency for medical equipment energy consumption by using the ASHRAE imaging protocol to collect and disseminate actual consumption data to assist building designers in the right sizing of building equipment, especially at higher levels of the system that serve a larger number of devices. Users and engineers are encouraged to contribute data to this effort. Together we need to acquire better data from manufacturers, contribute to tracking and share actual usage data and make more efficient equipment choices while still demanding exceptional patient outcomes. When Stanford University needed help


with sustainable medical equipment, there was none. Now there is, and more is on the way. To help ASHE with its project and AAMI with its new standard, please share your data with Mazzetti+GBA. IFHE


Health in the Green Economy


The problem discussed is especially acute for health facilities in the developing world, where energy can be intermittent and expensive. The World Health Organization sought to address this issue in an unpublished guidance document entitled Health in the Green Economy. This document recognised the particular problem created by energy consumption of medical equipment designed for the developed world. There facilities tend to use much less energy overall, compared to similar facilities in higher resourced countries. Thus, a piece of medical equipment will have, as a percentage, a much higher impact on operating costs when compared to other countries that are higher resourced. The document also recognises the ‘reverse innovation’ movement, in which products developed specifically for low resourced facilities could also benefit high resourced facilities in other parts of the world by offering exemplars of low energy, but highly effective equipment. The WHO recognised the need to promote the creation and diffusion of this type of technology and has continued to support this kind of initiative.
