A legal framework for the integration of environmental, social and governance issues into institutional investment (1 MB | 154 pages)

The temperature probe will then open the PTR valve and discharge hot water to the drain waste line. It is recommended that an ECV be fitted to the cold water supply line. This will relieve cold water, not hot water, during the heating cycle, saving energy and increasing the life of the PTR. Some local governments make it mandatory to install an ECV in the cold water line. PTR and ECV valves are safety valves and should be replaced every 5 years or as the tank manufacturer states.

The UNEP FI Asset Management Working Group (AMWG) invited Freshfields Bruckhaus Deringer, one of the world’s largest law firms, to consider whether institutional investors such as pension funds and insurance companies are legally permitted to integrate environmental, social and governance issues into their investment decision-making and ownership practices. The AMWG further asked how the law might be expected to evolve in this area. The study describes the legal framework for institutions in Australia, Canada, France, Germany, Italy, Japan, Spain, the UK and the US. Published: 2005 | by: Freshfields Bruckhaus Deringer

The Pressure and Temperature Relief valve (PTR) is designed to relieve the increase in pressure caused by water expansion during the normal heating cycle on a hot water service. The valve will then relieve the increased pressure by releasing drips of hot water to the drain line, Should the temperature thermostat fail and not operate correctly the water will overheat.
