Sustainability

Interserve is dedicated to providing a sustainable business for our customers, employees, communities and shareholders. We have developed RENEWABLES as a framework for identifying and managing 10 sustainability areas that address the social, economic and environmental aspects of our activities. This helps us to discharge our responsibilities, improve on our performance and bring added value to our clients.

Sustainability in practice

• Incorporating a Passive Stack ventilation system on the St Helen's rehabilitation wards has achieved annual operational costs savings of approximately £8,000 for the Trust, with the system saving 64 tonnes of CO₂ each year.
• The BREEAM-excellent Malvern Community Hospital made use of combined heat and power (CHP), reversible ground source heat pumps and photovoltaics to achieve a predicted saving of 89 tonnes of CO₂ per annum.
• State-of-the-art Active Chilled Beam Technology was incorporated into the St Charles Community Hospital Renal Unit, providing significant cooling to the ward. The beams reduce installation time, save energy and reduce maintenance thereby dramatically cutting the whole life cost of an air conditioning system.
• We are supporting University College London Hospital NHS Foundation Trust, who is participating in the Carbon Management Implementation Plan (CMIP), to reduce annual carbon emissions by 15 per cent by 2010. Our systematic carbon footprint analysis, structured action plans and a series of workshops, are expected to reduce carbon emissions and energy costs for the UCLH Estate.
• Use of ground source heat pumps, mixed mode ventilation, increased thermal insulation and reduced air permeability is expected to save the Trust at Moseley Hall Older Peoples Unit 85 tonnes of CO₂ per annum with a 22 year payback.
• Enzyme-based urinal cubes allow a waterless urinal without the usual capital investment. Their use has lead to an annual water saving of over £9,000 and a carbon saving of 3,185kg per annum, based on a single site of 50 urinals.
• Effective dosing control systems for cleaning products coupled with the use of organic-based cleaning systems are reducing waste and chemical pollution. The products have lower COSHH ratings meaning they are safer and simpler to use and store and there is no added pollutant to the waste-water stream.
