Since incorporation Stirling Consulting has provided engineered solutions within the Building Services Sector to meet client enquiries for underperforming systems. Experience has confirmed that a lack of identifiable structure can contribute to failures from the design/procurement process- a factor more common in the current environment where contractor and client assume greater responsibility within the project. To mitigate this potential we have developed an ISO 9001 Quality System which will be supported by ISO 14001 by Jan 2011. Following increased client demand we have devised a procedure we identify as Single Point Accountability [SPA] in which our submissions are supported with a full complement of installation/reactive and planned maintenance programs throughout the UK. This provides significant savings, over the more traditional concept of an extended site team, and reduced project lead/duration times. Energy Performance Certificates [EPC's], Display Energy Certificates [DEC's], Standard Assessment Procedure [SAP's] & Air Conditioning Inspections are provided to ensure compliance with the Energy Performance of Building Regulations. Along with a complement of professional memberships we maintain our compliance with F-Gas/Ozone Depleting Regulations & Environmental Protection Act in recognition of our status as specialists within the refrigeration & air-conditioning fields. The latest progression of the designation being the appointment as a distributor for JIMO refrigeration equipment [www.jimo.pt] Renewable solutions are here to stay, the process naturally being supported by us, but their adoption must be particularly considered when applied in remedial applications and in particular the interpretation of factory supplied data against geographic climatic conditions. With this in mind we have, should a request be received, produced a guide detailing site observations on Ground Source & Air to Water Heat Pumps which is available in electronic format.
