PROJECT DEVELOPMENT AND SERVICES 7.7 Program & Management (continued) 3. Sustainability Appropriate Management of Sustainability Achieving Energy Efficiency across all of the services is a critical challenge when it comes to refurbishing old building, as old or minor inefficiencies can result in substantial costs in both maintenance and ongoing expense. A cost benefit analysis would need to be undertaken by the engineers to determine which equipment would achieve the greatest efficiencies and associated savings. However, the leasing team will benefit from this increased amenity through greater rents with tenants looking for increased amenities associated with : • Air • Water • Light • Fitness Comfort • Mind and Innovation Engineering Restricted Plant Space When redeveloping aging assets, Waterman have found that assets were often built into plant rooms, with no proposed replacement strategy. To resolve this Waterman have worked closely with chiller manufacturers who have developed methods of disassembling large pieces of equipment, into smaller components, which can be carried up flights of stairs and brought into small lifts. This has eliminated the need for expensive crane lifts, wall removal and other costly builders works. Improved Energy Targets With sustainability such a central focus of the building industry, when buildings are redeveloped, the expectation is that the energy use of the building can be improved. To this end Waterman have investigated and designed more efficient mechanical solutions such as chilled beams to replace existing variable air volume systems. This has allowed to increase the NABERS energy rating from 4 to 5 stars. Further replacement of chillers with high efficiency variable capacity machines and replacements to LED lighting there are substantial ongoing savings to be made. 56
