The Outcomes
Reduced Number of Lifts Based on conventional design and analysis, the optimum solution from a purely vertical transportation perspective was 10 passenger lifts. This was based on a blanket analysis regarding population density and where all floors were assumed to be the same. By analysing each floor and obtaining stakeholder input, the actual needs and floor areas were determined in more detail than the blanket approach allowed. This comprehensive approach allowed D2E International to run extensive simulations based on accurate information. The result of this detailed approach was that the number of passenger lifts could be reduced to 8 whilst still maintaining high levels of performance in terms of waiting time and handling capacity.
Reduced Design Rise The building was being designed on a speculative basis and so the design had to allow for the varied requirements of any possible tenants. For example, tenants who required a certain number of floors, dealers whose population density requirements are higher than that of a conventional office, impact of changing the location of transfer floors for the low and high rise group of lifts. This detailed and comprehensive approach to the vertical transportation requirements allowed the client’s design team to quickly plan lots of options, with reduced risk, regarding future occupational requirements of the building.
Latest Technology The design of the vertical transportation encompassed the latest technology in terms of passenger interfacing with the lifts and the building. By using destination control systems (interestingly not used in the traffic calculations) as promoted by the major lift companies, not only were up peak calculations enhanced whilst still coping with two way traffic at lunchtime, the level of interfacing provided by these systems allowed for greater personalization of lift use and greater security, for not only entry into the building, but between floors.
