This paper gives a pictorial view of the relevance of lean thinking, particularly the applicationof muda as a supplement to the sustainable improvement diagnosis technique of existing public office buildings,for a fuller assessment of users’ requirement in Nigeria. The impact of perceived muda was related to the triplebottom line of sustainable development on perceived job productivity and desi...

This paper provides the first systematic analysis of the choice by organizations to occupy green office space. We develop a framework of ecological responsiveness, and we formulate five propositions to explain why specific firms and industries may be more likely to lease green space. We test these propositions by analyzing the decisions of more than 11,000 tenants to choose office space in gree...

We envision future office buildings that partly or fully implement a flexible office organization, i.e. office space is assigned dynamically on request. These organizational principles save office space, but require a sophisticated software system that is highly dynamic, scalable, context-aware and self-organizing by means of selfconfiguration, self-optimization and self-healing. We propose an ...

This paper studies the impact of surrounding buildings on path loss and multipath delay spread for Personal Communication Services (PCS) operating inside of buildings. Measurements conducted inside three large office buildings in the San Francisco Bay area provide an extensive database for propagation models at 915 MHz and 1900 Wlz, and show variability in path loss and delay spread caused by m...

The paper applies a computer-based method involving stochastic search, multi-criteria optimization and color filtering to investigate the tradeoff between the life-cycle profitability of highrise commercial office buildings and their load-path safety against progressive collapse under abnormal loading. The study was motivated by the progressive-collapse failure of the twin towers of the World T...

This paper describes the development and operation of a dual-band time~domain radar system used to measure indoor multipath propagation characteristics in several office buildings and factories. The system operates at 1.3 GHz and 4.0 GHz, and uses 4 ns rms pulses to provide estimates of indoor radio channel impulse responses. The effects of ante.nna diversity, .frequency scaling, and topography...
