Abstract The results of the building optimisation presented in this article come from the author’s entry project in the Design Optimisation Competition 2014. Simulations were conducted to help to design an office building and to minimise its costs and impact on the environment. Ultimately, the building’s construction costs were reduced to £2,294,216 and annual CO2 production to 136,169.3 kg, while maintaining discomfort hours below 200 hours per year and daylight floor area above threshold on the level of 60.0 %.

Construction cost is a major concern to both clients and contractors. Based on a hypotheticalconstruction project (a six-storey concrete framed office building), cost and otherrelated information was collected through a survey of contractors in Japan, the UK and theUS. Using multiple regression analysis it was found that lower overheads, less prefabricatedcomponents, and fewer design variations could reduce construction cost. Overheadslargely represent indirect costs to contractors and if reduced can lead to increased profitlevels and improved competitiveness. The use of prefabricated components may be problematicwhere there are delays in production, insufficient coordination between design andconstruction, and congested transportation on site. Design variations during constructionbring about uncertainties and are disruptive to the construction process. These factorshave paramount impact on construction cost and demand close attention and consideration.Contractors are advised to reduce the costs of their overheads and utilise prefabricationappropriately, while clients and designers should minimise the number of designvariations during construction if better cost performance is desired.

The design of the glass skylight of the courtyard in an office building is introduced in the paper. One-way stability of the cross bar in the cable system is analyzed. The support system designed by the new style, reasonable force, to meet the requirements of normal use, the surrounding concrete support structures of smaller, saving construction costs, so that the top economic and practical lighting. By Midas-based stress analysis software, the cross-bar system, a number of capacity factor and to strengthen measures were discussed, which can be a useful reference for similar projects.

With the commencement of the integration construction of urban and rural areas, Chinese rural structural adjustment is occurring. The government behaviors about merging townships bring a large number of vacant administrative office buildings. This paper aims to study the possibility and rationality about the administrative office building reuse in this context. How to renovate depends on the original building space characteristics and the new space requirements. The construction method includes the repair, replacement and increase. Finally, the example that the administrative office building transformed into the disabled care center in the Luonan County proves the possibility and rationality about the renewal patterns. This kind of renewal patterns will save construction costs, bring economic benefits and a good social effect.

A fire involving an electric service transformer and its cooling fluid, a mixture of PCBs and chlorinated benzenes, contaminated an office building with a fine soot. Chemical analysis showed PCDDs and PCDFs including the highly toxic tetra isomers. Guinea pigs were chosen as an experimental animal to test the soot's toxicity because of their sensitivity to these compounds, and the liver was examined because it is a target organ. The soot was suspended in 0.75% methyl cellulose and administered in a single dose by gavage at levels of 1,10,100, and 500mgm soot/kgm body weight. Each dose group was composed of 6 males and 6 females. Control groups included 12 (6 male, 6 female) animals fed activated carbon in methyl cellulose, 6 males fed methyl cellulose, and 16 males and 10 females untreated. The guinea pigs were sacrificed at 42 days by suffocation in CO2. Liver samples were immediately immersed and minced in 2% gluteraldehyde in cacadylate buffer at pH 7.4 and 4°C. After overnight fixation, samples were postfixed in 1% OsO4 in cacodylate for 1 hr at room temperature, embedded in epon, sectioned and stained with uranyl acetate and lead citrate.
