Assessment of Daylighting Design Tools Against Test Cases Included in CIE's 171:2006 Report Frantisek Vajkay1,a*, Lukas Zizka2,b 1Brno University of Technology, Faculty of Civil Engineering, Institute of Building Structures, Veveri 95, 602 00 Brno, Czech Republic 2Brno University of Technology, Faculty of Civil Engineering, Institute of Building Structures, Veveri 95, 602 00 Brno, Czech Republic avajkay.f@fce.vutbr.cz, bzizka.l@fce.vutbr.cz Keywords: Daylighting, daylight factor, working plane, CIE sky types, CIE test cases, computer simulations, ray-tracing, RADIANCE, Daniljuk’s approach.
Albeit, an engineer uses a certain daylighting design tools he does not have to know anything about its accuracy, i.e. the precision and errata of obtained daylight factor levels over the reference plane of an indoor or outdoor space.
Daniljuk's approach is widely known by the engineering community.
Conclusions It can be stated that both of the assessed approaches do perform quite well when taking a deeper look at the results, hence each of them can be recommended for daylighting design of buildings in engineering practice.

Risk Analysis and Management for the Collapses of Tunnel Yue Lei a, Xiong Zeng b and Fang Huangc School of Civil Engineering and Architecture, Central South University, Changsha, Hunan,China aLeiyue8210@163.com bZenxwa@163.com，cDoccee@126.com Keywords: risk management; collapses of tunnel; numerical method; analytical method Abstract：The evaluation of the correct stability factor of tunnel is a critical element in the various design and construction phases of a tunnel excavated in difficult geotechnical conditions.
Introduction Because of engineering geologic condition, hydro geological condition and artificial factor, it is easy to result in collapse of tunnel, which can result in enormous casualties and huge economic losses in mountainous regions.
Strong and urgent social demand for the release of traffic congestion urged decision makers to hurry, which in turns engineers and construction workers involved in the project urged to hurry.
The over-demand and insufficient time affected normal civil engineering process considerably.

So the formula that suggested is much close to experiment, and its calculated result for Q460 high strength angle connected by single limb is in the safe side, which can be used for the engineering design.
