As a public building, the Campus 1 of UPGRIS requires to comply with the accessibility for all (including the diffabled people). Yet, the current condition causes the diffable people unable to access the facilities of the building, which means they are not capable of doing their activities on their own. How should we determine the condition? and how should be advise to retrofit?. The purpose of this reasearch is to identify and analyse the need of diffabled people facilities in campus 1 UPGRIS which have multiple factor. Qualitative and quantitative methods are used in the process of analyzing the problem through comparative analysis according to the regulation, hereinafter a scoring analysis will be held quantitatively to determine the priority of the problem. Commonly the dimension of the doors which width less than 80 cm, so the wheelchair can't go through the room. The conclusion for all building, is not prepared well for the diffable people acting independently.

Semarang city in Central Java has natural lighting from sunlight, throughout the year and can be optimized when integrated with artificial lighting. It will be reduce electrical consumption. Research in lecturer’s workspace in Gedung Pusat UPGRIS performs a simulation analysis of natural and artificial lighting and their integration using the Dialux EVO version 9.0. The simulation results of the existing condition of natural lighting is 164 Lux (09.00 AM) and 225 Lux (01.00 PM), while the existing simulation results provide 201 Lux with a power consumption of 1.69 Watt/m2. The results of the integration natural and artificial lighting produce 265 Lux (09.00 AM) and 256 Lux (01.00 PM) with the same electrical consumption of 0.84 Watt / m2. This value shows that the existing simulations of natural, artificial and integrated of them are still less than the SNI 16-7062-2004 standard is 350 Lux. The first retrofitting by changing the type and number of lamps resulted in 393 Lux higher from SNI standard 350 Lux. The simulation produced 556 Lux at 09:00AM and 648 Lux at 01:00PM, veryhigher than SNI standart 350 Lux. Through this retrofitting approach, artificial lighting at night shows minimum standard because no light. The second retrofitting effort is to turn off the lights automatically Lux sensor in the workspace area near the windows the natural lighting is strong enough, the results show that the illumination strength of 402 Lux at 09:00AM and 494 Lux at 01:00PM with low electrical consumption during the day becomes 2.92 Watt/m2.

The window as the opening of natural lighting is more critical to conserve building energy, but if the size opening is too broad will increase the solar heat into the room. Over of heat, will also cause discomfort in the place because the value of OTTV (overall thermal transfer value) will also increase. The purpose of this study is to identify components, calculate the OTTV value and the analysis of shadow of the sun into the room. In the meeting room of the UPGRIS postgraduate building, there is too many windows that make the room glare and hot. It is felt to affect inefficient artificial energy (Air Conditioning). The method used is a type of quantitative research with an experimental approach. The results of the OTTV study in this room is 52.33 watts/m2, and this is exceeded from SNI (35 watts/m2). This research redesign of windows and shading to comply with maximum standard.

This research evaluated the building accessibility for disabilities people. Gedung Pusat (GP) UPGRIS, as a once of a public building, is required to comply with the availability for all (include for diffabled people). The current condition causes they are unable to access the facilities of the educational building, which means the student with disability not capable of doing their activities on their own. There are many problems: the doors which width too small, the opening doors direction were false, vertical access was not accessible, lavatory not adapted for disabled, and any other. The objective of this research to evaluate and build a concept redesign for diffabled people's facilities. The architectural design analysis use in the process of restructuring the existing facilities. The solution choices, according to a minimalising budget and less of destruction.
