Abstract-The primary function of a building is to provide thermally comfortable environment to its occupants. A good indoor climate is important for the success of any building, not only because it will make its occupants comfortable, but also because it will decide its energy consumption, and thus influences its sustainability. A literature review of over 100 research papers, in four areas in the field of Energy Conservation in Buildings, i.e. (i) Climate Responsive Buildings, (ii) Analysis, Simulation and Modelling, (iii) Zero Energy Buildings and (iv) Thermal Comfort, were conducted in order to obtain a valid research topic. The findings of the literature survey is presented in this paper which include issue wise discussion, solution approaches used by various researchers, strengths, weaknesses and future scope of work in the four issues pertaining to energy conservation in buildings. Out of the several identified lag, it was felt that there was a dearth of field studies based thermal comfort research in India, which is essential for the correct definition of building codes. Proper building codes are required not only for providing comfort condition but also to conserve energy. Hence field studies based thermal comfort study was considered for further research study. Thus, this paper summarizes the researches about Climate Responsive Buildings, Analysis, Simulation and Modelling, Zero Energy Buildings and Thermal Comfort. It also concludes the methodology of these researches in above four fields, and gives further work suggestions.

“…The most of researches related to the problems of thermal comfort testing refer to savings that can be achieved during the operation of AC system, in order to reduce fuel and electric energy consumption, i.e., to achieve more autonomy in vehicle movement [6][7][8][9][10]. The use of air conditioning system not only considerably improves the comfort during driving, but it also reduces the internal noise and the need for additional opening of the window.…”

The paper presents the integrated application of two methods during testing HVAC system efficiency in the cabins of HUMMER ?1151A1 and OAR 1RL-128D off-road vehicles. Spatial measurements of change in air temperature per time have been performed at three vertical levels (head, knees and feet) of the driver and passengers, which totals to 15 measuring points per vehicle. The main goal of testing was to evaluate accurately the efficiency of heating and cooling in relation to time interval required to attain a designed temperature of comfort in the vehicle cabin, on condition that the difference in ambient temperature levels does not exceed 10?C. With a view to more efficient evaluation of thermal comfort in vehicle cabins, the testing was performed also of Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD) indices. Standard thermal comfort surveys ask subjects about their thermal sensation on a seven-point scale from cold (-3) to hot (+3). This research is carried out according to the methods based on ISO 7730, ASHRAE 55 and SORS 8419 standards.

“…Lower air temperatures in the vehicle cabin are possible, however, the comfort of the passengers is preserverd or even increased [6]. In the comfort chart in figure 1 it can be seen that with a radiation heating and hence higher surface temperatures of the adjacent walls, a lower air temperature is needed to create a comfortable environment for the passenger.…”

In full electric vehicles, the energy for heating the passenger compartment has to be taken, contrary to conventional vehicles, from other sources than the waste heat from the internal combustion engine. If the energy is taken from the traction battery, the driving range of the vehicle can in the worst case be reduced by up to 50 %. Other heating concepts require complex additional heating equipment and sometimes even storage tanks and can increase the weight of the vehicle significantly. The topic of this paper is to describe a system of heating up the vehicle interior with reduced energy consumption by using a special heating coating, which can be attached to any carrier material in a vehicle cabin. This coating emits infrared radiation, which is commonly reckoned as very comfortable and an energy efficient alternative to conventional heating concepts.Index Terms-full electric vehicle, infrared heating, energy consumption, thermal comfort, thermal simulation, measurement 978-1-4799-6782-7/14/$31.00 ©2014 IEEE
