National Conference on <strong>Science</strong> of Climate Change and <strong>Earth</strong>’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’<br />
<strong>12</strong>-<strong>14</strong> <strong>September</strong>, <strong>2011</strong>, <strong>Lucknow</strong><br />
witnessed a grave energy crisis in developing countries during summer season primarily<br />
due to cooling load requirements of the buildings. We can save a lot of energy by<br />
proper designing of the buildings.<br />
Our old architects have set an example of using solar passive concepts in<br />
buildings to fulfill the need of comfort like visual, thermal and acoustic without using<br />
any significant amount of energy. They had used different methods to reduce the<br />
cooling and heating load of houses and buildings in the most sustainable method.<br />
This paper describes solar passive heating and cooling concepts applied by our<br />
ancient architect to Tomb of Aliya Begam, <strong>Lucknow</strong> which is an Awadh architectural<br />
building. They used passive concept like dome roof, high roof and thick wall, octagonal<br />
shape of building to meet the needs of heating, cooling and natural lighting. The paper<br />
describes the results obtained on several parameters like U- value, R- value, time lag,<br />
decremental factor and day light factor concerning heating, cooling and natural lighting.<br />
The buildings which are designed with sustainable features like Tomb of Aliya Begam<br />
are advocated to reduce the comsumption of energy in buildings.<br />

Solar photovoltaic modules are generally characterized in simulated conditions.<br />
On actual sites the performance of the modules may vary. An effort has been made to<br />
measure the performance of solar photovoltaic modules in different months at particular<br />
location i.e. <strong>Lucknow</strong> with respect to temperatures for the different seasons for a year.<br />
In this paper, data is presented for months of May, June, July and August.<br />
With the given data, an equation has been developed mathematically which is in<br />
good correlation with the measured data. It is helpful in developing a relation of the<br />
efficiency of modules with corresponding ambient temperatures.<br />
In this paper, only one climatic parameter has been considered i.e. ambient<br />
temperature, while considering all major parameters like temperature, humidity, wind<br />
velocity, cloud cover, dust etc, a standard equation can be developed which would be<br />
helpful in having a relation of all major climatic parameters with the performance of<br />
solar photovoltaic modules and the level of accuracy of proposing the efficiency of<br />
modules would increase while increasing the number of climatic parameters.<br />
