A passive solar house was constructed in Alice, South Africa as a prototype for low-cost energy-efficient housing. Minimum air exchange rate was adopted to minimise heat transfer between the inner and ambient environment of the house. The aim of this study is to investigate the air exchange rate and sensible air heat transfer in a passive solar house. The tracer gas technique was used where CO2 was consecutively injected into the various zones of the house. The CO2 concentration was measured using a Non-Dispersion Infrared gas sensor, and the air change rate (ACH) in each zone was evaluated via the CO2 decay rate. Auxiliary parameters were also monitored, such as indoor air temperature, ambient air temperature, wind speed and direction. Zone 1 had the maximum ACH of 2.27 h−1 with all ventilation components open. The corresponding sensible air heat transfer was 275.59 W. With all ventilation components closed, the whole house’s ACH was found to be within the recommended domestic level. The windows were also found to have a significant impact on the ACH, resulting in a daily cumulative heat loss of 0.196 kWh/m2. Hence, proper operation of windows is recommended to minimise indoor thermal load without compromising comfort.

Weather monitoring and forecasting system plays an important role nowadays in all the aspect of science, trade and other fields not limited to the field of cultivation, farming, fishery, naval trade, shipping, military operations, air navigation etc. Wind speed and wind direction is one of the most vital weather variables like moisture, pressure, temperature, density, rain forecast, solar radiation, clouds, air masses, fronts and storms. In this paper, a low cost PIC16F887 microcontroller based portable wind speed and wind direction monitoring system called an anemometer is designed & experimented. The designed anemometer is divided into two parts namely mechanical and electrical parts. Both parts are developed, designed and tested in this research work. Wind turns the cup of Anemometer and produced mechanical energy that converted to electrical energy or signal. The electrical signal or pulse intervals determine by the microcontroller and generate consequence pulses to find out the wind speed. The programming codes inside the microcontroller helps to extract the voltage drops measured from a potentiometer connected to the mechanical part of Anemometer and intellect the wind direction precisely. A lucrative 16x2 liquid crystal display (LCD) is used to display the wind speed and direction.
