• Optimization of energy consumption of apartment by applying self-sufficient energy strategies.

Contribute to the implementation of the highest carbon emission and carbon neutrality in Sri Lanka. The contrast between the rising energy consumption of residential buildings in Sri Lanka and higher energy efficiency targets, this report shows that the constitution of energy consumption residences throughout their life cycle and then subtract the overall energy performance strategies. Main part of building energy consumption involves materializing and using energy, which will both be continually increasing, and divided into energy utilization and waste. By bringing about the energy consumption in the use phase, the energy consumption of residences can be further categorized into energy consumption of indoor spaces, housing behavior and public facilities, where the internal factor of continuous increase are all worked out. This research constructs on the analysis of the causes of energy wastage model of energy consumption in residential buildings shows that the key to energy efficiency in residential buildings lies in scientific decision-making, lifestyle improvement and adequacy Introduction of energy efficiency technologies and measures and points to the promotion of buildings energy towards Efficiency throughout the life cycle of buildings and construction activities is required to achieve CO2 Compliance and carbon neutrality.

Automatic Fan Speed Control with Temperature and Humidity

Human comfort, productivity, and a sense of health and well-being are the positive outcome of a healthy indoor environment where the indoor air is fresh and free from doors, dust and other contaminants. Human comfort depends on a complex interaction of multiple variables with humidity being only one of them. However, optimizing both temperature and relative humidity satisfies the comfort requirements for a wider variety of occupants as opposed to regulating temperature only. Low relative humidity in indoor air results in human discomfort. Headache, irritated eyes, sore throat, and dry skin are all symptoms of a dry indoor environment. Dry air lowers the natural defense against airborne infections and makes people vulnerable to the attack of viruses and other micro-organisms. In addition to the problems associated with low humidity, too high humidity can also cause problems. These problems are related to the growth and spread of unhealthy biological pollutants and to the damaging effect of moisture on the construction materials. Typically humans are less sensitive to humidity than temperature. People generally fail to associate discomfort and potential health problems with variations in relative humidity. This is where a good technology can support the human senses. A reliable humidity measurement is the key to successful humidity control. There is no one temperature and humidity condition at which everyone is comfortable. People are comfortable at a range of temperatures and humilities. Research conducted over many years on large numbers of people by the American Society of Heating, Refrigeration, and Air Conditioning Engineers concluded there is a range of combined temperatures and humilities that provides comfort to most people. Notice that most people are comfortable at higher temperatures if there is a lower humidity. As the temperature drops, higher humidity levels are still within the comfort zone. This makes sense if you think about your own experience. Remember being in a hot, dry, desert-like environment and being surprised at how you didn't feel hot? Or being in a humid place where the temperature wasn't that high, but you felt like you were melting? That's the effect of humidity and temperature on human comfort.
