Design Strategy Of Air-Conditioning For A Residential Building
Questions: Does the existing HVAC system or other cooling system have the capability to match with the cooling requirement of the occupants? Does the design strategy being adapted by the building is efficient in terms of energy consumption? What are the benefits of determining suitable air conditioning strategy for residential buildings? Answers: Introduction This research is based on determining the design strategy of air conditioning for a residential building. The focus of this research is to identify gaps in the previous studies available on the topic or the same research area. The air conditioning system in a building is responsible for around 50% of the energy being consumed and other 50% is consumed by other services in the building. Hence, it is essential to determine effective design strategies for air conditioning in a building. The reduction in energy being consumed by air conditioning will help to increase savings on consumption along with carbon emissions (Grondzik and Kwok 2014). In this study, the proposal for conducting research on design strategy for air conditioning in a residential building has been prepared to discuss on motivation behind the research. Further, a timeframe has also been prepared to illustrate upon finance activities along with duration required to complete the research project. Background of the study This study is based on identifying the effective design strategies for implementation of air conditioning to suit the cooling needs in a residential building. The passive cooling strategies that gains control over heat dissipation is considered as suitable for consistent climatic areas whereas in modern houses, the changing temperature is a major issue being faced by the occupants (Chua et al. 2013). The poor design of buildings often causes the heat to be trapped that increases indoor temperature. The roof area and surrounding walls of a building is considered as the most critical part due to the fact that these are exposed to heat being caused by high solar radiation. The determination of proper design strategies will help to effectively reduce the consumption of energy in a building as well as provide comfort to the occupants (Vakiloroaya et al. 2014). This particular study has been undertaken to determine the effective design strategies for air conditioning in a residential build ing so that the comfort requirement of occupants are fulfilled with respect to the changing climate. Motivation for research The developing countries majorly that are located in tropical regions have dry climate and there is existence of special problems due to extreme heat retention by the buildings if ventilation is not adequate for cooling at night. A major portion of the buildings being designed in such climatic regions are not suitable for occupants as those are poorly designed and no design strategy is adapted for the climate (Alibabaei et al. 2017). The residential buildings are often designed without considering the parameters that are responsible to ensure thermal comfort along with efficient use of energy. Hence, the dependence on artificial lighting and ventilation is prevalent in almost every residential building. However, power disruption on a frequent basis and load shedding during the summer or hot days makes the life of occupants much troublesome. The circumstance turns out to be more terrible during the hot summer days in between the period of mid-March and early May as there is gradual in crease in the surrounding temperature (Yang, Yan and Lam 2014). Amid this period, the demand in the use of electricity goes up to its most elevated amount due to hot weather and in addition the demand increases to supplement the cooling requirements in the residential buildings. The buildings that does not have dynamic strategies to meet the cooling requirements during the rising demand of energy will incur poor indoor atmosphere. This often leads to exhaustion along with issues related to health and safety (Taleb 2014). This study will deal with describing the approach for passive air conditioning design strategies suitable in residential buildings. The poor design of buildings often causes the heat to be trapped that increases indoor temperature. The roof area and surrounding walls of a building is considered as the most critical part due to the fact that these are exposed to heat being caused by high solar radiation. The determination of proper design strategies will help to effectively reduce the consumption of energy in a building as well as provide comfort to the occupants. There are two fundamental techniques for cooling of residential buildings in a tropical atmosphere and they are oppositely inverse in nature. It is imperative to comprehend the core philosophy of both the strategies to confirm that could be appropriately adjusted for residential buildings (Shirazi et al. 2016). Commonly, a plan that is genuinely dedicated to one technique or the other, cannot generally be effectively changed over into the other. The principal procedure is passive cooling. Out of the two methodologies, this is the one that can be considered naturally dependable and having a place with economical plan. Homes with passive cooling uses extensive open areas for allowing cross-breezes through the spaces very easily and utilize openings in high regions to enable warmed air to rise and escape (Kim et al. 2016). The objective of passive cooling is to utilize normal conduct of air to upgrade ventilation and diminish inside temperatures in fabricated spaces. The second techniqu e is mechanical cooling. Mechanical cooling utilizes equipment to accomplish cooling of interior spaces. Clearly, mechanical cooling can help to achieve thermal comfort by substantially higher decrease in temperatures that is not possible by means of passive cooling (Yoon, Bladick and Novoselac 2014). Despite the fact that there is energy being spent, though passive cooling utilizes no energy, this does not imply that mechanical cooling is not economics dependable. Hence, this research is based on determining the suitable air conditioning design strategy for residential buildings. Research questions The aim of this research is to study the air conditioning design strategy for a residential building. It is one of the most critical criteria or issue being faced by the occupants of building situated in a rigorous changing climatic zone. Some of the research questions that are prepared to conduct this study in details are provided as below. Objectives of the research The implementation of proper design strategy for air conditioning in residential building is an essential element to fulfill the cooling requirement of the occupants. The buildings situated in continuously changing climate needs proper design strategy for installation of air conditioning. The objectives that have been prepared for conducting this particular research are presented as below: To determine the capabilities of existing HVAC system or other cooling system for matching the cooling requirement of occupants of a residential building. To identify whether the adapted strategy is suitable for the residential building in terms of energy consumption. To evaluate the benefits of determining suitable air conditioning strategy for residential buildings.
