“…According to Knowles, et al [16,17] the longer axis of the building should laid along east-west direction for minimum solar heat gain by the building envelope [18,19,20] Proper orientation of buildings to reduce the impact of unfavorable weather conditions like solar radiation, driving rain and thunderstorm. In the house, the rooms should be located in such a way that the ones frequently used should be elongated along the east-west dimensions to mitigate heat gain in summer and also making efficient use of sun.…”

As the price of energy goes up, more and more concern has been focused on the sustainable development of residential houses. One of the best solutions would be construction of low energy consuming "passive" houses. A study of residential buildings in The Gambia shows that most occupants of the buildings have persistent and growing problems with the indoor environment. Most buildings are characterized by poor design in relation to the climate, which requires a great deal of energy for cooling during extreme climate. Other problems are poor natural ventilation, inadequate surface volume ratio and poor building orientation. The main question analyzed was whether comfort is achievable solely by the use of passive design strategies, or if energy consuming mechanical systems are required. However, there is no official residential passive housing standard at the present time in The Gambia. This paper focus on the experimental and numerical investigations to determine how the building construction mass, the climatic parameters and the management of air changes rates behave on the effectiveness of natural ventilation and on indoor comfort conditions. Using portable thermometers monitoring instruments data were acquired during a period of a hottest summer phase, in parallel with occupancy survey. Passive cooling techniques can reduce the peak cooling load in buildings, thus reducing the size of the air conditioning equipment and the period for which it is generally required. This paper reviews and critically analyzes various passive cooling techniques and their role in providing thermal comfort and its significance in energy conservation.

“…In NC, the passive cooling design strategies employed should be backed up with an auxiliary mechanical airconditioning system. However, it is possible to achieve thermal comfort for times when relative humidity is between 40 and 60% by an appropriate physical design with air movement effect [31]. An SEV system, integrated into the multi-purpose chimney as shown in Figure 2(b) can be constructed to take out the warm air from the living room, replaced by cooler air admitted through north-facing openings of the building perimeter.…”

SUMMARY In many countries, although solar energy is plentiful, due to technical and economic issues, micro‐scale solar energy technologies have not properly found their places in the market. The present work demonstrates the convenience of employing economic feasibility assessments together with engineering analyses before applying solar strategies during the design stages, in order to convince house owners that these solar technologies can be economically viable. In a case study, this approach is tested for a real house project developed in North Cyprus (NC) in which solar energy applications for electricity generation, hot water preparation, space heating and passive cooling are investigated. It is reported that grid‐connected photovoltaic (PV) systems would be economically feasible with savings‐to‐investment ratio (SIR) values of 2.9 to 3.4. A thermal performance analysis is carried out for a thermal storage wall (TSW) together with a direct solar gain (DSG) window in the living room. It is discovered that the temperature range of the living room was within 18–22 °C throughout the majority of winter days. This application is also proved to be economically feasible with an SIR of 1.3, compared to installing an 18,000 Btu/h heat pump. It is determined that both locally produced solar water heaters and imported solar water heaters (ISWHs) are economically viable compared to using a 3‐kW storage‐type electric water heater. Their SIR values are estimated to be 7.5 and 3.7, respectively. A solar‐assisted stack‐effect ventilation (SEV) system is verified to have techno‐economic feasibility and is also useful in concealing the unattractive cold and hot water storage tanks on the roof. The prospective house owner decides to invest 3840 EUR in installing a grid‐connected PV system of 1 kWp, an ISWH, a DSG window, building a TSW for space heating and a SEV system with an overall SIR value of 3.2. This procedure can be developed into a government policy where all these assessments are made mandatory to increase the awareness of the home builders before they make their decisions about the final designs of their houses. The present work demonstrates the convenience of employing economic feasibility assessments together with engineering analyses before applying solar strategies during the design stages, in order to convince house owners that these solar technologies can be economically viable. In a case study, this approach is tested for a real house project developed in NC in which solar energy applications for electricity generation, hot water preparation, space heating and passive cooling are investigated.
