“…To overcome this issue, the authors investigated cooling load demands for inclined walls with 50% façade areas on the south side of buildings in Ebbw Vale and London (both in the UK) and compared it to a simple cube shape building having the same façade area. The simulation indicated that the wall inclination has a noticeable impact on summer cooling up to an inclination angle of 115 • from the horizontal [25].…”

This paper investigates various building material effects on the cooling load requirements of a typical two-floor house located in the Midwest region in the USA. A survey was done for various building materials along with their prices in the US market. Various building walls, lighting, window glazing, and insulations were used for simulation as single and combined cases. The return on investment from savings in the electrical load consumption against the materials cost was investigated. It was found that the best single case savings and investments were for cases when lights were changed from incandescent lighting with 20 W/m2 to fluorescent bulbs, or when using double skinned walls with 5 cm rock wool or expanded polystyrene insulation. Combined cases, combining more than one single change, offered more reductions in cooling loads but were associated with higher initial costs and, thus, longer returns on investment. The best case recommendation was for buildings with a 20 cm hollow concrete block (HCB) when combined with fluorescent lights and double pane heat-absorbing glazing for windows. Although these recommendations were for a typical house in the Midwest region of the United States, a similar analysis could be adopted by designers and building owners to optimize the energy consumption in their buildings. The final design decision should be based on an optimum correlation of the air-conditioning units’ size and cost, running and maintenance costs, the return on the investment duration, and the available usage area in the building.

“…The buildings' envelope geometry and its effects on cooling and heating demands were investigated by Lavafpour & Sharples [25]. It has been argued that super-insulated homes are vulnerable to excessive heating in summer especially in cities where heat islands are more present.…”

“…Since a façade functions as the interface for obtaining natural light and solar energy in a building as well as for the outward appearance [Hausladen et al, 2008], research on façade design involves a wide range of issues, such as aesthetics, user preference, human behavior, lighting, indoor thermal comfort, natural ventilation and energy consumption [Cheung and Chung, 2008;Alkhresheh, 2012;Hochberg et al, 2010;Gagne and Andersen, 2012;Smith and Levermore, 2008;Lavafpour and Sharples, 2014;You et al, 2013]. In the past decade, as natural lighting has been shown to be environmentally benign and psychologically satisfying for living and working [Leslie, 2003;Du and Sharples, 2011], an enormous amount of research has been conducted on how windows influence overall interior daylighting [Bougdah and Sharples, 2009;Lartigue et al, 2013;Baker and Steemers, 2002].…”

Overcrowding in the perimeter zone is an inevitable issue in residential rooms with limited space. Obstructions, such as furniture and household items, may block the existing windows, and therefore affect interior daylight conditions. A façade design approach is needed that simultaneously takes into account daylighting and the volume of usable space for obstructions in the perimeter zone of such rooms. This study simulates daylight distributions in a typical small residential room with obstructions in front of windows. The simulation consists of two parts. First, the effects on horizontal illuminances caused by different positions and shapes of obstructions are examined under an overcast sky. Second, the maximum usable space volumes for obstructions of 51 optimized façade configurations are calculated in terms of four window-to-wall ratios (W W Rs). The results of this study show that optimizing the forms of facade design can increase the usable interior space volume and meet the daylighting requirements of Chinese standards for small residential rooms. Additionally, by using the optimized façade forms, a façade with a W W R value of 50% provides the maximum usable space for obstructions. Based on the above results, this paper presents two matrices that can help architects in selecting the appropriate fenestration methods and confirming the size of usable space and allocation for residents.
