A development of environmental conscious design of prison buildings

Environmental conscious design refers to variety of approaches in architecture design that covers technical, behavioural, and functional aspects (Goulding et al, 1992). These approaches usually include contradictory measures with social indicators (Sykes, 1995; Norton, 1999). The contradiction is magnified in incarceration architecture, which is very specific type of buildings (McConville, 2000). Prison buildings represent the split between the society requirements and the needs for the users, in this case the prisoners, to have comfortable environment. Energy as an ultimate natural resource reflects both the cost to the society, in terms of cooling/ heating load and the need for comfort and rehabilitation of prisoners (Al-Hosany and Elkadi, 2000). Different energy codes tend to control the thermal behaviour of buildings in certain environment in order to maximise their energy efficiency (e.g. CIBSE, 1999). In prison buildings, some of the main variables of such code are not relevant. While energy codes, for example, regulate the use of glass in buildings by either minimise the openings size (prescriptive criteria) or by determine an overall limit of heat transfer (performance criteria), the objective in prison buildings is to minimise glass areas for security purposes. This leads in turn to reduction in visual and comfort levels in prison cells. The aim of this paper is to address the balance between the society requirements of reducing energy consumption in prison buildings and the need for humane and comfortable environment for prisoners in order to maintain sustainability. The paper investigates the possible role of façade technologies to bridge the gap between requirements of both society and prisoners.<br /><br />
