“…Yohanis and Norton calculated the life-cycle energy (operational and embodied) of a UK generic single-storey office building, using Early Design Model EDM [68], which is an integrated simplified energy model based on a proven well-established algorithm, and studied the energy effects on the capital costs. They found that, there is a critical ratio of glazing which affects the balance between embodied and operational energy: embodied energy is higher below about 55%, but operational energy is higher above 55% glazing.…”

Life-Cycle Assessment (LCA) is one of various management tools for evaluating environmental concerns. This paper reviews LCA from a buildings perspective. It highlights the need for its use within the building sector, and the importance of LCA as a decision making support tool. It discusses LCA methodologies and applications within the building sector, reviewing some of the life-cycle studies applied to buildings or building materials and component combinations within the last fifteen years in Europe and the United States. It highlights the problems of a lack of an internationally comparable and agreed data inventory and assessment methodology which hinder the application of LCA within the building industry. It identifies key areas for future research as (i) the whole process of construction, (ii) the relative weighting of different environmental impacts and (iii) applications in developing countries

“…EDM (Fig. 1) is an integrated and simplified energy model based on proven well-established algorithms and, being spreadsheet-based, is simple and flexible [36]. Included in the EDM are a generalized correlation for solar energy utilization [37] and a facility for preliminary cost evaluation [38].…”

“…It is assumed that the temperature in a room remains constant for the duration of the simulation. For a particular building description data set, good agreement has been obtained [36] between the annual heating energy predictions of EDM and that of SERI-RES; the latter is a detailed hour-by-hour simulation model [39,40]. During the heating season, the differences in prediction of heating energy varies from þ2.86 to 26.48 per cent with EDM over-estimating [36].…”

“…It predicts the potential Fig. 1 Simplified chart of the EDM [36] performance of the building, assuming that systems and occupants function optimally and rationally, respectively. It then follows that its energy predictions are not always likely to be similar to monitored data.…”

“…Their design and construction has both direct and indirect impacts on life-cycle energy use. A representation of cost, operational, and EE of design options can be undertaken using the early design model (EDM) [36]. Simplified models render it practicable to quantify the total amount of energy consumption over the life cycle of a building.…”

Elevated operating temperatures reduce the solar to electrical conversion efficiency of building integrated photovoltaic devices (BIPV). Phase change materials (PCM) can be used to passively limit this temperature rise although their effectiveness is limited by their low thermal conductivities and by crystallization segregation during solidification. This paper presents an experimental evaluation of the effects of convection and crystalline segregation in a PCM as a function of efficiency of heat transfer within the finned PV/PCM system. The thermal performances of bulk PCM with crystallization segregation for different internal fin arrangements are presented. It is noted that the addition of internal fins improves the temperature control of the PV in a PV/PCM system.
