- Description: M.Phil. , The building/construction industry is undeniably one of the largest; it however is also one of the most inefficient. These inefficiencies span design, construction and the operational phases. The depletion of natural resources and the need for sustainability has however created an urgent need for Architecture, Engineering and Construction (AEC) consultants to address these issues and develop life-cycle integration systems capable of eliminating or substantially reducing waste and efficiently managing the complex process of building design, construction and building operations management. Such systems may be based on advanced production techniques developed in the aerospace industries for the US military and subsequently adapted for use in the industrial manufacturing industry. This dissertation will attempt to explore the following: 1. Identification of current trends in the AEC industry including global warming and sustainable development, to determine the impact on the Building Industry. 2. The relevance of life-cycle engineering and Lean Production philosophy for the AEC industry. Of particular interest is how System life-cycle engineering will benefit the trend towards 'green' environmentally sustainable buildings. 3. Analysis of the AEC Design/Construction/Operation process (Project life-cycle), with the intention of identifying major weaknesses and strengths. 4. Information systems (current and future) and how these are driving change in the industry. Information systems as a backbone for the implementation of a proposed systems framework. The possible implications of life-cycle systems implementation for the architectural profession and other AEC professions will result in new proposed structures, obstacles and opportunities.

- Description: This paper reviews designs of the built environment from a sustainability perspective, emphasizing their importance in achieving ecological and sustainable economic objectives. The built environment has traditionally resulted in loss of biodiversity, extinction of some species, climate change, excessive water use, land degradation, space depletion, waste accumulation, energy consumption and environmental pollution. Materials used like plastics, metals, bricks, concrete, cement, natural aggregates, glass and plaster have wreaked havoc on the earth´s resources, since they have high levels of embodied energy hence not sustainable. Additional resources are consumed during use and disposal phases. Proposed designs for sustainability solutions include: ecological sanitation and eco-efficiency systems that ensure social, economic, environmental and technical sustainability. Renewable materials and energy systems, passive cooling and heating systems and material and energy reduction, reuse and recycling can improve the sector. These ideas are intended to inform the field of ecological design of the built environment.
