Sustainability in Construction and the Integration of Building Essay
Sustainability in Construction and the Integration of Building Services - Essay Example It is in this context, two documents were determined to provide solutions to the built environment designs. The solutions proposed were different from one another because the first one was a proactive solution and the second one was a reactive solution to climate change. The CIBSE Briefing 8 (2003) was focused on providing new buildings and refurbishments design and operation solutions. The purpose of this proactive solution was to minimise or reduce the use of energy, which was identified as the major source of carbon emission that causes climate change. Meanwhile, the CIBSE Briefing 10 (2004) provided solution that focused on the reduction on the impact of climate change on the built environment. It is considered as a reactive solution because the design responded to the effects of climate trend to the built environment particularly to the thermal comfort. On the other hand, the former briefing was considered as proactive solution because it tried to prevent the causation of climat e change before it emerges. Further, both the information on the briefings was considered useful. However, the application of the building designs could be practicable to new buildings and refurbishments. It could also be used for existing buildings at the expense that it would need massive renovation. Likewise, the built environment design strategies that will be presented in the discussion could be considered in designing a social housing development in an inner city because they ensure economic and environment sustainability. Discussion Designing buildings to address the cause of climate change In the first document, the high consumption of electricity was the key issue. Therefore, it provided several recommendations which will serve as guidelines for the engineers and building designers in designing new built environmnet. The purpose was to provide the required internal environment and services with minimum energy use in a cost effective and environmentally sensitive manner (CIB SE, 2003, 1). The recommendations have included the following: energy- efficiency should be integrated in the clientââ¬â¢s brief with all the necessary details support such as energy consumption targets, power density, and energy-efficient equipments to be installed, i.e. CHP or variable speed drives. The energy-efficient plan document should be compared to the standards set by the regulation policies. At the same time to be constantly reviewed while the design is in its installation process. The briefing also recommended that in designing building, design team should be considered and appointed before the building started in order to ensure good interaction between the disciplines. Project targets and life cycle costing should be utilized to promote teamwork. Third recommendation, design built form and services carefully in order to keep energy demand to a minimum. Further, using renewable energy sources, ambient energy and passive solution was also suggested in order to achieve this objective. Fourth, the use of ventilation hierarchy (see diagram below) as a guide was also recommended in order to minimize uncontrolled air infiltration. If possible find economical and environment friendly way to generate ventilation. Avoid the use of air conditioning since it could consume up to 50% of energy.
