Environmental Assessment Methods

What makes a building efficient?

The need for more sustainable housing arose around the 1970's when people realised the way in which we are consuming fossil fuels is unsustainable and we need to find another way of building good quality housing for the rapidly growing population; and at the same time finding sustainable methods of doing so. The most energy efficient home produces more energy than it consumes over its lifetime. 
Case studies below show the use of environmental studies in act.

Afterlife Of A Building

At the end of a project an audit should be carried out; an EIA (Environmental Impact Assessment) audit evaluates the performance of an EIA by comparing the actual impacts to those that were predicted. The main objective of an audit is to improve future environmental assessments.

How To Make Your Home Energy Efficient:

  1. Energy saving lightbulbs last 8x longer
  2. Installing the recommended 270mm of loft insulation can save £110 a year. If your house was built after 1920 a third of heat is lost through walls
  3. Soft furnishings (pillows and rugs etc.) help to retain heat.
  4. Double glazing can cut heat loss by 50%
  5. Save water - approximately 40% of water in homes is wasted. Low flow toilets help to save water and recycling rainwater.
  6. Trap the sun- solar panels heat up water or photovoltaic (PV) panels convert sun directly into electricity.
