A net-zero house is a structure that consumes only the energy it produces. Reports suggest that the net-zero energy building movement has hit critical mass after being considered a fringe goal for a long time. Net-zero housing has earned its place in the mainstream, and is a combination of many of the topics discussed in the list. For now, Research and Market’s report suggest that the market is registering growth due to the increasing number of initiatives regarding energy efficiency by the government and rising need for net-zero energy buildings to reduce GHG emissions.
Space Efficiency
Kaka says that efficient use of space produces considerable environmental and economic benefits. Some of the ways the construction sector can achieve space efficiency are: maximising the use of daylight in the interiors, incorporating requirements for space efficiency into project briefs and design, systematically collecting and updating space and cost information as well as setting targets that are monitored, incorporating space efficiency concepts into the estate strategy and minimising surface area by excluding conservatories, extensions, and porches in the design. Space efficiency can ensure that the size of the structure stays small, reduces the need for construction materials and allows a greater number of people to live in the same space together harmoniously, all factors aiding construction in the urban environment to be more sustainable.
