Good design
Good design is to control over how an object is shaped, and its intended purpose. It involves not only what colour a house should be, but start out with question of function, before addressing issue such as material use, land use and planning.
Good design means: not designing buildings which rely heavily on technologies as air conditioning to keep them comfortable or liveable, because doing so will lead only to a building using more energy and may even make the building unhealthy to work or live in;
Windows should face the direction that can allow them to make the most of solar gain like natural heat and light; it also means not to create more parkings, roads or out of town development to solve traffic problems, because doing so is likely to increase traffic growth; increasing durability of a building so that environment costs are spread over a longer useful life;
Increasing the technical efficiency of resource conversion, for example through greater energy effiency or recovery of waste heat;
Including use of as many eco-friendly matarials as it possibl;
Protecting occupant health and improving employee productivity.
To make the best design Design Quality Indicator (DQI) can be used. It is an assessment tool to evaluate the design quality of buildings.
Specification:
In environmental building design, many of the changes needed are of a technical nature and may involve no more than making different choices over issues such as materials specification. Through simple choices made in design construction, we can do much to reduce building construction impact on the environment. Large volumes of potentially reusable components are landfilled and lost to the system only to be replaced with similar components.
E.g.:
Columns, Mantles, Lumber, Moulding, Insulation, Steel beams & studs, Siding, Wainscoting, Brick, Electrical equipment, Plumbing fittings, Light fixtures, Interior doors, Faucets, toilets, windows, bathtubs and many other.
