nzeb design - principles for eco-homes• orientation for maximum solar gains, active + passive
• positioning to minimize energy losses by natural wind + sun shelter (topography and vegetation)• compact shape to minimize surface area + save materials to conserve energy• insulation for external surface to minimize energy losses• thermal mass to store energy gains from heating systems + passive solar• thermal zoning to use secondary rooms as a heat-buffer• building materials should be low impact (i.e. local and minimal embedded energy), non-toxic, recycleable (in a sensible manner), durable • fenestration to suit the solar orientation• owner involved in design and creation for self-empowerment and connection to their home environment• reduction of footprint to a bearable minimum - requires intelligent design and enhances the fun - get rid of the superfluous, develop the essentials to their optimum
