Detailed explanation-1: -Nearly zero-emission building (NZEB) means a building that has a very high energy performance, while the nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby.

Detailed explanation-2: -A zero net energy building (ZNEB) is one that is optimally efficient, and over the course of a year, generates energy onsite, using clean renewable resources, in a quantity equal to or greater than the total amount of energy consumed onsite.

Detailed explanation-3: -Zero energy building generates its energy resources without relying on energy grid supply. The net-zero design principle provides the ease to the building users even in the extreme conditions, the more extreme exposure to the elements the higher energy requires for the comfort [15].

Detailed explanation-4: -1. The Unisphere, Maryland, U.S.A. Spread across an area of 135, 000 square feet, The Unisphere stands in the middle of the city in downtown silver spring as a sterling example of technologies embodied, making it a fully sustainable, net-zero energy construction.

Detailed explanation-5: -A net zero carbon building is “highly energy efficient and powered from on-site and/or off-site renewable energy sources, with any remaining carbon balance offset.”
