set a research goal of making commercial zero-energy buildings (ZEBs) marketable by 2025. 1 In concept, a ZEB has greatly reduced energy loads such that renewable energy can supply the remaining energy needs. This immediately begs some questions: " This is a far stretch from our current energy-efficient buildings—is it even possible? " " Are there examples out there that are even close? " To address these questions, the National Renewable Energy Laboratory (NREL) conducted an assessment of the…

Zero-Energy Buildings-A Review

A zero-energy building (ZEB), which is an autonomous building energy option, is defined as a building that produces as much energy as it uses from renewable energy sources at the site. Zero-energy


A ‘ZERO ENERGY BUILDING (ZEB) is a building with annual net energy consumption nearly equal to zero. With recent advances in building technology ZEB has gained a worldwide attention and it is

Towards net zero energy office buildings in Spain: a review of 12 case studies.

The paper presents a comparative analysis of twelve existing office buildings located in Spain which have been conceived as zero-emissions or low-energy buildings. A synthetic analysis has been

Transitioning to a 100% renewable energy system in Denmark by 2050: assessing the impact from expanding the building stock at the same time

Residential and service (office) buildings consume a large proportion of primary energy in Europe in the form of electricity and all other energy carriers. In response to this, the concept of near

Investigations of a Cost-Optimal Zero Energy Balance: A study case of a multifamily Net ZEB in Denmark

The Net Zero Energy Building (Net ZEB) concept is worldwide recognised as a promising solution for decreasing buildings' energy use. Nevertheless, a consistent definition of the Net ZEB concept is

Strategic Decision Making For Zero Energy Buildings in Hot Climates

The Net Zero Energy Buildings (NZEBs) objective has raised the bar for sustainable development among architects and developers in hot climates. The objective of this paper is to investigate the

A methodology towards achieving Net zero energy performance for high-rise residential buildings in Australia

Achieving Net zero energy (NZE) standards for high-rise residential buildings is a significant challenge. One of the challenges is the absence of detailed design guidelines for selecting systems,



Zero Energy Buildings: A Critical Look at the Definition; Preprint

A net zero-energy building (ZEB) is a residential or commercial building with greatly reduced energy needs through efficiency gains such that the balance of energy needs can be supplied with

Assessment of the Technical Potential for Achieving Zero- Energy Commercial Buildings

The U.S. Department of Energy's Building Technologies Program has adopted the goal of making zero-energy commercial buildings (ZEBs) marketable by 2025. The National Renewable Energy Laboratory

Lessons Learned from Case Studies of Six High-Performance Buildings

Commercial buildings have a significant impact on energy use and the environment. They account for approximately 18% (17.9 quads) of the total primary energy consumption in the United States (DOE

Improving Sustainability of Buildings Through a Performance-Based Design Approach

The design of most buildings is typically driven by budget, time, safety, and energy codes, producing buildings that just meet these minimum criteria. To achieve better or even exceptional energy
