nZEB design: challenging between energy and economic targets
نویسندگان
چکیده
Currently nZEB design represents a negotiation between energy targets and economic concerns. Whereby, it is indispensable that, staring from very preliminary phase of the project, a synergy between the building and system designers, the energy consultant and the economic valuer is set up. Cost-optimal methodology together with statistical analyses developed with Minitab software was applied to analyze a new high performing single-family house, in Northern Italy, in order to define how energy and economic aspects could influence the preliminary design phase of the project. © 2015 The Authors.

Fulfillment of net-zero energy building (NZEB) with four metrics in a single family house with different heating alternatives
This study aims to investigate the fulfillment of four Net Zero Energy Building (NZEB) balances, NZEB-PE, NZEB-site, NZEB-emission and NZEB-cost, considering the four metrics of primary energy (PE), site energy, CO2-eqemissions and energy cost, respectively, using weighting factors based on Finnish and international reference data. The study analyzes five conventional energy systems and seven b...
متن کاملAdvanced Strategies for Net-Zero Energy Building: Focused on the Early Phase and Usage Phase of a Building’s Life Cycle
To cope with ‘Post-2020’, each country set its national greenhouse gas (GHG) emissions reduction target (e.g., South Korea: 37%) below its business-as-usual level by 2030. Toward this end, it is necessary to implement the net-zero energy building (nZEB) in the building sector, which accounts for more than 25% of the national GHG emissions and has a great potential to reduce GHG emissions. In th...

This study was born in the context of new challenges imposed by the recast of the EU Energy Performance of Buildings Directive. The aim of this work is to develop strategies to identify and investigate the relationship between decisional variables within a nZEB design concept, providing a useful method to deal with a huge number of simulations corresponding to a large number of building configu...
متن کاملA Governance Perspective on Net Zero Energy Building Niche Development in India: The Case of New Delhi
The net zero-energy building (NZEB) concept has recently gained prominence worldwide. Large scale adoption and implementation of NZEBs would potentially contribute greatly to greening of the building sector. However, it is still at a nascent stage of niche formation. This paper aims to assess the governance context for adoption and uptake of NZEBs through niche formation in India by addressing ...
