HVAC&R systems are the most energy consuming building services, representing approximately half of the final energy use in the building sector. Despite their significant energy use, there is a lack of a consistent and homogeneous framework to efficiently guide research, mainly due to the complexity and variety of HVAC&R systems, but also to insufficient rigor in their energy analysis. Quantifying the energy consumption characteristics of HVAC&R system is complicated, because the energy savings provided by this system depend on various factors. This research evaluates energy consumption characteristics of HVAC&R systems, with the aim of establishing a common idea for the analysis of building energy efficiency. The objective of this study is to develop an energy evaluation methodology and a simple simulation program that may be used by engineers and designers to assess the effectiveness and economic benefits of HVAC&R systems. Our approach deals with the concept of HVAC&R system energy use aggregation levels that are composed of subsystems. To carry out a techno-economical estimation of HVAC&R systems considering different types of subsystems, the matrix combination analyzed, and a total of 960 HVAC&R systems can be implemented for a large-scale office building. The methodology of energy analysis that was carried out in this study highlights how to plan and design toward utilizing the most effective HVAC&R systems.

This technical report gives a review of 30 fully documented net ZEBs case studies that have been
identified by the Sub Task C participants. It reports a compilation of all technical and non-technical
information of the 30 case studies that formed the foundation on which the analysis of Volume 3 of the
Source Book was based.

Towards Net-­-Zero Energy Solar Buildings
February 2014 - PDF 0.18MB
Energy use in buildings worldwide accounts for over 40% of primary energy use and 24% of greenhouse gas emissions. Several International Energy Agency (IEA) countries have adopted a vision of so-called ‘net zero energy buildings’ as a longterm goal of their energy policies. However, what is missing is a clear definition and international agreement on the measures of building performance that could inform 'zero energy’ building policies, programs and industry adoption around the world.

Evaluation Tool for Net Zero Energy Buildings: Application on Office Buildings

Within the research project “IEA SHC Task 40 – ECBCS Annex 52: Towards Net Zero Energy Solar Buildings” an excel-based tool was developed to assess balance, operating costs and load match index for predefined selected Net ZEB definitions [1]. The tool can be of assistance for different stakeholders, including building designers (evaluation of building design solutions with respect to different Net ZEB definitions), energy managers (assess the balance in monitored buildings) and policy makers (assist in the upcoming implementation process of Net ZEBs within the national normative framework).

Net Zero Energy Building
Living and Working with an Equalised Energy Balance

Publisher: Detail.de
Strategies and experiences from the perspective of planners and users: Net zero energy buildings, equilibrium buildings or carbon neutral cities – depending on location and the reasons for making the calculation, the numbers are run differently. The variety of terms in use indicates that a scientific method is still lacking – which is a problem not just in regard to international ommunication, but also with respect to planning processes as a response to energy challenges. The clarification and meaning of the most important terms in use is extremely important for their implementation.

The objectives of the project ‘Towards Net Zero Energy Solar Buildings’ are to study current net zero, near net zero and very low energy buildings and to develop a common understanding of a harmonised international definitions framework, tools, innovative solutions and industry guidelines. To achieve these objectives the project will document and propose demonstrations of practical net zero energy buildings (NZEBs) with convincing architectural quality.

Energy use in buildings worldwide accounts for over 40% of primary energy use and 24% of greenhouse gas emissions1. Energy use and emissions include both direct, on-site use of fossil fuels as well as indirect use from electricity2, district heating/cooling systems and embodied energy in construction materials.
