Scope:

This participatory workshop explores the potential for informative and practical guidelines for the operation of buildings and input for the building regulations. The aim is to discuss what information and data are needed, how it should be provided, and how it might be applied with regard to the updating of a number of standards in this area. Data from operational performance of HVAC systems and components (results from the project iSERVcmb) need to provide information about what can be achieved in the building´s operation. In the workshop the focus will be on operational data from HVAC systems/components, what can be found from the data at the operational level versus legislative needs, and what opportunities exist to improve the operational performance of HVAC equipment.

Short description:

A European Survey on healthy homes, carried out with 14.000 respondents in 14 countries, shows that comfort, health and energy savings is the main driver for renovation of the building stock. The characteristics for the healthy home is good sleeping conditions,  comfortable indoor temperature, access to fresh air, good daylight conditions and appropriate humidity levels. Those topics are a part of the evaluation of buildings based on the Active House vision and has been a part of the modernization of the social housing renovation concept RenovActiv, which is the first affordable and easy to reproduce climate renovation in Brussels. The 80 m² dilapidated semidetached house built in the 1920s has been moidernized with focus on comfort, health and good indoor climate conditions.

Speakers:

Armin Knotzer, AEE Intec: RENEW school and Austrian deeply renovated schools

Jørgen Rose, Danish Building Research Institute: Examples of deep-renovation in school buildings

Pawel Wargocki, DTU Byg: Do new and renovated European schools and kindergartens secure high indoor environmental quality?

Christian Anker Hviid, DTU Byg: Robust façade designs

Scope:

Schools desperately need upgrading to improve the indoor climate to the benefit of all pupils, and to save energy in the context of the European nZEB goals. Several efforts and projects like IEA-Annex 61, Renew School, SchoolVentCool, School-of-the-Future have shown that it can be done and documented the benefits.

Pre-fabricated timber elements are widely used for new schools and day-care centers but lacks momentum when it comes to renovation of schools. Despite the obvious advantages: renovation during the summer holidays, better quality control and no relocation of pupils.

This workshop seeks to disseminate knowledge about deep renovation and pre-fabrication methods, to discuss and disclose the barriers, and to motivate massive-scale pre-fabricated façade renovations in Denmark and in Europe.

Scope:

Maintaining the correct temperature difference in a HVAC system is of great importance. A too low temperature difference leads to increased water flow and hence an increased risk of noise. All though noise is a serious problem in eg. apartment buildings, the biggest disadvantage is undoubtedly the increased flow and the derived consequences, which are numerous. Eg. condensing boilers may not be able to operate in condensing mode, and increased pipe pressure losses leads to increased pumping cost. If the system is directly connected to a District Energy system, also this network is affected. Besides this, it is often a struggle to control the temperature difference in eg. one-pipe HVAC systems. Not only HVAC systems may be operated inefficiently. Large DHW circulation systems are by tradition fitted with constant speed pumps that are running at maximum speed 24/7. This will lead to overflow, increased heat losses and pump power overspending. Latest HVAC pump generations are much more than pumps. They offer innovative control modes that will reduce the consequences of the challenges described above. Control modes such as constant differential and constant temperature mode are designed to increase system controllability and efficiency.

Presenters:

• Frank Hovorka, UNEP Financial Initiative, Sustainable Building Alliance
• Ian Knight, Welsh School of Architecture, Cardiff University
• Thomas Toftgaard Jarløv, Copenhagen Airports
• Ole Teisen, Sweco Danmark A/S

Scope:

Today there is demand for Building Commissioning in almost all building projects. Many building owners have realized that the technical complexity of buildings has increased and it is necessary to manage the quality of any building work to fulfill the requirements of the owner. However, the requests for commissioning services often lack basic knowledge of how to set up the commissioning organization, the leadership, the scope, the activities in the pre-design, design, construction and operations phases, and the money needed for the investment in this quality management process. Main objectives:

• Provide insights into how Building Commissioning is performed, how it interacts with sustainability measures and how it influences the value of buildings.
• Map market demand for tools, guidance, certifications, investigations and documentations in the future work with Building Commissioning
• Map knowledge gaps to give input to the REHVA Commissioning Task Force elaborating a REHVA Building Commissioning Guidebook focusing on the commissioning of retrofits.

• Michele Liziero -  EnergyTeam SPA, Italy       
• Jan Mehnert - synavision GmbH, Germany
• Niels Delaere - Factor4, Belgium 

Scope:

The tremendous advances in technology and the integral approach to building concepts enable us to design, build and operate highly energy efficient buildings - principally. Unfortunately, complexity of hydraulics and automation has also increased. As a result, we face a new risk with high intensity: tackling the lack of quality in building performance will be the decisive challenge for buildings.

QUANTUM, a research project within Europe’s Horizon 2020 framework, develops and demonstrates pragmatic services and appropriate tools supporting quality management for building performance in the design, construction, commissioning and operation phase as a means to close the gap between predicted and actual energy performance in European buildings.

The workshop will discuss current risks for building performance and present a specific quality management approach as a promising answer. Three innovative tools will be demonstrated to show how we can effectively introduce quality management in building projects to improve building performance.

Short description:

The social and environmental urgency of large-scale integrated retrofitting of the European building stock is widely acknowledged. However, the building sector has not been able yet to devise a structural, large-scale retrofitting process and systematic approach. There is an urgent need for cost-effective solutions to accelerate deep renovation of buildings. Important is to promote deep renovation is to use the right balance between the energy conservation and efficiency measures for one side and the measures and technologies that promote the use of renewable energy on the other. As well as the optimization of material use versus energy reduction.

New opportunities like the application of prefabricated modules for building renovation could be one of the solutions for this. A combination of product innovation, fully automated production processes and new market models have the potential to reduce costs, reduce the renovation time and disturbance for occupants and, at the same time, enhance quality and performances, both in terms of energy efficiency as indoor climate.

In this workshop the latest finding a from key projects on cost-effective deep renovation will be presented as an introduction to further discussions. Projects addressed will be:

• H2020 MORE-CONNECT: Development and advanced prefabrication of innovative, multifunctional building envelope elements for Modular Retrofitting and smart Connections
• H2020 EE REFURB: Regional process innovations for Building renovation packages opening markets to zero energy renovations
• IEA EBC Annex 56: Cost Effective Energy and Carbon Emissions Optimization in Building Renovation

Organiser: IEA DHC Annex TS1: "Low Temperature District Heating for Future Energy Systems"

www.iea-dhc.org  

Short description:

Low temperature district heating offers a fairly easy and cost effective way to realize a fossil free heating system compared to solutions based on renewable energy production on each building. The utilization of low network temperatures is an economically competitive approach to the heating energy supply of communities because of the easy integration of inexpensive renewable or waste heating energy into the supply systems. From an economic point of view, relatively high price stability and be expected due to the use of locally available renewable, or surplus energy sources. It can be seen from a number of analyzed case studies / community developments that especially for new areas a district heating supply offers a very attractive way to supply heating energy, even to low energy or even passive houses. Most technical challenges on the grid and heat production side have been solved over the last years, but the integration of these ideas into the building stock, especially for existing buildings offers a lot of challenges, as there is the hygienic domestic hot water preparation in low temperature grids or the installation of low temperature room heating systems. The session should enable the exchange of knowledge and viewpoints form district heating and building technology experts with respect to overcome the technical barriers for a further development of this promising technology in the existing building stock. It is closely related to the joint research project within the frame of the international Energy Agency District Heating and Cooling program, the Annex TS1 on "Low Temperature District Heating for Future Energy Systems".

Presenters:

• Ann Van Eycken, ES-SO
• Anders Hall, ES-SO
• Per Sahlin, EQUA

Scope:

The impact of solar radiation on the heat and light balance of a room is profound and, consequently, shading devices, glass, and control strategy are the first things to consider in HVAC and daylight design. Unfortunately, doing this is easier said than done. Not only do you need models that capture the correct physics of modern glazing and shading, but these models must also interact with a room model that accounts for all the physical processes that come together in the final room heat and light balance. Naturally, one must have correct product data for all involved components and be able to describe control action that reflects real systems. Today, these systems may well couple artificial and natural daylight with the thermal state of the room. The workshop starts with a presentation of a new quality assured database for shading products under the auspices of ES-SO and continues with the introduction and demonstration of a new tool chain for the complex design task.

•  With adequate system design heat pumps are highly efficient, enabling a nearly zero energy balance with less on-site generation
•  Heat pumps can cover both heating and cooling needs with the same generator in multifunctional use
•  Heat pumps can convert surplus electricity of on-site generation to heating or cooling energy, offering demand response capability to the grid

In Annex 40 heat pump application in nZEB has been investigated in the nine participating countries CA, FI, DE, JP, NO, NL, SE, CH and US. The final workshop of IEA HPT Annex 40 will give an overview of the Annex 40 work and contributions of the participating countries regarding

•  State of nZEB definitions and implications on heat pump use
•  Results of case studies and efficient system solutions
•  Technology developments of heat pumps for nZEB
•  Field-monitored heat pump performance and optimization potentials

As conclusion perspectives on heat pump application in nZEB are given.

• Francesco Scuderi
• Morten Schmelzer
   

Scope:

By attending this Eurovent workshop, participants of CLIMA 2016 will learn…

• How to save energy by applying the best performing air curtains for their construction projects,
• Which ISO standards should be applied for measuring air curtain performances,
• How state-of-the-art air curtains can contribute to a healthier indoor environmental quality,
• All about the upcoming Eurovent rating standard for air curtains.

It makes sound economic sense to create an efficient and invisible door that keeps the cold and hot inside. Air curtains can be even more effective when used in air conditioned or cold storage buildings. Thermozone technology with its precisely adjusted air velocity gives even protection throughout the opening and contributes to a better indoor air quality. Effective air curtains provide an efficient separation with the lowest possible energy consumption, regardless of whether it is the heat or the cold that project engineers want to keep out. This Eurovent workshop provides for a hands-on introduction to state-of-the-art air curtain technology, allowing you to make valid choices concerning your building projects.

Three learning points:

1. How to reduce energy demands by applying highly efficient air curtains to construction projects (Return on Investment)

2. How to improve your buildings’ indoor air quality through state-of-the-art air curtain technology (health and safety)

3. How to choose the right air curtains for your system (size and installation)

Introduction to Intelligent Energy Europe project the "Total Concept" (Alireza Afshari)

Main steps of the Total Concept method implementation (Mari-Liis Maripuu)

The economic principles of the Total Concept method (Åsa Wahlström)

The Total Concept method implementation in the Nordic countries- outcomes and lessons learned (Mads Mysen)

Short description:

In order to reach the 20-20-20 EU-targets it will be essential to increase the ambitions by the building owner´s to carry out major energy refurbishment projects in the non-residential building sector. In existing non-residential buildings energy savings can often be achieved by improving the building envelope and the performance of HVAC systems and other energy requiring installations. In addition, changes in user behavior can be effective - without loss of comfort. However, if the measures are to be carried out in practice then they would have to comply with the property owner’s or client’s terms and conditions for long–term investments. Total Concept offers a method and a economic tool that can provide the information required by establishing a platform for decisions on investments in energy-saving measures. The method applies a refined systematic approach to the work with energy issues in buildings, with the aim of achieving maximum energy savings in a cost efficient way and to motivate building owners to take a step further and make decisions on larger investments. A European cooperative venture has been established, involving Sweden, Norway, Finland, Estonia and Denmark, to further develop the method and to test the concept in the various national contexts. The aim is to establish a reliable market driver for major renovation projects that can lead to considerable energy savings in the building sector. Since the non-technical barriers influencing the renovation rates can be somewhat similar also in other European countries, it will be possible to transfer the method also to other countries. The workshop covers the identified main non-technical barriers in the renovation market in northern European countries and how the Total Concept method could be a solution to overcome these barriers. The results of Total Concept method implementation in the Nordic countries are presented and possibilities for increasing the number of larger energy renovations of non-residential buildings will be discussed.

Organiser: IEA EBC Annex 66: "Definition and Simulation of Occupant Behavior in Buildings"

www.annex66.org  

Speakers:

Andreas Wagner (KIT, Germany): Experimental approaches for collecting occupant behavior data in the field and in the lab

Ardeshir Mahdavi (TU Vienna, Austria): New modeling approaches and quality assessment for occupant behavior models

Rune Andersen (DTU, Denmark): Application of occupant behavior models in building energy performance simulation for improved design and operation of buildings

Short description:

Occupancy behavior in buildings is of growing importance for building design as well as for building operation and performance optimization, as it turned out to be one of the leading influences on energy consumption in buildings. Occupancy behaviors are either random, or purpose-driven (e.g. entering/leaving a room, consuming domestic hot water, using an appliance) or comfort-related (e.g. adjusting a thermostat, opening a window for ventilation, closing blinds). They change the indoor environment in terms of temperature, humidity, illuminance levels, air quality etc. which influences total energy consumption of a building. As building services systems and their controls are becoming more complex and sophisticated, occupants are often not aware of the relation between their actions and their influence on energy consumption.

The challenges to model and predict occupancy behavior in buildings are: (a) occupancy behavior is stochastic and complex in nature; (b) monitoring occupancy behavior relies on various sensors with relatively high costs; and (c) privacy issues make data collection difficult. Hence, there is a lack of consistent data from real-life building operation and therefore state-of-the-art models used in the planning practice simplify user-related actions and mostly underestimate their impacts. There is a strong need for improved and more accurate approaches of modeling occupant behavior as well as for integrating these models into building simulation programs in order to support planners and building managers during the design phase and building operation.

This issue has been raised in the IEA Annex 66 Definition and Simulation of Occupant Behavior in Building and researchers contribute to different tasks and activities in this context since the beginning of 2014. The workshop will introduce into three major areas of the Annex work in order to open discussions between researchers and practitioners about the necessity and the best strategy to implement occupant behavior in building design and operation.
