Workshops and Result Seminar
Result seminar – B2RECoM
Introduction to the project
Globally, renewable electricity generation is rapidly increasing, when we want to get rid of fossil energy. New electricity generation mainly consists of wind and solar power plants. Increasing renewable generation has effects on the availability and price of electricity. Bottlenecks have already been observed in adding generation facilities to the main grid and the effects of fluctuating production on electricity price variations. A big challenge for the future is to increase the flexibility potential of the existing consumption system, in which case it would be possible to respond better than at present to fluctuations in generation. In this project, the potential of buildings to operate on fluctuating wind and solar electricity is investigated. The energy flexibility potential of buildings is examined as a whole, both in individual buildings and in energy communities. The research considers the potential of building structures to function as heat storage, the function of technical equipment in them as flexible loads, the importance of separate energy storage in buildings and the buildings’ own energy production. In addition to this, the potential of water electrolysis plants to operate in the generation of district heat, where the waste heat produced by them is utilized, is being investigated.Participants

Workshop – Building Simulations Teaching
Introduction to the Workshop
Surprise to none, building simulation (BS) is the very foundation of today’s design process: BS are needed at all phases, starting from predesign and building permits through operational phase up to renovations. They include estimations on heating and cooling loads, equipment sizing, control schemes, energy consumption, CO2 and cost calculations, optimization, option comparisons, energy certification – just to name a few tasks.
In our days, “energy modeler” is a recognized specialist position in HVAC, construction and building energy service companies. However, the traditional university education (scientific or applied science) cannot offer much training on cutting-edge simulation use cases to new entry level professionals. The teachers need to establish a hierarchy of studies starting from the basics, possibly until specialized student projects, within truly limited preparation time and resources. Active work-life expectations on the modeling skills are constantly changing: education shall attempt at least to follow upon the change.
This workshop aims to assist the educators to identify and showcase a solution to across-the-board problems such as material production, sharing and enhancement through demonstration of the Nordic teaching efforts and achievements, with invited educators to present best practice examples.

Workshop: IDA ICE demo - simulation possibilities of a versatile building energy software
Introduction to the Workshop
IDA ICE is a renowned simulation tool in the building energy field, particularly popular in Europe. It is known of its uncompromising component modeling quality and interconnectivity, result outputs and logging abundance, data post-processing options, simulation event traceability and a high accuracy of details in inputs and outputs. It is also notoriously complex: modeling in ICE requires a substantial level of experience and practice. The increasing available result types however reward the learning efforts: outputs are provided from the primary level (such as design day and overheating, annual and custom time energy simulations) to more sophisticated and specialized results (such as tailored plants, controls, renewable energy integration, borehole fields, multi-objective optimization, daylight, CFD, stratification zone model, systems co-simulation etc). In this workshop, EQUA illustrates the most significant simulation possibilities that any engineer, educator, real estate developer and interested party can draw some inspiration from.

Workshop: Design Projects Case Study Presentations: Bridging into Consultancy
Introduction to the Workshop
Consultancy in the building simulation field is a main actor: it drives all the sustainability-driven scientific research, pilot projects and innovations to find their ways into real-life completion. Academia leads the research and reveals the direction of future development: energy efficiency development, design and cost optimization, embodied and lifetime-emitted CO2 decrease, balanced thermal comfort and others.
Additional new trends are expected to prevail: a massive PV and renewables integration, both electric and thermal peak shaving-load shifting, short- and long-term energy storage options, demand response, energy circulation. Building simulation tools need to be able to back, follow and perhaps even foresee the directions.
The bridge between education and consultancy should be seen as a dynamic two-way street: future professionals need to know what kind of skills are required after leaving the school bench and the industry must attract new talent to execute the upcoming projects. What are the most efficient ways for both parties to navigate on this way? What kind of readiness is needed? What level of skills, specialization, field of interest and expertise are appreciated and expected?
In this workshop, we aim to introduce some of these forthcoming concepts in research incorporated into outstanding projects that were sculpted and secured by building simulations. These examples underline the importance of properly trained consultants that are aware of the trends and can deliver by using simulation software. Our attempt is giving inspiration both for future professionals and consultant companies to ensure a permanently tight co-operation between.
