The Missing Link
The missing link: Why HVAC controls in a building are critical to efficiency, how, if understood correctly, they can reduce the operational energy consumption of existing buildings by 20-40% and why they (and HVAC modelling) are the key to narrowing the performance gap.

Weather Files in Building Performance Simulation
With growing concerns over the progressive impacts of climate change, access to appropriate, high quality weather data is an increasingly important consideration for building performance modellers.In this webinar we are joined by Nishesh Jain and Sukumar Natarajan who will be presenting on the topics “Right weather for the right modelling application: What, How and Where?” and “Localising weather and long-term resilience” respectively.

Teaching the fundamentals of building performance simulation
Building performance simulation (BPS) tools employ a large number of mathematical models to simulate a building’s performance under a given set of weather and operating conditions. Many aspects of performance can be appraised, including energy consumption, ventilation effectiveness, thermal comfort, lighting quality, etc. The objective is to represent the significant physical processes so that the simulation provides an accurate—or at least a useful—representation of reality.

Can modelling be used to educate architects?
For David, one big question is, given that Passivhaus and other low energy possibilities exist, why do new buildings tend to use just as much energy as old ones? Although many seem able to list possibilities, this is very different to evidence. Particularly when we try to put numbers to the fraction each possibly plays, from poor contracts, lack of ambition to poor engineering. One of the lessons from the Passivhaus movement is that for a low energy design, one needs to start in the right place on day one. This indicates that the architect and the client need to rapidly agree on an evidence-based form, fabric and philosophy that will several years later lead to a near energy neutral building.

ESTIMATING AIRBORNE INFECTION THROUGH SIMULATION AND ANALYSIS
Recent wider acceptance of far-field being a significant, if not primary in some circumstances, transmission route for SARS-CoV-2 has thrown a late focus on how the ventilation design and operation of our buildings might support a reduction in infection rates. We have speakers from academia and industry discussing some of the simulation and analysis tools and methods used to understand airborne infection in the built environment and some of the latest research programmes that have been designed to further improve our understanding and applications.

BEYOND COP26: THE ROLE OF BPS TOWARDS CLIMATE RESILIENT BUILDING DESIGN
This webinar will explore building performance simulation methods, tools and datasets that could be employed to assess the impact of climate change on building performance, with a focus on indoor environmental conditions and energy use, and the optimisation of climate change adaptation solutions.

ESTIMATING AIRBORNE INFECTION THROUGH SIMULATION AND ANALYSIS – PART 2
This part 2 of the joint event by IBPSA-England and CIBSE Building Simulation Group will present some of the latest knowledge and developments in this area with speakers from academia and industry discussing some of the simulation and analysis tools and methods used to understand airborne infection in the built environment and some of the latest research programmes that have been designed to further improve our understanding and applications.

DIGITAL TWINNING IN BUILT ENVIRONMENT
Digital Twin technology is an emerging concept that has become the centre of attention for industry and, in more recent years, academia. The Digital Twin is defined extensively but is best described as the effortless integration of data between a physical and virtual machine in either direction. It can tackle the challenge of seamless integration between IoT and data analytics through the creation of a connected physical and virtual twin. This webinar will present some of the latest knowledge and developments in this area with speakers from academia and industry discussing the role of Digital Twinning in the built environment.

NON-DOMESTIC HEAT PUMPS
Heat pumps have an important role in decarbonising in both domestic and non-domestic contexts. This joint IBPSA-England, CIBSE Building Simulation Group and CIBSE HVAC Group webinar focus on Heat Pumps in Non-Domestic Context. Program:
