Susie and Claire give their feedback on attending (and presenting papers at) the 2024 CIBSE Technical Symposium in Cardiff.

Automation opens up huge potential to make modelling software work harder so that I can focus my attention on the tasks that need a human brain – getting the initial model creation right, and interpreting the results.

Does everybody need good NABERS?
The National Australian Built Environment Rating System (NABERS) has proved itself effective at significantly improving in-use energy performance in (initially mostly office) buildings in the Australian market, and is now being introduced to the UK.
CIBSE have recently published TM57 Integrated School Design. This document covers various design aspects for schools such as thermal comfort, acoustics, daylighting, air quality and ventilation. It states: “Teaching and learning spaces pose a great challenge to designers and engineers as the environmental needs are more complex than with most rooms. The challenge
Inkling is working with a number of partners, including lead assessors, designers and installers, in order to provide a full package of ESOS compliance services. Our team has the depth of experience, skills and knowledge to ensure your ESOS audit will be carried out efficiently while meeting the complex compliance requirements laid down by
Overheating in buildings has historically been quantified by the number of occupied hours per year that the indoor temperature exceeds a particular temperature, irrespective of external temperatures. However, recent research has shown that comfortable room temperature changes with the external air temperature meaning that occupants are comfortable with higher room temperatures during warm weather. This
The “Performance Gap” – the difference between design predictions and operational energy use – is a serious issue for our industry. The CarbonBuzz web site shows that many buildings consume between 1.5 and 2.5 times the predicted design energy. In order to address this, the industry needs both better energy-use predictions and a greater
Following on from our first (sell-out) training day on predicting in-use energy performance (in association with Colin Lillicrap): http://www.colinlillicrapassociates.co.uk/8.html which took place on 7th May (the next date with places still available is 4th June – follow the link to book); we are now working with Sarah Davis at Skills4Stem to develop further #BuildingPhysics related training sessions
The Notional Building To assess carbon compliance with the Part L 2013 building regulations, the building as designed is entered into modelling software and compared to a baseline building known as the ‘Notional’ building. The Notional building is defined by the rules in the NCM modelling guide (for buildings other than dwellings). The following
Part L2A 2013 The Building Regulations Approved Document Part L2A 2013 for non-domestic buildings have recently been released. These regulations come into force in England on 6th April 2014. Separate rules apply to Wales, Scotland and Northern Ireland. Transitional arrangements will apply and these are the same as for the 2010 regulations update
There has been a lot of discussion in recent months concerning ‘The Building Performance Gap’. However, on closer inspection it actually turns out that there are many different types of Building Performance Gap. These are caused by a wide spectrum of conceptual and quality issues ranging from a lack of clarity in the industry regarding
