Looking at a new approach for determining indoor environmental quality (IEQ) factors and their effects upon building occupants, BSRIA has provided the University of Reading’s School of Construction Management and the Technologies for Sustainable Built Environments (TSBE) Centre access to their Bracknell office building known as the “blue building”.

 IEQ factors are proven to affect occupant well-being and business performance, however, for the first time, actual environmental and physiological field measurements will be compared. New research therefore has been developed by the University of Reading, which will seek to understand these relationships and the potential impacts of known IEQ factors on perceived levels of occupant satisfaction and well-being.

Understanding fundamentally how IEQ factors can affect building users, will allow system designers to finally visualise occupant well-being, personal satisfaction and productivity as part of a holistic business performance model. Based upon empirical measured IEQ factors and surveyed occupant data, the research hypothesis proposes that high-density occupation can reduce office workplace environmental footprints significantly when physiological impacts are understood.

The research methodology brings together measured environmental characteristics, physiological performance measurements, POE survey responses, and then uses an Analytic Hierarchy Process (AHP) to assess existing workplace designs.

The research, therefore, will provide empirical data to create informed business decisions focused upon these challenges. This is done by increasing the importance of well-being and by defining performance as a key metric.

Field research is currently underway on the top floor within the “blue building”, where 4 willing volunteers are participating in physiological sensory measurements and POE response surveys. The project will be running for 12-months, with the initial current 2-week data acquisition period being repeated a further 3 times during winter, spring and summer of 2015/16.

The research is also being conducted at two other similar office environments in Manchester and London, and seeks to support the hypothesis that hi-density workplaces are a further sustainable step in designing and operating more efficient and effective intelligent buildings.

The Building Services/Engineering ‘BIM Readiness’ Survey

BECA_strapSRIA is delighted to be supporting a sector-wide BIM survey which has been launched by the Electrical Contractors’ Association (ECA), alongside the Chartered Institution of Building Services Engineers (CIBSE) and Building, the UK’s leading magazine for construction professionals.

The new study will explore the readiness of the building services sector to engage with BIM within the next six to 12 months. The survey is also supported by other leading players in the sector, including the British Electrotechnical and Allied Manufacturers’ Association (BEAMA).

The investigation is expected to reveal crucial information about how prepared the sector is to adopt ‘BIM Level 2’ practice, noting the government requirement for BIM Level 2 engagement with centrally procured contracts during 2016.

BSRIA’s Principal Consultant and BIM specialist, John Sands, commented:

“With the implementation of the UK Government’s Level 2 BIM mandate just a few months away, the building services industry should be in a position to make the most of the opportunities it will present. This survey will help us all to identify where we are in the BIM journey, and to enable us to plan the way forward to BIM maturity.”

ECA Director of Business Services, Paul Reeve, said:

“This sector-wide survey will provide much needed and very timely information on how ready the building services sector is to engage with BIM as we approach the 2016 government deadline.

We urge all building services companies to take part in the new survey, and we will be sharing the data with the industry, the Government and other stakeholders when the results are in during September 2015.”

CIBSE Technical Director, Hywel Davies, added:

“Government is committed to using BIM to improve its management and operation of buildings and infrastructure. Mechanical, electrical and plumbing services are all critical to the effective operation of buildings. Our sector is involved in the operational life and performance of built assets, not just the design and delivery. This survey is important for our sector to understand how well prepared we are for BIM.”

The BIM study will run until September 15.

More information about BIM (Building Information Modelling)

• ‘Level 2 BIM’ is the process of working with digital building information, including data-rich objects, which can be effectively shared between those who are building and/or maintaining the building and its services. This is ‘collaborative 3D BIM’ and it involves using tools such as COBie, BS/PAS 1192, ‘Soft Landings’ and various BIM Protocols.

• The Government aims to require collaborative 3D BIM on its centrally procured projects by spring 2016 (BIM Level 2), in order to unlock innovation and benefits throughout the building project life-cycle, including cost savings.
