RSK Building envelope performance – Invitation to RSK’s breakfast briefing

Introduction

Over the past 20 years, there has been much focus on developing nondestructive methods for assessing the performance of building fabric, including air permeability, infrared thermography and acoustic sound insulation testing. RSK has been at the forefront of this movement and, while undertaking testing work, has developed a range of design consultancy services to help its clients to achieve the required performance standards.

RSK’s breakfast briefing will provide an overview of the building fabric issues to consider; the implications of not getting things right (failure and litigation); when and how they should be considered for maximum effect; and the integrated service RSK can provide to help inform the process. The means of achieving the performance requirements of the future have moved from being reactionary construction-based retrofits or more recently on-site post design conundrums to being upfront engineering- and design-led solutions.

Why you should attend

The upper limiting values for many of the parameters for building fabric performance, as determined using SAP or SBEM calculations, have remained fairly static. However, the overall target for carbon dioxide production from buildings has fallen and this consequently reduces the allowable targets.

Until now, the three fundamental fabric considerations, airtightness, insulation continuity and vapour control, have tended to be considered in isolation. However, improvements in one without considering the consequences for the others can cause further complications, including poor ventilation, the risk of condensation and lower occupant comfort levels. The noticeable effects of these failures are exacerbated as the overall building performance improves.

RSK is seeing an increase in the number of complaints from building owners and tenants regarding building fabric performance and comfort. Typical complaints are surface condensation and mould growth, draughts, overheating, excessive heating bills, water ingress (possible evidence of interstitial condensation) and structural failure or early degradation of the fabric thermal elements.

Knowledge among stakeholders in construction projects about fabric performance is growing. Unless these issues are considered holistically, the difference between the desired performance and that which is achieved will widen and post-completion claims will increase.

The next challenge in building fabric performance will be delivering buildings with consistently low air permeability (<3), while providing adequate insulation continuity, vapour control, weather tightness, acoustics and longevity for the proposed design.

Who should attend

Our seminar is aimed at architects, engineering designers, design managers, construction managers, estimators and cost managers, together with property developers and owners.

CPD

This seminar counts for one and a half hours of continuing professional development time, so delegates will receive personalised certificates after the seminar. For more information, please contact Natasha Layal.

Guest speaker

Aleksandra (Sasha) Njagulj, head of sustainability and innovation at Bouygues UK

Aleksandra is a qualified architect with over 15 years’ practical experience in architectural design, design management and the sustainable built environment. In 2009, she joined the UK subsidiary of Bouygues Construction, a large international construction company, initially as a design coordinator working on various school projects before moving within the organisation to pursue her passion for sustainability. She currently leads the Sustainability Hub, an enthusiastic team of in-house experts within the technical department and at the forefront of the company’s commitment to deliver true sustainability for its clients. Aleksandra is also in charge of research and development and innovation projects, and always on the lookout for new build environment techniques, products and tools, and joins the academic and industrial partners in their development.

Aleksandra has an MSc in architectural design from the University of Belgrade, Serbia, and an MA in interior design from the University of Westminster, London, UK. She is currently studying for an MSt in sustainability leadership at University of Cambridge, UK. During her time with Bouygues, she has supplemented her architectural qualifications by becoming a licensed BREEAM and Code for Sustainable Homes Assessor and a BREEAM Accredited Professional.
