WELL Building Standard The International WELL Building Institute launched the WELL Building Standard version 1 in 2014.

Grounded on medical research, the WELL Building Standard (WELL) is a performance-based system for measuring, certifying and monitoring features of the built environment that impact on human health and well-being. Today there are now 109 certified WELL projects and 840 WELL registered projects worldwide.

In May 2018, the WELL version 2 (v2) pilot was launched, this is the next version of the pioneering WELL Building Standard.  The WELL v2 standard presents a set of requirements for ten relevant factors, or Concepts; Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind and Community.  Placing people’s well-being at the heart of design and construction can enhance their health and experience, generate savings in medical and productivity costs, and so add value to real estate assets.

AES Sustainability Consultants, are pleased to announce that BREEAM Consultant Yasmin Spain is a qualified WELL AP (Accredited Professional) and will enable us to offer the WELL AP project role in addition to our BREEAM Services in a commercially viable manor.

Upcoming changes to SAP and Part L – What we know so far…

You may be aware that there is some discussion in the industry relating to an update to the energy assessment procedure for residential developments, generally referred to as SAP10, or SAP2018.

  It’s important to note that until the final document is published – which we expect to be sometime this summer – we only have the government response to the SAP consultation to guide us as to what this may look like. Following this, a consultation on changes to Part L itself can be expected towards the end of the year, which may introduce further and potentially more wide-ranging changes to be adopted in 2019.

At this stage, it appears there will be a number of minor technical amendments to SAP, as well as some more substantial changes which could have an impact on your current strategy for Part L1A 2013 compliance.

Some of these changes are likely to bring improvements in assessed performance, however the majority may make it more challenging to achieve compliance;

  • Changes to carbon emissions factors, the most significant of which is a reduction in the emissions from electricity of around 23%, to reflect progress that has been made in decarbonising the National Grid. This is likely to make electric heating systems more viable, however conversely would reduce the benefit from PV systems currently used to meet carbon reduction targets, leading to larger systems being required.
  • Changes to the assessment of thermal bridging, to remove the use of the ‘approved’ values associated with using Accredited Construction Details (ACDs) and worsen the default values. For many clients, we already mitigate this impact through ensuring that all your main building junctions are thermally modelled. We can calculate these on a one-off basis, or build a full library based on your standard detailing to use on future projects.
  • A more accurate assessment of hot water consumption would require us to account for the energy consumption and emissions from electric showers – which are overlooked in the current methodology – as well as more accurately reflect the design flow rates.
  AES are involved with various industry groups which guide and discuss this area of the Building Regulations, so we’re keeping abreast of developments and will provide an update when we have more definitive news. There may also be other changes in the future relating to compliance and enforcement, which are expected to now be on the agenda following the conclusion of the Hackitt Review – again, you’ll know when we know.

Please get in touch if you’d like to discuss any of the above, or anything you’ve heard on the grapevine in relation to the changes. As soon as any final documentation is published, the team at AES will analyse the impacts and publish a further newsletter to advise you of any implications.

As always, we will work with you to find value-engineered solutions that work for your business.

Lunchtime CPD: ISO Energy

“The CPD was useful. For example, we learnt about bolt-on renewable technologies from an installer’s perspective.”

Calum of ISO Energy recently provided our consultants with their June lunchtime CPD (Continuing Professional Development). 

When the consultants apply these renewable technologies in SAP they will have more of an understanding of the feasibility and the practical implications. For example, they learnt that if a ground source heat pump (which is too big) is installed, it can lead to the ground freezing!

Learning of the maintenance and payback costs for renewable technologies provided the consultants with a more holistic view, including the experience of these technologies at post-construction stage.

Calum of ISO Energy 

“It was interesting to learn of new lesser known technologies – e.g.heat exchanges in rivers and small-scale hydro.” 

“I now have more of an idea of a homeowner’s perspective – payback periods and RHI” 

” I learnt the impacts associated with sizing renewable technologies and installing correctly to ensure efficiency (including what happens when it goes wrong).”

” I now have someone to contact with questions regarding practicality.”

Would you like to provide our consultants with a lunchtime CPD? Please Contact us here to arrange.

Learning the ropes – Jonathan’s Sailing Day

We understand the importance of client relations and the benefits it can bring to our consultants personal and professional development.

When Jonathan, one of our Sustainability Consultants, was recently asked if he could join our client on their Company Sailing Day, we didn’t hesitate to approve.

The day provided Jonathan with the opportunity to explore the waters around Dorset, meet other industry professionals in a neutral environment and get to know our client a little better.

We are very grateful to all of our generous clients that have invited our consultants to partake in many wonderful character building opportunities over the years.
