Start the BREEAM process as early as possible. It makes achieving sustainability targets easier and cheaper than leaving it later.


Currently the most prominent sustainability assessment and certification process in the UK is the Building Research Establishment Environmental Assessment Method (BREEAM), with other standards, such as the WELL Building Standard, beginning to penetrate the market. So, is BREEAM assessing the factors that matter most, and how applicable and relevant is it to all buildings? Launched in 1990, BREEAM is the industry norm in the UK and has been used to demonstrate the sustainability credentials for over half a million buildings which have been assessed and […]

Is the Well Building Standard worth the investment?

Sustainability, energy efficiency and wellbeing indicate the quality of a building. Is now the time to consider the return on investment of implementing the Well Building Standard? Wellbeing, as much as energy efficiency and carbon reduction, is becoming a key criteria against which a building’s quality is judged. We spend over 90% of our lives in and around buildings, where the concepts of sustainability and environmental impact are widely understood and measured. Now, consideration of buildings’ impact on occupants’ wellbeing – and productivity and absenteeism […]

An insight into the significance of thermal bridging analysis


by Chris Hocknell, Technical Director, Eight Associates It’s still relatively uncommon for building designers to commission thermal bridging analysis, despite significant benefits where this is undertaken early in a project. Attractively for developers, thermal bridging analysis can lead to a reduction in external wall insulation thickness, adding to the overall available floor area of a scheme. In addition, confirmation of reduced thermal bridging can shore up a project’s costs and timescales, and prevent the need for last-minute addition of further thermal insulation or improved air […]

Great Crested Newt (GCN) survey season opens – and new approach to GCN licensing in development


The Great Crested Newt (GCN) survey season runs from mid-March to mid-June. Great crested newts are rare across Europe and are protected by law, meaning that disturbance or damage to the newts or their habitat requires a European protected species licence.  Projects with sites that contain a pond or are located within 500m of one, may require a GCN survey – and missing the survey window will cause lengthy delays.

Air tightness: Design insight, build tight, ventilate right


The importance of considering air permeability at the early design stage The air permeability of the building envelope underlies the potential energy efficiency of a building, as poor airtightness can be responsible for up to 40% of heat loss from buildings. The level of air permeability is determined by the standards of design, materials, and workmanship. Well-managed, it enables lower running costs; prevents uncomfortable drafts and minimises condensation risks.  If overlooked at the early design stage, it can lead to underperforming buildings that, at worst, […]

In the UK, certain wildlife is protected by legislation which makes it illegal to kill, injure, capture or disturb the species in question.  Conducting a survey of the habitat is essential to gain planning consent, and finding potential for these species on site during a project can mean work has to stop at once. Breaking the law could result in a fine of £5000, up to six months in prison and serious reputational damage.   It’s vital to plan accordingly; there are only certain times of […]

It’s against the law to harm bats or their habitats. Do you know how – and when – to spot the potential for bats on site?

Eight Associates Ecologists can help if you require a bat detector survey or advice about a protected species. Read our case study or give us a call to talk through your requirements. In the UK, all bat species are protected by the Wildlife & Countryside Act (1981) as amended, Countryside and Rights of Way Act (2000) and the Conservation of Habitats and Species Regulations (2010). It is illegal to deliberately or recklessly kill, injure, capture or disturb bats, obstruct access to bat roosts or damage […]

Education sector case study: the positive impact of using skylights in the classroom  


In the education sector, studies have shown that daylight quality and levels have a positive effect on students’ performance. So, as skylights increase the amount and improve the quality of daylight that a space receives, the question arises, could students’ performance be enhanced through the integration of skylights in schools? The study below was conducted in Denmark – the findings are transferable to the UK, to any classroom or workspace. Please get in touch if you wold like more details of the study or have […]

Why could 25% of London’s land be covered with trees by 2025?

‘A society grows great when old men plant trees whose shade they know they shall never sit in’ – Greek Proverb Eight Associates now provides BS5837:2012 Tree Surveys, Arboricultural impact Assessments, Arboricultural Method Statement and Arboricultural Clerk of Works. Valuable trees on a development site are not a hurdle to be overcome – early valuation could mean both a smoother journey through planning and an enlarged design which adapts to trees in close proximity.

What is thermal bridging and why does thermal bridging analysis matter?


Thermal bridges are ‘weak spots’ which occur where there is a break in the continuity of, or penetration through, the insulation in a building envelope. Thermal bridging is heat loss at a junction between two thermal elements. The benefits of thermal bridging analysis are wide-ranging and applicable to building owners, developers, occupants and design teams. It’s more than avoiding ‘cold bridges’ – it is a systematic heat loss analysis and subsequent design refinement approach that can maximise available floor space, reduce the build cost and […]

How can living roofs reduce initial project and ongoing costs?


The most commonly associated benefit of living roofs is biodiversity. Yet living roofs save money –both in upfront and ongoing costs. A living roof is the easiest way to contribute to maximum BREEAM credits for land use and ecology, and it can be the only way of demonstrating an increase in ecological value post development if there is no soft landscaping on the ground. Living roofs provide comprehensive rainwater runoff management, improve energy efficiency by reducing  temperature fluctuations, and reduce heat loss and energy consumption by adding mass.  The installation cost of […]
