Environmental Chamber

Environmental Chamber

The Building Research Park welcomes the addition of a 4x8m Environmental Chamber funded by the EPSRC. This giant chamber can mimic the environment through controlled simulations and allow evaluation of large scale construction material under weather conditions. By introducing a panel, the chamber creates a sandwich which simulates the indoor condition on one side of the construction material and external conditions on the other side. Weather conditions such as extreme temperature, humidity, wind and rain can be simulated making the research at the park even more relevant. Not only can we see what happens in the real environment, but we can look at how predicted environmental pressures affect the world of construction material.

The Hive

Want to know more about the construction of the HIIVE facility? The Structural Engineer released this month shows the trials and tribulations of constructing this unique facility in the midst of an ex World War 2 military site. The exposure of the site to weather conditions may put the research materials through its paces, but the ultimate design of the facility needed some careful consideration to such a weather variant site.

Flood Resilence

📥  Civil Engineering, construction, HIVE, structural engineering

A recent BBC documentary shows that the work done at the University of Bath and specifically the Building Research Park are really starting to analyse the challenges of the future construction. With more and more demand on the space for housing and development the more we encroach upon the 'unusable' landscape. As much as many of us would like to prevent the need to build in flood plains, at the end of the day as a growing nation we all have to work and live somewhere. The question is do we know what to do if flooding occurs and what kind of infrastructure resilience do we expect? Looking at the existing timber housing stock is one way to understand what to do in the event that a flooding disaster occurs.

Construction Products of the Future

We have been mentioned again in two articles about the future of the energy industry. It becomes more apparent that it's no good just to be be finding more sustainable energy sources but to make sure that the buildings the energy sources supply are able to use the energy effectively and that the leaders of the future know about it.

Quoting for the IOM3 article "According to Innovate UK, 27% of UK carbon emissions come from domestic buildings (18% non-domestic), and 73% of these built environment emissions come from heating and the provision of hot water. "

"To achieve an 80% carbon reduction from a domestic home costs about £70,000, while an investment of about £10,000 will result in a 20–30% saving. This is an issue that Jones is investigating. ‘We have a project where we are retrofitting five houses in Wales and the main aim is to adopt a system approach, rather than an elemental approach, trying to combine the set of measures, which will give us some more cost effective approaches so we get 60%–70% savings in CO2 for about £25,000.’ "

Quoting from Edie "From teaching future engineers about renewable energy to finding innovative ways to reduce carbon emissions, universities can clearly play a huge part in the development of strategies for tackling global warming."

"Universities often collaborate with external organisations and are ideal 'research and development hubs' from which projects can be tested and improved. "

"University of Bath: HIVE building

In September a new £1m HIVE building was opened in the University of Bath's Building Research Park to test low-carbon sustainable building materials in realistic open-air conditions before being incorporated into buildings.

The building aims to tackle the fact that 50% of all UK emissions come from the construction industry, by offering a 'plug and play' facility to test and evaluate facades, walls and panels on their energy efficiency, flood resilience and structural capability."

Presentation and Tour to Constructing Excellence

Presentation and Tour to Constructing Excellence

The Building Research Park has welcomed tour and visits from Construction Associations since the opening including Constructing Excellence and the Zero Carbon Hub. The increasing awareness of the facility is providing real interest to a Construction industry striving to find ways to create low impact and sustainable infrastructure. These events are not only helping to promote the awareness of the Building Research Park but starting to bring questions from industry experts that need answers if the carbon targets are to be met. "What do we do with existing housing stock?" "How can we build more efficiently?" "Why does the product I specify not perform the way it should?"

The Building Research Park is offering the platform to allow construction researchers and specialists a solution to their research needs that will help answer these questions. Welcoming the research potential and enquiries that the facility is being brought, it is becoming clear that the need to find the real life realities and solutions to construction materials and technologies needs this flexible platform to get the answers.

Can we grow our way out of climate change?

Dr Mike Lawrence is Director of the University of Bath’s Building Research Park (BRP)– aimed at reducing the carbon footprint of buildings. The following blog appeared on the Guardian Sustainable Business website on 25 September 2014 to coincide with the launch of the BRP's opening.

The Hive

So how can growing buildings help with climate change, you may ask? Well, it’s all about renewables and ‘sequestered carbon’. The Department for Business, Innovation and Skill’s 2010 report on Low Carbon Construction concluded that construction was responsible for some 300 million tonnes of carbon dioxide (CO2­­) emissions, which is almost 47 per cent of the UK’s total emissions. Of this figure some 50 million tonnes is embodied into the fabric of buildings. It uses 1.46 tonnes of CO2 to make 1 tonne of steel and 198kg CO2 to make 1 tonne of reinforced concrete. One square metre of timber framed, hemp-lime wall (weighing 120kg), after allowing for the energy cost of transporting and assembling the materials actually stores 35.5kg of CO2.

If we can convert plants into building materials, we are in a win-win situation. Firstly, plants use the energy of the sun to convert atmospheric CO2 and water into hydrocarbons – the material that plants are made from. The plant acts as a carbon store, sequestering or ‘absorbing’ atmospheric CO2 for as long as the plant continues to exist. This CO2 is only re-released when the material is composted or burnt, and the great thing is that through replanting it you can re-absorb this CO2 annually, in the case of straw or hemp, or every decade or so in the case of timber, rather than the 300 million years that it takes to recycle coal or oil.

Secondly, plant based materials can be used to make high performing building envelopes, protecting against external weather and  making a building more comfortable, healthy and energy efficient to live in.

Not only can they be used as insulation materials, displacing oil-based alternatives such as polyurethane foam, but they also interact with the internal environment in a way that inorganic materials just can’t do. This is because they are ‘vapour active’. Insulating materials such as hemp-lime, hemp fibre and wood fibre are capable of adsorbing and releasing water vapour. This is doubly effective, because not only can they act as a buffer to humidity (taking moisture out of the air), but they also stabilise a building’s internal temperature much better through latent heat effects (energy consumed and released during evaporation and condensation within the pores of the material).

To build using hemp, the woody core or shiv of the industrial hemp plant is mixed with a specially developed lime-based binder. Factory-constructed panels are pre-dried and when assembled in a timber frame building, the hemp shiv traps air in the walls, providing a strong barrier to heat loss.  The hemp itself is porous, making the walls well insulated while the lime-based binder sticks together and protects the hemp, making the building material resistant to fire and decay. As the industrial hemp plant takes in carbon dioxide as it grows, and the lime render absorbs even more of the climate change gas, hemp-lime buildings have an extremely low carbon footprint.

In this way bio-based materials can be used to construct ‘zero carbon’ buildings, ie. buildings where the materials have absorbed more CO2 than is consumed during construction. By applying PassivHaus principles (the voluntary industry standard for low-carbon design) to bio-based buildings, a building’s energy use once inhabited can also be reduced to minimal levels. This is a true ‘fabric first’ approach, where the fabric of buildings passively manages energy consumption, rather that purely relying on renewables such as solar panels and ground source heating systems which have a more limited life-span and have the potential for failure.

I worked on a project recently for the Science Museum to reduce the high energy cost of archival storage. They needed to have large enclosures kept at a steady humidity and temperature to ensure that items ranging from the first edition of Newton’s Principia through to horse drawn carriages and even Daleks do not deteriorate. Normally this uses energy intensive air conditioning systems.

The three storey archival store that the Science Museum built in 2012 using a hemp-lime envelope was so effective that they switched off all heating, cooling, and humidity control for over a year, maintaining steadier conditions than in their traditionally equipped stores, reducing emissions while saving a huge amount of energy.

In the BRE Centre for Innovative Construction Materials (BRE CICM) at the University of Bath we are working on some very exciting EU funded projects to increase the use of low carbon construction solutions. Research programmes aimed at producing certified construction systems using straw bale and hemp-lime respectively have potential to transform the construction industry in the UK, introducing such revolutionary sustainable products to the mainstream sector.

Other research we are carrying out is finding better ways to passively improve the internal air quality of buildings by using improved bio-based materials to interact with air borne pollutants, removing them from the building.

The new HIVE building - a £1m project funded by the Engineering and Physical Sciences Research Council (EPSRC) - acts as a platform for research projects of this type. The HIVE also has a purpose built flood cell, which will support research into creating buildings and building materials which are more flood-resilient – a valuable resource in these times of climate change induced adverse weather conditions.

In practice what this all means is that the industry and government now need to embrace the opportunities presented by bio-based construction materials to reduce emissions. Good quality domestic housing can be built out of structural timber with a bio-based insulating envelope such as the ModCell® system using straw; the HempCell® system using hemp-lime, or other  systems using wood fibre or other cellulose fibres.

With domestic housing high on the Government agenda, surely it is time the construction industry recognised the economic and environmental benefits of bio-based construction materials and became less reliant on depleting resources such as oil and steel.

HIVE Investigators and Barnwood Construction Top Out

The HIVE celebrates a momentus occasion as the building nears completion. This long awaited project coming to fruition promotes the ability for future research into construction materials and technologies. The facility, once complete in a few weeks time, will reduce the lead time for protyping materials to get them to market. The facility also offers the opportunity to investigate theories of structural and material performance of novel products, providing more reliable modeling for future design and build projects.  Mike Lawrence, Principal Investigator of the HIVE project, celebrates with a toast to the future of construction research.

The topping out ceremony was attended by representatives from the University of Bath, Barnwood Construction Ltd and Science Museum Group, Swindon.  Media representatives from the Swindon Advertiser and Swindon Link were also shown the facility prior to the official opening in September. Swindon Business News and Building4Change also promoted the event.

The ceremony marks an achievement in the construction project that has been in planning from August 2013. The design team also consisting of Integral Engineering Design and DM3 architect have worked hard over the last few months to understand the complex requirements of this test facility and are now being to see the fruition of their work.
