Stride Treglown achieves BREEAM’s highest rating at design stage

Stride Treglown's new Cardiff office has been awarded the UK's highest BREEAM Outstanding rating at design stage of 89.12%. The site has been acquired and construction has started with completion by April 2010.

The building has been designed to accommodate over 50 staff on two floors in an open plan studio arrangement linked by an open tread staircase. The 500sqm building will breathe new life into a former industrial development, which is being redeveloped into offices. It is located on a former industrial service yard that will also become the shared parking area for this office and the nearby NSPCC offices (also designed by Stride Treglown and due to be open in December 2009).

The wedge shape design responds to its orientation and site entrance arrangement, whilst the building's section and materiality respond to the desire for an exemplar building in sustainability, minimising energy consumption, waste and providing renewables on site. 

It has achieved a Grade A Energy Performance Certificate rating of 22 and its predicted emissions are just 14.2kgCO2/m2per annum. This is a reduction of 55% of the target emissions allowed for under the Building Regulations (31.7kgCO2/mper annum) achieved using a wood pellet biomass boiler for space and water heating and a small array of roof mounted photovoltaics.

Energy efficiency is aided by the adoption of a natural ventilation strategy using bms actuated windows in the walls and roof, providing fresh air during the day and cooling at night.

With an anticipated annual energy load of 18.3MWh/annum for space and water heating, annual running costs for the biomass boiler are anticipated to be as little as £700.  Water usage will be minimised with the adoption of spray fittings, low water use showers and wc's and ‘grey water' recycling for toilets. The Contractor is required to agree to a strict Waste Management policy, minimising waste or recycling as much as possible as well as achieving a Considerate Constructors score of 36 or more.

The site is within 200 metres of a bus stop. Cycle spaces, shower and drying facilities are included for cyclists and activity pursuits.  Car share parking spaces are given priority and in total the provision is lower than normal standards.

BRE Green Guide Grade A or A+ materials and forms of construction are being used throughout.   

Gareth Davies, director of Stride Treglown said, "We have been seeking new offices for some time and our Board challenged me to deliver a new office building in Cardiff that represented our approach to high quality design, was affordable and achieved the highest sustainability rating available.  It has taken a long time but it is a testament to the Stride Treglown Group's stability that our plans to build our own Cardiff offices are now being realised.   The development is being funded through RBS; we own the land and now that building has started on site, it is with real pride that we can say that we have the best design, the best team and a fantastic future in Wales".

Jane Davidson, Welsh Assembly Minister for Environment, Sustainability and Housing has supported our investment in sustainability, saying,

"This building is exciting in that it shows the direction we are travelling. It is energy efficient, uses natural ventilation and re-uses water. In other words it is sustainable and represents the future of new buildings across Wales.

"Earlier this year we launched our sustainable development scheme which will see the Assembly Government using all its devolved powers to make Wales truly sustainable in every way, from how we manage the environment to how we develop the economy.  The built environment will play a crucial part in this, as it is the largest contributor to greenhouse gasses in Wales. The way in which we construct our homes and buildings accounts for 40 per cent of our total carbon emissions. Buildings like this are a clear response to the need to act and provide the examples others can follow."
