AMBS – Doing Our Bit For A Greener Environment

Over the years, we have become increasingly aware of the environmental impact that construction and renovation can have, and we are encouraging our clients to allow us to use eco-friendly materials as widely as possible.

In some cases, there is a small premium to pay, but in other instances, we are prepared to subsidise the additional cost in order to minimise the effects of our work on our planet.

We also make strenuous efforts to ensure that any materials we take off site are recycled wherever feasible.

This month, our feature article is taken from the GREENSPEC website, and looks at the relationship between coniferous forests and climate change. We hope you find it interesting…

 

Coniferous forests and Climate Change

2 strands of research have emerged recently that suggest two contrary mechanisms in the way coniferous forests contribute to the climate change equation.
 

Solar radiation absorption

•    It is estimated byLaboratoire des Sciences du Climat et de l'Environnement that Europe's summertemperatures have increased by up to 0.12 C since 1750 owing to changes in forest planting.

•    Over the last 150 yearsforests have been planted out with the faster growing conifers used inconstruction at the expense of less commercially viable broadleaf species.

•    European forests now cover 10% more land than before the industrial revolution.

•    Conifers like spruce and pineare darker and absorb more solar radiation than species such as oak and birch. Lighter leaves reflect more radiation back into space (the 'Albedo effect').

•    Modern managed forests also absorbless carbon than the naturally growing forests pre-1750.  This is because modern techniques of harvesting trees release carbon that would otherwise be stored amongst forest litter, dead wood and soil.
  

Solar radiation reflection

Aerosols are minute particles suspended in the atmosphere. When these particles are sufficiently large, we notice their presence as they scatter and absorb sunlight. Their scattering of sunlight can reduce visibility (haze) and redden sunrises and sunsets.

Aerosols interact both directly and indirectly with the Earth's radiation budget and climate. As a direct effect, the aerosols scatter sunlight directly back into space. (Nasa)

Forests emit large quantities of volatile organic compounds (VOCs) to the atmosphere. Their condensable oxidation products can form a secondary organic aerosol which then becomes a significant and ubiquitous component of atmospheric aerosol. Research published in Nature (27-2-1016) shows the chemical processes by which several VOCs, such as monterpenes, from pine forests form particles that grow from just one nanometre in size to 100 nanometres in about a day. These airborne solid or liquid particles can reflect sunlight, and at 100 nanometers they are large enough to condense water vapor and prompt cloud formation.

Boreal or coniferous forests give off the largest amount of these compounds, so the finding is especially relevant for the northern parts of North America, Europe and Russia.

We’re Doing Our Best To Eradicate Plastic Use, But We All Need To Do More

Thanks to the efforts of David Attenborough, Greenpeace and the like, we’ve all become acutely aware of the impact plastics are having on our planet.And here at AMBS, we really are trying to do our bit, by banning all throw-away plastic from our construction sites in St Albans and Harpenden.

Cement’s carbon footprint, and alternatives we can use

The worldwide cement market is booming due to the demands of urban construction, but the massive levels of carbon it uses has been fuelling research into environmentally-friendly alternatives to cement.

The differences between traditional and eco-friendly building techniques

There has been much debate in the construction industry recently regarding the merit of eco-friendly building and construction methods, compared to ‘the old ways’, and there’s no doubt that there is an unstoppable momentum in favour of new ways.
