Designing sustainable buildings doesn’t always mean hi-tech solutions. From green roofs to living walls to constructed wetlands, sometimes it’s just a matter of embracing natural solutions. Lenny Antonelli investigates the emerging technologies and designs that use nature to improve the performance of buildings.
Lime-hemp is developing as a bio composite construction material with serious ecological and energy advantages. Patrick Daly, lecturer in Environmental Design at DIT Bolton St. asks if this is the environmental material of the future and explores its mainstreaming potential.
In the future, the high cost and scarcity of fossil energy may force a shift towards retaining and modernising old buildings, thereby avoiding the use of huge amounts of energy to manufacture building materials. John Hearne visited the Belvedere Orphanage, a group of 19th century dwellings whose low energy refurbishment may offer a template for development in the future, by using wood pellet district heating and a host of energy saving measures whilst nonetheless paying great attention to preserving the buildings’ heritage value.
High energy prices and growing public eco awareness is leading to a situation where people are giving existing homes energy upgrades on an unprecedented scale. Two recently renovated houses in Dublin are at the extremes of how even the most difficult existing dwellings can be made greener, as Jason Walsh reveals.
Designing a low-energy public building with passive ventilation and lighting in mind is one thing – making it fit seamlessly into a rural wetland environment is quite another. Lenny Antonelli visited the award-winning Ballybay Wetlands Centre in County Monaghan - a closed-panel timber frame structure designed to sit softly on the surrounding landscape.
Walter P. Toolan and Sons, a firm of solicitors in Ballinamore, County Leitrim has redeveloped its office with the intention of creating a healthy, environmentally sound building. Jason Walsh visited the office to find out more.
Germany has a reputation for high quality craftsmanship, an attention to detail and a positive attitude to sustainable and healthy housing. Jason Walsh visited a new German-built house in County Dublin to see if the expertise can be exported.
A sustainable building must address more than energy, carbon or materials, argues Irish born architect Stephen Roe of up-and-coming London architects Roewu – it must respond to its environment. Not only does Roe’s design for the All Weather House achieve that, it boasts green materials, renewable heating and generous insulation too.
The cement industry is well known as being amongst the worst culprits for emitting CO2, a seemingly unavoidable side effect of its production. However, as Peter Seymour, Business Development Manager with Ecocem Ireland Ltd explains, there is a strong, eco-friendly competitive alternative to Portland cement that is being specified in a variety of high profile construction projects in Ireland.
