Life in Community - Reflections from LILAC

This is my second post inspired by a visit to LILAC, an innovative co-housing project in Leeds built in 2013 using straw bale and timber construction. Lilac is an acronym that reflects the initiative's three core values: Low impact living (covered in my previous post),  affordable, community. I'll be writing more about the thorny issues of affordability and housing after attending a workshop hosted by Green Christian on the subject on 24th Jan.
When I try explaining Lilac to others, people usually can't imagine what I'm talking about. Eco-housing, certainly, but living in community?

Low Impact Living in Leeds: Three Stories

Yesterday I spent a great day visiting three friends in Leeds trying to live more sustainably in different ways. The day was sparked off by Isabelle, who has decided to take up the new year challenge I set myself in 2014 and measure her carbon footprint so I took along some resources I had found useful including George Marshall's book Carbon Detox.

This was also an opportunity to see her newly insulated house, having followed her blog (with photos!) describing her efforts and lessons learned.

Thinking Long Term: Learning from the Railways

This post is part of a series inspired by the book "Sustainable Infrastructure: Principles into Practice" (see the introduction to the series here). Having examined the issue of intergenerational stewardship and thinking long term about infrastructure (Principle 3) in my last post, how can we put this knowledge into practice in real civil engineering situations such as the railways?
Putting it into Practice 3.1: Plan for the Long Term
There is a need for future proofing, but all our predictions are scenarios: we need a clear statement for each line of what it would ideally look like in 20 years time, such that all projects work together to either facilitate the vision, or at the very least not get in the way. For example, the Harrogate Line was reduced from two tracks to one between Poppleton and Hammerton in the early 1970s, which means that it is now only possible to run one train per hour between York and Harrogate and any delays quickly escalate because the train in one direction can't pass a train which is running late in the other direction, so only 85% of trains run on time.

Thinking Long Term: Why "Doing it for the kids" is not good enough

Principle 3: Intergenerational Stewardship (or Thinking Long Term)
This post examines the concept of intergenerational stewardship, the 3rd principle of sustainable infrastructure (see the introduction to this series inspired by the book “Sustainable Infrastructure: Principles into Practice”).
We don't inherit the world from our ancestors, we borrow it from our children (Anon)
The concept of protecting the earth for our children has been one of the key ways that people have understood the environmental movement over the last 30 years. It has been posited that as a direct appeal to people's emotions, this is a strong motivation for people to act. Unfortunately, the evidence doesn't seem to support this view.

What is Infrastructure For? Social and Economic Sustainability Goals

Principle 2: Social and economic development

‘If you’re asking me to choose between conservation and development, I’m going to choose development every time.' Community worker in Democratic Republic of Congo

This is part of a series inspired by the book Sustainable Infrastructure. What is infrastructure for? And do we really have to make a choice between meeting people's needs and protecting the environment, as the quote above suggests? 


The purpose of most infrastructure is to improve social or economic outcomes (and let's face it, when one third of the world's people have no access to sanitation, there's no shortage of need) and that's why economic issues have traditionally been the biggest influence over project scoping and delivery.

For example, many projects are justified on the basis of a cost-benefit ratio, which may consider only benefits within the organisation (eg reduced maintenance and operation costs for a railway) or may additional calculate the wider economic benefits to users (eg the business case for HS2).

Putting it into practice 1: How do we live within our limits?

This post is part of a series inspired by the book "Sustainable Infrastructure: Principles into Practice" (see the introduction to the series here). Having examined the issue of planetary boundaries (Principle 1) in my last post, how can we put this knowledge into practice in real civil engineering situations? 

Two "operational" rules of thumb are proposed to ensure that all our buildings, transport etc protect rather than damage our planet's capacity to support life:

1.1: Set targets and measure against environmental limits
"If you can measure it, you can manage it"

Living within our limits: Exploring Planetary Boundaries

Sustainable Infrastructure - Principle 1. Environmental Sustainability - Living Within Our Planet's Limits 
This post explores the concept of planetary boundaries, the first principle of sustainable infrastructure (see the introduction to this series inspired by the book “Sustainable Infrastructure: Principles into Practice”).

Environmental Capacity:   
Sustainable development has often been described as the "triple bottom line" of financial (or economic), social and environmental impacts, with a lovely Venn diagram showing these three ideas working in harmony. However, this doesn't reflect the relative importance of the three elements: cost or economic benefits are usually considered to be the main driver for development, but there's little point having lots of money if the result is destroying the capacity of our one and only planet to support life!

Advent Reflections 7: Finding Our Purpose

 “For we know that nothing we do for the Lord is ever useless” 1 Cor 15:58 
At the beginning of a new year, many of us have hopes and dreams as well as fears for the future. So now seems like a good time to consider our purpose. A sense of purpose can be powerful enough to keep us motivated through difficult times, but it can be hard to find, especially when we are demoralised. The simple fact is, much of what we do feels pointless and too small to make a difference, a drop in the ocean.
Over the Christmas period, we have considered God’s awesome creation, made with love, the frustration of living in a world of sin and death (and the need tolament the tragedies of life) and his great plan for redemption through Emmanuel. This is where the final part of the Bible’s story comes into play for us: the consummation of all our hopes, the resurrection and redemptionof the whole world.
