23. Paul Dunne 21st May 2010 Low Carbon Building Solutions Thank You
Editor's Notes
There are a variety of definitions of zero carbon, from a completely autonomous building “off-grid” with it’s own renewable generation, to net zero carbon, where the grid acts as an effective store for on-site generation of variable output, to green tarrifs and carbon off-setting. Net Zero Carbon is the generally accepted definition of Zero Carbon in the building industry, although the requirements for proximity of the generating capacity to the site vary between definitions and standards
Typical Carbon Footprint of a new build office
Gradual Behaviour Change with information and education Example: energy-efficient appliances Recent research from the Energy Saving Trust indicates just under 60% of people look for energy efficient models when purchasing an appliance. In 2005, for example, more than 90% of washing machines sold in the UK were the most energy efficient “A” rating, compared with just over 40% in 2001: a doubling within four years. If people are given the right information and incentives, they will change their behaviour. Source: “ Action Today to Protect Tomorrow: Mayor’s Climate Change Action Plan”. Greater London Authority.

Sustainable design elements like: • Twin & triple skin facades to corporate office buildings • Heat recovery ventilation system to apartments • Low energy light fittings are all well understood More recent solutions now coming to the fore include district heating systems for mixed use developments. The scheme also employs a 2MW biomass wood pellet boiler which provides the base heat load to over 1,000,000ft of building space in the development. I will come back to this later on.

Variation in cost of low and renewable energy technologies. The most cost-effective technologies tend to be those applicable at a larger scale
This approach can offset the full carbon footprint of a development through the use of renewable fuels
The cash flow implications relating to sustainability interventions will need to identified. Need to assess the ability of the developer/landlord to capture the value increase. This assessment will need to be tailored to local market conditions. This approach applies to all building types.
