Carbon Designer for Ireland

The Carbon Designer tool is a simple way to estimate the carbon impact of your project at an early stage of building design. The tool is free and quickly shows you the differences you can make to the overall carbon impact by selecting different material build ups of large elements such as walls, floors and roof.

Building Circularity

Developing Circular Economy concepts for buildings

Is circularity measurable? What are the key concepts to be considered when designing a building? In London circularity statements are required on larger developments at planning stage. How can these be prepared and what are the key things about designing to ensure zero waste and reuse of all components?

Circular Cities

The transition to a circular economy is not possible without coordinated, coherent action by multiple different stakeholders groups in the existing linear economy. Drawing on recent research from the EU Horizon 2020 CIRCuIT project, as well as expertise and experience from London and Finland, this webinar will explore essential practices and enablers for achieving a circular economy through decision-making by key actors within cities.

Reusing Materials -Buildings as Material Banks

What role can material exchange platforms play in ensuring that materials go into closed loops of reuse. How can we know that reused materials are fit for use and how do we track or source these materials? Materials Exchange provides a dating site for reused materials allowing them to be tracked through blockchain and made available across sectors providing information on ingredients and standards. How can the platform transform a mere building into a ‘Building As a Material Bank’? Can this approach work in Ireland?

Is Mass timber one route to circularity?

Waugh Thistlton is one of the leaders in mass timber construction in the UK. Mass timber construction offers an ideal way for circular low carbon construction. Not only can it speed up the construction process but it can minimise the need for finishes. Lightweight components allow easy demountability, easy connections and reuse options.

Introducing Life Cycle and Whole Life Carbon Thinking

Life Cycle Assessment of buildings and full carbon footprinting across the life cycle provides a powerful way of assessing the overall impact of a building and its components and is an essential tool in the transition to circularity. What are the relevant standards and how can professionals get started measuring and reducing the impact of their buildings.

Green Innovations Webinar Series

Green Innovations - Solutions from Timber

Wood is the quintessential low carbon building material. This webinar explores products and solutions available that use wood both structurally as a building component including wood fibre insulation, oriented strand board and cross laminated timber construction.

Presenters: David Murray Medite Smartply, Martin Twamley Steico, Lee Murphy G-Frame.

Green Innovations - Envelopes

Ensuring a high performance, continually insulated building envelope is key to achieving an energy efficient building. This webinar looks at the benefits of the SIMS solution, single leaf construction with external insulation and insulated foundation systems.

Presenter: Jason Martin – Mannok and Andrew Butler KORE

Green Innovations - Interiors

Choosing efficient and healthy interior products contributes to the overall sustainability of a project. In this webinar looks at low flow bathroom fittings and low impact paints and flooring.

Presenters: Pat Gatley Graphenstone Paints, Mark Bauer Forbo and Andrew Murphy, Bathquip

Green Innovations - Circularity

For building products to be truly sustainable, they need to be circular. This webinar showcases two exciting Irish examples of circularity, insulation made from newspapers and an aggregate made from construction demolition waste.

Presenters: John Egan Ecocel and Cian O’Hora IMS

Green Innovations - Renovation

The most sustainable building is an existing building, so renovating our building stock to be more energy efficient is key to achieving carbon savings. This webinar looks at mineral wool as a low-cost solution for mass renovation and heat pumps for water heating.


Presenters: Jason Horrex St Gobain and Cian Tobin Ideal Energy

Circularity in Practice: Case Studies Denmark & Cork

Circle House is the world’s first residential project designed and built after the principles of circular economy, which, among other things, means the building can be disassembled, and the project’s materials can be reused without loss of value.

Test site includes a pavilion, a ‘Coill Bheag’ (small native woodlands), seating and hoarding elements. The vision is one which sees a structure for public engagement constructed so that waste is prevented at each stage of its lifecycle, from design to the end of the TEST SITE Project.
