The document discusses opportunities and challenges for sustainable construction and design. It provides examples of sustainable building projects from around the world, including a Passivhaus school in Austria, the Hammarby Sjöstad development in Stockholm, and Paultons Park's new indoor play area in the UK. The case studies demonstrate how to design buildings to a higher sustainable standard through approaches like using local materials, passive design principles, and renewable energy systems.

2. Issues and challenges
I It is not only building skills and alternative solutions that are the challenge
I Avoiding Greenwash!: can only be understood with knowledge
I Human behavior, habits and methodologies need to change, this need
not cost money but takes commitment
I Embrace the principles of continuous improvement, do not accept convention
I Involution: combining innovation and evolution
I Proving low energy building performance: Building physics and dynamic modeling

3. There are opportunities in ALL sectors and not always new-build
Housing retro-fit challenge (Source BERR 2008)
I 80%+ of housing stock in the UK in 2050 already exists
I 500,000 houses to be transformed per year at approx £20,000 - 30,000 house for 40 years
I 200,000 construction jobs required to support the task
I The largest ever UK Engineering Project

4. Sustainable communities: how many opportunities do we want?
Community-scale wind turbine
Solar shading
Green roofing
Fuel-cell bus Waste-to-energy plant
Maintained ‘eco-system’
Combined heat and power plant
Refurbishment existing dwellings
Rainwater harvesting
District heating network
Smart metering
Sustainable drainage system Car re-charging
High-speed broadband
Ground-source heating Zero-carbon dwellings
Community recycling
There are examples around the world (even in the UK), get out and see them!

23. Visitor Centre
Taking full advantage of a 54 acre site, HPW created the concept and
developed the Visitor Centre to act as a hub for access to:
- 26 acre Country park
- 6 permanent mazes
- Countryside interpretation exhibition
- Retail offer
A purpose built 4,500 sq.ft. timber framed and clad building. In its
countryside setting the centre nestles beneath established trees
and oversails two lakes to form a gateway to the visitor attractions
and complementary retail operations.
