Learning Objectives At the end of this program, participants will be able to: 1. Measure the constraints and benefits of CLT in construction and use this knowledge to ascertain whether CLT is a viable construction option for future projects 2. Explore the difference between the approach to school design in the UK and compare with school design in the US CLT Academy Building in UK Raleigh and Atlanta Wood Solutions Fairs 3. Examine the methodology and thought process behind the design of the two example Academy's and formulate a view of the rationale behind the design 4. Identify the balance between exposing the CLT for aesthetic purposes and lining the CLT for acoustics purposes using the completed project to weigh up the benefits of each.)

2 City Academy, Norwich, UK Building Form Options and Concept Exploration of building forms and architectural strategies Building Form Development Inspirations and Precedents Timeless Pavilion Design Classical & Civic Design Embracing communities

3 Inspirations and Precedents Site Conditions to determine location on site Why CLT for City Academy Structural Model of City Academy + CO2 saving steel/precast vs timber 1,100t CO2 (embodied) equivalent to 4.4 million car miles + (Sequestered) 2900t CO2 stored in timber equivalent to 11.6 million car miles + CO2 saving (sequestered) school is carbon neutral for over 10 years? Or equivalent to 57% renewable energy over 20 years + Exposing the timber structure where possible is an aesthetic decision + Timber maintains structural integrity longer than steel in event of fire + Fast erection time + Air tight building. Requires minimal heating CLT as structural façade throughout

10 Brief Building Location School for year olds 6 th Form for years olds 9,100m2 Building Area D&B Contract BREEAM Excellent Specialism of Environment and Engineering Won in Competitive Bid Environmentally low impact selection of materials The Academy should be accessible, warm, friendly, welcoming, secure and robust. It should be sustainable, non-institutional, naturally lit and colourful, with integrated indoor/outdoor areas that are easy to navigate and for a full range of learning and social use. Key Views and desire lines Key Views and desire lines
