3 Our Aim Use Demand Side Management to facilitate the embedding renewable energy to a Timber research centre Use Demand Side Management to facilitate the embedding renewable energy to a Timber research centre Apply design changes to match building energy demands with renewable supply. Apply design changes to match building energy demands with renewable supply. Show results through simulation and website. Show results through simulation and website.

9 Demand Side Management. Strategies utilised throughout the project. Strategies utilised throughout the project. Peak clipping Peak clipping Valley filling Valley filling Load shifting Load shifting Design changes made in order to implement these strategies. Design changes made in order to implement these strategies. How these changes have affected the demands of our design. How these changes have affected the demands of our design.

10 Design changes 1. Peak clipping To help lower the demand, we looked to significantly reduce the loads in the building Natural lighting. Natural lighting. Natural heating. Natural heating. Energy reduction in cafeteria. Energy reduction in cafeteria.

11 Design changes 2. Valley filling The goal is to build up off-peak loads in order to smooth out the load and improve the economic efficiency of the building. Heating slowly turned on in the morning before occupancy Heating slowly turned on in the morning before occupancy Heating during the weekends. Heating during the weekends.

12 Design changes 3. Load shifting The idea behind load shifting is to move the times of peak energy usage to times where there is a excess of electricity. Stagger times at which occupants enter the building. Stagger times at which occupants enter the building. Change designated break times throughout the day. Change designated break times throughout the day.

13 Effects of changes. Lower demand peaks in spaces, both in terms of heating and lighting. Lower demand peaks in spaces, both in terms of heating and lighting.
