The document presents concept designs for renovating the Cleveland Park Library. It includes plans and diagrams of the existing building layout. The proposed design aims to achieve net zero energy use through energy efficient features. Precedent images show design elements to incorporate such as civic scale massing, a glassy ground floor, gardens, and natural lighting. Renderings depict the proposed design which emphasizes a storefront on Connecticut Avenue, a tower at the corner, and porch elements on the residential side. The goal is to celebrate books and spaces for social interaction while respecting the surrounding context.

Net Zero Energy

11. • Make as much or more energy as the building uses over the
course of one year
• Solar and Geothermal as primary energy generators
• Factors are: Building envelope, Glass, Lighting, Shading,
IT load, Hours of use
• Energy Use Intensity (EUI ) as metric
Energy Strategy – Net Zero Objective

Looking at EUIs

14. • Well Insulated, Non-drafty Building Envelope
• Smart Use of Glass (good daylight, limit heat gain)
• Energy Efficient Lighting (LED)
• Daylight Dimming & Motion Sensing Controls
• Every Efficient HVAC (geothermal,Water based Systems)
• Buy-in from Occupants ( Un-plug at night, open and close windows and
shades)
• Get Creative! (sewer system connected heat pumps? Using water for thermal
mass? Double walled sun room spaces?)
How would we get there?
