1 CHASE COLLEGIATE SCHOOL Upper School Expansion Campaign Donor Reception April 24, 2008

2 Rendering of Upper School Expansion

3 Upper School Architectural Design  Green design considerations: Environmental impact of production and use of materials Capturing passive and active solar energy Durability of materials Siting the addition to maximize the angle of the sun throughout the year

4 Groundbreaking April 3, 2007

5 Design Feature  The raised roof and high-reaching glass along the Second Floor Clerestory on the north side allows natural sunlight to illuminate the hallway, reducing the need to burn electricity.

6 Groundbreaking April 3, 2007

7 Design Feature  The rectangular wing is oriented to absorb maximum sunlight and solar heat through its large windows during the cooler months. The southerly roof overhang blocks the direct sun during the warmer months when the sun is more overhead but allows the warming sun into the room during the winter, when the angle of the sun is lower in the sky.

11 Design Feature  The flat roof areas on the South Wing are covered by a durable, white membrane. The white roof reflects the sun’s heat, keeping the roof cooler during hot months, reducing overall energy costs.  Roof solar reflectivity can help reduce “urban heat- island effect”, a metropolitan phenomenon that makes cities hotter and more uncomfortable than the countryside.

13 Small Changes, Huge Impact  If every household in the U.S. replaced just one 500 sheet roll of toilet paper with one made completely from recycled paper, 423,900 trees would be saved annually.

15 Small Changes, Huge Impact  If every American home replaced one conventional light bulb with a compact fluorescent bulb, enough energy would be saved to light more than 3 million homes for a year, save more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.

18 Lighting  The Upper School’s lighting choices reduce electricity use and preserve the Earth’s limited resources.

20 Mechanicals  The building’s heating and ventilation system transfers the heat from outgoing exhaust air and uses it to pre-heat the fresh air coming into the building, saving substantial energy by not having to heat up fresh air from the outside temperature throughout the colder months.

21 Excitement is building!

22 Mechanicals  Ventilating classrooms requires a great deal of energy. Our building automation system can be programmed to reflect the School’s schedule, enabling ventilation to only be supplied to classrooms when class is in session.  A manual override equipped with a timer accommodates unscheduled gatherings.

23 Excitement is building!

24 High Efficiency Products  The high-efficiency insulation within the walls and ceilings keep interior rooms eight degrees cooler in the summer and five degrees warmer in the winter than what standard insulation provides, saving energy.  The plumbing fixtures save energy and expense by heating hot water “on demand” - rather than all night, all weekend and throughout the summer and school vacations.

25 Excitement is building!

26 Building Materials  Adhesives used in the new wing are water-based and have a low content of volatile organic compounds (VOC), preserving the health of the indoor environment. VOCs released in the outside atmosphere damage soil and groundwater and exacerbate air pollution.  The wallboard material in this wing uses recycled gypsum and kraft paper.  The ceiling tiles are made from 28% recycled materials (1% post-consumer and 27% post-industrial ), avoiding the need to use scarce petroleum products to create new tiles from 100% raw materials.

30 Small Changes, Huge Impact  If just one in 10 homes used ENERGY STAR qualified appliances, the change would be like planting 1.7 million new acres of trees.

31 Excitement is building!

32 Lighting  The overhead lights contain photocells which monitor daylight, dimming automatically when illumination from the sun is sufficient.  Motion-sensitive lights provide illumination only when there is occupancy.  Compact fluorescent lights use one quarter of the electricity that conventional light bulbs use and last ten times longer.

33 Excitement is building!

34 Bathrooms  Low-flush toilets will use merely1.6 gallons of water, compared to 3.5 gallons used by standard ones  Slow-rolling toilet paper dispensers save hundreds of trees per year versus conventional units.

35 Excitement is building!

36 The Bistro

37 Appliances  The Upper School Bistro will be equipped with Energy Star appliances.  ENERGY STAR qualified appliances incorporate advanced technologies that use 10–50% less energy and water than standard models reducing greenhouse gas emissions without sacrificing features, style or comfort.

38 Student Lounge

39 Excitement is building!

40 Windows  All window glass is gas-filled and has a low emmitance (low-E) coating - reducing the overall transfer of heat between the inside and outside of the building.  The low-E glazing also ensures visual comfort throughout all the day-lit spaces.

41 Second Floor Classroom

42 Lighting  To maintain classroom lighting levels, a combination of day-lighting and electric lighting is in place.

44 Using Green Products  The use of “green” cleaning agents on the floors and walls and counters and within the bathrooms in the Upper School eliminates dangerous chemicals that may cause illness and allergies in those who are exposed to them. Such steps reduce emissions and provides a cleaner, less toxic environment. This improved setting is particularly important in schools and healthcare facilities, where many people are sharing confined spaces.

45 Using Green Products  Chase’s Green Team has introduced “Green Purchasing Guidelines” that direct Chase to give preference to environmentally superior products, where quality, function, and cost are close, equal or superior.

46 Excitement is building!

47 Interior Products  The carpet in this building has a high percentage of recycled content and was specifically purchased from manufacturers with reclamation and recycling programs.  The linoleum flooring used protects the Earth’s non- renewable resources because it is made from biodegradable, 100% natural materials: linseed oil, rosins, cork and wood flour.  The ceramic tile in this wing has more than 60% recycled content. The manufacturing process uses post- industrial feldspar waste as its primary raw material.  The fabric on most of the upholstery is 100% post- consumer recycled polyester from soda bottles.

48 Excitement is building!

49 Roofing  Durability often gets overlooked as an aspect of sustainable building, but it is one of the most important aspects of a materials characteristics: the volume of material in our landfills is a result of product fatigue

50 Excitement is building!

51 Roofing  The metal roof on the South Wing is designed to last three to four times longer than conventional roof shingles and will last even longer protected by the 288 solar panels. The metal roof has over 25% recycled content and is 100% recyclable at the end of its life cycle.

52 Excitement is building!

53 Exterior  Xeriscape gardening emphasizes water-saving techniques, such as the use of mulches and drought- tolerant shrubs and flowers.  The landscaping around the building will consist primarily of low-maintenance native plants, requiring less water and therefore less electricity to keep them healthy.  A rainwater harvesting system captures rainwater from over 50% of the building’s roof and stores it in the pond for irrigation of the athletic fields.

54 Excitement is building!

55 Solar Array  Solar energy causes electrons within the panels to be ‘freed’ from certain materials. The electrons then travel through an electrical circuit as DC (Direct Current) power. An inverter is needed to convert the DC power to AC (Alternating Current) – the power that lights our lights and provides electricity at outlets.

56 Solar Panels

57 Solar Array  The 288 solar panels on the Upper School roof are each designed to produce 225 watts of electricity for a combined maximum output of 64.8 kilowatts.  In this “net metered” system, when more power is produced than the School requires, the excess power is returned to the electrical grid for financial credit to Chase.

58 Solar Array  Over the next 25 years, the system will reduce the emission of 1,783,944 pounds of carbon dioxide, 7,557 pounds of sulfur dioxide, and 2,983 pounds of nitrogen oxides into the Earth’s atmosphere.  Installing the solar array is the equivalent of planting 8,325 trees or avoiding 1,951,371 miles of driving.

59 Solar Array  Annually, the entire array will produce 76,753 kilowatt hours, supplying 40% of the building’s electrical needs.
