Slide 3:Green is not just about buying new materials
Preservation conserves our built resources
Energy conservation is compatible with preservation
Here is our “Top Ten” list of reasons…
Slide 5:Note construction of joint, peg is being replaced
Slide 6:New lumber Old lumber
Slide 8:Chances are your windows are more than 50 years old already, many are well over 100 years old
Maintain old windows once for decades more service
Replace windows and enter the 15-20 year replacement cycle
Slide 10:Wood can be repaired, how do you repair vinyl?
Slide 11:Original windows were part of the design and scaled to fit the proportions of the building.
Replacement windows change the character of the window and alter the physical fabric of antique and historic buildings.
Slide 13:Surface of window is very cold (dark blue), where panes are cracked on decorative window cold air is coming through
Slide 14:Surface of window is very cold (dark blue), where panes are cracked on decorative window cold air is coming through
Slide 15:These thermal pane windows also show significant surface cold area, but a remarkable amount of cold leaking in around the edges. Same house, 10 year old insulated glass replacement windows
Slide 16:Antique 6/6 windows Lots of glazing missing Install spring bronze weather stripping Re-glaze exterior Re-install sash and new sash lock
Slide 17:Before maintenance, overall cold surface, leakage around edges Significantly warmer surface area, still some leakage at corners to be addressed, gaps in trim to be caulked.
Slide 18:This bay of new windows show the cold air entering along the floorboards The leaky ceiling can lights were of great concern Even an uncovered outlet was a significant leakage point The auditor felt this ceiling vent to the attic was the number one infiltration problem for this home.
Slide 19:Where Does the Green Grow? 10. Because the greenest building
- is the one that is already built Product Life Cycle
Raw Materials
Manufacturing
Maintenance
Disposal at End of Life
Slide 20:Wood
Vinyl
Aluminum Almost 100% Usable and Recyclable
Offensive Chemicals and Minimal Recyclability
High Energy to Mfg., But Easily Recyclable
Slide 21:Wood
Vinyl
Aluminum
Transportation: Lowest Embodied Energy
>>> Wood
>>>>> Wood
Assume Roughly Comparable
Slide 22:Wood
Vinyl
Aluminum
Assume: High
Low
Location/Climate Dependant
Comparable Climate and Conditions
Slide 23:Wood
Vinyl
Aluminum 100 to 200 Years, Biodegradable, Harmful Coatings, Recyclable
10 to 30 Years, Not Biodegradable, Minimally Recyclable
Highly Recyclable, Harmful Coatings, Not Biodegradable
Slide 24:Public Policies
Growth in Green Building
Shifting Consumer Priorities
Slide 25:The long lifetime, low environmental impact of wooden windows, both installed, and new sales, may assume a dominant market position.
Restoration and weatherization of installed wooden window base may appear to the consumer more attractive than vinyl or aluminum, both residential and commercial.
