BS EN 14351-1 is the harmonized European Standard for windows & external doorsets. BS6375 provides guidance specifically on the appropriate performance levels required for the UK market for air permeability, watertightness and wind pressure.
Review the state fact sheets or use the window selection tool for new construction or existing homes from the Efficient Windows Collaborative to determine the desired performance ratings for your climate.
This calculator makes it easy for you to perform preliminary assessments of the Wind Load resistance of single glazed, annealed (not heat treated) window glass, with various edge support conditions, according to the ASTM E1300 standard.
The Window Energy Rating (WER) tells you how energy-efficient your windows are. The rating system is based on a scale of E to A++, with A++ windows being the most energy-efficient. The scheme is similar to those seen on household appliances, white goods and light bulbs.
The energy impact due to windows in a home depends on several design decisions—climate, window orientation, window area, shading conditions, and window (frame and glazing) type. Homeowners and designers need to know the answers to the following questions. What is the best window type to reduce energy use in a particular location?
1 sty 2005 · The figures and tables in the IRC amount to a road map for determining window requirements. The first step is to figure out your site's "basic wind speed," as found in the newly revised wind speed zone map from ASCE 7 (Figure 2). That gives you a starting value for wind pressures on your building.
