At the same time it is also recommends that people think about fixing their homes for radon levels between 2 pCi/L and 4 pCi/L. [98] In the United Kingdom the ideal is presence of radon indoors is 100 Bq/m-3. Action needs to be taken in homes with 200 Bq/m −3 or more. [99]
[5] [39] Costs for global implementation have been estimated at $1.25 to $2.5 trillion or about 3% of global GDP, with expected economies of scale. [38] Low-cost scalable materials have been developed for widescale implementation, although some challenges toward commercialization remain. [40] [41]
The goals of NRAP are to continue efforts set forth by FRAP to eliminate radon induced cancer that can be prevented by expanding radon testing, mitigating high levels of radon exposure, and developing radon resistant construction. [87] NRAP also aims to reduce radon risk in 5 million homes, and save 3,200 lives by 2020. [87]
V08 Physical Activity Spaces and Equipment, providing indoor fitness space at no cost receives 2 points either the space includes two types of exercises or equipment that allow use by at least 5% of occupants at any time or has minimum size of 25 sq. m plus 0.1 sq. m per occupant until 930 sq. m, but WELL also allows if the project gives free ...
In the United States, passive house design was first implemented by Katrin Klingenberg in 2003 when she built a passive home prototype named "The Smith House" in Urbana, Illinois. [26] Later, she and builder Mike Kernagis co-founded the Ecological Construction Laboratory in 2004 to further explore the feasibility of the affordable passive ...
The construction industry is the number one user of phosphogypsum in 2020, with 10.5 Mt used as concrete set retarder and 3.5 Mt used in drywall. [13] It is also used as a chemical feedstock for producing sulfates , and as a soil conditioner similar to regular gypsum. [ 14 ]
Radon is thus assumed to be the second leading cause of lung cancer after smoking, and accounts for 15,000 to 22,000 cancer deaths per year in the US alone. [9] [better source needed] However, the discussion about the opposite experimental results is still going on. [10] About 100,000 Bq/m 3 of radon was found in Stanley Watras's basement in 1984.
This octagonal spire was for ventilation purposes, in the more complex system imposed by Reid on Barry, in which it was to draw air out of the Palace. The design was for the aesthetic disguise of its function. [40] [41] A more sophisticated system involving the use of mechanical equipment to circulate the air was developed in the mid-19th century.
