Moffett RAB: Navy EPA Intrusion Update

For closed environment, the characteristic is that the confined space is small and it doesn't flow with the outside world, it will produce nausea, dizziness, weakness and other symptoms if one stayed in that environment for long time. For this, developing a monitoring system of air quality in closed environment has theoretical significance and great value. In this paper, a modular design method is used to design a closed air quality monitoring system, The air quality monitoring system is composed of a main board and detection modules. When the measured closed environment is changed, it is only necessary to add or reduce the corresponding detection module, which increases the flexibility of the system and the convenience of later maintenance, and evaluation algorithm based on fuzzy mathematics is established. The measurement and air quality evaluation experiments are carried out using the developed monitoring system, The results show that the air quality evaluation algorithm can effectively evaluate the environmental air quality, and the measurement accuracy of the environmental parameters can meet the relevant standards.

Improvements in building efficiency can significantly reduce carbon emissions and are an intrinsic component in greenhouse gas reduction targets. The Passive House concept provides a framework for high-performance building that is growing in popularity in Canada, and particularly in the Pacific Northwest. The Passive House standard requires its buildings to achieve specific performance values for heating energy use intensity, total energy use intensity, spatial temperature variation, heat recovery ventilation performance and air leakage rate. The promised co-benefits of Passive Houses include superior thermal comfort and indoor air quality. Passive House design is not prescriptive and can incorporate many different design aspects. The wall assembly is no exception. This paper evaluates the hygrothermal performance of a deep-stud wall assembly of a Passive House in Victoria, BC, with regards to moisture durability. The concern with deep or doublestud wall assemblies is the combined effects of reduced drying with wall configurations that place moisture sensitive materials in riskier locations. Consequently, enclosure monitoring was undertaken in an occupied six-plex over the period of one year. The enclosure monitoring sensor packages were installed in strategic locations in the wall assembly to monitor the conditions of the assembly. The assemblies were evaluated based on the results of an empirical mold risk index. The wall assembly appears to perform acceptably, with minor concerns of mold growth on the North wall. Air leakage is a significant concern for cavity insulated walls, but the airtightness requirements of Passive house minimize this risk.

This document discusses solutions to overcome overheating in apartments. It begins by highlighting that overheating and noise are significant problems according to surveys. It then discusses regulations and standards around overheating before examining passive and mechanical design solutions. Passive approaches include orientation, shading, high thermal mass, natural ventilation. Mechanical options include MVHR systems, with or without additional fans, heat pumps or cooling coils. The document compares performance and costs of different ventilation solutions.

The document discusses the American Gas Association's (AGA) role in interacting with codes, standards, and regulatory organizations to represent the natural gas industry. The AGA serves on numerous standards writing committees, works to influence federal and state agencies, and aims to shape regulations impacting natural gas appliances and services. Key points covered include potential impacts of efficiency standard changes on gas water heaters and furnaces, and an analysis of new emissions limits for water heaters in Texas.
