Air Flow Control in Buildings

Oct 15 2007Introduction It has long been recognised that the control of air flow is a crucial and intrinsic part of heat and moisture control in modern building enclosures [Wilson 1963 Garden 1965] ] That this statement is true for all climates has been a more recently developed awareness [Lstiburek 1994] A large fraction of a modern well-insulated building's space conditioning energy load is due to

Carpenter ants

Branches touching a building allow easy access to ants Replace moisture-damaged wood Prevent moisture from wood or lumber that is stored in a garage or near the house by elevating it to allow air circulation Store firewood as far away from buildings as possible Remove tree

Isolation of Environmental Bacteria from Surface and

The aim of this study was to isolate and identify environmental bacteria from various raw water sources as well as the drinking water distributions system in Mafikeng South Africa and to determine their antibiotic resistance profiles Water samples from five different sites (raw and drinking water) were analysed for the presence of faecal indicator bacteria as well asi Aeromonas/i andi

Stakeholder Identification

The first step of a stakeholder analysis is to identify the key stakeholders — i e those who are affected by the outcome negatively or positively or those who can affect the outcomes of a proposed intervention (NETSSAF 2008) — from the large array of institutions and individuals that could potentially affect or be affected by the proposed intervention (RIETBERGEN-McCRACKEN et al 1998)

Air Conditioner Selection: If you are building a new home and can choose then choose an air conditioning system with a variable speed air handler and an operating selection mode for "enhanced moisture removal " This is a good option for multiple reasons: the units are SEER 14+ they are quiet and they do a better job removing moisture

A WATER SUPPLY AND SANITATION STUDY By Andrea C

the 38 water sources had water available year round and all s had access to a water source with year round availability The distance traveled to collect water ranged from 3 to 260 meters and the average distance traveled was 44 meters Although all s had reasonable access to a water supply not all s collected water

Sustainability measurement

Sustainability measurement is the quantitative basis for the informed management of sustainability The metrics used for the measurement of sustainability (involving the sustainability of environmental social and economic domains both individually and in various combinations) are still evolving: they include indicators benchmarks audits indexes and accounting as well as assessment

Damp (structural)

Structural dampness is the presence of unwanted moisture in the structure of a building either the result of intrusion from outside or condensation from within the structure A high proportion of damp problems in buildings are caused by ambient climate dependent factors of condensation and rain penetration Capillary penetration of fluid from the ground up through concrete or masonry is known

2 WATER SOURCES AND WATER AVAILABILITY

2 1 1 Water sources The water needed to supply an irrigation scheme is taken from a water source The most common sources of water for irrigation include rivers reservoirs and lakes and groundwater Figure 2 shows a 's-eye view of different irrigation water sources Figure 2 - Schemes irrigated from different water sources 2 1 2 Water

ELECTRICAL B POWER DISTRIBUTION BASIS OF DESIGN

This section applies to the design and installation of building power distribution systems Design Criteria This section contains the architectural structural and mechanical provisions for building electrical systems The electrical designer shall coordinate these requirements with the other disciplines to ensure these requirements are satisfied

Types of Moisture Meters: How Do Moisture Meters Work?

A moisture meter is an essential instrument used in many industries to detect moisture content in materials Home and building inspectors rely on moisture meters to identify potential problems and damage to structures from moisture buildup Woodworking industries such as furniture makers use wood moisture meters to insure a quality product

Water Distribution System Challenges And Solutions

Sep 09 2014Today a water supply system consists of infrastructure that collects treats stores and distributes water between water sources and consumers Limited new natural water sources especially in the southwest region of the USA and rapidly increasing population has led to the need for innovative methods to manage a water supply system

7 simple ways to improve energy efficiency

Many buildings in Canada are now being built or retrofitted to the green standard known as LEED (Leadership in Energy and Environmental Design) It aims to improve the sustainability of buildings in such areas as site planning water efficiency energy use

Soil Classification and Identification (With Diagram)

At this water content the soil has very small value of shear strength (ii) Plastic Limit: The water content which marks the boundary of the plastic state and semi-solid state of the soil is called its plastic limit W p Plastic limit of the soil is the minimum water content at which soil can be rolled into a thread of 3 mm without cracking

Water Quality Protection Nonpoint source water pollution occurs as a result of runoff and shallow groundwater flow from urban and rural areas Nonpoint source pollution is estimated to be responsible for 99% of sediments 88% of nitrates 84% of phosphates and 73% of the biological oxygen demand in our lakes and streams (Clark et al 1985)

DETERMINATION OF MOISTURE AND TOTAL SOLIDS

The water in the sample evaporates and moves up into the condenser where it is cooled and converted back into liquid water which then trickles into the graduated tube When no more water is collected in the graduated tube distillation is stopped and the volume of water is read from the tube 3 5 3 Practical

Soil Moisture

According to NASA's Earth Science Office soil moisture means different things in different disciplines A farmer's concept of soil moisture is different from that of a water resource manager or a weather forecaster Generally however soil moisture is the water that is held in the spaces between soil particles Surface soil moisture is the water that is in the upper 10 cm of
