Goat farming is an important source of livelihood for many small-scale farmers in developing countries, particularly in regions such as sub-Saharan Africa and South Asia. The FAO estimates that more than 90% of the world’s goats are raised in developing countries, where they provide a critical source of food and income for rural communities.

Overall, the global goat farming industry continues to grow, driven by increasing demand for goat meat and milk products, as well as the potential for sustainable agriculture practices.

Advantages:

Low start-up costs: Goat farming requires relatively low start-up costs compared to other types of agriculture. Goats are small animals that do not require much space, and they can be raised in a variety of environments, from small backyard farms to large commercial operations.

High productivity: Goats are known for their high reproductive rate, which allows farmers to increase their herd size quickly. They are also efficient at converting food into milk and meat, making them a profitable investment for farmers.

Multiple uses: Goats can be raised for meat, milk, and fiber, making them a versatile livestock option. Additionally, their manure can be used as fertilizer, and they can be used for weed control on farms and other properties.

Sustainable farming: Goat farming can be a sustainable agricultural practice, as goats do not require large amounts of feed or water, and they can be raised on marginal lands that are unsuitable for other types of agriculture.

Disadvantages:

Predation: Goats are vulnerable to predation by coyotes, dogs, and other predators, which can be a significant problem for farmers, especially in rural areas.

Disease susceptibility: Goats are susceptible to a variety of diseases, some of which can be difficult to diagnose and treat. Additionally, some diseases can be transmitted to humans, making it important for farmers to take precautions when handling their animals.

Market volatility: The demand for goat products can be volatile, and prices can fluctuate significantly based on supply and demand. This can make it challenging for farmers to predict their income and manage their finances.

Labor intensive: Goat farming can be labor-intensive, especially during kidding and milking seasons. This can make it difficult for farmers to manage their workload, especially if they have a large herd.

Heat Tracing Installation

“Vue de toits (effet de neige)” 1878 Gustave Caillebotte

One of the core documents for heat tracing is entering a new 5-year revision cycle; a consensus standard that is especially relevant this time of year because of the personal danger and property damage that is possible in the winter months.  Education communities depend upon heat tracing for several reasons; just a few of them listed below:

  • Ice damming in roof gutters that can cause failure of roof and gutter structural support
  • Piping systems for sprinkler systems and emergency power generation equipment
  • Sidewalk, ramp and stairway protection

IEEE 515 Standard for the Testing, Design, Installation, and Maintenance of Electrical Resistance Trace Heating for Industrial Applications is one of several consensus documents for trace heating technology.   Its inspiration originates in the petrochemical industry but its principles apply to all education facilities exposed to cold temperature and snow.   From its prospectus:

This standard provides requirements for the testing, design,installation, and maintenance of electrical resistance trace heating in general industries as applied to pipelines, vessels, pre-traced and thermally insulated instrument tubing and piping, and mechanical equipment. The electrical resistance trace heating is in the form of series trace heaters, parallel trace heaters, and surface heating devices. The requirements also include test criteria to determine the suitability of these heating devices utilized in unclassified (ordinary) locations.

Its principles can, and should be applied with respect to other related documents:

National Electrical Code Article 427

NECA 202 Standard for Installing and Maintaining Industrial Heat Tracing Systems

IEC 62395 Electrical resistance trace heating systems for industrial and commercial applications

 ASHRAE 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings

Lowell House / Harvard University

We are happy to explain the use of this document in design guidelines and/or construction specifications during any of our daily colloquia.   We generally find more authoritative voices in collaborations with the IEEE Education & Healthcare Facilities Committee which meets 4 times per month in Europe and in the Americas.  We maintain this title on the standing agenda of our Snow & Ice colloquia.  See our CALENDER for the next online meeting.

Fireplace Safety


Many accommodations such as dormitories, fraternities and sororities have working fireplaces — wood burning and natural gas.  Community spaces such as student unions, libraries and recreation spaces also have fireplaces as a central feature.

The purpose of NFPA 211 is to reduce fire hazards by discovering and promulgating best practice for the safe removal of flue gases, the proper installation of solid fuel-burning appliances, and the correct construction and installation of chimneys, fireplaces, and venting systems.  The current 2019 Edition is linked below:

Free Access: NFPA 221 Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances

The 2024 has been released.  To guide our inquiry into safety and sustainability concepts for the 2027 Edition we like review the developmental transcripts of previous edition:

Public Input Report

Second Revisions Report

Public comment on the First Draft of the 2027 Edition will be received until June 3, 2025.  We encourage facility managers to recommend improvements to this standard by setting up a (Free) NFPA account the link below:

Online submission of public input and public comments

We maintain this standard on our periodic Prometheus and Housing colloquia.  Consult our CALENDAR for the next online meeting, open to everyone

Outdoor Deicing & Snow Melting

Electrical Safety

“Snow at Argenteuil” | Claude Monet (1875)

Today our focus turns to outdoor electric deicing and snow melting wiring systems identified as suitable for the environment and installed in accordance with the manufacturer’s instructions.  They work silently to keep snow load from caving in roofs and icicles falling from gutters onto pedestrian pathways.

While the voltage and ampere requirement of the product itself is a known characteristic, the characteristic 0f the wiring pathway — voltage, ampere, grounding, short circuit, disconnect and control — is relatively more complicated and worthy of our attention.   Articles 426-427 of the National Electrical Code is the relevant part of the NEC

Free Access 2023 National Electrical Code

Insight into the ideas running through technical committee deliberations is provided by a review of Panel 17 transcripts:

2023 NEC Panel 17 Public Input Report (633 pages)

2023 NEC Panel 17 Public Comment Report (190 pages)

We hold Articles 427 in the middle of our priority ranking for the 2023 NEC.   We find that the more difficult issues for this technology is the determination of which trade specifies these systems — architectural, electrical, or mechanical; covered in previous posts.   Instead, most of our time will be spent getting IEEE consensus products in step with it, specifically ANSI/IEEE 515 and IEEE 844/CSA 293.

Comments on the Second Draft of the 2026 NEC will be received until April 18th.

454c656374726f746563686e6f6c6f6779

We collaborate with the IEEE Education & Healthcare Facility Committee which meets online 4 times per month in European and American time zones.  Since a great deal of the technical basis for the NEC originates with the IEEE we will also collaborate with IEEE Standards Coordinating Committee 18 whose members are charged by the IEEE Standards Association to coordinate NFPA and IEEE consensus products.
