Study Notes

Understanding Wind Direction

Trees and shrubs should not obstruct wind entry through doors and openings in homes.
Wind effect ventilation relies on natural wind forces to circulate air within a building.
Stack effect ventilation (chimney effect) allows hot air to rise, creating upward air movement, while cold air remains at lower levels.

Government Regulations

Essential documentation includes transfer certificates of title, tax declarations, and contracts with contractors, signed by licensed professionals.
Building applications must be accompanied by structural designs, bills of materials, and a fire safety certificate checklist.
Location clearance includes zoning approval and compliance with local government unit regulations.

Land Preparation

Conduct soil testing and geotechnical engineering assessments before construction.
For structures three stories and higher, incorporate seismic analysis and load testing.

Occupancy Groups

Group A: Residential dwellings.
Group B: Hotels.
Group C: Commercial establishments (e.g., schools, churches).
Group D: Hospitals.
Group E: Various commercial types, including terminals and malls.
Group F: Industrial facilities, such as mills and breweries.
Group G: Factories and warehouses.

Roofing Materials

Membrane roofing is suitable for flat roofs; options include EPDM, PVC, and polymer-modified bitumens.
Asphalt composite shingles offer good durability with a warranty of 20-30 years and are adaptable to roof movements.
Standing seam metal roofing is fireproof, long-lasting, and requires specialized installation skills.
Metal shingles mimic traditional materials while offering durability and aesthetic appeal.
Wood shingles and shakes provide an attractive option but are less durable and unsuitable for damp climates or high-fire-risk areas.

Key Features of Roofing Materials

EPDM (rubber roofing) limits seams to reduce water infiltration and is highly effective for flat roofs.
Asphalt shingles are flexible and easy to repair, making them popular for a range of roofing applications.
Metal roofs are recyclable, highly durable, and ideal for heavy snowfall regions.
Wood shakes, thicker and rougher than shingles, offer natural beauty but have limitations in longevity and moisture resistance.
