THE REFERENCE LIBRARY
Understand your home, one system at a time.
Practical explanations with worked examples, checklists and sources.
Insulation
Browse this topic03A warmer house starts with the right diagnosis.
Find heat losses, compare insulation and avoid trapping moisture inside a wall.
Why does water collect on cold windows and walls?
Use temperature, humidity and dew point to distinguish condensation from other moisture problems.
Ventilate an airtight home without losing control of heat
Separate required fresh air, local exhaust, infiltration and heat recovery.
Frost & ground
Browse this topic04How deep should pipes and foundations go?
Separate frost protection, pipe cover and structural foundation design before digging.
Prepare the house before the first hard freeze.
Walk through exposed water systems, heating dependencies and outage actions while there is time to fix them.
Protect exposed pipes before relying on heat trace
Reduce exposure, insulate correctly, choose controls and plan for a power failure.
Turn frost requirements into foundation levels on site
Separate the local frost criterion, structural bearing level, final grade and excavation level before digging.
Wells & water
Browse this topic04Will a well supply the water your home needs?
Read well logs, understand drawdown and turn flow measurements into pump and storage questions.
How much rainwater can your roof collect?
Estimate catchment yield, understand storage limits and keep rainwater separate from drinking water.
Choose a water pipe size without guessing
Connect fixture demand, internal diameter, velocity, pressure loss and pump performance.
Understand pressure, head and flow in a private water system
Measure static and dynamic pressure, include elevation and read the pump at its operating point.
Water treatment
Browse this topic03Which water filters do you actually need?
Choose stages from measured contaminants, treatment goals and required flow.
Read a private-well water test before choosing treatment
Check the sample, units, detection limits and health context before comparing equipment.
Maintain a home water-treatment train as one system
Track flow, pressure, capacity, sanitation and verification across every treatment stage.
Wastewater
Browse this topic02Plan a septic system around the site.
Understand the tank, soil treatment area, hydraulic load and maintenance obligations.
Plan a gravity drain from elevations, not appearances
Turn a required grade into invert levels while protecting cover, access and the downstream system.
Independent energy
Browse this topic05Build a power plan that survives a cloudy week.
Separate energy, peak power and autonomy before sizing solar, batteries and backup.
Choose backup power around the loads that must run.
Understand running power, motor starts, safe placement and the connection to the house.
Plan domestic hot water as an energy system
Estimate heating energy, then account for peak demand, recovery, storage and safety.
Plan how an off-grid battery gets recharged
Connect usable deficit, charger power, source limits, losses and recovery time.
Plan off-grid energy through several low-sun days
Build a period energy balance, preserve battery reserve and define when backup generation starts.
Construction
Browse this topic03Estimate a concrete order without hiding the assumptions
Separate drawing dimensions, geometric volume, allowance and supplier constraints.
Plan trench quantities without treating excavation as a safe shape
Estimate spoil while keeping utilities, collapse protection, water and access as separate decisions.
Size the roof-drainage path from rainfall to safe discharge
Connect roof area and design intensity to gutters, outlets, downpipes and foundation drainage.
