BUILDING SCIENCE
Values
1) HEALTH AND SAFETY
1) Goals:
GOOD INDOOR AIR QUALITY
Strategy: Keep building dry
Actions: Follow moisture control strategies to create a well-detailed enclosure that avoids leaks, condensation, and groundwater intrusion.
Strategy: provide good ventilation
Actions: Install a well-sized and appropriately designed ventilation system for the home, and ensure it runs correctly
Strategy: Reduce Pollutants
Actions: Avoid products with off-gassing chemicals such as the solvents and the glues common in paints, floor ceilings, and furnishings
Strategy: Combustion Safety
Avoid the use of combustion appliances and/or use sealed combustion appliances when neceessary
1) Goals:
SAFE USE FOR ALL
Strategy: Universal Design (UD)
Actions: Follow established UD guidelines to ensure access to those needing assistance moving about in the home.
2) COMFORT
2) Goals:
Strategy: Control heat transfer
Actions: Follow thermal control strategies for a well-detailed, airtight and well-insulated enclosure, and include thermal mass inside the building
Strategy: Provide appropriate heating and cooling
Actions: Install a well-sized and appropriately designed heating/AC system for the home, and ensure it runs correctly and is serviceable.
Strategy: Keep surface temperatures warm
Actions: Insulate slabs, walls, and ceilings. Install thermally efficient windows
STABLE INDOOR TEMPERATURE
2) Goals
Strategy: install quality air barrier
Actions: Ensure air barrier detailing in design, and perform quality control in the field with a BLOWER-DOOR TEST
CONTROL AIR FLOW (NO DRAFTS WHEN COLD, CIRCULATION WHEN WARM)
Strategy: Good Ventilation
Actions: Install a well-sized and appropriately designed ventilation system for the home, and ensure it runs correctly.
2) Goals
CONTROLLED HUMIDITY LEVELS
Strategy: Same as other goals addressing comfort
Actions: Keep building dry, keep surfaces warm, install an appropriate ventilation system
3) DURABILITY
Goals
KEEP RAIN AND SNOW FROM GETTING IN
Strategy: Control bulk water entry
Actions: Follow moisture-control strategies of a well-detailed enclosure, avoiding leaks and groundwater intrusion
Strategy: Control surface water
Actions: Install storm water control (i.e., gutters)
Goals
KEEP CONDENSATION OUT OF THE ENCLOSURE
Strategy: Install quality Air Barrier
Actions: Ensure air barrier detailing in design, and perform quality control in the field with a BLOWER-DOOR TEST
Strategy: Appropriate ventilation system
Actions: Install a well-sized and appropriately designed ventilation system for the home, and ensure it runs correctly
4) RESOURCE EFFICIENCY
4) Goals
REDUCE NON_RENEWABLE ENERGY CONSUMPTION
Strategy: Control heat transfer
Actions: Follow thermal control strategies of a well-detailed air-tight and well insulated enclosure, avoiding thermal bridging
Strategy: provide appropriate heating and cooling
Actions: Install a well-sized and appropriately designed heating/AC system for the home, and ensure it runs correctly and is serviceable.
Strategy: Install renewable energy systems
Actions: Install solar electric or thermal panels; use biomass for solid-fuel heating
Goals
REDUCE WATER CONSUMPTION
Strategy: Use water-conserving appliances
Actions: Install low-flow faucets, shower heads, and toilets, and service regularly to eliminate leaks
Strategy: Integrate water-conserving systems
Actions: Design for rainwater catchment, grey water recycling, and composting toilet systems
Goals
REDUCE MATERIAL CONSUMPTION
Strategy: Re-use existing buildings and materials
Actions: Rehab buildings when possible; salvage what must be demolished; purchase quality used materials when possible
Strategy: Use low-impact materials
Actions: Use natural and regionally sourced abundant materials such as stone, wood, straw/hemp; select products with high recycled content (everything from steel to cellulose insulation)
5) SOCIO-ECOLOGICAL EQUITY
Goals
REDUCE ATMOSPHERE CARBON LOADING
Strategy: Same as Resource Efficiency
Actions: Same as for Resource Efficiency
Strategy: Reduce embodied carbon of building
Action: Choose low-carbon building materials and practices
Goals
REDUCE FOSSIL-FUEL CONSUMPTION
Strategy: Same as for Resource Efficiency
Actions: Same as for material Resource Efficiency
Goal
REDUCE TOXIC FOOTPRINT
Strategy: Same as for Resource Efficiency
Actions: Same as for material Resource Efficiency
Strategy: Use non-embodied toxic materials
Actions: Select materials that have a reduced industrial toxic footprint, avoiding petrochemicals, intensively mined and processed materials, and chemical solvents.
