Airtightness with Fresh Air: Comfort Without Compromise
Making 0.6 ACH50 Practical on Real Jobsites
From taped sheathing to smart membranes, every seam counts. Sequence matters: air-seal as you go, test early, and fix before finishes hide errors. One team shaved leakage in half by adding a mid-construction blower-door test. Post your favorite tapes, gaskets, and details that never let you down.
Designing HRV/ERV Systems for Quiet, Clean Air
Right-sized HRV/ERV units with short, smooth duct runs whisper instead of roar. Balance supply and exhaust, consider defrost strategies, and choose cores based on climate. Occupants notice fewer headaches and less dust. What boost switch locations and filtration setups have given your clients the biggest smiles?
From Drafty to Delightful: A Field Story
A 1960s bungalow went from howling winter drafts to a steady, gentle hush after air-sealing and ERV commissioning. The owners reported warmer floors, fewer colds, and lower bills. They even hosted neighbors to feel the difference. Share your before-and-after airtightness numbers and what surprised you most.
Windows and Solar Strategy: Light Without the Losses
Orienting for Daylight and Seasonal Gains
Size south glazing to welcome winter sun while avoiding summer spikes, and keep west glass modest to tame late heat. Even small layout shifts can cut cooling loads noticeably. Have you modeled SHGC trade-offs or used external shading to tune performance? Tell us what worked in your latitude.
Mechanical Systems That Match the Load, Not the Guess
Heat Pumps Chosen by Calculations, Not Hope
Do a proper Manual J or EN 12831, include envelope improvements, and then select variable-speed equipment. Oversized units short-cycle and miss dehumidification. A retrofit in a coastal climate cut bills by a third after downsizing. What load calculation tools have earned your trust?
Efficient Hot Water with Less Waste
Heat pump water heaters, compact plumbing layouts, and drain-water heat recovery slash energy and wait times. Kitchens and baths feel snappier, and utility rooms run cooler. Have you tried recirculation with smart timers to tame losses? Share the setup that balanced comfort and savings.
Controls, Zoning, and Ventilation Harmony
Link thermostats, ERV boosts, and occupancy sensors so systems cooperate instead of fight. Gentle, steady operation beats aggressive bang-bang cycling. Owners notice quieter rooms and steadier humidity. Tell us which control sequences delivered the biggest real-world comfort gains.
Lower-Carbon Concrete and Thoughtful Mix Designs
Supplementary cementitious materials and optimized mixes cut cement content while meeting structural needs. Even modest substitutions add up across slabs and footings. On one school project, careful batching met schedule and slashed emissions. What percentage replacement has worked reliably for you?
Mass Timber and Bio-Based Insulation
Cross-laminated timber and wood-fiber insulation offer warmth, speed, and carbon storage. Pair them with airtight membranes and thoughtful vapor control for durable assemblies. Crews report fast installs and happier interiors. Have you modeled moisture behavior in these assemblies? Share your lessons.
Reclaimed Materials and Circular Construction
Deconstruction, reclaimed doors, and recycled steel reduce impacts and often add character. Plan early to align schedules and sourcing. Clients love stories behind materials that saved energy twice. Tell us your best find and how it affected the project’s performance.
A Commissioning Checklist That Catches Gremlins
Verify airflow, balance ventilation, confirm setpoints, and test dehumidification modes. Label everything and hand owners a simple guide. Many callback headaches vanish. Share your favorite line items that always reveal hidden issues before occupancy.
Monitoring for Feedback, Not Surveillance
Smart meters, indoor air quality sensors, and energy dashboards help occupants tune behavior gently. Focus on insights, not alarms. A monthly check-in often prevents seasonal drift. What metrics do you watch to keep performance honest?
