Top 10 Questions for Home Performance Consultant Interview

1. Can you outline the key steps involved in conducting a home energy audit?

• Initial Assessment: Conduct a visual inspection of the home’s exterior and interior, review utility bills, and gather information from the homeowner.
• Data Collection: Use specialized equipment, such as a blower door and infrared camera, to collect data on air leakage, insulation levels, and thermal performance.
• Analysis: Analyze the collected data to identify energy inefficiencies, prioritize improvement measures, and estimate potential energy savings.
• Report Generation: Create a comprehensive report that summarizes the findings, provides recommendations, and outlines the estimated costs and benefits of recommended improvements.

2. How do you evaluate the efficiency of different heating and cooling systems?

• Seasonal Energy Efficiency Ratio (SEER):

  Measure the efficiency of air conditioners and heat pumps, indicating the cooling capacity relative to energy consumption.

• Heating Seasonal Performance Factor (HSPF):

  Determine the efficiency of heat pumps in heating mode, representing the heating capacity relative to energy usage.

• Annual Fuel Utilization Efficiency (AFUE):

  Assess the efficiency of furnaces and boilers, indicating the percentage of fuel converted into useful heat.

3. What are the common causes of air leakage in homes, and how can they be addressed?

• Attic: Inspect and seal gaps around attic access hatches, vents, and pipes.
• Walls: Check for gaps around windows, doors, and electrical outlets, and use caulk or weatherstripping to seal them.
• Basement: Seal cracks in the foundation, around pipes, and at the rim joists.
• Crawl Space: Install vapor barriers and seal any openings to prevent air leakage from the ground.

4. How do you determine the appropriate insulation levels for a home in a specific climate zone?

• Climate Zone Classification: Refer to industry standards and building codes to identify the climate zone for the home’s location.
• Building Envelope Characteristics: Consider the home’s size, shape, and type of construction when selecting insulation materials and R-values.
• Energy Code Compliance: Ensure that insulation levels meet or exceed minimum requirements set by local building codes and energy efficiency programs.

5. Describe the principles of passive solar design, and provide examples of how they can be applied to a home.

• Orientation: Position the home on the lot to maximize exposure to sunlight during winter months and minimize heat gain during summer months.
• Windows: Install large, south-facing windows to capture solar heat during the winter, and consider installing overhangs or awnings to block excess heat during the summer.
• Thermal Mass: Use materials such as concrete, brick, or stone to absorb and store solar heat during the day and release it gradually at night.

6. How can you assess the indoor air quality of a home, and what are some common issues that can be identified?

• Indoor Air Quality Monitoring: Use devices such as air quality monitors or radon detectors to measure levels of pollutants, such as particulate matter, volatile organic compounds (VOCs), and radon.
• Visual Inspection: Check for signs of mold, mildew, or water damage, which can indicate moisture issues and air quality problems.
• Symptom Assessment: Ask occupants about any symptoms they are experiencing that may be related to indoor air quality, such as allergies, asthma, or headaches.

7. How do you prioritize energy efficiency improvements for a home, considering both cost and potential energy savings?

• Cost-Benefit Analysis: Calculate the estimated cost of each improvement and compare it to the projected energy savings.
• Prioritization by Impact: Focus on improvements that offer the greatest potential energy savings, such as air sealing, insulation, and efficient heating and cooling systems.
• Phased Approach: Break down large-scale projects into smaller, manageable phases to spread out the costs and prioritize the most impactful improvements first.

8. What is your approach to communicating complex technical information to clients in a clear and understandable way?

• Use Plain Language: Avoid technical jargon and use clear, everyday language that clients can easily comprehend.
• Visual Aids: Employ diagrams, charts, and graphics to help illustrate concepts and make information more accessible.
• Active Listening: Pay attention to clients’ questions and concerns, and adjust explanations as needed to address specific needs.

9. How do you stay up-to-date on the latest trends and advancements in home performance technology?

• Industry Events and Conferences: Attend industry conferences, workshops, and trade shows to learn about new technologies and best practices.
• Professional Development: Engage in continuing education courses, certifications, and webinars to expand knowledge and skills.
• Industry Research: Read industry publications, journals, and white papers to stay informed on the latest innovations and research findings.

10. Provide an example of a successful project where you implemented energy efficiency measures in a home, and quantify the results achieved.

• Description of Project: Briefly outline the scope of the project, including the type of home and the improvements implemented.
• Energy Savings: Quantify the estimated or measured energy savings achieved, such as a percentage reduction in energy consumption or utility bills.
• Client Impact: Describe the positive impact the improvements had on the client, such as increased comfort, improved indoor air quality, or financial savings.
