Build Science #4: Efficiency and Environmental Responsibility

Energy Efficiency: A Two-Headed Monster

Energy efficiency in buildings is like a two-headed monster. The first head is about acquiring energy (be it gas, electricity, or oil) at the lowest possible rate. The second head involves effectively retaining that energy within our buildings. This dual approach is essential for creating energy-efficient homes, especially in varied climates like Texas.

Understanding Heat Flow

A fundamental principle in building science is that heat moves from hot to cold. This concept is crucial when designing a home. For example, in Texas, we deal with both hot summers and mild winters. Our building designs need to manage the temperature deltas effectively, whether it's a 30° delta in summer or a 15° delta in winter.

Passive Solar Design

Passive solar design is a technique where we use the house's orientation and design to harness sunlight for heating. It's a method often used in colder regions to reduce purchased energy needs. However, this must be carefully balanced with the need for cooling in warmer seasons and regions.

Environmental Responsibility: Beyond Building

Building a house inevitably impacts the environment. Every construction project incurs an environmental debt, whether it's through resource usage or alteration of land. As builders, we must make conscientious decisions to minimize this impact.

Durability vs. Environmental Responsibility

Durability in building ties directly into environmental responsibility. A durable home minimizes resource waste and energy consumption over time. Hence, choosing materials and designs that last longer contributes significantly to environmental sustainability.

Embodied Energy in Materials

The concept of embodied energy plays a crucial role in our material choices. Embodied energy refers to the total energy required to produce a building material. By opting for materials with lower embodied energy, like locally sourced white oak over luxury vinyl tile, we reduce the overall environmental impact of our projects.

Making Moral Choices in Building

As builders, we often face decisions that aren't just about adhering to codes but making moral choices. These choices might involve opting for more sustainable materials or techniques that may not be the easiest or cheapest but are right for the environment.

Building for the Future

In conclusion, efficiency and environmental responsibility in building are about making informed choices. It's about understanding the principles of building science, the impact of our actions on the environment, and striving to create homes that are not only comfortable and durable but also respectful of the world we live in.

Next, in our series, we will explore "Where is Building Science," delving into how building science principles are applied in various aspects of construction and design.
