Thermal Mass Construction
How Thermal Mass Works...
Warmth in winter. Comfort in summer.
Canterbury’s seasonal sunlight is considered from the beginning of the design process.
In winter, the lower sun can reach the internal concrete through correctly positioned glazing. The concrete absorbs this free solar warmth during the day and gently releases it later as indoor temperatures begin to fall.
In summer, the higher sun is controlled by well-designed eaves, shading and glazing. When protected from direct sunlight, the concrete helps absorb excess indoor heat, while night ventilation can release accumulated warmth.
1. Absorb
Concrete absorbs heat from winter sunlight, people and everyday household activity.
2. Store
Its high density stores this energy and slows rapid changes in indoor temperature.
3. Release
As the room cools, the stored warmth is gradually released back into the living space.

A Monolith Design and Build home uses the natural heat-storage capacity of concrete to create a more stable indoor climate—warmer when Canterbury cools and cooler when summer temperatures rise
What Is Thermal Mass?
Thermal Mass is a natural thermal battery, built into your home.
Thermal mass is a material’s ability to absorb, store and gradually release heat.
Dense materials such as concrete have high thermal mass. Their temperature changes slowly, helping to moderate the peaks and dips that can occur in lightweight homes.
In a thoughtfully designed Monolith home, exposed concrete floors, walls and ceilings become part of the comfort system. They absorb useful solar warmth during the day and gradually release it as the air cools.
During summer, carefully designed shading prevents direct sunlight from overheating the concrete, allowing it to help absorb excess warmth from inside the home.

Comfort Held in Concrete
More Stable Temperatures
Concrete moderates the difference between warmer daytime temperatures and cooler nights, creating a more consistent indoor environment
Reduced Heating and Cooling Demand
By smoothing temperature fluctuations and reducing peak indoor temperatures, thermal mass can reduce reliance on mechanical heating and cooling.
Free Winter Solar Gain
Correctly oriented glazing allows winter sunlight to reach internal concrete surfaces, where its warmth can be stored and released later.
Long-Life Performance
Thermal capacity is an inherent property of concrete. It does not rely on complicated technology and remains part of the home throughout its life.
Improved Summer Comfort
Appropriate shading protects the concrete from direct summer sun. The cooler thermal mass can then absorb excess heat from the rooms around it.
A Healthier-Feeling Home
Appropriate shading protects the concrete from direct summer sun. The cooler thermal mass can then absorb excess heat from the rooms around it.
Comfort is a Complete System
Concrete does not provide a food source for mould, pests or decay. Its durability and solid construction can also reduce the number of concealed cavities commonly found in lightweight building systems. A genuinely healthy indoor environment depends on the complete design of the home. Effective ventilation, moisture management, insulation, airtightness and carefully selected low-emission finishes must all work together.
At Monolith Design Build, these elements are considered as one integrated building system.
Every Monolith home is designed around its individual site, the Canterbury climate and the needs of the people who will live there.
