What is "Glass-House" Architecture?
“Glass-House” Architecture refers to facilities, restaurants, buildings, and any other indoor space designed with glass (typically), and focused on natural lighting and plant life, in order to create a beautiful space for people to gather. While glass is typically the glazing material used, it is not required, and not always the most appropriate glazing material.
As opposed to a “greenhouse”, a “glass house” is mainly intended to be a space for people, the greenery being secondary. A greenhouse, on the other hand, is usually the other way around.
Ceres has partnered with European Manufacturer Rabensteiner to provide such glasshouse architecture as: atriums, conservatories, solariums, sunrooms, and beautiful community spaces that are all energy-efficient and can be used for such applications as restaurants and community centers.
*At this time we are not designing or providing glass-houses for smaller residential projects.
We are leaders in energy efficient, passive solar design. We are committed to helping our clients every step of the building process to ensure both a beautiful design and maximum energy efficiency.
We offer: Ceres provides North American engineering, stamping, and climate control (including design integration). We work alongside an architect for a smooth permitting process and for full interior design.
"Glass" or "Green" house?
We understand that there is a spectrum of needs and functions for each individual and business’s use of a greenhouse or glass-house. A client might wish for a glasshouse, and then decide the primary function is for plants; and vice versa for a greenhouse. We will work with you to decide the best option and potential customizations to work with your needs, now and in the future.

We offer Ceres designed EcoLoop™ or EcoPack™ HVAC options depending on growing goals, budget, site constraints, and greenhouse type. All Ceres environmental controls are custom integrated to suit your needs.
The GAHT® system is a ground to air heat exchanger, a system often referred to as a ‘Climate Battery’. Ceres leads the industry in climate battery technology, having designed and installed more systems in greenhouses than any other company in the world.
Different crops may demand specific lighting requirements. We offer a variety of lighting solutions designed to suit the needs of each individual operation.
A NetZero greenhouse will have zero net emissions. This goal is achieved through capturing and storing energy. This can be done using a various system options.
Ethylene tetrafluoroethylene is a durable, high light transmissive glazing option. It offers more than 95% light transmission, including the UV spectrum. More than other greenhouse companies, Ceres is implementing full spectrum glazings for maximum crop growth.
Glass Architecture FAQs
Ceres will provide the following:
- building shells (glass or not)
- appropriate climate control and lighting
Ceres will aid in the architectural design, but will need to also work with an external architect to address the functions of the building that are dedicated to people.
Glass-Houses, especially larger structures of 5000 sqft (500m2) and more are often custom structures. Our partner, Rabensteiner, specializes in the design and manufacturing of materials for custom Glass House structures. Ceres will help North American and international customers and customers’ architects with the design process, permitting, foundation and civil engineering, climate control and lighting, water treatment and the project management all the way to completion.
Clients that are looking to add more value per area of glass house, such as:
- Events (such as weddings, and culinary events)
- Corporate meetings (especially companies that want to show their dedication to the environment)
- Corporate campuses
- Hospitals and other places of healing
- Retreat centers (such as meditation centers)
- Universities and schools (that want to show a connection to the world outside of their walls)
The list is long and can include places where animals and people can spend time together.
Depending on the use of the Glass House, architects are essential for the success of the project. In particular applications, specialized architects might be needed to bring the project to fruition (i.e supermarkets, zoos, etc.). It is also good to have a local architect firm involved in a permitting process. If needed, Ceres is working with highly qualified architects if the client requires help finding an appropriate partner.
Ceres is available to answer any questions to get your project started. We are happy to assist in finding a great architect, and happy to work with any architect worldwide. We also have many foreign speakers, so assisting in other languages may be possible.
The cost of the Glass House depends on the size of the building, its usage, and the climate control equipment and controls needed. In general, Ceres estimates that the Glass House will be in a similar price range to most nice looking commercial buildings.
Ceres can design and deliver any size Glass House structure. In cooperation with our partner Rabensteiner, we are looking at the sum of the erected area of about 5000 sqft (450m2).
Smaller Glass Houses shall be designed by Ceres only.
One option is to install a solar panel system to run the electrical components.
You can also build a completely passive solar greenhouse – one that does not use any electrical components. For this we recommend using passive solar vent openers to provide automated ventilation. There are several pros and cons to building a passive solar greenhouse vs. an active one. Much more information on solar panel systems and passive solar greenhouse is in our book, The Year-Round Solar Greenhouse as well as “Integrating Solar Panels into the Greenhouse.”
Ceres Glass Houses are designed to withstand snow, wind, hail and seismic requirements provided by the local building code.
Glass House clients and their architects should speak with their building department about zoning requirements. These buildings are often classified as mixed-use buildings instead of purely commercial agriculture or purely commercial.
Sometimes special energy savings calculations/documentation is needed because Glass Houses do not fit the general guidelines for required building insulation. A Glass House can be very energy-efficient using multi-layer glass, solar panels between the glass, phase change materials, a GAHT® system, movable insulation etc., even if the glass panels themselves are not rated as high as insulated walls.
The project timeline is often most dependent on the funding, design and permitting process. The actual building time is relatively short. Ceres and its partners will provide project oversight to assure that the building is built correctly and efficiently. Erection times of the steel and glass can be relatively short and completed in approximately 2 months.
A Glass House can be very energy efficient, even net zero and electric only, using multi-layer glass, solar panels between the glass (PV), solar thermal panels and radiant floor heating, phase change materials, a GAHT® system and movable insulation etc.
As seen in many of the examples on the web page above, Ceres expects that most projects will have a combination of traditional buildings such as: kitchens, offices, storage spaces, coolers, etc.
Rooftop Glass Houses are one of the most exciting applications. Rooftops are very economical spaces where a Glass House can add a significant value to the underlying building. The increase of the value of the underlying building will reduce the value that the Glass House needs for it to be built. This is usually a win/win situation.
In urban spaces, a Glass House, similar to a wonderful supermarket or a commuter rail stop, will absolutely increase the value of all surrounding properties.
The same is true for adult living facilities, community centers, recreation centers, town halls, libraries, etc.
