This document provides information about Granada Secondary Glazing, a UK-based specialist in secondary glazing systems. It summarizes Granada's products and services, highlighting that they design, manufacture, and install secondary glazing solutions that improve noise insulation, thermal efficiency, and security while respecting historic building aesthetics. Granada has a wide range of products and extensive experience supporting renovation projects across various sectors, particularly for heritage and listed buildings.
This document summarizes a presentation given at the iCon Environmental Innovation Centre on June 30, 2011 about new business opportunities in the low carbon economy. It discusses Patrick Bellew's work at Atelier Ten designing sustainable, low energy buildings using pioneering approaches like thermal labyrinths and earth duct technology. It also presents several case studies of high-performance buildings designed by Atelier Ten that achieved low carbon conditioning through strategies like geothermal heating/cooling and displacement ventilation. Finally, it summarizes Atelier Ten's design of the Cool-Dry conservatory for Gardens by the Bay in Singapore, which maintains optimal temperature and humidity for plants through biomass-powered dehumidification and cooling.
Riba South Sustainability Through Envelope EfficiencyMatt Robinson
The document discusses issues with building efficiency in the UK construction industry and proposes solutions to improve building performance. It notes that UK buildings often use significantly more energy than predicted and fail to meet air infiltration standards. Thermal bridging, insulation levels, and air leakage are identified as key areas of non-compliance. The solution is outlined as focusing on building envelope efficiency through high insulation values, low thermal bridging, and air tightness, which can reduce heating and cooling loads by 80%. Renewables and technology provide the remaining 20% of efficiency.
Timber frame construction can be used to build low or zero carbon housing by achieving high levels of insulation and airtightness. Passive houses require air infiltration rates below 0.03 air changes per hour and use heat recovery ventilation systems. Using increased insulation, achieving air tightness of less than 0.1 air changes per hour, and integrating solar technology and heat recovery ventilation can allow timber frame homes to meet future regulations requiring homes that use 62 kWh/m2 or less per year. Proper workmanship will be important to ensure high performance.
This document summarizes a 200 house development in Killeagh, Co. Cork that aims to be low energy and low carbon. Key points:
1) The development will feature highly insulated and airtight construction, with solar panels and a heat recovery ventilation system to reduce energy demands. Wood pellet boilers will provide backup heating.
2) Calculations show the design will save over 95% of CO2 emissions compared to standard homes.
3) The developer sought a design not reliant on oil or gas to future-proof against price fluctuations. The integrated systems aim to provide comfortable, low-cost heating and hot water.
Dimplex Air Curtain, Air Heaters, Radiant Heaters & Fan Heaters - BrochureThorne & Derrick UK
The document discusses Dimplex air curtains and their ability to provide energy savings of up to 30% for buildings. It explains that air curtains help maintain interior temperatures by reducing the amount of heated or cooled air that escapes through doors. This leads to lower running costs and a more comfortable environment while allowing for open access. The document provides several examples and specifications of Dimplex air curtain models and their performance in reducing carbon emissions and energy bills for commercial buildings.
Greenline windows and doors are manufactured specifically for the US and comply with all building code requirements for the state of Florida. The Miami / Dade High Velocity / Hurricane Zone (HV/HZ) code has been adopted nationwide as the benchmark for severe weather protection and is accepted by most municipalities around the US.
The document discusses the concept of passive solar houses and passive houses. It provides examples of early passive solar houses built in Ireland in the 1970s-1980s, which did not meet modern standards for air-tightness, insulation and minimizing thermal bridges. The passive house standard developed in Germany in the 1990s requires ultra-high insulation (U-values <=0.15 W/m2K), minimized thermal bridges, high air-tightness (<=0.6 air changes/hour) and heat recovery ventilation. Meeting this standard poses challenges, particularly the required air-tightness, and may result in low indoor humidity in winter. Simpler passive solar house designs can still achieve low energy usage.
This document discusses switchable variable-tint electrochromic windows that can be installed in commercial building facades. It notes that windows are a major source of heat loss from buildings. Electrochromic windows allow occupants to control their comfort levels by adjusting the tint of the windows. Installing these windows on the three main facades of a hypothetical commercial building could save up to £17,000 per year in London and £7,000 per year in Glasgow by reducing energy costs. However, the current high cost of around £450 per square meter means electrochromic glass would need to fall below £250 per square meter to be financially attractive compared to standard low-e glass.

Embodied Energy Saved In Converted Industrial BuildingsMark1865
Rehabilitating old industrial buildings in Scotland saves embodied energy compared to demolishing them and building new structures. Existing buildings already have energy invested in their construction materials and can be adapted for new uses. Refurbishing buildings retains this embodied energy and avoids the energy costs of demolishing existing structures and bringing in new building materials. Whole life costing and life cycle assessments further demonstrate the energy savings of reusing and retrofitting historic buildings over new construction.
The document discusses ways for ONCA, an art center located in a listed Georgian building, to improve its energy efficiency and reduce its energy bills. It identifies the major source of energy loss as the building's windows, which have many gaps. It recommends some lower-cost methods like caulking windows and applying plastic film to trap air as short-term solutions. More expensive options include installing double-glazed windows long-term or attic insulation. Correspondence with the local council provides guidance on acceptable energy efficiency upgrades for listed historic buildings that preserve historical integrity.
